Abstract: Cognitive flexibility has been previously described as the ability to adjust cognitive and behavioral strategies in response to changing contextual demands. Cognitive flexibility is typically assessed via self-report questionnaires and performance on neuropsychological tests in research and clinical practice. A common assumption among researchers and clinicians is that self-report and neuropsychological tests of cognitive flexibility assess the same or similar constructs, but the extent of the relationship between these two assessment approaches in clinical cohorts remains unknown. We undertook a systematic review and meta-analysis to determine the relationship between self-report and neuropsychological tests of cognitive flexibility in clinical s les. We searched 10 databases and relevant gray literature (e.g., other databases and pearling) from inception to October 2020 and used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses reporting guidelines. Eleven articles including 405 participants satisfied our eligibility criteria. A multilevel random-effects meta-analysis revealed no relationship between self-report and neuropsychological tests of cognitive flexibility (0.01, 95% CI [-0.16 to 0.18]). In idual random-effects meta-analyses between 12 different tests pairs also found no relationship. Based on our results, it is clear that the two assessment approaches of cognitive flexibility provide independent information-they do not assess the same construct. These findings have important ramifications for future research and clinical practice-there is a need to reconsider what constructs self-report and neuropsychological tests of "cognitive flexibility" actually assess, and avoid the interchangeable use of these assessments in clinical s les.

Abstract: The capacity to regulate one’s attention in accordance with fluctuating task demands and environmental contexts is an essential feature of adaptive behavior. Although the electrophysiological correlates of attentional processing have been extensively studied in the laboratory, relatively little is known about the way they unfold under more variable, ecologically-valid conditions. Accordingly, this study employed a ‘real-world’ EEG design to investigate how attentional processing varies under increasing cognitive, motor, and environmental demands. Forty-four participants were exposed to an auditory oddball task while (1) sitting in a quiet room inside the lab, (2) walking around a sports field, and (3) wayfinding across a university c us. In each condition, participants were instructed to either count or ignore oddball stimuli. While behavioral performance was similar across the lab and field conditions, oddball count accuracy was significantly reduced in the c us condition. Moreover, event-related potential components (mismatch negativity and P3) elicited in both ‘real-world’ settings differed significantly from those obtained under laboratory conditions. These findings demonstrate the impact of environmental factors on attentional processing during simultaneously-performed motor and cognitive tasks, highlighting the value of incorporating dynamic and unpredictable contexts within naturalistic designs.
