How attention controls naming: Lessons from Wundt 2.0.

Abstract

When models of the attentional control of vocal naming, applied to color-word Stroop and picture-word interference, were first computationally implemented and examined in 1990, an implementable model proposed by Wundt (1880, 1902) was not considered. Although these modern computer models, and more recent ones, clarify many aspects of the interference, most models fail to explain its time course, as outlined in Roelofs (2003). Wundt s (1902) model assigns a key role to top-down inhibition, which is absent in most of the modern models. Here, an implementation of his model is presented, called Wundt 2.0. The necessity of perceptual inhibition was demonstrated by computer simulations of the interference and its time course, and supported by existing evidence from oscillatory brain activity in the alpha frequency band. Moreover, a new empirical study showed that Raven scores measuring the general intelligence factor g, discovered by Wundt s student Spearman (1904), predict the magnitude of the Stroop effect in fast errors, in line with the model and evidence on alpha band activity. Also, the study provided evidence that response inhibition is absent during vocal naming in the Stroop task. To conclude, Wundt s model has stood the test of time and provides a number of enduring lessons for our understanding of attention and performance.
