Nonstrategic Contributions to Putatively Strategic Effects in Selective Attention Tasks
Risko, Evan F.; Blais, Chris; Stolz, Jennifer A.; Besner, Derek
Journal of Experimental Psychology: Human Perception and Performance, v34 n4 p1044-1052 Aug 2008
Proportion compatible manipulations are often used to index strategic processes in selective attention tasks. Here, a subtle confound in proportion compatible manipulations is considered. Specifically, as the proportion of compatible trials increases, the ratio of complete repetitions and complete alternations to partial repetitions increases on compatible trials but decreases on incompatible trials. This confound is demonstrated to lead to an overestimation in the magnitude of the proportion compatible effect in the context of both a Stroop and a Simon task. Implications for previous research and directions for future research using proportion compatible manipulations are discussed. (Contains 4 figures, 3 tables, and 3 footnotes.)
