Forgetting Flashcards

Q

Ebbinghaus

A

Created the forgetting curve

Learned loads of non-sense syllables and tested himself with relative relearning time trials (savings)

Until immidiate recall = 100%, curve
- 20 min = 58%
- 1 hr = 44%
- 9 hrs = 36%
- 1 day 33%

E. Did find time of the day effect (13% better in the morning), Heller did not. Were however very similar curves.

Q

A

Effect of position of syllable had large effect;

recency effect (and little priming effect)

Q

Function of forgetting

A

Q(t) = (1+u1t) -a (savings as a function of time)

Power function so gives straight line when plotted in log-log

Q

Permastore

A

The platau of forgetting, Bahrick showed forgetting continues until about 3 to 12 years (depending on material), than halts. He called remaining memories permastore

Q

Proactive interference

A

Recall becomes worse with three word Brown-Peterson paradigm.

The previous trials start interfering with the new ones, so recall worsens

Same with ‘head start’. Cueing someone with some words of a list messes up the retrieval process and worsens performance.

Q

Release of interference

A

Unexpected stimuli. Eg if the three words were within one category and you suddenly change to another, the interference is released

Q

Fan effect

A

The more you know, the more you forget.

Associative interference. = when there are more related items linked to a single cue, it takes longer to retrieve any one of them.

Q

Interference theory

A

Idea that memory gets worse if two memories interfere. Seen in
- Part-set cueing (helping with a set)
- Fan effect
- Proactive interference
