Table 2. Mean response time (ms) and error rate summary data for trials omitting and including response repetitions.

	Omitting Response Repetitions		Including Response Repetitions
	Mean	SD	Mean	SD
cC RT	667	50	662	49
iC RT	678	54	673	58
iI RT	705	52	693	54
cI RT	699	52	701	51
cC error rates	22%	12%	22%	9%
iC error rates	22%	10%	24%	10%
iI error rates	35%	16%	38%	13%
cI error rates	36%	13%	41%	13%

Note. RT = response time; cC = congruent trial preceded by a congruent trial; iC = congruent trial preceded by an incongruent trial; iI = an incongruent trial preceded by an incongruent trial; cI = incongruent trial preceded by a congruent trial.
