A lack of demographic information and data related to the achievement of short-term goals during substance abuse treatment among persons who are deaf or hard of hearing dictated the need for the study. New York State maintains a database on all individuals who participate in treatment. Within this database, 1.8% of persons in treatment for substance use disorder (SUD) were also deaf or hard of hearing. As hypothesized, members of the deaf and hard of hearing sample were older, likelier to be white, and likelier to be female, relative to the SUD-only group. For both groups, alcohol, heroin, and cocaine had the highest rates of reported use. Achievement of short-term goals in the areas of alcohol use, drug use, vocational/educational goals, and overall goals indicated no differences between the deaf and hard of hearing group and the SUD-only group. Implications of these findings are discussed. 相似文献

This study examined the effect of exemplar typicality on reaction time and accuracy of categorization. High-functioning children (age 9-12), adolescents (age 13-16), and adults with autism (age 17-48) and matched controls were tested in a category verification procedure. All groups showed improved processing throughout the lifespan for typical and somewhat typical category exemplars. However, individuals with autism responded more slowly than matched controls to atypical exemplars at all ages. The results are discussed in terms of potential differences in the type of processing that may be required for categorizing typical and atypical category exemplars. Parallels are also drawn to the results of previous studies on face processing in individuals with autism. 相似文献

The purpose of this paper is to explore the tensions that erupted between the two authors during the final stages of their engagement with the practical argument process. These tensions arose when the 'researcher' constructed a representation of 'the teacher's' reality. In this paper, the researcher shares her representation and the teacher responds to her analysis. The teacher's response to the researcher's representation of her and her teaching suggests tensions arose between the teacher and the researcher over how the researcher constructed the teacher's practical argument. As the teacher and the researchers, we analyze our experiences with the practical argument process and our collaborative relationship. The result is an enlarged view of the place of story and practical argument within research collaborations. In addition, we learned the necessity of continuing dialog between researcher and teacher through the writing of the project. This ensures that, regardless of the research method, both collaborators are heard and their tales are told in the public representation. 相似文献

Gestalt psychology principles of figure‐ground segregation, symmetry, closure, proximity, good continuation, and similarity provide a simple yet powerful analytic vocabulary for discussing page layout and graphics. The six principles apply readily to typography, white space, data tables and maps, the relation between graphics and text, and other facets of textual design. The principles explain many difficulties that readers have in processing texts and graphics, and they explain why well‐designed pages and graphics are effective. 相似文献

Individuals in eight different types of administrative positions in two‐year colleges were asked to rate the importance of a variety of external and internal issues in the next five years. The purpose of the study reported here was first to identify those internal and external issues that administrators viewed as being of high importance. A second purpose was to assess the degree of consensus among differing types of administrative positions. The third objective was to identify differences between public and independent two‐year college, between men and women, and minority and white administrators perceptions of issues identified as being most important. There was a high degree of agreement across administrative groups as to the importance of five external issues; and when asked to indicate the two most critical issues, administrators were almost unanimous in their assessment. There is less agreement on the two critical internal issues. Some differences by gender and racial/ethnic group were noted, but the differences were not as great as might have been expected. 相似文献
