Attentional cueing effects are reversed during locomotion

Abstract

Everyday human cognition and behaviour evolved in dynamic and ever-changing environments, but static paradigms still dominate experimental research despite concerns about generalisability of the results. In the case of attention, traditional stationary studies show that pre-orienting attention with spatial cues leads to faster, more accurate responses. However, how movement and environmental features shape such attentional processes in everyday behaviour remains unknown. Here we show that active movement through curved corridors reverses the typical spatial attention effect, with faster response times and higher accuracy for stimuli incongruent to implicit spatial cues provided by the movement direction, contradicting previous findings from static settings. We found that early (N1) and late (P3) attention-related electrophysiological responses were modulated by environmental features and motor demands. The posterior N1-component, reflecting visuo-spatial attention, showed decreasing amplitudes as turning angles and motor-control demands increased for congruent stimuli appearing on the side of the turning direction. Similarly, the P3-complex varied with motor and visual processing demands for congruent stimuli, showing decreased amplitudes as motor-control demands increased. We propose that congruent stimuli, displayed against a dynamically changing visual context, increase pulvino-cortical processing load and slowing early visual processing that affect behavioural responses. Incongruent stimuli, however, are displayed against a predictable context allowing faster target processing. These findings challenge attentional mechanisms assumed consistency across static and dynamic settings, revealing instead their dependence on behavioural and environmental context. We advocate for naturalistic paradigms, arguing that moving beyond static experiments could reshape core views on cognition and behaviour.
