The difference between generating counterexamples and using them during reasoning

The aim of this article is to provide insight into the types of long-term knowledge that are used for solving causal conditional inferences. Two taxonomies were constructed to map the types of counterexample. The available counterexamples are traditionally probed via a counterexample generation task. We observed that there are some significant differences in the types of counterexample retrieved in the reasoning task versus the generation task. The generation task can be used for predicting answers that sprout from a reasoning process that takes counterexample into account, but some participants use a different reasoning process in which the available semantic information is not used as contrasting evidence. Nonetheless, we found that the results of the generation task validly predicted the proportion of inferences accepted as well as the number of counterexamples used during reasoning.

Hurry up! The role of supervisors’ time urgency and self‐perceived status for autocratic leadership and subordinates’ well‐being

This study examines the connections among supervisors’ time urgency, their leadership behavior, and subordinate outcomes. Integrating cognitive perspectives on time urgency with contemporary thinking on the psychological experience of status, we reason that supervisors’ time‐urgent personality relates positively with their autocratic leadership behavior, and we cast supervisors’ self‐perceived status as a moderator of this linkage. Moreover, we enrich this leader‐centric perspective with a complementary, more follower‐centric view, recognizing that the consequences of supervisors’ time urgency likely extend beyond their own behavior to indirectly affect their subordinates’ well‐being at work. We tested our hypotheses using a field sample of 60 supervisors and 277 of their subordinates. Results indicate that (a) supervisors with higher time urgency are more likely to exhibit autocratic leadership behavior when they also perceive themselves as having relatively high status among subordinates, but not when perceiving lower status, and (b) supervisors’ time urgency exhibits a conditional indirect effect (via autocratic leadership) on subordinates’ work stress and time pressure experiences. Hence, this study illustrates an important boundary condition for the consequences of supervisors’ time urgency, and it demonstrates that this personality characteristic not only shapes supervisors’ leadership behavior but also affects the subordinates they are charged with leading.     

Irrelevant conjunction and the ratio measure or historical skepticism

It is widely believed that one should not become more confident that all swans are white and all lions are brave simply by observing white swans. Irrelevant conjunction or “tacking” of a theory onto another is often thought problematic for Bayesianism, especially given the ratio measure of confirmation considered here. It is recalled that the irrelevant conjunct is not confirmed at all. Using the ratio measure, the irrelevant conjunction is confirmed to the same degree as the relevant conjunct, which, it is argued, is ideal: the irrelevant conjunct is irrelevant. Because the past’s really having been as it now appears to have been is an irrelevant conjunct, present evidence confirms theories about past events only insofar as irrelevant conjunctions are confirmed. Hence the ideal of not confirming irrelevant conjunctions would imply that historical claims are not confirmed. Confirmation measures partially realizing that ideal make the confirmation of historical claims by present evidence depend strongly on the (presumably subjective) degree of belief in the irrelevant conjunct. The unusually good behavior of the ratio measure has a bearing on the problem of measure sensitivity. For non-statistical hypotheses, Bayes’ theorem yields a fractional linear transformation in the prior probability, not a linear rescaling, so even the ratio measure arguably does not aptly measure confirmation in such cases.     

The assessment of surgery-related coping: The coping with surgical stress scale (COSS)

Abstract

Surgery can be regarded as a major stressor for any patient. High preoperative emotional arousal may negatively influence adjustment during surgery as well as the postoperative recovery rate. Consequently, the strategies individuals employ for coping with this stress are of prime importance for the quality of their adaptation. This paper reports the construction and empirical assessment of a new instrument for measuring strategies employed to cope with surgical stress. Factor analysis of this instrument, the Coping with Surgical Stress Scale (COSS), yielded five factors: Rumination, Optimism and Trust, Turning to Social and Religious Resources, Threat Avoidance, and Information Seeking. Internal consistencies of the corresponding subscales were satisfactory. Results concerning external relationships of the COSS with dispositional coping, state and trait anxiety, and indicators of perioperative adjustment showed that the COSS is a useful instrument for measuring surgery-related coping.     

The Impact of Perceived Corporate Citizenship on Organizational Cynicism,OCB, and Employee Deviance

This study examines the effects of corporate citizenship at the individual employee level. Four distinct contributions beyond the existing literature are offered. First, the relationship between perceived corporate citizenship (PCC) and employee organizational citizenship behavior (OCB) is further clarified. Second, the negative job behavior of employee deviance is considered as an outcome. Third, the attitude of organizational cynicism is positioned as a mediator of the relationships between PCC and the job related behaviors of OCB and employee deviance. Fourth, we disaggregate the PCC measure and explore its relationships with organizational cynicism, OCB and employee deviance. Findings illustrate that the four separate dimensions of PCC have differential relationships with the outcome variables.
