About this Research Topic
The Stroop task is a well-known psychological experiment named after John Ridley Stroop in 1935. The task consists of challenging selective attention mechanisms in individuals by presenting them a relevant color dimension that must be identified and an irrelevant word dimension that must be ignored. This task is widely used as an investigative tool in the cognitive and clinical science domains both for research purposes and theory development.
Almost thirty years after C. M. MacLeod’s seminal paper, published in 1991, this Research Topic addresses the outstanding question of the locus of the Stroop effect. It concerns evidence for different forms of conflict (response, semantic, and task) and facilitation (response and semantic) thought to comprise the Stroop effect.
The research presented in this Research Topic will evaluate one of the following areas: 1) the methods used to index the different types of conflict; 2) the modulating effects of response mode; 3) potential Stroop effects on response execution; 4) the application of distributional analysis forms (e.g. the ex-Gaussian function), and; 5) evidence for the control over the various forms of conflict.
All studies will provide appropriate consideration to issues such as response contingency, orthogonality of comparisons, and statistical power.
