Punishment-related memory-guided attention: Neural dynamics of perceptual modulation

摘要: Remembering the outcomes of past experiences allows us to generate future expectations and shape selection in long-term. A growing number studies has shown that learned positive reward values impact spatial memory-based attentional biases on perception. However, whether memory-driven extend punishment-related received comparatively less attention. Here, we manipulated recent contextual memories became associated with successful avoidance punishment (potential monetary loss). Behavioral electrophysiological measures were collected from 27 participants during a subsequent attention task, which tested for effect associations. Punishment significantly amplified effects visual search processes within natural scenes. Compared non-associated scenes, paired lead faster responses targets presented at remembered locations. Event-related potentials elicited by target stimuli revealed acquired motivational value specific locations, virtue their association punishment, dynamically affected neural signatures early processing (indexed larger P1 earlier N1 potentials) (as indicated reduced N2pc potentials). The present results our understanding how memory, attention, mechanisms interact optimize perceptual decision real world environments.
