During the COVID-19 pandemic people had to gauge their personal health risks in order to decide which protective behaviors to adopt. We explored whether mortality risk perceptions varied by demographic background. Using data from a nationally representative U.S. survey, we analyzed bi-weekly mortality estimates of 8339 individuals from 1 April 2020 to 21 July 2021. Consistent with a White Male Effect, White men estimated the risk of death to be lower than White women, non-White men, and non-White women. Furthermore, when linking those estimates to the actual risk of dying from COVID-19, as reflected in official fatality rates recorded by the U.S. Center for Disease Control and Prevention (CDC), White men were indeed less likely to die from the coronavirus than would be expected based on their proportion of the populations. In contrast, deaths in non-White men and non-White women were higher than would be expected. Thus, subjective risk perceptions tracked objective mortality risks. Because White men tend to disproportionally hold positions with high decision-making power, although biased risk estimates may be less likely to have negative consequences for themselves, they may be especially detrimental to those for whom such decisions are made.  相似文献

Pre-recorded, or “canned” laughter is often used to encourage audience laughter. Previous research suggests that hearing others laugh can influence an audience, although several variables moderate its effects. We examined an unexplored moderator, hypothesizing that canned laughter would influence listeners only if they believed the laughter came from fellow in-group members. We manipulated the presence or absence of canned laughter in a potentially humorous recording and participants’ beliefs about the in-group or out-group composition of the laughing audience. The results confirmed our hypothesis: participants laughed and smiled more, laughed longer, and rated humorous material more favorably when they heard in-group laughter rather than out-group laughter or no laughter at all.  相似文献

The experimental manipulation of response biases in recognition-memory tests is an important means for testing recognition models and for estimating their parameters. The textbook manipulations for binary-response formats either vary the payoff scheme or the base rate of targets in the recognition test, with the latter being the more frequently applied procedure. However, some published studies reverted to implying different base rates by instruction rather than actually changing them. Aside from unnecessarily deceiving participants, this procedure may lead to cognitive conflicts that prompt response strategies unknown to the experimenter. To test our objection, implied base rates were compared to actual base rates in a recognition experiment followed by a post-experimental interview to assess participants’ response strategies. The behavioural data show that recognition-memory performance was estimated to be lower in the implied base-rate condition. The interview data demonstrate that participants used various second-order response strategies that jeopardise the interpretability of the recognition data. We thus advice researchers against substituting actual base rates with implied base rates.  相似文献

The present study evaluated two primary care parenting interventions. First, we evaluated the most widely used Dutch practices for primary care parenting support. Second, we assessed the applicability of the Primary Care Triple P approach, which is now being utilized in a wide variety of primary care settings. Both interventions target parents of children with mild to moderate behavioural and/or emotional problems, with the aim of improving parenting skills and thereby decreasing child problems. We examined the interventions in pre‐, post‐ and follow‐up assessment, and compared the results. Both interventions produced significant reductions in reported child emotional and behaviour problems, that also remained after 3 months. For both groups, parenting styles were also found to have improved at both post‐test and follow‐up measurement. When compared with the regular Dutch parenting consultation practices, however, the Primary Care Triple P approach produced greater reductions in parental laxness and total parenting dysfunction, and greater improvement in total parenting competence at both post‐test and follow‐up. Primary Care Triple P may even—in light of the greater improvements in parenting skills and total parental competences in the Triple P group than in the regular Dutch parenting consultation group—produce better results in the long run concerning child behaviour and emotional problems.

The progress in prenatal medicine raises complex questions with respect to the physician–patient relationship. The physician needs to reconcile medical aspects, ethical principles as well as judicial norms. Already, during the first trimester, the physician has to put into practice the schedule combining for each individual pregnancy physical, laboratory and other appropriate exams. Physicians are under the obligation to inform in a clear and comprehensive way without creating unnecessary anxiety for their patients. Legal requirements include informed consent, the respect for the patient's right to self-determination, and compliance with the Swiss federal law on genetic testing, especially with its articles on prenatal screening and diagnosis. This article discusses the complexity of obstetrical practice when it comes to delivering adequate information within the scope of ethical and legal requirements in Switzerland.  相似文献

In this study we investigated the effects of state and trait aspects of self-focused attention on genital and subjective sexual arousal of sexually functional, healthy women during presentation of audiovisual erotic stimuli. Psychophysiological sexual response was measured as vaginal pulse amplitude using a vaginal photoplethysmograph. Experiential aspects of sexual arousal were measured both during stimulus presentation and retrospectively after stimulus offset. Trait level of sexual self-focus was measured with the Sexual Self-Consciousness Scale. State self-focus was induced by switching on a TV camera that pointed at the participant's face and upper torso. A manipulation check revealed that both groups experienced equally elevated levels of self-focused attention of their physical appearance. Induction of state self-focus per se did not affect genital responses, but an interaction effect of self-focus and participants' level of trait sexual self-focus was revealed. Compared with women with low scores on this trait, women with high scores exhibited smaller genital responses when state self-focus was induced. Both groups did not differ when no self-focus was induced. Increase of state self-focus did not affect subjective sexual arousal, but participants with a high level of trait sexual self-focus reported stronger subjective arousal, compared with those with low trait level. The results were discussed with reference to previous work in this field. Some implications for treatment of sexual arousal disorder were discussed.  相似文献
