Abstract
The phenomenon where small numbers produce faster left than right responses and large numbers produce faster right than left responses (The SNARC effect) has been used as evidence for obligatory activations of magnitude. In two experiments, I used the SNARC effect to examine crosstalk using a psychological refractory period (PRP) paradigm. In Experiment 1, subjects made a parity judgment to the second number, while ignoring the first number in session 1 or performing a magnitude judgment on the number in session 2. In Experiment 2, subjects performed a magnitude judgment on the second number. They ignored the first number in session 1 or performed a parity judgment on the number in session 2. The results supported two conclusions. First, presentation of a number produced obligatory representations of magnitude even if the number was to be ignored. Second, early representations of magnitude resulted in crosstalk on processing of the subsequent number.
