Nonconscious Control Mimics a Purposeful Strategy: Strength of Stroop-Like Interference Is Automatically Modulated by Proportion of Compatible Trials
Klapp, Stuart T.
Journal of Experimental Psychology: Human Perception and Performance, v33 n6 p1366-1376 Dec 2007
The magnitude of the Stroop effect is known to be modulated by the proportion of trials on which the irrelevant word and relevant ink color correspond. This has often been attributed to a conscious strategy of increased (or decreased) reliance on the irrelevant words when these are more likely (or less likely) to correspond to the ink colors. However, the present data from a Stroop-like task involving successively presented arrows indicate instead that this type of modulation can be automatic because it can occur even if the irrelevant stimuli are not phenomenally visible. In this case participants cannot determine the proportion of compatible trials to direct their strategy. An automatic, item-specific associative interpretation can account for these findings.
