Spatial components in the mental representations of numeric and symbolic magnitudes: Extending the SNARC effect


With English-language readers as participants, in an experiment requiring pair-wise comparative judgments of numerical magnitude, typical SNARC effects were obtained. With comparisons of the remembered size of animals, SNARC depended on the direction of the instruction. In both cases the continua are organized from left to right corresponding to the direction of reading. On the other hand, with Hebrew- and Arabic-language readers, exactly the same configuration of findings was obtained except that the spatial direction in each domain was reversed; the mental continua are organized from right to left corresponding again to the direction of reading.
