Assessment and treatment of problem behavior occasioned by interruption of free-operant behavior

The current study describes the assessment and treatment of the problem behavior of 3 individuals with autism for whom initial functional analysis results were inconclusive. Subsequent analyses revealed that the interruption of free-operant behavior using "do" requests (Study 1) as well as "do" and "don't" requests (Study 2) occasioned problem behavior. Initially, treatment involved differential and noncontingent reinforcement without interruption. To make the intervention more sustainable in the natural environment (where interruptions are unavoidable), a two-component multiple-schedule arrangement was used to progressively increase the period of time in which ongoing activities would be interrupted. During generalization sessions, the intervention was applied across a variety of contexts and therapists.     

A Big Regulatory Tool-Box for a Small Technology

There is little doubt that the development and commercialisation of nanotechnologies is challenging traditional state-based regulatory regimes. Yet governments currently appear to be taking a non-interventionist approach to directly regulating this emerging technology. This paper argues that a large regulatory toolbox is available for governing this small technology and that as nanotechnologies evolve, many regulatory advances are likely to occur outside of government. It notes the scientific uncertainties facing us as we contemplate nanotechnology regulatory matters and then examines the notion of regulation itself, suggesting new ways to frame our understanding of both regulation and the regulatory tools relevant to nanotechnologies. By drawing upon three different conceptual lenses of regulation, the paper articulates a wide range of potential regulatory tools at hand. It also focuses particularly on the ways various tools are currently being used or perhaps may be employed in the future. The strengths and weaknesses characterising these tools is examined as well as the different actors involved. The paper concludes that we will increasingly face debate over what is likely to work most effectively in regulating nano technologies, the legitimacy of these different potential approaches, and the speed at which these different regimes may be employed.

Assessing normative approaches to communicating violence risk: a national survey of psychologists

There is growing attention to the importance of violence risk communication, and emerging empirical evidence of how evaluating clinicians who conduct risk assessments communicate their conclusions about the risk of violence toward others. The present study addressed the perceived value of different forms of risk communication through a national survey of practicing psychologists (N = 1,000). Responses were received from a total of 256 participants, who responded to eight vignettes in which three factors relevant to risk communication were systematically varied in a 2 x 2 x 2 within-subjects design, counterbalanced for order: (i) risk model (prediction oriented versus management oriented), (ii) risk level (high risk versus low risk), and (iii) risk factors (static versus dynamic). Participants were asked to rate the value of six styles of risk communication for each of eight vignettes. The most highly valued style of risk communication involved identifying risk factors applicable to the individual, and specifying interventions to reduce risk. These results were consistent with findings from several previous studies in this area, and reflect an emerging trend in preferences for style and context of risk communication of violence.     

Observed increases in positive affect during behavioral treatment

A 15‐year‐old female diagnosed with mental retardation was admitted to an inpatient facility for the assessment and treatment of a severe behavior disorder. A behavioral treatment to reduce destructive behavior consisting of enriched environment, differential reinforcement, and time‐out was evaluated in a reversal design. Data on affect were collected during baseline and treatment phases. In addition to achieving clinically significant reductions in problem behavior, collateral improvements in positive affect were observed during treatment phases.

Prime and prejudice: Brief stereotypical media representations can increase prejudicial attitudes and behaviour towards people with schizophrenia

Prejudice against people with mental illnesses remains a significant problem in the United Kingdom and in many other countries despite sustained efforts by governments and charities. This is particularly so for people with schizophrenia, who are seen as dangerous and unpredictable. The present study investigated the effect of brief, casual, stereotypical representations on prejudice and behavioural intentions towards people with schizophrenia. Participants viewed Halloween costumes in an online environment under the guise of product research. In the experimental condition, they were exposed to a “Psycho Ward” Halloween outfit identical to one sold online by a leading supermarket chain in the United Kingdom. Participants in the control condition saw a neutral “pumpkin” Halloween costume. Exposure to the Psycho Ward outfit resulted in more negative behavioural intentions towards people with schizophrenia, mediated by increased prejudice. These findings confirm and extend earlier research that implicates adverse media stereotypes in the persistence of prejudice against people with mental illness. More research is warranted on the relative effects of different influences on community attitudes to mental illness.     

Children's event reports: Factors affecting responses to repeated questions in vignette scenarios and event recall interviews

When adults repeat questions, children often give inconsistent answers. This study aimed to test the claim that these inconsistencies occur because children infer that their first answer was unsatisfactory, and that the adult expects them to change their answer. Children aged 4, 6, and 8 years (N= 134) were asked about vignettes in which an adult repeated a question, with manipulation of the adult's overt dissatisfaction (high vs. low pressure) and knowledge about the information sought. On a separate occasion, the children were given an unrelated event recall interview containing repeated questions. All age groups showed sensitivity to adult dissatisfaction, interpreting question repetition as an implicit request for answer change more frequently in the high than in the low‐pressure vignettes. Overall, however, these ‘change‐expected’ interpretations were least frequent in the younger children, who were the most prone to shifting. Also there was no evidence that these interpretations were associated with more frequent shifting in the recall interview. The results do not provide clear support for a simple conversational inference account of shifting, especially in younger children.
