Increasing Safety Belt Use: Effects of Modeling and Trip Length1

Effects of modeling on car safety belt use were investigated in a field experiment. Modeling, anticipated trip length, and gender of the model were manipulated in a 2 × 2 × 2 factorial design. Sixty-four female college students were told that they were to participate in an experiment that would take place in another location, requiring a drive either of less than one mile or of several miles. The driver either used or did not use a safety belt. Subjects' belt use was significantly related to the model's behavior. When the driver used a safety belt, 77.4% of the subjects used one; when the driver did not use a safety belt, only 313% of the subjects used one. A significant effect for trip length was also found. In the long trip condition, 71.9% of the subjects used a belt; in the short trip condition, 35.5% used one. Results are interpreted as support for a social learning theory approach to increasing voluntary safety belt use.     

An intrahemispheric integration deficit in dyslexia

In order to investigate the hypothesis that dyslexia may result from a failure of intrahemispheric integration between auditory-verbal and visual-verbal processing, a dichotic listening task and a parallel divided visual field task were administered to a group of dyslexic boys between the ages of 8 and 11 years, and a group of normal control subjects individually matched for age and WISC intelligence. The dyslexics were on average over two years retarded in reading and spelling. Dyslexics exhibited a normal right ear advantage on dichotic listening for digits although lesser right ear advantage was related to reading retardation. In the divided visual field task, the normal controls showed a left visual field advantage for digits which it is argued resulted from a failure in fixation linked to reading habits. Within the dyslexic group greater reading deficiency was associated with relative bilateralization for visual verbal processing. The results therefore support the hypothesis.     

Microcomputer-aided assessment using standard psychometric procedures

This paper describes the opportunities offered by the application of commercially available, inexpensive microcomputers to computer-assisted administration of standard psychometric procedures. The rationale underlying this application and the requirements of software design are discussed. A project based upon the APPLE microcomputer is described, together with an example of the software being developed. Preliminary work and planned development and evaluation are reported.     

Self-Concept Clarity and Preferred Coping Styles

ABSTRACT This study examined the relation between self-concept clarity and (a) preferred general coping styles, (b) coping with a specific event, and (c) coping with a specific ongoing situation in 175 undergraduate students. The results of the regression analyses for general coping styles indicated that self-concept clarity made a reliable but weak positive contribution to active coping styles (e.g., planning and taking action) and a strong negative contribution to passive coping styles (e.g., denial). The unique negative contribution of self-concept clarity to passive coping was replicated with respect to coping with a specific event and to coping with a specific ongoing situation. However, the weaker positive contribution of self-concept clarity to active coping was not replicated with respect to coping with specific events or specific ongoing situations.     

Developing conceptions of racism among young white adults in the context of cultural diversity coursework

Despite substantial research on racial attitudes and racial identity development among young white adults, little is known about the development of their conceptions about racism. The present study assessed a five-step, empirically based contextualist model of the development of conceptions about racism in young white adults, adapted from the research of Perry (1970), Kitchener and Fischer (1990), and others. A total of 55 young white adults participating in cultural diversity coursework responded to questionnaires about the nature and causes of racism and responses were classified according to the five-step model. Results indicated that many first-year white college students think about racism in dualistic terms, comparable to those described by Perry (1970) in some first-year students' epistemological concepts. Over a semester, many students showed transitions to higher steps, conceptually integrating more dimensions of the problem. Such developmental transitions may be highly context-specific. Implications for educational interventions are discussed.     

Negative priming depends on prime-probe similarity: Evidence for episodic retrieval

It is well established that requiring a person to respond to a recently ignored object in a visual selection task leads to slower responding (i.e., negative priming). In the present experiment, subjects identified target letters flanked by incompatible distractor letters on prime and probe displays. Prime display distractors appeared as the target letter on one third of subsequent probe displays. We manipulated stimulus strength by means of intensity contrast between letter displays and their background. Displays were presented with either high contrast (white against a black background) or low contrast (dark gray against a black background). The important finding was that negative priming was maximal when prime and probe displays shared the same intensity contrast. These results suggest that greater similarity between prime and probe displays results in improved retrieval of prime display information. The results provide strong support for an episodic retrieval account of negative priming.     

Faith and Psychology: Integration or Separation?

This article describes the integration of spiritual and psychological issues as it pertains to a woman's coping with her husband's death. This case highlights the need to incorporate theological elements in any caregiving relationship, whether it be professional or otherwise. Finally, it challenges educational institutions to collaborate in working on the interface of faith and psychology.
