> Abstract:
> Mind wandering is a pervasive feature of human cognition often
> associated with the withdrawal of task-related executive control
> processes. Here, we explore the possibility that, in tasks requiring
> executive control to sustain consistent responding, moments of mind
> wandering could be associated with moments of increased behavioral
> variability. To test this possibility, we developed and administered a
> novel task (the metronome response task) in which participants were
> instructed to respond synchronously (via button presses) with the
> continuous rhythmic presentation of tones. We provide evidence
> (replicated across 2 independent samples) that response variability
> during the 5 trials preceding probe-caught reports of mind wandering
> (tuned-out and zoned-out mind wandering) is significantly greater than
> during the 5 trials preceding reports of on-task performance. These
> results suggest that, at least in some tasks, behavioral variability is
> an online marker of mind wandering.

> magnetic resonance imaging (fMRI), we examined experience-dependent
> functional plasticity in accessing interoceptive representations by

> distraction. In anatomically partitioned analyses of insula activity, MT
> predicted greater IA-related activity in anterior dysgranular insula

> with external context. MT also predicted decreased recruitment of the
> dorsomedial prefrontal cortex (DMPFC) during IA, and altered functional
> connectivity between the DMPFC and the posterior insula, putative
> primary interoceptive cortex. Furthermore, meditation practice
> compliance predicted greater posterior insula and reduced visual pathway
> recruitment during IA. These findings suggest that interoceptive
> training modulates task-specific cortical recruitment, analogous to
> training-related plasticity observed in the external senses. Further,

Research Byte: bIs working memory training effective? A meta-analytic review.

It has been suggested that working memory training programs are effective both as treatments for attention-deficit/hyperactivity disorder (ADHD) and other cognitive disorders in children and as a tool to improve cognitive ability and scholastic attainment in typically developing children and adults. However, effects across studies appear to be variable, and a systematic meta-analytic review was undertaken. To be included in the review, studies had to be randomized controlled trials or quasi-experiments without randomization, have a treatment, and have either a treated group or an untreated control group. Twenty-three studies with 30 group comparisons met the criteria for inclusion. The studies included involved clinical samples and samples of typically developing children and adults. Meta-analyses indicated that the programs produced reliable short-term improvements in working memory skills. For verbal working memory, these near-transfer effects were not sustained at follow-up, whereas for visuospatial working memory, limited evidence suggested that such effects might be maintained. More importantly, there was no convincing evidence of the generalization of working memory training to other skills (nonverbal and verbal ability, inhibitory processes in attention, word decoding, and arithmetic). The authors conclude that memory training programs appear to produce short-term, specific training effects that do not generalize. Possible limitations of the review (including age differences in the samples and the variety of different clinical conditions included) are noted. However, current findings cast doubt on both the clinical relevance of working memory training programs and their utility as methods of enhancing cognitive functioning in typically developing children and healthy adults.
