Research shows that parents have a strong influence on the party preferences of their children. Yet little is known about how such preferences are transmitted in multiparty systems with weak party identification and high electoral volatility. We propose a model of intergenerational transmission that includes both direct effects of parents' party preferences on those of their children, as well as indirect effects through left–right and issue positions. We test this model with original survey data of Dutch adolescents (14–20 years old) and their parents (N = 751 adolescent-parent pairs). We find two paths through which parents exert influence on the party preferences of their adolescent children. On the first path, parental party preferences function as a direct predictor of adolescent party preferences. On the second path, adolescent left–right and issue positions function as a mediator between parental left–right and issue positions and adolescent party preferences, with the effect of left–right positions being stronger than that of issue positions. The frequency with which adolescents discuss political topics with their parents moderates these effects.  相似文献

People generally intend to act more on beliefs and attitudes about which they have greater certainty. However, we introduce a boundary condition to the positive association between certainty and behavioral intentions—behavioral extremity. Uncertainty about a threatening issue like COVID-19 can be disconcerting, and we propose that uncertain people cope in part through increased openness to extreme actions like accepting risky medical treatments and aggression toward those defying mitigation policies. Testing this, we compiled and analyzed all the data on certainty about COVID-19 mitigation policies and willingness to engage in mitigation-related behaviors that our lab collected during the pandemic (6 samples, 20 behaviors, Ns up to 1496). External ratings of the behaviors' extremity moderated certainty-willingness associations: whereas greater certainty was associated with increased willingness to engage in moderate behaviors (the typical result), lower certainty was associated with increased willingness to engage in extreme behaviors, especially among those worried about becoming ill.  相似文献

On March 11, 2004, Al-Qaeda set off 10 bombs on several train routes in Madrid. 192 people were killed and 2,000 wounded. In this study, 1,179 questionnaires were administered Week 2 after the attacks to residents 18 years and over from the affected geographical areas. The questionnaire included items about sociodemographic variables and exposure to the attacks. Psychological effects were assessed as presence of acute stress and depressive symptomatology and functional impairment. 46.7% of the sample presented symptomatology of acute stress and 49.6% depressive symptoms. Among the symptoms of acute stress, the most frequent were re-experiencing (72.5%) and dissociative symptoms (71.8%). The chief predicting variables in symptomatology were being female, over 65 yr. old, and a habitual train user. The large number of affected people was refined with an item analysis and the consideration of severity of interference in psychosocial functioning.  相似文献

The attention network test (ANT) assesses efficiency across alerting, orienting, and executive components of visual attention. This study examined approaches to assessing auditory attention networks, and performance was compared to the visual ANT. Results showed (1) alerting was sufficiently elicited in a pitch discrimination and sound localization task, although these effects were unrelated, (2) weak orienting of attention was elicited through pitch discrimination, which varied based on ISI and conflict level, but robust orienting of attention was found through sound localization, and (3) executive control was sufficiently assessed in both pitch discrimination and sound localization tasks, but these effects were unrelated. Correlation analysis suggested that, unlike alerting and orienting, sound localization auditory executive control functions tap a shared attention network system. Overall, the results suggest that auditory ANT measures are largely task and modality specific, with sound localization offering potential to assess all three attention networks in a single task.  相似文献

Differences between groups in socio‐economic status (SES) are becoming more salient nowadays. In this context, we examined the animalistic and mechanistic dehumanization that both low and high‐SES groups may experience respectively by conducting three studies. In study 1, we manipulated the SES of two fictitious groups (low vs. high‐SES) and measured the humanity ascribed to them. Results showed that the low‐SES group was animalized in comparison with the high‐SES group, which was mechanized. In study 2, we manipulated the humanity of two fictitious groups by describing them as animals or machines and measured the perceived SES of the groups. Participants tended to attribute lower SES to the group described as animals and higher SES to the group described as machines. Finally, in study 3, we used an Implicit Association Test to replicate the results of studies 1 and 2. Taken together, these studies show that low‐SES groups are considered as animal‐like whereas high‐SES groups are seen as robot‐like. We discuss the implications of these findings in relation to the justification of income inequality within our society.  相似文献

Uncontrollability has been often associated with impaired or rigid cognitive processing. However, perceived stability of uncontrollable events modulated some of these detrimental effects on cognition. We investigated whether the experience of sequential control loss and restoration can enhance cognitive flexibility. We manipulated uncontrollability using a concept formation procedure that entailed either only unsolvable tasks (control deprivation condition), unsolvable tasks followed by solvable ones (control restoration condition) or only solvable tasks (control condition). To assess cognitive flexibility, we used a task-switching procedure that incorporated social categories. In Experiment 1 participants categorized people based on gender or age, and in Experiment 2 and 3 based on gender or social roles. Participants showed more flexibility in control restoration than in control deprivation condition. Additionally, in Experiments 2 and 3 this effect was mainly pronounced in the condition where the task evoked more cognitive conflict. We discuss the motivational underpinnings of unstable experiences of control loss and restoration.

Compromised neurodevelopment (ND) among infants and children is prevalent in sub-Saharan Africa. Standardized testing of ND is frequently prohibitive in these contexts, as tests require skilled staff for their application. In this paper, we present a quality assurance (QA) model (QualiND) for standardized ND testing, discussing findings and implications from our experience applying the Kaufman Assessment Battery for Children second edition (KABC-II). The QualiND model was implemented within IMPAACT P1104s study, a multisite, prospective study including 615 children affected by HIV. From 2014 to 2016, the QualiND managed 18 testers across 6 sites located in 4 African countries applying the KABC-II in 9 local languages. The QualiND is a multilevel, video-assisted iterative model incorporating remote evaluation, feedback, and supervision roles. Using an ad hoc rubric, videos of test application were evaluated by experienced staff in a centralized QA center. At each study site, testers and supervisors reviewed feedback from videos received via email from the QA center and devised an action plan to address testing errors and deficiencies. There were few instances of invalid tests and few barriers to test completion. Over 97% of KABC-II tests across sites were considered to be valid by the QA center. Overall, the QualiND model was a useful platform for remote supervision to nonspecialist and minimally trained research staff. The QualiND model may be useful to researchers and organizations involved in measuring early child development using standardized tests in low and middle-income countries.  相似文献

This paper focuses on one of Tischner’s last and little-known essays on the issues concerning work in the era of free market and the hegemony of the laws of economic calculation. In a discussion with Dominique Méda and André Gorz, Tischner diagnoses various threats to contemporary forms of work. Tischner criticizes above all the one-sided—that is, only objective—conception of today’s work. Referring to his own and original anthropologico-ethical project of work, the Polish scholar draws the reader’s attention to the need to promote the subjective model of work to be construed as interhuman dialogue. In work, thus construed, Tischner discerns a guarantee of the moral order of contemporary societies. His anthropological-ethical concept of work successfully inscribes itself in some of the models of work of the future, which are very much promoted today.

This study adopts the Valuation theory and the Self-Confrontation Method to explore the autobiographic narrative in oldest old persons, considering a temporal perspective (past, present, future). The sample comprises three men and two women (84-95 years old). The findings suggest that the narrative of oldest-old persons emerges structured in a way that their narration of the past focus on outside connections (proximity with others; success achieved); their narration of the present centers on attaining a life philosophy and proximity with others and their narration of the future concentrates on self-enhancement (maintaining autonomy vs. experiencing powerlessness and lack of involvement).  相似文献
