Background There is significant variability in poststroke locomotor learning that is poorly understood and affects individual responses to rehabilitation interventions. Cognitive abilities relate to upper extremity motor learning in neurologically intact adults, but have not been studied in poststroke locomotor learning. Objective To understand the relationship between locomotor learning and retention and cognition after stroke. Methods Participants with chronic (>6 months) stroke participated in 3 testing sessions. During the first session, participants walked on a treadmill and learned a new walking pattern through visual feedback about their step length. During the second session, participants walked on a treadmill and 24-hour retention was assessed. Physical and cognitive tests, including the Fugl-Meyer-Lower Extremity (FM-LE), Fluid Cognition Composite Score (FCCS) from the NIH Toolbox -Cognition Battery, and Spatial Addition from the Wechsler Memory Scale-IV, were completed in the third session. Two sequential regression models were completed: one with learning and one with retention as the dependent variables. Age, physical impairment (ie, FM-LE), and cognitive measures (ie, FCCS and Spatial Addition) were the independent variables. Results Forty-nine and 34 participants were included in the learning and retention models, respectively. After accounting for age and FM-LE, cognitive measures explained a significant portion of variability in learning ( R2 = 0.17, P = .008; overall model R2 = 0.31, P = .002) and retention (Δ R2 = 0.17, P = .023; overall model R2 = 0.44, P = .002). Conclusions Cognitive abilities appear to be an important factor for understanding locomotor learning and retention after stroke. This has significant implications for incorporating locomotor learning principles into the development of personalized rehabilitation interventions after stroke.

The capacity for humans to learn a new walking pattern has been explored with a split-belt treadmill during single sessions of adaptation, but the split-belt treadmill can also be used to study longer-term motor learning. Although the literature provides some information about motor learning after stroke, existing studies have primarily involved the upper extremity and the results are mixed. The purpose of this study was to characterize learning of a novel locomotor task in stroke survivors. We hypothesized that the presence of neurological dysfunction from stroke would result in slower learning of a locomotor task and decreased retention of what was learned and that these deficits would be related to level of sensorimotor impairment. Sixteen participants with stroke and sixteen neurologically intact participants walked on a split-belt treadmill for 15 min on 5 consecutive days and during a retention test. Step length and limb phase were measured to capture learning of the spatial and temporal aspects of walking. Learning the spatial pattern of split-belt treadmill walking was slowed after stroke compared with neurologically intact subjects, whereas there were no differences between these two groups in learning the temporal pattern. During the retention test, poststroke participants demonstrated equal retention of the split-belt treadmill walking pattern compared with those who were neurologically intact. The results suggest that although stroke survivors are slower to learn a new spatial pattern of gait, if given sufficient time they are able to do so to the same extent as those who are neurologically intact.

In adults, psychiatric disorders are highly comorbid and are negatively associated with cognitive abilities. Individual cognitive measures have been linked with domains of child psychopathology, but the specificity of these associations and the extent to which they reflect shared genetic influences are unknown. In this study we examined the relationship between general factors of cognitive ability ( g) and psychopathology ( p) in early development using two genetically informative samples: the Texas “Tiny” Twin Project (TXtT; N = 626, age range = 0.16–6.31 years) and the Early Childhood Longitudinal Study–Birth Cohort (ECLS-B; N ≈ 1,300 individual twins, age range = 3.7–7.1 years). The total p–g correlation (−.21 in ECLS-B; −.34 in TXtT) was primarily attributable to genetic and shared environmental factors. The early age range of participants indicates that the p–g association is a reflection of overlapping genetic and shared environmental factors that operate in the first years of life.

ABSTRACTThe study explores the relationship between phonological awareness and early reading for bilingual children learning to read in two languages that use different writing systems. Participants were 57 Cantonese–English bilingual 6-year-olds who were learning to read in both languages. The children completed cognitive measures, phonological awareness tasks, and word identification tests in both languages. Once cognitive abilities had been controlled, there was no correlation in word identification ability performance across languages, but the correspondence in phonological awareness measures remained strong. This pattern was confirmed by a principal components analysis and hierarchical regression that demonstrated a different role for each phonological awareness factor in reading performance in each language. The results indicate that phonological awareness depends on a set of cognitive abilities that is applied generally across languages and that early reading depends on a common set of cognitive abilities in conjunction with skills specific to different writing systems.

The Relationship

This study investigated the relationship between suspected neurological impairment (SNI) and cognitive abilities. Performances on cognitive measures administered between 8 mo. and 8 yr. of age were compared employing two different impaired groups and a neurologically normal group. One group demonstrated deviance at Age 1 and neurological normalcy at Age 7 (SNI-1) whereas the other group demonstrated normalcy at Age 1 and neurological deviance at Age 7 (SNI-7). The former evidenced particular difficulty with verbal mental skills, whereas, the latter demonstrated a global pattern of depressed cognitive impairment. However, impairment extended to academic skills at Age 8 for both groups. Deviation was identified at 8 mo. for the former and at 4 yr. for the latter group. The serial use of psychological measures for early screening of the former group was effective, therefore, but more discerning measures are needed to detect subtle deviations which may have existed for one group at Age 7 yr. The need for the identification or development of effective language measures for use with young children was also indicated.

Introduction: The relationship between chronic kidney disease (CKD) and cognitive function remains to be determined. Existing studies focused primarily on estimated glomerular filtration rate (eGFR) but not proteinuria in relation to cognitive function. Hypothesis: In a community-based sample, lower eGFR and presence of proteinuria are cross-sectionally independently associated with lower cognition. Methods: The Shiga Epidemiological Study of Subclinical Atherosclerosis (SESSA) randomly recruited and examined participants from Shiga, Japan in 2006-08 at baseline. Among 824 male participants in the follow-up exam (2010-12), we restricted our analyses to those who underwent the Cognitive Abilities Screening Instrument (CASI), age ≥65 years-old, free of stroke, with no missing pertinent covariates. We calculated eGFR (creatinine-based) according to the 2012-guideline by the Japanese Society of Nephrology. We then divided the participants into three groups by eGFR of ≥60, 59-40, and <40 (mL/min/1.73m 2 ), and separately divided into three groups according to proteinuria using urine dipstick: (-), (-/+), and ≥(1+). We defined CKD as either eGFR <60 or proteinuria ≥ (-/+). In linear regression with CASI score being a dependent variable, we computed the score adjusted for age, highest education attained, smoking, drinking, body mass index, hypertension, diabetes, and dyslipidemia. Results: We analyzed 541 men. The mean [standard deviation] of age and unadjusted score were 72.6 [4.3] years and 89.7 [6.0]. Prevalence of CKD was 56%. The score was significantly lower in participants with CKD than those without it (P=0.03). eGFR and proteinuria categories were separately and jointly associated with lower CASI score in a graded fashion (Ps for trend <0.05 in all the models tested. Table 1 ). Conclusions: Lower eGFR and higher degree of proteinuria were independently associated with lower cognitive function in the community-based men. CKD even in its early phase may predispose to lower cognitive function.

Abstract. The lateral prefrontal cortex (LPFC) plays a major role in both working memory (WM) and response inhibition (RI), which are fundamental for various cognitive abilities. We explored the relationship between these LPFC functions during childhood development by examining the performance of two groups of children in visuospatial and auditory WM tasks and a go/no-go RI task. In the younger children (59 5- and 6-year-olds), performance on the visuospatial WM task correlated significantly with that in the auditory WM task. Furthermore, accuracy in these tasks correlated significantly with performance on the RI task, particularly in the no-go trials. In contrast, there were no significant correlations among those tasks in older children (92 8- and 9-year-olds). These results suggest that functional neural systems for visuospatial WM, auditory WM, and RI, especially those in the LPFC, become fractionated during childhood, thereby enabling more efficient processing of these critical cognitive functions.

Abstract The identification of talent in soccer is critical to various programs. Although many research findings have been presented, there have been only a few attempts to assess their validity. The aim of this study was to determine the relationship between talent and achievement variables in the Vienna Test System. The participants were 91 Czech soccer players, representing four youth soccer teams, who were born in the year 2000. These boys were divided into two groups according to their coaches’ assessments using a TALENT questionnaire. A two-factor model (component 1: “kinetic finesse”; component 2: “mental strength”) was designed to interpret the responses of the coaches on the questionnaire. The Vienna Test System was used to determine the level of players’ cognitive abilities. In total, the subjects performed seven tests in the following order: Raven’s Standard Progressive Matrices (SPM), a reaction test (RT), a determination test (DT), a visual pursuit test (LVT), a Corsi Block-Tapping Test (CORSI), a time/movement anticipation test (ZBA), and a peripheral perception test (PP). To analyze the relationship between talent and achievement variables within the Vienna Test System, correlation analyses were performed. The results revealed that the talented group attained significantly better results on only 1 of the 16 variables, which was ZBA2: movement anticipation - deviation of movement median (r = .217, p = .019). A comparison of the two talent components showed that component 1 (“kinetic finesse”) was a more significant factor than component 2 (“mental strength”). Although we observed statistically significant correlations, their actual significance remains questionable; thus, further research is required.

ABSTRACTIn this article, the literature examining the relationship between testosterone and various cognitive domains in elderly men is reviewed. The review focuses on the role of endogenous testosterone levels and the effects of androgen depletion and replacement. The cognitive domains most commonly linked to testosterone include memory and visuospatial function. Indeed, the literature suggests that in certain conditions (ie, hypogonadism, cognitive impairment) testosterone levels may be significantly associated with memory and visuospatial function, but not other cognitive functions. Studies with larger sample sizes and more sensitive cognitive measures are indicated, as questions remain about the potential role of testosterone as a cognitive enhancer.

Abstract Background: 22q11.2 deletion syndrome (22q11DS) is a common recurrent neurogenetic condition associated with elevated risk for developmental neuropsychiatric disorders and intellectual disability. Children and adults with 22q11DS often exhibit marked social impairment as well as neurocognitive deficits, and have elevated rates of both autism spectrum disorder (ASD) and psychosis. However, the relationship between the basic processes of social cognition and cognitive ability has not been well studied in 22q11DS. Here, we examined differences in social cognition in 22q11DS, relative to multiple groups of idiopathic neuropsychiatric disorders, and typically developing healthy controls (HC). Additionally, we examined differences in intellectual functioning and its relationship to social cognitive abilities. Finally, we examined the relationship between social cognitive abilities and real-world social behavior. Methods: We examined social cognition and intellectual functioning in 273 participants (mean age = 17.74+/-5.18% female = 44.3%): 50 with 22q11DS, 49 youth with first episode psychosis (FEP), 48 at clinical high-risk (CHR) for psychosis, 24 participants with ASD, and 102 HC. Social cognition was assessed using The Awareness of Social Inference Test (TASIT), while reciprocal social behavior was assessed via parent/caregiver ratings on the Social Responsiveness Scale (SRS). Participants were also administered the Wechsler Abbreviated Scale of Intelligence, 2 nd edition (WASI-II) to assess intellectual functioning. Results: The 22q11DS group exhibited significantly lower social cognitive abilities compared to all other groups, even after controlling for intellectual functioning. Significant positive correlations were found between social cognition, as measured by the TASIT, and IQ across groups. In contrast, no significant relationships were found between TASIT and real-world social behavior (SRS) for any group. Conclusions: Our findings indicate social cognitive deficits are more prominent in 22q11DS than idiopathic neuropsychiatric conditions across the age range, even after adjusting for global intellectual function. These results contribute to our understanding of the intellectual and social vulnerabilities of 22q11DS in comparison to idiopathic neuropsychiatric disorders. Our findings of robust associations between intellectual ability and social cognition emphasizes the importance of accounting for neurocognitive deficits in social skills interventions and tailoring these existing treatment models for 22q11DS and other populations with intellectual impairment.
