Table 1. Mean reaction times (in ms) and percentage of errors (in italics) for the “different” trials obtained in the Experiment.

		Contiguous			Non contiguous 1-apart			Non contiguous 2-apart

Note: Mean reaction times and percentage of errors for the “same” trials were 590 ms (7.29%), 596 ms (11.41%) and 601 ms (10.85%) for the digit, letter and symbol strings, respectively; Transposition cost is the outcome of the subtraction of the values in the Transposition condition from those in the Replacement condition.
