Use of a differential observing response to expand restricted stimulus control

This study extends previous work on the use of differential observing responses (DOR) to remediate atypically restricted stimulus control. A participant with autism had high matching-to-sample accuracy scores with printed words that had no letters in common (e.g., cat, lid, bug) but poor accuracy with words that had two letters in common (e.g., cat, can, car). In the DOR intervention, she matched the distinguishing letters of the overlapping words (e.g., t, n, r) immediately prior to matching the whole words. Accuracy scores improved, and accuracy remained high when DOR requirements were withdrawn.     

Infidelity, race, and gender: An evolutionary perspective on asymmetries in subjective distress to violations-of-trust

Asymmetries in subjective distress were observed among African American and white (N = 191) men and women who were asked to imagine a partner being emotionally and sexually unfaithful, and a partner committing other paired, gender-linked viola-tions-of-trust. More women than men were distressed by imagining a partner forming a deep emotional attachment to another person and more men than women were distressed by imagining a partner enjoying passionate sexual intercourse with another person. In addition, more men than women were distressed by male-linked violations, such as a partner no longer trying to look attractive, and more women than men were distressed by female-linked violations, such as a partner no longer wanting to work. The results contribute to a growing body of cross-cultural research reporting gender differences in distress to emotional and sexual infidelity. The results also provide cross-cultural validation of the extension of an evolutionary perspective to under-standing gender differences in subjective distress to other biologically relevant viola-tions-of-trust.     

Church-based health behavior programs: Using social cognitive theory to formulate interventions for at-risk populations

Epidemiological analyses conclude that the major contributors to all-cause premature mortality and morbidity are smoking, alcohol abuse, inappropriate diet, and a sedentary lifestyle. Efforts to modify these health behaviors in populations with community and worksite interventions, although initially promising, have had difficulty in sustaining health-behavior changes. More intensive, theoretically based interventions targeted to at-risk groups and delivered in smaller social units, such as churches and other religious organizations, have been recommended. An intervention based on social cognitive theory that entails integrating self-regulatory procedures with social and environmental supports in rural churches serving people from lower socioeconomic groups is described in detail.     

Number comparison and number ordering as predictors of arithmetic performance in adults: Exploring the link between the two skills,and investigating the question of domain-specificity

Recent evidence has highlighted the important role that number-ordering skills play in arithmetic abilities, both in children and adults. In the current study, we demonstrated that number comparison and ordering skills were both significantly related to arithmetic performance in adults, and the effect size was greater in the case of ordering skills. Additionally, we found that the effect of number comparison skills on arithmetic performance was mediated by number-ordering skills. Moreover, performance on comparison and ordering tasks involving the months of the year was also strongly correlated with arithmetic skills, and participants displayed similar (canonical or reverse) distance effects on the comparison and ordering tasks involving months as when the tasks included numbers. This suggests that the processes responsible for the link between comparison and ordering skills and arithmetic performance are not specific to the domain of numbers. Finally, a factor analysis indicated that performance on comparison and ordering tasks loaded on a factor that included performance on a number line task and self-reported spatial thinking styles. These results substantially extend previous research on the role of order processing abilities in mental arithmetic.     

Queering Bem: Theoretical Intersections Between Sandra Bem’s Scholarship and Queer Theory

Sandra Bem revolutionized psychology with her research on gender, androgyny, and gender schematicity, which culminated in her book, The Lenses of Gender. Her work also provides a model for how to cross inter-disciplinary lines to enhance scholarship and reach political goals. We analyze similarities and differences between Bem’s scholarship and scholarship in queer theory, a theoretical movement in the humanities that analyzes discourses that construct man/woman and straight/gay binaries. There are important overlaps between Bem’s lenses of gender (biological essentialism, gender polarization, and androcentrism) and the ideas of many queer theorists. There are also several interesting differences between Bem’s ideas and queer theory: attention to the intrapsychic processes that make up gender, the extent to which individuals can be liberated from gender, proliferating versus contesting gender, intersectionality, and epistemology and methodology. By assessing the similarities and differences between Bem and queer theorists, we show that the two complement each other, affording a better understanding of gender and sexuality. Additionally, both Bem and queer theory lend insight into feminist and queer activism. The theoretical and political advances that can be made by integrating Bem’s ideas and those of queer theorists serve as examples for why it is worthwhile to cross disciplinary lines.     

Modifying Obsessive-Compulsive Beliefs about Controlling One’s Thoughts

Cognitive models of obsessive-compulsive disorder propose that beliefs about the importance of and need to control thoughts (ICT) are central to the maintenance of the disorder. Cognitive Bias Modification for Interpretation (CBM-I) can be used to experimentally test this theory and may also have clinical utility as an adjunct therapeutic tool. The current study extended previous research to investigate whether two CBM-I sessions (one within and one outside the laboratory) would augment effects on obsessive-compulsive beliefs and behavior. We randomly allocated undergraduate participants high in ICT beliefs to a Positive (n = 30) or Control (n = 36) CBM-I condition and conducted multi-modal assessments immediately following the first training and at one-week follow-up. As predicted, participants in the Positive condition reported a reduction in obsessive-compulsive beliefs from baseline to follow-up (partial η ² = .42), whereas those in the Control condition did not. Participants responded more adaptively to the ICT relevant stressor task at follow-up compared to post-intervention, but there was no significant difference between conditions. Likewise, participants reported a reduction in obsessive symptoms over time that did not differ between conditions. The findings are considered in light of cognitive models of OCD, and clinical implications are discussed.     

Comprehension of Idioms by Children with Learning Disabilities: Metaphoric Transparency and Syntactic Frozenness

Third and fifth grade children with and without learning disabilities participated in this study. Syntactically frozen and flexible idioms and transparent and opaque idioms were used as stimuli to examine the ability to identify the correct idiom and to explain idiom meanings. Grade and diagnostic category affected performance on the explanation task but not on the forced choice task. Idiom type was also a factor affecting comprehension and explanation. Literal responses occurred rarely and were more likely to occur on the forced choice task.     

Representation and execution of vocal motor programs for expert singing of tonal melodies

Three experiments were conducted to study motor programs used by expert singers to produce short tonal melodies. Each experiment involved a response-priming procedure in which singers prepared to sing a primary melody but on 50% of trials had to switch and sing a different (secondary) melody instead. In Experiment 1, secondary melodies in the same key as the primary melody were easier to produce than secondary melodies in a different key. Experiment 2 showed that it was the initial note rather than key per se that affected production of secondary melodies. In Experiment 3, secondary melodies involving exact transpositions were easier to sing than secondary melodies with a different contour than the primary melody. Also, switches between the keys of C and G were easier than those between C and E. Taken together, these results suggest that the initial note of a melody may be the most important element in the motor program, that key is represented in a hierarchical form, and that melodic contour is represented as a series of exact semitone offsets.
