The effect of vascular health factors on white matter microstructure mediates age-related differences in executive function performance.

Cortex 2021 May 25;141:403-420. Epub 2021 May 25.

The University of Texas at Dallas, School of Behavioral and Brain Sciences, Center for Vital Longevity, Dallas, TX, USA. Electronic address:

Even within healthy aging, vascular risk factors can detrimentally influence cognition, with executive functions (EF) particularly vulnerable. Fronto-parietal white matter (WM) connectivity in part, supports EF and may be particularly sensitive to vascular risk. Here, we utilized structural equation modeling in 184 healthy adults (aged 20-94 years of age) to test the hypotheses that: 1) fronto-parietal WM microstructure mediates age effects on EF; 2) higher blood pressure (BP) and white matter hyperintensity (WMH) burden influences this association.

Switching Gears: A Self-Regulatory Approach and Measure of Nonwork Role Re-Engagement Following After-Hours Work Intrusions.

J Bus Psychol 2021 Jun 9:1-17. Epub 2021 Jun 9.

BetterUp, 1200 Folsom Street, San Francisco, CA 94103 USA.

As employees' personal lives are increasingly splintered by work demands, the boundary between work and nonwork domains is becoming ever more blurred. Grounded within a self-regulatory approach and the executive control function of inhibitory control, we operationalize and examine nonwork role re-engagement (NWRR)-the extent to which individuals can redirect attentional resources back to nonwork tasks following work-related intrusions. In phases 1 and 2, we develop and refine a psychometrically sound unidimensional measure for NWRR aligned with the self-regulatory processes of self-control and interference control underlying inhibitory control.

Why Does Cognitive Training Yield Inconsistent Benefits? A Meta-Analysis of Individual Differences in Baseline Cognitive Abilities and Training Outcomes.

Front Psychol 2021 26;12:662139. Epub 2021 May 26.

Cognition in Context Lab, Department of Psychology and Center for Mind & Brain, University of California, Davis, Davis, CA, United States.

Despite growing interest in improving cognitive abilities across the lifespan through training, the benefits of cognitive training are inconsistent. One powerful contributor may be that individuals arrive at interventions with different baseline levels of the cognitive skill being trained. Some evidence suggests poor performers benefit the most from cognitive training, showing compensation for their weak abilities, while other evidence suggests that high performers benefit most, experiencing a magnification of their abilities.

Post-Intensive Care Syndrome (PICS) in Older People.

Ann Geriatr Med Res 2021 Jun 14. Epub 2021 Jun 14.

Geriatrics and Palliative Unit, Department of Internal Medicine, Raja Isteri Pengiran Anak Saleha (RIPAS) Hospital, Brunei Darussalam.

The increasing survival rate from the intensive care unit (ICU) has led to the recognition that survivors may develop long-term impairments in terms of cognitive, psychiatric and physical domains. This post-ICU syndrome (PICS) as well as the debilitating effects on family members (PICS-F) is usually under-recognised by clinicians. In this paper, two cases of PICS illustrate the different impairments that may occur in ICU survivors. Read More

Linking inhibitory control to math achievement via comparison of conflicting decimal numbers.

Cognition 2021 Jun 11;214:104767. Epub 2021 Jun 11.

Department of Psychology, Rutgers University, Newark, USA; Behavioral Neural Sciences Graduate Program, Rutgers University, Newark, USA. Electronic address:

The relationship between executive functions (EF) and academic achievement is well-established, but leveraging this insight to improve educational outcomes remains elusive. Here, we propose a framework for relating the role of specific EF on specific precursor skills that support later academic learning. Starting from the premise that executive functions contribute to general math skills both directly - supporting the execution of problem solving strategies - and indirectly - supporting the acquisition of precursor mathematical content, we hypothesize that the contribution of domain-general EF capacities to precursor skills that support later learning can help explain relations between EF and overall math skills.

Early life adversity predicts brain-gut alterations associated with increased stress and mood.

Neurobiol Stress 2021 Nov 25;15:100348. Epub 2021 May 25.

G. Oppenheimer Center for Neurobiology of Stress and Resilience, University of California, Los Angeles, USA.

Alterations in the brain-gut system have been implicated in various disease states, but little is known about how early-life adversity (ELA) impacts development and adult health as mediated by brain-gut interactions. We hypothesize that ELA disrupts components of the brain-gut system, thereby increasing susceptibility to disordered mood. In a sample of 128 healthy adult participants, a history of ELA and current stress, depression, and anxiety were assessed using validated questionnaires. Read More

Emotional Assessment in Spanish Youths With Antisocial Behavior.

Front Psychol 2021 25;12:671851. Epub 2021 May 25.

Department of Psychology, Center for Health Research, University of Almería, Almería, Spain.

Impaired emotional capacity in antisocial populations is a well-known reality. Taking the dimensional approach to the study of emotion, emotions are perceived as a disposition to action; they emerge from arousal of the appetitive or aversive system, and result in subjective, behavioral, and physiological responses that are modulated by the dimensions of valence, arousal, and dominance. This study uses the International Affective Picture System (IAPS) to study the interaction between the type of picture presented (pleasant, neutral, or unpleasant) and group (adolescents under custody in juvenile justice centers, adolescents under non-custodial measures, and secondary school students) in the emotional assessment of these dimensions.

Executive Functions of Swedish Counterterror Intervention Unit Applicants and Police Officer Trainees Evaluated With Design Fluency Test.

Front Psychol 2021 11;12:580463. Epub 2021 May 11.

Department of Clinical Neuroscience, Karolinska Institutet, Stockholm, Sweden.

Executive functions (EF) represent higher order top-down mechanisms regulating information processing. While suboptimal EF have been studied in various patient groups, their impact on successful behavior is still not well described. Previously, it has been suggested that design fluency (DF)-a test including several simultaneous EF components mainly related to fluency, cognitive flexibility, and creativity-predicts successful behavior in a quickly changing environment where fast and dynamic adaptions are required, such as ball sports.
