Oxford cognitive screen: A critical review and independent psychometric evaluation

The Oxford cognitive screen (OCS) is a stroke-specific cognitive screening assessment. Although the test developers have provided psychometric information for the assessment, the OCS has received minimal external scrutiny, with which to triangulate the underpinning psychometrics. The purpose of this study is to provide a critical review and independent validation of the OCS. This study analysed data from an anonymised clinical database, which consisted of 316 patients who were assessed using the OCS on an Acute Stroke Unit. The rates of impairment on tests of memory and receptive communication were lower than expectation, suggesting that these subtests may be relatively insensitive. Patients with aphasia were more likely to be unable to categorised as impaired on non-language tests, suggesting that they remain sensitive to language processing or non-dominant hand usage. Some of the subtests of the OCS achieve high retest reliability, which makes them good candidates for measuring cognitive change over time. Although the OCS has many advantages, it is also important to adequately consider its limitations, that is insensitivity to memory problems, the potential confounding impact of non-dominant hand usage, and the potential that some tests may sample overall cognitive ability instead of domain-specific functioning.     

The Bible in African American Perspectives

This modified “note from the classroom” is a dialogue between two scholars about African American study of the Bible. Bellis introduces the subject by advocating the primacy of social location and the African American student's religious experience in the method that she uses in her classes. (Her sample bibliography, syllabus and course outline for teaching about the Bible in African American perspectives can be found on the Wabash Center web page: http://www.wabashcenter.wabash.edu.) Brown's response takes a different stance with regard to the relative importance for exegesis of historical-critical method and the reader's social location. While Bellis and Brown agree on the appeal that the King James Version holds for many African Americans (but for different reasons), their differing assessments of translations, the distinctiveness of African American interpretations, and the ethnicity of Biblical characters models a lively discussion of issues in teaching and learning.     

Searching for target letters in memory: Individual preferences and instructions for text representation

Participants searched for target letters in a short passage held in memory. In Experiment 1, participants were divided into two groups on the basis of a retrospective report concerning the type of representation used to store the passage in memory, and in Experiment 2, participants were instructed concerning the form of memory representation to use. Only participants using a visual representation missed more targets in the wordthe than in other words. Participants instructed to form a visual representation also made fewer content-word or phrase substitutions when learning the passage than did participants instructed to form an auditory representation. These findings show that choice of memory representation is flexible and that the representation used influences what can be retrieved from memory.     

An assessment of parent involvement in local interagency teams

The results of team members' evaluations of Local Interagency Teams in Vermont are used to assess the participation of parents in one level of the system of care. Active participation in discussions and knowledge of their child's legal rights were consistently highly rated aspects of parent participation. The rating of parents' appearing to feel that they were equal members was consistently low. Attendance at meetings and knowledge of services available showed significant growth over time.     

Avoidant control difficulty and aversive incentive appraisals: Additional evidence of an energization effect

There is evidence that certain physiological and subjective indices of stress are relatively great when control over aversive outcomes is moderately difficult and relatively reduced when control over such outcomes is either easy or impossible. A possible explanation is suggested by Brehm's recent theory of motivation, which asserts that energy mobilization and the perceived unpleasantness of an aversive event will (a) increase with the difficulty of avoidant behavior so long as avoidance is believed to be possible and worthwhile, and (b) be low when avoidant behavior is impossible, not worthwhile, or simply unavailable. This article reports two experiments that examined appraisals of an aversive incentive under conditions where avoidance was expected to be easy, difficult, and impossible. The first demonstrated the complete nonmonotonic pattern of appraisals predicted by the energization theory, something that has proved elusive in previous investigations. The second study demonstrated this as well and, in addition, showed a correspondence between subjects' incentive appraisals and their cardiovascular responses immediately before and during an avoidance task period. Implications and alternative interpretations are discussed.This research was supported in part by a Faculty Research Award from the University of Alabama at Birmingham.     

An examination of the predictive criterion-related validity of professional certification tests

This study examines the predictive criterion-related validity of a series of professional certification tests for water and wastewater management operators. Certification test data were obtained on 164 operators holding one of three jobs in water or wastewater management facilities. The certification test scores were broken down into four component scores and a total score. Criterion data consisted of performance evaluations obtained from the operator's supervisor, a self-rating from the operator, or both. Test scores were correlated with the job performance evaluations. The results indicated that scores on the certification tests were not related to rated job performance by job type, job level, source of performance evaluation, or component of job performance. The findings are discussed in the context of establishing an appropriate criterion against which to validate certification tests, and the practical problems of doing so in an applied setting.
