An open-learning approach to career management and guidance

Assumptions about the nature of career development are changing in the face of organisational and technical change in the workplace. Individuals are now less likely to experience secure, lifelong employment, and instead will need to face the process of career review and change with greater frequency. They will therefore need to be skilled in managing their careers effectively. Open-learning approaches to career management and guidance have until recently been comparatively little used and yet they offer the potential for action-oriented career planning, provide a career decision framework for learners, and encourage increased ownership of the career management process by the individual taking part. They can be used in educational and commercial settings to facilitate both the processes of initial career choice and those of career development and progression. From the perspective of the careers practitioner, they offer a high-volume, but not necessarily low-cost, approach to the delivery of career programmes. Evaluation evidence is reviewed from two programmes developed at the Open University and the University of Sussex respectively. The range of learning outcomes they deliver is discussed     

Troubles on moral twin earth: Moral queerness revived

J. L. Mackie argued that if there were objective moral properties or facts, then the supervenience relation linking the nonmoral to the moral would be metaphysically queer. Moral realists reply that objective supervenience relations are ubiquitous according to contemporary versions of metaphysical naturalism and, hence, that there is nothing especially queer about moral supervenience. In this paper we revive Mackie's challenge to moral realism. We argue: (i) that objective supervenience relations of any kind, moral or otherwise, should be explainable rather than sui generis; (ii) that this explanatory burden can be successfully met vis-à-vis the supervenience of the mental upon the physical, and in other related cases; and (iii) that the burden cannot be met for (putative) objective moral supervenience relations.This paper is thoroughly collaborative. The order of authorship is alphabetical. During its evolution from early drafts to its present form, we have written several related papers; see Horgan and Timmons (1991 and forthcoming), and Timmons (1990).     

The effects of strong belief structures on information-processing evaluations and choice

This study examined the influence of the strength of belief structures on selected aspects of the decision-making process. To examine these issues, a business-acquisition decision scenario was studied in an experiment. Subjects played the role of a CEO of an electronics firm and were asked to evaluate the attractiveness of six potential acquisition candidates and to rate various aspects of the associated decision process. We presented half the subjects with information that the belief structure of their organization was extreme, agreed upon, and clear. The other half was presented with information that there was disagreement about the belief structure and that it was more ambiguous and less extreme. The results clearly showed that the decision process is different for people who were presented with an agreed-upon, extreme, and tightly constructed belief structure when compared to those who received information reflecting a weak and loosely constructed belief structure. A strong belief structure resulted in less positive evaluations, information requested, and money allocated to explore incompatible acquisition candidates (and vice versa for a highly compatible candidate) when compared to subjects using a weak belief structure. In addition, subjects in the strong-belief condition reported that their decision process would be characterized by less doubt, less time, less difficulty, and less conflict compared to subjects in the weak-belief structure condition. Implications for both decision theory and practical decision processes are discussed.     

Cognitive-behavioral treatment with and without response prevention for Bulimia

We compared cognitive-behavior therapy (CBT) with and without exposure and response prevention (ERP) in the treatment of eating disorder patients who both binged and purged, and reported abnormal attitudes concerning body weight and shape. Both treatments produced significant and comparable reductions in binge-eating and purging, eating patterns, and attitudes about weight and shape at posttreatment. Treatment effects were generalized to improvements in different measures of general psychopathology, and were maintained over follow-ups of 3 and 12 months. The findings are consistent with prior research showing that CBT is an effective treatment for patients with the core features of bulimia nervosa. Furthermore, the data suggest that the addition of in-session exposure and response prevention does not enhance the effectiveness of the basic CBT program.     

Conditional probability judgments: Effects of imagining vs experiencing the conditioning event

Applications of Bayesian conditionalization often involve two temporal aspects: a probability judgment is based on knowledge at a point in time and is revised over time in light of added information. Let t, t′, and t″ designate three chronological points in time. E designates a target event which occurs or not at t″, and C designates a conditioning event which occurs or not at t′. Suppose that an individual judges P(EC) at t. If C occurs, Bayesian conditionalization requires that a judgment of P(E) at t′ is equal to the earlier judgment of P(EC). However, inconsistencies may result because a judgment of P(EC) at t is based on imagining C, while a judgment of P(E) at t′ is based on experiencing C. This study examines two sources of such inconsistencies. First, C normally is an abstraction of what might happen between t and t′. What actually happens may differ, such that an individual observes extraconditional information which affects a judgment of P(E) at t′. Second, experiencing C may change an individual's affective state, leading to greater optimism or pessimism about the occurrence of E. We report an experiment which documents both effects.     

Adaptive processing of visual motion

Three studies relating perception of motion to stimulus uncertainty are reported. Generally, detectability declines when the observer is uncertain about the direction in which a target will move, but the visibility loss associated with direction uncertainty can be attenuated if the observer has adequate practice. This attenuation seems to depend upon the observer's ability to switch among directionally selective visual mechanisms in an adaptive fashion. The implications of these findings for models of motion detection are discussed.     

Useful Field of View and Other Neurocognitive Indicators of Crash Risk in Older Adults

Older adults represent a rapidly growing segment of the driving population. Although most older drivers are safe, research has shown that this group has more crashes per mile driven than most other age groups. The purpose of the present investigation was to examine the utility of a set of commonly used neuropsychological/cognitive tests in comparison to a newer measure of visual attention (Useful Field of View; UFOV®) in predicting state-recorded, at-fault crashes over the previous five years in a group of older adult drivers. Participants (N = 239) completed tests of mental status, visual attention, memory, and UFOV®. Results show that among all cognitive tests administered, UFOV® was most strongly related to crash involvement, with high levels of sensitivity (86.3%) and specificity (84.3%) at the standard cutoff score of 40% reduction. Practical implications for the assessment of crash risk are discussed.
