外观新颖性对消费者购买意愿的影响:自我建构与产品类型的调节效应 总被引:1,自引:0,他引:1
外观创新在市场竞争中的地位越来越突出,然而因此而导致的成败案例都很普遍。如何进行外观创新更受消费者欢迎,其内在机制是什么,我们却知之甚少。基于独特性需求理论、风险感知理论及自我建构理论,本文探讨了自我建构与外观新颖性对消费者购买意愿的交互作用、影响机制以及边界条件。通过3个实验,发现对于独立型自我建构的消费者而言,高外观新颖性能引发独特性需求从而提高购买意愿,而对于相依型自我建构而言,低外观新颖性则通过降低社会风险感知从而提高购买意愿;同时,本文也确定了产品类型对该机制的调节作用,具体来讲,对于实用品,所有消费者都对低外观新颖性产品具有更强的购买意愿,而对于享乐品,所有消费者都对高外观新颖性产品具有更强的购买意愿。 相似文献

People's risky decisions are susceptible to the social context in which they take place. Across three experiments using different paradigms, we investigated the influence of three social factors upon participants' decisions: the recipient of the decision-making outcome (self, other, or joint), the nature of the relationship with the other agent (friend, stranger, or teammate), and the type of information that participants received about others' preferences: none at all, general information about how previous participants had decided, or information about a specific partner's preference. We found that participants' decisions about risk did not differ according to whether the outcome at stake was their own, another agent's, or a joint outcome, nor according to the type of information available. Participants did, however, adjust their preferences for risky options in light of social information. 相似文献

Commercial motorcycle drivers are recognised to take high risks while driving, but little is known about their perception of these risks. This paper presents the results of a survey of 400 commercial motorcyclists' perception of unsafe driving behaviours and then determine the association between the perception of unsafe driving behaviour and reported driving behaviour. The study was carried out in Dar es Salaam between December 8th 2018 and March 24th 2019. Drivers aged 18 years and above were selected from 90 parking stages within the city and completed a structured interview. Modified Poisson regression was used to estimate the prevalence ratios (PRs). We found that close to 60% of drivers considered unsafe driving to be unsafe. However, reported unsafe driving behaviour was moderately common. Our results showed that reported unsafe driving behaviour (adjusted PR = 1.7; 95% CI 1.3–2.2) was associated with a low perception of the dangers of unsafe driving among motorcyclists. The higher the earnings a driver had (adjusted PR = 1.6; 95% CI 1.2–2.0), the higher the likelihood of having a low perceived risk of unsafe behaviour. These findings suggest that commercial motorcyclists' unsafe behaviour are, for the most part, not the result of a poor perception of the involved risks. 相似文献

Since the first offender rehabilitation treatments, all theoretical approaches have been focusing on reducing risk factors that may influence recidivism, without satisfactory results. Recent resilience research has instead shown the important mediating or moderating role of protective factors and provided the theoretical principles for the Good Lives Model Comprehensive. This holistic model suggests the importance of integrating the reduction of risk factors with the reinforcement of protective factors in offenders' treatment programs. This combined action is considered the main condition through which offenders are motivated to change their life and develop a sense of agency on their current life conditions. This article presents a pilot study, aimed at analyzing the feasibility of a psychosocial intervention, based on graphic workshops. The purpose of the intervention is helping prisoners strive toward adaptation in jail, and facilitating the redesign of their life beyond bars. Drawing activities allowed prisoners to enhance their own internal and external resources, and recognize risk and protective factors that could influence their successful reintegration into society. The main limit of this study is directly linked to the setting of the penitentiary institution where the study was conducted, which is characterized by a high prisoners' turn over. 相似文献

This study used a cognitive-emotional model to examine the relations between multiple dimensions of interparental conflict and health risk behaviors among young adolescents. Participants were 151 Mexican American adolescents and their parents. At initial individual interviews, parents reported on conflict with their spouses, and adolescents reported on their parents' conflict, their appraisals of the conflict, their emotional distress, and their acculturation level. At 6-month follow-ups, adolescents reported on their risk behaviors, including substance use and sexual activity. In general, adolescents' acculturation level was not related to their risk behaviors. More frequent conflict, more conflict about the adolescent, more adolescent involvement in the conflict, and poor conflict resolution were related to greater emotional distress. More conflict about the adolescent, mothers being more demanding/dominating during conflict, and more adolescent involvement in the conflict were related to greater risk behaviors. Adolescents' cognitions mediated the link between two dimensions of parental conflict, frequency and resolution, and emotional distress. Adolescents' emotional distress mediated the association between adolescent involvement in parental conflict and adolescents' risk behaviors. 相似文献

Dimensions of Early Childhood Behavior Problems: Stability and Predictors of Change from 18 to 30 Months 总被引:4,自引:0,他引:4
The prevalence, structure, stability, and predictors of change in early behavior problems were examined in a population-based sample of Norwegian children at 18 and 30 months of age (N = 750). A clear factor structure involving four dimensions emerged at both assessment times: Two factors were characterized by externalizing behaviors and were labeled Social Adjustment and Overactive-Inattentive; one factor tapped internalizing problems and was labeled Emotional Adjustment; and the fourth, related to general immaturity, was labeled Regulation. Specific patterns of child and family risk factors were associated with stability and change over the two time points for each factor. Children with stable problems had the most problematic characteristics on all significant predictors, followed by children with problems at one, but not both, time points. The data suggest that it is possible to identify risk factors for stable problems at 18 months, allowing some prediction of those children whose problems will persist over early childhood. Since specific risk factors emerged for specific types of behavior problems, the results may provide some much-needed guidance to early intervention efforts. 相似文献

In commenting on the five articles in this special issue, this paper discusses (1) the concept of child and adolescent psychopathy, and whether adolescent psychopaths are qualitatively distinct from other young people; (2) the measurement of adolescent psychopathy; (3) the relationship between psychopathy and other personality dimensions; (4) childhood risk factors for psychopathy; (5) psychopathy in the context of risk factors for delinquency; and (6) the prevention and treatment of adolescent psychopathy. It is argued that the three dimensions of an arrogant, deceitful interpersonal style, deficient affective experience, and an impulsive or irresponsible behavioral style are most important at present in the definition of psychopathy. An ambitious research agenda is recommended, investigating the concept of adolescent psychopathy, developing new measures, conducting new longitudinal studies on development and risk factors, and mounting new randomized experiments on prevention and treatment. 相似文献

Developmental trajectories of peer-nominated aggression, risk factors at baseline, and outcomes were studied. Peer nominations of aggression were obtained annually from grades 1 to 3. Three developmental trajectories were identified: an early-onset/increasers trajectory with high levels of peer-nominated aggression at elementary school entry and increasing levels throughout follow-up; a moderate-persistent trajectory of aggression in which children were characterized by moderate levels of physical aggression at baseline; and a third trajectory with stable low levels of aggression. Children following the early-onset/increasers trajectory showed physical forms of aggression at baseline. Male gender and comorbid attention deficit/hyperactivity problems, oppositional defiant problems and poor prosocial behavior plus negative life events predicted which children would follow the early-onset/increasers trajectory of aggression. The outcomes associated with the early-onset/increaser children suggest high risk for chronically high levels of aggressive behavior. 相似文献

There are approximately one million cases oftype 1 diabetes in the US, and the incidenceis increasing worldwide. Given that two-thirdsof cases present in childhood, it is criticalthat prediction and prevention research involvechildren. In this article, I examine whethercurrent research methodologies conform to theethical guidelines enumerated by the NationalCommission for the Protection of Human Subjectsof Biomedical and Behavioral Research, andadopted into the federal regulations thatprotect research subjects. I then offer twopolicy recommendations to help researchersdesign studies that conform to these ethicalrequirements. 相似文献
