The Relationship Between Mindfulness, Cognitive Intrusions, and Recollection: An ERP study

The purpose of the present study was to investigate whether mindfulness and cognitive intrusions predict recollection. Using electroencephalogram methodology, we investigated 31 participants who performed a recognition task and reported situational mindfulness as well as task-irrelevant (TII) and task-relevant intrusions (TRI). We used behavioral measures (response accuracy) to analyze performance effectiveness and event-related potentials (ERP) to measure processing efficiency (compensatory processes) associated with performance of the task. Results suggest that being mindful during a task slightly improves recognition of old and new but not similar probes. Although worrying about the outcomes (i.e., TRI) facilitates improvement in true recognition of old probes, it also impairs correct rejection of new probes. Moreover, TRI predicted the strength of ERP effects associated with compensatory processes involved in recollection. We conclude that mindfulness slightly improves recognition without involvement of the compensatory effort and worrying partly increases responding accuracy at the cost of diminished processing efficiency.
