“…Studies investigating the neurobiological level might be able to resolve which underlying mechanism leads to CIE. However, current studies point into different mechanisms of either prefrontal (Shewokis et al, 2016) or parietal (Thürer et al, 2017) brain areas and require further examination.…”

Positive effects of variable practice conditions on subsequent motor memory consolidation and generalization are widely accepted and described as the contextual interference effect (CIE). However, the general benefits of CIE are low and these benefits might even depend on decreased retest performances in the blocked-practicing control group, caused by retroactive inhibition. The aim of this study was to investigate if CIE represents a true learning phenomenon or possibly reflects confounding effects of retroactive inhibition. We tested 48 healthy human participants adapting their reaching movements to three different force field magnitudes. Subjects practiced the force fields in either a Blocked (B), Random (R), or Constant (C) schedule. In addition, subjects of the Blocked group performed either a retest schedule that did (Blocked-Matched; BM) or did not (Blocked-Unmatched; BU) control for retroactive inhibition. Results showed that retroactive inhibition did not affect the results of the BU group much and that the Random group showed a better consolidation performance compared to both Blocked groups. However, compared to the Constant group, the Random group showed only slight benefits in its memory consolidation of the mean performance across all force field magnitudes and no benefits in absolute performance values. This indicates that CIE reflects a true motor learning phenomenon, which is independent of retroactive inhibition. However, random practice is not always beneficial over constant practice.

“…They found patterns of cortical activation consistent with the known pattern of early training activity expansion and late training activity pruning. Many functional mapping studies used near infrared spectroscopy (NIRS) focusing on prefrontal cortex, probably reflecting attentional control rather than aspects of sensorimotor control (Andreu-Perez et al, 2016;Leff et al, 2008;Ohuchida et al, 2009;Shewokis et al, 2017). The limited brain coverage and spatial resolution of NIRS precluded the investigation of especially relevant sensorimotor networks.…”

“…Cognitive load theory offers an additional interpretation of the relationship between FPC and DLPFC activity and motor performance. [18][19][20] If FPC and DLPFC strongly reflect the intrinsic load in the current task, we could expect that relatively higher activity in these regions is observed under a nonoptimal attentional condition. However, contrary to this expectation, individuals who were good at directing their attention to body movements (i.e., the IF-dominant subgroup) showed higher activity under the IF condition.…”

“…Alternatively, the current findings suggest that relatively higher activity in the FPC and DLPFC under the IF condition reflects germane load, contributing to improved motor performance. 19 In other words, encouraging the assignment of a cognitive resource to the germane load might be a fundamental benefit of an individual's optimal attentional strategy during motor tasks.…”

“…16,17 Specifically, previous studies have reported that the prefrontal cortex is related to intrinsic load, which depends on individual skills or task difficulty as well as germane load, which involves the construction of schemas that contribute to learning enhancement. [18][19][20] Furthermore, the cognitive ability based on limited capacity, as described above, can change with age and educational background and is reflected as neural activity in the prefrontal cortex. 21,22 Thus, evaluating prefrontal activity is a reasonable approach for characterizing individual differences in cognitive neural processes.…”

Prefrontal activity predicts individual differences in optimal attentional strategy for preventing motor performance decline: a functional near-infrared spectroscopy study

Directing attention to movement outcomes (external focus; EF), not body movements (internal focus; IF), is a better cognitive strategy for motor performance. However, EF is not effective in some healthy individuals or stroke patients. We aimed to identify the neurological basis reflecting the individual optimal attentional strategy using functional near-infrared spectroscopy. Sixty-four participants (23 healthy young, 23 healthy elderly, and 18 acute stroke) performed a reaching movement task under IF and EF conditions. Of these, 13 healthy young participants, 11 healthy elderly participants, and 6 stroke patients showed better motor performance under EF conditions (EF-dominant), whereas the others showed IF-dominance. We then measured prefrontal activity during rhythmic hand movements under both attentional conditions. IF-dominant participants showed significantly higher left prefrontal activity than EF-dominant participants under IF condition. In addition, receiver operating characteristic analysis supported that the higher activity in the left frontopolar and dorsolateral prefrontal cortices could detect IF-dominance as an individual's optimal attentional strategy for preventing motor performance decline. Taken together, these results suggest that prefrontal activity during motor tasks reflects an individual's ability to process internal body information, thereby conferring IF-dominance. These findings could be applied for the development of individually optimized rehabilitation programs.
