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...

CTC is a toy cipher designed by Courtois in order to prove the strength of algebraic attacks. In this paper we study the differential and the linear behavior of the 85 S-boxes version, which is attacked using algebraic techniques faster than exhaustive key search. We show that an n-round variant of the cipher can be attacked by a linear attack using only 2 known plaintexts, with a negligible ti...

Recently, an innovate switch architecture named Contention-Tolerant Crossbar switch, CTC(N), was proposed. Without resolving output contentions, the controllers are able to fully distributed in CTC(N). It largely reduces the scheduling complexity. However, It has been proved that the saturated switch throughput is bounded by 63% without any scheduling algorithms. In this paper, we present an i...

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...

Game manuals and tutorial scenarios are insufficient for new players to learn games of deep complexity such as highly realistic tactical simulations of modern battlefields. Adding post-game after-action reviews improves the situation, but these typically do not provide guidance during the mission and tend to focus on quantitative feedback, rather than specifics about what the player did wrong a...

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...

Abstract Educational researchers have been confronted with a multitude of definitions task complexity and lack consensus on how to measure it. Using cognitive load theory-based perspective, we argue that the learners experience is based element interactivity. Element interactivity can be determined by simultaneously considering structure information being processed knowledge held in long-term m...
