The optimal neural strategy for a stable motor task requires a compromise between level of muscle cocontraction and synaptic gain of afferent feedback.
Increasing joint stiffness by cocontraction of antagonist muscles and compensatory reflexes are neural strategies to minimize the impact of unexpected perturbations on movement. Combining these strategies, however, may compromise steadiness, as elements of the afferent input to motor pools innervating antagonist muscles are inherently negatively correlated. Consequently, a high afferent gain an...

20 Increasing joint stiffness by co-contraction of antagonist muscles or compensatory reflexes are neural 21 strategies to minimize the impact of unexpected perturbations on movement. Combining these strategies, 22 however, may compromise steadiness as elements of the afferent input to motor pools innervating antagonist 23 muscles are inherently negatively correlated. Consequently, a high affer...

Effects of cognitive functions on feedback request strategy and learning of a perceptual motor task
Taking individuals' cognitive abilities into consideration can play an important role in the initial stages of learning motor skills. So, the purpose of the present study was to investigate the effect of cognitive functions on feedback request strategy and learning of a perceptual motor task. A number of 60 university male students with a mean age of 22/4 years (SD = 1/99) were selected through...

تمایل به ارزیابی جایگزین و تعویض آن با آزمون سنتی مداد و کاغذ در سالهای اخیر افزایش یافته است. اکثر زبان آموزان در کلاس های زبان از نمره نهایی که استاد تعیین میکند ناراضی اند. این تحقیق جهت بررسی ارزیابی در کلاس های زبان انگلیسی به هدف رضایتمندی زبان آموزان از نمره هایشان انجام گرفته است که در آن نمرات ارائه شده توسط سه گروه ارزیاب (ارزیابی خود دانشجو، همسالان واستاد) در مهارت های تولید (تکل...
