The present study investigated the effects of cognitive complexity of pedagogical tasks on the learners’ uptake of salient features in the input. For the purpose of data collection, three versions of a decision-making task (simple, mid, and complex) were employed. Three intact classes (each 20 language learners) were randomly assigned to three groups.  Each group transacted a version of a decis...

Objectives: The dominant leg has always received special attention in public health practices and even in professional clinical evaluation and interventions. The aim of this research study was to methodically examine the substrate balance character of the non-dominant leg under dual task conditions and visual deprivation to increase the baseline insight for maintaining body balance and for fall...

The efficiency of how people search for an item in visual search has, traditionally, been thought to depend on bottom-up or top-down guidance cues. However, recent research has shown that the rate at which people visually search through a display is also affected by cognitive strategies. In this study, we investigated the role of choice in visual search, by asking whether giving people a choice...

Attention shifting in the working memory system plays an important role in goal-oriented behavior, such as reading, reasoning, and driving, because it involves several cognitive processes. This study identified brain activity leading to individual differences in attention shifting for dual-task performance by using the group comparison approach. A large-scale pilot study was initially conducted...

We investigate the effects of variations in response requirements on BOLD activation in a visual oddball task and consider implications for fMRI task designs. Sixteen healthy subjects completed 3 runs of a visual oddball task: passive, count and respond. Besides expected activation patterns during passive viewing, we identified joint activations, but more importantly crucial differences between...

The electrophysiological bases of conflict control in a number interference task was measured in 21 healthy study participants using event-related brain potentials (ERPs). In the number interference task, participants were instructed to ignore the number words meaning and to report the number of the number words. The number words were 'two', 'three', or 'four'. We focused on the differences bet...

Patients with posttraumatic stress disorder (PTSD) can show declines in working memory. A dual-task design was used to determine whether these impairments are linked to executive control limitations. Participants performed a Sternberg memory task with either one or four letters. In the dual-task condition, the maintenance period was filled with an arrow flanker task. PTSD patients were less acc...

When two adults jointly perform a task, they often show interference effects whereby the other's task interferes with their own performance (Sebanz, Knoblich, & Prinz, 2003). The current study investigated whether these co-representation effects can be observed in young children. This phenomenon can be used as a criterion for adult-like joint action in children, which has been under debate in e...
