objectives: the visual-motor skill is one of the major factors in the learning process. visual-spatial and visual analysis skills are components of the visual motor skill. any deficiency in visual-motor skills and their components often causes problem in writing and learning processes in children. the aim of this study was to investigate the effect of occupational therapy (o.t.) intervention on...

introduction: aluminum is known as a neurotoxic element which causes neurodegeneration, learning deduction and movement disorders. aluminum ions in the brain cause serious problems such as alzheimer, parkinson and other degenerative diseases. on the other hand, zinc is a dietary element essential for several biological processes, modulates neurotransmission in brain regions and associates with ...

Objective(s):Neurotoxicity of anticancer drugs complicates treatment of cancer patients. Vinblastine (VBL) is reported to induce motor and cognitive impairments in patients receiving chronic low-dose regimen. Materials and Methods: The effects of VBL treatment on motor, learning and memory functions of male and female Wistar rats were studied by behavioral related tests. Animals were given chro...

Introduction: The interaction between steroid hormones and neurotransmitters such as GABA has been proved. The regulation of muscimol binding to high-affinity GABAA receptors by estradiol and progesterone has been studied within distinct brain regions using in vitro quantitative autoradiography. There are few studies about the mechanism of the effect of steroid hormones on behaviors such as ...

This study examined motivational effects of feedback on motor learning. Specifically, we investigated the influence of social-comparative feedback on the learning of a balance task (stabilometer). In addition to veridical feedback (error scores reflecting deviation from the target horizontal platform position) about their own performance after each trial, two groups received false normative inf...

OBJECTIVE This study investigated the effects of qualitative and quantitative knowledge of results (KR) on the acquisition of a motor skill. It was hypothesized that there would be differences in performance during skill acquisition and retention, depending on the type of feedback given. Qualitative KR was in the form of verbal encouragement and quantitative KR was in the form of an algebraic n...

Learning from past mistakes is of prominent importance for successful future behavior. In the present study, we tested whether reinforcement learning signals in the brain are predictive of adequate learning of a sequence of motor actions. We recorded event-related potentials (ERPs) while subjects engaged in a sequence learning task. The results showed that brain responses to feedback (the feedb...
