Impact of responsibility for a misfortune on schadenfreude and sympathy: further evidence

The authors tested the hypothesis that the more individuals are responsible for their own misfortune, the more schadenfreude (i.e., pleasure derived from another's misfortune) and less sympathy the misfortune evokes in others. The results support the hypothesis, thereby providing further evidence for the role responsibility plays in emotional reactions to the misfortunes of others.     

Sex differences in the assignment of responsibility for an accident

Two experiments examined the proposition that females assign less responsibility than males to a perpetrator in a feminine occupation and males assign less responsibility than females to a perpetrator in a masculine occupation. The results from Experiment 1 indicated that females assigned less responsibility than males to a perpetrator in a feminine occupation, whereas males and females assigned equal responsibility to a perpetrator in a masculine occupation. These results did not generalize to measures of causality, foreseeability, intent, or justification. Therefore, they suggest that responsibility may have been assigned on the basis of reliability of the perpetrator's behavior and that a measure of reliability may be more appropriate than a measure of responsibility. The results from Experiment 2 supported the contention. Females judged the behavior of a perpetrator in a feminine occupation to be more reliable than did males, and males judged the behavior of a perpetrator in a masculine occupation to be more reliable than did females.     

The effect of intentional expectancy on mental processing: a chronopsychophysiological investigation

Expected events are processed faster than unexpected ones. Previously, we have reported evidence that passive expectancies determined by the preceding event sequence mainly affected the duration of motoric processes. Here we examined the effects of instructed, intentional expectancies in a two-choice reaction time (RT) task. As predicted, RTs were shorter for expected than unexpected events. Onset of the lateralized readiness potential as an index of selective response activation, and the latency of the P300 component of the event-related potential, reflecting the duration of perceptual processing, indicated that intentional expectancy affected the time demands for central processing but did not influence the duration of early perceptual or motoric processes. Together the present and our previous results provide evidence that different kinds of expectancy can be distinguished by their locus of action within the information processing system.     

Judgements of compensation for misfortune: The role of expectation

In three questionnaire studies, we asked subjects how much compensation should be provided, by a third party, to an accident victim. We tested the hypothesis, derived from norm theory, that compensation would be greater when the injury was less to be expected, e.g. when the injury was caused by failure - as opposed to success - of a safety routine. To rule out the possibility that such expectation effects depended on subjects' anticipations of the reactions of the parties involved in the accident. the parties were said to be ignorant of factors that could affect these reactions. Effects of expectation were still found, even when subjects themselves judged the accident to be equally serious in all conditions. Information about what would have happened in the absence of the cause (e.g. if the routine had succeeded instead of failed) affected compensation. as predicted by norm theory, but expectation effects were found even when this information about counterfactuals was held constant, so norm theory cannot account for all the results. We suggest that subjects are applying simple heuristics unreflectively Subjects may also have attempted to fulfil an implicit social contract through their awards. The results cannot be explained through the hypothesis that compensation was optimal: the accident was the same, and it had no deterrent effect, so optimal compensation should be the same in all cases.     

The effect of expectancy of a threatening event on time perception in human adults

Two experiments were conducted to investigate the effect of a threatening stimulus in human adults in a temporal bisection task. In Experiment 1, for two anchor duration conditions (400/800 vs. 800/1600 ms), the participants completed trials in which the probe duration was followed by an aversive stimulus or a nonaversive stimulus. The results showed that the duration was judged longer when the participants expected an aversive rather than a nonaversive stimulus. In Experiment 2, the effect of the temporal localization of the aversive stimulus was also tested, with the aversive stimulus being presented at the beginning or at the end of the probe duration. The results revealed a temporal overestimation in each condition compared to the trials in which no aversive stimulus was presented. Furthermore, the temporal overestimation was greater when the expectation for the forthcoming threatening stimulus was longer. This temporal overestimation is explained in terms of a speeding-up of the neural timing system in response to the increase in the arousal level produced by the expectation of a threatening stimulus.     

Stereotype threat: the effect of expectancy on performance

The goal of this study was to investigate to role of expectancy as a potential mediator of performance deficits under stereotype threat. In Experiment 1, female students were assigned to one of three experimental conditions in which they were told that women perform worse (Negative information), equally (Control) or better (Positive information) than men in logical–mathematical tests. Later, they were given a difficult math test and asked to estimate their performance prior to taking the test. Consistent with predictions, participants who considered logical–mathematical abilities important and received negative information regarding the ingroup showed lower levels of expectations and a sharp decrease in performance compared to women in the positive and control conditions. Moreover, expectancy was found to partially mediate the effect of stereotype threat on performance. In Experiment 2, we tested the generalizability of these results to non‐stigmatized groups. A group of Black Americans living in Italy were provided with favorable or unfavorable information about either their minority (Blacks) or their majority (Americans) ingroup. Consistent with predictions, participants both in the minority and in the majority condition had lower expectations and under‐performed after negative information about the ingroup. However, the level of expectancy was found to mediate the decrease in performance for participants in the Black but not in the American condition. In the discussion of these results it is suggested that, although comparable performance deficits are found for minority and majority members, the underlying processes may be different.

The feature-positive effect in allocations of responsibility for collaborative tasks

People commonly believe they have contributed more to collaborative tasks than others give them credit for. We distinguish between two types of contributions – additions (such as adding words to a co-authored paper) and deletions (such as removing extraneous words) – and show that individuals are especially prone to receive less credit from others than they believe they deserve when their contributions consist of taking something away rather than adding something. Participants who shortened some writing believed they improved it just as much as did participants who lengthened some, but were seen by others as having contributed less. Although one can hardly fail to notice one's own deletions, these contributions – like any contributions that, by their very nature, leave little trace of themselves – are easy for others to overlook.     

The unpacking effect in allocations of responsibility for group tasks

Individuals tend to overestimate their relative contributions to collaborative endeavors. Thus, the sum of group members’ estimates of the percentage they each contributed to a joint task typically exceeds the logically allowable 100%. We suggest that this tendency stems partly from individuals’ inclination to regard their fellow group members as a collective rather than as individuals, and that leading people to think about their collaborators as individuals should therefore reduce the perceived relative magnitude of their own contributions. Consistent with this thesis, four experiments demonstrate that people’s tendency to claim more than their fair share of the credit for a group task is attenuated when they “unpack” their collaborators, conceptualizing them as separate individuals, rather than as “the rest of the group.”     

The placebo effect: dissolving the expectancy versus conditioning debate

The authors review the literature on the 2 main models of the placebo effect: expectancy theory and classical conditioning. A path is suggested to dissolving the theoretical impasse that has long plagued this issue. The key is to make a clear distinction between 2 questions: What factors shape placebo effects? and What learning mediates the placebo effect? The reviewed literature suggests that classical conditioning procedures are one shaping factor but that verbal information can also shape placebo effects. The literature also suggests that conditioning procedures and other sources of information sometimes shape conscious expectancies and that these expectancies mediate some placebo effects; however, in other cases conditioning procedures appear to shape placebo effects that are not mediated by conscious cognition.     

The semantic congruity effect: Some tests of the expectancy hypothesis

Subjects comparing items in memory along some dimension are usually quicker to specify the lesser (than the greater) of two low magnitude items and the greater (than the lesser) of two high magnitude ones. One account explains this congruity effect as due to subjects instructed to specify the higher as expecting high magnitude items to follow and the reverse being true for subjects specifying the lesser. Three experiments tested this expectancy hypothesis. In experiment 1, subjects were set to the actual size range of each pair before the pair was shown but the congruity effect still occurred. In experiments 2 and 3, subjects compared critical pairs from a narrow size range plus more from either the same or much broader ranges. Times to compare the critical pairs were the same regardless of the range of the other pairs that subjects were exposed to. These results are strong evidence against the expectancy hypothesis.
