A possible strategy for circumventing vaccine hesitancy and increasing support for vaccines is moral reframing. Moral Foundations Theory suggests messages framed using individuating foundations should be more persuasive to liberals, while messages framed using binding foundations should be more persuasive to conservatives. In an experiment, we investigated the role of political ideology and moral reframing in persuading college students to support mandating COVID-19 vaccination on university campuses. We tested harm-framed and loyalty-framed interventions to persuade liberals and conservatives, respectively. Results indicated that overall conservatives were less persuaded than liberals. Liberals were more persuaded by a harm-framed than loyalty-framed message when measuring ideology categorically (but not continuously). There were no differences in persuasion among conservatives. With further research, moral reframing could be effective in increasing support for vaccines and mandatory vaccinations.  相似文献

For a joint family story-telling task, families with a schizophrenic offspring were compared to normal families on the completeness and clarity of the final composite stories and on their interactional behavior. The composite stories from schizogenic families were more “vague and confused”, fragmented, and less complete as to the five components required to satisfy the task instructions. Schizogenic families displayed more conflict, failure, and confusion during the interactional task than control families, and, fathers and mothers of schizophrenic offspring displayed more “anxiety and tension”, “depressive mood”, “evasiveness” and “lack of interest” than fathers and mothers of normal families. Mothers of schizophrenic offspring were also described as more “hostile” than control mothers. Comparing schizogenic families from which the patient was absent during the task with schizogenic families with the patient present, and with control families, indicated that the central findings were not attributable to the immediate presence and participation of the schizophrenic member.  相似文献

Responses to recently ignored information may be slower or less accurate than responses to information not recently encountered. Such negative priming effects imply that the mechanism of selective attention operates on unattended, as well as attended, information. In the present experiment, subjects judged the second and fourth letters of five-letter strings (e.g., BABAB) as “same” or “different.” Responses were slower when a target letter was identical to the distractors presented in the immediately preceding trial. This effect did not depend on which response was required on the current or preceding trial. The results suggest that ignored information is functionally disconnected from the response system as a whole, rather than from a specific response.  相似文献

Private and public sector managers were compared regarding their job characteristics and organizational commitment. We hypothesized that job characteristics would be positively related to commitment and that sector would moderate that relationship. Moderated regression analyses revealed partial support for both hypotheses. The existence of clarity and challenge were positively related to commitment. Job characteristics demonstrated a stronger relationship with commitment among private sector managers. Explanations for these findings and directions for future research are discussed.  相似文献

This is an ecological test of adaptation in head-injured adults, reporting reliability and validity of the Executive Function Route-finding Task (EFRT; Boyd and Sautter, 1985). A Likert scale was used to rate executive aspects of route-finding such as task formulation, strategy of approach, detection and correction of errors, and dependence on cueing among 31 head-injured young adults within a large rehabilitation facility. The Task has high inter-rater reliability and acceptable concurrent validity with other neuropsychological constructs.  相似文献

In a randomized clinical trial, multisystemic family preservation was shown to significantly reduce rates of criminal activity and incarceration in a sample of 84 serious juvenile offenders and their multi-need families. In the current study, archival records were searched for re-arrest an average of 2.4 years post-referral. Survival analysis showed that youths who received multisystemic family preservation were less likely to be re-arrested than were youths who had received usual services. Such results represent the first controlled demonstration that family preservation, when delivered via a clearly specified treatment model, has lasting effects with serious juvenile offenders. Implications for family preservation and juvenile justice research are discussed.  相似文献

A criterion of adequacy is proposed for theories of relevant consequence. According to the criterion, scientists whose deductive reasoning is limited to some proposed subset of the standard consequence relation must not thereby suffer a reduction in scientific competence. A simple theory of relevant consequence is introduced and shown to satisfy the criterion with respect to a formally defined paradigm of empirical inquiry.Research support was provided by the Office of Naval Research under contract No. N00014-89-J-1725 to Osherson and Weinstein, Swiss National Science Foundation under contract No. 21-32399.91 and by a Siemens Corporation grant to Osherson.  相似文献
