Memory Flashcards
Abernethy (1940)
arranged for a group of students to be tested weekly prior to a certain course beginning. Some were tested in their classroom by their teacher, some in their classroom by a different teacher, some in a different classroom with their teacher and some in a different classroom with a different teacher. The group tested in their classroom by their teacher did best
Articulatory Process
holds words that are heard or seen and silently loops them like an inner voice; a type of maintenance rehearsal
Baddeley and Hinch (1970)
participants were asked to perform two tasks simultaneously, either two tasks involving the articulatory loop or one task involving the articulatory loop and one taks involving both the central executive and articulatory loop. They found that participants did better in tasks that required separate parts of the brain, which supports the working model of memory
Baddeley and Hitch (1977)
involved asking rugby players to try and remember the names of teams they had played so far in the season, week by week. Most of the players had missed at least some games. The results clearly showed that accurate recall did not depend on how long ago the matches took place, more important was the number of games played in the meantime. However, Baddeley himself stated that the tasks given to participants were too close together and in real life, the events would be more spaced out, which might affect results
Bransford and Johnson Experiment
a number of experiments which illustrated the role of schemata in our understanding and recall of information. I one experiment, participants were read a passage and asked to recall it as accurately as possible. Half were given a title and half were not. The half that were given a title remembered the passage better, as the title provides a schema so information can be appropriately stored and recalled more easily
Bunge et al (2000)
used fMRI scans to see which parts of the brain were most active when participants were doing two tasks. He found that the same brain areas were active in either dual or single task conditions but there was significantly more activation in dual task conditions
Capacity of LTM
potentially infinite
Capacity of STM
five to nine digits, but digits are recalled better than letters, increases with age
Capacity of STM Experiment
by George Miller in 1956, involves an experimenter listing random sequences of numbers, making the sequence longer each time until the participants can no longer accurately recall the sequence
Carter and Cassaday (1998)
looked at the effect of anti-histamines, giving anti-histamines to their participants. They had a mild sedative effect and this created a psychological state different from the normal. The participants had to learn lists of words and then recall them. In conditions where there was a mismatch between internal state at learning and recall, there was more forgetting
Central Executive
this decides how slave systems are allocated. It has limited capacity; data arrives from senses but can’t be held for long
Ceraso (1967)
showed that if participants in the Baddeley and Hitch study were tested 24 hours later, there is significant recovery so interference may be temporary. This research does not investigate whether information has disappeared or can be recovered later
Clifford and Scott (1978)
found that people who saw aviolent film attack remembered fewer items of information than a control group whosaw a less stressful version, showing that stress has a negative on recall
Clive Wearing
a man whose hippocampus was destroyed by a virus leaving him unable to form new memories
Close Reading
according to studies on memory, if you want to memorise something, you should only close read after first having skim-read something
Coding of Memory Experiment
done by Alan Baddeley in 1966, involved getting a group of participants to recall various lists of words in the correct order, either immediately or after being given a twenty-minute distraction task, lists of words were acoustically similar, acoustically dissimilar, semantically similar and semantically dissimilar
Coding of LTM
generally semantically
Coding of STM
generally acoustically
Cognitive Interview
developed by Fisher and Geiselman in 1992, involves four components
Reporting Everything
a component of cognitive interview, ask the witness to record every detail of the event, without asking leading questions, allowing the witness to go off on tangents
Mental Reinstatement/Original Context
a component of cognitive interview, mentally recreate the original context or go back to the scene of the crime
Changing the Order
a component of cognitive interview, trying alternative timelines through the incident
Changing the Perspectitve
a component of cognitive interview, imagining how it would appear to other witnesses
Concept Formation
the process of forming concepts, for example, ‘animal’ is a concept that involves sub-concepts such as ‘birds’, ‘fish’ or ‘mammals’, which can then be further divided. It is easier to remember things if you can make links between concepts
Daffenbacher (1983)
reviewed 21 studies and hypothesised that stress and performance follows a u-curve. Witnesses are either too stressed because something excited and dangerous is happening or are under-stressed because they didn’t realise that they witnessed a crime
Decay
forgetting in short-term memory because there isn’t enough time for maintenance rehearsal
Declarative Memory
theorised by Cohen, memories that are consciously recalled, suggesting that episodic and semantic memories are the same
Digit Span
the amount of numbers someone can fit into their short-term memory
Digit Span Test
developed by Jacobs in 1887, this involves a researcher giving a number of a digits and the participant has to recall them all in order. The researcher then increases the amount by one and the participant has to recall again until they cannot recall the correct order
Displacement
forgetting in short-term memory because there is not enough capacity
Duration of LTM
potentially infinite
Duration of LTM Experiment
an experiment by Harry Bahrick in 1975, involved testing people on their high school graduation class by asking them to list their names or match names to faces, proved that long-term memory can last forever, but deteriorates after a certain amount of time, especially after the age of 75
Duration of STM
around 18 seconds
Duration of STM Experiment
done by Peterson and Peterson in 1959, involves giving a person a consonant trigram to remember, then asking them to count back in threes from a three digit number before repeating the trigram. The time elapsed increases by three seconds each time until the participant can no longer remember the trigram
Encoding Specificity Principle
in 1983, Tulving’s research into retrieval failure discovered a consistent pattern to the findings. He summarised this pattern in what he called the ESP. This states that if a cue is to help us to recall information then it has to be present at encoding and retrieval
External Cues
context-dependent cue
Internal Cue
state-dependent
Endel Tulving
in 1885, realised that the multi-store model’s view of long term memory was too simplistic and inflexible, so proposed that there are three types of long-term memory containing different types of information
Enhanced Cognitive Interview
Fisher et al (1987) developed additional elements of the cognitive interview. The enhanced cognitive interview focused on the social dynamics of the interaction, eye contact, minimising distractions, reducing anxiety, open-ended questions and slow speech
