Perceived Discrimination Among Ethnic Minority Young People: The Role of Psychological Variables1

Because of difficulties in objectively determining discrimination, attention has turned to individual differences in perceptions of discrimination. This study aimed to build on such work by investigating the role of psychological variables in predicting perceived discrimination (PD) in a UK sample of ethnic minority young people (n= 154). A series of multiple regression analyses yielded 3 pathways leading to PD. There was a direct effect of gender on PD. Depression and low self‐esteem and need for approval predicted anxiety, which in turn was related to higher PD. Finally, private collective self‐esteem correlated with public collective self‐esteem, which in turn predicted lower PD. The results point to the importance of psychological variables, both personal and collective, in the perception of ethnic discrimination. Furthermore, the findings enhance our understanding of the complex associations between self‐esteem, affect, and PD.     

Ethical challenges when patients have dementia

Dementia is among the most terrible diseases humans can have. Of all of the things that careproviders could do to enhance the quality of life that persons with dementia have, which ones should they do?     

The genetics of cognitive impairment in schizophrenia: a phenomic perspective

Cognitive impairments are central to schizophrenia and could mark underlying biological dysfunction but efforts to detect genetic associations for schizophrenia or cognitive phenotypes have been disappointing. Phenomics strategies emphasizing simultaneous study of multiple phenotypes across biological scales might help, particularly if the high heritabilities of schizophrenia and cognitive impairments are due to large numbers of genetic variants with small effect. Convergent evidence is reviewed, and a new collaborative knowledgebase - CogGene - is introduced to share data about genetic associations with cognitive phenotypes, and enable users to meta-analyze results interactively. CogGene data demonstrate the need for larger studies with broader representation of cognitive phenotypes. Given that meta-analyses will probably be necessary to detect the small association signals linking the genome and cognitive phenotypes, CogGene or similar applications will be needed to enable collaborative knowledge aggregation and specify true effects.     

From infant to child: the dynamics of cognitive change in the second year of life

The authors review several key areas of early cognitive development in which an abrupt shift in ability at the end of the second year of life has been traditionally assumed. These areas include deferred imitation, self-recognition, language, and categorization. Contrary to much conventional theorizing, the evidence shows robust continuities in all domains of early cognitive development. Where there is evidence of a reorganization of behavior that makes a new level of performance possible, dynamic-systems analyses indicate that even these may be driven by underlying processes that are continuous. Although there remain significant definitional and methodological issues to be resolved, the outcome of this review augers well for newer models in which cognitive development is viewed as a continuous, dynamic process.
