this study explored the effect of contrastive phrase resynthesis instruction ongaining the teachability hypothesis stages in self-paced versus time-constrained oralproduction and recognition. three groups (i.e., 23 learners) of high beginner femalelearners in an english language institute were randomly selected from a cohort oflearners. one group received contrastive metalinguistic instruction ...

Multi-task learning is a paradigm, where multiple tasks are jointly learnt. Previous multi-task learning models usually treat all tasks and instances per task equally during learning. Inspired by the fact that humans often learn from easy concepts to hard ones in the cognitive process, in this paper, we propose a novel multi-task learning framework that attempts to learn the tasks by simultaneo...

a r t i c l e i n f o Working memory span tasks are popular measures, in part, because performance on these tasks predicts performance on other measures of cognitive ability. The traditional method of span-task administration is the experimenter-paced version, whose reliability and validity have been repeatedly demonstrated. However, computer-paced span tasks are becoming increasingly more popu...

BACKGROUND Recent evidence suggests that impaired central sensorimotor integration may contribute to deficits in movement control experienced by people with chronic ankle instability (CAI). This study compared the effects of dual-task and walking speed on gait variability in individuals with and without CAI. METHODS Sixteen subjects with CAI and 16 age- and gender-matched, able-bodied control...

Self-paced versions of many paradigms could have utility in probing cognitive systems. To validate several self-paced n-back paradigms, fourteen subjects performed four variations of the working memory task using visually presented letters as stimuli. Several areas in the frontal lobe, the anterior cingulate and a parietal network were consistently activated in the four variations: identity of ...

Neuroimaging activation studies typically observe signals during two or more periods of differing cognitive activity which are then analyzed by a subtraction to test for localized neuroanatomical dissociations between cognitive tasks. Significant activity found between task conditions is frequently assumed to reflect a novel cognitive process present in one task and not the other. We present a ...
