Memory Integration - fundamental feature at a cost? An EEG study.
(2022) PSYP01 20221Department of Psychology
- Abstract
- This study investigated whether integrative encoding in an associative inference paradigm (AIP) using naturalisitc narrative videos to present the stimuli, comes at cost of memory specificity by testing source- and details-memory of the presented videos and measuring electroencephalography (EEG). Based on earlier work (e.g. Carpenter et al., 2017), it was expected that integrative encoding in the form of memory generalization measured via an associative inference test would be related to lower memory specificity. Furthermore it was hypothesized that potential effects found in the neural data during encoding would be related to memory specificity. The behavioral data of N = 37 participants were analyzed using ANOVAs and the neural data by... (More)

Furthermore it was hypothesized that potential effects found in the neural data during encoding would be related to memory specificity. The behavioral data of N = 37 participants were analyzed using ANOVAs and the neural data by computing event-related-potentials (ERPs) and time-frequency representations (TFRs). It was revealed that there was no cost in terms of lower memory specificity due to integrative encoding. Trials related to associative inference revealed no significant difference from control trials. Trials related to unsuccessful associative inference resulted in higher memory specificity than the control. During the encoding phase, integrative encoding was demonstrated by significant effects in the TFRs, but this could not be related to the behavioral data. These results suggest the involvement of integrative encoding and parallel separate storage of item-related memories and thus flexible retrieval (Less)
