چکیده

9 10 Abstract We created a novel eye movement version of the 11 n-back task to measure spatial working memory (WM). 12 Rather than one continuous trial, discrete trials were 13 presented in order to develop a simpler WM task. In 14 Experiment 1, we varied the visibility of the final stimulus 15 to maximize the difference in performance between 0-back 16 and 1-back tasks (WM effect). In Experiment 2, we 17 administered the optimized task to children. In Experiment 18 3, we further simplified the task. Both adults and children 19 easily completed our task, displaying significant WM effects. 20 Further, similar WM effects were obtained in our original and 21 simplified n-back spatial WM tasks, demonstrating flexibility. 22 Because WM deficits are often an early feature of disease and 23 a marker of disease progression, our saccadic measure of 24 spatial WM may be particularly useful in hard-to-test 25 populations, such as patients and children, and may have 26 application in brain-imaging studies that require discrete trials.

The Effect of Working Memory Training on Vocabulary Recall and Retention of Iranian EFL Learners: The Case of Dual N-Back Task

This study examined the effect of working memory training on vocabulary recall and retention ofIranian EFL learners using dual N-back task technique. To this end, 50 EFL learners at IslamicAzad University of Shoushtar were randomly assigned to the experimental (n = 25) and control (n= 25) groups. Before the treatment, a vocabulary test was administered to the participants to assessthe participa...

Using Eye Movement Analysis to Study Auditory Effects on Visual Memory Recall

Recent studies in affective computing are focused on sensing human cognitive context using biosignals. In this study, electrooculography (EOG) was utilized to investigate memory recall accessibility via eye movement patterns. 12 subjects were participated in our experiment wherein pictures from four categories were presented. Each category contained nine pictures of which three were presented t...

Interference with spatial working memory: an eye movement is more than a shift of attention.

In the present experiments, we examined whether shifts of attention selectively interfere with the maintenance of both verbal and spatial information in working memory and whether the interference produced by eye movements is due to the attention shifts that accompany them. In Experiment 1, subjects performed either a spatial or a verbal working memory task, along with a secondary task requirin...
