Abstract:
This thesis examines the intricacies of false memory and whether emotional valence may play a part in the susceptibility of memory errors. In order to examine emotional memory performance a new experimental paradigm was developed: the categorised emotional images paradigm. Experiment 1a investigated the robustness of the paradigm and revealed enhanced memory performance especially for positive images and more conservative response biases for emotional (both positive and negative) images in younger adults. Possible confounding factors of arousal (Experiment 1b) and perceptual distinctiveness (Experiment 1c) were ruled out. Experiment 2 revealed that emotional distinctiveness and the subsequent re-experiencing of emotional images can be a facilitative method in protecting memory from errors but that secondary task requirements can hinder the capacity to use such sensitivities. Experiment 3 and 4 explored how remembering and knowing can be used as a method to disentangle and explore how the underlying processes in memory operate. Experiment 3 showed that there is maintenance of the conservative bias and gist recognition in aging but older adults lose the emotional recollective advantage that was present in the younger adults. Experiment 4 used an alternative paradigm using emotional faces to illustrate that the effects of valence are domain specific and indicates that it is exceptionally important for memory researchers to be flexible in how they approach emotion and memory interactions. It is especially important for memory research to be sensitive to the subtleties of the emotional paradigm under investigation.
