Why do movements drift in the dark? Passive versus active mechanisms of error accumulation.
When vision of the hand is unavailable, movements drift systematically away from their targets. It is unclear, however, why this drift occurs. We investigated whether drift is an active process, in which people deliberately modify their movements based on biased position estimates, causing the real hand to move away from the real target location, or a passive process, in which execution error a...

متن کاملthe effect of explicit versus implicit error correction on writing of iranian intermediate efl learners
در این پایان نامه دو روش اصلاح اشتباهات نوشتاری زبان آموزان بزرگسال ایرانی در سطح متوسط مورد بررسی قرار می گیرد. در روش اول (explicit) اشتباهات بطور مستقیم و در روش دوم (implicit) اشتباهات بصورت غیر مستقیم اصلاح می شود. برای انجام این تحقیق از دو گروه 15 نفری استفاده شده است. به زبان آموزان در هر جلسه یک موضوع انشا داده شده است. این کار در 15 هفته (15 جلسه) تکرار شده است. مقایسه نتایج این آزمون...
Brain representation of active and passive movements.
During active and passive (driven by a torque motor) flexion and extension of the right elbow, regional cerebral blood flow (rCBF) was measured in six healthy, male volunteers using positron emission tomography and the standard H2(15)O injection technique. During active as well as during passive movements of the right elbow there were strong increases in rCBF, identical in location, amount, and...
متن کاملSignal processing in the vestibular system during active versus passive head movements.
In everyday life, vestibular receptors are activated by both self-generated and externally applied head movements. Traditionally, it has been assumed that the vestibular system reliably encodes head-in-space motion throughout our daily activities and that subsequent processing by upstream cerebellar and cortical pathways is required to transform this information into the reference frames requir...
