Volunteer Participation in Context: Motivations and Political Efficacy Within Three AIDS Organizations

Employed quantitative and qualitative data in a contextual examination of participation in three San Francisco-area HIV/AIDS organizations: an urban, gay community-based social change setting; an urban, broadly focused information/referral setting; and a suburban individual support setting. The settings attracted different kinds of volunteers and engaged them differently with the setting, each other, and community. In quantitative analyses external political efficacy (belief in the responsiveness of sociopolitical systems to change efforts) significantly distinguished settings, but was best predicted by setting-moderated relationships to scaled motivations. Qualitative data more clearly illuminated volunteers' motivations for participation, as well as complex, embedded relationships between setting, motivations, attitudes about sociopolitical participation, and personal and community experience and identification. Together the findings underscore three unique but related stories for the three AIDS organizations, and the value of contextual approaches to participation and empowerment.     

Modeling the Role of Child Ethnicity and Gender in Children's Differential Response to Teacher Expectations1

This study examined the relationship between fall teacher expectations and year‐end achievement among 561 children in 1st, 3rd, and 5th grades. Specifically, we hypothesized that children from academically stigmatized groups (African Americans generally and girls in mathematics) are more likely to be responsive to negative teacher expectancies than are children from nonstigmatized groups. Controlling for prior achievement and class membership, moderator effects were tested with hierarchical linear models in the whole sample and with loglinear models in a subsample of children who were targets of extreme teacher over‐ and underestimates of ability. Among targets of extreme teacher over‐ and underestimates, in 3rd and 5th grade, ethnicity moderated expectancy effects in reading; and in 5th grade, gender moderated expectancy effects in math but not reading. Members of stigmatized groups were more susceptible to teacher underestimates of ability. Implications are discussed in terms of differential response to teacher expectations and in terms of how susceptibility to teacher expectations is conceptualized and inferred.     

The stigma of mental illness: Explanatory models and methods for change

For people with mental illness, diminished quality of life and loss of personal goals does not result solely from the symptoms, distress, and disabilities caused by their psychiatric disorder. Quality of life and personal goals are also hindered by people who embrace the stigma that accompanies mental illness and mental health care. This paper reviews evidence of the impact of mental illness stigma and strategies for seeking to ease its impact. To achieve these goals, we (a) describe the ways in which stigma harm people with mental illness, (b) summarize models that explain the development and maintenance of these stigmatizing effects, and (c) review strategies that have been shown to decrease the impact of stigma. Concerns about stigma are on the political agendas of many mental health advocacy groups. It has recently also become the focus of extensive research. Our goal in this paper is to balance the practical concerns raised by mental health advocates against data that support or contradicts specific assertions.     

Culture at work: Family therapy and the culture concept in post-World War II America

During the 1950s and 1960s, the concept of culture had currency beyond the disciplinary boundaries of anthropology and sociology. This article takes up a clinical example of the invocation of the culture concept by examining how early family therapists such as Nathan Ackerman, Murray Bowen, and Don Jackson used culture as a category of analysis during the formative years of their new field. The culture concept played an integral role in the processes by which family therapists simultaneously defined the object of their research and treatment, the family, and built their new field. Their varied uses of culture also contained tensions and contradictions, most notably between universal and relativist views of family and psychopathology and between views of family therapy as a conservative force for maintaining the nuclear family or a progressive force for overcoming social inequality.     

Effects of nonlinguistic auditory variations on lexical processing in Broca's aphasics

In a series of experiments, the effect of white noise distortion and talker variation on lexical access in normal and Broca's aphasic participants was examined using an auditory lexical decision paradigm. Masking the prime stimulus in white noise resulted in reduced semantic priming for both groups, indicating that lexical access is degraded by nonlinguistic white noise distortion. However, talker variation within a prime-target pair had no effect upon the performance of either the normal or aphasic individuals. The absence of a talker variation effect suggests that voice-specific information is not encoded in the lexical representations of words. The normal performance of Broca's aphasics under conditions of both white noise and talker variation supports the view that these patients have a lexical processing impairment rather than a more generalized language deficit characterized by limited computational resources.     

The worried mind: autonomic and prefrontal activation during worrying

To study the psychophysiological correlates of worrying, the authors recorded heart rate, respiratory sinus arrhythmia (RSA), skin conductance level, and alpha electroencephalographic asymmetry in healthy males during baseline, relaxation, worry induction, and anticipation of an impromptu speech task. Compared with baseline, relaxation, and anticipation, worrying was associated with greater heart rate and lower RSA. Worrying was further characterized by higher skin conductance levels compared with baseline but lower levels than during anticipation. Finally, worrying was associated with relatively greater left frontal activity compared with anticipation. Trait public speaking anxiety was positively correlated with left frontal activity during worrying. These results support the notion that worrying is a unique emotional state that is different from fearful anticipation.     

Are creativity and schizotypy products of a right hemisphere bias?

Prior research has shown associations between higher creativity (e.g., semantic association, verbal fluency), higher schizotypy (e.g., magical ideation), and relatively stronger right hemisphere laterality measures--when each of the three pairings has been studied individually. Our prior study related creativity and schizotypy to signal detection theory response criterion aspects of laterality. The present study attempted to integrate findings regarding these three constructs and to replicate the signal detection theory laterality results by providing measures of all three constructs in a within subjects design. Participants were 60 undergraduates who completed a test battery including two measures of creativity, three measures of schizotypy, a lateralized lexical decision task, and a dichotic listening task. Results are consistent with individual differences in creativity and schizotypy being partly related to a response criterion favoring right hemisphere, possibly nonconscious, processing. Dichotic listening results revealed a strong association of better right hemisphere (left ear) localization ability and creativity.
