UNLABELLED We investigated theoretically and empirically a range of training schedules on tasks with three knowledge types: declarative, procedural, and perceptual-motor. We predicted performance for 6435 potential eight-block training schedules with ACT-R's declarative memory equations. Hybrid training schedules (schedules consisting of distributed and massed practice) were predicted to produc...

EDRS Price MP -$0.25 HC-$0.90 *Literature Reviews, *Perceptual Motor Coordination, *Perceptual Motor Learning, *Reading Achievement, Reading Improvement Reviewed were 28 research studies which investigated the effect of perceptual-motor programs on the reading achievement of students with ave:age or higher intellectual ability. Despite possible criticisms of some investigations, all studies rev...

Intensive training or testing reduces performance on perceptual and sensorimotor tasks. Here we show, for the visual texture discrimination task, that such adaptation-related performance decrements are practically eliminated following practice with a small number of trials and sleep. Thus, short training produces consolidation of an effective memory within the visual neural network, resistant t...

In a crowded dynamic world, temporal expectations guide our attention in time. Prior investigations have consistently demonstrated that temporal expectations speed motor behavior. We explore effects of temporal expectation on perceptual speed in three nonspeeded, cued recognition paradigms. Different hazard rate functions for the cue-stimulus foreperiod were used to manipulate temporal expectat...

Common coding theory states that perception and action may reciprocally induce each other. Consequently, motor expertise should map onto perceptual consistency in specific tasks such as predicting the exact timing of a musical entry. To test this hypothesis, ten string musicians (motor experts), ten non-string musicians (visual experts), and ten non-musicians were asked to watch progressively o...

OBJECTIVE To explore the hypothesis that dopaminergic circuits play a part in the premotor components of the unilateral neglect syndrome, the effects of acute dopaminergic stimulation in patients with neglect were studied. METHODS Two tasks were evaluated before and after subcutaneous administration of apomorphine and placebo: a circle crossing test and a test of target exploration (a modifie...

The use of benzodiazepines to overcome the possible debilitating effects of travel on football performance is a recent phenomenon and indicative of current usage of such drugs. Contemporary psychological theory is critical of many of the measures used to monitor such drugs. This study has created a battery of tests which include some measures which are deemed more ecologically valid and, for pu...

OBJECTIVE To determine whether the impairment of perceptual-motor performance often observed during the initial stages of space flight is attributable to the direct effects of microgravity on sensory-motor input-output relationships or to cognitive overload arising from the variety of stressors encountered in this environment. BACKGROUND Experimental evidence is contradictory, and the present...

PURPOSE To verify the efficacy of a perceptual and visual-motor skill intervention program for students with dyslexia. METHODS The participants were 20 students from third to fifth grade of a public elementary school in Marília, São Paulo, aged from 8 years to 11 years and 11 months, distributed into the following groups: Group I (GI; 10 students with developmental dyslexia) and Group II (GII...
