We investigated public acceptance of conditionally automated (SAE Level 3) passenger cars using a questionnaire study among 9,118 car-drivers in eight European countries, as part of the European L3Pilot project. 71.06% of respondents considered conditionally automated cars easy to use while 28.03% of respondents planned to buy a conditionally automated car once it is available. 41.85% of respondents would like to use the time in the conditionally automated car for secondary activities. Among these 41.85%, respondents plan to talk to fellow travellers (44.76%), surf the internet, watch videos or TV shows (44%), observe the landscape (41.70%), and work (17.06%). The UTAUT2 (Unified Theory of Acceptance and Use of Technology) was applied to investigate the effects of performance and effort expectancy, social influence, facilitating conditions, and hedonic motivation on the behavioural intention to use conditionally automated cars. Structural equation analysis revealed that the UTAUT2 can be applied to conditional automation, with hedonic motivation, social influence, and performance expectancy influencing the behavioural intention to buy and use a conditionally automated car. The present study also found positive effects of facilitating conditions on effort expectancy and hedonic motivation. Social influence was a positive predictor of hedonic motivation, facilitating conditions, and performance expectancy. Age, gender and experience with advanced driver assistance systems had significant, yet small (<0.10), effects on behavioural intention. The implications of these results on the policy and best practices to enable large-scale implementation of conditionally automated cars on public roads are discussed.  相似文献

Cognitive deficits associated with early Alzheimers disease (AD) have been recently operationalised in terms of an acquisition deficit and the research supporting this view is presented. However, there is still debate concerning the nature of this deficit and how underlying cognitive processes may be detrimentally affecting the ability to acquire new information in early AD. This review argues that the pattern of cognitive deficits contributing to the acquisition impairment in early AD patients may be readily interpreted within the context of a working memory model. Isolating the component processes of working memory that underlie the acquisition deficit in early AD patients will aid in the design of clinical applications that are focussed at enhancing the ability to acquire new information in everyday life.  相似文献

This study was the first to evaluate the effectiveness of three different group interventions to reduce children's reactive aggression based on the social information processing (SIP) model. In the first stage of screening, 3,734 children of Grades 4–6 completed the Reactive–Proactive Aggression Questionnaire (RPQ) to assess their reactive and proactive aggression. Respondents with a total score of z ≥ 1 on the RPQ were shortlisted for the second stage of screening by qualitative interview. Interviews with 475 children were conducted to select those who showed reactive aggression featuring a hostile attributional bias. Finally, 126 children (97 males and 29 females) aged 8 to 14 (= 9.71, SD = 1.23) were selected and randomly assigned to one of the three groups: a child group, a parent group, and a parent–child group. A significant Time × Intervention effect was found for general and reactive aggression. The parent–child group and child group showed a significant drop in general aggression and reactive aggression from posttest to 6‐month follow‐up, after controlling for baseline scores, sex, and age. However, the parent group showed no treatment effect: reactive aggression scores were significantly higher than those in the child group at 6‐month follow‐up. This study has provided strong evidence that children with reactive aggression need direct and specific treatment to reconstruct the steps of the SIP involving the selection and interpretation of cues. The intervention could help to prevent severe violent crimes at the later stage of a reactive aggressor.  相似文献

The present review examines how stepfamily members without a shared history co‐construct a shared family identity and what family processes are relevant in this stepfamily formation. Three databases (Web of Science, PsycInfo, and ProQuest) were systematically searched, resulting in 20 included qualitative studies. The meta‐ethnography approach of Noblit and Hare allowed synthesizing these qualitative studies and constructing a comprehensive framework of stepfamilies doing family. Three interdependent family tasks were identified: (a) honoring the past, (b) marking the present, and (c) investing in the future. Stepfamily members’ experiences of these family tasks are strongly affected by the dominant societal perspectives and characterized by an underlying dialectical tension between wanting to be like a first‐time family and feeling the differences in their family structure at the same time. These findings clearly demonstrate the family work that all stepfamily members undertake and provide a broader context for interpreting stepfamilies’ co‐construction of a new family identity.  相似文献

Low‐SES couples have limited resources to manage the chronic and acute stressors with which they are disproportionately faced. Although these couples are at greater risk for negative individual and relationship outcomes, evaluations of the impact of couple relationship education (CRE) in low‐SES couples have been plagued by methodological problems, most notably challenges associated with recruitment and retention. We review the literature on challenges couples face associated with low‐SES, as well as on recruitment, retention, and CRE in low‐SES, ethnic minority populations. We illustrate some of these challenges in a case study of CRE for low‐SES couples transitioning to parenthood. In this pilot study, 21 couples were recruited from a community health clinic and randomized to either an experimental treatment condition (EXP;= 11) or a treatment‐as‐usual control condition (TAU;= 10). This study sought to mitigate documented challenges with recruitment and retention: We leveraged community partnerships, attempted to build and maintain strong relationships with study participants, provided incentives for assessments as well as intervention meetings, and attempted to reduce potential barriers to enrollment and retention. Nonetheless, we had low rates of recruitment and retention. We integrate these findings and experiences with our review of previous work in this area. We make recommendations for future CRE research and practice that have potential implications for public policy in this area.  相似文献

Anger is a significant human emotion with far‐reaching implications for individuals and relationships. We propose a transactional model of anger that highlights its relational relevance and potentially positive function, in addition to problematic malformations. By evolutionary design, physical, self‐concept, or attachment threats all similarly trigger diffuse physiological arousal, psychologically experienced as anger‐emotion. Anger is first a signaling and motivational system. Anger is then formed to affirming, productive use or malformed to destructive ends. A functional, prosocial approach to anger organizes it for protective and corrective personal and relational adaptation. In our model, threat perception interacts with a person's view of self in relation to other to produce helpful or harmful anger. Inflated or collapsed views of self in relation to other produce distinct manifestations of destructive anger that are harmful to self, other, and relationship. Conversely, a balanced view of self in relation to other promotes constructive anger and catalyzes self, other, and relationship healing. Clinical use of the model to shape healing personal and relational contact with anger is explored.  相似文献

This article draws on four decades of research and clinical practice to delineate guidelines for evidence‐informed, clinically sound work with stepfamilies for couple, family, individual adult, and child therapists. Few clinicians receive adequate training in working with the intense and often complex dynamics created by stepfamily structure and history. This is despite the fact that stepfamilies are a fundamentally different family form that occurs world‐wide. As a result many clinicians rely on their training in first‐time family models. This is not only often unhelpful, but all too often inadvertently destructive. The article integrates a large body of increasingly sophisticated research about stepfamilies with the author's four decades of clinical practice with stepfamily relationships. It describes the ways in which stepfamilies are different from first‐time families. It delineates the dynamics of five major challenges stepfamily structure creates: (1) Insider/outsider positions are intense and they are fixed. (2) Children struggle with losses, loyalty binds, and change. (3) Issues of parenting, stepparenting, and discipline often divide the couple. (4) Stepcouples must build a new family culture while navigating previously established family cultures. (5) Ex‐spouses (other parents outside the household) are part of the family. Some available data are shared on the impact of cultural and legal differences on these challenges. A three‐level model of clinical intervention is presented: Psychoeducational, Interpersonal, and Intrapsychic/Intergenerational Family‐of‐Origin. The article describes some “easy wrong turns” for well‐meaning therapists and lists some general clinical guidelines for working with stepfamily relationships.  相似文献

In this article a specific type of narrative, which often appears in analytic sessions, is discussed. It is characterized by a seemingly ordinary, everyday topic and by a peculiar disruption of the narrative flow. The threefold structure of this type of narrative is described, along with its main characteristics. One element of this type of narrative is very similar to symbolic content or complex symbolic structures, e.g. dreams, the sort of material that can be used for the purpose of interpretation. The similarities as well as the differences are elaborated in the article. Thanks to the observed general structure and ‘symbolic’ nature of some parts of the narrative, it is easy to notice some of the unconscious elements, which are not familiar to the patient's ego, and to make an interpretation. Because these elements are close to the threshold of consciousness, the patient willingly accepts an interpretation based on them. This is especially true for patients whose dominant function is thinking. A temporary, working name for this type of narrative is proposed in the article: ‘disrupted narrative ? and for its disruptive part ‘narrative symbol’.  相似文献

Children are immature in face recognition, particularly in face configural decoding. This study examines the developmental difference of face recognition in another mechanism: viewpoint transformation processing. Adults and sixth‐grade children were instructed to match a series of one‐tone black face silhouettes to their corresponding front‐view faces. This task involves sophisticated calculation in pictorial information, precise viewpoint transformation, and most probably a 3‐D face representation. The results showed that although the performances were well above chance level in the recognition of familiar faces, for children, they were at chance level in the recognition of unfamiliar faces. The results indicate that children, at least to the age of about 12 years, are still immature in the processing of face viewpoint transformation compared to adults.  相似文献
