This study identified a sample of children with specific learning disabilities according to Public Law 94-142 criteria. The primary purpose of the study was to examine whether sample member's intravariability of WISC-R subtest scaled scores was related to their reading achievement gain. A second purpose was to determine if any relationship existed between intelligence and reading achievement gain. Eighty-four Resource placed elementary students composed the study sample. They ranged from six to eleven years of age, and were primarily male caucasian. Since 1989, each sample member had been administered the WISC-R once; and , each sample member had been administered the WJTEA-R twice, with at least 12 months separating the two administrations . Results identified no relationship between WSIC-R subtest scaled score scatter and reading achievment gain on the WJTEA-R. A positive correlation was identified be tween intelligence level and academic gains in reading. Important ancillary correlations of significance identified for all subjects included a negative relationship be tween the variable Age and the variables Intelligence , Academic gain, and the WISC-R FD factor . When intelligence was held to within average parameters significant correlations were identified between the variable Achievement and the variables Age and Time (negative), and with the WISC-R FD and VC factors (positive) . Multiple regression analyses indicated the FD factor best able to predict academic gain for this group. It is probable, that in the identification of learning disabled students, that the identification of processing disorders (as with previously sought patterns) is not viable. It may be that the only key characteristics are intellectual level and severe discrepancy.

Syftet med studien var att undersöka eventuella skillnader i grundläggande kognitiva förmågor mellan högpresterande idrottare och amatörer. I denna kvantitativa tvärsnittsstudie samlades datan in från deltagare som rekryterades från ett idrottsgymnasium, en elitklubb och ett antal från personliga kontakter via ett bekvämlighetsurval. 39 deltagare deltog i studien i åldrarna 15-39, 21 högpresterande idrottare (M= 20.48, SD= 5.77) och 18 amatörer (M= 19.44, SD= 4.79). De grundläggande kognitiva förmågorna mättes med fyra kognitiva test: Trail Making Test, The Sustained Attention to Response Task, The Semantic And Phonemic Fluency Test och Digit Symbol Substitution Test. Dessa valdes ut för att mäta uppmärksamhet, bearbetningshastighet och exekutiva funktioner. Resultatet visade en statistisk signifikant skillnad mellan högpresterande idrottare och amatörer i den grundläggande kognitiva förmågan bearbetningshastighet där gruppen av högpresterande idrottare nådde högre värden i mätningarna. Inga signifikanta skillnader uppdagades i de grundläggande kognitiva förmågorna uppmärksamhet och exekutiva funktioner. Studiens resultat indikerar på att framtida forskning bör ta hänsyn till typ av idrott hos atleten i en urvalsprocess för en tydligare jämförelse. Frågan kring skillnader i grundläggande kognitiva förmågor är mer komplex än en uppdelning mellan högpresterande idrottare och amatörer. / The purpose of this study was to investigate possible differences in basic cognitive ability between high-performing and amateur athletes. In this quantitative cross-sectional study the data was collected from participants that were recruited from a highschool, an elite club and through personal contacts. 39 Participants participated in the study ages 15-39, 21 high-performing athletes (M= 20.48, SD= 5.77) and 18 amateur athletes (M=19.44, SD= 4.79). The basic cognitive abilities were measured with four tests: Trail Making Test, The Sustained Attention to Response Task, The Semantic And Phonemic Fluency Test and Digit Symbol Substitution Test. These were selected to measure attention, processing speed, and executive functions. The results showed a statistically significant difference between high-performing athletes and amateur athletes in the basic cognitive ability processing speed where the high-performing athletes showed a higher processing speed than amateur athletes. No significant differences were detected in the basic cognitive abilities of attention and executive functions. The results of the study indicate that future research should take into consideration the type of sport the athlete is involved in for a selection process with a clearer comparison. The differences in basic cognitive abilities is more complex than the comparison between high-performing and amateur athletes.

Abstract The purpose of this master thesis is to conduct a Qualitative analysis on the impact of artificial intelligence (AI) on Telus International, a leading provider of customer service and business process outsourcing solutions using the deductive approach to collect the data. Through interviews with key respondents at the company and a review of relevant literature, this study aims to understand the ways in which artificial intelligence is being used at Telus International in the decision making process and the effects it has on the organisation. The findings of this study suggest that AI has had a positive impact on Telus International, providing the organisation with increased efficiency and productivity. However, the implementation of artificial intelligence has also raised concerns about potential job loss and the need for employees to adapt to new technologies. This study highlights the need for organisations to carefully consider the potential impacts of AI and to provide support for employees during the transition.

Today, many school districts are mandating tests to measure student performance and to hold individual schools and school systems accountable for that performance in order to meet the standards set forth in the No Child Left Behind Act (2001) and the Individuals with Disabilities Education Improvement Act (2004). The focus of this study was to examine the relationship among cognitive ability as measured by the Cognitive Abilities Test (CogAT) and measures of achievement, specifically, standardized achievement scores on the New Jersey Assessment of Skills and Knowledge (NJ ASK) and school grades. The current study investigated archival data of 452 seventh grade students enrolled in a large, suburban public school district during the 2007-2008 school year. Scores on the CogAT and NJ ASK were collected from grades 3, 5, and 7. Final grades in the subject areas of Reading, Writing, Math, Social Studies and Science were collected from report cards from the end of seventh grade of the 2007-2008 school year. Pearson correlations found significant relationships between: (1) cognitive ability and standardized achievement scores in grades 3, 5, and 7, (2) third grade cognitive ability and grade seven grades, and (3) third grade standardized achievement scores and grade seven grades. Further, out of the five cluster scores on the grade 3 CogAT and NJ ASK, the NJ ASK Language Arts score was the best predictor of grades in Reading and Writing and the NJ ASK Mathematics score was the best predictor of grades in Math, Science, and Social Studies. Finally, third grade NJ ASK Language Arts, NJ ASK Mathematics and CogAT Verbal scores were the best predictors of special education classification in grade 7, accounting for a combined 22% of the variance. Limitations to the study and implications for future research and practice are discussed. / School Psychology

The aim of this dissertation was to address a theoretical debate on belief bias. Belief bias is the tendency for people to be influenced by their prior beliefs when engaged in deductive reasoning. Deduction is the act of drawing necessary conclusions from premises which are meant to be assumed as true. Given that the logical validity of an argument is independent of its content, being influenced by your prior beliefs in such content is considered a bias. Traditional theories posit there are two belief bias components. Motivated reasoning is the tendency to reason better for arguments with unbelievable conclusions relative to arguments with believable conclusions. Response bias is the tendency to accept believable arguments and to reject unbelievable arguments. Dube et al. (2010) pointed out critical methodological problems that undermine evidence for traditional theories. Using signal detection theory (SDT), they found evidence for response bias only. We adopted the SDT method to compare the viability of the traditional and the response bias accounts. In Chapter 1 the relevant literature is reviewed. In Chapter 2 four experiments which employed a novel SDT-based forced choice reasoning method are presented, showing evidence compatible with motivated reasoning. In Chapter 3 four experiments which used the receiver operating characteristic (ROC) method are presented. Crucially, cognitive ability turned out to be linked to motivated reasoning. In Chapter 4 three experiments are presented in which we investigated the impact of cognitive ability and analytic cognitive style on belief bias, concluding that cognitive style mediated the effects of cognitive ability on motivated reasoning. In Chapter 5 we discuss our findings in light of a novel individual differences account of belief bias. We conclude that using the appropriate measurement method and taking individual differences into account are two key elements to furthering our understanding of belief bias, human reasoning, and cognitive psychology in general.

The Wide Range Assessment of Memory and Learning (WRAML) is a relatively new instrument used in the assessment of memory in children. The purpose of this study was to examine the validity of the WRAML by comparing the performance of children on both the WRAML and the Woodcock-Johnson Tests of Cognitive Ability- Revised (WJTCA-R). Subjects for the study were children in treatment for a brain tumor at a regional children's medical center. Fifty children participated in the study ranging from ages 6 to 17. A multiple regression analysis was conducted to determine which of four selected clusters from the WJTCA-R would have the highest correlation with the Verbal Memory Index (VERI) from the WRAML. The Short-Term Memory (GSM) cluster had the highest correlation ( r = .82) as predicted. A Pearson's product-moment correlational analysis was conducted between the Visual Processing (GV) cluster from the WJTCA-R and the Visual Memory Index (VISI) from the WRAML. GV was found to have a high positive correlation ( r = .63) with VISI. A similar analysis was conducted between the Long-Term Retrieval (GLR) cluster from the WJTCA-R and the Learning Index (LRNI) from the WRAML. GLR was found to have a high positive correlation ( r = .81) with LRNI. Finally, a correlational analysis was conducted between the Broad Cognitive Ability (BCA) scale from the WJTCA-R and the General Memory Index (GENI) from the WRAML. A high positive correlation ( r = .87) was found between these most global measures from the two batteries. The observed correlation between BCA and GENI was much higher than anticipated. The author concluded that neurological impairment had affected subject memory and intellectual functioning in similar ways. The results do not generalize to children who have not had similar decrements in cognitive functioning. Future research should establish a baseline correlation between the two instruments with a non-impaired population.

International studies speculate that this framework does not only involve deficient cognitive skills, but also well developed, such as creativity. Starting from this hypothesis, the present study aimed to compare the creativity of children with dyslexia (GC) with children without difficulties in reading and writing (GN). It was also investigated how the intelligence is related to that performance in both groups. The GC was recruited at the Clinical Hospital of the State University of Campinas (UNICAMP) and the GN in a regular school of the state of S?o Paulo. It was investigated 13 children in each group, ranging in age from eight years to 11 years and eight months (GC: M=10,92+1,03; GN: M=10,61+0,50), with five females and eight males in group GC and nine females and four males in group GN. To survey the creativity was used the "Test of Figural Creativity for Children (TCFI) and for intelligence was administered the test "Raven Coloured Progressive Matrices (MPCR)", "Human Figure Drawing (DFH)" and "Wechsler Intelligence Scale for Children - third version (WISC-III)", the latter two only in GC. For the selection of the GN was used a questionnaire for parents and a semistructured interview for teachers to eliminate diagnostic criteria for dyslexia, besides the "Academic Performance Test", with the aim of selecting children with reading and writing performance expected for age and grade. The results showed no statistically significant differences between both groups in creativity. However, the GC had a lower average than the GN in the total TCFI, while also showed higher scores for 18 of the 31 characteristics evaluated by it. High correlation was observed between the MPCR and the TCFI in both groups and no significant correlations between the DFH and the WISC-III with the TCFI in GC. Some hypotheses have been formulated: the existence of possible relationships between creativity and executive functions, the latter being to the detriment of individuals with dyslexia, which could explain the result of the total TCFI; the influence of emotional and possibly aspects of personality that are characteristic of dyslexia, which could explain the better performance in the majority of the characteristics evaluated in TCFI. There was no pattern in the correlations between measures of intelligence and creativity in both investigated groups, as found in the literature. It is concluded that this study provided important findings for early clarification on a possible relationship between creativity and dyslexia, however, considering the complexity of both constructs, studies involving the investigation of their relations with other psychological variables as well as expansion and diversification of the sample are needed. / A dislexia ? um transtorno decorrente de disfun??es neuropsicol?gicas e acarreta principalmente dificuldades no aprendizado da leitura. Estudos internacionais especulam que esse quadro n?o somente envolveria habilidades cognitivas deficit?rias, mas tamb?m bem desenvolvidas, como a criatividade. Partindo-se dessa hip?tese, o presente estudo objetivou comparar a criatividade de crian?as com dislexia (GC) com o de crian?as sem dificuldades em leitura e escrita (GN). Tamb?m se investigou a rela??o entre criatividade e intelig?ncia em ambos os grupos. O GC foi recrutado no Hospital de Cl?nicas da Universidade Estadual de Campinas (UNICAMP) e o GN em uma escola de ensino regular de uma cidade do interior de S?o Paulo. Foram investigadas 13 crian?as em cada grupo, com faixa et?ria de oito anos a 11 anos e oito meses (GC: M=10,92+1,03; GN: M=10,61+0,50), sendo cinco do sexo feminino e oito do masculino no GC e nove do sexo feminino e quatro do masculino no GN. Para a avalia??o da criatividade foi utilizado o Teste de Criatividade Figural Infantil (TCFI) e para intelig?ncia foram administrados os testes Matrizes Progressivas Coloridas de Raven (MPCR) , Desenho da Figura Humana (DFH) e Escala de Intelig?ncia Wechsler para crian?as (WISC-III) , sendo os dois ?ltimos somente no GC. Para a sele??o do GN foi utilizado um question?rio para os pais e uma entrevista semiestruturada para os professores a fim de eliminar crit?rios diagn?sticos para dislexia, al?m do Teste de Desempenho Escolar , com o objetivo de selecionar somente aquelas crian?as que apresentassem desempenho em leitura e em escrita esperado para a idade e s?rie. Os resultados encontrados n?o evidenciaram diferen?as estat?sticas significativas entre ambos os grupos na medida de criatividade. No entanto, o GC apresentou menor m?dia em rela??o ao GN no total do TCFI, ao mesmo tempo em que tamb?m apresentou m?dias mais altas em 18 das 31 caracter?sticas avaliadas por esse mesmo teste. Foi verificada alta correla??o entre os testes MPCR e o TCFI em ambos os grupos e correla??es n?o significativas entre o DFH e o WISC-III com o TCFI no GC. Algumas hip?teses foram elaboradas: a exist?ncia de poss?veis rela??es entre criatividade e fun??es executivas, sendo essas ?ltimas em preju?zo em sujeitos com dislexia, que poderia explicar o resultado obtido no total do TCFI; a influ?ncia de aspectos emocionais e possivelmente de personalidade, caracter?sticos a dislexia, que poderiam explicar o melhor desempenho obtido na maioria das caracter?sticas avaliadas no TCFI. N?o foi verificado um padr?o nas correla??es entre as medidas de intelig?ncia e de criatividade em ambos os grupos investigados, assim como encontrado na literatura. Conclui-se que o presente estudo forneceu achados importantes para o in?cio do esclarecimento sobre uma poss?vel rela??o entre criatividade e dislexia, no entanto, considerando a complexidade de ambos os constructos, estudos que envolvam a investiga??o de suas rela??es com outras vari?veis psicol?gicas bem como amplia??o e diversifica??o da amostra se fazem necess?rios.

The distinction between technical and contextual performance is widely recognized in the Industrial/Organization Psychology literature (Sackett & Lievens, 2008). Less well-understood are the causal antecedents of performance in these domains and how those antecedents relate to each other. Motowidlo, Borman, and Schmit (1997) proposed that technical performance is determined largely by cognitive ability, which acts through the mediator technical knowledge to influence technical performance. They also proposed that contextual performance is mainly determined by personality traits and that these traits influence contextual performance via the mediating variable contextual knowledge. Although prior research has examined some of the causal antecedents proposed by Motowidlo et al. (1997), no study has examined these four variables simultaneously, in addition to gathering information about performance criteria in the two domains. This study examined these six variables in a sample of medical students. In keeping with the verbiage used in the medical literature, students' contextual knowledge is referred to as professional knowledge and their contextual performance is referred to as professional performance. Medical students (N = 209) beginning their third year at the University of Texas Medical School at Houston completed measures of professional knowledge and the Big Five personality traits and consented to have their MCAT scores (a proxy for cognitive ability) and their first- and second-year course grades (grade point average; a measure of their technical knowledge) gathered for this investigation. Performance criteria consisted of attending physicians' ratings of students' professional and technical performance during their clinical rotations. Rotations were grouped according to whether they fell into the domain of Primary Care or the Specialties. Notable findings are summarized by a path analytic model. Agreeableness exerted a causal influence on professional knowledge (β = .38) and Primary Care professional performance (β = .14). Extraversion causally affected professional knowledge (β = -.22). Professional knowledge accounted for variance in Primary Care professional (β = .19) and technical performance (β = .22). Openness to experience and conscientiousness influenced technical knowledge (β's -.19 and .25). Cognitive ability was directly related to technical knowledge (β = .43) and Specialties professional (β = -.21) and technical performance (β = -.19). Technical knowledge was related to Primary Care professional (β = .32) and technical performance (β = .42) and also Specialties professional (β = .46) and technical performance (β = .57). Results generally suggest that separate causal paths underlie performance in Primary Care and the Specialties, respectively.
