Pillsbury (1908) suggested that deciding to search for something in a scene consists of nothing more than forming a visual image of the target. If so, imaging should trigger search even when it would be more advantageous not to search. Subjects were cued to form an image of a specified object (e.g., tiger) and to press a key when they had done so. This initiated the presentation of a sequence o...

An unresolved issue in the task-switching literature is whether preparatory reconfiguration occurs before a change of task. In this study, we used event-related potentials (ERPs) to determine whether preparatory reconfiguration occurs during two different task-switching procedures: voluntary and cued task switching. We focused on two ERP components that index different cognitive operations. The...

The purpose of this research was to analyze EFL writing tasks in two of the most popular English for Speakers of Other Languages (ESOL) exam preparation courses in Iran, namely IELTS and TOEFL. Having collected the criteria of writing task appropriateness in light of the process-oriented approach to writing instruction, we asked 60 learner participants to rate EFL writing tasks in 3 IELTS and 3...

The ability to resist distracting stimuli whilst voluntarily focusing on a task is fundamental our everyday cognitive functioning. Here, we investigated how this develops, and thereafter declines, across the lifespan using single task/experiment. Young children (5–7 years), older (10–11 young adults (20–27 (62–86 years) were presented with complex visual scenes. Endogenous (voluntary) attention...

The functional role of the mediodorsal thalamic nucleus (MD) and its cortical network in memory processes is discussed controversially. While Aggleton and Brown (1999) suggested a role for recognition and not recall, Van der Werf et al. (2003) suggested that this nucleus is functionally related to executive function and strategic retrieval, based on its connections to the prefrontal cortices (P...

Despite recent advances in clarifying the neural networks underlying rehabilitation in Parkinson's disease (PD), the impact of prolonged motor learning interventions on brain connectivity in people with PD is currently unknown. Therefore, the objective of this study was to compare cortical network changes after 6 weeks of visually cued handwriting training (= experimental) with a placebo interv...

The current study examines the impact of different task types on learning prepositions in form and meaning- focused interaction enhancement- based classes. The participants were 57 second Year University students enrolled in three intact lab classes at Tabriz Islamic Azad University.  The first group was provided with form-focused interaction enhancement, the second with the meaning-focused int...
