H Flashcards
The process of enhancing the independence, wellbeing, and level of functioning of an individual with a disability or disorder by providing appropriate resources, such as treatment or training, to enable that person to develop skills and abilities he or she had not had the opportunity to acquire previously
Habilitation
A well learned behavior that is relatively situation specific and over time has become motorically reflexive and independent of motivational or cognitive influence, that is, it is performed with little or no conscious intent
Habit
- The weakening of a response to a stimulus, or the diminished effectiveness of a stimulus, following repeated exposure to the stimulus
- The process of becoming psychologically dependent on the use of a particular drug, such as cocaine, but without the increasing tolerance and physiological dependence that are characteristic of addiction
Habituation
- Any of the sensory receptors for nearing, located in the organ of corti within the cochlea of the inner ear
- They respond to vibrations of the basilar membrane via movement of fine hairlike processes (stereocilia) that protrude from the cells - Any of the sensory receptors for balance, similar in structure to the cochlear hair cells
- They are located in the inner ear within the ampullae of the semicircular canals (forming part of the crista) and within the saccule and utricle (forming part of the macula)
Hair Cell
(Symbol: t1/2)
- In pharmacokinetics, the time necessary for the concentration in the blood of an administered drug to fall by 50%
- Clinically, this varies among individuals as a result of age, disease states, or concurrent administration of other drugs
Half Life
A transitional living arrangement for people, such as individuals recovering from alcohol or substance abuse, who have completed treatment at a hospital or rehabilitation center but still require support to assist them in restructuring their lives
Halfway House
A false sensory perception that has a compelling sense of reality despite the absence of an external stimulus
- It may affect any of the senses, but auditory type and visual type are most common
- This is typically a symptom of a psychotic disorder, particularly schizophrenia, but also may result from substance use, neurological abnormalities, and other conditions
- It is important to distinguish these from illusions, which are misinterpretations of real sensory stimuli
Hallucination
A substance capable of producing a sensory effect (visual, auditory, olfactory, gustatory, or tactile) in the absence of an actual stimulus
- Because they produce alterations in perception, cognition, and mood, these are also called psychedelic drugs (from the Greek, meaning “mind manifesting”)
Hallucinogen
A pathological conditioned characterized by prominent and persistent hallucinations without alterations of consciousness, particularly when due to the direct physiological effects of a substance or associated with neurological factors
Hallucinosis
The tendency for a general evaluation of a person, or an evaluation of a person on a specific dimension, to be used as a basis for judgements of that person on other specific dimensions
- For example, a person who is generally liked might be judged as more intelligent, competent, and honest than a person who is generally disliked
Halo Effect
The consistent use of one hand rather than the other in performing certain tasks
Handedness
Any disadvantage or characteristic that limits or prevents a person from performing various physical, cognitive, or social tasks or from fulfilling particular roles within society
- For example, a nonaccessible building entry or exit for a person in a wheelchair would be considered a handicap, as would the person’s inability to walk
- The term generally is pejorative nowadays and its use was fallen into disfavor
Handicap
Describing a nucleus, cell, or organism that possesses only one representative of each chromosome, as in a sperm or egg cell
- In most organisms, including humans, fusion of these sex cells following fertilization restores the normal diploid condition of body cells, in which the chromosomes occur in pairs
- Hence for humans, this number is 23 chromosomes, that is, half the full complement of 46 chromosomes
Haploid
An emotion of joy, gladness, satisfaction, and wellbeing
Happiness
Relating to the sense of touch or contact and the cutaneous sensory system in general
- It typically refers to active touch, in which the individual intentionally seeks sensory stimulation, moving the limbs to gain information about an object or surface
Haptic
The doctrine that human actions and choices are causally determined by forces and influences over which a person exercises no meaningful influence
- The term can also be applied to nonhuman events, implying that all things must be as they are and could not possibly be otherwise
Hard Determinism
An ability to adapt easily to unexpected changes combined with a sense of purpose in daily life and of personal control over what occurs in one’s life
- This dampens the effects of a stressful situation through information gathering, decisive actions, and learning from the experience
Hardiness
A measure of central tendency
- It is computed for n scores as n/£(1/Xi), that is, n divided by 1/X1 + 1/X2 + …1/Xn
Harmonic Mean
A theoretical approach in programs designed to reduce the adverse effects of risky behaviors (eg; alcohol use, drug use, indiscriminate sexual activity), rather than to eliminate the behaviors altogether
- Programs focused on alcohol use, for example, do not advocate abstinence but attempt instead to teach people to anticipate the hazards of heavy drinking and learn to drink safely
Harm Reduction
The most potent cannabis preparation
- It contains the highest concentration of delta 9 tetrahydrocannabinol (THC) because it consists largely of pure resin from one of the species of the cannabis plant from which it is derived
Hashish
The effect on the behavior of individuals of knowing that they are being observed or are taking part in research
- This is typically positive and is named after the Western Electric Company’s Hawthorne Works plant in Cicero, Illinois, where the phenomenon was first observed during a series of studies on worker productivity conducted from 1924 to 1932
- These Hawthorne studies began as an investigation of the effects of illumination conditions, monetary incentives, and rest breaks on productivity, but evolved into a much wider consideration of the role of worker attitudes, supervisory style, and group dynamics
Hawthorne Effect
A model that identifies the relationships of the following to the likelihood of taking preventative health action: (a) individual perceptions about susceptibility to and seriousness of a disease, (b) sociodemographic variables, (c) environmental cues, and (d) perceptions of the benefits and costs
Health Belief Model
The subfield of psychology that focuses on (a) the examination of the relations between behavioral, cognitive, psychophysiological, and social and environmental factors and the establishment, maintenance, and detriment of health; (b) the integration of psychological and biological research findings in the design of empirically based interventions for the prevention and treatment of illness; and (c) the evaluation of physical and psychological status before, during, and after medical and psychological treatment
Health Psychology
The inability to hear a normal range of tone frequencies, a normally perceived level of sound intensity, or both
Hearing Loss
A junction between neurons that is strengthened when activity in the axon of the presynaptic (transmitting) neuron results in simultaneous activity in the postsynaptic (recieving) neuron
[Donald O. Hebb (1904 - 1985), Canadian psychologist]
Hebbian Synapse
The branch of psychology concerned with the study of pleasant and unpleasant sensations and thoughts, especially in terms of their role in human motivation
Hedonics
- In philosophy, the doctrine that pleasure is an intrinsic good and the proper goal of all human action
- One of the fundamental questions of ethics has been whether pleasure can or should be equated with the good in this way
- In psychology, any theory that suggests that pleasure and the avoidance of pain are the only or the major motivating forces in human behavior
- This is a foundational principle in psychoanalysis, in behaviorism, and even in theories that stress self actualization and need fulfillment behavior that involves one or more individuals acting to improve the status or wellbeing of another or others
- Although typically in response to a small request that involves little individual risk, all helping incurs some cost to the individual providing it
Hedonism
The theory that learned helplessness explains the development of or vulnerability to depression
- According to this theory, people repeatedly exposed to stressful situations beyond their control develop an inability to make decisions or engage effectively in purposeful behavior
Helplessness Theory
Loss of vision in half of the visual field
Hemianopia
Complete paralysis that affects one side of the body
Hemiplegia
Either of the symmetrical halves of the cerebrum or the cerebellum
Hemisphere
Surgical removal of either one of the cerebral hemispheres of the brain
Hemispherectomy
The idea that the two cerebral hemispheres of the brain are not identical but differ in size, shape, and function
- The functions that display the most pronounced asymmetry are language processing in the left hemisphere and visuospatial processing in the right hemisphere
Hemispheric Asymmetry
The processes whereby some functions, such as handedness or language, are controlled or influenced more by one cerebral hemisphere than the other and each hemisphere is specialized for particular ways of working, managing information in a unique fashion and, in some cases, being structurally asymmetrical
- Researchers now prefer to speak of this for particular functions, rather than hemispheric or lateral dominance
Hemispheric Laterialization
Bleeding; any loss of blood from an artery or vein
- This may be external, internal, or within a tissue, such as the skin
Hemorrhage
The view that genetic inheritance is the major influence on behavior
- Opposed to this view is the belief that environment and learning account for the major differences between people
- The question of heredity versus environment or “nature versus nurture” continues to be controversial, especially as it applies to human intelligence
Hereditarianism
The transmission of traits from parents to their offspring
- study of the mechanisms and laws of this is the basis of the science of genetics
- This depends upon the character of the genes contained in the parents’ chromosomes, which in turn depends on the particular genetic code carried by the DNA of which the chromosomes are composed
Heredity
A theory of color vision postulating that there are three sets of receptors, one of which is sensitive to white and black, another to red and green, and the third to yellow and blue
- The breaking down (catabolism) of these substances is supposed to yield one member of these pairs (white, red, or yellow), while the building up (anabolism) of the same substances yields the other (black, green, or blue) [Proposed in 1875 by German physiologist and psychologist Ewald Hering (1834 - 1918)]
Hering Theory of Color Vision
An estimate of the contribution of inheritance to a given trait or function
- These can range from 0, indicating no contribution of these factors, to 1, indicating total contribution of these factors
- The heritability of intelligence is believed to be roughly .5, for example
- This is not the same as genetic contribution, because this is sensitive only to sources of individual differences
- Moreover, a trait can be heritable and yet modifiable
Heritability
Any traditions or other inmaterial attributes passed from preceding to successive generations
- This may be cultural, encompassing the customs, language, values, and skills that help to maintain a particular group’s sense of identity, or social, encompassing learned interpersonal behaviors (eg; shaking hands when greeting others, giving gifts on particular occasions)
Heritage
The condition of possessing both male and female sex organs (in humans, for example, possessing both ovarian and testicular tissue)
- It is very rare and should not be confused with the more common pseudohermaphroditism, in which the gonads are of one sex but the external genitalia are either ambiguous or of the opposite sex
Hermaphroditism
The theory or science of interpretation
- This is concerned with the ways in which humans derive meaning from language or other symbolic expression
- Two main strains of this thought have developed
- In the first, a key concept is the need to gain insight into the mind of the person or people whose expression is the subject of interpretation
- In the second, more radical, strain of hermeneutics, the project of interpretation was expanded to include the human being itself
- This suggests that all human behavior can be understood as meaningful expression, much as one would understand a written text
- This move has given rise to a broad movement within philosophy, psychology, and literary criticism in which richness of interpretation is considered more valuable than consistent methodology or arriving at the “correct” interpretation
- This type has informed other contemporary movements, notably existentialism, postmodernism, and poststructuralism
Hermeneutics
A highly addictive opioid that is synthetic analog of morphine and three times more potent
- Its rapid onset of action leads to an intense initial high, followed by a period of euphoria and a sense of well being
Heroin
(Symbol: Hz)
The unit of frequency equal to one cycle per second [Heinrich Rudolf Hertz (1857 - 1894), German physicist]
Hertz
One of several transverse ridges on the upper side of the temporal lobe of the brain that are associated with the sense of hearing [Richard Heschl (1824 - 1881), Austrian pathologist who first traced the auditory pathways of humans to this convolution]
Heschl’s Gyrus
The situation in which populations or cells in a experimental design have unequal variances
Heterogeneity of Variance
Composed of diverse elements
Heterogenous
In the theory of moral development expounded by Swiss psychologist Jean Piaget (1896 - 1980), the stage at which the child, approximately 6 to 10 years of age, equates morality with the rules and principles of his or her parents and other authority figures
- That is, the child evaluates the rightness or wrongness of an act only in terms of adult sanctions for or against it and of the consequences or possible punishment it may bring
Heteronomous Stage
Any tendency for individuals who differ from one another in some way to make social connections
- It is less common than homophily
Heterophily
The situation in which Var(Y|X) is not the same for all values of X, that is, the variance in Y is a function of the variable X
Heteroscedasticity
Sexual attraction to or activity between members of the opposite sex
Heterosexuality
A strategy for solving a problem or making a decision that provides an efficient means of finding an answer but cannot guarantee a correct outcome
- By contrast, an algorithm guarantees a solution to a problem (if there is one) but may be much less efficient
Heuristic
A theory of persuasion postulating that the validity of a persuasive message can be assessed in two different ways
- Systematic processing involves the careful scrutiny of the merits of attitude relevant information in the message
- Heuristic processing involves the use of a subset of information in the message as a basis for implementing a simple decision rule to determine if the message should be accepted (eg; judging a message to be valid because its source is highly credible)
Heuristic Systematic Model
The phenomenon whereby highly hypnotizable people who are asked to block certain stimuli (eg; pain) can sometimes register the blocked pain or other sensation via hand signals, as if a dissociated observer is simultaneously taking part in events that are disavowed by the dominant observer
- Such individuals can later recall auditory, visual, or tactile stimuli to which they appeared oblivious at the time
Hidden Observer
A clear ordering of phenomena on some dimension, such as a dominance hierarchy
Hierarchy
Any of the more complex types of cognition, such as thinking, judgement, imagination, memory, and language
Higher Mental Process
In Pavlovian conditioning, a procedure in which the conditioned stimulus of one experiment acts as the unconditioned stimulus of another, for the purpose of conditioning a neutral stimulus
- For example, after pairing a tone with food, and establishing the tone as a conditioned stimulus that elicits salivation, a light could be paired with the tone
- If the light alone comes to elicit salivation, then this has occurred
Higher Order Conditioning
In the analysis of variance, the joint effect of three or more independent variables on the dependent variable
Higher Order Interaction
