Verbal-spatial and visuospatial coding of number-space interactions

A tight Correspondence has been postulated between the representation; of number and space The spatial numerical association of response codes (SNARC) effect. which reflects the observation that people. respond faster with the left-hand side to small numbers and with the right-hand side to large numbers. Is regarded as strong evidence for this correspondence The. dominant explanation of the SNARC effect a that it results from visuospatial coding of magnitude (e.g. the mental number line hypothesis) In a series of experiments, we demonstrated that this is only part of the story and that verbal-spatial coding influences processes and representations that have been believed to be. purely visuospatial Additionally, when both accounts were directly contrasted, verbal-spatial coding was observed in absence of visuospatial coding Relations to other number-space interactions and implications for other tasks are discusse
