The present study investigated the effects of task type (cognitive vs. sensory) and source complexity (number of displays to be monitored) of the performance, workload, and stress associated with vigilance. Results affirmed the utility of the cognitive-sensory task distinction of the vigilance taxonomy, although in contrast to previous research the cognitive task was associated with lower perfo...

with regard to the impossibility of preparing learners for each situation that they might encounter in their life, it is more logical to teach them how to cope with unexpected challenges. helping learners ‘learn how to help themselves’ can be facilitated by means of tasks and activities in the classroom context. this paper presents some of the find- ings of a study on iranian young learners bet...

Task variation is an integrative method aiming at the importance of learner-to-learner interactions in a wide range of learning contexts and fostering authentic use of language and meaningful communication. This study investigated the impact of task variation on the accuracy and complexity of Iranian EFL learners’ oral speech. In so doing, 80 intermediate EFL learners, majoring English at the I...

Introduction: To study sentence comprehension in Persian-speaking Patients with Aphasia considering the factors of complexity. Methods: In this cross-sectional study, the performance of 6 non-fluent aphasic patients were tested and their performance was compared to 15 matched control group. Comprehension of semantically reversible sentences was assessed using a binary sentence-picture matching...

Task  repetition  is  now  considered  as  an  important  task-based  implementation  variable  which can affect complexity, accuracy, and fluency of L2 speech. However, in order to move towards theorizing  the  role  of  task  repetition  in  second  language  acquisition,  it  is  necessary  that individual variables be taken into account. The present study aimed to investigate the way task r...

Complexity of simultaneous interpreting has long attracted the interest of researchers and led them to explore different linguistic, psychological, cognitive, social, and neurological factors involved in enabling the human mind to perform such a difficult task. Within the framework of cognitive studies of interpreting, the authors of this study aimed at exploring the relationship between select...

Article history: Received 1 August 2009 Accepted 15 September 2009 Financial and accounting tasks require high levels of concentration as well as cognitive capacity. Today, advanced technology can help facilitate the effective and efficient completion of such tasks. At the same time, however, these same technologies can interrupt work flow and create work-related stress, thus having a deleterio...

the aim of this study was to compare the effects of cognitive-attentional and cognitive-motor load on the performance of bimanual coordination skill. 31 female students (mean age 25+2 years) from shahid beheshti university attending were selected voluntarily and divided randomly into three groups: single group (n=11), cognitive group (n=10) and cognitive-motor group (n=10). single group partici...

Dual-task activities are essential within everyday life, requiring visual–spatial memory (VSM) and mobility skills. Navigational is an important component of VSM needed to carry out activities, but this often not included in traditional tests such as the Corsi block tapping test (CBT). The Walking Test (WalCT) allows both navigational be tested together, well allowing measures gait collected, t...
