Applying signal-detection theory to the study of observer accuracy and bias in behavioral assessment

We evaluated the feasibility and utility of a laboratory model for examining observer accuracy within the framework of signal-detection theory (SDT). Sixty-one individuals collected data on aggression while viewing videotaped segments of simulated teacher-child interactions. The purpose of Experiment 1 was to determine if brief feedback and contingencies for scoring accurately would bias responding reliably. Experiment 2 focused on one variable (specificity of the operational definition) that we hypothesized might decrease the likelihood of bias. The effects of social consequences and information about expected behavior change were examined in Experiment 3. Results indicated that feedback and contingencies reliably biased responding and that the clarity of the definition only moderately affected this outcome.     

Utility of the Multidimensional Health Profile—Psychosocial Functioning Scales (MHP-P) for Assessing Psychosocial Adjustment in Gastric Bypass Surgery Patients

This study examined the utility of the Multidimensional Health Profile—Psychosocial Functioning (MHP-P) for the preoperative assessment of gastric bypass surgery (GBS) applicants. The MHP-P, a 58-item screening inventory that assesses 4 psychosocial areas relevant to health (mental health, life stress, social resources, and coping skills), was administered to 449 morbidly obese patients who were being considered for GBS. Data were compared with the results of a much more lengthy assessment procedure involving a 273-item comprehensive biographical and medical history interview, the MMPI-2, the Basic Personality Inventory, and the Beck Depression Inventory. The 17 measures of the MHP-P showed highly significant correlations with other measures considered to be of relevance in GBS outcome, confirming the utility of the MHP-P as a cost-effective procedure for use in this clinical medical setting.     

Reply to Bermudez and Bonjour

Helen Beebee has recently argued that David Lewis’s account of compatibilism, so-called local miracle compatibilism (LMC), allows for the possibility that agents in deterministic worlds have the ability to break or cause the breaking of a law of nature. Because Lewis’s LMC allows for this consequence, Beebee claims that LMC is untenable and subsequently that Lewis’s criticism of van Inwagen’s Consequence Argument for incompatibilism is substantially weakened. I review Beebee’s argument against Lewis’s thesis and argue that Beebee has not refuted LMC and concomitantly has not demonstrated that Lewis’s criticism of the Consequence Argument fails.     

The Normal,Improving, and Productive Self: Unpacking Neoliberal Governmentality in Therapeutic Interactions

Psychotherapy might be seen as a site of reproduction of neoliberal capitalist ideology. Unpacking therapeutic discourse affords the opportunity to explore neoliberalism in operation. We present a theoretical case for exploring neoliberalism in the therapeutic context. Specifically, we identify and illustrate three neoliberal discourses: the normal self, the improving self, and the productive self. We discuss how therapists might orient to these discourses and identify ways to challenge neoliberal ideology. Doing so will not dismantle power systems that yield oppression; however, it may help clients reclaim and negotiate preferred subjectivities within this system while also working toward broader social justice.     

Comparing Personality Test Formats and Warnings: Effects on criterion‐related validity and test‐taker reactions

The potential for applicant response distortion on personality measures remains a major concern in high‐stakes testing situations. Many approaches to understanding response distortion are too transparent (e.g., instructed faking studies) – or are too subtle (e.g., correlations with social desirability measures as indices of faking). Recent research reveals more promising approaches in two methods: using forced‐choice (FC) personality test items and warning against faking. The present study examined effects of these two methods on criterion‐related validity and test‐taker reactions. Results supported incremental validity for an FC and Likert‐scale measure in warning and no‐warning conditions, above and beyond cognitive ability. No clear differences emerged between the FC vs Likert measures or warning vs no‐warning conditions in terms of validity. However, some evidence suggested that FC measures and warnings may produce negative test‐taker reactions. We conclude with implications for implementation in selection settings.     

Co-creating change within a child protection system: integrating art therapy with family therapy practice

This paper considers family art therapy intervention using a partnership developed between an art therapist and a family therapist within a child protection system. The aim of this co-working relationship is to bring together skills that can amplify the child's voice within the family, using art as a means of extending the family story. The use of metaphor adds to the repertoire of skills available when working with families, and offers a particular form of communication in which children can more easily engage. By co-working, we also bring together our personal and professional stories, creating multiple ideas and ways of seeing and taking account of differences in the life experiences of individual families.     

Why Did They "Choose" to Stay? Perspectives of Hurricane Katrina Observers and Survivors

ABSTRACT— Models of agency—powerful implicit assumptions about what constitutes normatively "good" action—shaped how observers and survivors made meaning after Hurricane Katrina. In Study 1 , we analyzed how 461 observers perceived survivors who evacuated ( leavers ) or stayed ( stayers ) in New Orleans. Observers described leavers positively (as agentic, independent, and in control) and stayers negatively (as passive and lacking agency). Observers' perceptions reflected the disjoint model of agency, which is prevalent in middle-class White contexts and defines "good" actions as those that emanate from within the individual and proactively influence the environment. In Study 2 , we examined interviews with 79 survivors and found that leavers and stayers relied on divergent models of agency. Leavers emphasized independence, choice, and control, whereas stayers emphasized interdependence, strength, and faith. Although both leavers and stayers exercised agency, observers failed to recognize stayers' agency and derogated them because observers assumed that being independent and in control was the only way to be agentic.     

Children’s multiplicative transformations of discrete and continuous quantities

Recent studies have documented an evolutionarily primitive, early emerging cognitive system for the mental representation of numerical quantity (the analog magnitude system). Studies with nonhuman primates, human infants, and preschoolers have shown this system to support computations of numerical ordering, addition, and subtraction involving whole number concepts prior to arithmetic training. Here we report evidence that this system supports children’s predictions about the outcomes of halving and perhaps also doubling transformations. A total of 138 kindergartners and first graders were asked to reason about the quantity resulting from the doubling or halving of an initial numerosity (of a set of dots) or an initial length (of a bar). Controls for dot size, total dot area, and dot density ensured that children were responding to the number of dots in the arrays. Prior to formal instruction in symbolic multiplication, division, or rational number, halving (and perhaps doubling) computations appear to be deployed over discrete and possibly continuous quantities. The ability to apply simple multiplicative transformations to analog magnitude representations of quantity may form a part of the toolkit that children use to construct later concepts of rational number.
