Neurocognitive Tasks

BACKGROUND In recent years, there has been an increased interest in the development of remote psychological assessment. These platforms increase accessibility and allow clinicians to monitor important health metrics thereby informing patient-centered treatment. OBJECTIVE Here we report on the properties and usability of a new web-based neurocognitive assessment battery and present a normative dataset for future use. METHODS Seven hundred eighty-one participants completed a portion of 8 tasks which captured performance in auditory processing, visual-spatial working memory, visual-spatial learning, cognitive flexibility, and emotional processing. A subset of individuals (n=195) completed a five-question survey measuring the acceptability of the tasks. RESULTS Between 252 and 426 participants completed each task. Younger individuals outperformed their older counterparts on 6 of the 8 tasks. Therefore, central tendency data metrics were presented by seven different age bins. The broad majority of participants found the tasks interesting, enjoyable and endorsed some interest in playing them at home. Less than one percent of individuals endorsed not at all for the statement: I understood the instructions. Older individuals were more likely to understand the instructions to a lower extent; however, 72 percent of individuals over the age of 60 still felt that they understood the instructions at the level of mostly or very much. CONCLUSIONS Overall, the tasks were found to be widely acceptable to participants. Use of web-based neurocognitive tasks such as these may increase the ability to deploy precise data informed interventions to a wider population.

And Mathematics

Recent research has pointed to two possible causes of mathematical (dis-)ability: working memory and number sense, although only few studies have compared the relations between working memory and mathematics and between number sense and mathematics. In this study, both constructs were studied in relation to mathematics in general, and to mathematical learning disabilities (MLD) in particular. The sample consisted of 154 children aged between 6 and 10 years, including 26 children with MLD. Children performing low on either number sense or visual-spatial working memory scored lower on math tests than children without such a weakness. Children with a double weakness scored the lowest. These results confirm the important role of both visual-spatial working memory and number sense in mathematical development.

Predictors Of Academic Achievement

Objective: To identify common and shared predictors of academic achievement across samples of children with ADHD. Method: Two clinically referred samples from New Zealand (1 n = 88, 82% boys; 2 n = 121, 79% boys) and two community samples from the United States (3 n = 111, 65% boys; 4 n = 114, 69% boys), completed similar diagnostic, cognitive and academic assessments. Hierarchical multiple regression analyses identified significant predictors of word reading, spelling, and math computation performance in each sample. Results: Entered after IQ, semantic language, age at testing, and verbal working memory emerged as consistent predictors of achievement across academic subjects and samples. Visual-spatial working memory contributed to variance in math performance only. Symptom severity explained limited variance. Conclusions: We recommend evaluations of children with ADHD incorporate assessments of working memory and language skills. Classroom/academic interventions should accommodate reduced working memory and address any identified language weaknesses.

Measurement invariance of the Wechsler Intelligence Scale for Children, Fifth Edition (WISC-V) 10 subtest primary battery was evaluated across sex, age (6–8, 9–11, 12–14, and 15–16 year-olds), and three diagnostic (attention-deficit/hyperactivity disorder, anxiety, and encephalopathy) groups within a large clinical sample ( N = 5359) referred to a children’s specialty hospital. Competing models were tested using confirmatory factor analysis (CFA), and a five-factor oblique model corresponding to the publisher’s hypothesized first-order measurement model (e.g., verbal comprehension, fluid reasoning, visual-spatial, working memory, and processing speed) was found to have the best model fit. Multigroup CFA was subsequently used to evaluate progressively more restrictive constraints on the measurement model. Results indicated that full metric invariance was attained across the three groups studied. Full scalar invariance was attained for sex and diagnostic groups. Partial scalar invariance was attained for age-group. The results of this study provide support for the first-order scoring structure of the five WISC-V factors in the 10 subtest primary battery with this large clinical sample.

The purpose of the research was to find a relationship between selected cognitive functions and anxiety in relation to the quality of life in subjective assessment in schizophrenic patients. the study encompassed a group of patients hospitalized and continuing the treatment after the hospitalization in an outpatient setting. the battery of cognitive neuropsychological tests used to assess cognitive functions included: trail making test, and Stroop test. the intensity of anxiety as state and trait was assessed with the Spielberger State-Trait Anxiety Inventory (STAI).The patients were also requested to fill in the Life Quality Scale questionnaire and the questionnaire of the Frankfort Scale of mental and physical state. the results were analyzed statistically. In the examined group statistically significant relation was found between the results of measuring psychomotor speed, visual-spatial working memory, as well as intensity of anxiety as trait in a group of patients who have a negative opinion about the quality of their life. the correlation between negative opinion only about contacts with friends or eating meals was found in the group with anxiety as trait-was not found among the patients with psychomotor disruption. the above correlations between cognitive and executive tests results show how important are that interactions in the process of constructing a good rehabilitation program for patients with schizophrenia.

Purpose Based on evidence of deficits in domain-general cognitive abilities associated with developmental language disorder (DLD), the current study examined sustained attention performance in children with DLD compared to children with typical language development (TLD) and the interrelations between visual–spatial sustained attention, visual–spatial working memory, and language abilities across groups. Method Participants included 67 children at 7 years of age: 25 children with DLD (13 girls and 12 boys) and 42 children with TLD (23 girls and 19 boys). We assessed children's visual–spatial sustained attention, visual–spatial working memory, and language ability on a test of narrative language. Result Children with DLD scored significantly below their peers on a measure of visual–spatial sustained attention. Significant intercorrelations were observed between sustained attention, working memory, and language ability within the DLD group, but no correlations were observed between these measures in the TLD group. Conclusion Children with DLD have domain-general deficits in sustained attention, and correlational results have implications for whether and how language abilities are supported by domain-general cognition in both typical and disordered development.

Oculomotor Activity

Microsaccade rates and directions were monitored while observers performed a visual working memory task at varying retinal eccentricities. We show that microsaccades generate no interference in a working memory task, indicating that spatial working memory is at least partially insulated from oculomotor activity. Intervening tasks during the memory interval affected microsaccade patterns; microsaccade frequency was consistently higher during concurrent spatial tapping (no visual component) than during exposure to dynamic visual noise (no task). Average microsaccade rate peaked after appearance of a fixation cross at the start of a trial, and dipped at cue onset and offset, consistent with previous results. Direction of stimuli in choice tasks did not influence microsaccade direction,however.
