Regional brain activity, measured by H215O PET, was investigated during recognition memory and word-stem cued recall of words in order to compare the neural correlates of two components of memory retrieval-effort and success-as a function of task. For each task there was a baseline and two retrieval conditions. In one retrieval condition (zero density), none of the test items corresponded to wo...

1. introduction language teachers frequently observe a gap between their students' potential competence and their performance in the class. anderson (1993) attributes this to the fact that human has a limited processing capacity and is not able to attend to various aspects of a task simultaneously. this limitation causes l2 learners not to be able to focus on both meaning and form at the same t...

We compared the effects of guessing vs. choosing an upcoming task. In a task-switching paradigm with four tasks, two groups of participants were asked to either guess or choose which task will be presented next under otherwise identical conditions. The upcoming task corresponded to participants' guesses or choices in 75 % of the trials. However, only participants in the Choosing condition were ...

The present study was designedto test the efficacy of using Electroencephalogram (EEG) and Event-Related Potentials (ERPs) for making task allocation decisions. Thirty-six participants were randomly assigned to an experimental, yoked, or control group condition. Under the experimental condition, a compensatory tracking task was switched between manual and automatic task modes based upon the par...

Background: Patients with depression demonstrate cognitive impairment on a wide range of cognitive tasks, particularly putative tasks of frontal lobe function. We wanted to investigate the possibility that patients are impaired at cognitive ‘branching’, a process requiring holding in mind one goal while performing sub-goal processes. This task has been previously demonstrated to activate anteri...

We present a new sufficient condition for the schedulability of preemptable, periodic, hard-real-time task sets using the very simple static-priority weight-monotonic scheduling scheme. Like a previous condition due to Baruah et al., our condition actually determines pfair schedulability. Pfairness requires that the schedule, in addition to being periodic, schedules each task at an approximatel...

هدف اصلی این تحقیق بررسی تاثیر برنامه ریزی زمانی، هم چنین افزایش میزان پیچیدگی تکالیف در نظر گرفته شده بصورت همزمان، بر دقت و صحت و پیچیدگی عملکرد نوشتاری زبان آموزان می باشد. بدین منظور، 50 نفر از دانش آموزان دختر در رده ی سنی 16 الی 18 سال به عنوان شرکت کنندگان در این زمینه ی تحقیق در نظر گرفته شدند و به دو گروه آزمایشی و کنترل بصورت اتفاقی تقسیم شدند. اعضای گروه آزمایشی هر دو تکلیف ساده و پی...

A test of whether patients suffering from a severe closed-head injury (CHI) were affected by disproportionate dual-task costs compared to those of healthy control participants was carried out through a direct comparison of CHI effects on dual-task (psychological refractory period, or PRP) performance and on single-task performance. In the dual-task condition of the present experiment, independe...

Background: Words in the Mental Lexicon (ML) construct semantic field through associative and/ or semantic connections, with a pervasive native speaker preference for the former. Non-native preferences, however, demand further inquiry. Previous studies have revealed inconsistent Lexical Access (LA) patterns due to the limitations in the methodology and response categorization. Objectives: To f...

This study was an assessment of how children's achievement attributions were influenced by their age, attentional focus, gender, and success or failure experience. Older and younger elementary school children performed a memory task under either self-focusing or task-focusing instructions. After performance, half of the children in each condition were given success feedback and the other half f...
