Criterial Noise Effects On Rule-Based Category Learning: The Impact Of Delayed Feedback, Shawn W. Ell, David A. Ing, Todd W. Maddox

Variability in the representation of the decision criterion is assumed in many category learning models yet few studies have directly examined its impact. On each trial, criterial noise should result in drift in the criterion and will negatively impact categorization accuracy, particularly in rule-based categorization tasks where learning depends upon the maintenance and manipulation of decision criteria. The results of three experiments test this hypothesis and examine the impact of working memory on slowing the drift rate. Experiment 1 examined the effect of drift by inserting a 5 s delay between the categorization response and the delivery of corrective feedback, …

Neuroscientific research methods, such as brain imaging techniques, have increasingly been applied to social cognitive research efforts and, in particular, to the study of the self. In this essay we discuss the ability of such research to shed light on the emergent, dynamic psychological phenomenon of self. Although neuroscientific tools can be useful for gaining general knowledge about associated underlying structures, a careful consideration of the methodological and theoretical issues discussed herein is necessary to avoid simplifying or reifying the self.
