Influence of individual differences in temporal sensitivity on timing performance

This research was designed to examine the consistency of individual differences in timing. Subjects were tested initially on a temporal-signal-detection task. In a series of trials, subjects judged whether a stimulus figure was displayed for either 12 s or greater than 12 s. Task performance was used to classify the subjects into groups with high or low temporal sensitivity (d'). Later, the subjects were tested on two classic time-judgment tasks. In a temporal-interference task, subjects reproduced intervals of 8-16 s during which they had rehearsed 0, 3, or 7 digits. Absolute error in time judgments increased linearly as a function of task demands. However, subjects with low temporal sensitivity made more error under all conditions compared with those with high sensitivity. In an isochronous-tapping task, subjects produced a series of 2-s and 5-s intervals. The low-temporal-sensitivity group produced more variable and inaccurate responses than the high-sensitivity group. The results demonstrate cross-situational consistency in timing performance across different tasks, time-judgment methods, and stimulus durations.     

Altering White Racial Identity and Interracial Comfort Through Multicultural Training

The authors examined the impact of multicultural training on the development of White racial identity and interracial comfort. Findings indicated that an integrative multicultural training program resulted in significant increases along 3 dimensions of White racial consciousness and in the levels of interracial comfort. This work extends related efforts to study White racial identity as an important parameter of multicultural training and counseling. In addition, psychometric data and factor structures are provided for the White Racial Consciousness Development Scale (Claney & Parker, 1989) and the Interracial Comfort Index (Claney & Parker, 1989).     

Predictors of Psychosocial and Cognitive Adaptation in Children with Sickle Cell Syndromes

Examined the role of socioecological factors (family functioning and socioeconomic variables) in predicting behavioral and cognitive adaptation in children with sickle cell syndromes (SCD). Participants included 74 African American children and adolescents with SCD and their primary caretakers. Outcomes included internalizing and externalizing behavior symptoms, as rated by caretakers, as well as intellectual abilities and academic achievement, as assessed by individually administered standardized instruments. Family functioning consisted of both caretaker adjustment and family environment (i.e., family adaptability and cohesion). Hierarchical multiple regression analyses revealed that caretaker psychological adjustment predicted externalizing behaviors, while family environment (i.e., adaptability and cohesion) predicted neither behavioral nor cognitive functioning. Socioeconomic variables alone predicted intellectual abilities and academic achievement and also contributed to the prediction of child behavioral adaptation. Results are discussed in terms of relevant sociocultural issues and implications for family-level prevention and intervention.     

Transient global amnesia

Transient global amnesia (TGA) is a memory dysfunction characterized by a sudden onset of dense anterograde amnesia (AA) that gradually resolves across several hours. TGA is typically accompanied by repeated questions (concerning present circumstances) with retrograde amnesia for events preceding the attack, and it usually strikes individuals in their late 50s and early 60s. The etiology of TGA remains unclear, although it probably reflects a temporary disruption of the blood supply to the temporal lobe. The physical and psychological events preceding the attack are diverse, but they often include acute emotional and physical stressors. TGA appears to be benign, with low risk for recurrence or residual complications. While systematic memory research on TGA patients is rare, these individuals present a unique opportunity to study amnestic behaviors in otherwise normal individuals. A guide to conducting future research is provided.

Effects of training in the responsible conduct of research: A survey of graduate students in experimental sciences

In recent years, programs for training in research ethics have become widespread, but very little has been done to assess the effectiveness of this training. Because initial studies have failed to demonstrate a positive impact of research ethics training, this project defined two new outcome variables to be tested in a sample of graduate students at the University of California, San Diego. Trainees were surveyed to assess the role of ethics training in altering their perceptions about their own standards, or their knowledge of options available to them if faced with ethical problems that might arise in conducting and reporting research. In response to a mailing of 505 anonymous questionnaires, 283 replies were received. Similar to previous studies, perceptions of standards were not significantly affected by hours spent in informal discussions about research ethics, in attending courses on research ethics, or in discussions of case studies. However, self-reported knowledge of options for facing research ethics problems was significantly increased in association with increased hours of discussion, class time, or case study discussion. Taken together, this study emphasizes the need for increased attention to the definition and assessment of the goals of research ethics training.     

A reevaluation of semantic versus nonsemantic processing in implicit memory

A number of investigations have purported to demonstrate that semantic processing does not produce a memorial advantage over nonsemantic processing on implicit tests, as contrasted with the typical advantage of semantic over nonsemantic processing on explicit tests. A review of 166 outcomes from 38 studies that have manipulated processing on implicit tests reveals that on 131 occasions (79%), priming was greater following semantic than it was following nonsemantic processing. This difference was found in both perceptual and conceptual implicit memory tests, as well as in within- and between-subjects designs. It suggests that implicit tests reflect the involvement of both conceptual and perceptual processes. Although explicit contamination may account for some of the processing difference in implicit tests, the pervasiveness of the phenomenon, especially in perceptual implicit tests, makes it an unlikely account for the entire effect.     

Research in education: What influence on policy and practice?

This paper is set in a context where increased emphasis is being placed on the “consumer’s” role in research. It discusses the limitations of “knowledge base” approaches, which aim to deliver the findings of educational research to practitioners and policymakers. The tensions between what these consumers expect of research and what it can, in fact, offer are explored, and the conditions under which effective communication can be established are outlined and exemplified. It is argued, however, that the processes of such communication, if they are to establish the necessary engagement of consumers with researchers, will have to take account of the ways in which consumers are motivated and able to acquire new knowledge. In conclusion, it is argued that if the engagement is unsuccessful and the consumers are unconvinced of the value and validity of research findings for policy and practice, then researchers’ ideas will take a back seat in the debate about what is to count as high-quality work that should be funded. The function of research as the critical extension of knowledge may then be replaced by enquiry that comes up with the results the customer wants. Her current research interests are in the relationships among policy, practice and research, teachers’ thinking, provision for children with special educational needs and gender in education. Her best known recent book, with Donald McIntyre, isMaking Sense of Teaching (Open University Press).     

Neuropsychological changes in children with cancer: The treatment of missing data in longitudinal studies

Researchers conducting longitudinal studies with children or adults are inevitably confronted with problems of attrition and missing data. Missing data in longitudinal studies is frequently handled by excluding from analyses those cases for whom data are incomplete. This approach to missing data is not optimal. On the one hand, if data are missing at random, then dropping incomplete cases ignores information collected on those cases that could be used to improve estimates of population parameters (e.g., means, variances, covariances, and growth rates) and improve the power of significance tests of statistical hypotheses. On the other hand, if data are not missing at random, then dropping incomplete cases leads to biased parameter estimates and hypothesis tests that may be internally and externally invalid. This study uses three years of follow-up data from a longitudinal investigation of neuropsychological outcomes of cancer in children to demonstrate the problems presented by missing data in repeated measures designs and some solutions. In evaluating potential biasing effects of attrition, the study extends previous research on neuropsychological outcomes in pediatric cancer by inclusion of patients whose disease had relapsed, and by comparison of surviving and nonsurviving patients. Although the data presented have specific relevance to the study of neuropsychological outcome in pediatric cancer, the problems of missing data and the solutions presented are relevant to a wide variety of diseases and conditions of interest to researchers in child and adult neuropsychology.
