Abstract This study was intended to compare collaborative and individual task planning effects on Iranian EFL learners’ writing performance. Therefore, a group of 90 upper intermediate EFL learners were placed in three groups of Collaborative Task planning, Individual Task planning, and Control. In the experimental groups, participants were asked to do task planning collaboratively and individu...

The nature of the spatial representations that underlie simple visually guided actions early in life was investigated in toddlers with Williams syndrome (WS), Down syndrome (DS), and healthy chronological age- and mental age-matched controls, through the use of a "double-step" saccade paradigm. The experiment tested the hypothesis that, compared to typically developing infants and toddlers, and...

Two experiments are reported which examine how manipulations of visual attention affect adult speakers’ linguistic choices regarding word order and verb use when describing simple visual scenes.

Gender differences in ability and achievement have been studied for some time and have been conceptualized along verbal, quantitative, and visual-spatial dimensions. Researchers recently have called for a theory-based approach to studying these differences. This study examined 1,100 boys and 1,100 girls who matched the U.S. population using the Planning, Attention, Simultaneous, Successive (PAS...

the aim of this investigation was to compare the level and the pattern of attention demands of a volleyball jumping serve using a probe reaction time (rt) technique. 14 junior elite volleyball players performed 60 jumping serves (js) with their preferred hand. jumping serve was performance as the primary task and verbal rt that was administered in four probe positions (pp) as secondary task. re...
