Responses to broken promises: Does personality matter?

This paper examined the effects of personality traits on individuals' reactions to broken promises. We studied the effects of Neuroticism and Agreeableness on emotive and cognitive responses to breach and investigated whether these effects varied across different types (economic vs. social) and severity (high vs. low) of breach. We collected data from a scenario-based experiment with 119 undergraduate participants. Neuroticism was found to influence emotive and cognitive responses, whereas Agreeableness influenced emotive responses. Agreeableness also interacted with the type and severity of breach to differentially predict individuals' responses to breach.     

Ideological Orientation and Political Transition in Hong Kong: Confidence in the Future

In the two-component model of ideological orientation, a person's ideological position is jointly influenced by attitudinal and affective components. The present study adopted this conceptual model to predict confidence in the future of Hong Kong. Questionnaire responses were collected from 395 adults (56.8% men and 43.2% women) in Hong Kong in April 1995, some 2 years before its transfer from British to Chinese control. The results show that the level of confidence in Hong Kong was related to both attitudinal and affective identification with Hong Kong and China. These findings suggest that the transfer of government may have brought to the surface a collision of the divergent political cultures of Hong Kong and mainland China, resulting in two antagonistic political orientations that predicted confidence in the future of Hong Kong.     

Environmental,Social, and Psychological Experiences of Asian American Undergraduates: Examining Issues of Academic Persistence

A total of 160 Asian Americans (55 Chinese, 13 Filipino, 27 Japanese, 32 Korean, 15 Pacific Islander, and 18 Vietnamese) completed a series of standardized instruments assessing their environmental, social, and psychological experiences as undergraduates. The purpose of this study was threefold: to provide a composite of student experiences; to investigate the interrelationships of comfort in the university environment, social support, and self‐beliefs; and to examine the influence of these constructs on the academic persistence decisions of Asian American undergraduates. Overall, social support variables were the strongest predictors of academic persistence. Research‐derived implications for university personnel and professional counselors are provided.     

Plasticity of feature-based selection in triple-conjunction search.

Two experiments examined the disruption of feature-based selection in triple-conjunction search at multiple target transfers. In Experiment 1, after 10 training sessions, a new target possessing previous distractor features was introduced. This produced disruption in RT and fixation number, but no disruption in feature-based selection. Specifically, there was a tendency to fixate objects sharing the target's contrast polarity and shape and this did not change even upon transfer to the new target. In Experiment 2, 30 training sessions were provided with three target transfers. At the first transfer, the results replicated Experiment 1. Subsequent transfers did not produce disruption on any measure. These findings are discussed in terms of strength theory, Guided Search, rule-based approaches to perceptual learning, and the area activation model.     

Ethical Considerations for Clinical Research and Off-label Use of Ketamine to Treat Mood Disorders: The Balance Between Risks and Benefits

Previous research conducted in 1999 highlighted ethical concerns behind challenge studies inducing psychosis with ketamine and made recommendations to enhance ethical standards. Recently, a plethora of clinical trials have evaluated the efficacy of ketamine to treat mood disorders, which lead to complex ethical issues. Pharmaceutical companies and researchers hope to profit by developing patentable variations on ketamine for treating depression. Media have labeled ketamine as a “miracle” antidepressant. Some clinics offer expensive off-label use of ketamine to treat mood disorders. This article examines the ecological validity of ketamine trials, measures to protect patients, informed consent procedures, financial inducements to participants and conflict of interest of researchers, therapeutic misconception, concealment, and deception. Further recommendations are purposed to improve ethical standard of clinical research involving ketamine.     

Saving for your future self: The role of imaginary experiences

Despite increased longevity, many people fail to save the funds necessary to support their retirement. In an attempt both to elucidate and remedy this failing, research exploring the “future-self continuity” hypothesis has revealed that temporal discounting is decreased and saving increased when connections between one’s current and future self are strengthened. Here, we explored the possibility that a basic component of mental imagery – spatial visual perspective – may be an important determinant of people’s decisions to spend now or save for the future. The results of two experiments supported this prediction. Rates of saving were enhanced when a distant-future event was generated from a third-person vs. first-person vantage point, an effect that was mediated by visual bodily awareness during mental imagery.     

Using spatial vibrotactile cues to direct visual attention in driving scenes

We report two experiments designed to investigate the potential use of vibrotactile warning signals to present spatial information to car drivers. Participants performed an attention-demanding rapid serial visual presentation (RSVP) monitoring task. Meanwhile, whenever they felt a vibrotactile stimulus presented on either their front or back, they had to check the front and the rearview mirror for the rapid approach of a car, and brake or accelerate accordingly. We investigated whether speeded responses to potential emergency driving situations could be facilitated by the presentation of spatially-predictive (80% valid; Experiment 1) or spatially-nonpredictive (50% valid; Experiment 2) vibrotactile cues. Participants responded significantly more rapidly following both spatially-predictive and spatially-nonpredictive vibrotactile cues from the same rather than the opposite direction as the critical driving events. These results highlight the potential utility of vibrotactile warning signals in automobile interface design for directing a driver’s visual attention to time-critical events or information.     

Do self-report measures of social anxiety reflect cultural bias or real difficulties for Asian American college students?

Construal of the self as independent or interdependent in relation to others has been found to correlate significantly with social anxiety symptom ratings, raising concerns about possible cultural bias in these measures for Asian Americans. To investigate the validity of self-reported social anxiety symptoms, we examined the role of ethnicity in the associations among social anxiety, self-construal, and adaptive social functioning in a sample of 229 Asian- and European American college students. Results revealed that ethnicity moderated the relationship between self-construal and social anxiety such that interdependent self-construal was associated with higher social anxiety only for first generation Asian Americans. However, there were no significant ethnic differences in the associations between social anxiety self-reports and several measures of social functioning.     

Evidence for hypodescent and racial hierarchy in the categorization and perception of biracial individuals

Individuals who qualify equally for membership in two racial groups provide a rare window into social categorization and perception. In 5 experiments, we tested the extent to which a rule of hypodescent, whereby biracial individuals are assigned the status of their socially subordinate parent group, would govern perceptions of Asian-White and Black-White targets. In Experiment 1, in spite of posing explicit questions concerning Asian-White and Black-White targets, hypodescent was observed in both cases and more strongly in Black-White social categorization. Experiments 2A and 2B used a speeded response task and again revealed evidence of hypodescent in both cases, as well as a stronger effect in the Black-White target condition. In Experiments 3A and 3B, social perception was studied with a face-morphing task. Participants required a face to be lower in proportion minority to be perceived as minority than in proportion White to be perceived as White. Again, the threshold for being perceived as White was higher for Black-White than for Asian-White targets. An independent categorization task in Experiment 3B further confirmed the rule of hypodescent and variation in it that reflected the current racial hierarchy in the United States. These results documenting biases in the social categorization and perception of biracials have implications for resistance to change in the American racial hierarchy.
