Executive functions and writing skills in children with and without ADHD.
Conclusion: These findings suggest multiple pathways to writing skill difficulties in children with ADHD, while suggesting that their overt behavioral symptoms may be less involved in their writing difficulties than their underlying neurocognitive vulnerabilities.

Heterogeneity of effects of cognitive reserve on performance in probable Alzheimer’s disease and in subjective cognitive decline.
Conclusions : Different proxies may reflect different compensatory mechanisms of CR depending on task demand and on an individual’s global cognitive condition. In particular, while the Education proxy can capture CR-related cognitive compensation in a pathological condition such as probable AD, the more complex Life experience proxy might be useful for capturing CR-related effects when signs of deterioration are subtle, like in SCD.

The ERP correlate of episodic recollection is a neurocognitive determinant of subjective memory complaints: Implications on their predictive validity.
Conclusions: SMCs are partially determined by malfunctioning of the hippocampal relational memory system. In line with this, SMCs predict performance in objective memory tests if they also target hippocampally dependent processes. The study emphasizes the prognostic relevance of SMCs as episodic memory decline is an important preclinical marker for the development of Alzheimer’s Disease (AD).

Cross-cultural comparison of MMSE and RUDAS in German and Turkish patients with Alzheimer’s disease.
Conclusions: The findings highlight the need to consider the educational background, linguistic integration of older non-Western immigrants for the objective characterization of cognitive profiles. The results provide support for the use of the RUDAS, particularly, among older Turkish immigrants with lower educational levels and varying degrees of acculturation, bilingualism.

The relationship of cogniphobia to performance validity and symptom validity in neuropsychological assessment.
Conclusions: Cogniphobia, especially the avoidance of cognitive exertion component, is associated with performance in the invalid range on both PVTs and SVTs and is also related to report of somatic concerns when controlling for beliefs that cognitive exertion is dangerous.

Higher self-reported posttraumatic stress symptoms are associated with poorer working memory in active-duty service members.
Objective: Posttraumatic stress is a significant issue facing military service members and can negatively impact working memory (WM), which is critical for performance success. Yet, few studies have examined the link between self-reported posttraumatic stress symptoms (PTSS) and WM performance in active-duty military cohorts. The present study utilized hierarchical linear modeling to examine this relationship by considering PTSS and underlying symptom clusters as well as WM demands related to load and affective interference in an active-duty military cohort (N = 515). Method: PTSS severity was assessed via the posttraumati...

Processing rhythm in speech and music: Shared mechanisms and implications for developmental speech and language disorders.
Conclusion: The current framework can be used as a basis to investigate potential links between observed timing deficits in developmental disorders, impairments in the proposed mechanisms, and pathology-specific deficits which can be targeted in treatment and training supporting speech therapy outcomes. On these grounds, we propose future research directions and discuss implications of our framework. (PsycInfo Database Record (c) 2021 APA, all rights reserved) (Source: Neuropsychology)

Longitudinal association of intraindividual variability with cognitive decline and dementia: A meta-analysis.
Conclusion: Cognitive IIV, including both IIV-I and IIV-D operationalizations, appears to be associated with subsequent cognitive decline and/or dementia and may offer a novel indicator of incipient dementia in both clinical and research settings.

Poor sleep quality is associated with greater negative consequences for cognitive control function and psychological health after mild traumatic brain injury than after orthopedic injury.
Conclusions: Our findings show that poor sleep quality has a more negative impact on cognitive control function and psychological outcome in patients with mTBI, compared to trauma controls. This indicates an increased vulnerability to poor sleep quality in patients who have suffered an mTBI. (PsycInfo Database Record (c) 2021 APA, all rights reserved) (Source: Neuropsychology)

"Evidence for a robust, estradiol-associated sex difference in narrative-writing fluency": Correction.
Conclusions: When verbal fluency is assessed through narrative writing, a robust female advantage becomes evident. It is associated with the reproductive life stage and variations in current estradiol concentrations, particularly in individuals prenatally exposed to relatively more estradiol than testosterone.

Motor control and learning in individuals with early-treated phenylketonuria.
Conclusions: Motor learning is adversely affected in individuals with ETPKU. Further investigation into the behavioral and neural mechanisms of motor learning in ETPKU will advance our understanding of the etiologic basis for this disruption as well as how it relates to the broader neurocognitive profile of ETPKU.

The effects of mood and cognition on daily functioning and quality of life in older people living with HIV and people with Parkinson’s disease.
Conclusions: Mood symptoms contribute significantly to poor ADLs and QOL in people aging with chronic diseases such as long-term HIV infection and PD. Comprehensive assessment and treatment of mood symptoms are recommended for ensuring optimal functional independence and life quality.

Implicit learning of perceptual sequences is preserved in Parkinson’s disease.
In this study, we investigated implicit sequence learning independently from motor sequence learning in individuals with PD. To this end, we used a perceptual SRT-task that did not rely upon sequential motor knowledge. Method: We measured response times (RTs) of 19 participants with PD (Hoehn & Yahr II or III; mean age 65) and 18 age-matched healthy controls (HC; mean age 61.5) in a perceptual SRT-task. General learning effects and sequence-specific learning effects were analyzed using repeated measures ANOVAs. Results: A significant decreasing linear trend (p (Source: Neuropsychology)

Greater time in bed and less physical activity associate with poorer cognitive functioning performance in Huntington’s disease.
Conclusions: Sleep timing and physical activity relate to cognitive functioning in HD and may be important targets for management in behavioral intervention studies aimed at improving cognition in HD. (PsycInfo Database Record (c) 2021 APA, all rights reserved) (Source: Neuropsychology)

The latent factor structure underlying regional brain volume change and its relation to cognitive change in older adults.
Conclusions: The current results suggest that brain change across 27 bilateral regions of interest can be grouped into five change factors, three of which (global gray matter, temporolimbic, and medial temporal lobe atrophy) are strongly associated with cognitive decline.
