Learning across experiences: an ERP study of memory integration.

Abstract (Swedish)
This study investigated how individuals combine information learned across
temporally separate events in order to make novel inferences through memory integration, utilising EEG to provide a novel investigation with high temporal resolution. Participants completed an associative inference task (Zeithamova & Preston, 2010) modified for EEG across three experiments, during which they learned stimulus pairs that shared a common item (AB/CB) along with control stimulus pairs (XY) in two encoding windows before being
tested for their memory of these premise associations and, crucially, their ability to infer relationships between stimuli whose previous associated pairs shared a stimulus, but had not been viewed together (AC inference).... (More)

Experiments 2 and 3 included novel auditory context manipulations to investigate the influence that novelty and familiarity has on the memory
integration process when the context is or is not task-relevant. Despite previous memory integration research highlighting the significance if the neural activity differences in the time window where participants encode overlapping stimuli pairs (e.g. Backus et al., 2016; Zeithamova, Dominick & Preston, 2012), the current research found limited evidence of memory integration processes in the second encoding window. During the context
manipulation experiments, no evidence of the encoding-retrieval (E-R) overlap effect was found for the context congruent ERPs. Implications of the findings and avenues for future research are discussed. (Less)
