Task complexity is critical in cognitive efficiency and fluid intelligence. To examine functional limits in task complexity, we examine the phenomenon of goal neglect, where participants with low fluid intelligence fail to follow task rules that they otherwise understand. Though neglect is known to increase with task complexity, here we show that - in contrast to previous accounts - the critica...

Today, learners’ interaction and collaborative task performance have attracted increasing attention from language teachers and researchers. The present study investigated whether collaborative pre-planning, task complexity manipulation, and language proficiency level play a role in learners’ interactions. To this end, 128 EFL learners from two different language proficiency levels carried out t...

http://dx.doi.org/10.1016/j.anbehav.2014.03.019 0003-3472/ 2014 The Association for the Study of A The ‘cognitive capacity hypothesis’ states that song complexity could potentially be used by prospective mates to assess an individual’s overall cognitive ability. Several recent studies have provided support for the cognitive capacity hypothesis, demonstrating that individuals with more complex s...

The purpose for the present study was to examine how person and task characteristics affected the performance, workload, and stress of vigilance. Task type (sensory versus cognitive) and source complexity (1, 2, or 4 displays to be monitored) were the dimensions of vigilance examined, and several person characteristics selected based on an energetic-resource approach to vigilance. Relationships...

The current study used the Space Fortress game (Donchin, 1989) to study the effects of training and instruction in acquisition of complex skills. The game requires flexible coordination of perceptual, cognitive and motor components in a dynamically changing environment. We examined whether effective instruction can be developed for such a task in the same way that instruction is developed for a...

This study examined the effects of aural and written prompts under two planning conditions (i.e. pre-task planning and no planning) on complexity, accuracy, and fluency of test takers' writing production. Forty learners in an English institute, who had already been classified as intermediate according to the Oxford Placement Test, were assigned to two planning conditions (i.e. no planning and p...

clinical trial committee (ctc) has been established in food and drug organization (fdo), in 2003 to assure efficacy and safety of all types of medicinal products which are meant to be registered in iran drug list and/or obtain market authorization.all clinical trial files, meeting minutes and databases in ctc secretariat in fdo were reviewed. relevant information and data extracted, analyzed an...

This study investigated the effect of sequencing tasks from simple to complex along +/- reasoning demands on fluency in writing task performance of English as Foreign Language (EFL) learners. The participants of this study included 90 intermediate EFL learners from three intact class divisions at the Islamic Azad Uni- versity, Shahr-e-Qods Branch. They were distributed in three groups: Experime...

This study compared the effects of teacher-provided direct and indirect written corrective feedback and manipulation of resource-directing dimensions of task cognitive complexity along +/- Here and Now condition on the grammatical accuracy of Iranian intermediate EFL learners’ narrative writing tasks. There were 45 participants in the study who were randomly assigned to three experimental group...

This paper analyses the effects of manipulating the cognitive complexity of L2 oral tasks on language production. It specifically focuses on self-repairs, which are taken as a measure of accuracy since they denote both attention to form and an attempt at being accurate. By means of a repeated measures design, 42 lower-intermediate students were asked to perform three different tasks types (a na...
