大学生对一般生活事件和意外事故的乐观和悲观偏差估计：直接和间接测量的比较

研究考查了大学生对一般生活事件和意外事故的乐观与悲观偏差,并检验不同测量方法是否会产生不同结果。通过对273名大学生进行问卷研究,结果发现：（1）在直接和间接测量时,被试对一般消极事件、意外事故存在乐观偏差,对幸免于意外事故存在悲观偏差;但对一般积极事件,被试在直接测量时出现乐观偏差,在间接测量时为悲观偏差。（2）在两种方法中,被试对意外事故的乐观偏差皆高于一般消极事件,但一般积极事件与幸免于意外事故的结果在直接测量时有显著差异,而在间接测量中差异不显著。（3）在直接测量时,消极事件的发生频率越低乐观偏差越严重,积极事件的发生频率越低则悲观偏差越严重;在间接测量中事件频率与偏差结果相关不显著。     

Exaggerated Self-Assessments and the Preference for Controllable Risks

People prefer controllable risks over less dangerous uncontrollable ones. Two kinds of evidence suggest that people′s belief that they are more capable than others at controlling dangerous outcomes contributes to this preference: In Study 1, the preference for controllable risks was reduced when subjects were choosing risks for another person rather than for themselves. In Study 2, this preference was stronger when the ability required to control outcomes was conducive to an "I am above average" bias than when it was not. The preference for controllable risks over less dangerous uncontrollable ones was obtained for hypothetical scenarios as well for actual choices and was shown to reduce subjects′ expected outcomes.     

Cultural variations in optimistic and pessimistic bias: do Easterners really expect the worst and Westerners really expect the best when predicting future life events?

The authors compared levels of optimistic and pessimistic bias in the prediction of positive and negative life events between European Americans and Japanese. Study 1 showed that European Americans compared with Japanese were more likely to predict positive events to occur to self than to others. The opposite pattern emerged in the prediction of negative events. Study 2 replicated these cultural differences. Furthermore, positive associations emerged between predictions and occurrence of life events 2 months later for both European Americans and Japanese. Across both studies, results of within-groups analyses indicated that both groups expected negative events to be more likely to occur to others than to self (optimistic bias). In addition, Japanese expected positive events to be more likely to occur to others than to self (pessimistic bias). However, European Americans failed to show the expected optimistic bias for positive events.     

Cultural variations on optimistic and pessimistic bias for self versus a sibling: is there evidence for self-enhancement in the west and for self-criticism in the east when the referent group is specified?

A culturally relevant framework was used to examine variations on optimistic and pessimistic bias in Westerners and Easterners. Study 1 showed that 136 European Americans compared with 159 Japanese were more likely to predict typical positive events to occur to self than to a sibling. The opposite pattern emerged in the prediction of typical negative events. Study 2 replicated these findings on the basis of predictions for atypical events in 175 European Americans and 130 Japanese. Across both studies, within-groups analyses indicated that European Americans held an optimistic bias in the prediction of positive and negative events, whereas Japanese held a pessimistic bias for negative events. These findings are taken to offer support for presumed cultural differences in self-enhancement and self-criticism between Westerners and Easterners, respectively.

Intrinsic religiousness and religious coping as life stress moderators for Catholics versus Protestants

Two prospective studies were conducted to test the stress-moderating effects of intrinsic religiousness and overall religious coping on the depression and trait anxiety of Catholic and Protestant college students. Both studies found a significant cross-sectional interaction between controllable life stress and religious coping in the prediction of Catholics' depression, with religious coping serving a protective function at a high level of controllable negative events. Both studies also found a significant prospective interaction between uncontrollable life stress and intrinsic religiousness in the prediction of Protestants' depression; the relationship between uncontrollable stress and depression was positive for low intrinsic Protestants, flat for medium intrinsic Protestants, but negative for high intrinsic Protestants. The findings are discussed in terms of their implications for the role of religion in life stress adjustment.     

Measurement of adolescents' life events: The junior high life experiences survey

The first of these two studies examined the relationship between adolescents' scores on a social desirability questionnaire and scores of negative, positive, and total life events. Only number of positive events was significantly related to social desirability. The second study compared various scoring strategies with respect to their intercorrelation and their ability to predict adolescents' maladjustment (depression, anxiety, and number of missed school days). The results demonstrated that (a) total number of events and readjustment-weighted life change scores were equally predictive of the maladjustment criteria; (b) negative events, but not positive events, however scored, were significantly related to the maladjustment criteria; (c) indices based on psychologist-judges' ratings of event desirability were not more predictive of the maladjustment criteria than were indices based on the adolescents' self-reports; and (d) uncontrollable negative events and controllable negative events were equally predictive of the maladjustment criteria.     

Counterfactual thinking about controllable events

When people think about what might have been, they mentally undo controllable rather than uncontrollable events. We report the results of two experiments in which we examined this controllability effect in counterfactual thinking. The experiments show that the mutability of controllable events is influenced by the perceived appropriateness or inappropriateness of the events. The first experiment shows that people change inappropriate controllable actions more than appropriate controllable ones. The second experiment shows that people mutate inappropriate controllable events whether the outcome is exceptional or normal with respect to intrapersonal habitual norms, and whether the outcome is positive or negative. We discuss the implications for alternative theories of counterfactual thinking.     

愤怒和悲伤情绪对助人决策的影响:人际责任归因的作用

基于具体情绪理论——评价倾向框架理论(ATF),采用两项研究考察负性情绪愤怒和悲伤对助人决策的影响,并探究人际责任归因在这一关系中的作用。两项研究均采用自传体情绪记忆任务诱发情绪,研究一中自变量情绪为组间变量,包括愤怒、悲伤和中性三个水平,因变量助人决策操作为为他人花费时间;研究二中自变量1为组间变量情绪,包括愤怒和悲伤,自变量2为组内变量人际责任归因,操作为模糊归因、不可控的情景归因、可控的自我归因三种情境,因变量助人决策操作为为他人花费金钱。结果发现:(1)与愤怒情绪相比,悲伤情绪下个体为他人花费的时间和捐助的金钱更多;(2)在模糊的人际责任归因条件下,悲伤个体会比愤怒个体捐助更多的钱。研究表明:同为负性情绪的愤怒和悲伤在助人决策上的作用不同,悲伤个体比愤怒个体做出更多的助人决策;人际责任性归因会影响附带情绪和助人决策的关系。研究结论有助于理解附带情绪对助人决策的影响,进一步丰富并延伸ATF理论的证据和领域,对发挥情境中人际责任归因在助人决策中的作用具有一定的现实意义。     

Future-event schemas and certainty about the future: automaticity in depressives' future-event predictions.

The proposition was tested that depressives make predictions about the future based on a pessimistic future-event schema. Participants varying in depression predicted whether positive and negative events would happen to them (or to an average person) in the future by pressing yes or no at a computer terminal as quickly as possible, either under a concurrent attentional load or under no such load. As hypothesized, depressives predicted more negative events and fewer positive events than did mild depressives or nondepressives and showed greater automaticity in their predictions. That is, the attentional load did not increase depressives' response latencies for either negative or positive events, even though it did so reliably for both mildly depressed and nondepressed individuals. Depressives may thus possess a highly developed future-event schema that operates efficiently in enabling future-event predictions.     

An Attributional Analysis of Social Accounts: Implications of Playing the Blame Game1

These studies proposed that effective social accounts should contain external, unstable, specific, and uncontrollable attributions. In Study I, managers provided accounts for a negative event. The accounts contained highly unstable and specific attributions but, contrary to original predictions, they also contained highly internal and controllable attributions. In Study 2, managers rated the effectiveness of the account. Account effectiveness was positively related to unstable attributions, but was negatively related to external and uncontrollable attributions. These relationships were stronger (more negative) for accounts communicated downward than upward. These results indicate that blaming others or deflecting personal responsibility for negative events may be ineffective, especially when one is in a high‐status role.     

Optimism across cultures: In response to the severe acute respiratory syndrome outbreak

Based on our early research, we predicted that the Chinese may be more optimistic and less pessimistic than North Americans in response to negative life events. A survey was conducted to investigate optimism cross culturally in the context of the severe acute respiratory syndrome (SARS) outbreaks in Canada and China. Chinese students in Beijing and European Canadians in Toronto answered questions about their perceptions of SARS. No significant cultural difference was found on dispositional optimism, as measured by the Revised Life Orientation Test (LOT-R). Unrealistic optimism was measured in the context of SARS. Both groups demonstrated unrealistic optimism (i.e. reporting that the self was less likely than an average person to get infected with SARS). Such optimistic bias was stronger among Chinese than among Canadians. Compared to the actual infection rates in Beijing and Toronto, both Chinese and Canadian participants overestimated their own chances of getting infected, indicating that they were being pessimistic. Indeed, Chinese were less pessimistic than Canadians. In addition, even though the Chinese reported more inconvenience brought by SARS than did Canadians, they also reported more positive changes brought by SARS, reflecting the Chinese dialectical views of events. Implications for research on optimism in context are discussed.     

From acclaim to blame: evidence of a person sensitivity decision bias

In a series of studies, the authors established empirical support for a general decision-making bias that they termed a person sensitvity bias. Specifically, a person sensitivity bias consists of a person positivity bias (D. O. Sears, 1983) under positive performance conditions and a person negativity bias under negative performance conditions. The authors conducted the first empirical studies of a direct comparison between individuals and objects performing the same task under both positive and negative performance conditions. Two additional studies tested the boundaries of the sensitivity bias within negatively framed decision dilemmas. The results are discussed in terms of their relevance toward a more comprehensive theory of person-object evaluation differences.     

The justice and injustice of life events

An experiment employing a sample (N=280) of undergraduates from an urban university was designed to test the general hypothesis that the perception of justice and injustice in life events depends upon the relationship between two variables that are part of the stimulus situation: the valence of the person being observed (good or bad), and the valence of the outcome experienced by that person (positive or negative). The findings from both qualitative (analysis of spontaneous comments) and quantitative scale ratings supported the prediction that justice and injustice perceptions depend respectively on whether the signs of the person–outcome valences are the same or different. Two perceptual biases were revealed by the analysis. The first was a positive outcome bias: respondents rated as more just outcomes that were positive regardless of the goodness or badness of the person in the life event. The second was a justice bias: respondents in both measures found the just life events to be more just than unjust life events to be unjust. Finally the more religious respondents perceived the life events as more just regardless of the patterns of person–outcome valences than did the less religious, suggesting a third, religiosity bias. A number of theoretical implications and questions for future research were discussed, including the quantification of the hypothesis and its cross-cultural generality.     

Depressive symptoms are associated with unrealistic negative predictions of future life events

This study examined the relationship between depressive symptoms and bias in the prediction of future life events. Responding to internet announcements, 153 participants varying widely in self-reported depression symptom severity estimated the probability of 40 events occurring over the succeeding 30 days. After the 30-day period, participants reported which events occurred. Optimistic/pessimistic biases were related to level of depressive symptoms. A non-significant optimistic bias characterized participants with low depressive symptoms whereas a significant pessimistic bias characterized participants with high depressive symptoms. Those reporting mild symptoms did not exhibit a systematic pessimistic or optimistic bias. General imprecision in predictions for undesirable events was associated with depressive symptoms. These findings suggest that depression is associated with pessimistic bias rather than accuracy in judgment.     

Does the Optimism Bias Affect Help-Seeking Intentions for Depressive Symptoms in Young People?

Help-seeking is an adaptive means to address mental health difficulties, but sufferers often fail to seek assistance. This inaction may reflect optimism bias—that is, believing one is less susceptible to negative events than others. In the present study, the authors investigate optimism bias by presenting depressive symptoms in vignette form to 263 undergraduate participants. Participants were asked to imagine oneself or a peer-group friend suffering from presented symptoms and provide ratings of problem seriousness, help-seeking importance, and prognosis. Results supported the optimism bias hypothesis in that participants reported lower levels of seriousness, lower need for help, and anticipated a more favorable prognosis for themselves compared to others on equivalent sets of symptoms. A contextual effect may exist and influence the evaluation of medium-severity symptoms when symptoms were presented from most to least severe. As symptom severity increased, females were less optimistic than males about prognosis and placed greater importance on help-seeking. The implications of these findings are discussed.     

The effect of controllability and causality on counterfactual thinking

Previous research on counterfactual thoughts about prevention suggests that people tend to focus on enabling rather than causing events and controllable rather than uncontrollable events. Two experiments explore whether counterfactual thinking about enablers is distinct from counterfactual thinking about controllable events. We presented participants with scenarios in which a cause and an enabler contributed to a negative outcome. We systematically manipulated the controllability of the cause and the enabler and asked participants to generate counterfactuals. The results indicate that when only the cause or the enabler is controllable participants undid the controllable event more often. However, when the cause and enabler are matched in controllability participants undid the enabler slightly more often. The findings are discussed in the context of the mental model, functional and judgement dissociation theories as well as previous research on counterfactual thinking. The importance of controllability and possible reasons for the special role of enablers are considered.     

An attributional analysis of excuse giving: studies of a naive theory of emotion

We conducted four studies that pertained to excuses given for a broken social contract. In an initial field investigation, participants recalled occasions in which they had given true and false reasons for not fulfilling a social obligation. Communicated reasons tended to be external to the person, uncontrollable, and unintentional (e.g., "My car broke down"), whereas withheld reasons tended to be internal, controllable, and either intentional (e.g., "I did not want to go") or unintentional (e.g., "I forgot"). The external uncontrollable excuses were anticipated to lessen the anger of the wronged party. In a subsequent simulation study, excuses based on the categories detected in Experiment 1 were manipulated and related to anger ratings. The same pattern of results was displayed, with intent and negligence provoking the highest anger ratings. The final two studies involved laboratory manipulation of a communicated reason for coming late to an experiment. In Experiment 3, a confederate conveyed either an internal controllable, an external uncontrollable, or no reason for making a subject wait, whereas in Experiment 4, subjects were detained and created their own good, bad, any, or no excuse for being tardy, which was communicated to a second, waiting subject. A consistent pattern of good excuse/external uncontrollable reason and bad excuse/internal controllable reason was displayed; offering no excuse resulted in the same judgments as giving a poor excuse. Relative to the external uncontrollable reasons, internal controllable excuses for being late augmented aversive emotional reactions, increased negative personality ratings, and resulted in a desire for no further social contact.(ABSTRACT TRUNCATED AT 250 WORDS)     

Biases in social comparisons: Optimism or pessimism?

Social comparisons typically lead to two kinds of biases: A comparative optimism bias (i.e., a tendency for people to view themselves as more likely than others to be the beneficiaries of positive outcomes) or a comparative pessimism bias (i.e., a tendency for people to view themselves as less likely than others to be such beneficiaries); rarely are people fully calibrated in terms of how they compare to others. However, there is little systematic research on the factors that determine when a comparative optimism versus pessimism bias will occur, how they can be attenuated and whether such attenuation is always desirable. In this paper, we report four studies which demonstrate the following key results: First, we show that perceived level of control over the outcome drives whether a comparative optimism or pessimism bias will occur (Study 1). Second, an increase in perceived similarity between self and a comparison target person attenuates the comparative optimism bias in domains that people view as highly controllable (Study 2a) and attenuates the comparative pessimism bias in domains that people view as less controllable (Study 2b). Finally, we show that people are willing to work harder when they experience more comparative optimism in higher control scenarios and when they experience less comparative pessimism in lower control scenarios, illustrating that motivating people to strive harder for positive outcomes can result from exacerbated or attenuated bias, depending on the context (Study 3).     

Application of a self-evaluation maintenance model to psychological health in interpersonal contexts

This study examines the possibility of applying Tesser's (1988) Self-Evaluation Maintenance Model, which focuses on self-esteem, to individual psychological health in interpersonal contexts. The participants consist of 243 college students divided into same-sex friendship pairs. The main findings show that when comparing oneself with an close friend in a domain one finds important, positive self-perception is more closely related to psychological health than a positive perception of the friend. In domains not important to the self, no relationship between psychological health and self-perception was found, regardless of the degree of intimacy. These results indicate that the degree of intimacy with the compared person and the degree of importance ascribed to the aspect being compared are connected with individual psychological health. These findings are discussed in relationship to application of the Self-Evaluation Maintenance Model to psychological health.
