Detecting smugglers: Identifying strategies and behaviours in individuals in possession of illicit objects

Behaviour detection officers' task is to spot potential criminals in public spaces, but scientific research concerning what to look for is scarce. In two experiments, 52 (Experiment 1A) and 60 (Experiment 2A) participants carried out a mission involving a ferry crossing. Half were asked to smuggle an object; the other half were non-smugglers. In Experiment 2A, two confederates appeared to approach as if looking for someone on the ferry. Smugglers, more than non-smugglers, reported afterwards to have felt nervous, self-conscious, and conspicuous and to attempt behavioural control during the ferry crossing. The secretly videotaped ferry crossings were shown to 104 (Experiment 1B) and 120 (Experiment 2B) observers, tasked to identify the smugglers. Although they reported paying attention mostly to signs of nervousness, lie detection accuracy rate was poor (48% in Experiment 1 and 39.2% in Experiment 2) because their perceptions of nervousness did not match the experiences of nervousness reported by the (non)smugglers.     

Clarifying the nature of the distinctiveness by domain interaction in conceptual structure: comment on Cree, McNorgan, and McRae (2006)

The conceptual structure account of semantic memory (CSA; L. K. Tyler & H. E. Moss, 2001) claims that feature correlation (the degree to which features co-occur) and feature distinctiveness (the number of concepts in which a feature occurs) interact with domains of knowledge (e.g., living vs. nonliving) such that the distinctive features of nonliving things are more highly correlated than the distinctive features of living things. Evidence for (B. Randall, H. E. Moss, J. M. Rodd, M. Greer, & L. K. Tyler, 2004) and against this claim (G. S. Cree, C. McNorgan, & K. McRae, 2006) has been reported. This comment outlines the CSA, discusses Cree et al.'s (2006) critiques of the Randall et al. (2004) experiments and the CSA, and reports new analyses of property norm and behavioral data, which replicate the results reported by Randall et al. (2004).     

Elite Athletes' Experience of Coping With Emotional Abuse in the Coach–Athlete Relationship

In this article, we explore the coping strategies used by elite athletes in response to emotional abuse experienced within the coach–athlete relationship. The athletes in this study adopted emotion- and avoidance-focused coping strategies to manage their feelings in the moment that emotional abuse occurred. Over time, athletes accessed support networks and engaged in sense making to rationalize their experiences. The potential of coping-level intervention to develop individual resources and to break the cycle of emotional abuse in sport is highlighted. We suggest that as primary agents of ensuring athlete's protection, sport psychologists need appropriate safeguarding training.     

HIV infection and mental health: suicidal behaviour--systematic review

Suicide has long been associated with serious illness generally and HIV specifically. New treatments have affected prognosis in HIV positively, but it is unclear how they impact on suicidal burden (thoughts, self-harm and completions). This review examines all published suicide and HIV data for a definitive account of (1) prevalence of HIV-related suicidality, (2) measurement within studies and (3) effectiveness of interventions. Standard systematic research methods were used to gather quality published papers on HIV and suicide, searching published databases according to quality inclusion criteria. From the search, 332 papers were generated and hand searched resulting in 66 studies for analysis. Of these, 75% were American/European, but there was representation from developing countries. The breakdown of papers provided 12, which measured completed suicides (death records), five reporting suicide as a cause of attrition. Deliberate self-harm was measured in 21, using 22 instruments; 16 studies measured suicidal ideation using 14 instruments, suicidal thoughts were measured in 17, using 15 instruments. Navigating the diverse range of studies clearly points to a high-suicidal burden among people with HIV. The overview shows that autopsy studies reveal 9.4% of deceased HIV+?individuals had committed suicide; 2.4% HIV+?study participants commit suicide; approximately 20% of HIV+?people studied had deliberately harmed themselves; 26.9% reported suicidal ideation, 28.5% during the past week and 6.5% reported ideation as a side effect to medication; 22.2% had a suicide plan; 19.7% were generally "suicidal" (11.7% of people with AIDS, 15.3% at other stages of HIV); 23.1% reported thoughts of ending their own life; and 14.4% expressed a desire for death. Only three studies recruited over 70% female participants (39 studies recruited over 70% men), and six focussed on injecting drug users. Only three studies looked at interventions - predominantly indirect. Our detailed data suggest that all aspects of suicide are elevated and urgently require routine monitoring and tracking as a standard component of clinical care. There is scant evidence of direct interventions to reduce any aspect of suicidality, which needs urgent redress.     

Neural temporal dynamics of contingency judgement

The present study captures the dynamics of neural processing across positively contingent, negatively contingent, and noncontingent relations. In the setting of a hypothetical chat room conversation, participants rated the contingency of emotional response between two individuals. Event-related potentials (ERPs) were time-locked to the onset of each emotional event. Although each event alone was ambiguous regarding contingency, its neural response was characteristic of the overall contingent relation and the subsequent contingency rating. Very early displays of contingency modified the ERP anterior N1 (AN1) component amplitude. In contrast, the ERP selection negativity (SN) component amplitude seemed to be more sensitive to display properties than contingency. Our results point to the recruitment of early attentional processes for contingency judgement and highlight the efficiency of statistical information processing.     

An Ecological Process Model of Systems Change

In June 2007 the American Journal of Community Psychology published a special issue focused on theories, methods and interventions for systems change which included calls from the editors and authors for theoretical advancement in this field. We propose a conceptual model of systems change that integrates familiar and fundamental community psychology principles (succession, interdependence, cycling of resources, adaptation) and accentuates a process orientation. To situate our framework we offer a definition of systems change and a brief review of the ecological perspective and principles. The Ecological Process Model of Systems Change is depicted, described and applied to a case example of policy driven systems level change in publicly funded social programs. We conclude by identifying salient implications for thinking and action which flow from the Model.     

What propositional structure could not be

Synthese - The dominant account of propositions holds that they are structured entities that have, as constituents, the semantic values of the constituents of the sentences that express them. Since...
