ab: Summary: It has been argued that numbers are spatially organized along a
“mental number line" that facilitates left-hand responses to small
numbers, and right-hand responses to large numbers. We hypothesized
that whenever the representations of visual and numerical space are
concurrently activated, interactions can occur between them, before
response selection. A spatial prime is processed faster than a
numerical target, and consistent with our hypothesis, we found that
such a spatial prime affects non-spatial, verbal responses more when
the prime follows a numerical target (backward priming) then when it
precedes it (forward priming). This finding emerged both in a
number-comparison and a parity judgment task, and cannot be ascribed to
a “spatial-numerical association of response codes" (SNARC). Contrary
to some earlier claims, we therefore conclude that
visuospatial-numerical interactions do occur, even before response
selection.
