Response control or inhibition is one of the cornerstones of modern cognitive psychology, featuring prominently in theories of executive functioning and impulsive behavior. However, repeated failures to observe correlations between commonly applied tasks have led some theorists to question whether common response conflict processes even exist. A…

Reaction time (RT) and event-related potential (ERP) measures were used to examine the relationships between psychopathic symptoms and three major attention networks (alerting, orienting, and executive attention) among a community sample of youth. Antisocial Process Screening Device (APSD; Frick and Hare 2001) total and subscale scores were…

The goal of the current study was to determine the extent to which the perceived self-regulation deficits across behavioral, cognitive, and emotional domains seen in children with ADHD explain the association between the severity of ADHD symptoms and parenting stress. Participants for this study included 80 children (mean age = 10 years, 9 months)…

The authors propose a simple behavioral economic model (BEM) describing how reinforcement and interval timing interact. The model assumes a Weber-law-compliant logarithmic representation of time. Associated with each represented time value are the payoffs that have been obtained for each possible response. At a given real time, the response with…

Background: The present study examined the distinct properties of executive functioning in relation to ADHD symptoms, as well as functional outcomes associated with ADHD. In line with the dual-pathway model of ADHD, executive functioning and delay aversion were expected to show independent effects on ADHD symptoms. Furthermore, relations to early…

A long-standing issue in the study of how people acquire visual information centers around the scheduling and deployment of attentional resources: Is the process serial, or is it parallel? A substantial empirical effort has been dedicated to resolving this issue. However, the results remain largely inconclusive because the methodologies that have…

A model of John Dewey's theory of reflective thought, as revised in 1933, is reviewed and its implications for the creative process explored. Reflective thought differs from random thought in its "chaining" feature, which entails a consecutive ordering so that each idea determines its successor while referring to its predecessor. (VW)

The concept of error detection plays a central role in theories of executive control. In this article, the authors present a mechanism that can rapidly detect errors in speeded response time tasks. This error monitor assigns values to the output of cognitive processes involved in stimulus categorization and response generation and detects errors…

Attempts to model the human production of language under time constraints based on an analysis of hesitation and spontaneous self-repair in a corpus of spoken human dialogs. The model used divides language production into conceptualization of the message to be conveyed, formulation of words and grammatical structure for the message, and…

Investigates the relationships between levels of cognitive complexity and three levels (graphic, formal, and inferred) of modeling complexity in community college students. (GA)

Background: Whether selective attention is a primary deficit in childhood Attention Deficit Hyperactivity Disorder (ADHD) remains in active debate. Methods: We used the "perceptual load" paradigm to examine both early and late selective attention in children with the Primarily Inattentive (ADHD-I) and Combined subtypes (ADHD-C) of ADHD. Results:…

The literature on human aggression is large and diverse. Some of it is theory-driven, but much of it dwells on solving social problems rather than on building general models and research paradigms. This paper examines some of the research programs and theoretical emphases in aggression research and presents theory convergences to see how these…

Delay of Gratification (DG) and Delay Discounting (DD) represent two indices of impulsive behavior often treated as though they represent equivalent or the same underlying processes. However, there are key differences between DG and DD procedures, and between certain research findings with each procedure, that suggest they are not equivalent. In…

Cognitive style refers to preferences for, or dominant modes of, information processing. Cognitive styles tend to be bipolar and less value-laden than ability or aptitude measures. Conceptualizations of cognitive style differ in the number of styles and the degree of metacognitive control over them which individuals are presumed to have. The Hill…

Describes an instructional experiment aimed at helping sixth-graders sustain reflective thought processes in composition independently. Instruction included modeling of thinking aloud, clue use stimulating self-questioning, and direct strategy instruction emphasizing dialectical synthesis of conflicting ideas. Results indicate gains were made at…
