PSYC 111 Quiz 2: Review Sheet & Practice

Problems

Quiz: Monday , October 19, in class (multiple choice + free response). Covers everything

after Quiz 1 through the October 14 class: ethics, stress, coping, development,

intelligence, plus the Jamieson et al. (2013) and W oolley et al. (2015) readings.

Note: the October 14 lecture (Intelligence 2) wasn't in the files I received, so intelligence

testing material is not covered here. Send those slides and I'll add them.

Instructor hints from the review sheet:

Y ou won't be asked to name researchers unless you were told to in class (Bowlby,

Kohlberg, Piaget, Vygotsky). Questions describe the idea instead.

For every study , be able to say 1-2 sentences on the method (what did participants

see/do, what was measured), the result, and the conclusion.

Use the overview and summary slides at the start and end of each lecture to find the

main points.

P ART 1: REVIEW SHEET

1. Research Ethics

Guiding question: What do we need to keep in mind to conduct psychology research

ethically?

Vulnerable populations: children, individuals with varying abilities, disadvantaged

groups need extra protection.

Informed consent: tells potential participants about the study and allows them to

agree to participate.

Risk: minimal risk = risk normally associated with everyday activities.

Cost-benefit analysis: the risks to participants are weighed against the potential

benefits of the research.

IRB (Institutional Review Board): reviews proposals for research with human

participants.

IACUC (Institutional Animal Care and Use Committee): reviews proposals for

research with non-human animals.

Page 1 of 18PSYC 111 Quiz 2 Review Sheet & Practice Problems

Class discussion (Little Albert vs. the Office clip): age of the participant, whether

informed + consent is enough, whether any harm can be completely ruled out, and

when pranks/deception are acceptable.

2. Stress

Definition: a process by which an individual perceives and responds to events seen as

overwhelming or threatening. The events are called stressors.

General Adaptation Syndrome (GAS), Selye, 3 stages:

1. Alarm: fight-or-flight response.

HPA axis: hypothalamus receives signals of fear β†’ sympathetic nervous system

activates the adrenal gland β†’ releases epinephrine (adrenaline) and

norepinephrine β†’ body readies for fight or flight. Hypothalamus and pituitary also

orchestrate the adrenal gland's release of cortisol, which floods the body with

energy .

Body effects: pupils dilate, heart beats f aster and harder , quick deep breathing,

muscles tense, blood pressure rises, digestion slows (less saliva, fewer digestive

enzymes, slower bowel movement), skin chills/sweating.

2. Resistance: body adapts to the stressor or finds ways to cope. If the stress continues...

3. Exhaustion: resistance breaks down. Short-term stress responses help us fight

stressors, but chronic stress can lead to physical depletion.

How we study stress: the transactional view (stress as a process; looks at stressors and

how people interpret and cope with them):

Primary appraisal: Is this event harmful?

Secondary appraisal: How well can I cope?

3. Coping

Social support: the soothing impact of friends, f amily , and acquaintances.

Berkman & Syme (1979): longitudinal study of Alameda County residents. Method:

measured people's social connections, then tracked them over 9 years. Result: people

with fewer social connections were more likely to die during follow-up (for both men

and women). Conclusion: social ties are linked to better health and survival.

Gaining control:

Page 2 of 18PSYC 111 Quiz 2 Review Sheet & Practice Problems

Problem-focused coping: attempt to manage or alter the stressor (e.g., applying for

new jobs after being fired).

Emotion-focused coping: change or reduce the negative emotions tied to the stressor

(e.g., mentally restructuring how you think about it).

Informational control: acquire information about the stressor (e.g., learning what a

surgery involves).

Proactive coping: preparing ahead of time for potential stressors.

Individual differences in coping:

Optimism: focusing on the positive side; associated with productivity and health.

Hardiness: a set of attitudes: a sense of control, commitment, and

courage/motivation; associated with health.

Challenge = potential for gain or growth. Eustress = stress associated with positive

feelings and optimal performance (" good stress").

4. Reading: Jamieson, Mendes & Nock (2013), Arousal Reappraisal

Big idea: physiological arousal during stress isn't necessarily bad. T elling people to view

arousal as a tool that helps performance shifts them from a threat state to a challenge

state.

Biopsychosocial model of challenge and threat:

Challenge: perceived resources exceed demands. P attern: improved cardiac

efficiency and dilated blood vessels.

Threat: perceived demands exceed resources. P attern: decreased cardiac

efficiency and constricted blood vessels.

Both involve sympathetic activation, so arousal itself isn't the difference. The

appraisal is.

Arousal reappraisal does not eliminate or dampen arousal. It changes the type of

stress response.

Trier Social Stress T est study (public speaking): 3 groups: reappraisal, placebo (ignore

the stress), no instruction. Reappraisal group: less vasoconstriction, greater cardiac

output (approach-oriented profile), less vigilance for threat cues (emotional Stroop),

and f aster return to baseline after stress.

Page 3 of 18PSYC 111 Quiz 2 Review Sheet & Practice Problems

GRE study (Jamieson et al., 2010): students planning to take the GRE were randomly

assigned to be told that arousal signs predict better performance, or to a control

group. Reappraisal group: higher alpha amylase (sympathetic activation) and better

quantitative scores on the practice GRE and the real GRE 1-3 months later; they also

reported arousal had helped. Verbal scores were unaffected.

Classroom study (Jamieson et al., 2016): double-blind field experiment with

community college developmental math students, reappraisal vs. placebo before Exam

2. Reappraisal group: more coping resources, less math evaluation anxiety , better Exam

2 performance, marginally higher final grades; no effect on course retention.

Limits / moderators: needs motivation (stakes must be high); helps with active-

processing tasks (quant but not verbal). Mechanisms are not fully known.

Applications: cognitive behavioral therapy (CBT), social anxiety disorder , health

education/prevention.

5. Developmental Research Considerations

Post hoc fallacy: assuming that because B came after A, A caused B.

Bidirectional influences: child and environment/caregiver influence each other .

Cross-sectional design: compare different age groups at one time. W eakness: cohort

effects (groups differ because of when they grew up, not age).

Longitudinal design: follow the same people over time. W eakness: attrition

(participants drop out).

Three core differences across theories: stage-like vs. continuous change; domain-

general vs. domain-specific; nature vs. nurture.

6. Cognitive Development Theories

Piaget (children as active learners)

Assimilation: absorbing new experiences into current knowledge structures (calling a

TV car a "truck" because you know trucks).

Accommodation: altering a belief/schema to fit experience (revising "all red go-carts

are f ast" after driving a slow one).

Equilibration: maintaining balance between experience and understanding.

Theory is stage-like, domain-general, and involves nature AND nurture.

Stage Age Key features

Sensorimotor Birth-2 Reflexes; lack object permanence (through ~8

months)

Preoperational ~2-7 Symbolic representation; rigid thinking; lack of

conservation

Concrete operational ~7-11 More logical, flexible, organized; mastery of spatial

operations; difficulty with abstract reasoning

Formal operational ~11+ Abstract and scientific reasoning; internal

reflection

Conservation: changing the appearance of objects does not change their key

properties (e.g., volume).

Influence: learning is an active process; proposes general cognitive processes.

Criticisms: development is more continuous than stage-like; tasks were too

demanding (underestimates children).

Kohlberg (moral reasoning)

Uses moral dilemmas (the Heinz dilemma: law vs. human need). What matters is the

reasoning, not whether Heinz should steal.

Level 1 Preconventional (externally controlled): Stage 1 punishment and obedience

(avoid punishment); Stage 2 instrumental and exchange (satisfy own needs,

"is it worth

the risk?").

Level 2 Conventional (maintain social order): Stage 3 mutual interpersonal

expectations (" good girl/nice boy ,

" win approval); Stage 4 social system and conscience

(laws matter , duty to uphold them).

Level 3 Postconventional (abstract principles): Stage 5 social contract (laws are

flexible; follow when consistent with human rights); Stage 6 universal ethical principles

(self-chosen principles, e.g., preservation of human life).

Evaluation: few people reach the higher stages; associated with level of education;

domain specificity issues; doesn't reflect everyday moral behavior.

Vygotsky (sociocultural theory)

Emphasizes social and cultural factors and social interaction.

Page 5 of 18PSYC 111 Quiz 2 Review Sheet & Practice Problems

Zone of proximal development (ZPD) and scaffolding: a more skilled partner provides

support just beyond what the child can do alone, then withdraws it as skill grows.

Evaluation: helps explain cultural variations, but does not address biological

contributions.

7. Prenatal, Motor, and Social Development

Prenatal stages:

Germinal (conception to ~week 2): ends with attachment to the uterine wall.

Embryonic (~week 2 to 8): begins at attachment, ends with formation of bone cells.

Most major organs form, so this is the period of greatest vulnerability to major

abnormalities.

Fetal (~week 8 to ~38): from bone cells to birth.

T eratogen: an environmental agent that causes harm during the prenatal period.

Critical period: a window when a body part/system is especially vulnerable.

Birth: average length ~20 inches, average weight ~7.5 pounds.

Motor development:

Reflexes: inborn, automatic responses to particular stimuli: swallowing, sucking,

rooting, grasping, stepping, Babinski, Moro.

Milestones (average ages): sitting without support ~6 mo, crawling ~9 mo, standing ~11

mo, cruising ~12 mo, walking without help ~13 mo, running ~18-24 mo.

Variability! The ages are averages, and healthy babies differ a lot in when they hit

milestones.

Social development: attachment:

Attachment: an enduring bond with others; inf ants form attachments to caregivers.

Harlow & Zimmerman: inf ant rhesus monkeys in a cage with two surrogate "moms.

"

Result: feeding is not the only basis for attachment. Comfort/contact matters too.

Bowlby's ethological theory: ethology = the adaptive functions of behavior;

attachment helps inf ants survive. (Bowlby also drew on psychoanalysis.)

Strange Situation procedure: a series of separations and reunions with the caregiver;

researchers watch how the baby reacts. Four classifications:

Secure: upset when caregiver leaves, seeks contact and is easily comforted on

return; uses caregiver as a safe base.

Page 6 of 18PSYC 111 Quiz 2 Review Sheet & Practice Problems

Insecure-avoidant: little distress at separation; ignores or avoids the caregiver on

return.

Insecure-resistant: very distressed at separation; wants contact on return but also

resists it (angry/clingy), hard to soothe.

Disorganized: confused or contradictory behavior (e.g., approaches then freezes).

Correlates of secure attachment: quality of care, especially caregiver sensitivity.

Benefits of secure attachment: better conflict management, less aggression, more

empathy and prosocial behavior , better social competence/peer relations.

8. Intelligence

What is intelligence? Ability to learn from experience, solve problems, and adapt to

new situations.

General intelligence (g): a single f actor that predicts performance across many

different mental tasks.

Fluid vs. crystallized: fluid = reasoning and solving novel problems; crystallized =

accumulated knowledge and skills (vocabulary , f acts).

Sternberg's triarchic theory:

Analytical: analyze, evaluate, judge, compare, contrast ("book smarts").

Creative: produce new ideas/products, novel solutions.

Practical: apply knowledge to real-world, everyday problems ("street smarts").

Gardner's multiple intelligences: intelligence is a set of separate abilities (e.g.,

linguistic, logical-mathematical, spatial, musical, bodily-kinesthetic, interpersonal,

intrapersonal, naturalist). Check your textbook figure for the full list.

Behavioral genetic designs:

Family studies: how traits run in f amilies; similarity declines with biological

distance.

Twin studies: correlations are higher for identical (MZ) than fraternal (DZ) twins β†’

evidence for genetic influence.

Adoption studies: compare people raised apart from biological relatives; show

evidence for both genetic and environmental contributions.

Environmental influences: poverty (negative) and early intervention (positive).

9. Reading: W oolley, Aggarwal & Malone (2015), Collective

Intelligence

Collective intelligence (c): the ability of a group to perform well across a wide variety

of tasks; analogous to g in individuals.

Method: groups of 2-5 people spent ~5 hours doing varied tasks (brainstorming,

verbal/math puzzles, negotiation, moral reasoning). F actor analysis found one

dominant factor explaining 43% of variance in group performance (similar to the 30-

50% for individual intelligence).

c predicts performance on harder criterion tasks (checkers against a computer ,

architectural design) better than average individual intelligence (at least twice as

much variance). A verage/max member IQ correlated with c only moderately . Smart

people alone don't make a smart group.

Bottom-up predictors (group composition):

Average social perceptiveness of members (Reading the Mind in the Eyes test):

the strongest.

Proportion of women: significant, but largely explained by women's higher average

social perceptiveness.

Cognitive-style diversity: inverted U-shape. Moderate diversity is best; too similar

or too different hurts.

T op-down predictors (interaction): groups that communicate more and participate

more equally (turn-taking) are more collectively intelligent.

Did NOT predict c: group satisf action, social cohesiveness, psychological safety .

Replicated online (text chat) and across cultures. c predicted team learning over time

(MBA teams) and performance in a tacit coordination game.

T akeaway: unlike individual intelligence, it may be possible to increase a group's

collective intelligence.
