Q

History of Intelligence Test

A

It began in a test for children
Intelligence is the ability or mindset to learn a certain thing
The French government wanted to objectively identify slow and fast learners to identify children in need of special education services.
Alfred Binet and Henri Simon (1904): first intelligence test.
When Binet and Simon created the first intelligence test more than a century ago, they had no inkling that they’d alter the landscape of psychology.
Goal is to measure intellectual performance of French school children
Test is a measure of current performance not innate abilities
Mental age vs chronological age
U.S. Impact: Immigrants and military training.

Q

Habituation

A

Familiarity with a stimulus leads to a lessening of response.
As we are exposed to a stimulus repeatedly, our attention to it wanes. We habituate to a stimulus by losing interest in it.

Dishabituation

A

Increased response to new stimulus!
When a stimulus is new to us, our attention is drawn to it. If we have become habituated (bored), and attention is renewed, then we have dishabituated to the new stimulus.

Q

Conditioning

A

Learned associations develop through conditioning process in which environmental stimuli and behavioral responses become connected
1. Classical (Pavlovian) conditioning (巴甫洛夫学说)
learning that events tend to occur together, e.g., thunder and lightning
2. Operant (instrumental) conditioning
learning that a behavior leads to a particular outcome, e.g., put coins in vending machine, retrieve candy; put coins in a slot machine, (maybe) win jackpot

Q

Classical Conditioning

A

Pavlov noticed the dogs salivating as soon as they saw the bowls that usually contained food or when a lab technician walked into the room . This suggested a learned response
Unconditioned stimulus (US): a stimulus that elicits response, such as the reflex without a prior of learning
Unconditioned response (UR): a response that without learning, such as reflex
Neutral stimulus (NS): A stimulus unrelated to UR
Conditioned stimulus (CS): a stimulus that elicits a response only after learning has taken place
Conditioned response (CR): a response to a conditioned stimulus; a response that has been learned
So we can say that Classical conditioning is when a neutral object comes to elicit a response when it is associated with a stimulus that already produces that response

Operant conditioning

A

A learning theory that uses rewards and punishments to reinforce or inhibit behavior, primarily proposed by behavioral psychologist B.F. Skinner. Operant conditioning is different from classical conditioning, which focuses on physiological responses (for example, a bell causing a dog to salivate), while operant conditioning focuses on behavior and its consequences.

Positive:
Give something pleasant after a desirable behavior occurs.
Negative:
Take something unpleasant away
Punishment (Decreasing behavior): Likelihood of behavior occurring again (goes lower)
Positive:
Add something unpleasant following an undesirable behavior
Negative:
Take something pleasant away, e.g. time out.

Q

Four Ways to Shape Behavior

A

Good things Bad (aversive) Thing

Administering Positive reinforcement Positive punishment (spanking)

                       (a reward: money, candy)

Taking away Negative punishment Negative reinforcement
(taking a toy away; time-out) (turning off a shock)

36
Q

Thorndike’s Law of Effect

A

Reinforcement increases the likelihood the behavior will occur in the future
Positive vs. Negative reinforcement
Punishment decreases the likelihood the behavior will occur in the future
Positive vs. Negative punishment
Positive (+) = addition of something
Negative (–) = removal of something

37
Q

Schedules of Reinforcement

A

Giving out rewards for good behavior at certain intervals
Continuous reinforcement schedule
Always given a reward for good behavior
Partial reinforcement schedule
Only sometimes given a reward for good behavior

38
Q

Continuous Reinforcement

A

Reinforcing a behavior every time it occurs
Pro: faster learning
Con: faster extinction

39
Q

Intermittent (Partial) Reinforcement

A

Occasionally reinforcing a behavior
Pro: slower extinction
Con: slower learning

40
Q

Four Reinforcement Schedules

A

Fixed-ratio reinforcement
Given a reward after a certain number of behaviors
Variable-ratio reinforcement
Given a reward after a random number of behaviors
Fixed-interval reinforcement
Given a reward after a certain amount of time has passed
Variable-interval reinforcement
Given a reward after a random amount of time has passed

41
Q

Certain reinforcement schedules can really motivate behavior

A

Continuous reinforcement schedule (reward every time) is what you use to learn a new behavior.
Eventually you move to a partial reinforcement schedule (fixed ratio, variable ratio, fixed interval, or variable interval).
Variable-ratio schedules usually lead to the greatest increase in desired behavior. Better at maintaining behavior for an extended period (e.g., gambling)

42
Q

Shaping

A

To learn to push the cart, the dog was likely
rewarded for behaviors closer and closer to the
desired behavior, known as shaping. Next
time, let’s shape the dog to buy dog food instead of pineapples and eggs, though

43
Q

Observational Learning (recall Bandura)

A

Modeling and imitation
*The Bobo Doll Experiment
* learning aggression through
modeling

44
Q

Cognitive map

A

Cognitive maps are a concept proposed by psychologist Edward Tolman to describe an individual’s internal representation of the external environment in the brain. Cognitive maps help people navigate, remember locations, and make decisions when faced with new situations or routes.

Spatial Representation: Cognitive maps describe the relationships between different locations in space, including distance and direction, allowing individuals to navigate effectively within an environment.

Flexibility: Cognitive maps support not only the memorization of known routes but also adjustments when facing new ones. For instance, if a familiar route is blocked, people can use their cognitive map to find alternative paths.

Accumulation of Experience: Cognitive maps are formed gradually through experience, so as an individual’s experiences grow, their representation of the environment becomes more accurate and detailed.

Abstract Nature: Cognitive maps are mental representations, often presented in an abstract way rather than as precise physical maps. Thus, individuals may remember key places or landmarks rather than every detail.

44
Q

Limit of Bandura’s Social Learning Theory

A

Overemphasis on Observational Learning: SLT places significant emphasis on observational learning, where individuals model others’ behaviors. Critics argue that it downplays other factors like personal motives, innate traits, and biological influences that also contribute to behavior.

Insufficient Attention to Developmental Stages: SLT does not account for age-specific developmental stages. Unlike Piaget’s or Erikson’s theories, it doesn’t explore how observational learning changes with age or cognitive maturity.

Limited Explanation of Internal Processes: While SLT introduces cognitive factors, like attention, retention, and motivation, it primarily focuses on observable behaviors. Critics argue that it overlooks complex internal psychological processes (such as feelings, thoughts, and unconscious motivations) that may affect learning and behavior.

Underestimation of Biological Influences: SLT often overlooks biological and genetic factors that impact behavior. For instance, personality traits, temperament, and other hereditary aspects play a significant role in behavior, which SLT does not fully address.

Challenges in Explaining Complex Behaviors: SLT effectively explains simple behaviors but has limitations in explaining complex behaviors that may not have a direct observational model. For example, it might be less helpful in explaining highly individualistic or original actions that are not based on observed behaviors.

Environmental Determinism: Critics argue that SLT leans towards environmental determinism, implying that individuals are mainly shaped by their surroundings. This downplays the role of personal agency, autonomy, and free will in shaping behavior.

Difficulty in Empirical Measurement: Some components of SLT, like internal cognitive processes (e.g., motivation or attention), are hard to measure empirically. This makes it challenging to test and verify certain aspects of the theory in controlled settings.

45
Q

Implications of Behaviorism

A

Clinical Psychology (CBT)
Child Psychology
Behavior Modification Programs
Health Psychology
Animal Training

46
Q

The science of successful learning

A
  1. Embrace Difficulties : The more effort requires to retrieve the more that learning take place
  2. Avoid illusions of knowing: Familliarity is not mastery. We are drawn to immediate short term gain, not slower, effortful, long term retention.
  3. To learn, retrieve: Periodic practice and testing strengthens retrieve routes. Test your self rather than rereading notes
  4. Space it out , mix it up: When testing youself, variety and a little time to forget, raise the challenge of retreaval and result in greater retention
  5. Beyond learning style: We have different intelligence and by drawing wide variety, we improve retention.
47
Q

How memories stick

A
  1. Increase your ability: Embrace a growth mind set. Practice like an expert and construct memory cues
  2. Elaborate: Find different meaning of new materials by explaining it in your own words and by making connections
  3. Generate: Attempt to answer a question or solve a problem before seeing the solution. Wade into the unknown and puzzle through it
  4. Reflect: Combine elaboration and retrieval b y recalling learning, connecting learning and reflect on the success of learning.
  5. Calibrate: Use objective measures, such as test and expert feedback, to clear away illusions and adjust the accuracy of the judgement of your learning.
48

Proactive
Old Interferes with New

Retroactive
New Interferes with Old

50
Q

Memory illusion

A

It is a false but subjectively compelling memory

Memories are often incomplete, biased, and distorted.

Your memory is not like a video camera, but is a “reconstruction”
Bartlett (1932) had English participants read the Canadian Indian folktale “War of the Ghosts” and recall the story numerous times at varying intervals. At longer intervals, their stories became increasingly distorted; they omitted details and made the story

51
Q

Suggestibility and Child Testimony

A

Young children are especially vulnerable to suggestions to recall events that did not occur
May cling to false memory, even when assured it did not occur
Repeated questioning may elicit misinformation
Especially affected by schemas—organized knowledge structure or mental model that we’ve stored in memory (script memory)

51
Q

Eyewitness Testimony

A

Weak correlation between witnesses’ confidence in their testimony and its accuracy
Less accurate when observing others of different race
Less accurate when the witness has talked to other witnesses
Less accurate when the observed situation is stressful (e.g., threatening, weapon involved)
Many individuals have been wrongly convicted and exonerated through DNA testing

52
Q

Multi-Stage Memory Model

A

Stage 1 :Sensory Encoding
Sensory memory
Short term memory (working memory)
Long term memory

Stage 2: Temporary Storage & Processing

Stage 3: Long-Term Storage & Retrieval
Tip of the tongue Phenomenon:
The experience of knowing that you know something but lack sufficient retrieval cues to access it
Memory in the Brain:
The hippocampus is a brain structure within the limbic system.
It plays an important role in memory consolidation. Memories are not stored directly in the hippocampus, but are distributed

52
Q

Short-term Memory Storage

A

Temporary storage and processing system that retains the information we are currently thinking about for a limited amount of time.
Subject to decay and interference.
Capacity limit: usually people can remember 7 +-2 objects in short term memory. Organizing information to be remembered into meaningful groupings can extend the capacity of short-term memory beyond 7 ± 2.

53
Q

Constructive Nature of Memory

A

Flashbulb memories
Memories of emotional, traumatic events (e.g., assassinations of JFK, MLK, Hurricane Katrina) were thought to be extraordinarily detailed and accurate.
Research has shown that traumatic memories (e.g., the Challenger explosion and 9/11) become distorted over time, just like any other memories.

68
Q

Naturalistic Observation

A

Watching behavior in real world settings
Watching animals in the wild
Observing people in real life settings
Definition
Behavior is observed in the environment in which it occurs naturally.
Advantages
The subject’s behavior is more natural than behaviors taking place in the laboratory.
Disadvantages
The presence of an observer may alter the subject’s behavior.
Low internal validity: the observed behavior may be specific to the individual and the setting, and may not generalize to other individuals in the population or other settings.

69
Q

Case Study

A

Examining one person or a small number of people in depth, often over an extended time period
Definition
Behavior of one person or a few people is studied (in depth).
Advantages
Rich descriptive information.
May help form the research question.
Disadvantages
The case(s) studied may not be representative.
Time-consuming and expensive.
Observer bias.
No conclusion about cause-and-effect.

70
Q

Survey

71
Q

Correlational

A

a research design that examines the effect to which two variables are related or associated.
*“associated” “linked” “related”
Definition
Examines how two or more variables are related
Advantages
May clarify relationships between variables
Disadvantages
If two variables are correlated, it does not mean one variable causes the other. There could be a cause-and-effect relations, but you cannot assume one based on one correlational study

72
Q

Experimental

A

Start with hypothesis
Experimental group
the group(s) that receive the manipulation of the IV
Control group
a comparison group that does not receive the manipulation (or receives one unrelated to the independent variable)
Definition
One or more independent variables are systematically manipulated, and the effect of that manipulation on other dependent variables is studied
Advantages
Offers researchers the opportunity to draw conclusions about cause-and-effect relationships (in contrast to correlational studies!)
High internal validity
Disadvantages
Artificial lab settings and tasks (may compromise external validity)
Confounding variables
Many variables we want to study cannot be manipulated:
age, gender, sexual orientation, marital status, number of children, race/ethnicity, religion, household income, neighborhood characteristics, level of education, employment status, work history, place of birth, immigration status, military service
A TRUE Experiment requires two important things:
Manipulation of the independent variable (and some level of control)
Random assignment of participants to conditions

73
Q

Random Assignment

A

Each research participant has an equal chance of being assigned to any level of the independent variable
Balances out known and unknown factors, increasing the likelihood that the groups are equivalent
Each research participant has an equal chance of being assigned to any level of the independent variable
