This study explores the plausibility of regret minimization as behavioral paradigm underlying the choice of crash avoidance maneuvers. Alternatively to previous studies that considered utility maximization, this study applies the random regret minimization (RRM) model while assuming that drivers seek to minimize their anticipated regret from their corrective actions. The model accounts for driver attributes and behavior, critical events that made the crash imminent, vehicle and road characteristics, and environmental conditions. Analyzed data are retrieved from the General Estimates System (GES) crash database for the period between 2005 and 2009. The predictive ability of the RRM-based model is slightly superior to its RUM-based counterpart, namely the multinomial logit model (MNL) model. The marginal effects predicted by the RRM-based model are greater than those predicted by the RUM-based model, suggesting that both models should serve as a basis for evaluating crash scenarios and driver warning systems.  相似文献

The present study examined the transfer of higher-order cognitive strategy training to inhibitory control. Middle school students enrolled in a comprehension- and reasoning-focused cognitive strategy training program and passive controls participated. The training program taught students a set of steps for inferring essential gist or themes from materials. Both before and after training or a comparable duration in the case of the passive controls, participants completed a semantically cued Go/No-Go task that was designed to assess the effects of depth of semantic processing on response inhibition and components of event-related potentials (ERP) related to response inhibition. Depth of semantic processing was manipulated by varying the level of semantic categorization required for response selection and inhibition. The SMART-trained group showed inhibitory control gains and changes in fronto-central P3 ERP amplitudes on inhibition trials; whereas, the control group did not. The results provide evidence of the transfer of higher-order cognitive strategy training to inhibitory control and modulation of ERPs associated with semantically cued inhibitory control. The findings are discussed in terms of implications for cognitive strategy training, models of cognitive abilities, and education.  相似文献

The article characterizes hand paths and speed profiles for movements performed in a nonplanar, 2-dimensional workspace (a hemisphere of constant curvature). The authors assessed endpoint kinematics (i.e., paths and speeds) under the minimum-jerk model assumptions and calculated minimal amplitude paths (geodesics) and the corresponding speed profiles. The authors also calculated hand speeds using the 2/3 power law. They then compared modeled results with the empirical observations. In all, 10 participants moved their hands forward and backward from a common starting position toward 3 targets located within a hemispheric workspace of small or large curvature. Comparisons of modeled observed differences using 2-way RM-ANOVAs showed that movement direction had no clear influence on hand kinetics (p < .05). Workspace curvature affected the hand paths, which seldom followed geodesic lines. Constraining the paths to different curvatures did not affect the hand speed profiles. Minimum-jerk speed profiles closely matched the observations and were superior to those predicted by 2/3 power law (p < .001). The authors conclude that speed and path cannot be unambiguously linked under the minimum-jerk assumption when individuals move the hand in a nonplanar 2-dimensional workspace. In such a case, the hands do not follow geodesic paths, but they preserve the speed profile, regardless of the geometric features of the workspace.  相似文献

Postpartum depression (PPD) is the most common complication of childbearing, and recent studies have attempted to examine risk factors associated with it. The main study hypothesis was that a protective situational factor at a sensitive time period (full rooming‐in postpartum) would moderate the associations between insecure attachment dimensions and PPD. Three hundred twelve women, in either full or partial rooming‐in, participated in a longitudinal study at the maternity ward of a tertiary healthcare center. A Demographic questionnaire and the Experiences in Close Relationships Scale were administered at 1–4 days postpartum, and the Edinburgh Postnatal Depression scale at 2 months postpartum. PPD was significantly associated with both anxious and avoidant attachment dimensions, but not with rooming‐in conditions. In addition, women in partial rooming‐in showed a positive correlation between insecure attachment dimensions and PPD, whereas no such correlation was found for full rooming‐in women. A situational factor such as full rooming‐in, which occurs at a critical time point for the mother–infant relationship, can moderate the association between maternal avoidant or anxious attachment dimensions and the mother's PPD levels. Postpartum practices, such as rooming‐in, can be personalized and thus beneficial in moderating personal risk factors for PPD.  相似文献

The outbreak of COVID-19 is affecting the lives of millions of families around the world. The current study was carried out in Israel, following the pandemic’s initial outbreak and during the resulting enforced quarantine, confining parents and children to their homes. A sample of 141 Israeli mothers with at least one child between the ages of 3 and 12 (M?=?6.92, SD?=?2.55) participated as volunteers. About half the sample (50.7%) consisted of girls. Most mothers were cohabiting with a spouse (93%). Mothers completed online questionnaires about their perceptions about the health and economic threats of COVID-19, availability of social support, their anxiety symptoms, hostile/coercive and supportive/engaged parenting behavior, and their children’s behavior problems. Results showed expected significant associations between the mothers’ reports about having little social support, their anxiety symptoms, hostile/coercive and supportive/engaged parenting behavior, and children’s externalizing problems. Likewise, expected significant associations were found between mothers’ perceptions about the health and economic threats of COVID-19, their anxiety symptoms, hostile/coercive parenting behavior, and children’s internalizing and externalizing problems. Importantly, maternal anxiety and hostile/coercive parenting behavior mediated the associations between lack of support, negative perceptions about the health and economic threats of COVID-19, and children’s behavior problems. These findings stress the importance of mothers’ mental health and parenting behaviors for children’s socioemotional adaptation in the context of COVID-19. Implications of the findings for family interventions intended to help parents and children at this time are suggested.

Abstract

Miscarriage is a relatively prevalent occurrence in our society. The reported incidence of this event indicates that 20% of all women experience a miscarriage. Women who have miscarried report friends and family responding in ways that seem to try to reduce the impact and importance of the event. This leaves the grieving woman with a sense of little support or understanding of what she had just experienced. Furthermore, the experiences reported by women who have had a miscarriage are quite different from those reported by other individuals who have experienced other types of loss such as a spouse, partner, parent, or friend. Women who have miscarried report a lack of recognition that they have experienced a loss. Little is known about how society views miscarriage or why individuals respond in such an apparently unsupportive manner to a woman who has had a miscarriage. The present work sought to determine whether miscarriage is an unrecognized loss and to assess the meaning of miscarriage to others. Although the results indicate miscarriage is viewed as a loss, it is a loss with minimal grounded or valuative meaning for others, which suggests that the cultural norm of silence surrounding early pregnancy and miscarriage should be lifted  相似文献

In a series of studies we used attachment theory as a framework to examine human-pet relationships. We proposed that, as in interpersonal relationships, people differ in their degree of anxious or avoidant attachment to their pets, and that these individual differences influence pet-related cognitions, emotions, and behavior. We constructed a self-report scale, the Pet Attachment Questionnaire (PAQ), and examined its factorial structure, associations with attachment patterns in human relationships (Studies 1-2), relation to explicit and implicit expectations concerning a pet (3-4), and reactions to the loss of a pet (5). We found that individual differences in pet attachment do occur in the domains of attachment anxiety and avoidance, and these differences contribute uniquely to the prediction of expectations about the pet and emotional reactions to its death.  相似文献

The present study sought to illuminate self-criticism and personal standards dimensions of perfectionism and dependency as specific cognitive-personality vulnerability factors that might contribute to a better understanding of numerous psychosocial problem areas that are relevant to coronary artery disease (CAD). One hundred and twenty-three patients diagnosed with clinically significant CAD completed self-report questionnaires. Zero-order correlations and factor analysis results revealed that self-criticism was primarily related to personality vulnerability (aggression/anger/hostility, Type D negative affectivity) and psychosocial maladjustment (depressive symptoms, worry, avoidant coping, support dissatisfaction), whereas personal standards was primarily related to adaptive coping (problem-focused coping, positive reinterpretation) and dependency was primarily related to worry. Hierarchical regression results demonstrated the incremental utility of self-criticism, personal standards, and dependency in relation to (mal)adjustment over and above aggression/anger/hostility, negative affectivity, and social inhibition. Continued efforts to understand the role of perfectionism dimensions and dependency in CAD appear warranted.  相似文献
