Full textEvolutionary explanations for geography's influence on complex cognitive ability (CCA) imply virtually immutable components of between-nation IQ differences. Their weight vis-à-vis the weight of situational components was evaluated through an analysis of a 194-country data set. Additive effects of absolute latitude (AL) and longitudinal distance from Homo sapiens' cradle (LDC) explain Northeastern Asian higher, Sub-Saharan African lower CCAs. AL exerts cognitive influence directly and through socioeconomic development and evolutionary genetics whereas LDC does through evolutionary genetics; however, this occurs differently in Africa-Near East- Europe and elsewhere. The findings are understood assuming supremacy of contemporary UVB radiation → hormonal and climatic → socioeconomic mediators of the AL–CCA linkage whose effects are moderated by heterogeneous genetic and cultural adaptations to radiation and climate. Geography's cognitive effects are dynamic and public-policy actions may modify them.

Full textThe main outcomes of this thesis suggest that systemic inflammation may indeed be involved in aetiology of age-related cognitive decline, possibly via neuro-inflammation. Further epidemiological investigation should involve a measurement of biomarkers trajectories in modelling cognitive change. Use of a stronger genetic instrument for inflammatory biomarkers, modeled against cognitive decline rather than cognitive ability as in the current study could further advance knowledge of the bio-pathological mechanisms underlying age-related cognitive decline. Results could ultimately inform subsequent investigations in the form of a randomised control trial, testing an evidence-based anti-inflammatory clinical intervention in diabetic populations as well as the general populations.
Knarr, Abram J. "Do Peripheral HUD Warnings Affect Driving Ability?" Thesis, California State University, Long Beach, 2018. http://pqdtopen.proquest.com/#viewpdf?dispub=10750884.
Full textHeads Up Display (HUD) technologies are being developed to assist drivers and reduce safety hazards. The current study used the Lane Change Task (LCT) and a Peripheral Detection Task (PDT) divided into high and low workload tracks to assess effects of employing a HUD to alert drivers to moving objects in their periphery that are possible hazards. The intent of the current study was to determine whether visual warnings displayed in either color, flashing, or color and flashing formats, would improve detection of moving stimuli without adversely impacting driving ability. Results indicated that the PDT had no significant effect on LCT performance. However, significant main effects of warning format and workload on reaction times, false alarm rates, and sensitivity were obtained. Performance on the PDT task was best when the warnings were non-flashing and yellow, especially in the low workload condition. Explanations of performance on both tasks are discussed.

Full textThe goal of this research was to study differences in cognitive performance on verbal and quantitative measures among subjects of different ages. Data was gathered on subjects ranging in age from 16 to 80 years of age from birth-cohorts from 1927 to 1990. In addition to year of birth, personal characteristics of gender, race/ethnicity and undergraduate area of study were obtained. Multilevel models were built that predict cognitive performance as a function of age, cohort and other non-independent personal characteristics . Verbal performance rises as the age of the test-taker rises; quantitative performance declines as the age of the test-taker rises. After controlling for the race/ethnicity and gender of the test-taker, there are both age and cohort effects for verbal and quantitative models. On the verbal measure, the cohort effect favors those test-takers born at an earlier time. There is an interaction between age and cohort on the quantitative measure. This data is secondary analysis and the records are from those test-takers who choose to take a consequential assessment. When the multilevel models are produced independently for those test-takers ages 20-39 and those ages 40-64, different results are seen between the two age groups. There is little difference in performance for 20-39 year olds on the verbal measure other than a positive effect for age at time of test. For the test-taker aged 40-64, there is a positive effect due to age, a positive cohort effect and a negative interaction effect between age and science study. Comparing the 20-39 year olds with the 40-64 year olds on the quantitative measure, the decline in performance for the older group is one-fourth the rate of decline in the younger group. For the quantitative measure, after controlling for age, there is a positive cohort effect for both age groups.

Full textLes personnes atteintes d'autisme ont des résultats supérieurs au test de perception visuelle ‘cubes' de l'Échelle d'Intelligence de Wechsler en ce qui a trait à la précision et la vitesse d'exécution (Caron et al., 2006). Cette étude avait pour but d'examiner si cette habileté cognitive était d'origine perceptuelle. Vingt participants souffrant d'autisme et 20 enfants non-autistes ont complété le test de cubes sur un écran tactile. L'objectif était de trouver la correspondance entre un cube situé au centre et quatre autres cubes avoisinants. Les attributs visuels de ces cubes étaient manipulés soit au niveau de leur texture, de leur brillance (noir/blanc), ou de leur couleur (rouge/blanc). La cohérence perceptuelle des cubes a été également manipulée de manière à ce que le design des cubes soit à cohérence faible nécessitant une analyse locale accrue par rapport au design à cohérence forte. Les résultats de cette étude ont révélé que la vitesse d'exécution était considérablement plus lente chez les participants autistes lorsque la brillance était manipulée et que le design des cubes était à cohérence faible. En contrepartie, les participants non-autistes ont montré une performance plus précise lorsque la brillance était manipulée et que le design des cubes était à cohérence forte. Cependant, aucune distinction considérable n'a été notée entre les deux groupes lorsque la texture des cubes a été manipulée. Ces résultats suggèrent que les habiletés visuelles et spatiales des individus autistes sont en partie d'origine perceptuelle.

Full textBaker, Christine M. "Effects of bilingualism on working memory ability." Thesis, California State University, Long Beach, 2013. http://pqdtopen.proquest.com/#viewpdf?dispub=1522557.
Full textMuch evidence exists in support of the notion known as a bilingual advantage, the idea that some bilinguals benefit from an executive functioning system superior to monolinguals. The majority of research investigating the bilingual advantage lies in metalinguistic awareness, conflict resolution, and inhibition; however, this thesis examines working-memory abilities by comparing the performance of English monolingual and Spanish-English bilingual groups in a dual task paradigm, taxing lexical retrieval and memory maintenance and manipulation. Participants were asked to perform a lexical retrieval task eliciting high-frequency abstract nouns or adjectives while simultaneously memorizing an accumulating list of target abstract words to be later recalled. Although no difference in immediate recall between language groups was found, bilinguals remembered significantly more target words 5 days after testing. Evidence suggests that bilinguals may build new memory representations that are more resistant to decay than monolingual memory representations.
