Effects of Hand Proximity and Movement Direction in Spatial and Temporal Gap Discrimination

摘要: Previous research on the interplay between static manual postures and visual attention revealed enhanced selection near hands (near-hand effect). During active movements there is also superior performance when moving towards compared to away from stimulus (direction The “modulated pathways” hypothesis argues that differential involvement of magno- parvocellular processing streams causes near-hand effect. key finding supporting this an increase in temporal a reduction spatial space (Gozli, West, & Pratt, 2012). Since has, so far, only been tested with hand postures, we provide conceptual replication Gozli et al.’s result hands, thus probing generality direction Participants performed or gap discriminations while their right was below display. In contrast al. (2012), discrimination at intermediate not proximity. discrimination, effect without proximity suggests pragmatic attentional maps overshadowed temporal/spatial biases for far/near-hand space.
