Q

Define: learned helplessness

A

When an organism (person, animal, etc.) is prevented from avoiding some aversive stimulus repeatedly (e.g., continuous electric shocks) the organism will reach a state in which it becomes passive and depressed because he believes that there are no actions it can take to avoid the aversive stimulus. Esssentially, the organism just gives up trying to avoid it and just takes the aversive stimulus. Thus, the organism learns that it is helpless against the aversive stimulus.

A

Includes eight stages. At each stage there is a different and specific conflict that the individual must resolve in order to move to the next stage of development. If the person is unable to resolve a conflict at a particular stage, they will confront and struggle with it later in life. According to Schultz and Schultz (1987), “The person is faced with a choice between two ways of coping with each crisis, an adaptive or maladaptive way. Only when each crisis is resolved, which involves a change in the personality, does the person have sufficient strength to deal with the next stages of development”. So you see, this theory is based on encountering and resolving conflicts, which helps the person establish a sense of identity and move from one developmental stage to the next.

281
Q

What is the Door-in-the-face technique for persuasion?

A

A technique used to get compliance from others (to get them to behave in a way you want) in which a large request is made knowing it will probably be refused so that the person will agree to a much smaller request. The real objective is to get the person to agree to the small request, which is made to seem very reasonable because it is compared to such a large, seemingly unreasonable request. In essence, the large request gets you the “door in the face” when you ask it. For example, someone might ask you to give to give 5 hours of your time a week for the next year as a volunteer to a charity. After hearing this offer you may think it is a huge request, after which you may be asked to, instead of committing to all this volunteering time, to just donate a small amount of money. Compared to the time commitment, this request seems much more acceptable.

282
Q

What is the drive reduction theory?

A

Drives and needs are present, one aspires to meet needs and drives reduce those needs

283
Q

What is the ego?

A

Helps the individual adapt to external reality by making compromises between the id, the superego, and the environment. Operates by the “reality principle” – directs the individual to express sexual and aggressive impulses in socially acceptable ways.

284
Q

What is the Elaboration Likelihood Model?

A

People are more likely to carefully process persuasive messages when they are motivated and capable of considering all available information. So, if someone watches a political debate with great interest and attention they are more likely to evaluate the candidates and their arguments based on merit and to be more thoughtful about their evaluations. But if they watch a debate on a topic they’re not interested in or they don’t understand, they will evaluate the arguments based on other cues such as the emotional tone of the message or the physical attractiveness of the candidate.

285
Q

What is the evolutionary approach to motivation?

A

Involves the role that instincts play in motivation

286
Q

What is the first stage of Erickson’s theory?

A

Trust vs mistrust
0-1years
Virtue: hope
Outcome: fear, suspicion

287
Q

What is the foot-In-the-door phenomenon?

A

The tendancy for people to comply with some large request after first agreeing to a small request. As you can then imagine, the technique is used to get compliance from others (to get them to behave in a way you want) in which a small request is made first in order to get compliance for a larger request.

288
Q

What is the function of the adrenal cortex?

A

Release cortisol in times of stress and aldosterone in response to low BP or low blood osmolarity

289

Contains innate biological drives, seeks immediate gratification, and operates by the pleasure principle (seeking gratification of impulses).

294
Q

What is the incentive theory?

A

Reward is presented after the occurrence of an action, increases that action

295
Q

What is the Interactionist theory?

A

Language development is both biological and social. Interactionists argue that language learning is influenced by the desire of children to communicate with others. (Mainly via Vygotsky)

296
Q

What is the James-Lange Theory of Emotion?

A

An individual has a physiological response to a stimulus first, and then experiences an emotion based on his or her perception of the physiological response. A person sees a bear and starts trembling, breathing faster, and sweating. The person interprets these physical symptoms as resulting from the emotion “fear,” so he or she consequently feels afraid.

Bear (Event ) => “Fight or Flight” response (physical) => Emotion (Fear)

297

A

A behavior is deviant simply if people have judged behavior and labeled it as deviant

298
Q

What is the Late Selection Theory?

A

All messages get through, but that only one response can be made (late selection)

299
Q

What is the Lazarus Theory of Emotion?

A

A thought must occur before an emotion or physiological response can take place. Therefore, a person sees a bear (event), the person thinks “I am going to be shredded into tiny little pieces” (thought), and the person simultaneously feels fear and prepares for “fight or flight.”

Bear (Event) => “I am going to die” => fear (Emotion) + “Fight or Flight” (Physical)

300
Q

What is the limbic system?

A

A grouping of structures in the brain that sits between in the most primitive part of the forebrain called the rhinecephalon. It is a network of neurons that influences pain, anger, hunger, sex, thirst, and pleasure. The thalamus, hypothalamus, amygdala, fornix, mammiliary bodies, and septal areas are all parts of the limbic system.

301
Q

What is the Low-ball technique for persuasion?

A

A technique used in sales and other styles of persuasion to offer products or services at a bargain price in order to first attract a buyer, but then adds on additional expenses to make the purchase less of a bargain than originally thought. This is the technique often seen in car sales when the salesperson quotes a low price for the basic car, but then tacks on options, extended warranties, service packages, etc. to end in a much higher price tag than was originally quoted.

302

A 
HATH
Hypothalamus
Amygdala
Thalamus
Hippocampus

A

A tendency for the infant, when stroked on the side of the face, to move its face in the direction being stroked, open its mouth, and search for a nipple. This reflex is for survival as it helps infants locate food.

317
Q

What is the Sapir-Whorf hypothesis, aka Whorfianism?

A

The structure of human language effects the way in which an individual conceptualizes their world. Working from the position that every language describes and conceptualizes the world in its own unique way, it holds that a person’s native language limits their cross-cultural understanding.

318
Q

What is the Schachter-Singer Theory of Emotion?

A

Their theory states that a person has a physiological response, thinks or reasons about it, and then has the emotion. I see a bear (event), my heart starts racing and I breath faster (physical response), I think “hmmm… that bear looks upset that I pushed its bear cub around. I probably should have not done that. I might want to consider retreating before I’m fed to the cub for dinner” (thought), and I feel terrified.

Bear (Event) => “Fight or Flight” (Physical) => Bears are protective parents (Reasoning) => Fear (Emotion)

319
Q

What is the second stage in Erickson’s theory?

A

Autonomy vs doubt
1-2 years
Virtue: independence
Outcome: shame, doubt

320

A

Self esteem and self efficacy

322
Q

What is the self fulfilling prophesy?

A

A prediction that causes itself to come true due to the simple fact that the prediction was made. This happens because our beliefs influence our actions.

323
Q

What is the social cognitive theory of personality?

A

Similar to the behavioral perspective, but here cognitive factors important in determining behavior…the environment/learning and cognition are the determining factors in behavior. In addition, there are two important concepts you need to be familiar with:

1) reciprocal determinism – Bandura’s belief that personality traits, environmental factors, and overt behavior don’t determine behavior in isolation. Rather, these factors affect each other to determine our behaviors. Reciprocal determinism also relies on a person’s self-efficacy.
2) self - efficacy – a person’s belief that he or she can perform behaviors that are necessary to produce a desired outcome. Self-efficacy influences what choices we make in different situations, the situations we enter, and the outcomes. For example, do you think a person with low self-efficacy would enter a situation in which they must perform a difficult task in front of a large crowd of people?

324
Q

What is the social identity theory

A

This theory addresses the ways in which people perceive and categorize themselves. According to social identity theory, individuals form self-conceptions that are based on two parts: 1) personal or self identity, and 2) collective identity. Personal or self identity refers to our unique, personal qualities such as our beliefs, our abilities and skills, etc. The collective self includes all the qualities that arise from being part of a society, culture, family, groups, clubs, etc. For example, you may identify yourself as a protestant, male, football player, who is very popular with people at school.

325
Q

What is the Stanford Prison Experiment?

A

A controversial experiment which investigated the psychological effects of being a prisoner or prison guard. In the experiment, college students were randomly assigned to become prisoners or guards.

During the course of the experiment, both the prisoners and guards rapidly internalized their roles (they started to become their roles), with the guards becoming sadistic, and the prisoners becoming passive and depressed. Originally designed as a two-week experiment, the duration was cut short after 6 days due to the emotional trauma experienced by the participants.

The study demonstrated what Zimbardo calls the Lucifer Effect - how good people can turn evil in response to the situation they are in, and not as a result of their real personalities.

326
Q

What is the sucking reflex?

A

Infant sucks when area around mouth is touched

327
Q

What is the superego?

A

A

Analytical intelligence
Creative intelligence
Practical intelligence

329
Q

What is the theory of differential association?

A

330
Q

What is the theory of planned behavior?

331
Q

What is the third stage of Erickson’s theory?

A

Initiative vs guilt
3-5 years
Virtue: purpose
Outcome: inadequacy

332
Q

What is the trichromatic theory?

A

The human retina contains three different receptors for color (meaning each one is most sensitive to one color): one is most sensitive to red, one is most sensitive to green, and one is most sensitive to blue. These color receptors combine the colors to produce the perception of virtually any color. You notice that there are no receptors specific to orange, but by stimulating the right cones in the right way, orange color is produced.

333
Q

What is the Wernicke’s area known to do, and what are symptoms of its damage?

A

Language understanding

Damaged: cannot produce meaningful sentences. Words are real, but whole sentences don’t make sense (Wernicke’s aphasia)

334
Q

What is Universalism?

A

Theory of language-thoughts dictate language that develops. Language is merely a reflection of human thought, and so all languages are significantly similar in their conceptual categories.

335
Q

What is used to study sleep cycles?

A

EEG

336
Q

What is Vygotsky’s idea of Sociocultural Development?

A

The idea that society and culture shape cognition. Social customs, beliefs, values, and language are all part of what shapes a person’s identity and reality. According to this approach, what a person thinks is based on his or her socio-cultural background. A socio-cultural approach takes into account more than the individual in attempting to understand cognitive processes.

337
Q

What is Vygotsky’s theory of language?

A

Language and thought are independent and can be learned to connect

338
Q

What is weak linguistic determinism?

A

Language only weakly influences thought

339
Q

Sensitization

A

An increase in the strength of a response its repeated exposure (increased response with stimulus)

340
Q

What it the Cannon-Bard Theory of Emotion?

A

An emotion is produced when some stimulus triggers the thalamus to send information simultaneously to the brain (specifically, the cerebral cortex) and the autonomic system (including the skeletal muscles). Thus, the stimulus is perceived at both a physiological and the subjective level.

Bear (Event) => Fear (Emotion) => “Fight or Flight” response (physical)

341
Q

What type of motor skills develop first?

A

Gross- larger muscles

342
Q

What type of motor skills develop second?

A

Fine motor skills-smaller muscles

343
Q

What was Lazarus’ stance on stress?

A

Stress stems from appraisal (primary and secondary appraisals)

344
Q

What was the Milgram Experiment?

A

A study that found that a big majority of the participants were willing to obey an authority figure even when they were being instructed to do something that they believed was morally wrong.

The study was composed of an experimenter, a learner (who was an accomplice), and a teacher (the participant). The “teacher” was instructed by the experimenter to deliver increasingly stronger electric shocks whenever the learner gave a wrong response. After several wrong answers and voltage increases, the “learner” would start to bang on the wall that separated him from the “teacher”, scream, and generally make it clear that he was in pain. After several more shocks, the learner ceased responding.

Milgrim found that, even though most participants didn’t want to continue delivering the shocks, they would do it as long as the researcher kept telling them to do so.

Milgram concluded that people’s obedience may be explained by the Agentic State Theory, which states that people see themselves as mere instruments for implementing the wishes of a higher authority, and can therefore not be held liable for their actions, since they are “just doing their job.” Milgram believed that this explains how soldiers were able to act as they did during the Holocaust.
