Note. Standard deviations are given in parentheses; PG = positive suggestion group; NG = negative suggestion group; RT (reaction times) are in milliseconds; CR (correct responses) are in percentages; SFE = Stroop Facilitation effect; SIE = Stroop Interference effect; SE = global Stroop effect; * indicates a significant difference (p < .05) between suggestion and baseline conditions. For correct responses, a negative value indicates a standard compatibility effect (facilitation or interference).
