The Nature and Consequences of Essentialist Beliefs About Race in Early Childhood

It is widely believed that race divides the world into biologically distinct kinds of people—an essentialist belief inconsistent with reality. Essentialist views of race have been described as early emerging, but this study found that young children (n = 203, M_age = 5.45) hold only the more limited belief that the physical feature of skin color is inherited and stable. Overall, children rejected the causal essentialist view that behavioral and psychological characteristics are constrained by an inherited racial essence. Although average levels of children's causal essentialist beliefs about race were low, variation in these beliefs was related to children's own group membership, exposure to diversity, as well as children's own social attitudes.     

Psychological evaluation of specific learning disorders

Conclusion The diagnosis of specific learning disorders is a complex undertaking that requires the examination of a number of psychological dimensions. The “learning disabilities” label has often been abused and is frequently used to explain a wide range of school and behavior problems with little understanding of the criteria necessary for differential diagnosis. A complete evaluation for learning disabilities must assess cultural, structural, and emotional variables as well as intellectual functioning and academic achievement. Examination of the functional integrity of the various perceptual processes, including visual, auditory and kinesthetic modalities, is necessary, The clinician must establish that a delay in achievement does actually exist and that poor school performance is not a result of poor motivation or an unwillingness to demonstrate acquired skills. If a significant delay is found in the acquisition of secondary language symbol skills, then the examiner is pressed to determine which specific psychological, perceptual-associational, memory, or motor deficits are responsible for the learning disorder. This paper was presented at the 28th Annual Conference of The Orton Society in Dallas, Texas, November 1977.     

Building Bridges in Teacher Education: Creating Partnerships With Parents

This study investigated the learning experiences, outcomes, and perceptions of graduate students in a collaboration and consultation course focusing on parent-professional partnerships. The course was designed as a teacher preparation model that envisions teachers, school psychologists, and families learning together to build effective partnerships to better student outcomes. Nineteen graduate students seeking a degree in special education or school psychology were provided multiple opportunities to engage in experiences with parents of children with disabilities, including having parents embedded in the course for the entire semester. Data were collected utilizing multiple methods and included a family/professional partnership survey and focus group discussions conducted both pre- and post-course, as well as a Learning Objectives and Activities Survey. Analyses of qualitative and quantitative data indicate a change in students' knowledge, beliefs, dispositions, and experiences of parent-professional partnerships.     

Governing knowledge in the scientific community: Exploring the role of retractions in biomedicine

Although the validity of knowledge is critical to scientific progress, substantial concerns exist regarding the governance of knowledge production. While research errors are as relevant to the knowledge economy as defects are to the manufacturing economy, mechanisms to identify and signal “defective” or false knowledge are poorly understood. In this paper, we investigate one such institution - the system of scientific retractions. We analyze the universe of peer-reviewed scientific articles retracted from the biomedical literature between 1972-2006 and comparing with a matched control sample in order to identify the correlates, timing, and causal impact of scientific retractions. This effort provides insight into the workings of a distributed, peer-based system for the governance of validity in scientific knowledge. Our findings suggest that attention is a key predictor of retraction - retracted articles arise most frequently among highly-cited articles. The retraction system is expeditious in uncovering knowledge that is ever determined to be false (the mean time to retraction is less than two years) and democratic (retraction is not systematically affected by author prominence). Lastly, retraction causes an immediate, severe, and long-lived decline in future citations. Conditional on the obvious limitation that we cannot measure the absolute amount of false science in circulation, these results support the view that distributed governance systems can be designed to uncover false knowledge relatively swiftly and to mitigate the costs that false knowledge for future generations of producers.     

Children's Understanding of Knowledge Acquisition: The Tendency for Children to Report That They Have Always Known What They Have Just Learned

Children's attention to knowledge-acquisition events was examined in 4 experiments in which children were taught novel facts and subsequently asked how long they had known the new information. In Experiment 1, 4- and 5-year-olds tended to claim they had known novel animal facts for a long time and also reported that other children would know the novel facts. This finding was replicated in Experiment 2, using facts associated with chemistry demonstrations. In Experiments 3 and 4, children were taught new color words. 5-year-olds, but not 4-year-olds, distinguished between novel and familiar color words, reporting they had not known the novel words before the test session, but they had always known the familiar words. 4-year-olds in Experiment 4 were better able to distinguish novel and familiar color words when the teaching of the novel words was an explicit and salient part of the procedure.
