Social Facilitation

A

the presence of others will increase the dominant response of a particular behavior (due to increased arousal/nerves)
ex. if you practiced your presentation repeatedly, the presence of others will help you perform, but if you didn’t practice, the presence of others will hinder your performance

Q

Know how to read a hypnogram!

A

Hypnograms track the stages of sleep throughout the night

  • N1 - “relaxed wakefulness”
  • N2 - between N3 and REM
  • N3 - deepest stage/on the bottom of the hypnogram
  • REM - below N1 on the hypnogram

(N1 → N2 → N3 → N2 → REM)

24
Q

Wechsler Scales of Intelligence (WISC)

A

standardization system used to score IQ - scores are “normalized” to a mean of 100 and a standard deviation of 15 (68% of the scores will be b/t 85 and 115)

25
Q

Instinctual Drift

A

phenomenon whereby established habits, learned using operant techniques, eventually are replaced by innate food-related behaviors - so the learned behavior “drifts” to the organism’s species-specific (instinctual) behavior

26
Q

Serial-Position Effect

A

comprised of the primacy and recency effects

27
Q

Hindsight Bias

A

the tendency of individuals to overestimate their ability to have predicted an outcome that could not possibly have been predicted (aka the “knew-it-all-along” phenomenon or “creeping determinism”)

28
Q

Cultural Transmission

A
  • how culture is learned - culture is passed along from generation to generation through various child rearing practices
29
Q

Proximal Stimulus

A

stimulus registered by sensory receptors (e.g., the pattern of light falling on the retina)

30
Q

Flashbulb Memory

A

when people claim to remember every detail of what they were doing when they received news about an emotionally arousing event

31
Q

Motivational State in Operant Conditioning

A

to operationally define a subject’s motivational state, he or she is deprived of some desirable stimulus item for a period of time

32
Q

The Life-Course Approach to Health

A

views health as the product of risk behaviors, protective factors, and environmental agents that we encounter throughout our entire lives and that have cumulative impacts on specific outcomes

33
Q

The Social Construction of Illness

rooted in Social Constructionist Theory

A

individuals and groups produce their own conceptions of reality, and knowledge itself is the product of social dynamics - social constructionists define illness as the social meaning of a biological condition

  1. In social constructionist theory, impairment refers to a physical illness or injury; disability is the social experience of impairment
  2. Illness can reshape an individual’s identity. For example, deafness can be a cultural identity that supplants individual identity
  3. Medicalization - the act of reducing illness to strictly a medical definition/ignores the social context of disease
34
Q

Sensitive/Critical Period

A

point in early development that can have a significant influence on physiological or behavioral functioning in later life - period of time when a child easily absorbs information in a specific way

35
Q

Incentive Theory of Motivation

A

calls attention to how factors outside of individuals, including community values and other aspects of culture, can motivate behavior

36
Q

Drive Theory of Motivation

A

individuals are motivated to take actions in order to reduce internal tension caused by unmet needs - especially useful in explaining behaviors that have a strong biological component, such as hunger or thirst

37
Q

Universally Recognized Emotions

A

there are seven:

  1. Happiness/joy
  2. Sadness
  3. Fear
  4. Surprise
  5. Disgust
  6. Anger
  7. Contempt
38
Q

Neuroleptic Drugs

A

the first antipsychotic drugs used to treat schizophrenia and bipolar disorder - though they are effective in treating positive symptoms, their side effects include cognitive dulling, which can exacerbate negative symptoms

39
Q

General Adaptation Syndrome (GAS)

A

GAS is a model of the body’s stress response that consists of three stages: alarm, resistance, and exhaustion
- individual enters the stage of exhaustion only after that individual has encountered the stressor for a prolonged period of time

40
Q

Activation-Synthesis Theory

A

states that dreams are the result of the cerebral cortex’s attempt to make sense of the neural activity occurring in other parts of the brain during REM sleep (neurobiological explanation)

41
Q

Long-term Potentiation

A

the long-lasting strengthening of synapses between nerve cells that occurs when the synapse of one neuron repeatedly fires and excites another neuron
- used to explain long-term memories (it requires spaced repetition)

42
Q

Parallel Processing

A

the ability of the brain to simultaneously process incoming stimuli of differing quality or from different senses
(ex. allows vision to be divided into components: color, motion, shape, and depth)

43
Q

The Generalized Other - George Herbert Mead

A

individuals react to the expectations of others through their behavior and social interactions - orienting themselves to the norms and values of their community/group

44
Q

Sanctions

A

can either be positive ( rewards ) or negative (punishments)

45
Q

Elements of the McDonaldization of Society

A
  • efficiency
  • calculability, uniformity
  • technological control
46
Q

Which of the following wouldn’t be processed without conscious effort?

a) information about space
b) time
c) frequency of events
d) novel information

A

d) NOVEL INFORMATION requires conscious effort
- due to the brain’s capacity for parallel processing, information about space, time and frequency of events is automatically processed

47
Q

What term describes the relationship between two variables where as one variable increases, so does the other variable, but only up to a certain point, after which, as one variable continues to increase, the other decreases?

A

curvelinear relationship

48
Q

Functional vs. Structural Psychology
- early schools of thought which both contributed to the development of modern psychology ( behaviorism, psychoanalysis, humanism, and cognitive psychology)

A

structuralism: the way to learn about the brain and its functions is to break the mind down into its most basic elements; understanding consciousness through introspection
functionalism: focuses on the purpose of consciousness and behavior - considers them as active adaptations to a person’s environment (evolution played a part in shaping human behavior and the concept of self)

49
Q

Interposition

A

A monocular cue!
When one object obscures another, we only see part of what we expect, so we interpret the object that is partially covered as being further away

50
Q

Place Theory

A

A theory of hearing!
Our perception of pitch depends on the location of the hair cell being vibrated along the basilar membrane
Therefore, the cochlea is organized tonotopically: which hair cells are vibrating gives brain indication of pitch of sound

51
Q

Structural Functionalism

A

sees society as a complex system whose parts work together to promote stability/society functions the way it does by emphasizing on the relationships between the various social institutions (e.g., government, law, education, religion, etc)

52
Q

Thomas Theorem

A

“the interpretation of a situation causes the action”/
“if a person perceives a situation as real, it is real in its consequences”
- Our behavior depends not on the objective reality of a situation but on our subjective interpretation of reality

53
Q

Hawthorne Effect

A

a type of reactivity in which individuals modify an aspect of their behavior in response to their awareness of being observed
(can introduce error into a study)

54
Q

Social Constructionism

A

observes how the interactions of individuals with their society and the world around them gives meaning to otherwise worthless things

55
Q

Accommodation (psychology)

A

new information or experiences cause you to modify your existing schemas

56
Q

Charles Cooley - Looking Glass Self

A

our view of ourselves is influenced by what we imagine others’ opinions to be
(everyone that we interact with in our entire lifespan can influence our self-identity in some way)

57
Q

G. H. Mead - the I and the ME

A
  1. prepatory stage - very young children only imitate/respond
  2. play stage - children become more aware of social relationships, pretend to take roles/create
  3. game stage - the Generalized Other, multiple roles
    (contrast to Cooley’s Looking Glass Self, we are only influenced by some people at certain stages of our life)
  • I: our response to the ME, the decision that we end up making, the less socialized/individual consideration aspect of the self
  • ME: “the social self,” how we believe the Generalized Other sees us, the conforming to society aspect of the self
