It is proposed that knowledge of motor commands is used to distinguish self-generated sensation from externally generated sensation. In this paper, we show that the sense of self-agency, that is the sense that I am the one who is generating an action, largely depends on the degree of discrepancy resulting from comparison between the predicted and…

The increasing use of eye movement paradigms to assess the functional integrity of brain systems involved in sensorimotor and cognitive processing in clinical disorders requires greater attention to effects of pharmacological treatments on these systems. This is needed to better differentiate disease and medication effects in clinical samples, to…

The study concerned the effects of induced interference, employing a backward masking paradigm, on the processing of sensory information and on the formation of perceptual-motor responses in 20 dyslexic and 20 normal children (mean age 8.2 years). (Author/PHR)

Motor skill learning is a dynamic process that continues covertly after training has ended and eventually leads to delayed increments in performance. Current theories suggest that this off-line improvement takes time and appears only after several hours. Here we show an early transient and short-lived boost in performance, emerging as early as…

The Zahlen-Verbindungs-Test (ZVT) represents a highly feasible measure of information-processing speed that correlates quite highly with standard psychometric tests of intelligence. The present study was designed to identify specific stages of the sensorimotor processing system that may account for individual differences in overall variability of…

Introduces consumer affairs specialists to engineering psychology, a relatively new academic field that brings perspectives of psychology to the design of various consumer products. (Author)

Several studies have shown an improvement in the performance of motor skills following imagined performance of the skill, or "mental practice." One unresolved issue has centered on whether the effect being observed is in fact a practice effect. As one alternative, the effect may be a simple instance of planning when to use a skill, or…

Comments on G. Zivin's model of expressive behavior development, presenting support for (1) affect-induced and (2) spontaneously generated emotion and expressive behavior. Argues that these phenomena are mediated by sensorimotor and sensory-perceptual processes. (HOD)

The purpose of this study was to determine the influence that varying types of labels have on the organization of a series of movements in memory. Subjects were presented with a series of movements on a positioning task. They were provided with numeric labels for each movement held in the series. Results indicated that labels play an important…

Recent models of beginning reading processes are described, and the author offers the following summarization: (1) Models at present focus on cognitive aspects of reading; little attempt has been made to incorporate affective aspects into the models. (2) Several different theoretical positions within psychology representing a wide variety of…

Two experiments were conducted to determine the effect of aging on encoding and response selection stages of a choice reaction time task. Results suggested reducing stimulus discriminability may affect information processing prior to the encoding stage, but the encoding stage is the primary locus of the slowing which accompanied aging.

This book presents a holistic approach to multicultural educational issues by viewing them in terms of the student as a physical, psychosocial, cognitive, ethical, and spiritual being. Conversely, these levels of a student's being cannot be seen apart from the student's cultural identities. This unique book demonstrates that, in a pluralistic…

It has been hypothesized that the use of techniques to enhance motor skill acquisition and retention in the elderly may retard the onset of retirement, result in the continuation of a productive professional career, allow continued participation in recreational activities, and possibly slow the decline in physiological functions that normally…
