EVALUATION AND TRAINING OF YES‐NO RESPONDING ACROSS VERBAL OPERANTS

Topographically similar verbal responses may be functionally independent forms of operant behavior. For example, saying yes or no may have different functions based on the environmental conditions in effect. The present study extends previous research on both the assessment and acquisition of yes and no responses across contexts in children with language deficits and further examined the functional independence of topographically similar responses. All participants in the present study acquired yes and no responses within verbal operants (e.g., mands). However, generalization of the responses across novel verbal operants (e.g., tacts to intraverbals) did not occur without additional training, thus supporting Skinner's (1957) assertion of functional independence of verbal operants.     

Homelessness in the US and Germany: a cross‐national analysis

A public opinion survey was administered by telephone to nationally representative samples in the US and Germany to assess prevalence of homelessness as well as attitudes, opinions and knowledge regarding homelessness. Lower prevalence rates were found in Germany as compared with the US. German respondents demonstrated higher levels of general compassion, greater support for the public rights of the homeless, a greater tendency to view the homeless as trustworthy, and were more likely to view economic factors and less likely to view personal failings as integral to the problem of homelessness. Respondent age, gender, and political affiliation predicted many public opinion variables. Copyright © 2003 John Wiley & Sons, Ltd.     

Comorbid anxiety and mood disorders among persons with social anxiety disorder.

Axis I comorbidity is associated with greater severity of social anxiety disorder. However, the differential effects of comorbid mood and anxiety disorders on symptom severity or treatment outcome have not been investigated. We evaluated 69 persons with uncomplicated social anxiety disorder, 39 persons with an additional anxiety disorder, and 33 persons with an additional mood disorder (with or without additional anxiety disorders). Those with comorbid mood disorders reported greater duration of social anxiety than those with uncomplicated social anxiety disorder. They were also judged, before and after 12 weeks of cognitive-behavioral group treatment and at follow-up, to be more severely impaired than those with no comorbid diagnosis. In contrast, persons with comorbid anxiety disorders were rated as more impaired than those with no comorbid diagnosis on only a single measure. Type of comorbid diagnosis did not result in differential rates of improvement of social anxiety disorder.     

Parenting and attachment among toddlers with congenital anomalies: Examining the Strange Situation and attachment Q‐sort

This study assessed parent and child predictors of attachment in a sample of 72 toddlers with neurological (e.g., cerebral palsy) and non‐neurological (e.g., cleft lip and palate) birth defects and their mothers. Parenting quality (e.g., sensitivity) was expected to be more important in predicting the attachment relationship than type and severity of child medical condition. Parenting and indices of severity of child condition were measured via researcher observation. Attachment was measured via the Strange Situation and parent reported Attachment Q‐sort. Parenting quality was better for children with more severe appearance disfigurements. Strange Situation and Q‐sort assessments of attachment were not significantly related. Children with neurological impairments were at greater risk for developing insecure attachments than were children with non‐neurological conditions. Parenting quality also directly predicted Strange Situation assessed attachment security and Q‐sort comfort seeking/exploration but not standard Q‐sort criterion scores. Parenting quality partially mediated the relation between child medical condition and attachment security. Results suggest child medical factors influence parenting, and thereby, child attachment. ©2002 Michigan Association for Infant Mental Health.     

Political Philosophy: The View from Cambridge

This article reports on a conversation convened by Quentin Skinner at the invitation of the Editors of The Journal of Political Philosophy and held in Cambridge on 13 February 2001.     

Reaping the Rewards of Diversity: The Role of Identity Integration

How does diversity affect individuals and the groups in which they are embedded? This article examines this question using recent theory and research on Identity Integration (II). II refers to an individual's perceptions about whether two distinct social identities, or social groups to which individuals belong, are viewed as compatible (high II) or not (low II). A review of extant research suggests that individuals with high II are better at simultaneously accessing multiple identities and identity‐related knowledge and have improved well‐being and social outcomes. Expanding on this work, we argue that individuals who have higher II, and social collectives that foster II within their members, are more likely to reap the benefits of diversity.     

Increased associated movements: influence of attention deficits and movement difficulties

This study was designed to examine whether increased associated movements (AMs) reflect motor difficulties or the symptoms associated with attention disorders. Four groups of male children (N=51) aged 6-8 years participated: Group 1 consisted of 13 children diagnosed with developmental coordination disorder (DCD); Group 2 consisted of 13 children diagnosed with attention deficit hyperactivity disorder (ADHD); Group 3 consisted of 10 children diagnosed with co-occurring DCD and ADHD, and Group 4 was a control sample of 15 children, with no known movement or attention difficulties. Various AM tasks were selected from established assessments and previous research to measure AM severity. The results supported the hypothesis that increased severity of AMs reflect movement difficulties with children in the DCD and DCD/ADHD groups displaying significantly more AMs than children in the ADHD and control groups (p<.001). No differences were found between the ADHD only and control groups (p=.67) or the DCD and DCD/ADHD groups (p=.81) suggesting that AM severity is not influenced by the neurodevelopmental symptoms associated with ADHD.     

Arousal, processing, and risk taking: consequences of intergroup anger

Intergroup emotions theory (IET) posits that when social categorization is salient, individuals feel the same emotions as others who share their group membership. Extensive research supporting this proposition has relied heavily on self-reports of group-based emotions. In three experiments, the authors provide converging evidence that group-based anger has subtle and less explicitly controlled consequences for information processing, using measures that do not rely on self-reported emotional experience. Specifically, the authors show that intergroup anger involves arousal (Experiment 1), reduces systematic processing of persuasive messages (Experiment 2), is moderated by group identification (Experiment 2, posttest), and compared to intergroup fear, increases risk taking (Experiment 3). These findings provide converging evidence that consistent with IET, emotions triggered by social categorization have psychologically consequential effects and are not evident solely in self-reports.     

Endorsing a negative in-group stereotype as a self-protective strategy: Sacrificing the group to save the self

This work examined if stigmatized targets will embrace negative in-group stereotypes in order to protect their self-esteem from the threat of stereotypic failures. All studies focused on the stereotype that women have lower math ability than men. In Study 1, women who failed a math test showed buffered self-esteem if they were first given the opportunity to endorse this stereotype. Study 2 replicated this effect and showed that women, but not men, increased their endorsement of this stereotype following math failure. Study 3 showed that the tendency to embrace this stereotype in response to failure was most pronounced among women with high trait self-esteem. Together, these findings suggest that there are contexts in which stigmatized individuals can protect their self-esteem in the face of stereotypic failures by embracing the very stereotypes that would have predicted their failure.
