Visual Spatial Sketchpad:
language expands what we can do with _________
phonological loop.
_________ keeps track of what you’re doing, keep track of what you’re up to. It directs traffic, causes you to do particular actions. (blocks everything but what you’re currently think of. It is the voice in your head. (it’s perfectly okay to hear voices in your head as long as you understand it is you talking to yourself))
central executive

Episodic Buffer
By your late ____ you brain is visibly slowing.
There is no question working memory slows as we age.

We can determine what part of the brain handles paying attention to what we’re doing by looking for brain activity while having people do tasks that require that ability.
_____ _____ appears to involve the dorsolateral prefrontal cortex
Dynamic updating
FYI : Maintaining attention on things we’re are already monitoring appears to involve the ventral lateral prefrontal cortex
FYI
Older folks show less/more (pick one) dorsolateral prefrontal lobe activity

____________________
- Context Restatement- The witness is asked to describe the scene and surroundings, in hope this will cue more memory from context (what they wore, what they were doing, what the weather was, what the surroundings were).
- Report Everything- anything might be a cue to an important memory
- Recall from a changed perspective- a different view may cue different memories
- Recall in reverse order
Many police officers have adopted the first two parts, but not the last two, because they feel it doesn’t add much and takes too much time

The Cognitive Interview
Children under 6 find the ______ confusing.
It doesn’t work as well when long retention intervals are involved (more than a few days)
The Cognitive Interview
____________
“A sample will only resemble, or be representative of a, population if the former is sufficiently large.”
The bigger the sample, the closer our estimated frequency resembles the actual frequency
The Law of Large Numbers
______- if we sample more and more things we are more likely to get an average.
Belief that a particular proportion will be evident after taking sufficiently large sample
The smaller the number in the sample relative to the total group, the more samples vary from the ______
The Law of Average

percentages
Events are ______ of each occurrence has no influence on the probability of the next one.
The probability of independent events occurring together (conjunction) is the product of the probability of each event. (fancy way of saying must multiply them together).
The probability of one independent event occurring or the other one (disjunction) is the sum of each probability.
independent
_________ The belief that a small sample can represent a large group (if you had a defective Toyota, that means they can be trusted)
The Representativeness Heuristic
_________ The belief that past independent events influence current ones (I’ve lost continuously, so I’m due to wim)
Ex: I’m loosing too many times. I’m bound to win. (it’s not logical thinking)
The Gambler’s Fallacy
_________ The belief that the odds of two things happening together can be greater than the odds of the individual events (Kahneman’s study where people think the odds a person is a WOW player and a fan of LOTR is greater than they’re merely one of them)
The Conjunction Fallacy

Randomness
_______: we tend to judge how likely an event is by whether we can readily retrieve examples of it
