Cognitive strategies in coping with expedition stress

Expeditions provide a valuable opportunity for studying processes of coping with a stressful situation. An expedition to India organized by the British Schools Exploring Society has already been reported as being accompanied by positive changes on self-report personality scales. This paper is concerned with detailed cognitive coping measures completed throughout the 6 weeks of the expedition. It needs to be noted that the results relate to young adults and to those who provided detailed coping information; the generalizability of the result is a matter for future research. The expedition presented a mixture of physical and social stresses. Men enjoyed the physical experience more than women, but women enjoyed the social experience more than men. There was generally greater reliance on personal resources than on social support in coping with stress. This was particularly true for men in coping with physical stress and women in coping with social stress. In general, the physical stresses had been better anticipated than the social ones. Positive reformulations were much more widely used as coping strategies than avoidance/resignation strategies, especially so for physical stresses. However, use of avoidance/resignation strategies was the better predictor of outcome, with those who used them being least likely to show positive personality change as a result of the expedition. The results are related to current research on stress and coping.     

The factorial structure of sleep dissatisfaction

Research into sleep problems has been dominated by a number of theoretical perspectives from each of which useful treatment applications have been derived. However, the rich diversity of problems that are subsumed under insomnia or sleep disturbance often remain unappreciated. This paper reports the results of a factor analysis performed on the combined items of two questionnaires designed to assess sleep disturbance. Six factors are described, two of which relate to cognitive aspects of sleep disturbance; two which map onto sleep onset and sleep maintenance problems; and two which are drawn from dissatisfaction with poor sleep. Correlations of factor scores with measures of neuroticism, worry and various sleep history variables provide a strong level of construct validity. The results are discussed in terms of their treatment implications.     

Multicriteria approval: application of approval voting concepts to MCDM problems

Multicriteria decision making (MCDM) methods generally require information that is difficult and expensive to obtain. It is shown in this paper that given an ordering of criteria by importance, and whether each alternative is above the average evaluation of the alternatives for each criterion, considerable information can be extracted concerning the overall rankings of the alternatives. This is done by recognizing the similarity between criteria in MCDM, and voters in social choice theory. Multicriteria approval, proposed in this paper, is an MCDM adaptation of approval voting which can be used to classify decisions into one of several categories, depending on whether, and the manner in which, a superior alternative can be identified. An exhaustive examination of all possible decision situations of tractable size is made to measure the applicability of multicriteria approval, and the approach is demonstrated in an industrial procurement case. In addition to requiring minimal information from a decision maker, multicriteria approval satisfies several desirable criteria for MCDM techniques. © 1998 John Wiley & Sons, Ltd.     

An automated food delivery system for behavioral and neurophysiological studies of learning and memory in freely moving monkeys

We describe a custom-built feeder based on stepping motor technology controlled by a laboratory computer. The feeder dispenses a wide range of foods: any fruit, vegetable, or nut. The feeder allows the investigator to reward monkeys with different foods within a single experimental day. The monkey’s motivation to perform tasks is high and does not rely upon food regulation. The avoidance of regulation, as well as the palatability and variety of the rewards dispensed by our device, distinguishes it from commercially available products. We also describe the use of the feeder in the context of novel behavioral and neurophysiological studies in freely moving monkeys.     

Religion and Partisanship in Canada

Using a survey of three thousand Canadian adults conducted by the Angus Reid Group in the autumn of 1996, we examine the continuing role of religion in shaping partisan preferences. We find that traditional religious alignments still have some impact, but are being reshaped by both religious and political developments. We find that Evangelical Protestants are drawn toward the new Reform Party, Mainline Protestants still tend toward the Progressive Conservatives, and Catholics—both English‐and French‐speaking—remain the bulwark of the Liberal Party. The New Democratic Party, however, finds its greatest resonance among secular Canadians, and the Bloc Quebecois is strongest among nominal, rather than practicing, French‐speaking Catholics. In multivariate analysis, these religious variables stand up well against other influences in explaining partisan preferences.     

Was It My Fault? Effects of Counterfactual Mutation Focus and Self‐Presentation Strategy1

A recent perspective proposes that counterfactual thinking mutates controllable events that could have prevented a specific outcome, and so provides knowledge that can be used to prevent similar outcomes in the future. This implies that counterfactual thinking does not necessarily influence causal reasoning, although they may be associated in some circumstances. Results of 2 studies reported here show that, for serious outcomes where actions of the self are antecedents and different self‐actions might have prevented the outcome, there was an associated increase in self‐blame. Findings from these studies also suggest that whether self‐mutations are reflected in public expressions of blame will depend on whether the context favors self‐serving self‐presentation strategies, or mitigating strategies incorporating the face concerns of others.     

Text or talk? Social anxiety, loneliness, and divergent preferences for cell phone use.

This paper investigates whether social anxiety and loneliness lead to contrasting beliefs and preferences among cell phone users towards texting and talking on their cell phones. Three hypotheses are examined: (1) that social anxiety and loneliness are differentially associated with generalized preferences either for texting or for talking on the cell phone, (2) that these preferences are linked to contrasting beliefs concerning the social functionality of the short message service (SMS), and (3) that these divergent beliefs mediate the effects of social anxiety and loneliness on cell phone users' generalized preferences for texting or talking. Results from an Internet questionnaire (N=158) showed that, whilst lonely participants preferred making voice calls and rated texting as a less intimate method of contact, anxious participants preferred to text, and rated it a superior medium for expressive and intimate contact. These divergent beliefs accounted for 36% and 16% of the variance in preference for texting and voice calls, respectively, and significantly attenuated the influence of loneliness and social anxiety when they were added to the regression equations for these measures. Results are discussed in terms of the hyperpersonal possibilities of mobile communications technologies.     

Predicting short-term outcome in well-being following suicidal behaviour: the conjoint effects of social perfectionism and positive future thinking

This study investigated an integrative, psychological model of suicidality involving the relationship between perfectionism and future thinking to predict short-term outcome in well-being following a suicidal episode. Two hundred and sixty-seven adults hospitalized following a self-harm episode completed a range of clinical and psychological measures in hospital and were followed up approximately two months after discharge. Hierarchical regression analyses confirmed that, among the suicidal self-harmers who had a history of repetitive self-harm (n=65), outcome among low social perfectionists changed as a function of positive future thinking such that outcome was better for those high on positive thoughts compared with those low on positive future thoughts. There was no such positive change in outcome among the high social perfectionists. There were also no significant interactive effects evident among the non-repetitive self-harmers (n=61). These findings extend recent research to suggest that socially prescribed perfectionism and positive future thinking (but not negative future thinking) are implicated in outcome following repetitive suicidality. Implications for theory and clinical practice are discussed.     

The contribution of the thumb to reaching movements

Transport of the hand towards an object and the formation of grasp are logically separable components of reaching. It has been suggested that, although the two components must be temporally co-ordinated, their spatial parameters are under the control of independent visuo-motor channels. A case study of reaching by a proficient user of a manually-operated artificial hand is presented. A pattern of natural hand usage was observed in which the index finger rather than the thumb was responsible for reduction of grasp aperture as the hand approached an object. The same pattern of usage was also observed in the artificial hand even though the mechanics of that hand make it no easier to move the finger than the thumb. This suggests that the relative stability of the thumb in the natural hand is determined, not simply by anatomy, but by a role in guiding the transport component of reaching. At least part of the spatial aspect of grasp formation is closely related to the transport component of reaching and this is evidence against theories postulating two independent visuo-motor channels controlling the spatial parameters of grasp and transport.
