Q

What kind of problems did Clive Wearing have?

A

Musician, no past or future / just a moment to moment consciousness; perceives the world normally, he remembers his wife but not that he has seen her so he has some long term memory about who she is, gets very angry

If something can be lost while something else is perceived it suggests those are two different parts of memory

Q

What are Functional fixedness and Duncker’s candle problem? What helps people to solve the Duncker’s candle problem quickly?

A

Functional fixedness: We don’t see what can used to solve the problem because it is currently serving another purpose

Duncker would bring people into the lab and sit them at a table with a cork board in front of them with props in front of them. Problem is to attach the candle to the corkboard in a way that can be safely burned. Key to the problem is the box.

Repeated the candle problem, when you labeled the box and tacks separately they solved the problem more quickly. Broke functional fixedness, and changed how participants reasoned and solved problems

17
Q

What were the findings of research on the question of whether labels help or hurt memory for pictures?

A

Labels can impact how we remember pictures - more consistent with the label (eye glasses vs. dumbbell) and more likely to remember

18
Q

What is linguistic determinism?

A

that the semantic structure of a particular language determines the structure of mental categories among its speakers. Language determines thought.

English - 1 work for snow, Inuit - 7 words for snow

19
Q

What is linguistic relativity?

A

The language that you speak determines how you perceive, think about, and remember the world around you
