Anxiety and impression formation: Direct information rather than priming explains affect-congruity

Both affect-priming and affect-as-information theories predict that when people are anxious they will form affect-congruent impressions of others, but via different mechanisms. Affect-priming asserts that memory mediates the influence of anxiety on judgement, whereas affect-as-information asserts that people attribute anxiety to the target of judgement. As these theories predicted, anxious participants in Study 1 found an impression-formation target to be more threatening than did control participants. However, this effect was not mediated by memory, and was attenuated in Study 2 when anxious participants attributed their affect to a source other than the target. These findings suggest that anxious people form affect-congruent impressions of others because they attribute their anxiety to the impression-formation target rather than because anxiety primes affect-congruent memory.     

From Sectarian to Secular Control of Education The Case of Newfoundland

On September 2, 1997, Newfoundland transitioned from church to state control over education. Prior to this change, education had been controlled by churches. Recently, on November 9, 2000, an appeal to the Supreme Court of Canada by the Roman Catholic Church to declare the change unconstitutional was denied, settling the issue legally, although, perhaps, not politically. This article describes Newfoundland's educational system prior to the public referendum in 1997 that removed church control of education and explores some of the recent issues that have arisen since transition. It calls for further investigation into the effects of the change and the political, social, and economic forces that led to such a fundamental change.     

THE CHANGING CRITERION DESIGN

This article describes and illustrates with two case studies a relatively novel form of the multiple-baseline design called the changing criterion design. It also presents the design's formal requirements, and suggests target behaviors and circumstances for which the design might be useful.     

Behavior analysis and education: An unfulfilled dream

This paper presents the author's view of why the promise for education visualized by early behavioral researchers is as yet unrealized. It points out that behavior analysis has had an important impact on special education but has had much less influence on teaching practice in regular classrooms. This is not seen as the fault of educators who have failed to embrace procedures developed by behavior analysts. Rather, the author contends, behavior analysts have failed to develop procedures that fit the ecology of the regular classroom. Those developed often require too much additional effort thereby punishing those who attempt their use. Another factor hindering widespread adoption is that behavior analysts have failed to disseminate their procedures and have not participated widely in undergraduate training of teachers. The paper concludes by noting that our success in special education provides a model for behavior analysts interested in regular education. By developing procedures that result in increased academic performance for entire classrooms without punishing the teachers who implement them, by making those procedures available commercially and by publishing in journals teachers read, and finally by participating more widely in undergraduate training, the unfulfilled dream of what behavior analysis has to offer education can be achieved.     

MRI findings in boys with specific language impairment

Magnetic resonance imaging scans of specifically language-impaired (SLI) boys were examined to determine whether atypical cerebral findings could be documented in children whose primary deficits were in language skills. Clinical examination of the scans failed to reveal any visually obvious lesions or abnormalities. In contrast, measurement of the scans revealed atypical perisylvian asymmetries in most of these subjects. The distribution of perisylvian asymmetries in SLI subjects was significantly different from the distribution in controls (p less than .01). Measurement of other brain regions revealed that extraperisylvian areas were occasionally deviant in individual SLI subjects; but no one region was consistently deviant across the SLI group. Thus, only atypical perisylvian asymmetries were linked to the language disorder. These neuroanatomical findings suggest that a prenatal alteration of brain development underlies specific language impairment.     

Repeated assessment of cognition in children and the measurement of performance change.

There is limited understanding of the problems associated with repeated neuropsychological assessment in children, including the statistics used to guide decisions about cognitive change. This study investigated the utility of a computerized assessment battery that was specifically designed for the repeated assessment of cognitive function in children. Eighty-seven participants aged 8 to 12 years completed the battery four times within a 2-hour testing session. The results support the application of this assessment battery for measuring cognitive change in children. A novel method for calculating measurement error is employed, and its use in the detection of cognitive change in individual children is discussed. An estimate of the measurement error within each of the tests is provided, and recommendations are made regarding the application of this assessment battery for measuring cognitive change in children.     

The relationship between HIV disclosure and adjustment

In many cases, sharing the diagnosis of HIV can help people to adjust to their diagnosis. However, several factors may impede this process. A secondary data analysis of 50 HIV-positive adults found that African Americans delayed sharing their diagnosis with others longer than Euro-Americans. In addition, those who perceived more stigma against HIV took longer to tell someone and took longer to adjust to their diagnosis. Implications for practice and research are posited.
