The effects of perceptual set on the shape and apparent depth of subjective contours

Two experiments showed the influence of perceptual set on the perception of subjective contours. In the first, the perceived shape of a subjective-contour figure (a minimal version of the Ehrenstein configuration) was varied by altering the observer’s viewing set. The second experiment showed that apparent depth emerged in subjective-contour figures when observers were set to perceive the illusory contours.     

Visual attention to own- versus other-race faces: Perspectives from learning mechanisms and task demands

Multiple factors have been proposed to contribute to the other-race effect in face recognition, including perceptual expertise and social-cognitive accounts. Here, we propose to understand the effect and its contributing factors from the perspectives of learning mechanisms that involve joint learning of visual attention strategies and internal representations for faces, which can be modulated by quality of contact with other-race individuals including emotional and motivational factors. Computational simulations of this process will enhance our understanding of interactions among factors and help resolve inconsistent results in the literature. In particular, since learning is driven by task demands, visual attention effects observed in different face-processing tasks, such as passive viewing or recognition, are likely to be task specific (although may be associated) and should be examined and compared separately. When examining visual attention strategies, the use of more data-driven and comprehensive eye movement measures, taking both spatial–temporal pattern and consistency of eye movements into account, can lead to novel discoveries in other-race face processing. The proposed framework and analysis methods may be applied to other tasks of real-life significance such as face emotion recognition, further enhancing our understanding of the relationship between learning and visual cognition.     

Sense modality switching and serial leaming

This investigation examined the effect of sense modality switching ofinformation at various positions of a serial learning task. Different numbers of flashes of light and different numbers of “blips” ofa pure tone were used as signalsin a four-position serial learning task. The design of the study involved a switch in sense modality at each one of the four possible positions in the series. Thus, it was possible to determine if the transmission of information through one sense modality makes it progressively more difficult or more time consuming to switch to another source of information transmitted through another modality. The results generally supported the contention that, as information is received through a particular modality, there is a build-up of the disruption involved in switching sense modality.     

CULTURAL ADAPTATIONS AND DIFFUSION FOR MANAGERIAL STRATEGIES AND RESPONSES IN HONG KONG

This paper addresses the issue of cultural adaptations and diffusion for managerial strategies in host societies to which work enterprises are not indigenous in terms of their capital and management or either. With illustrations drawn from a series of case-studies of work organisations in Hong Kong managed respectively by Chinese, British and Japanese capital, there was an appearance of support for the thesis of ‘cultural’ determinism and its implications for strategical adaptations in work organisations. The implication was drawn that the Oriental nexus of altruism, trust and subtlety could be rooted in the more laudible and perhaps global influence of Confucianism. Some subsequent issues are raised. First, the problem of cultural adaptation is not specific to multinationals or foreign firms visiting from outside but also applies where the management and their ethic background are not indigenous. The other issue is the extent of cultural adaptation within work organisations, as determined by the degree of affinity with a common mother culture. The paper suggests that a common denominating mother culture can serve a strategical starting point to bring about intra-organisational and organisation-society link and harmony.     

The new qualification in careers guidance in higher education: A collaborative partnership

The raison d'être for the new Certificate and Diploma in Careers Guidance in Higher Education is outlined. The different perspectives of the partners in this enterprise–the Department of Community Studies at the University of Reading and the Association of Graduate Careers Advisory Services (AGCAS)–are discussed. The initial difficulties and successes are explored and a suggested strategy is offered for other such collaborative ventures.     

Teacher stress and guidance work in Hong Kong secondary school teachers

Major sources of stress in Hong Kong teachers were investigated, with specific reference to guidance work as a potential source of stress. A survey of 415 secondary school teachers revealed that guidance-related aspects of work constituted a major dimension of stress, with guidance teachers, female teachers, younger teachers and junior teachers perceiving more stress than their counterparts in this dimension. Workload and time pressure were perceived as the most stressful aspects of work for all teachers. Results also showed an association between stress and job satisfaction, and biographical variables. Implications of the findings for teachers doing guidance work in Hong Kong and internationally are discussed.     

Further tests of a meta-model of youthful marijuana use

This paper tests a meta-model of youthful marijuana use on students in Grades 11, 12 and 13. Although the specific models for each grade varied in detail, all followed a meta-model making the following assumptions: (1) that use or nonuse of marijuana depends primarily on attitude towards use; (2) that attitude largely reflects the perceived functional and dysfunctional consequences of use; and (3) that what people perceive as functional or dysfunctional depends on relevant personality characteristics. All three models showed satisfactory goodness-of-fit in terms of nonsignificant overidentification tests (minimum P > 0.25) and small discrepancies between observed correlations and the corresponding theoretically implied correlations. A notable feature of the Grade 13 data in contrast to those for Grade 12 and previously reported findings was the seeming unimportance of the perceived value of marijuana use for gaining acceptance from peers. It was suggested that this might reflect the selective survival into Grade 13 in the sampled community of more independently-oriented students.     

Tension headache: Theoretical problems

The traditional view of tension (muscular contraction) headache is delineated in a set of seven assumptions. A review of recent psychophysiological studies gives little support for these assumptions. However the findings provide a basis for a preliminary hypothesis about tension cases, and some predictions concerning how they can be treated. A three-systems analysis of tension headache is recommended.     

Does control of the environment enhance the perception of control?

It has been proposed that control over the environment increases the perception of control, thereby enhancing motivation. Revesman and Perlmuter (1981) found that when subjects were permitted to choose response terms to be learned on a paired-associate task, decision latencies were faster if the announcement of the desired option caused the screen upon which materials were printed to go blank. On the basis of the results of the present experiment, it was concluded that control of the environment does result in faster decision latencies, but that this effect occurs despite a decrease in the perception of control.
