The 20 questions task with families of schizophrenics: divergent findings

The study attempted to replicate and extend the results of an earlier study by Wild and Shapiro (16), establishing the utility of Mosher and Hornsby's (8) 20 Questions Task as a means of differentiating families with schizophrenic patients from those of psychiatrically hospitalized but nonschizophrenic individuals. In the current study, Wild and Shapiro's original design was expanded and revised by (a) diagnosing patients using Research Diagnostic Criteria rather than hospital diagnoses and (b) including families with schizophrenic daughters and/or one-parent families, in addition to intact families with schizophrenic sons. Families were comparable on age, intelligence, and socioeconomic variables. The results failed to replicate those reported by Wild and Shapiro, and indicated that the 20 Questions Task was sensitive to differences in family constellation and offspring gender as well as offspring diagnosis. The findings suggest that forms of familial communication deviance detected with the 20 Questions Task may not be unique to families of schizophrenics, thus highlighting the need to expand research on family communication deviance in families with schizophrenic offspring to families with varied family constellations and characteristics.     

Ability evaluation by proxy: role of maximal performance and related attributes in social comparison

Four experiments tested the effects of information about a proxy's related attributes and maximal effort in social comparisons of ability. In Study 1, a proxy's prior performance at maximal effort exerted systematic effects on participants' personal performance predictions for a novel task. When information about the proxy's effort was ambiguous (Study 2). information about related attribute similarity was used in the formulation of performance predictions. In Studies 3 and 4, 2-way interaction terms revealed that participants used related attribute information in generating performance predictions when the proxy's maximum effort was unknown. However, related attribute information was disregarded when proxy's maximum effort was unambiguous. Results were consistent with the proxy comparison model of ability self-evaluation (L. Wheeler, R. Martin, & J. Suls, 1997).     

Does Anxiety Improve Voters' Decision Making?

Affective Intelligence (AI) theory proposes to answer a fundamental question about democracy: how it succeeds even though most citizens pay little attention to politics. AI contends that, when circumstances generate sufficient anxiety, citizens make informed and thoughtful political decisions. In Ladd and Lenz (2008 ), we showed that two simpler depictions of anxiety's role can explain the vote interactions that apparently support AI. Here, we again replicate Marcus, Neuman and MacKuen's (2000 )'s voting model, which they contend supports AI, and again show that it is vulnerable to these alternative explanations, regardless of how candidate choice is measured. We also briefly review the broader literature and discuss Brader's (2005, 2006 ) important experimental results. Although the literature undoubtedly supports other aspects of AI, few studies directly test AI's voting claims, which were the focus of our reassessment. In our view, the only study that does so while ruling out the two alternatives is our analysis of the 1980 ANES Major Panel ( Ladd & Lenz, 2008 ), which finds no support for AI, but ample support for the alternatives. None of the responses to Ladd and Lenz (2008 ) addresses these findings. Overall, evidence that anxiety helps solve the problem of voter competence remains sparse and vulnerable to alternative explanations.     

Clarifying the Relationship Between Ostracism and Relational Devaluation

We examine how three perspectives on relational devaluation relate to needs threat following ostracism. In two experiments with 179 first-year psychology students, distress was greatest when participants were ostracized without any prior throws, and distress decreased linearly with increasing prior inclusion. In Experiment 3, using 76 first-year psychology students, we manipulated expectations of exclusion and found expectations predicted distress following ostracism, suggesting ostracism's distress can be influenced by norm-based expectations of inclusion, and that progressive relational devaluation is not a necessary condition for ostracism's distress.     

The simultaneous learning effect: why does simultaneous task learning improve retention?

Despite the prevalence of encoding variables that have been shown to influence the rate of learning, very few affect the rate of forgetting of verbal material. However, when a list of words is learned simultaneously with other lists, the rate of forgetting is markedly lower than that of single-task learning. Although the magnitude of this simultaneous learning effect is large compared with typical list learning effects, it has received little empirical attention. Experiments 1 and 2 tested the hypothesis that the simultaneous learning effect is the result of a differential contribution of short-term memory during encoding. The results showed that the advantage for simultaneous task learning was obtained even under conditions that minimized the potential effects of short-term memory. Experiment 3 revealed that the simultaneous learning effect was larger when the specific items learned simultaneously were the same on each learning trial than when they were different. This finding supported a cuing explanation of the effect: the items from the other lists act as retrieval cues during delayed recall.     

Continuous Access to Competing Stimulation as Intervention for Self-Injurious Skin Picking in a Child with Autism

Children with autism frequently display self-injurious behavior (SIB), but skin picking—a less severe topography of SIB—has not been the focus of much clinical research. The present study evaluated a home-based intervention that was implemented with a 9-year-old girl who had autism and picked her fingers with resulting tissue damage. The intervention allowed the girl to hold and manipulate preferred objects during play and leisure activities. Evaluated in an ABAB reversal design, intervention essentially eliminated skin picking. Clinical and research implications are discussed.
