Competition and Instructional Set Effects On the Speed and Accuracy of a Throwing Task

Abstract

Two experiments were conducted to investigate the effects of competition and instructional sets on the speed and accuracy of a dart-throwing task. In both experiments individuals competed against another subject on one day, and performed under noncompetitive conditions on a second day. The five distinct instructional sets varied from extreme emphasis on speed to extreme emphasis on accuracy. Multivariate analyses of variance revealed main effects for instructional sets on speed and accuracy in both experiments. Strong tradeoffs occurred with speed slowing and accuracy improving as the instructional emphasis changed from speed to accuracy. A competition by instructional sets interaction in Experiment 2 indicated that competition facilitated speed when speed was important, but when instructions emphasized accuracy, speed was slower in competition than in noncompetition. Accuracy was not affected by competition.     

Characteristic behaviour orientations of young scientists: A comparison between young mathematicians/physicists and other natural scientists

Methods of sociological enquiry using data on qualifications, performance indicators, conditions for research and social background were used to investigate aspects of behaviour in young natural scientists relevant to research careers. It was shown that mathematicians and physicists were essentially more intrinsically motivated than the other cadres in the fields of natural sciences and that this manifested itself in a high intensity of work and a greater involvement in activities.     

The Protection of a Statement? Permanent exclusions and the SEN Code of Practice

The number of pupils with Statements who are permanently excluded from school has been identified as an issue in several national studies. This paper reports on a small-scale research project within one local education authority (LEA), aimed at identifying common factors and issues around the exclusion of Statemented pupils from mainstream schools. Key findings include a high rate of significant literacy and numeracy difficulties in the sample, limited communication between some schools and LEA support services, the schools' predominant use of Statements to provide in-class support from a learning support assistant rather than other more targeted interventions, and teachers' perceptions that no amount of increased funding through the Statement would have prevented the exclusion.     

Developmental Trajectories in Children With and Without Autism Spectrum Disorders: The First 3 Years

Retrospective studies indicate 2 major classes of autism spectrum disorder (ASD) onset: early and later, after a period of relatively healthy development. This prospective, longitudinal study examined social, language, and motor trajectories in 235 children with and without a sibling with autism, ages 6–36 months. Children were grouped as: ASD identified by 14 months, ASD identified after 14 months, and no ASD. Despite groups' initial similar developmental level at 6 months, ASD groups exhibited atypical trajectories thereafter. Impairment from 14 to 24 months was greater in the Early‐ASD than the Later‐ASD group, but comparable at 36 months. Developmental plateau and regression occurred in some children with ASD, regardless of timing of ASD diagnosis. Findings indicate a preclinical phase of varying duration for ASD.     

The pursuit of excellence or the search for intimacy? The forced‐choice dilemma of gifted youth

Educators often fail to recognize that the intellectually gifted differ from their age peers in their social and emotional development as much as in their intellectual and academic characteristics. A dilemma peculiar to gifted youth arises through the interaction of the psychosocial drives towards intimacy and achievement, which complement each other in students of average ability, but which place the gifted student in a forced‐choice situation. If the gifted child chooses to satisfy the drive for excellence he or she must risk forfeiting the attainment of intimacy with age peers; if the choice is intimacy, the gifted may be forced into a pattern of systematic and deliberate underachievement to retain membership in the social group. Homogeneous grouping of gifted students is suggested as a partial solution to this dilemma.     

INTERGENERATIONAL DAYCARE AND PRESCHOOLERS' ATTITUDES ABOUT AGING

The evidence that intergenerational contact influences children's attitudes about the elderly or aging, in either a positive or negative manner, is mixed. In an attempt to shed light on this issue, perceptions of the elderly were assessed for 33 3-to 5- year-old children enrolled in either an intergenerational daycare program or a daycare program without an intergenerational curriculum. The Children's Attitudes Toward the Elderly (CATE) and a measure of perceived ability to participate in activities (Activity Scale) were used to examine the influence of an intergenerational daycare program on preschool children's attitudes. Program-related differences in attitudes about aging or the elderly were expected, but, overall, the two groups were very similar. In general, children rated older adults less positively than they did younger adults, and they believed that older adults could participate in fewer activities than children could. Longitudinal studies of intergenerational programs, especially programs with an aging education curriculum, are needed to further illuminate the effects of intergenerational contact on children's attitudes.     

Attaining information literacy: An investigation of the relationship between skill level,self-estimates of skill,and library anxiety

Competency theory predicts a miscalibration between students' self-assessments of their information literacy skills and their actual skill level. This study investigates whether such a disparity is evident among incoming freshmen who test as non-proficient on a standardized test of information literacy. In addition, this study analyzes Information Literacy Test scores and library anxiety test scores to provide preliminary data on whether library anxiety is related to information literacy skill attainment. Findings reveal that the relationship between information literacy skills and self-assessments predicted by competency theory are evident in the domain of information literacy. This study did not find an association between information literacy skill scores and total library anxiety scores. However, a significant negative correlation between information literacy scores and the subscale “knowledge of the library” indicates that as information literacy scores rise, anxiety scores related to a lack of knowledge of the library fall. The findings suggest that traditional information literacy instruction may not be effective with non-proficient students, who are unlikely to see themselves as needing or benefiting from such instruction.
