E Flashcards
1
Q
The organ of hearing and balance
- In humans and other mammals the ear is divided into external, middle, and inner sections
- The pinna of the external ear collects sounds that are then funneled through the external auditory meatus to the tympanic membrane
- The sounds are vibrations of air molecules that cause the tympanic membrane to vibrate, which in turn vibrates the ossicles, three tiny bones in the middle ear
- The motion of the last of these bones produces pressure waves in the fluid filled cochlea of the inner ear
- The motion of the fluid in the cochlea is converted by specialized receptors called hair cells into neural signals that are sent to the brain by the auditory nerve
A
Ear
2
Q
A collection of specialized services provided to children from birth to 3 years of age with identified conditions placing them at risk of developmental disability or with evident signs of developmental delay

A
Early Intervention
3
Q
Any theory of attention proposing that selection of stimuli for in depth analysis occurs early in the processing stream, prior to stimulus identification
- According to this, unattended stimuli receive only a slight degree of processing that does not encompass meaning, whereas attended stimuli proceed through a significant degree of deep, meaningful analysis

21
Q
A phenomenon whereby people come to evaluate a particular task or activity more favorably when it involves something that is difficult or unpleasant

- This is in contrast to ID psychology, which focuses on the primitive instincts of sex and hostility
Ego Psychology
31
In psychoanalytic theory, the ability of the ego to maintain an effective balance between the inner impulses of the ID, the superego, and outer reality
- An individual with a strong ego is thus one who is able to tolerate frustration and stress, postpone gratification, modify selfish desires when necessary, and resolve internal conflicts and emotional problems before they lead to neurosis
Ego Strength
32
Excessive conceit or excessive preoccupation with one's own importance
Egotism
33
In psychoanalytic theory, the inability of the ego to control impulses and tolerate frustration, disappointment, or stress

- These are of central importance in linear algebra (ie; matrix algebra)
Eigenvalue
36
An expectation or readiness associated with particular stimuli
- It may foster a degree of mental inflexibility by instilling a tendency to respond to a situation in a certain way
- For example, a person who successfully solves a series of problems using one formula may apply that same formula to a new problem solvable by a simpler method
- The contemporary term for this concept is mental set [German: "attitude"]

Elaborated Code
38
1. The process of interpreting or embellishing information to be remembered or of relating it to other material already known and in memory
- The levels of processing model of memory holds that the level of elaboration applied to information as it is processed affects both the length of time that it can be retained in memory and the ease with which it can be retrieved
2. The process of scrutinizing and thinking about the central merits of attitude- relevant information
- This process includes generating inferences about the information, assessing its validity, and considering the implications of evaluative responses to the information
Elaboration
39
A theory of persuasion postulating that attitude change occurs on a continuum of elaboration and thus, under certain conditions, may be a result of relatively extensive or relatively little scrutiny of attitude relevant information

A type of connection in which neurons are not separated by a cleft but instead are joined by a gap junction so that the nerve impulse is transmitted across without first being translated into a chemical message
Electrical Synapse
46
A wavelike tracing, either printed or displayed on a monitor, that represents the electrical impulses of the conduction system of the heart muscle as it passes through a typical cycle of contraction and relaxation
- The electrical currents are detected by electrodes attached to specific sites on the patient's chest, legs, and arms and recorded by an instrument, the electrocardiograph
- In the procedure, which is called electrocardiography, the wave patterns of the electrocardiogram reveal the condition of the heart chambers and valves to provide an indication of cardiac problems
Electrocardiogram
47
A controversial treatment in which a seizure is induced by passing a contrived, low dose electric current through one or both temples
- The patient is prepared by administration of an anesthetic and injection of a muscle relaxant

57
A developmental stage that is neither adolescence nor young adulthood but is theoretically and empirically distinct from them both, spanning the late teens through the twenties, with a focus on ages 18-25
- It is distinguished by relative independence from social roles and from normative expectations
- Having left the dependency of childhood and adolescence, and having not yet entered the enduring responsibilities that are normative in adulthood, they engage in identity exploration, a process of trying out various life possibilities (eg; in love, work, and worldviews) and gradually moving toward making enduring decisions
Emerging Adulthood

Denoting an approach to the study of human cultures that interprets behaviors and practices in terms of the system of meanings created by and operative within a particular cultural context
- Such an approach would generally be of the kind associated with ethnography rather than ethnology
Emic
59
A natural response that is not influenced by, or dependent on, any external stimuli
Emitted Behavior
60
A complex reaction pattern, involving experiential, behavioral, and physiological elements, by which the individual attempts to deal with a personally significant matter or event
- The specific quality of the emotion (eg; fear, shame) is determined by the specific significance of the event
- For example, if the significance involves threat, fear is likely to be generated; if the significance involves disapproval from another, shame is likely to be generated
- This typically involves feeling but differs from feeling in having an overt or implicit engagement with the world
Emotion
61
Nonphysical abuse: a pattern of behavior in which one person deliberately and repeatedly subjects another to acts that are detrimental to behavioral and affective functioning and overall mental well being

Empirically Derived Test
70
1. An approach to epistemology holding that all knowledge of matters of fact either arises from experience or requires experience for its validation
- In particular, this denies the possibility of ideas present in the mind prior to any experience, arguing that the mind at birth is like a blank sheet of paper
- Although there is a strong emphasis on this in psychology, this can take different forms
- Some approaches to psychology hold that sensory experience is the origin of all knowledge and thus, ultimately, of personality, character, beliefs, emotions, and behavior
- Behaviorism is the purest form of this in this sense
- Advocates of other theoretical approaches to psychology, such as phrenomology, argue that the definition of experience as only sensory experience is too narrow
2. The view that experimentation is the most important, if not the only, foundation of scientific knowledge and the means by which individuals evaluate truth claims or the adequacy of theories and models

93
1. Enhancement or improvement by the addition or augmentation of some desirable property, quality, or component
- For example, job enrichment policies are designed to enhance quality of worklife and thus employees' interest in and attitude toward work tasks; marriage enrichment groups are intended to enhance the interpersonal relationships of married couples
2. The provision of opportunities to increase levels of behavioral or intellectual activity in an otherwise unstimulating (ie; impoverished) environment
- For example, the provision of play materials and opportunities for social contacts has been shown to enhance the development of young children
- In laboratory studies of animal behavior, the addition of physical features or task requirements to an environment elicits a more natural behavioral repertoire from the animals
Enrichment
94
The extent to which a group or collective is considered by others to be a real entity rather than a set of independent individuals
- In general, groups whose members share a common fate, are similar to one another, and are located close together are more likely to be considered a group rather than a mere aggregation

- Biological factors are considered to be of minor importance, exerting little, if any influence
Environmental Determinism
103
1. The concept that the environment and learning are the chief determinants of behavior
- They are, therefore, the major cause of interpersonal variations in ability and adjustment; accordingly, behavior is largely modifiable

Environmentalism
104
A model of stress and adaptation in which adaptive functioning in the environment depends on the interaction between stimuli in a person's physical and social environment that interact with needs and place demands on that individual (environmental press) and the individual’s competence in meeting these demands, which is shaped by such personal characteristics as physical health and cognitive and perceptual abilities
Environmental Press Competence Model
105
A multidisciplinary field that emphasizes the reciprocal effects of the physical environment on human behavior and welfare

- Results of epidemiological studies are intended to find clues and associations rather than necessarily to show causal relationships
Epidemiology
110
1. The theory that characteristics of an organism, both physical and behavioral, grise from an interaction between genetic and environmental influences rather than from one or the other
2. In genetics, the occurrence of a heritable change in gene function that is not the result of a change in the base sequence of the organism's DNA
Epigenesis
111
A common neurological disorder associated with disturbances in the electrical discharges of brain cells and characterized by recurrent seizures that may be manifested as alterations in sensation, motor functions, and consciousness
- Many forms of this have been linked to viral, fungal, or parasitic infections of the central nervous system; known metabolic disturbances; the ingestion of toxic agents; brain lesions; tumors or congenital defects; or cerebral trauma
- Types of seizure vary depending on the nature of the abnormal electrical discharge and the area of the brain affected
Epilepsy
112
A catecholamine neurotransmitter and adrenal hormone that is the end product of the metabolism of the dietary amino acid tyrosine
- It is synthesized primarily in the adrenal medulla by methylation of norepinephrine, which itself is formed from dopamine
- As a hormone, it is secreted in large amounts when an individual is stimulated by fear, anxiety, or a similar stressful situation
- As a neurotransmitter, it increases the heart rate and force of heart contractions, relaxes bronchial and intestinal smooth muscle, and produces varying effects on blood pressure as it acts both as a vasodilator and vasoconstrictor
Epinephrine
113
A mere byproduct of a process that has no effect on the process itself
- The term is used most frequently to refer to mental events considered as products of brain processes
- Thus, while mental events are real in some sense, they are not real in the same way that biological states and events are real, and not necessary to the explanation of mental events themselves
- This is conceived of as having no causal power
Epiphenomenon
114
Memory for specific, personally experienced events that happened at a particular time or place
- This supplements semantic memory and may decline with normal aging
Episodic Memory
115
The branch of philosophy concerned with the nature, origin, and limitations of knowledge
- it is also concerned with the justification of truth claims
- In psychology, interest in epistemology crises from two principal sources
- first, as the study of the behavior of numer beings, psychology has long had interest in the process of knowledge acquisition and learning of all sorts
- second, as a science, psychology has an interest in the justification of its knowledge claims
- In connection with this concern, most work on epistemology in psychology as concentrated on scientific method

Equilibrium Potential
120
The generalization by U.S. Psychologist Karl S. Lashley (1890-1958) that large areas of cerebral cortex have equal potential to perform particular functions, being equally involved in learning and certain other complex processes, such that intact cortical areas can assume to some extent the functions of damaged or destroyed areas
- Proposed in 1929 following experimental observations of the effects of different brain lesions on rats’ ability to learn a complex maze, the concept has been challenged by subsequent research showing that areas of cortex have relatively specific functions
Equipotentiality
121
A theory of justice regarding what individuals are likely to view as a fair return from activities involving themselves and a number of other people
- The theory posits that people compare the radio of the outcome of the activity (ie; the benefits they receive from it) to their input with the outcome to input radios of those engaged in a comparable activity

- The stages are: (a) infant: basic trust versus mistrust; (b) toddler: autonomy versus shame and doubt; (c) preschool age: initiative versus guilt; (d) school age: industry versus inferiority; (e) adolescence: identity versus identity confusion; (f) young adulthood: intimacy versus isolation; (g) middle age: generativity versus stagnation; and (h) older adulthood: integrity versus despair
Erikson's Eight Stages of Development
124
An area or part of the body sensitive to stimulation that is a source of erotic or sexual feeling or pleasure
- Among the primary zones are the genitals, buttocks and anus, the breasts (especially the nipples), and the mouth
Erogenous Zone
125
The God of love in Greek mythology (equivalent to the Roman Cupid), whose name was chosen by Austrian psychoanalyst Sigmund Freud (1856 - 1939) to designate a theoretical set of strivings oriented toward sexuality, development, and increased life activity
- In Freud's dual instinct theory, this is seen as involved in a dialetic process with Thanatos, the striving toward reduced psychical tension and life activity
Eros
126
1. In experimentation, any change in a dependent variable not attributable to the manipulation of an independent variable
2. In statistics, a deviation of an observed score from a true score, where true score is often defined by the mean (average) of the particular group or condition in which the score being assessed for error occurs, or from the score predicted by a model
Error
127
The element of a statistical equation that indicates what is unexplained by the independent variables
Error Term
128
Unexplained variability in a score that is produced by extraneous factors, such as measurement imprecision, and is not attributable to the independent variable or other controlled experimental manipulations
Error Variance
129
The process in which a subject acquires a response that results in the termination of an aversive stimulus
- For example, it a monkey learns that pulling a string frequently results in the elimination of a loud noise, this has occurred
Escape Conditioning
130
In philosophy, the position that things for some things) have "essences"; that is, they have certain necessary properties without which they could not be the things they are
- In Marxism, postmodernism, poststructuralism, and certain feminist perspectives, it is the rejected position that human beings have an essential nature that transcends such factors as social class, gender, and ethnicity
Essentialism
131
Any desire for achievement, reputation, or prestige that is necessary for a sense of personal value and the development of self esteem
- Comprising the fourth level of Maslow’s motivational hierarchy, these thus are dependent upon the admiration and approval of others
Esteem Need
132
The measurement of sensitivity to touch
- Classically, two different versions of an instrument called an esthesiometer have been used
- One consists of bristles of different lengths and thickness that are applied to determine the minimum pressure intensity required to produce a sensation
- The other is a compass like device to determine the smallest separation distance at which two points of stimulation on the skin are perceived as one
- More sophisticated techniques have not been developed, such as those involving electrodes
Esthesiometry (Aesthesiometry)
133
A quantity calculated from the values in a sample according to some rule and used to give an estimate of the value in a population
- For example, the sample mean is an estimator for the population mean; the verve of the sample mean is the estimate
Estimator
134
Any of a class of steroid hormones that are produced mainly by the ovaries and act as the principal female sex hormones, inducing estrus in female mammals and secondary female sexual characteristics in humans
- The estrogens occurring naturally in humans are estradio (the most potent), estrone, and estriol, secreted by the ovarian follicle, corpus luteum, placenta, testes, and adrenal cortex
Estrogen
135
The cyclical sequence of reproductive activity shown by most female mammals (except humans and other primates)
- Animals that experience one estrous cycle per year are called monstrous; those that have multiple estrous cycles annually are polyestrous
Estrous Cycle
136
A substance formed by the fermentation of glucose and found in beverages such as beers, wines, and distilled liquors
- It is the most frequently used and abused depressant in many cultures
- When consumed its primary effects are on the central nervous system, mood, and cognitive functions
- In small doses, it can produce feelings of warmth, well being, and confidence
- As more is consumed, there is a gradual loss of self control, and speech and control of limbs become difficult; at high consumption levels, nausea and vomiting, loss of consciousness, and even fatal respiratory arrest may occur
- It has been mistakenly identified as a stimulant, since its stimulating effect derives from an associated loss of cortical inhibition
Ethanol
137
1. The branch of philosophy that investigates both the content of moral judgements (ie; whether such judgements should be considered objective or subjective)
2. The principles of morally right conduct accepted by a person or a group or considered appropriate to a specific field (eg; medical ethics, ethics of animal research)
Ethics
138
Denoting or referring to a group of people having a shared social, cultural, linguistic, religious, and usually racial background
Ethnic
139
Any major social group that possesses a common ethnic identity based on history, culture, language, and, often, religion
- Members are likely to be biologically related, but an ethnic group is not equivalent to a race
Ethnic Group
140
An individual’s sense of being a person who is defined, in part, by membership in a specific ethnic group
- This sense is usually considered to be a complex construct involving shared social, cultural, linguistic, religious, and often racial factors but identical with none of them
Ethnic Identity
141
The tendency to reject and malign other ethnic groups and their members while glorifying one's own group and its members
- Just as egocentrism is the tendency to judge oneself as superior to others, so ethnocentrism is the parallel tendency to judge one's group as superior to other groups
Ethnocentrism
142
The descriptive study of cultures or societies based on direct observation and (ideally) some degree of participation
Ethnography
143
The comparative, analytical, or historical study of human cultures or societies
Ethnology
144
The analysis of the underlying conventions and systems of meaning that people use to make sense of commonplace social interactions and experiences
Ethnomethodology
145
A detailed listing and description of the behavior patterns of an animal in its natural habitat
- The description is objective rather than interpretive
- For example, a vocalization given in response to a predator would be described in terms of its acoustic properties rather than its apparent function of alarm call
Ethogram
146
The comparative study of the behavior of animals, typically in their natural habitat but also involving experiments both in the field and in captivity
- It is often associated with connotations of innate or species specific behavior patterns, in contrast with comparative psychology
Ethology
147
Denoting an approach to the study of human cultures based on concepts or constructs that are held to be universal and applicable cross culturally
- such an approach would generally be of the kind associated with ethnology rather than ethnography
Etic
148
1. The causes and progress of a disease or disorder
2. The branch of medical and psychological science concerned with the systematic study of the causes of physical and mental disorders
Etiology
149
A social and political philosophy that seeks to eradicate genetic defects and improve the genetic makeup of populations through selective human breeding
- The eugenic position is groundless and scientifically naive, in that many conditions associated with disability or disorder are inherited recessively and occur unpredictably
Eugenics
150
An elevated mood of well being and happiness
- An exaggerated degree of this that does not reflect the reality of one's situation is a frequent symptom of manic episodes and hypomanic episodes
Euphoria

Eustachian Tube
152
The positive stress response, involving optimal levels of stimulation: a type of stress that results from challenging but attainable and enjoyable or worthwhile tasks (eg; participating in an athletic event, giving a speech)
- It has a beneficial effect by generating a sense of fulfillment or achievement and facilitating growth, development, mastery, and high levels of performance
Eustress
153
The act or process of terminating a life to prevent further suffering
- It is distinguished from the much more widely accepted practice of forgoing invasive treatments, as permitted under natural death laws throughout the United States
- Traditionally, a distinction between passive euthanasia (witholding treatment) and active euthanasia (taking directly lethal action) has been made
- In current practice, however, this term typically is used to mean active euthanasia only
Euthanasia
154
A careful examination or overall appraisal of something, particularly to determine its worth, value, or desirability
- For example, the evaluation of a particular therapeutic technique refers to a determination of its success in achieving defined goals
Evaluation

Evaluation Apprehension
156
A specific pattern of electrical activity produced in the brain when a person is engaged in a cognitive act, such as discriminating one stimulus from another
- There are a number of different ERP components, and different cognitive operations have been associated with the amplitude and latency of each
- Because ERPs provide specific information about the precise timing and (given appropriate caveats) location of mental events, they serve as an appropriate bridge between psychological function and neural structures
- Although the terms are sometimes used synonymously, ERPs are distinct from evoked potentials, which are associated with more elementary sensory stimulation
Event Related Potential (ERP)
157
A strategy commonly used in direct observation that involves noting and recording the occurrence of a carefully specified behavior whenever it is seen
- For example, a researcher may record each episode of apnea that occurs within a 9 hour period overnight while a person sleeps
Event Sampling
158
The integration of the best available scientific research from laboratory and field settings with clinical expertise so Es to provide effective psychological services that are responsive to a patient's culture, preferences, and characteristics (eg; functional status, level of social support, strengths)
- In uniting researchers and practicioners, EBP ensures that the research on psychological assessment, case formulation, intervention strategies, therapeutic relationships and outcomes, and specific problems and patient populations is both clinically relevant and internally valid
- Clinical decisions should be made in collaboration with the patient, based on relevant data, and with consideration for the probable costs, benefits, and available resources and options
- The ultimate goal of EBP is to promote empirically supported principles that can be used to enhance public health
Evidence Based Practice (EBP)
159
A specific pattern of electrical activity produced in a particular part of the nervous system, especially the brain, in response to external stimulation, such as a flash of light or a brief tone
- Different modalities and types of stimuli produce different types of sensory potentials, and these are labeled according to their electrical polarity (positive or negative going) and timing (by serial order or in miliseconds)
- Although the terms are sometimes used synonymously, EPs are distinct from event related potentials, which are associated with higher level cognitive processes
Evoked Potential (EP)
160
The process of gradual change in the appearance of populations of organisms that has taken place over generations
- Such changes are widely held to account for the present diversity of living organisms originating from relatively few ancestors since the emergence of life on earth
Evolution

An increase in the severity of a disease or disorder or of its symptoms
Exacerbation
163
The electrical activity elicited in a neuron or muscle cell in response to an external stimulus, specifically the propagation of an action potential
Excitation
164
The theory that emotional responses can be intensified by arousal from other stimuli not directly related to the stimulus that originally provoked the response
- According to this theory, when a person becomes aroused physiologically, there is a subsequent period of time when the person will experience a state of residual arousal yet be unaware of it
- If additional arousing stimuli are presented during this time, the individual will experience more arousal, and thus greater response, to those succeeding stimuli than if there had been no residual arousal
Excitation Transfer Theory
165
A brief decrease in the difference in electrical charge across the membrane of a neuron that is caused by the transmission of a signal from a neighboring neuron across the synapse (specialized junction) separating them
- ESPs increase the probability that the postsynaptic neuron will initiate an action potential and hence fire a nerve impulse
Excitatory Postsynaptic Potential (ESP)
166
A specialized type of junction at which activity from one neuron (in the form of an action potential) facilitates activity in an adjacent neuron by initiating an excitatory postsynaptic neuron
Excitatory Synapse
167
Higher level cognitive processes that organize and order behavior, such as judgement, abstraction and concept formation, logic and reasoning, problem solving, planning, and sequencing of actions
- Deficits in executive functioning are seen in various disorders, including Alzheimer's disease and schizophrenia
- In the latter, for example, major deficits in such cognitive abilities as selecting goals or task relevant information and eliminating extraneous information are apparent and are a focus of neurorehabilitative treatment
Executive Functions
168
A paraphilia in which a person repeatedly exposes his or her genitals to unsuspecting strangers as a means of achieving sexual satisfaction
Exhibitionism
169
A general sense of anguish or despair associated with an individuals recognition of the inevitability of death and associated search for purpose and meaning in life, in light of the finitude of past choices and the unknowns inherent to future choices

Existential Humanistic Therapy
171
A philosophical and literary movement that emerged in Europe in the period between the two world wars and became the dominant trend in Continental thought during the 1940s and 1950s
- In the immediate postwar years French philosopher and author Jean-Paul Sartre (1905 - 1980), who is usually seen as the existentialist thinker par excellence, popularized both the term "existentialism" and most of the ideas now associated with it
- It represents a turning away from systematic philosophy, with its emphasis on metaphysical absolutes and principles of rational certainty, toward an emphasis on the concrete existence of a human being "thrown" into a world that is merely "given" and contingent
- Such a being encounters the world as a subjective consciousness, "condemned" to create its own meanings and values in an "absurd" and purposeless universe
- The human being must perform this task in the absence of any possibility of rational certainty
- Various forms of existential psychology have taken up the task of providing explanations, understandings of human behavior, and therapies based on existentialist assumptions about human existence
Existentialism
172
A pathological condition characterized by feelings of despair and anxiety that arise from living inauthentically, that is, from failing to take responsibility for one's own life and to make choices and find meaning in living

- It emphasizes the subjective meaning of human experience, the uniqueness of the individual, and personal responsibility reflected in choice
Existential Psychology
174
A form of psychotherapy that deals with the here and now of the client's total situation rather than with the client's past or underlying dynamics
- It emphasizes the exploration and development of meaning in life, focuses on emotional experiences and decision making, and stresses a person's responsibility for his or her own existence

Experimental Neurosis
189
1. In the late 17th and 18th centuries, a name for the new discipline of experimental science then emerging
- Use of the term often went with an optimism about the ability of experimental science to answer the questions that had been posed but unsolved by "natural philosophy”
- The systematic work of British physicist Isaac Newton (1642 - 1727) is often given as a defining example of the experimental philosophy
2. A late 20th century movement holding that modern experimental science, particularly neuroscience, will ultimately uncover the biological foundations of thought and thereby provide a material answer to the questions of epistemology
- In other words, this holds that answers to philosophical questions regarding the mind and its activities can, and likely will, be reduced to questions of how the brain functions
Experimental Philosophy
190
The scientific study of behavior, motives, or cognition in a laboratory or other experimental setting in order to predict, explain, or contra behavior or other psychological phenomena
- This aims at establishing quantified relationships and explanatory theory through the analysis of responses under various controlled conditions and the synthesis of adequate theoretical accounts from the results of these observations

191
The extent to which an experimental situation is meaningful and engaging to participants, eliciting responses that are spontaneous and natural
Experimental Realism
192
Research utilizing randomized assignment of participants to conditions and systematic manipulation of variables with the objective of drawing causal inference
- It is generally conducted within a laboratory or other controlled environment, which in reducing the potential influence of extraneous factors increases internal validity but decreases external validity
Experimental Research
193
An intervention or regimen that has shown some promise as a cure or ameliorative for a disease or condition but is still being evaluated for efficacy, safety, and acceptability
Experimental Treatment
194
An independent variable: a variable under investigation that is manipulated by the experimenter to determine its relationship to or influence upon some dependent variable
Experimental Variable

Experimenter Bias
196
Any influence an experimenter may have on the results of his or her research, derived from either interaction with participants or unintentional errors of observation, measurement, analysis, or interpretation
- In the former, the experimenter's personal characteristics (eg; age, sex, race), attitudes, and expectations directly affect the behavior of participants
- In the latter, the experimenter's procedural errors (arising from his or her predictions about results) have no effect on participant responses but indirectly distort the experimental findings
Experimenter Effect
197

Explanation
198
A relatively enduring and general evaluative response of which a person is consciously aware
Explicit Attitude
199
Long term memory that can be consciously recalled: general knowledge or information about personal experiences that an individual retrieves in response to a specific need or request to do so

Explicit Memory
200
One of a set of techniques used in factor analysis when strong theory is lacking and the observed data are freely explored in search of meaningful patterns among the observations
- That is, the data are examined in order to discover the underlying (latent) variables that explain the interrelationships among a larger set of observable (manifest) variables
Exploratory Factor Analysis
201
A form of behavior therapy that is effective in treating anxiety disorders
- This involves systematic confrontation with a feared stimulus, either in vivo (live) or in the imagination, and may encompass any of a number of behavioral interventions, including desensitization, flooding, implosive therapy, and extinction based techniques
- It works by (a) habituation, in which repeated exposure reduces anxiety over time by a process of extinction; (b) disconfirming fearful predictions; (c) deeper processing of the feared stimulus; and (d) increasing feelings of self efficacy and mastery
Exposure Therapy
202
Negative attitudes, in the form of criticism, hostility, and emotional overinvolvement, demonstrated by family members toward a person with a mental disorder
- High levels of this have been shown to be associated with poorer outcomes in mood, anxiety, and schizophrenic disorders and increased likelihood of relapse
Expressed Emotion (EE)
203

- A common expression of this is projection
2. The process of learning to distinguish between the self and the environment during childhood
Externalization
211
The extent to which the results of research or testing can be generalized beyond the sample that generated the results to other individuals or situations
- The more specialized the sample, the less likely it will be that the results are highly generalizable
External Validity
212
Sensitivity to stimuli that are outside the body, resulting from the response of specialized sensory cells called exteroceptors to objects and occurrences in the external environment
- This includes the five senses of sight, smell, hearing, touch, and taste, and exteroceptors thus take a variety of forms (eg; photoreceptors - retinal rods and cones - for sight; cutaneous receptors - Pacinian corpuscles, Meissner’s corpuscles, Merkel’s tactile disks - for touch)
Exteroreception
213
1. In Pavlovian conditioning: (a) A procedure in which pairing of stimulus events is discontinued, either by presenting the conditioned stimulus alone or by presenting the conditioned stimulus and the unconditioned stimulus independently of one another; or (b) the result of this procedure, which is a gradual decline in the probability and magnitude of the conditioned response

- It includes telepathy, clairvoyance, precognition, and, more loosely, psychokinesis
- despite considerable research, the existence of any of these modalities remains highly controversial
Extrasensory Perception (ESP)
219
One of the elements of the big five personality model and the five factor personality model, characterized by an orientation of one's interests and energies toward the outer world of people and things rather than the inner world of subjective experience
- It is a broad personality trait and, like introversion, exists on a continuum of attitudes and behaviors
- Extroverts are relatively more outgoing, gregarious, sociable, and openly expressive
Extroversion

The organ of sight
- The human eye has three layers: (a) the outer corneoscleral coat, which includes the transparent cornea and the fibrous sclera; (b) the middle layer, called the uveal tract, which includes the iris, the ciliary body, and the choroid layer; and (c) the innermost layer, the retina, which is sensitive to light
- Retinal ganglion cells within the retina communicate with the central nervous system through the optic nerve, which leaves the retina at the optic disk
- The eye also has three chambers
- The anterior chamber, between the cornea and the iris, and the posterior chamber, between the ciliary body, lens, and posterior aspect of the iris, are filled with a clear, watery fluid, the aqueous humor, and connected by the pupil
- The third chamber, the vitreous body, is the large cavity between the lens and the retina fined with thick, transparent fluid called vitreous humor
Eye
222
A direct look exchanged between two people who are interacting
- Social psychological studies of eye contact generally find that people typically look more at the other person when listening to that person than when they themselves are talking, that they tend to avoid eye contact when they are embarrassed, that women are apt to maintain more eye contact than are men, and that the more intimate the relationship, the greater is the eye contact
Eye Contact
223
A treatment methodology used to reduce the emotional impact of trauma based symptomology associated with anxiety, nightmares, flashbacks, or intrusive thought processes
- The therapy incorporates simultaneous visualization of the traumatic event while concentrating on the rapid lateral movements of a therapist's finger
Eye Movement Desensitization and Reprocessing (EDMR)
224
