The Role of Contextual Schema Consistency in Cross-episodic Memory Integration: An EEG Analysis
(2019) PSYP01 20191Department of Psychology
- Abstract
- One of the essential human functions that enables us to make inferences about relationships between persons, events, or objects; to solve problems; to be creative; and crucially, to learn effectively is the phenomenon episodic memory integration. This study investigated effects of cross-episodic context shifts during encoding of picture-word pairs in an associative memory paradigm that tested indirect association (inference) as well as direct association (single association) learning within a sample of 29 Swedish-speakers. Context shifts during encoding were manipulated by showing either the same, schema-congruent, or schema-incongruent real-life videos. In contrast to previous research, context stimuli were only present during study... (More)

This study investigated effects of cross-episodic context shifts during encoding of picture-word pairs in an associative memory paradigm that tested indirect association (inference) as well as direct association (single association) learning within a sample of 29 Swedish-speakers. Context shifts during encoding were manipulated by showing either the same, schema-congruent, or schema-incongruent real-life videos. In contrast to previous research, context stimuli were only present during study phases of the material and were not displayed or cued at test phases. Furthermore advancing previous designs that used solely behavioral measures, continuous temporally high-resolution electroencephalography (EEG) was recorded and analyzed to investigate spatiotemporal dynamics of memory integration. The present results suggested that participants reliably learned indirect associations. Contrary to the hypotheses, no context-specific differences in inference performance were found as well as no context-specific differences in event-related potentials during study phases. However, in line with the predictions, EEG analyses revealed differences in mean amplitudes between encoding and baseline trials at various topographic regions, supporting the account of integrative encoding underlying memory integration as opposed to logical inference. Both scientific and societal implications are discussed alongside critically reflecting on limitations of the present study. (Less)
