Q

Why Study Psych?

A
  • To understand ourselves
  • To understand other people and groups
  • To be better able to influence others, for example, in socializing children or motivating employees
  • To learn how to help others better and improve the world, for example, by doing effective psychotherapy
  • To learn a skill that will lead to a profession such as being a social worker or a professor
  • To learn how to evaluate the research claims you hear or read about
    Because it is interesting, challenging, and fun!
    People want to learn about psychology because this is exciting in itself, regardless of other positive outcomes it might have.
    Why do we see movies? Because they are fun and exciting, and we need no other reason.
    Thus, one good reason to study psychology is that it can be rewarding in itself.

Define conditioned stimulus

A

An initially neutral stimulus (like a bell, light, or tone) that elicits a conditioned response after it has been associated with an unconditioned stimulus.

142
Q

Define unconditioned stimulus

A

In classical conditioning, the stimulus that elicits the response before conditioning occurs.

143
Q

Define conditioned response

A

The response that is elicited by the conditioned stimulus after classical conditioning has taken place.

144
Q

Define unconditioned response

A

In classical conditioning, an innate response that is elicited by a stimulus before (or in the absence of) conditioning.

145
Q

instrumental / operant conditioning

A

Describes stimulus-response associative learning.

146
Q

operant behaviour

A

A behavior that is controlled by its consequences. The simplest example is the rat’s lever-pressing, which is controlled by the presentation of the reinforcer.
punishment and reinforcement

147
Q

Define reinforcer

A

Any consequence of a behavior that strengthens the behavior or increases the likelihood that it will be performed it again.

148
Q

Define punisher

A

A stimulus that decreases the strength of an operant behavior when it is made a consequence of the behavior.

149
Q

What is taste aversion conditioning
(classical)

A

The phenomenon in which a taste is paired with sickness, and this causes the organism to reject—and dislike—that taste in the future.

150
Q

Define fear conditioning
(classical)

A

A type of classical or Pavlovian conditioning in which the conditioned stimulus (CS) is associated with an aversive unconditioned stimulus (US), such as a foot shock. As a consequence of learning, the CS comes to evoke fear. The phenomenon is thought to be involved in the development of anxiety disorders in humans.

151
Q

Define conditioned compensantory response

A

In classical conditioning, a conditioned response that opposes, rather than is the same as, the unconditioned response. It functions to reduce the strength of the unconditioned response. Often seen in conditioning when drugs are used as unconditioned stimuli.

152
Q

What is a prediction error?

A

When the outcome of a conditioning trial is different from that which is predicted by the conditioned stimuli that are present on the trial (i.e., when the US is surprising). Prediction error is necessary to create Pavlovian conditioning (and associative learning generally). As learning occurs over repeated conditioning trials, the conditioned stimulus increasingly predicts the unconditioned stimulus, and prediction error declines. Conditioning works to correct or reduce prediction error.

153
Q

What is preparedness?

A

The idea that an organism’s evolutionary history can make it easy to learn a particular association. Because of preparedness, you are more likely to associate the taste of tequila, and not the circumstances surrounding drinking it, with getting sick. Similarly, humans are more likely to associate images of spiders and snakes than flowers and mushrooms with aversive outcomes like shocks.

154
Q

What is extinction?

A

Decrease in the strength of a learned behavior that occurs when the conditioned stimulus is presented without the unconditioned stimulus (in classical conditioning) or when the behavior is no longer reinforced (in instrumental conditioning). The term describes both the procedure (the US or reinforcer is no longer presented) as well as the result of the procedure (the learned response declines). Behaviors that have been reduced in strength through extinction are said to be “extinguished.”

155
Q

Define spontaneous recovery

A

Recovery of an extinguished response that occurs with the passage of time after extinction. Can occur after extinction in either classical or instrumental conditioning.

156
Q

What is context?

A

Stimuli that are in the background whenever learning occurs. For instance, the Skinner box or room in which learning takes place is the classic example of a context. However, “context” can also be provided by internal stimuli, such as the sensory effects of drugs (e.g., being under the influence of alcohol has stimulus properties that provide a context) and mood states (e.g., being happy or sad). It can also be provided by a specific period in time—the passage of time is sometimes said to change the “temporal context.”

157
Q

Define stimulis control

A

When an operant behavior is controlled by a stimulus that precedes it.

158
Q

Define discrimnatiative stimulis

A

In operant conditioning, a stimulus that signals whether the response will be reinforced. It is said to “set the occasion” for the operant response.

159
Q

Define categorize

A

To sort or arrange different items into classes or categories.

160
Q

What is quantitative law of effect

A

A mathematical rule that states that the effectiveness of a reinforcer at strengthening an operant response depends on the amount of reinforcement earned for all alternative behaviors. A reinforcer is less effective if there is a lot of reinforcement in the environment for other behaviors.

161
Q

REM sleep is most closely associated

A

memory consolidation

162
Q

process sensory receptors respond and convey information to brain

A

sensation

163
Q

What does oxitocen hormone

A

love hormone, cuddle hormone

164
Q

Cortisol hormone does what?

A

stress hormone, weight gain, cravings, decreased response time

165
Q

reinforcer devaluation effect

A

The finding that an animal will stop performing an instrumental response that once led to a reinforcer if the reinforcer is separately made aversive or undesirable.

166
Q

Goal directed behaviour

A

Instrumental behavior that is influenced by the animal’s knowledge of the association between the behavior and its consequence and the current value of the consequence. Sensitive to the reinforcer devaluation effect.

167
Q

habit

A

Instrumental behavior that occurs automatically in the presence of a stimulus and is no longer influenced by the animal’s knowledge of the value of the reinforcer. Insensitive to the reinforcer devaluation effect.

168
Q

who are social models?

A

Authorities that are the targets for observation and who model behaviors.

169
Q

Albert Bandura’s “Bobo doll experiment.”

A

children act like social model

agressive social model = agressive kids

gentle = gentle

170
Q

vicarious reinforcement

A

Learning that occurs by observing the reinforcement or punishment of another person.

171
Q

Aaron has been using heroin at his friend Luca’s apartment. One night Aaron takes the same dose of heroin when he is home alone, and nearly dies from an overdose. Which phenomenon related to classical conditioning explains why this happened?

A

conditioned compensatory response

172
Q

Define knowledge emotions

A

A family of emotions associated with learning, reflecting, and exploring. These emotions come about when unexpected and unfamiliar events happen in the environment. Broadly speaking, they motivate people to explore unfamiliar things, which builds knowledge and expertise over the long run.

173
Q

Define functionalist theories of emotion

A

Theories of emotion that emphasize the adaptive role of an emotion in handling common problems throughout evolutionary history.

174
Q

Define surprise

A

Evaluations that relate what is happening in the environment to people’s values, goals, and beliefs. Appraisal theories of emotion contend that emotions are caused by patterns of appraisals, such as whether an event furthers or hinders a goal and whether an event can be coped with.

175
Q

Define interest

A

An emotion associated with curiosity and intrigue, interest motivates engaging with new things and learning more about them. It is one of the earliest emotions to develop and a resource for intrinsically motivated learning across the life span.

176
Q

What is Intrinsic motivation

A

Learning that is “for its own sake”—such as learning motivated by curiosity and wonder—instead of learning to gain rewards or social approval.

177
Q

Define trait curiosity

A

Stable individual-differences in how easily and how often people become curious.

178
Q

What is openness to experience

A

One of the five major factors of personality, this trait is associated with higher curiosity, creativity, emotional breadth, and open-mindedness. People high in openness to experience are more likely to experience interest and awe.

179
Q

Define confusion

A

An emotion associated with conflicting and contrary information, such as when people appraise an event as unfamiliar and as hard to understand. Confusion motivates people to work through the perplexing information and thus fosters deeper learning.

180
Q

What is impasse driven learning

A

An approach to instruction that motivates active learning by having learners work through perplexing barriers.

181
Q

What is awe?

A

a state of fascination and wonder

182
Q

What is accomodation?

A

Changing one’s beliefs about the world and how it works in light of new experience.

183
Q

What are chills

A

A feeling of goosebumps, usually on the arms, scalp, and neck, that is often experienced during moments of awe.

184
Q

How do emotions promote learning?

A

They then motivate us to engage with the new things that strain our understanding of the world and how it works. Emotions surely aid fighting and fleeing, but for most of the hours of most of our days, they mostly aid in learning, exploring, and reflecting.

185
Q

What does impasse-driven learning entail?

A

confusion is beneficial for learning
