A Study of Black and White College Women

In an examination of career aspirations, 101 black and 530 white college women were asked to indicate their occupational and educational plans, important considerations for career choices, and their attitudes toward combining the roles of career and family. Results indicated that women who planned careers in male-dominated occupations had higher career and educational aspirations than women who desired careers in femaledominated occupations. Black women who planned careers in male-dominated professions showed high levels of aspirations, planned more education than was necessary for the desired occupations, and perceived less conflict in combining the roles of career and family than their white counterparts. There were few differences between black and white women in their attitudes toward the traditional roles of men and women. Those choosing female-dominated careers, however, had more traditional attitudes regardless of race. Implications of these findings for the influence of occupational gender dominance on career aspirations are discussed.     

Augmenting Data With Published Results in Bayesian Linear Regression

In most research, linear regression analyses are performed without taking into account published results (i.e., reported summary statistics) of similar previous studies. Although the prior density in Bayesian linear regression could accommodate such prior knowledge, formal models for doing so are absent from the literature. The goal of this article is therefore to develop a Bayesian model in which a linear regression analysis on current data is augmented with the reported regression coefficients (and standard errors) of previous studies. Two versions of this model are presented. The first version incorporates previous studies through the prior density and is applicable when the current and all previous studies are exchangeable. The second version models all studies in a hierarchical structure and is applicable when studies are not exchangeable. Both versions of the model are assessed using simulation studies. Performance for each in estimating the regression coefficients is consistently superior to using current data alone and is close to that of an equivalent model that uses the data from previous studies rather than reported regression coefficients. Overall the results show that augmenting data with results from previous studies is viable and yields significant improvements in the parameter estimation.     

Evaluative conditioning: Overview and further options

Abstract

The demonstration of evaluative conditioning by Baeyens, Eelen, and Van den Bergh confirms our previous findings and extends the evidential basis for conditioning without awareness. The case made against their findings by Shanks and Dickinson is not supported by the methodological claims they advance. We suggest alternative control procedures and argue that evaluative conditioning plays an adaptive role in the formation of preferences.     

The relation between pointing and language development: A meta-analysis

The use of the pointing gesture is one of the first ways to communicate with the world. This gesture emerges before the second year of life and it is assumed to be the first form of intentional communication. This meta-analysis examined the concurrent and longitudinal relation between pointing and the emergence of language. Twenty-five studies were included into the meta-analysis, including 734 children. The role of several moderators was examined: pointing modality, pointing motive, age at which the pointing was measured, the assessment method of the pointing gesture and language development, the modality of language, SES, and country. The results showed both a concurrent (r = .52) and a longitudinal (r = .35) relation between pointing and language development. The relation between pointing and language development became stronger with age, and was found for pointing with a declarative and general motive, but not for pointing with an imperative motive. It is concluded that the pointing gesture is a key joint-attention behavior involved in the acquisition of language.     

Defensive and offensive behaviours in a Kleefstra syndrome mouse model

Animal Cognition - Kleefstra syndrome in humans is characterized by a general delay in development, intellectual disability and autistic features. The mouse model of this disease (Ehmt1±)...     

Visuospatial working memory for locations,colours, and binding in typically developing children and in children with dyslexia and non‐verbal learning disability

This study examined forward and backward recall of locations and colours and the binding of locations and colours, comparing typically developing children – aged between 8 and 10 years – with two different groups of children of the same age with learning disabilities (dyslexia in one group, non‐verbal learning disability [NLD] in the other). Results showed that groups with learning disabilities had different visuospatial working memory problems and that children with NLD had particular difficulties in the backward recall of locations. The differences between the groups disappeared, however, when locations and colours were bound together. It was concluded that specific processes may be involved in children in the binding and backward recall of different types of information, as they are not simply the resultant of combining the single processes needed to recall single features.
