Neurophysiology of implicit timing in serial choice reaction-time performance.
Neural representations of time for the judgment of temporal durations are reflected in electroencephalographic (EEG) slow brain potentials, as established in time production and perception tasks. Here, we investigated whether anticipatory processes in reaction-time procedures are governed by similar mechanisms of interval timing. We used a choice reaction task with two different, temporally reg...
متن کاملthe effects of time planning and task complexity on accuracy of narrative task performance
هدف اصلی این تحقیق بررسی تاثیر برنامه ریزی زمانی، هم چنین افزایش میزان پیچیدگی تکالیف در نظر گرفته شده بصورت همزمان، بر دقت و صحت و پیچیدگی عملکرد نوشتاری زبان آموزان می باشد. بدین منظور، 50 نفر از دانش آموزان دختر در رده ی سنی 16 الی 18 سال به عنوان شرکت کنندگان در این زمینه ی تحقیق در نظر گرفته شدند و به دو گروه آزمایشی و کنترل بصورت اتفاقی تقسیم شدند. اعضای گروه آزمایشی هر دو تکلیف ساده و پی...
Dopaminergic effects on simple and choice reaction time performance in Parkinson's disease.
The present study examined whether premovement central neural processing in Parkinson's disease was related to functional motor disability and plasma L-dopa concentration. Reaction time (RT) performance in simple and choice RT tasks was assessed while plasma L-dopa levels were controlled by continuous IV L-dopa infusion in five parkinsonian patients. Five age-matched controls performed the same...
متن کاملRelative performance of the two hands in simple and choice reaction time tasks
There is evidence that the left hemisphere is more competent for motor control than the right hemisphere. This study investigated whether this hemispheric asymmetry is expressed in the latency/duration of sequential responses performed by the left and/or right hands. Thirty-two right-handed young adults (16 males, 16 females; 18-25 years old) were tested in a simple or choice reaction time task...
متن کاملSome experiments on simple and choice reaction time.
4 experiments in simple and choice reaction time (RT) are reported. Experiment I examines the effect of monetary payoffs on the accuracy and variability of time estimation. Experiment II examines the effect of moving the position of a narrow payoff band along the time axis on the variability of observed RTs. This appears to alter the proportion of bona fide reactions (of low variability) and of...
