Category-specific impairments? No. A critique of Sartori et al.

In this paper we examine the claim by Sartori, Miozzo, and Job (this issue) that their patient Michelangelo exhibits a category-specific deficit in naming living things. We conclude that their data are flawed in many respects and offer no reasonable basis for the conclusions they wish to draw. In addition their further claim that the data reported by Stewart, Parkin, and Hunkin (1992) are artefactual is not supported in any substantial way by examination of the findings.     

The New Trolley Problem: Driverless Cars and Deontological Distinctions

Discussion of the ethics of driverless cars has often focused on supposed real-life versions of the famous trolley problem. In these cases, a driverless car is in a position where crashing is unavoidable and all possible crashes risk harm: for example, it can either continue on its current path and crash into five pedestrians or swerve and crash into one pedestrian. There are significant disanalogies between the human versions of the trolley problem and situations faced by driverless cars which affect the application and moral significance of key deontological distinctions, such as the distinction between doing and allowing harm. The application and moral significance of the doing/allowing distinction in the context of the behaviour of driverless cars depend on (a) our conception of the behaviour of driverless cars; (b) the forms of driverless cars that are developed and used; (c) the background expectations of programmers/manufacturers/owners of driverless cars and the conditions of being able to put those cars on the roads. These are as yet unsettled – and may even be undetermined. Nonetheless, trolley problems may still be useful in thinking about the ethics of driverless cars.     

Text-based E-contact: Harnessing cooperative Internet interactions to bridge the social and psychological divide

ABSTRACT

In order to bridge the psychological and physical divide between different groups, researchers have harnessed the positive elements of the Internet to improve intergroup contact. One new and effective Internet strategy is Electronic- or E-contact. Unlike other contact approaches, E-contact is an experimental intergroup intervention that uniquely accommodates Allport’s contact theory and recategorisation processes, to create a structured, cooperative, synchronous and goal-directed online text interaction between members from different groups. E-contact has been found to successfully improve intergroup relations between Catholics and Protestants in Northern Ireland and Muslims and Catholics in Australia; and reduce bias against lesbian women and gay men, people with schizophrenia, Indigenous Australians, and transgender individuals. This paper discusses the unique engineering and advantages of E-contact interventions in comparison to existing contact strategies, identifies the theories that guide E-contact interventions, provides meta-analytic evidence of its effects, and discusses the strengths, limitations and future directions for E-contact research.     

A Systematic Review of Mass Media Campaigns for Suicide Prevention: Understanding Their Efficacy and the Mechanisms Needed for Successful Behavioral and Literacy Change

Mass media campaigns are increasingly seen as an important part of suicide prevention; however, despite their popularity, their efficacy is not well understood. The current review aimed to address key knowledge gaps regarding how mass media campaigns can be optimized to prevent suicide, by looking at their global efficacy, and mechanisms related to successful outcomes. A systematic review of the international literature examined studies which evaluated mass media campaigns targeted at suicide prevention, where suicide behaviors (mortality, attempts) or suicide literacy (knowledge, attitudes, help‐seeking) was identified as a primary outcome. Thirteen articles describing 12 unique campaigns met eligibility criteria. For behavioral outcomes, mass media campaigns appear to be most effective when delivered as part of a multicomponent suicide prevention strategy, while “standalone campaigns” were modestly useful for increasing suicide literacy. Level of exposure, repeat exposure, and community engagement appeared to be fundamental to the success of these campaigns; however, these constructs were poorly adhered to in the development and implementation of campaigns. Overall, the mixed quality of the included studies highlights a need for increased quantity, consistency, and quality of evaluations to advance the evidence base.     

Improving intergroup relations between Catholics and Protestants in Northern Ireland via E-contact

Northern Ireland is characterised by extensive segregation between its predominantly Catholic and Protestant communities. With the aim of overcoming this segregation, the current study experimentally evaluated the effectiveness of electronic or E-contact as a novel indirect contact and prejudice-reduction strategy. Here, Catholic and Protestant participants were not required to meet physically but were involved in a collaborative and goal-orientated online interaction with a member of the other community. As predicted, E-contact improved both Catholics’ and Protestants’ outgroup attitudes via improved contact expectancies and reduced intergroup anxiety. These findings provide support for the contemporary role of online interactions in actively overcoming the physical and psychological barriers that often prevent prejudice reduction in segregated communities.
