Variations in stimulus-hand proximity have been shown to alter conflict processing. A stimulus-response (S-R) conflict, for example, was increased when response hands were placed close (proximal) compared to far (distal) from the stimulus in both, visuo- as well as auditory-motor Simon tasks. Conversely, a stimulus-stimulus (S-S) conflict in a classical visual Stroop paradigm was reduced in a proximal compared to a distal stimulus-hand condition. This suggests that stimulus-hand proximity might affect S-S and S-R conflict resolution processes differently. At the same time, it needs to be determined, whether a proximal stimulus-hand condition also reduces the Stroop conflict in an auditory domain where the task-irrelevant information requires pure semantic processing without any reading process. The present study investigated the influence of stimulus-hand proximity on S-S and S-R conflict processing in an auditory gender-categorization Stroop (Experiment 1a and 1b) and Simon task (Experiment 2). Applying the same stimulus materials in all experiments, Experiment 1a and 1b consistently demonstrated that the auditory Stroop effect was unaffected by stimulus-hand proximity, which raises the question to which extent stimulus-hand nearness in previous demonstrations of reduced visual Stroop effects impacted semantic or rather reading processes. In Experiment 2 the auditory Simon effect was significantly increased when the hands were placed near the stimuli, suggesting heightened integration of task-irrelevant spatial stimulus features. These findings highlight that response hands near visual and auditory stimuli heighten spatial feature processing rather than semantic processing.
