Language and communication development in Down syndrome

Although there is considerable variability, most individuals with Down syndrome have mental retardation and speech and language deficits, particularly in language production and syntax and poor speech intelligibility. This article describes research findings in the language and communication development of individuals with Down syndrome, first briefly describing the physical and cognitive phenotype of Down syndrome, and two communication related domains-hearing and oral motor skills. Next, we describe language development in Down syndrome, focusing on communication behaviors in the prelinguistic period, then the development of language in children and adolescents, and finally language development in adults and the aging period. We describe language development in individuals with Down syndrome across four domains: phonology, semantics, syntax, and pragmatics. Wethen suggest strategies for intervention and directions for research relating to individuals with Down syndrome.     

Intentional and identity processes: A social constructionist investigation using student journals

In contrast to traditional theories of career development that focus on decision-making processes in relation to market work, [Richardson, M. S. (2004). The emergence of new intentions in subjective experience: A social/personal constructionist and relational understanding. Journal of Vocational Behavior, 64, 485-498], informed by social constructionism and considering both work and relationships, suggests that the process of emerging intentional states or intentional process is central to the broader task of constructing a life. This study was designed to investigate this process. The research situation consisted of three structured group discussions with students in a graduate class. Journals written after the group discussions constituted the data for the study. Based on the first stage of data analysis, the scope of investigation was expanded to include emerging identity states or identity process and the emotional experience of the group discussions. In the second phase of data analysis, intentional process and identity process data were analyzed for themes and the emotional experience data were coded. Results of both phases of data analysis are discussed in relation to future research and implications for practice.

Cognitive competencies and aggressive behavior: A developmental study

A number of studies have demonstrated that increased socially related cognitive skills are associated with decreases in aggressive behavior. However, the link between aggression and intelligence or academic skills is less evident. While some research indicates that poor academic performance is related to aggression, it is unclear which components of intellectual ability and performance are critical to the management of aggressive behaviors. In two independent longitudinal studies of elementary school-age children, the relationship among several aspects of cognitive competence and several aspects of aggressive behavior were examined. The results of the first study showed that aggressive behavior observed in kindergarten children was more closely related to academic performance in the first and second grades than to general cognitive ability (IQ). The results of the second study, a comprehensive three-year investigation of upper elementary school-age children, indicated that teachers' assessments of aggression and parents' ratings of cruelty were consistent over time for boys, but not for girls. The intercorrelations among aggression measures within each of the three years also revealed stable sex differences. Boys identified as aggressive in the classroom were more likely to be perceived as aggressive, cruel, and/or delinquent at home, but for girls, there was little correlation between aggression at school and in the home. The analyses relating measures of cognitive functioning to indices of aggressive behavior made clear the importance of discriminating among various facets of these psychological constructs. IQ had a negligible relationship with aggression and a weak inverse relationship to delinquency. An overall index of cognitive functioning was a somewhat more consistent negative correlate of aggression, cruelty, and delinquency, especially for boys. A similar pattern was found for the correlates of academic performance. Academic disability was strongly related to delinquency in boys, and to a lesser degree to aggression in boys. Of the several cognitively related factors that were explored, Low Need Achievement manifested the strongest and most consistent relationships with the different facets of aggression and antisocial behavior, especially in boys. The implications of these results for psychological interventions in the school are discussed.     

Structures And Structuralism In Contemporary Philosophy Of Mathematics

In recent philosophy of mathematics avariety of writers have presented ``structuralist'views and arguments. There are, however, a number ofsubstantive differences in what their proponents take``structuralism' to be. In this paper we make explicitthese differences, as well as some underlyingsimilarities and common roots. We thus identifysystematically and in detail, several main variants ofstructuralism, including some not often recognized assuch. As a result the relations between thesevariants, and between the respective problems theyface, become manifest. Throughout our focus is onsemantic and metaphysical issues, including what is orcould be meant by ``structure' in this connection.     

Decision responsibility, task responsibility, identifiability, and social loafing

Two laboratory experiments were conducted. Results of the first experiment revealed that identifiability had no impact on the degree of cognitive loafing when group members were asked to make a decision. Identifiability did have an impact when group members were asked to express an opinion. The second experiment replicated findings of the first experiment and, in addition, indicated that unidentifiable individuals with sole task responsibility loafed more than unidentifiable individuals who shared task responsibility. Cognitive effort was measured through recall of stimulus material.
