The pleasures of uncertainty: prolonging positive moods in ways people do not anticipate 总被引:4,自引:0,他引:4
Wilson TD Centerbar DB Kermer DA Gilbert DT 《Journal of personality and social psychology》2005,88(1):5-21
The authors hypothesized that uncertainty following a positive event prolongs the pleasure it causes and that people are generally unaware of this effect of uncertainty. In 3 experimental settings, people experienced a positive event (e.g., received an unexpected gift of a dollar coin attached to an index card) under conditions of certainty or uncertainty (e.g., it was easy or difficult to make sense of the text on the card). As predicted, people's positive moods lasted longer in the uncertain conditions. The results were consistent with a pleasure paradox, whereby the cognitive processes used to make sense of positive events reduce the pleasure people obtain from them. Forecasters seemed unaware of this paradox; they overwhelmingly preferred to be in the certain conditions and tended to predict that they would be in better moods in these conditions. 相似文献

Gender differences in the reported intensity of anger and fear toward hypothetical males and females were explored in three age groups (6–12 year olds, 14–16 year olds, and adults over 30) located in two different geographic areas. The samples were primarily Caucasian and included a wide range of socioeconomic groups. Subjects reported on the intensity of feelings elicited by characters in an emotion story task in which three aspects of situational context were varied: the gender of the story characters eliciting the feeling (all situations), the stereotypic gender-typed or cross-gender behavior of the eliciting character (four situations), and the affective quality of the situations (four situations). Across all three age groups, situations that were frightening, anger-provoking, or that depicted stereotypic male-negative behavior elicited the most consistent subject gender and character gender differences in reported fear and anger. Relative to males, females of all ages reported more fear in frightening, anger-producing, and male-negative stereotypic situations. Males were reported to be more frightening and anger-producing than were females in those same situations. The data also suggested that with development, females reported less intense fear of females, while males reported less intense fear of males.This research was supported by a Gender Roles grant from the Rockefeller Foundation. We appreciate their support. We would also like to thank the public school systems of Milton, Norwood, and Watertown, Massachusetts, and Saskatoon, Saskatchewan, Canada. Finally, we would like to thank Lance Davidow, John Houlihan, and Theodore Cross for statistical consultation and/or computer programming, as well as all the parents, children, and adolescents who participated in the study. 相似文献

In humans, anterograde amnesia can result from damage to the medial temporal (MT) lobes (including hippocampus), as well as to other brain areas such as basal forebrain. Results from animal classical conditioning studies suggest that there may be qualitative differences in the memory impairment following MT vs. basal forebrain damage. Specifically, delay eyeblink conditioning is spared after MT damage in animals and humans, but impaired in animals with basal forebrain damage. Recently, we have likewise shown delay eyeblink conditioning impairment in humans with amnesia following anterior communicating artery (ACoA) aneurysm rupture, which damages the basal forebrain. Another associative learning task, a computer-based concurrent visual discrimination, also appears to be spared in MT amnesia while ACoA amnesics are slower to learn the discriminations. Conversely, animal and computational models suggest that, even though MT amnesics may learn quickly, they may learn qualitatively differently from controls, and these differences may result in impaired transfer when familiar information is presented in novel combinations. Our initial data suggests such a two-phase learning and transfer task may provide a double dissociation between MT amnesics (spared initial learning but impaired transfer) and ACoA amnesics (slow initial learning but spared transfer). Together, these emerging data suggest that there are subtle but dissociable differences in the amnesic syndrome following damage to the MT lobes vs. basal forebrain, and that these differences may be most visible in non-declarative tasks such as eyeblink classical conditioning and simple associative learning. 相似文献

For the first time, the development of paw preferences in the domestic cat, Felis silvestris catus, is explored. Twelve cats were tested at ages 12 weeks, 6 months, and 1 year on a challenge requiring them to use one of their paws to retrieve food. To control for repeated testing of the same cats at different ages, the subjects' paw preferences were compared with those of cats tested just once, at 6 months (n = 11) or 1 year (n = 14) of age. Analysis revealed a significant effect of age on the distribution of cats' paw preferences. Cats were significantly more likely to be ambilateral than paw preferent at 12 weeks and at 6 months but more likely to display a lateral bias in paw use at 1 year. There was a significant positive correlation between cats' paw preferences at 6 months and at 1 year. Lateralized behavior was strongly sex related. Females had a greater preference for using their right paw; males were significantly more inclined to adopt their left. Analysis revealed no significant difference in the direction or strength of paw preferences of cats tested longitudinally or cross-sectionally at 6 months or 1 year of age. Findings indicate that cats develop paw preferences by 1 year and hint at a relative stability in preferred paw use over time. The strong sex effect observed strengthens the case for the influence of a biological mechanism in the emergence of motor asymmetry in cats. 相似文献

Functions of genetic counseling include provision of risk information and provision of support in an effort to assist with decision making. This study examines (1) the relationship among intentions to test, self-reported provision of blood sample, and receipt of test results; (2) the impact of genetic counseling on distress specific to gene status, perceived risk of developing breast and ovarian cancer in the context having BRCA1/2 mutations (mutations predisposing to increased risk of breast-ovarian cancer), and perceived risk factors for breast cancer; and (3) the clinical profile of those receiving/not receiving results. Intentions to test for BRCA1/2 mutations, self-reported provision of blood sample immediately after counseling, and receipt of test results were statistically different but highly correlated, and intentions to test increased from pre- to postcounseling. A repeated measures ANOVA found distress specific to gene status and perceived risk factors decreased from pre- to postcounseling. Further, two clinical profiles of consultands emerged: (1) those receiving results with change in intentions to test having lower levels of distress and (2) those not receiving results and those receiving results with no change in intentions to test with higher levels of distress. Our findings are consistent with the function of genetic counseling-to provide information and support to those with familial cancer, as well as to assist in decision making. The provision of support is important as distress specific to gene status may impede flexible decision making about genetic testing. 相似文献

This paper addresses a small but important subset of the challenges to ethical behaviour that face senior university administrators in their daily work, namely, errors in moral judgment which arise from over-identification and loyalty to the institution. The domain and precipitating factors are not unique to universities but may be more intensely experienced due to two features of the traditional public and private not-for-profit university that are unique. These features include the historical nature and purpose of a university and the role of the university professor in the production and dissemination of knowledge.An earlier version of this paper was presented at the Senior University Administrators Course, held in Banff, Alberta, June 15, 2004. 相似文献

A lack of clarity in psychoanalytic education has negatively affected the educational experience of candidates now in training and makes it difficult for prospective candidates to understand the field. Three basic educational concepts--learning objectives, operationalizing, and adult learning theory--can help psychoanalysts teach and assess their students in a clearer, more objective way. Using these concepts has broad implications for both psychodynamic and psychoanalytic education in the twenty-first century. 相似文献
