The psychophysics of contingency assessment

The authors previously described a procedure that permits rapid, multiple within-participant evaluations of contingency assessment (the "streamed-trial" procedure, M. J. C. Crump, S. D. Hannah, L. G. Allan, & L. K. Hord, 2007). In the present experiments, they used the streamed-trial procedure, combined with the method of constant stimuli and a binary classification response, to assess the psychophysics of contingency assessment. This strategy provides a methodology for evaluating whether variations in contingency assessment reflect changes in the participant's sensitivity to the contingency or changes in the participant's response bias (or decision criterion). The sign of the contingency (positive or negative), outcome density, and imposition of an explicit payoff structure had little influence on sensitivity to contingencies but did influence the decision criterion. The authors discuss how a psychophysical analysis can provide a better understanding of findings in the literature such as mood and age effects on contingency assessment. They also discuss the relation between a psychophysical approach and an associative account of contingency assessment.     

Clinical considerations for the treatment of body dysmorphic disorder with cognitive-behavioral therapy

Although cognitive behavior therapy has been found to be very effective in the treatment of body dysmorphic disorder (BDD), there still remain a number of challenges that clinicians face in the treatment of individuals with BDD. In this article, we discuss issues related to comorbid depression, suicidality, substance use disorders, personality disorders as well as the role of early life experiences, delusional intensity of beliefs, and motivation to change. The aim of this review is to provide a treatment aid to clinicians by offering specific recommendations for improved care based on the available literature as well as our clinical experience.     

Granny, (don't) get your gun: competency issues in gun ownership by older adults

This article explores the possible risks associated with gun ownership by older adults. We summarize existing regulations on who may own firearms, especially with respect to age. We then present data on older gun owners and violence committed by older adults in general, followed by a discussion of gun violence perpetrated by gun owners whose functional and cognitive abilities have declined, perhaps as a result of dementia. For comparison purposes, we review regulations on driving among older adults, drawing parallels to gun ownership. The paper concludes with recommendations for ensuring the safety of older gun owners and others, balanced against citizens' right to bear arms, and with some directions for research.     

Contingency judgements on the fly

The present research was conducted to establish the validity of a novel procedure for measuring human contingency judgements aimed at shortening the length of conventional procedures. Cues and outcomes were simple geometric shapes that were presented in a rapid streaming fashion, reducing the length of a block of trials from several minutes to a few seconds. We establish the reliability of the procedure by replicating two central findings in the contingency judgement literature, and we elaborate on the importance of this method for future research.     

The influence of gender and ethnicity on children's peer collaborations

Gender and ethnicity are important aspects of children's everyday social relationships, yet little is known about how these social categories influence children's collaborative interactions. In the present study, 322 White (Caucasian) and South Asian boys and girls (mean age, 7.5 years) collaborated in pairs on easy and difficult versions of a model completion task. As expected, girls were less assertive than boys in conversation, yet this relation held only for all‐Asian pairs (i.e., an Asian boy and girl in conversation). Also consistent with expectations, levels of conversational affiliation were lowest in cross‐ethnic interaction. The influence of gender and ethnicity on conversations did not vary in light of contrasting cognitive demands of the tasks. Results are discussed in relation to work on effective peer collaboration and the potential role of contact in promoting positive ethnic and gender group attitudes.     

Counsellors' experiences of changing their practice: Learning the psychodynamic‐interpersonal model of therapy

Seven counsellors were interviewed about their experiences of learning and applying a new approach to therapy: the psychodynamic‐interpersonal model. These interviews were analysed using grounded theory — a qualitative approach. Under the core category of ‘changing counselling practice: applying the PI model of therapy’, the material was organised into 10 major categories: difficult feelings; new awareness; therapeutic identity; identifying reasons for choosing how to work; experiencing difficulties in adherence; attributing causes of difficulties; ways through the difficulties; understanding how change in practice occurs; changing interventions; and specific other inputs. Examples from the interviews are used to cast light on the difficulties experienced by counsellors in the process of changing their practice.     

Why are you looking at me? It’s because I’m talking,but mostly because I’m staring or not doing much

Our attention is particularly driven toward faces, especially the eyes, and there is much debate over the factors that modulate this social attentional orienting. Most of the previous research has presented faces in isolation, and we tried to address this shortcoming by measuring people’s eye movements whilst they observe more naturalistic and varied social interactions. Participants’ eye movements were monitored whilst they watched three different types of social interactions (monologue, manual activity, active attentional misdirection), which were either accompanied by the corresponding audio as speech or by silence. Our results showed that (1) participants spent more time looking at the face when the person was giving a monologue, than when he/she was carrying out manual activities, and in the latter case they spent more time fixating on the person’s hands. (2) Hearing speech significantly increases the amount of time participants spent looking at the face (this effect was relatively small), although this was not accounted for by any increase in mouth-oriented gaze. (3) Participants spent significantly more time fixating on the face when direct eye contact was established, and this drive to establish eye contact was significantly stronger in the manual activities than during the monologue. These results highlight people’s strategic top-down control over when they attend to faces and the eyes, and support the view that we use our eyes to signal non-verbal information.
