Counterfactual processing and the correspondence between events and outcomes: Normality versus value

Kahneman and Tversky (1982) have proposed a simulation heuristic such that perceivers tend to substitute ‘normal’ antecedent events for exceptional ones in psychologically ‘undoing’ a given outcome. Recently Gavanski and Wells (1989) have demonstrated that exceptional outcomes tend to be perceived as caused by exceptional events and normal outcomes by normal events, a finding more in line with the representativeness heuristic than this ‘normalization’ principle. We argue that representativeness may be determined by the evaluative tone of events as well as by probability—namely that positive events are assumed to underlie positive outcomes and negative events, negative outcomes. Both normality and value were independently manipulated in order to test the relative effects of each of these factors. In contrast to Gavanski and Wells our data indicate that preference was given to the similarity of value between events and outcome for undoing both positive and negative and normal and exceptional outcomes. Some implications of these findings for counterfactual processing are discussed.     

Determinants of subjective contour: Bourdon illusions and “unbending” effects

Wenderoth and O’Connor (1987b) reported that, although matches to the straight edge of two triangles placed apex to apex revealed an apparent bending in the direction of the chevron formed by the hypotenuse pair (the Bourdon effect), no perceptual unbending of the bent chevron occurred. Using subjective contour figures, Walker and Shank (1988b) found large and approximately equal bending and unbending effects, consistent with two theories that they proposed. In Experiment 1, using adjustable chevron matching and subjective contours, we found that Bourdon effects, equivalent in magnitude to those reported by Walker and Shank, were 4–5 times larger than unbending effects. In Experiment 2, we used a variation of Walker and Shank’s measurement technique, in which subjects selected a matching angle from a graded series. We obtained Bourdon effects similar to those in Experiment 1, but much larger unbending effects. Nevertheless, Bourdon effects were significantly larger than unbending effects in one set of data; and in another, Bourdon test means were larger than unbending test means. In both data sets, there was a large and significant pretest bending effect, which enhanced the magnitude of unbending test minus pretest scores. These results were consistent with our theory but not the theories of Walker and Shank. The variance of unbending test matches, 3–4 times that of Bourdon test matches, reflected the task difficulty. We propose that subjective obtuse angle contraction that exceeds real obtuse angle contraction explains the fact that unbending effects are larger in subjective than in real contours.     

Compathy or Physical Empathy: Implications for the Caregiver Relationship

In this article a case is made for the importance of a previously overlooked phenomenon, physical empathy orcompathy,defined as the physical manifestation of caregiver distress that occurs in the presence of a patient in physical pain or distress. According to the similarity of a caregiver's response to the original symptoms, there can be four types of compathetic response: identical, initiated, transferred, and converted. Controlling for the compathetic response may involve narrowing one's focus and/or changing caregiver attitudes. Finally, we argue that while the compathetic response may be beneficial to the caregiving relationship, enabling the provision of appropriate and adequate humane treatment and care, the caregiver must at times shield against the compathetic response in order to provide care.     

Categorization,attitude and memory for the source of attitude statements

In a study of factors influencing recognition-memory for the sources of attitude statements, a final sample of 107 subjects, aged 15–16, first rated their agreement with 24 statements concerning drug-use, 12 of which were attributed to one, and 12 to another, fictitiously named newspaper. Later, the statements were re shown to subjects with half the names altered, and subjects had to indicate which names were correct (i.e., unaltered). Discrimination sensitivity was very significantly higher in a condition where the initial relationship between the sources and the statements was systematic, so that the 12 most pro-drug statements were attributed to one newspaper and the 12 most anti-drug statements to the other, than in two conditions where the initial relationship was random, in which discrimination was at chance level. In the first of these conditions, subjects were also more likely to claim that the attributed source was correct if they had previously agreed with the statement. overall, subjects were more accurate in discriminating correct and incorrect sources for statements to which they had previously given a more moderate, or a more negative response on the agreement scale.     

Differential Prediction of Immigrant Versus Majority Group Training Performance Using Cognitive Ability and Personality Measures

There are very few studies of the differential prediction of work and training performance for immigrant groups in the Netherlands. Scores on the General Aptitude Test Battery, an intelligence test, and the Amsterdamse Biografische Vragenlijst (ABV), a frequently used Dutch personality test, and training data for 78 immigrant and 78 Dutch trainee truck drivers were collected. Lautenschlager and Mendoza’s (1986) method of step-down hierarchical regression analysis was used to check for bias in the prediction of training results. Some predictor-criterion combinations showed differential prediction, especially with less cognitive and less objective criteria. The results with respect to the intelligence test appear to be in line with the findings of the US literature.     

An EZ-diffusion model for response time and accuracy

The EZ-diffusion model for two-choice response time tasks takes mean response time, the variance of response time, and response accuracy as inputs. The model transforms these data via three simple equations to produce unique values for the quality of information, response conservativeness, and nondecision time. This transformation of observed data in terms of unobserved variables addresses the speed—accuracy trade-off and allows an unambiguous quantification of performance differences in two-choice response time tasks. The EZ-diffusion model can be applied to data-sparse situations to facilitate individual subject analysis. We studied the performance of the EZ-diffusion model in terms of parameter recovery and robustness against misspecification by using Monte Carlo simulations. The EZ model was also applied to a real-world data set.     

The role of social support in burnout among Dutch medical residents

Burnout levels among medical residents are considered high. A lack of social support has shown to have a direct effect on emotional exhaustion, and depersonalization, two of the three burnout indicators. In this study, we examined the satisfaction of medical residents with social support (emotional, appreciative and informative) received from supervisors, fellow medical residents, nurses and patients. In addition, the correlation between social support and burnout was studied. Medical residents were significantly more dissatisfied with the emotional, appreciative and informative support received from their supervisors compared with fellow residents and nurses (respectively, 13.4+/-4.0 vs. 9.9+/-2.8 and 10.0+/-2.4; 10.0+/-2.9 vs. 7.4+/-2.0 and 7.3+/-1.8; and 7.2+/-2.3 vs. 5.4+/-1.6 and 5.3+/-1.5; p<.001). Significant independent effects were found on emotional exhaustion: from dissatisfaction with emotional support [Beta=.44, p<.001, total R2=.25] and dissatisfaction with appreciative support from supervisors [Beta=.30, p<.01, total R2=.11]. Moreover, dissatisfaction with emotional support from supervisors had an independent significant effect on depersonalization [Beta=.33, p=.001, total R2=.14]. The best predictor of burnout appeared to be dissatisfaction with emotional support received from supervisors. Our results suggest that intervention programs should not only focus on the medical residents, but also on the supervisors to improve their supportive skills.     

MMPI-2 and MCMI-III scores among dutch inpatient substance abusers: Assessing correspondence and cross-cultural equivalence

The Millon Clinical Multiaxial Inventory (MCMI-II and MCMI-III) and the Minnesota Multiphasic Personality Inventory (MMPI-2) were applied to 263 Dutch inpatient substance abusers with multiple psychiatric diagnoses, and the results compared with those of 306 North-American substance abusers studied by Ward (1995). We looked for structural similarity both across groups (per instrument) and across the two instruments (per sample), using principal components analysis and congruence analysis. The component structure found by Ward was partly replicated in the Dutch group, thus cross-validating the use of the two instruments with these patients. Moreover, as found by Ward, the MMPI-2 content and supplementary scales of the Dutch sample proved to be important determinants of the first three MMPI-2 components, adding to convergent validity. Questions remained about the influence of the (dis)continuity of MCMI-II and MCMI-III on the replicability of the MCMI components.
