Purpose This study compared the performance of South Asian and White adults on the Behavioural Assessment of the Dysexecutive Syndrome (BADS; Wilson, Alderman, Burgess, Emslie, & Evans, 1996) and the Functional Assessment of Verbal Reasoning and Executive Strategies (FAVRES; MacDonald, 2005), tests that can be used by speech-language pathologists to assess executive function (EF). Method Twenty South Asian and 20 White participants were administered the BADS and FAVRES. Raw scores were converted to profile scores on the BADS and to standard scores on the FAVRES. Analysis of covariance statistics were calculated to compare EF test performance. Results South Asian and White participants did not demonstrate significant performance differences on the BADS. On the FAVRES, Whites had significantly higher accuracy scores on 2 of the 4 subtests and significantly higher rationale scores on 3 subtests. South Asian adults who completed all of their formal education in India had lower accuracy and rationale scores on 2 of the 4 subtests versus South Asian adults who completed at least some of their formal education in North America. No significant differences occurred on the Time scores for any subtest or on the overall Reasoning score. Conclusions Performance differences on EF tests may exist between South Asian and White adults. Further research is necessary to determine the impact of cultural and linguistic differences on EF test performance in South Asian adults.

The Peabody Picture Vocabulary Test (PPVT) is a widely used test of receptive vocabulary, but no researchers to date have examined the performance of low-educated, low-literate L2 adults, or compared these individuals’ performances to their more highly educated peers. In this study, we used many-facet Rasch analysis and mixed-effects linear regression to determine the impact of educational background and other demographic variables on PPVT test performance. The analyses rely on the performance data of 1014 adult learners of Dutch as a second language on the Dutch version of the PPVT (PPVT-III-NL). The results show that a substantial proportion of score variance can be attributed to educational background variables and to the educational tracks the participants followed. These tracks, which cater to the needs of different L2 learner profiles, appear to exacerbate rather than mediate any performance differences. Although this study provides evidence of performance differences and differential item functioning resulting from linguistic, demographic, and educational variables, it offers no data to invalidate the use of the PPVT on low-educated L2 adults.

2004 Background: RTOG 0825 evaluated overall survival (OS) and progression-free survival (PFS) differences in patients with newly diagnosed GBM treated with standard chemoradiation, maintenance temozolomide and placebo (Arm 1) or bevacizumab (Arm 2). While OS was equivalent, PFS was longer in Arm 2. Longitudinal NCF testing was performed to evaluate clinical benefit. Methods: NCF was evaluatedat baseline and while on study and progression free with the Hopkins Verbal Learning Test-Revised (HVLT-R), Trail Making Test (TMT) and Controlled Oral Word Association (COWA). Change in NCF from baseline was categorized using the reliable change index. Differences between treatment arms were compared at follow-up evaluations. Additionally, baseline (B) and early changes (EC) (B to week 10) in NCF were examined as prognostic factors. Results: 542 patients consented and 507 randomized patients participated, with test completion rates at weeks 0 (B), 10, 22, and 34 of 94-97, 69-73, 59-64, and 53-58%, respectively. Mean test performance at B was equivalent between arms and ranged from -0.8 to -4.8 SDs below healthy population norms with global NCF on a composite variable at -2.0 SDs. There were no statistically significant between arm differences in frequency of improvement through week 34. Decline on COWA (verbal measure of executive function) at week 34 relative to baseline was more common (16.1 vs 5.7%) in patients in Arm 1 (p<0.05); whereas, there were trends for more decline in Arm 2 on a visuomotor measure of executive function (TMT B, p< 0.06; 22.2 vs 35.4%). B performance and EC in global NCF, memory, executive function and processing speed were prognostic for OS. At B, global NCF was prognostic for PFS. EC in global NCF, memory and executive function were prognostic for PFS. Conclusions: There was a statistically significant difference in the frequency of decline on a verbal test of executive function at week 34 favoring Arm 2. However, this was not found at earlier time points and was not found on a visuomotor test of executive function. B and EC in NCF were prognostic for OS and PFS. Longitudinal modeling is ongoing to further evaluate the impact of treatment on patients’ NCF. Support: U10 CA21661, U10 CA37422 and Genentech, Inc. Clinical trial information: NCI-2009-01670.

Summary: Vocabulary tests, part of most test batteries of general intellectual ability, measure both verbal and general ability. Newly developed techniques for confirmatory factor analysis of dichotomous variables make it possible to analyze the influence of different abilities on the performance on each item. In the testing procedure of the Computerized Swedish Enlistment test battery, eight different subtests of a new vocabulary test were given randomly to subsamples of a representative sample of 18-year-old male conscripts (N = 9001). Three central dimensions of a hierarchical model of intellectual abilities, general (G), verbal (Gc'), and spatial ability (Gv') were estimated under different assumptions of the nature of the data. In addition to an ordinary analysis of covariance matrices, assuming linearity of relations, the item variables were treated as categorical variables in the Mplus program. All eight subtests fit the hierarchical model, and the items were found to load about equally on G and Gc'. The results also indicate that if nonlinearity is not taken into account, the G loadings for the easy items are underestimated. These items, moreover, appear to be better measures of G than the difficult ones. The practical utility of the outcome for item selection and the theoretical implications for the question of the origin of verbal ability are discussed.

This paper examines the impact of community education and challenges facing Centres for Education and Community Action as a rural development strategy in Cameroon. The study was conducted in the North-West Region of Cameroon, employing field observations, semi-structured interviews with key informants using a convenient sampling technique and through elaborate review of documents. These research instruments were blended into what is termed triangulation and the data collected was analysed descriptively. The main focus of qualitative analysis is to understand the ways in which people act and the accounts that people give for their actions. This paper posits that extreme dependence on the provision of Western formal education cannot solve the problems of a rapidly changing society like Cameroon, which is facing a long-term economic crisis and persistent unemployment issues of graduates. Consequently, education should be redefined in the context of the prevailing economic crisis to make it responsive to the aspirations of rural communities. Findings showed that community education had contributed towards rural development immensely but has suffered many challenges due to neglect of the field in the policy agenda. This paper recommends the integration of community education with formal education to facilitate group and community betterment in particular and rural transformation in general.

Deaf and hard of hearing (DHH) children have been claimed to lag behind their hearing peers in various domains of cognitive development, especially in implicit learning, executive function, and working memory. Two major accounts of these deficits have been proposed: one based on a lack of auditory access, and one based on a lack of language access. This chapter reviews these theories in relation to the available evidence and concludes that there is little evidence of direct effects of diminished auditory access on cognitive development that could not also be explained by diminished language access. Specifically, reports of deficits in implicit learning are not broadly replicable. Some differences in executive function do stem from deafness itself but are not necessarily deficits. Where clinically relevant deficits in executive function are observed, they are inconsistent with the predictions of accounts based on auditory access, but consistent with accounts based on language access. Deaf–hearing differences on verbal working memory tasks may indicate problems with perception and/or language, rather than with working memory. Deaf–hearing differences on nonverbal tasks are more consistent with accounts based on language access, but much more study is needed in this area. The chapter concludes by considering the implications of these findings for psychological theory and for clinical/educational practice and by identifying high-priority targets for future research.

Abstract Objective The happy–sad task adapts the classic day–night task by incorporating two early acquired emotional concepts (“happy” and “sad”) and demonstrates elevated inhibitory demands for native speakers. The task holds promise as a new executive function measure for assessing inhibitory control across the lifespan, but no studies have examined the influence of language of test administration on performance. Method Seventy adult native English speakers and 50 non-native speakers completed the computerized day–night and the new happy–sad tasks administered in English. In two conditions, participants were categorized pictorial stimuli either in a congruent manner (“happy” for a happy face) or in a more challenging, incongruent manner (“sad” for a happy face). Lexical decision performance was obtained to estimate levels of English language proficiency. Results Native speakers and non-native speakers performed comparably except for the critical incongruent condition of the happy–sad task, where native speakers responded more slowly. A greater congruency effect for the happy–sad task was found for native than for non-native speakers. Lexical decision performance was associated with performance on the challenging incongruent conditions. Conclusion This study reinforced the usefulness of the happy–sad task as a new measure in evaluating inhibitory control in adult native-speakers. However, the language of test administration needs to be considered in assessment because it may lead to performance differences between native and non-native speakers.

AbstractThis paper presents a comprehensive evaluation of data pre-processing and word embedding techniques in the context of Arabic document classification in the domain of health-related communication on social media. We evaluate 26 text pre-processings applied to Arabic tweets within the process of training a classifier to identify health-related tweets. For this task we use the (traditional) machine learning classifiers KNN, SVM, Multinomial NB and Logistic Regression. Furthermore, we report experimental results with the deep learning architectures BLSTM and CNN for the same text classification problem. Since word embeddings are more typically used as the input layer in deep networks, in the deep learning experiments we evaluate several state-of-the-art pre-trained word embeddings with the same text pre-processing applied. To achieve these goals, we use two data sets: one for both training and testing, and another for testing the generality of our models only. Our results point to the conclusion that only four out of the 26 pre-processings improve the classification accuracy significantly. For the first data set of Arabic tweets, we found that Mazajak CBOW pre-trained word embeddings as the input to a BLSTM deep network led to the most accurate classifier with F1 score of 89.7%. For the second data set, Mazajak Skip-Gram pre-trained word embeddings as the input to BLSTM led to the most accurate model with F1 score of 75.2% and accuracy of 90.7% compared to F1 score of 90.8% achieved by Mazajak CBOW for the same architecture but with lower accuracy of 70.89%. Our results also show that the performance of the best of the traditional classifier we trained is comparable to the deep learning methods on the first dataset, but significantly worse on the second dataset.

Abstract The coronavirus disease 2019 (COVID-19) pandemic has had a profound impact on medical educational curricula. We aimed to examine the impact of these unprecedented changes on the formal education of paediatric cardiology fellows through a nationwide survey. A REDCap™-based voluntary anonymous survey was sent to all current paediatric cardiology fellows in the United States of America in May, 2020. Of 143 respondents, 121 were categorical fellows, representing over one-fourth of all categorical paediatric cardiology fellows in the United States of America. Nearly all (140/143, 97.9%) respondents utilised online learning during the pandemic, with 134 (93.7%) reporting an increase in use compared to pre-pandemic. The percentage of respondents reporting curriculum supplementation with outside lectures increased from 11.9 to 88.8% during the pandemic. Respondents considered online learning to be “equally or more effective” than in-person lectures in convenience (133/142, 93.7%), improving fellow attendance (132/142, 93.0%), improving non-fellow attendance (126/143, 88.1%), and meeting individual learning needs (101/143, 70.6%). The pandemic positively affected the lecture curriculum of 83 respondents (58.0%), with 35 (24.5%) reporting no change and 25 (17.5%) reporting a negative effect. A positive effect was most noted by those whose programmes utilised supplemental outside lectures (62.2 versus 25.0%, p = 0.004) and those whose lecture frequency did not decrease (65.1 versus 5.9%, p < 0.001). Restrictions imposed by the COVID-19 pandemic have greatly increased utilisation of online learning platforms by medical training programmes. This survey reveals that an online lecture curriculum, despite inherent obstacles, offers advantages that may mitigate some negative consequences of the pandemic on fellowship education.

One of the most studied aspects of children’s cognitive development is that of the development of the executive function, and research has shown that physical activity has been demonstrated as a key factor in its enhancement. This meta-analysis aims to assess the impact of specific sports interventions on the executive function of children and teenagers. A systematic review was carried out on 1 November 2020 to search for published scientific evidence that analysed different sports programs that possibly affected executive function in students. Longitudinal studies, which assessed the effects of sports interventions on subjects between 6 and 18 years old, were identified through a systematic search of the four principal electronic databases: Web of Science, PubMed, Scopus, and EBSCO. A total of eight studies, with 424 subjects overall, met the inclusion criteria and were classified based on one or more of the following categories: working memory, inhibitory control, and cognitive flexibility. The random-effects model for meta-analyses was performed with RevMan version 5.3 to facilitate the analysis of the studies. Large effect sizes were found in all categories: working memory (ES −1.25; 95% CI −1.70; −0.79; p < 0.0001); inhibitory control (ES −1.30; 95% CI −1.98; −0.63; p < 0.00001); and cognitive flexibility (ES −1.52; 95% CI −2.20; −0.83; p < 0.00001). Our analysis concluded that healthy children and teenagers should be encouraged to practice sports in order to improve their executive function at every stage of their development.
