Testing for effects of racial attitudes and visual contrast on the speed of a driver’s response to a pedestrian

Although ethnic minorities are overrepresented in pedestrian-vehicle collisions, previous driving studies did not examine racial attitudes in such collisions. Our objective was to determine whether the speed of a driver’s response to a pedestrian was affected by the driver’s racial attitudes and the contrast between the pedestrian’s skin colour and background. Participants viewed simulated driving scenes of a pedestrian on a road and pressed a button as soon as they saw an obstacle. Visual information, but not racial attitudes, affected the time it took observers to respond to pedestrian and non-pedestrian stimuli in driving scenes. Results indicated that contrast affected response time even when the stimulus was subliminal. We believe this is the first demonstration of contrast effects with subliminal stimuli in a driving context. Results have implications for traffic safety and for methodology used to study racial attitudes.     

Moral Imagination, Trading Zones, and the Role of the Ethicist in Nanotechnology

The societal and ethical impacts of emerging technological and business systems cannot entirely be foreseen; therefore, management of these innovations will require at least some ethicists to work closely with researchers. This is particularly critical in the development of new systems because the maximum degrees of freedom for changing technological direction occurs at or just after the point of breakthrough; that is also the point where the long-term implications are hardest to visualize. Recent work on shared expertise in Science & Technology Studies (STS) can help create productive collaborations among scientists, engineers, ethicists and other stakeholders as these new systems are designed and implemented. But collaboration across these disciplines will be successful only if scientists, engineers, and ethicists can communicate meaningfully with each other. The establishment of a trading zone coupled with moral imagination present one method for such collaborative communication.     

Multidisciplinary Engagement with Nanoethics Through Education—The Nanobio-RAISE Advanced Courses as a Case Study and Model

This paper presents and evaluates two advanced courses organised in Oxford as part of the European project Nanobio-RAISE and suggests using their format to encourage multidisciplinary engagement between nanoscientists and nanoethicists. Several nanoethicists have recently identified the need for ‘better’ ethics of emerging technologies, arguing that ethical reflection should become part and parcel of the research and development (R&D) process itself. Such new forms of ethical deliberation, it is argued, transcend traditional disciplinary boundaries and require the active engagement and involvement of both nanoethicists and nanoscientists with the broader issues surrounding technological developments. Whereas significant research efforts into multi- and interdisciplinary collaborations during R&D processes are now emerging, opportunities for encouraging multidisciplinary engagement through education have remained relatively underexplored. This paper argues that educational programmes could be a natural extension of ongoing collaborative research efforts ‘in the lab’ and analyses how the Nanobio-RAISE courses could be used as a model for course development. In addition to exploring how the elements that were conducive to multidisciplinary engagement in this course could be preserved in future courses, this paper suggests shifting the emphasis from public communication towards ethical deliberation. Further course work could thus build capacity among both nanoscientists and nanoethicists for doing ‘better’ nanoethics.     

The Reverse-Caricature Effect Revisited: Familiarization With Frontal Facial Caricatures Improves Veridical Face Recognition

Prior research suggests that recognition of a person's face can be facilitated by exaggerating the distinctive features of the face during training. We tested if this 'reverse-caricature effect' would be robust to procedural variations that created more difficult learning environments. Specifically, we examined whether the effect would emerge with frontal rather than three-quarter views, after very brief exposure to caricatures during the learning phase and after modest rotations of faces during the recognition phase. Results indicate that, even under these difficult training conditions, people are more accurate at recognizing unaltered faces if they are first familiarized with caricatures of the faces, rather than with the unaltered faces. These findings support the development of new training methods to improve face recognition.     

The Influence of Social Regard on the Customer–Service Firm Relationship: The Moderating Role of Length of Relationship

Purpose  

The authors examine the influence of employees’ social regard toward the customers on customer satisfaction, trust, and word of mouth. In addition, we analyzed the moderating role of length of relationship between the service provider and the customer on the effects of social regard on the customer relationship outcomes.     

Criteria‐based content analysis of true and suggested accounts of events

Worldwide, the criteria‐based content analysis (CBCA) is probably the most widely used veracity assessment technique for discriminating between accounts of true and fabricated events. In this study, two experiments examined the effectiveness of the CBCA for discriminating between accounts of true events and suggested events believed to be true. In Experiment 1, CBCA‐trained judges evaluated participants' accounts of true and suggestively planted childhood events. In Experiment 2, judges analysed accounts of recent events that were experimentally manipulated to be a (a) true experience, (b) false experience believed to be true and (c) deliberately fabricated experience. In both experiments CBCA scores were significantly higher for accounts of true events than suggested events. However, this difference was not significant for participants classified as experiencing ‘full’ memories for the suggested event. Self‐report memory measures supported the findings of the CBCA analyses. Taken together these results suggest that the CBCA discriminative power is greatly constrained.

What I Was Doing Versus What I Did: Verb Aspect Influences Memory and Future Actions

ABSTRACT— This research examined whether describing past actions as ongoing using the imperfective aspect (rather than describing them as completed using the perfective aspect) promotes memory for action-relevant knowledge and reenactment of these actions in a future context. In Experiment 1 , participants who used the imperfective aspect to describe their strategy on a prior interpersonal task were more likely to use this strategy on a later task than were participants who used the perfective aspect to describe their prior strategy. Experiment 2 demonstrated that describing behaviors on a task using the imperfective rather than the perfective aspect increased willingness to resume that task by improving memory for task contents. The last two experiments showed that the effects of the imperfective aspect on memory decayed over time and that the imperfective aspect facilitated performance of a future behavior only when the described past behavior was relevant to the future behavior. Thus, the effects of aspect are moderated by memory decay and are behavior-specific.     

Beliefs About Psychological Services (BAPS): development and psychometric properties

A scale to measure attitudes towards seeking psychological help was developed (Beliefs About Psychological Services [BAPS]) and evaluated. This scale was based on items gathered from students, colleagues, and the authors when asked about common positive and negative attitudes toward psychologists and their services. Items were also based on the Fischer and Turner (1970 Fischer, EH and Turner, JLeB. 1970. Orientations to seeking professional help: Development and research utility of an attitude scale. Journal of Consulting and Clinical Psychology, 35: 79–90. [Crossref], [PubMed], [Web of Science ®] [Google Scholar]) Attitudes Toward Seeking Professional Psychological Services (ATSPPH) measure. Three studies are reported describing the construction and evaluation of the psychometric properties of the BAPS. The BAPS is an 18-item measure consisting of three subscales: Intent, Stigma Tolerance, and Expertness. Support was found for the reliability and validity of the measure.     

Power and Type I errors for pairwise comparisons of means in the unequal variances case

A Monte Carlo simulation was conducted to compare pairwise multiple comparison procedures. The number of means varied from 4 to 8 and the sample sizes varied from 2 to 500. Procedures were evaluated on the basis of Type I errors, any‐pair power and all‐pairs power. Two modifications of the Games and Howell procedure were shown to make it conservative. No procedure was found to be uniformly most powerful. For any pair power the Games and Howell procedure was found to be generally most powerful even when applied at more stringent levels to control Type I errors. For all pairs power the Peritz procedure applied with modified Brown–Forsythe tests was found to be most powerful in most conditions.     

Direct and indirect effects of parents' education on reading achievement among third graders in Sweden

Background Cultural capital in families and especially, the educational level of parents, has during the last decades been found to be the most important dimension of socio‐economic influence on school performance. How the transmission of cultural capital over generations is concretized is however not yet fully investigated. Aims The aim is to unfold the influence of home background and more specifically, to reveal some important mediating factors between the educational levels of parents and the reading achievement levels of children. Sample Data comes from the Swedish participation in Progress in International Reading Literacy Study 2001 conducted by the The International Association for the Evaluation of Educational Achievement and comprises some 10,000 students in grade 3. Methods The effects of parents' education on reading achievement are estimated with structural equation modelling. Results The results reveal that the total effect of parents' education is substantial and that almost half of this effect is mediated through other variables, i.e. the number of books at home, early literacy activities, and emergent literacy abilities at the time for school start. The article thus identifies some of the mechanisms through which parents' education exert an influence on children's literacy development. Conclusions Cultural reproduction starts in the very early childhood, in informal settings where reading aloud is an important activity. The knowledge of written language that children have at the time for school‐start influences further reading acquisition.
