Visual memory and stimulus repetition effects

Recent investigations of memory for randomly configured patterns indicate that visual memory can involve distinct short-term and long-term components. The appearance of a visual recency effect that is confined to the last-presented item is believed to result from the active visualization of this item during the retention interval. Studies of the retention of familiar visual information have also suggested that the short-term effects observed are a result of active visualization. In a review of these studies, however, we argue that the effects obtained with familiar visual information are not necessarily a result of active visualization and, indeed, may not involve anything other than long-term visual memory. For example, Rabbitt and Vyas (1979) observed a visual recency effect in a serial choice reaction time task involving familiar information. That this recency effect was confined to the final item accords with the results obtained with unfamiliar visual information. However, this choice reaction time task did not require subjects to remember previous stimuli, so it is unlikely that they actively visualized them. With the case for a distinct short-term visual memory currently resting on the recency effect interpreted as reflecting a process of active visualization, this result is especially important. In the second part of the present paper, we report a series of experiments that provides an understanding of the visual recency effect in the serial choice reaction time task. We conclude from these studies that this effect is not due to visualization or to a visual trace either decaying or being overwritten by a succeeding stimulus.     

Construction of a tape-controlled system of presenting visual-spatial and visual-temporal stimulus patterns for use in cross-modal and intramodal matching tests

A technique of tape construction is described for use in the generation and control of all combinations of auditory-temporal, visual-temporal, and visual-spatial stimulus patterns. This technique allows the development of a set of nine tasks for testing cross-modal and intramodal matching.     

Wisconsin's Research-Through-Service Program for Superior High School Students

The Research and Guidance Laboratory for Superior Students was organized at the University of Wisconsin in 1957 to conduct longitudinal research-through-service for superior high school students. It currently involves 2,000 young people from 75 Wisconsin secondary schools. Each year faculties of cooperating schools use multiple criteria to select new ninth-grade participants. Selected students visit the Laboratory annually throughout high school for evaluation, testing, counseling, and visits to classes and professors in fields of their choice. After students come to the University, Laboratory staff members visit their schools to interview parents and meet with teachers. Laboratory activities generate many research questions concerning identification, guidance, and educational and vocational development of superior students. It is intended to continue research and follow-up of Laboratory subjects for many years after they leave high school.     

Preparing for the 21st Century: Some Goals and Challenges for Studies of Infant Sensory and Perceptual Development

While acknowledging that there has been enormous progress in our understanding of sensory and perceptual development in human infancy over the past three decades, this paper looks toward future directions in preparation for the 21st century. It is argued that investigators should move away from the categorical thinking that dominates the field and focus more on developmental process in studying the acquisition of perceptual skills. Also, more attention should be paid to the functional role of perceptual skills and less to demonstrations of discrimination. In addition, researchers should attempt to bring their work and conceptualizations more in line with that on adults and older children. Future work on sensory and perceptual development in infancy will be heavily influenced by our understanding of how the brain works, especially with refinements in brain imaging and neurophysiology and with developments in computational modeling of perceptual processes. Finally, it is likely that there will be increased application of research findings to such problems as identification of infants at risk.     

Homemaking-role quality and the psychological well-being and distress of employed women

This paper examines the quality of employed women's experience in the homemaking-role and its relationship to their psychological well-being and distress. The subjects (N=403) were drawn from a random stratified sample of women, ages 25 to 55, who were employed as social workers or licensed practical nurses. Positive homemaking-role experience was associated with increased psychological well-being and lowered psychological distress. These associations were affected by the quality of the subjects' experiences in the paid work-role. Thus the favorable association of positive homemaking-role quality with psychological well-being and distress was enhanced by positive paid work-role quality, suggesting that the relationship of homemaking-role quality to the psychological outcomes is influenced by the effects of paid work-role quality on psychological well-being and distress.Data for this paper were collected as part of a larger project funded by the National Institute on Occupational Safety and Health (1 RO1-OHO-1968). The initial analyses and writing of this paper took place at the Center for Research on Women, Wellesley College, and was supported by NIMH postdoctoral training grant no. MH-17058-053. We would like to express special thanks to the late Grace K. Baruch for her enthusiastic support and encouragement of this paper.     

Exhibitionists: sexual preferences for exposing

An assessment of the sexual preferences of exhibitionists and matched non-offenders, revealed greater arousal to scenes of exposing among the offenders but the actual degree of deviant preferences was not marked. Closer analyses of the individual response profiles, using various criteria for deviance, indicated that only a small proportion of exhibitionists displayed deviant arousal. We take these results, along with the findings from previous research, to deny the primacy of sexual motivation in exhibiting behavior. We also consider these results to indicate that there is little value in determining the sexual preferences of exhibitionists when planning treatment or estimating their risk to re-offend.

‘Developing’ the Self in the Knowledge Economy

The term ‘knowledge economy’, like the term ‘globalisation’, has become a catchword in political and educational debate over the last decade or so, especially in debates upon educational policy where the role of education in preparing young people to take their part in the Knowledge Economy is often seen as paramount over other traditional schooling activities. It is said in such debates that the production of knowledge, information and skills, will become more valuable than traditional primary and secondary production. A lot is said about the knowledge required in the Knowledge Economy, and about how institutions, businesses, activities and human beings are to be ordered or structured in accordance with views of knowledge and new Management theories. But little is said of the young people expected to take their part in the knowledge economy. Do they have a choice? Is lying on a surfboard excluded from their life options? How will they be developed, trained or educated to take their part? Will they be committed to developing their selves in accordance with the model of the IT Knowledge Entrepreneur (hereinafter TIKE) presented as a model for education by policy makers in the Knowledge Economy? This article will argue against this latter notion of the development of the self, arguing that because knowledge is prioritised over ethics, there is both an inadequate notion of the self and the educational development of the self and, because of its implicit view only of ethics, an inadequate ethical and moral view of education [246 words].
