- Abstract
- Behavioural studies have suggested that number manipulation involves shifting attention along a left-to-right oriented continuum. We measured horizontal gaze patterns in two eye-tracker experiments that combined the free exploration of visual scenes with a verbal numerical task. The first experiment required participants to compare numbers (from 20 to 70) to a reference (45). A rightward shift was observed when the number was larger than the reference, starting after hearing the number decade and lasting until response production. The second experiment investigated the mental solving of addition (43+4) and subtraction problems (53-6). A first difference was observed just after hearing the operator: the plus sign shifted the eye rightward compared to the minus sign. A second difference between addition and subtraction was observed later, after problem offset, but only in problems requiring carrying or borrowing procedures. These findings evidence the effect of computational constraints on the time course of attention shifts.
