Based on Robinson’s Cognition Hypothesis, this study explored the effects of task complexity on the lexical complexity of Iranian EFL students’ argumentative writing.This study was designed to explore the manipulation of cognitive task complexity along +/-single task dimension (a resource dispersing dimension in Robinson’s triadic framework) on Iranian EFL learners’ production in term of lexica...

In the present study, two different models of task complexity; namely, limited attentional capacity model and cognition hypothesis were examined. To this end, the manipulation of cognitive task complexity along +/- single task dimension on Iranian EFL learners’ production in terms of fluency was explored. Based on the results of the writing test of TOFEL (2004), 48 learners were selected as the...

objectives: the present study aimsed to examine the reliability of forceplate parameters under both single and dual task conditions and in different levels of postural difficulty. methods & materials: the healthy elderly+65, were assessed with aone-week interval, with a random combination of three levels of postural difficulty (i.e., standing on a rigid surface with eyes open, standing on a rig...

1. Preliminaries In this section we list a few results from the literature that will be utilized in the proof of Theorem 1. Proposition 1 (Lemma 1 in (Ben-David et al., 2010)). Let d be the VC dimension of the hypothesis set H and S1, S2 be two i.i.d. samples of size n from D1 and D2 respectively. Then for any δ > 0 with probability at least 1− δ: disc(D1, D2)≤disc(S1, S2)+2 √ 2d log(2n) + log(...

the aim of this study was to compare the effects of three types of balancetraining: single task, dual task under fixed priority instructional set (fp) and dualtask under a variable priority instructional set (vp) on the balance of the elderly.the participants were 36 elderly over 65 years old from kerman province whowere randomly divided into three groups (each 12 subjects) based on burg pretes...

this study examined the effects of task complexity on written narrative production under different task complexity conditions by efl learners at different proficiency levels. task complexity was manipulated along robinson’s (2001b) proposed task complexity dimension of here-and-now (simple) vs. there-and-then (complex) in. accordingly, three specific measures of the written narratives were targ...

We combined behavioral and electrophysiological measures to find out whether redundancy gain effects in pop-out visual search are exclusively determined by bottom-up salience or are modulated by top-down task search goals. Search arrays contained feature singletons that could be defined in a single dimension (color or shape) or redundantly in both dimensions. In the baseline condition, both col...
