预期性思考、自我调节导向与非计划购买

当消费者对非计划购买产生犹豫时,营销者应如何引导他们的购买行为？本文通过准实验与控制实验的方法探究该问题。研究结果显示：（1）营销者可以通过设计预期欣喜和预期后悔信息提高其非计划购买意向;（2）但是预期性思考的有效性还受到消费者自我调节导向的影响：预期欣喜对提高趋利导向消费者的非计划购买意向较有效,预期后悔对提高避害导向消费者的非计划购买意向较有效;（3）预期欣喜和预期后悔通过影响消费者对购买合理性的判断而影响他们的非计划购买意向。     

Facial Structure Is a Reliable Cue of Aggressive Behavior

ABSTRACT— Facial width-to-height ratio is a sexually dimorphic metric that is independent of body size and may have been shaped by sexual selection. We recently showed that this metric is correlated with behavioral aggression in men. In Study 1, observers estimated the propensity for aggression of men photographed displaying neutral facial expressions and for whom a behavioral measure of aggression was obtained. The estimates were correlated strongly with the facial width-to-height ratio of the stimulus faces and with the actual aggression of the men. These results were replicated in Study 2, in which the exposure to each stimulus face was shortened to 39 ms. Participants' estimates of aggression for each stimulus face were highly correlated between Study 2 (39-ms exposure) and Study 1 (2,000-ms exposure). These findings suggest that the facial width-to-height ratio may be a cue used to predict propensity for aggression in others.     

Reducing intergroup conflict through the consideration of future consequences

Basic social psychological research has suggested several interventions to reduce intergroup conflict. Most of these interventions, however, have been indirect and impractical to implement outside laboratory settings. Although past research has demonstrated that indirect manipulations of the consideration of future consequences reduce intergroup competition, no study of interindividual–intergroup discontinuity has tested this assumption with a direct manipulation. The present study found that when participants (individuals and members of groups) interacting in an iterated prisoner's dilemma game (PDG) were asked to predict how their opponent's choice on a second trial would be affected by their own choice on an initial trial, intergroup competition was reduced while interindividual competition remained low regardless of the manipulation. On a practical level, implications of this study provide a simple and easily implemented solution to reducing intergroup conflict in non‐laboratory situations.

Evaluation of Group Genetic Counseling for Hereditary Breast and Ovarian Cancer

As demand for genetic counseling regarding hereditary cancer continues to grow, more efficient methods of providing this service must be explored. In this pilot study, group genetic counseling was offered to two different cohorts of women seeking genetic counseling for Hereditary Breast and Ovarian Cancer. Seven group sessions, designed to cover all aspects of an individual genetic counseling appointment, were conducted. Although patients were receptive to group genetic counseling, a significant proportion chose individual counseling when given the option. Advantages of group genetic counseling include shared experience and increased efficiency. Disadvantages include increased frustration at not being eligible for genetic testing, group influence on decision-making, privacy concerns, increased need for follow-up, and difficulty booking group appointments. Overall, the level of patient satisfaction with group genetic counseling was similar to that of individual counseling. The results of this pilot study suggest that further research is needed to determine whether group genetic counseling is an acceptable alternative to individual counseling.     

An Empirical Study of Future Professionals’ Intentions to Engage in Unethical Business Practices

This paper sought to test whether student demographics (gender, age, religion, type of degree and number of courses done containing ethics) influenced the likelihood of engaging in unethical business practices. The study involved the use of a questionnaire being administered to a sample of 231 undergraduate students in Barbados. It was found that gender, religiousness, type of degree and number of courses taken containing ethics significantly impacted on the intentions to engage in unethical behaviour. It was also found that the impact of age was not conclusive. The study has several limitations including low generalisability due to the use of a non-probability sampling method, and the possibility of social desirability bias. The study informs educators about the need to integrate ethics into the curriculum as an essential component of professional training for future managers and business people. This study makes an important contribution to the ethics literature on small island developing states, since the study was done in the country of Barbados.     

Sequelae of Aggression in Acutely Suicidal Adolescents

The consequences of aggression on problem course and suicide risk were examined in 270 acutely suicidal adolescents (ages 12-17 years; 184 girls). Participants were assessed during psychiatric hospitalization (T1), 6-months post-hospitalization (T2), and 15 or more months post-hospitalization (T3). Study variables included self- and parent-reported aggression; self-reported internalizing symptoms, suicidal ideation, suicide attempt, and adverse events; and clinician-rated suicidal behavior. Aggression was not directly related to suicide attempt concurrently or prospectively. However, among more aggressive youth, internalizing symptoms were more predictive of T3 suicide attempt than among less aggressive youth. T1 aggression predicted aggressive incidents and the likelihood of incarceration prior to T3. Two-level hierarchical linear modeling indicated that self-reported aggression and internalizing problems were linked in terms of severity and rates of decline over time. Overall, parent-reported aggression was negatively associated with suicidal ideation. Findings highlight (a) the continuity and consequences of aggression, (b) a possible role of aggression in worsening suicide risk factors and potentiating suicide attempt, and (c) the importance of ongoing research on subtypes of suicidal adolescents.     

Genetic studies of stuttering in a founder population

Genome-wide linkage and association analyses were conducted to identify genetic determinants of stuttering in a founder population in which 48 individuals affected with stuttering are connected in a single 232-person genealogy. A novel approach was devised to account for all necessary relationships to enable multipoint linkage analysis. Regions with nominal evidence for linkage were found on chromosomes 3 (P=0.013, 208.8 centiMorgans (cM)), 13 (P=0.012, 52.6 cM), and 15 (P=0.02, 100 cM). Regions with nominal evidence for association with stuttering that overlapped with a linkage signal are located on chromosomes 3 (P=0.0047, 195 cM), 9 (P=0.0067, 46.5 cM), and 13 (P=0.0055, 52.6 cM). We also conducted the first meta-analysis for stuttering using results from linkage studies in the Hutterites and The Illinois International Genetics of Stuttering Project and identified regions with nominal evidence for linkage on chromosomes 2 (P=0.013, 180-195 cM) and 5 (P=0.0051, 105-120 cM; P=0.015, 120-135 cM). None of the linkage signals detected in the Hutterite sample alone, or in the meta-analysis, meet genome-wide criteria for significance, although some of the stronger signals overlap linkage mapping signals previously reported for other speech and language disorders. EDUCATIONAL OBJECTIVES: After reading this article, the reader will be able to: (1) summarize information about the background of common disorders and methodology of genetic studies; (2) evaluate the role of genetics in stuttering; (3) discuss the value of using founder populations in genetic studies; (4) articulate the importance of combining several studies in a meta-analysis; (5) discuss the overlap of genetic signals identified in stuttering with other speech and language disorders.     

Positive and Negative Expectations of Hopelessness as Longitudinal Predictors of Depression,Suicidal Ideation,and Suicidal Behavior in High‐Risk Adolescents

The relationship between hopelessness and depression in predicting suicide‐related outcomes varies based on the anticipation of positive versus negative events. In this prospective study of adolescents at elevated risk for suicide, we used two Beck Hopelessness Scale subscales to assess the impact of positive and negative expectations in predicting depression, suicidal ideation, and suicidal behavior over a 2‐ to 4‐year period. In multivariate regressions controlling for depression, suicidal ideation, and negative‐expectation hopelessness, positive‐expectation hopelessness was the only significant predictor of depressive symptoms and suicidal behavior. Clinical interventions may benefit from bolstering positive expectations and building optimism.
