EXTRA EFFORT DURING MEMORY RETRIEVAL MAY BE ASSOCIATED WITH
INCREASES IN EYEWITNESS CONFIDENCE
- witnesses aware of importance of their testimony but also testify for more
selfish reasons
- testify as a form of self-presentation strategy where witnesses may seek to
impress others in the courtroom with their skill and acumen
- witnesses may work hard to testify accurately so that they look good to
themselves
- pressure on the witness while on the stand to ‘do well’
- according to self-perception theory, testifying witnesses may arrive at
confidence judgments by observing their own behaviour thus, witnesses
will give higher confidence ratings on the witness stand
- hypothesis: it is the amount of effort that mediates the level of witness
confidence, it should not matter whether the motivation for trying hard is
selfless or selfish in either case the additional effort should produce higher
confidence ratings
- confidence ratings were positively related to reported effort and negatively
correlated with perceived difficulty
- confidence ratings and accuracy estimate were highly correlated for both the
low-motivation and the high-motivation conditions
EYEWITNESS MEMORY OF A SUPERMARKET ROBBERY: A CASE STUDY OF
ACCURACY AND CONFIDENCE AFTER 3 MONTHS
- 14 witnesses of an armed robbery were interviewed after 3 months
- security camera recordings were used t assess memory accuracy
- of all info remembered, 84% was correct
- confidence is not a reliable predictor of accuracy
- central witnesses (those interviewed by the police) recalled significantly
more units of information than the peripheral witnesses (who were less
involved and were not questioned by the police)
- accuracy of correct information recalled was the same as for the peripheral
witnesses
- most answers are given with the maximum level of confidence
- 78% of units of information given were correct, and of that information, 84%
was correct
