The Effect of Emotional Valence on Memory Quality and Confidence Judgements
(2003)Department of Psychology
- Abstract
- In the present study, our aim was to investigate how emotional valence influences the recollective experience and confidence judgements of memory. We also investigated if subliminal manipulation can have a valence dependent effect on the realism in confidence judgements. In Experiment 1, the first phase involved participants being shown pictures and asked to select the pictures that had either negative or positive valence. In the test phase, participants decided first if the picture was "old" or "new", after which they made confidence judgements of their responses. Pictures reported as "old" was finally appraised on the quality of the memory trace; if subjects "remembered", "knew" or "guessed" that they had previously seen the picture.... (More)

Pictures reported as "old" was finally appraised on the quality of the memory trace; if subjects "remembered", "knew" or "guessed" that they had previously seen the picture. Experiment 2 was conducted in the same fashion, with the exception of a subliminal presentation preceding each picture in the test phase, which was expected to cause an increase in "know" responses. The results were partly in line with previous research. Significant results were obtained for the confidence variable, showing that subjects were more confident in their responses with negative images. Albeit not significant, the results showed that recollective experience was somewhat higher for negative valence than for positive. It is also discernable that subliminal manipulation of fluency lead to an increase in familiarity, although it did not influence realism in confidence judgements. (Less)
