TEST 1 (UNITS 1 - 4) Flashcards
scientific study of behaviour and mental processes
PSYCHOLOGY
4 goals of psychology:
- description
- explanation
- prediction
- influence
WHICH GOAL OF PSYCHOLOGY?
- usually the first step in understanding any behaviour or mental process
- through making accurate notes about the behaviours or situations we observe
- goal: is usually more important in very new area of research or in early stages of research
DESCRIPTION
WHICH GOAL OF PSYCHOLOGY?
- requires an understanding of the conditions under which a given behaviour or mental process occurs
- researchers try to understand the causes
- allows researchers to tell ‘why’ a given event or behaviour occurred
EXPLANATION
WHICH GOAL OF PSYCHOLOGY?
goal is to understand or predict the likelihood that an event will occur under a certain set of circumstances
PREDICTION
WHICH GOAL OF PSYCHOLOGY?
- accomplished when researchers know how to apply a principle or change a condition to prevent unwanted occurrences or bring about desired outcomes
- enables psychologists to design types of therapy to prevent anxiety attacks or depression
- enables researchers to develop techniques to improve memory
INFLUENCE
WHICH RESEARCH METHOD?
- researcher observes and records behaviour in its natural setting
- participants may or may not know they are being observed
NATURALISTIC OBSERVATION
WHICH RESEARCH METHOD?
- observation under more controlled conditions where sophisticated equipment can be used to measure responses
LABORATORY OBSERVATION
WHICH RESEARCH METHOD?
- in-depth study of one or a few participants using observations, interviews, psychological testing
CASE STUDY
WHICH RESEARCH METHOD?
- interviews and/or questionnaires used to gather information about attitudes, beliefs, experiences, or behaviours of a group of people
SURVEY
WHICH RESEARCH METHOD?
- method used to determine the relationship between two events, characteristics or behaviours
EXPERIMENTAL METHOD
WHICH RESEARCH METHOD?
- random assignment of participants to groups
- manipulation of independent variables and measurement of their effects on the dependent variable
CORRELATION METHOD
WHICH RESEARCH METHOD?
tests used for measuring intelligence, scholastic achievement, aptitudes, vocational interests, personality traits, psychiatric problems
PSYCHOLOGICAL TESTS
INDEPENDENT VARIABLE VS. DEPENDENT VARIABLES?
- variable (for example a factor or condition) that the researcher manipulates in order to determine whether they cause a change in another behaviour or condition.
- sometimes referred to as the treatment
INDEPENDENT
Participants are assigned to take math tests in either a warm classroom or a cold classroom. Tests scores are then examined to determine whether these conditions affected performance. In this example, the independent variable is:
a) mathematical skill
b) test score
c) classroom temperature.
d) not identified
c) classroom temperature.
INDEPENDENT VARIABLE VS. DEPENDENT VARIABLES
measured at the end of the experiment
DEPENDENT
Dependent variable is to __________ as independent variable is to _____________
effect, cause
EXPLAIN WHY PSYCHOLOGICAL TESTS ARE IMPORTANT IN ASSESSING THE PARTICIPANT (CLIENT)
tests provide information that can be used in educational decision making, personnel selection and vocational guidance
RELIABILITY VS. VALIDITY: refers to the consistency of a test
reliability
RELIABILITY VS. VALIDITY: refers to the ability of a test to measure what it is supposed to measure
validity
WHO?
- generally thought of as at the founder of psychology
- considered the subject matter of psychology to be experience
- was searching for the structure of the conscious experience.
WUNDT
SCHOOL OF PSYCHOLOGY:
- proposed by: Wundt’s student Edward Bradfort Titchener
- aim: analyzing the basic elements or the structure of conscious mental experience
- criticized for it’s primary method - introspection - because it was not objective
STRUCTURALISM
SCHOOL OF PSYCHOLOGY:
- concerned with how mental processes help humans and animals adapt to their environment’s
- developed as reaction against structuralism
- broadened the scope of psychology to include the study of behaviour as well as mental processes.
FUNCTIONALISM
SCHOOL OF PSYCHOLOGY:
views observable, measurable behaviour as the appropriate way subject matter for psychology and emphasizes the role of environment as a determinant of behaviour
- John B. Watson
BEHAVIOURISM
SCHOOL OF PSYCHOLOGY:
* developed by Sigmund Freud
* the unconscious is the primary focus
• views human mental life like an iceberg
PSYCHOANALYSIS
WHY DID FREUD VIEW THE SUBCONSCIOUS AS AN ICEBERG?
- the smallest, visible part of the iceberg represents the conscious mental experience of the individual
* underwater, hidden from view, floats a vast store of unconscious impulses, thoughts, wishes and desires
WHICH CURRENT PERSPECTIVES IN PSYCHOLOGY: the importance of the individual’s subjective experience as a key to understanding behaviour
HUMANISTIC
WHICH CURRENT PERSPECTIVES IN PSYCHOLOGY: the role of biological processes and structures, as well as heredity, in explaining behaviour
- study the structures of the brain and central nervous system, the functioning of the neurons, delicate balance of neurotransmitters and hormones, and the impact of genes
BIOLOGICAL
WHICH CURRENT PERSPECTIVES IN PSYCHOLOGY:
- the effect of society and future on behaviour
- seek to understand the cultural context for events
SOCIOCULTURAL
WHICH CURRENT PERSPECTIVES IN PSYCHOLOGY:
- the importance of mental processes – perception, thinking, and memory – that underlie behaviour
- see humans not as passive recipients who are pushed and pulled by environmental forces, but as active participants who seek out experiences, alter and shape them and use mental processes to transform information in the course of their own cognitive development
COGNITIVE
WHICH CURRENT PERSPECTIVES IN PSYCHOLOGY: the role of inherited tendencies that have proven adaptive in humans; studies how inherited tendencies and dispositions in humans influence a wide range of behaviours
EVOLUTIONARY
MAJOR NEUROTRANSMITTER: Plays a role in learning, attention and movement
DOPAMINE
MAJOR NEUROTRANSMITTER: An amino acid that is the main inhibitory neurotransmitter in the brain
GABA
MAJOR NEUROTRANSMITTER: May produce either excitatory or inhibitory effects; affects movement, learning, memory and REM sleep
ACETYLCHOLINE
MAJOR NEUROTRANSMITTER: Provides relief from pain and produces feelings of pleasure and well-being
ENDORPHINS
MAJOR NEUROTRANSMITTER: Produces inhibitory effects at most of the receptors with which it forms synapses; it plays an important role in regulating mood, sleep, impassivity, aggression and appetite
SERATONIN
MAJOR NEUROTRANSMITTER: Affects eating habits, sleep, female sexual behaviour, and it plays a major role in alertness and wakefulness
NOREPINEPHRINE
An important class of neurotransmitters that includes 4 neurotransmitters - dopamine, norepinephrine, epinephrine, and seratonin
MONOAMINES
2 PARTS OF NERVOUS SYSTEM
- central nervous system
2. peripheral nervous system
2 PARTS OF THE CNS:
- brain
2. spinal cord
WHAT DOES THE PNS CONSIST OF?
all the nerves that connect the central nervous system to the rest of the body
2 subdivisions of the peripheral nervous system
- somatic nervous system
2. autonomic nervous system
sympathetic nervous system AND parasympathetic nervous system BELONG TO WHICH PART OF THE NERVOUS SYSTEM?
PNS: AUTONOMIC
- Controls the pituitary gland and regulates hunger, thirst, sexual behaviour, body temperature, and a wide variety of emotional behaviours
- The psychological changes in the body that accompany strong emotion (eg. sweaty palms, pounding heart, lump in throat) are initiated by neurons concentrated mainly in this structure
HYPOTHALAMUS
- It transmits messages between the brain and the peripheral nervous system
- Literally links the body with the brain
SPINAL CORD
Handles functions that are vital to our physical survival and damage to it is life-threatening
BRAIN STEM
- The relay station for virtually all the information that flows into and out of the higher brain centres
- Affects our ability to learn new information, especially if it’s verbal
THALAMUS
- Plays a crucial role in arousal and attention, and screens sensory messages entering the brain
RETICULAR FORMATION
- Its main functions are to execute smooth, skilled movements and to regulate muscle tone and posture
- It has been found to play a role in motor learning and retaining memories of motor activities
CEREBELLUM
- the part of the brainstem that controls heartbeat, breathing, blood pressure, coughing and swallowing
MEDULLA
3 MAJOR STRUCTURES OF THE BRAIN
- LIMBIC SYSTEM
- AMYGDALA
- HIPPOCAMPUS
WHICH MAJOR STRUCTURES OF THE BRAIN? a group of structures in the brain, including the amygdala and hippocampus, that are collectively involved in emotion, memory and motivation
LIMBIC SYSTEM
WHICH MAJOR STRUCTURES OF THE BRAIN? a structure in the limbic system that plays an important role in emotion, particularly in response to aversive stimuli
AMYGDALA
WHICH MAJOR STRUCTURES OF THE BRAIN? a structure in the limbic system that plays a central role in the formation of long-term memories
HIPPOCAMPUS
The lobes that control voluntary movements, speech production and such functioning as tinting, motivation, planning for the future, impulse control and emotional responses
FRONTAL LOBES
The lobes that contain the primary auditory cortex, Wernicke’s area, and association areas for interpreting auditory information
TEMPORAL LOBES
The lobes that contain the somatosensory cortex (where touch, pressure, temperature and pain register) and other areas that are responsible for body awareness and spatial orientation
PARIETAL LOBES
The lobes that contain the primary visual cortex, where vision registers and association areas involved in the interpretation of visual information
OCCIPITAL LOBES
The hemisphere that controls the right side of the body, coordinates, complex movements, and (in 95% of people) controls the production of speech and written language
LEFT
The hemisphere that controls the left side of the body and that, in most people, is specialized for visual-spatial perception and for understanding non-verbal behaviour
RIGHT
WHICH GLAND? located in the brain and often called the “master gland” because it releases the hormones that ‘turn on’ or activate other glands in the endocrine system
- produces the hormone that is responsible for body growth
PITUITARY
WHICH GLAND?
* regulates the body’s blood sugar levels by releasing the hormones insulin glucagon into the bloodstream
- produces digestive enzymes
PANCREAS
WHICH GLAND? Release sex hormones that are responsible for the secondary sex characteristics - pubic and underarm hair in both sexes, breasts in females, and facial hair and a deepened voice in males.
* The ovaries in females and testes in males
GONADS
WHICH GLAND? produce epinephrine and norepinephrine that activate the sympathetic nervous system
- releases the corticoids, which control the body’s salt balance, and also releases small amounts of sex hormones
ADRENAL GLAND
WHICH GLAND? produces the important hormone thyroxin that regulates the rate at which food is metabolized or transformed into energy
THYROID GLAND
______________ furnishes the raw material of sensory experience; _____________ provides the finished product.
SENSATION, PERCEPTION
process by which the senses detect visual, auditory, and other sensory stimuli and transmit them to the brain.
SENSATION
process by which sensory information is actively organized and interpreted by the brain.
PERCEPTION
- Answers the question: “Do we or don’t we sense it?”
* The minimum amount of sensory stimulation that can be detected 50% of the time
ABSOLUTE THRESHOLD
- The smallest increase or decrease in a physical stimulus required to produce a difference in sensation that is noticeable 50% of the time
- This threshold for various senses is not the same for all people
DIFFERENCE THRESHOLD
The view that detection of a sensory stimulus involves both discriminating a stimulus from background ‘noise’ and deciding whether the stimulus is actually present
signal detection theory
- Specialized cells in each sense organ that detect and respond to stimuli - light, sound, odour, etc. - and transducer (convert) the stimuli into neutral impulses.
- These provide the essential links between the physical sensory world and the brain
SENSORY RECEPTORS
- The process by which sensory receptors convert sensory stimulation - light, sound, odours, etc. - into neural impulses
