Novel n - back spatial working memory task using eye 5 movement response

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 Experime...

Novel n-back spatial working memory task using eye movement response.

We created a novel eye movement version of the n-back task to measure spatial working memory (WM). Rather than one continuous trial, discrete trials were presented in order to develop a simpler WM task. In Experiment 1, we varied the visibility of the final stimulus to maximize the difference in performance between 0-back and 1-back tasks (WM effect). In Experiment 2, we administered the optimi...

Eye movement suppression interferes with construction of object-centered spatial reference frames in working memory.

The brain's frontal eye fields (FEF), responsible for eye movement control, are known to be involved in spatial working memory (WM). In a previous fMRI experiment (Wallentin, Roepstorff & Burgess, Neuropsychologia, 2008) it was found that FEF activation was primarily related to the formation of an object-centered, rather than egocentric, spatial reference frame. In this behavioral experiment we...

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...
