What is Short-Term Memory ?
- Information and input that is currently activated and maintained.
- 7 plus or minus two (or maybe 4 plus or minus 1)
- in general ppl can remember 7 pieces of information (+ or - 1) → why phone numbers used to be 7 digits
- Can not be manipulated
- Rehearsal maintains information
- Have to think about it again and again
- 7 plus or minus two (or maybe 4 plus or minus 1)
What is Working Memory?
- Manipulation and attention to activated information.
- Working towards goals: what do I need this information for? How can I achieve that?
What is Long-Term Memory
- Information from past experience that may or may not be currently activated.
- Is stored in some way
How does information get stored into long-term memory?
- Sensory -> 2. Short term memory -> consolidation -> 3 Long term memory (also by rehearsal)
sensory info → maintained via rehearsal → then consolidated into long term memory and then is capable of people retrieved.
What area of the brain is responsible for short-term and working memory?
PFC (prefrontal cortex)
What area of the brain is responsible for Long-term Memory?
Hippocampus
- particularly the consolidation phases → hippocampus important for passing things into long-term memory
What did HM (Henry Molaison (1926-2008) Show?
- Henry Molaison (1926-2008)
- Resected MTL (Hippocampus)
- Unable to form new memories
- Repetition maintained information
- Lost it after stopping
- Could learn new skills through practice
- Got him to draw in a mirror → became very good at it → but did not remember ever doing it before
- Large pieces of his brain dissected
- Large pieces of the temporal lobe
- Left him in a unique state where he was unable to form new memories
- He could form new information and could form short term memories but could not translate that short-term info into long-term.
How do we remember?
- Memory is a reconstructive process.
- Information retrieval is influenced by biases, schemas, motives and goals.
- Just like perceptions (eg. Where’s Waldo; Gorilla X-Ray; Donald and priming, etc)
- It is easier to remember schema-consistent information.
- Schemas guide the reconstruction
- Information that is highly inconsistent with schemas may be processed more thoroughly.
- Information retrieval is influenced by biases, schemas, motives and goals.
How do Current Schemas Affect Current Views of Past Events?
-
Mood-congruent memory: People are more likely to remember positive information when in a positive mood and negative
information when in a negative mood.- General rosy recollection bias
-
Application: Taking a test? Bring some things that activate the same schema and mood
- Songs, coffee, same pencil…
What is The Misinformation Effect?
- The process by which cues that are given after an event can plant false information into memory.
- Loftus and her colleagues (1978) illustrated how the phrasing of a question can lead someone to remember seeing something, like broken glass, that actually wasn’t there.
What was the Misinformation Effect Car Crash Study (Cohen) and what did it exhibit?
- Two ppl watching the same video, in video they both see a car wreck.
- First person asked how fast the car was going when it hit other car
- Second person asked how fast the car was going when it smashed into the other car
- In a follow-up question, when asked if there was broken glass
- No from ‘hit’
- Yes from ‘smashed’
- Cohen, 1981 study on how schemas shape memory: participants watched a videotape of a woman the researchers described as either a librarian or a waitress.
- Woman in the videotape noted that she liked beer and classical music
- When later asked what they remembered about her, participants who believed she was a librarian were more likely to recall that she liked classical music.
- Those who believed she was a waitress were more likely to remember that she liked beer.
- WHY? → their schema of the woman led the participants to look for, and therefore tend to find and encode into long-term memory, characteristics she displayed that fit their schema of her.
- Participants exhibited such schema-consistent memory even when interviewed a week later.
What is the application of the misinformation effect/
- The use of eyewitness testimony is often the most influential piece of trial evidence.
- Recollection of events can be influenced by how questioning is conducted.
- False confession can be coerced and fully believed by the ‘confessor’
What is the availability heuristic and ease of retrieval?
- The availability heuristic: Judging the frequency of an event based on the ease with which it is brought to mind.
- Schema based
- Tversky & Kahneman (1973)
- QUESTION: Are there more words that start with R or words with R as the 3rd letter
- RESULTS: Start with R = more; R is 3rd letter = less
- Wrong though, far more (there’s 2 right there!) words with R as 3rd letter
- Application: Med Students/Clinical Psych classes
- people in psych classes see psychological symptoms everwhere after that learn about it → over-apply it
- The ease of retrieval effect: judge how frequently an event occurs on the basis of how easily they can retrieve a certain number of instances of that event.
- Schwarz et al. 1991
- Come up with 6 vs. 12 examples when they behaved assertively (vs. unassertively).
- DV: How assertive or unassertive they thought they were.
- If asked to come up with 12, they believe they have less of the trait then if asked to come up with 6, why?
- Because it is harder to come up with 12 examples, so the difficulty of having to come
up with 12 makes people think they must not have as much assertiveness, whereas
its easy to come up with 6, so the ease with which they generate 6 examples makes them think they must be very assertive.

How do we perceive people?
- Topper Chewsy → had bad blood from game before
- came behind him, punched in the jaw from behind, passed out fell →he fell on top of him → ended up breaking the guy he punched’s neck .
- Was he a thug or caught up in an ugly part of the game?
- Slater → steward on Jet Blue
- Was a steward for 2 decades at this point
- Taxiing, person grabs bag from
overhead - Argues with Slater, bag falls out of overhead hit Slater in head
- Gets on intercom
- ’20 years’ ‘that’s it, I’m done’
- ‘Go f— yourselves’
- Grabs two beers and slides down the emergency slide
- Drives home
- Weird guy or just pushed too far
and finally had it?
What are Attribution Theories?
- Attribution theories describe how people explain the causes of their own and others’ behaviour.
- We make causal attributions about many aspects of our own lives and others’.
- Often automatic, rapid (recall experiential system) →
- Often make intuitive attributions about behaviour
What is the Heider and Simmel Experiment and what did it test?
- CAUSAL ATTRIBUTIONS
In one study (Heider and Simmel, 1944), people watched a rather primitive animated film in which a disk, a small triangle, and a larger triangle moved in and out of a larger square with an opening.- The participants were then asked to describe what they saw (see figure 4.2).
- People tended to depict the actions of the geometric objects in terms of causes, effects, and intentions, such as “The Larger triangle chased the smaller triangle out of the room [the larger square].”
- This tendency, along with his observations of how people talked about their social lives in ordinary conversation, led Heider to propose that people organize their perceptions of action in the social world in terms of causes and effects.
- Heider referred to such explanations as causal attributions - explanations of an individual’s behaviour.
- They’re important; eg. when an employee is late, whether the employer attributes that behaviour to the person’s laziness or her tough circumstances can determine whether she is fired or not.
What are the Automatic Processes in Causal Attribution.
-
Causal schema come from two primary sources (Kelley, 1973)
- Personal experiences
- General cultural knowledge
-
When events don’t readily fit a causal schemas
- Rely on what is salient or highly accessible
- “Top of the head phenomenon”
- Often, this is the person/individual.
What is Dimensions of Attributions/Locus of Causality (Heider, 1958)?
There are 4 dimensions to attributions:
- Internal attribution (disposition) – a person’s behavior was caused by something internal, such as his/her attitudes, character, or personality
- External attribution (situation) – a person’s behaviour was caused by something external, such as the situation; assume that most other people in that same situation would behave similarly.
STABILITY OF CAUSE
- Stable – a person’s behaviour is reliably caused by the same thing
- Unstable– a person’s behaviour is not reliably caused by the same
thing
- These dimensions can combine in different ways
An Example of Attributions Theory?
- Go to the bar and go out with Fred
- Fred gets into a fight → not fun
- Fred is always getting into fights
- Internal stable
- Avoid Fred
- > ALTERNATIVELY
- Fred was in a bad mood
- Just got divorced
- Internal/External, unstable attribution
- Give Fred the benefit of the doubt
Why do we make internal vs. external attributions: Fundamental Attribution Error (FAE)?
- aka correspondence bias
- We overestimate the extent to which other’s behaviour is due to internal, dispositional factors and we underestimate the role of situational factors
- Behaviour, we often believe, corresponds to disposition.
- People’s tendency to draw correspondent inferences, attributing behaviour to internal qualities of the actor and, consequently, underestimating the causal role of situational factors,
What was Jones and Harris’ Study (1967) on and what did it show?
- ON FUNDAMENTAL ATTRIBUTION ERROR
- Participants watch a debater whose arguments are either pro-Castro or anti-Castro. They are told that the debater was either given a choice on which side to debate or he had
no choice. (2 independent
variables) - What is the debater’s real attitude?
How Pro-Castro is the debater?
(dependent variable) - FOUND that in the chosen condition, ppl seemed to make a reasonable assessment: if they chose pro-castro, they rated them as more pro-castro; if they chose anti-castro they rated them as anti-castro
- But these conditions were actually assigned
- However, the other half of participants were told that the writer didn’t have a choice in whether to advocate for or against Castro; instead the experimenter had assigned what side the writer should take.
- Logic would suggest that the lack of choice would make the position advocated by the essay a poor basis fro guessing the author’s true attitude.
- However, these participants, despite knowing the essay writer had no choice, also rated his attitudes as corresponding to the position he took in the essay.
What is the Three Stage Model of Attribution (Gilbert et al., 1988 based on dual process models)?
- First you notice the behaviour (see sb do sth)
- They then make an automatic dispositional inference
- then, if you have the capacity, you override or add situational correction to that fundamental attribution error.(3. If observers have sufficient accuracy motivation and cognitive resources available, they modify their attributions to take into account salient situational factors.)
- This model predicts that ppl will be especially likely to ignore situational factors and to make the FAE when they have limited attention and energy to devote to attributional processing.
