Recognising facial surfaces.

The extent to which faces depicted as surfaces devoid of pigmentation and with minimal texture cues ('head models') could be matched with photographs (when unfamiliar) and identified (when familiar) was examined in three experiments. The head models were obtained by scanning the three-dimensional surface of the face with a laser, and by displaying the surface measured in this way by using standard computer-aided design techniques. Performance in all tasks was above chance but far from ceiling. Experiment 1 showed that matching of unfamiliar head models with photographs was affected by the resolution with which the surface was displayed, suggesting that subjects based their decisions, at least in part, on three-dimensional surface structure. Matching accuracy was also affected by other factors to do with the view-points shown in the head models and test photographs, and the type of lighting used to portray the head model. In experiment 2 further evidence for the importance of the nature of the illumination used was obtained, and it was found that the addition of a hairstyle (not that of the target face) did not facilitate matching. In experiment 3 identification of the head models by colleagues of the people shown was compared with identification of photographs where the hair was concealed and eyes were closed. Head models were identified less well than these photographs, suggesting that the difficulties in their recognition are not solely due to the lack of hair. Women's heads were disproportionately difficult to recognise from the head models. The results are discussed in terms of their implications for the use of such three-dimensional head models in forensic and surgical applications.     

Health-Related Decision-Making in HIV Disease

Individuals living with HIV show moderate decision-making deficits, though no prior studies have evaluated the ability to make optimal health-related decisions across the HIV healthcare continuum. Forty-three HIV+ individuals with HIV-associated neurocognitive disorders (HAND+), 50 HIV+ individuals without HAND (HAND?), and 42 HIV? participants were administered two measures of health-related decision-making as part of a comprehensive neuropsychological battery: (1) The Decisional Conflict Scale (DCS), and (2) The Modified UCSD Brief Assessment for Capacity to Consent (UBACC-T). Multiple regression analyses revealed that HAND was an independent predictor of both the DCS and the UBACC-T, such that the HAND+ sample evidenced significantly poorer scores relative to comparison groups. Within the HIV+ sample, poorer health-related decision-making was associated with worse performance on tests of episodic memory, risky decision-making, and health literacy. Findings indicate that individuals with HAND evidence moderate deficits in effectively comprehending and evaluating various health-related choices.     

Designated as Dangerous: Characteristics of Sex Offenders Subject to Post‐Sentence Orders in Australia

The earliest characterisation of Australian sex offenders subjected to post‐sentence legislation is presented. Demographic, developmental, clinical, and criminal characteristics were obtained for sex offenders under post‐sentence orders in Western Australia, New South Wales, and Victoria. Data on 50 offenders were recorded from psychological and psychiatric risk assessment reports statutorily required at the initiation of post‐sentence legal proceedings. The findings describe a group of demonstrably dangerous men who exhibited an early onset of sexual offending, high rates of mental disorder, sexual deviance, and antisociality. Their developmental histories are characterised by early deprivation, disadvantage, abuse, early exposure to substance abuse, and social and psychological dislocation. These offenders present a conundrum to criminal justice agencies. They are an objectively unfortunate group and have engaged in significantly harmful behaviours. However, the early onset of their offending suggests that early intervention services, such as those offered by mental health professionals, have a critically important role to play in any effort to alter offending trajectories such as those exhibited in this sample. A paradigm shift in public policy from a post hoc model to a well‐resourced preventative and public health approach to the problem of sexual violence is proposed. Broad treatment implications are also considered.     

Exploring the Creation of Picasso's Guernica: Composition Studies,Chance, Metaphors,and Expertise

Simonton (2007 Simonton , D. K. ( 2007 ). The creative process in Picasso's Guernica sketches: Monotonic improvements versus nonmonotonic variants . Creativity Research Journal , 19 , 329 – 344 .[Taylor & Francis Online], [Web of Science ®] , [Google Scholar]) offered evidence for his Darwinian theory of creativity—blind nonmonotonic variation and selection—based on ratings of Picasso's preliminary sketches of the components for Guernica. This comment reexamines the sketches, adding two major sources of information: (a) consideration of the changing conceptions of the composition, as well as the components, and (b) inclusion of sketches from Picasso's first vision for his mural, the Studio sketches. Such analysis supports the notion of nonmonotonic variation including backtracking. It also suggests that the final mural, although radically different in its components from the Studio sketches, drew on the composition and theme of that initial vision for the mural, but in a completely reimagined form when a chance event pulled Picasso's thinking in a new direction. This comment also describes how Picasso drew on his expertise throughout his explorations, that lack of knowledge of outcome does not diminish the role of expertise in the artist at work. The terms Darwinian and blind mask this and other features of the creative process, and an alternate vocabulary is suggested.     

Picturing the Clima(c)tic: Greenpeace and the Representational Politics of Climate Change Communication

Abstract

The concepts and methods used by regulatory agencies worldwide to assess the safety of flavouring additives were designed by and for the flavouring industry. They embody and embed, in routine regulatory practice, the industry's commercial interests in minimising regulatory costs and the risk that the market for its products might be restricted. First sketched out by US flavouring company scientists in the early 1960s, this approach required almost no experimental data, and was highly permissive, relative to both our knowledge (and lack of it) about chemical toxicity and the ways other kinds of food additives are regulated. A ‘realist constructivist’ analysis illustrates how the industry's approach was also anti-scientific and unscientific because it served to discourage scientific investigation of important aspects of the phenomena it purported to evaluate, and because it relied on assumptions and hypotheses that lacked any evidential basis. The industry approach was first used to assess flavourings in the USA, where the industry was allowed to design and run its own regulatory regime. In all other regulatory jurisdictions, the industry's approach was rejected; expert advisors argued that it was incompatible with mandates to protect consumer health. Yet, the approach eventually prevailed everywhere. It did so in large part because of the collective refusal of the flavouring industry over three decades to provide the experimental data that had been requested by the regulatory authorities. This has been a form of regulatory capture, which was triggered by a remarkably effective tactic of non-cooperation with demands for data.     

Instructive feedback: Effects of number and type

We evaluated the effects of presenting two instructive feedback stimuli of the same and different types for each target behavior taught. Four elementary school students with mild mental retardation were taught to name photographs of places of interest in the local community using constant time delay and instructive feedback. Initially, the four students were taught one set of photographs with one instructive feedback stimulus (name of the street on which the place was located) for each target photograph. All students learned to name all photographs, and three learned to name the street on which the place was located. The three students who learned to name the street for the place in the photograph were then taught three sets of photographs. Each set included two instructive feedback stimuli for each target photograph: Set 2 had one street name and one activity that occurred in the place; Set 3 had two activities per photograph, and Set 4 had one street name and one activity. The three students learned to name the photographs, but only learned to name the activities and not the street names that were presented through instructive feedback. These finds are discussed in terms of the factors that may control acquisition of instructive feedback stimuli and the implications for practice and future research.     

Toward a Transactional Conceptualization of Oppositional Defiant Disorder: Implications for Assessment and Treatment

The conceptualization and treatment of oppositional defiant disorder (ODD) has been characterized by surprising homogeneity. In this paper evidence is presented to underscore the heterogeneity within ODD, including research demonstrating (a) the distinction between reactive and proactive forms of aggression; (b) the importance of affective modulation and self-regulation, and associated cognitive skills, in the development of the skill of compliance; and (c) high levels of comorbidity between ODD and other disorders. The disparate pathways that give rise to oppositional behavior suggest that different children with ODD may require different forms of intervention. The necessity of a transactional conceptualization, of achieving a comprehensive understanding of the factors underlying the difficulties of individual children with ODD, and of matching intervention ingredients to the specific needs of different children and families is discussed.Ross W.

The impact of personality on the reporting of unfounded symptoms and illness.

This study examined the role of personality in the reporting of symptoms and illness not supported by underlying pathology. After assessment of the Big Five personality factors, 276 healthy volunteers were inoculated with a common cold virus. On each of the following 5 days, objective indicators of pathology, self-reported symptoms, and self-reported illness onset were assessed. Neuroticism was directly associated with reports of unfounded (without a physiological basis) symptoms in individuals at baseline and postinoculation in those with and without colds. Neuroticism was also indirectly associated with reports of unfounded illness through reports of more symptoms. Openness to Experience was associated with reporting unfounded symptoms in those with verifiable colds, whereas Conscientiousness was associated with reporting unfounded illness in those who were not ill.
