Dataset for Study "Physical stimulus size primes spatially compatible hand and foot responses"

The mapping was either compatible (small-left, large-right) or incompatible (small-right, large-left). Keys were pressed with the left or right hand in one condition, and with the left or right foot in another condition. In addition, we assessed lateralization of hands, foot, ears and eyes with a questionnaire.

Results showed SSARC effects with both response modalities, but the SSARC effect in foot responses was smaller than that in hand responses. Moreover, hand dominance correlated significantly with the size of the SSARC effects in hand responses, but not with the SSARC effect in foot responses. While the pattern of results is incompatible with polarity-correspondence and working-memory accounts of the SSARC effect, the results are compatible with a specific version of the correlations-in-experience (CORE) principle.

The complete data set consists of 56 text files. Each text file contains the raw data from one participant. Each text file contains 13 columns and 400 rows.

Each column represents a variable. Each row contains the data observed in a particular experimental trial. A detailed description of this dataset can be found in the codebook that has been stored together with the dataset.
