coglabs final

Question 1

Serial position

Answer 1

On each trial, a sequence of letters will appear, with each letter presented for one second. After the sequence has been presented, a set of buttons appears, with a letter, including those just shown. Task is to click on the buttons to indicate which letters were in the sequence (in any order)
IV: serial position
DV: proportion correct

Question 2

Serial position characteristics

Answer 2

U shaped function; primacy effect and recency effect

Question 3

Remember/Know

Answer 3

Phase 1: see a word and an instruction, if the instruction says ‘synonym for’ write down a word with the same meaning as the one shown. If the instruction says ‘rhymes with’ write a word that sounds the same as the target word. Each only shown for 5 seconds
Phase 2: shown a series of words, half of them were shown in phase 1 and half are new words. Task is to answer the question: was this word in phase 1? And if it was, decide whether you remember the word or simply know it was on the list
IV: condition (rhyme, synonym, lure)
DV: proportion of judgments

Question 4

Remember vs Know

Answer 4

Remember: consciously aware of learning (episodic)
Know: recognize (semantic)

Question 5

Statistical learning

Answer 5

Phase 1: see a long, continuous stream of shapes. When the phase is over, we will see some new instructions
Phase 2: determine which sequence is more familiar
IV: comparison ( always, impossible, possible)
DV: proportion correct

Question 6

Encoding specificity

Answer 6

Phase 1: see a pair of words, one in lowercase (the cue) and one in uppercase (target). Read the words silently to yourself
Phase 2: see a pair of words, one in lowercase (the cue_ and one in uppercase (target). Task is to judge if the target (word in uppercase) was shown in phase 1. It doesn’t matter if the cue is the same or different from phase 1, the judgment is always weather the uppercase word was in phase 1
IV: study cue (strong, weak, lure)
DV: proportion correct

Question 7

encoding specificity result

Answer 7

regardless of the strength of association, recall is better when the cue at encoding is the same as the cue at retrieval

Question 8

risky decisions

Answer 8

Wheel of fortune ⇒ wheel has two parts (green = win and red = lose). On some trials, the green area will be larger than red, which indicates that you are more likely to win than lose. On others, the green area will be smaller than the red, which indicates you are more likely to lose than win. If the pointer lands in the green section, you win, if it lands in the red, you lose
Each trial we have to decide between two options: one is guaranteed and the other depends on the spin of the wheel (gamble or take the sure thing)
IV: condition (less vs more risky)
DV: proportion of gamble trials

Question 9

risky decisions conclusions

Answer 9

• more likely to gamble when gamble is less risky
• when the gamble is more risky, we are more likely to gamble when the outcome is framed in terms of losses
• when trying to avoid a large loss, we are more likely to make a risky decision
