How are arbitrary sequences of verbal information retained and manipulated in working memory? Increasing evidence suggests that serial order WM is spatially coded spatial attention involved access retrieval. Based on the idea brain areas controlling also oculomotor control, we used eye tracking to reveal how structure accessed memory. In two experiments, participants memorized a sequence auditory words correct order. While their movements were being measured, they named items self-determined...

Abstract Theoretical models explaining serial order processing link information to specified position markers. However, the precise characteristics of marking have remained largely elusive. Recent studies shown that space is involved in items verbal working memory (WM). Furthermore, it has been suggested, but not proven, accessing these involves horizontal shifts spatial attention. We used continuous electroencephalography recordings show search WM attention processes share same...

Abstract Although humans can hold multiple items in mind simultaneously, the contents of working memory (WM) be selectively prioritized to guide future behavior. We explored whether “same-object” benefits visual processing may also observed WM. fMRI data were collected while participants performed a multistep serial retrocuing task which they first viewed two 2-D objects (coherently moving colored dots). During retention, an initial relevance cue then indicated only or second object...

Abstract Coding serial order of information is a fundamental ability our cognitive system, and still, little known about its neural substrate. This study examined the substrates involved in retrieval that serially stored verbal working memory task using sensitive multivariate analysis approach. We compared activity for memorized items stemming from beginning versus end list assessing degree pattern discordance between positions (beginning vs. end). The present results confirmed refined role...

The human eye scans visual information through scan paths, series of fixations.Analogous to these paths during the process actual "seeing," we investigated whether similar are also observed while subjects "rehearsing" stimuli in visuospatial working memory.Participants performed a continuous recall task which they rehearsed precise location and color three serially presented discs retention interval, later reproduced either or single probed item.In two experiments, varied direction along...

As in visual perception, information can be selected for prioritized processing at the expense of unattended representations working memory (VWM). However, what is not clear whether and how this prioritization degrades representations. We addressed two hypotheses. First, representational quality items could degraded as a function spatial distance to attended VWM. Second, strength with which an item bound its location To disentangle these possibilities, we designed experiment participants...

What mechanisms underlie the prioritization of neural representations visually perceived information to guide behavior? We assessed dynamics whereby attention biases competition for representation visual stimuli by enhancing relevant and suppressing irrelevant. Multivariate pattern analysis (MVPA) classifiers were trained discriminate patterns fMRI activity associated with each three stimuli, within several predefined ROIs. Participants performed a change-detection task wherein two presented...

This fMRI study aimed at unraveling the neural basis of learning alphabet arithmetic facts, as a proxy transition from slow and effortful procedural counting-based processing to fast effortless it occurs in addition facts. Neural changes were tracked while participants solved problems verification task (e.g., F + 4 = J). Problems repeated across four blocks. Two networks with opposed learning-related identified. Activity network consisting basal ganglia parieto-frontal areas decreased...

Multiplication is thought to be primarily solved via direct retrieval from memory. Two of the main factors known influence multiplication facts are problem size and interference. Because these often intertwined, we sought investigate unique influences interference on both performance neural responses during fact in healthy adults. Behavioral results showed that explained separate portions RT variance, but with significantly stronger contribution size, which contrasts previous work children....
