Data from three experiments investigating reciprocal SNARC effects with vocal responses
This data set contains the raw data files from three experiments reported in: Richter, M. & Wühr, P. (2024). The reciprocity of spatial-numerical associations of vocal response codes depends on stimulus mode. Memory & Cognition (volume and pages yet unknown). Here is the abstract of the paper: Individuals make faster left responses to small/er numbers and faster right responses to large/r numbers than vice versa. This “spatial-numerical association of response codes” (SNARC) effect represents evidence for an overlap between the cognitive representations of number and space. Theories of the SNARC effect differ in whether they predict bidirectional S-R associations between number and space or not. We investigated the reciprocity of S-R priming effects between number and location in three experiments with vocal responses. In Experiments 1 and 2, participants completed a number-location task with digits as stimuli and location words as responses, and a location-number task with physical locations as stimuli and number words as responses. In addition, we varied the S-R mapping in each task. Results revealed a strong SNARC effect in the number-location task, but no reciprocal SNARC effect in the location-number task. In Experiment 3, we replaced physical location stimuli by location words and digit stimuli by number words. Results revealed a regular and a reciprocal SNARC effect of similar size. Reciprocal SNARC effects thus seem to emerge with verbal location stimuli and vocal responses, but not with physical location stimuli and vocal responses. The S-R associations underlying the SNARC effect for vocal responses thus appear bidirectional and symmetrical for some combinations of stimulus and response sets, but not for others. This has implications for theoretical accounts of the SNARC effect which need to explain how stimulus mode affects the emergence of reciprocal but not regular SNARC effects.
