Measurement fidelity of clinical assessment methods in a global study on identifying reproducible brain signatures of obsessive–compulsive disorder.
Conclusions: It is feasible to achieve measurement fidelity of clinical measures in multisite, multilinguistic global studies, despite the challenges inherent to such endeavors. Future studies should not only report IRR but also consider reporting methods of standardization of data collection and measurement invariance to identify factor structures of core clinical measures.

Past and future episodic detail retrieval is reduced among clinically normal older adults at higher genetic risk for late-onset Alzheimer’s disease.
Conclusions: These findings suggest that APOE4 is associated with a selective reduction of episodic detail during past and future autobiographical thinking among clinically normal older adults. Reduced episodic detail generation, therefore, may be an early cognitive associate of higher risk for Alzheimer’s disease dementia.

Examination of bidirectional associations between neurocognitive functioning and housing stability in homeless adults: A longitudinal subgroup analysis of the at Home/Chez Soi study.
Conclusions: These results suggest verbal learning and memory functioning is a key contributor to housing stability among homeless adults with serious mental illness. This work has important implications for health services that support individuals transitioning into stable housing and for the attainment of long-term functional independence.

Executive (dys)functions and ODD and CD: A systematic review and meta-analysis.
Neuropsychology, Vol 37(2), Feb 2023, 133-156; doi:10.1037/neu0000881Objective: Precursors of antisocial behavior in children may be associated with neuropsychological deficits, namely in executive functions (EF). The main objective of this systematic review and meta-analysis was to synthesize evidence of the relation between EF performance and early manifestations of antisocial behavior in children and adolescents. Method: The procedures of this systematic review and meta-analysis were based on the PRISMA recommendations. The review was based on a systematic search in the EBSCOhost and Pubmed databases. Fifty studies were...

A systematic review and meta-analysis of factors influencing ImPACT concussion testing in high school and collegiate athletes with self-reported ADHD and/or LD.
Conclusions: These results provide the first quantitative synthesis of the literature in this area. It is recommended that future research further examines these topics in athletes with LD and co-occurring ADHD/LD (given the focus on ADHD), as well as the effects that all of these conditions may have on concussion recovery and return-to-play decision-making.

The associations of childhood psychosocial factors with cognitive function in midlife—The young finns study.
Conclusions: The findings suggest an association of childhood psychosocial factors with midlife learning ability and memory. If these links are causal, the results highlight the importance of a child’s self-regulation and social adjustment as plausible determinants for adulthood cognitive health.

The dementia apraxia test can detect early-onset Alzheimer’s disease.
Conclusions: DATE is an accurate tool for detecting early-onset AD within 2 years of symptom onset. The diagnostic cutoff point should be higher for middle-aged populations than for late-onset AD. (PsycInfo Database Record (c) 2023 APA, all rights reserved) (Source: Neuropsychology)

Locations of objects are better remembered than their identities in naturalistic scenes: An eye-tracking experiment in mild cognitive impairment.
Conclusions: Locations of objects are better remembered than their identities; memory for changes is best when involving both features. These mechanisms are spared by pathological ageing as indicated by the similarity between groups besides trivial differences in overall performance. These findings demonstrate that VWM mechanisms in the context of naturalistic scene information are preserved in people with MCI.

Do demographic factors influence detection of invalid neuropsychological test performance using common performance validity tests? A multisite investigation.
Conclusion: Most demographic factors evaluated accounted for relatively little variance in individual PVT performance and did not significantly predict overall validity categorization. Compensation-seeking status correlated with validity classification across both groups, but offers limited diagnostic utility itself compared to objective PVT scores. Premorbid IQ within the AMC group demonstrated influence on particular PVTs (i.e., RDS) reflecting the difficulty of assessing validity within low IQ populations, particularly with PVTs more strongly correlated with IQ.

Effort during prolonged wakefulness is associated with performance to attentional and executive tasks but not with cortical excitability in late-middle-aged healthy individuals.
Conclusion: In healthy late-middle-aged individuals, more effort is perceived to perform cognitive tasks, but it is not sufficient to overcome the performance decline brought by lack of sleep. Entry in the seventh decade may stand as a turning point in the daily variations of perceived effort and its link with cognition.

Varying failure criteria on performance validity tests influences interpretation of cognitive outcomes.
Conclusions: Methods of defining PVT failure can greatly influence differences in cognitive function between groups defined by PTS symptom levels. Findings highlight the importance of considering performance validity when interpreting cognitive data and warrant future investigation of PVT failure criteria in other conditions.
