Flashcards in Episodic memory Deck (52)
Name a theory of encoding.
Levels of Processing theory (Craik & Lockhart, 1972)
Recall is a copy of an event. True/false?
False - recall is a record of how you process an event.
Which levels can info be processed at?
Shallow - perceptual features
Deep - semantic features
What type of processing leads to better recall?
Craik & Tulving (1975) had pps read unrelated words and use different types of processing at study (encoding). What were these types of processing & what did they involve?
Shallow - upper/lower case judgement
Intermediate - rhyme judgement
Deep - sensible-or-not judgment
What did Craik & Tulving (1975) find when pps were given a surprise recognition test?
Pps who used deep processing at encoding had better recognition than those who used shallow/intermediate
Which researcher/s claimed that deep processing might not always be sufficient for episodic remembering?
Craik & Kester (1999) found that WHAT at encoding could impair memory performance?
What underlies the LoP effect?
What is elaboration?
Relating a to-be-remembered item to other info known about the item (other stored knowledge)
What does the elaboration hypothesis state?
We are more likely to remember something if we can relate it to other things we know about
What influences retention?
The amount of info we have about an item (number of things it is linked to in memory)
What type of processing did Craik & Tulving (1975) produces more elaboration?
Semantic processing produces more elaboration than non-semantic processing --> the item is more likely to be remembered
Memory for words that appeared in sentences judged to be sensible (______) was better than memory for words judged to be nonsensical (______)
Memory for words that appeared in sentences judged to be sensible (CONGRUENT) was better than memory for words judged to be nonsensical (INCONGRUENT)
What is the congruency effect?
Congruent info provides more elaboration because it ties items more closely to stored knowledge
We have more elaboration if we process the correct semantic info about the item during encoding --> remember the item better
Does memory depend more on elaboration or the distinctiveness of the encoded info?
Memory depends on distinctiveness of the encoded info (how well it stands out from other items in memory; a more distinctive memory trace) rather than elaboration
What type of processing does Hunt & Elliot (1980) say will produce more distinctive encoding?
Recall of a distinctive sentence was better than recall of an elaborative sentence. Who found this?
Bransford et al. (1979)
Which are words more likely to be distinct in terms of - their meaning (semantic) or physical appearance (non-semantic)?
Words are more likely to be distinct in terms of meaning
Distinctiveness theory states that semantic encoding will always be better than non-semantic encoding. True/false?
False - semantic encoding isn't always better than non-semantic encoding
Which researcher/s found evidence for the idea that semantic encoding is not always better than non-semantic?
Eyesenck (1979) - used a non-semantic task with unusual word pronunciations
Found that pps' memory after the task was as good as that after a semantic task
However, he did conclude that semantic processing is USUALLY more likely to lead to distinctive processing
Winograd (1981) compared distinctiveness & elaboration by having pps look at faces.
1. Scanned each face (encoded features --> elaboration) + rated the most distinctive feature (distinctiveness)
2. Rated the most distinctive feature (distinctiveness)
Pps then identified which faces they had seen before.
What did they find?
There was no difference in memory performance between the two groups.
- distinctiveness is key (E+D was no better than just D)
- having elaboration may increase the likelihood of detecting a distinctive feature
What are some criticisms of the Levels of Processing theory?
X no objective way to measure depth
X assumes that processing levels are linear & go from one stage to the next (appearance>sound>meaning); research suggests different types of processing occur in parallel (overlap)
X don't know whether we can fully suppress semantic processing (must be overlap)
X benefit of semantic processing depends of the nature of the test
What is 'organisation'?
Relationships between items on a list, actions in an event, etc.
What type of material is better remembered - organised or unorganised?
Organised material is better remembered
Pps were shown 20 words in 5 categories - presented randomly (unorganised) OR the categories were grouped together (organised)
Recall was highest for the organised group
Who did this study?
What is the generation effect?
Info that you generate yourself is better remembered than info that is presented to you
How did Glisky & Rabinowitz (1985) study the generation effect?
Pps generated single words from word fragments then tried to recognise the words in a test
Pps read words or generated their own words at BOTH encoding & retrieval
Found that words generated at encoding (study) were better recognised than words read at encoding (= standard generation effect)
Words generated at encoding AND test were better recognised than words generated at encoding & read at test
What is the effect of transfer-appropriate processing
Recognition is best if the same fragments are generated at both study & test
