Associations between serotonin transporter gene promoter region (5-HTTLPR) polymorphism and gaze bias for emotional information

The serotonin transporter promoter region polymorphism (5-HTTLPR) is associated with neural response to negative images in brain regions involved in the experience of emotion. However, the behavioral implications of this sensitivity have been studied far less extensively. The current study used eye-tracking methodology to examine how individuals genotyped for the 5-HTTLPR, including the single nucleotide polymorphism (SNP) rs25531, allocated attention during prolonged (30-s) exposure to face stimuli depicting positive and negative emotion. Short 5-HTTLPR allele carriers and carriers of the long allele with guanine at the sixth nucleotide (S/LG) displayed a stronger gaze bias (total fixation time, number of fixations, mean fixation length) for positive than for sad, threat, or neutral stimuli. In contrast, those homozygous for the long 5-HTTLPR allele with adenine at the sixth nucleotide (LA) viewed the emotion stimuli in an unbiased fashion. Time course analyses indicated no initial 5-HTTLPR group differences; however, S/LG 5-HTTLPR allele carriers were more likely than LA 5-HTTLPR homozygotes to direct gaze toward happy than toward sad stimuli over time. This bias toward positive stimuli during the later stages of information processing likely reflects a strategic effort to downregulate heightened reactivity to negative stimuli among 5-HTTLPR S/LG allele carriers.     

Reduced substance use as a secondary benefit of an indicated cognitive-behavioral adolescent depression prevention program

Our first aim was to test whether a group cognitive-behavioral (CB) depression prevention program reduces substance use escalation over 2-year follow-up relative to two active comparison interventions and a brochure assessment control. Our second aim examined whether reductions in depressive symptoms mediate intervention effects, as posited by the affect-regulation model of substance use. In this indicated prevention trial, 341 high school adolescents at risk for depression because of the presence of elevated depressive symptoms were randomized to a Group CB intervention, group supportive-expressive group intervention, CB bibliotherapy, or educational brochure control condition. Participants in Group CB had significantly lower rates of substance use compared with brochure control participants at both 1- and 2-year follow-up and lower substance use at 2-year follow-up relative to bibliotherapy participants; no other condition differences were significant. Mediational analyses suggested that reductions in depressive symptoms from baseline to posttest accounted for changes in substance use over 2 years for participants in Group CB relative to brochure control participants but did not mediate effects relative to those receiving bibliotherapy. Results suggest that a secondary benefit of this CB group indicated depression prevention program is lower rates of long-term substance use. Findings supported the hypothesis that, relative to a nonactive comparison condition, reductions in depressive symptoms mediated the effects of Group CB prevention on substance use escalation.

When Does Religious Racial Integration “Count?” A Caution About Seeking Ideal Ethnographic Cases

If the particular demographics of attenders, their storied backgrounds, and the peculiar aspects of their social and economic circumstances fail to conform to an “ideal scenario” of “ultimate” diversity, we might find ourselves disappointed. This appears to be one of the most important aspects of Richard Pitt's critique. Pitt desires a different “ideal” case for analysis, a church with black leadership and a clear black dominance that successfully integrates whites. Such an analysis is sorely needed, but this does not reflect the dynamics of Oasis nor does it address what has been one of the most pressing questions among scholars of diversity over the past decade. Given that any black‐white integration is rare, I would not so easily dismiss the specifics of this case. Indeed, rather than merely reverse the case, I want to radicalize the critique. It is time to more purposefully examine diversity beyond the “racial divide,” and I suggest here several ways we can expand the research agenda on diverse congregations.     

Couple Adjustment and Differentiation of Self in the United States,Italy, and Spain: A Cross-Cultural Study

This study comprises a first attempt to explore a cross-cultural application of Bowen family systems theory and examines the relationship between differentiation of self and couple adjustment using measurement invariance. A sample of 2,141 individuals (n = 915 from the United States; n = 635 from Italy; n = 591 from Spain) completed measures of differentiation of self (DSI-R; Skowron & Schmitt, J Marital Fam Ther, 29, 2003, 209) and couple adjustment (DAS; Spanier, J Marriage Fam, 38, 1976, 15). Results showed evidence of partial measurement equivalence for the DSI-R across the three samples. Additionally, results from latent regression showed that less emotional cutoff predicted greater couple adjustment in the United States, Spain, and Italy, whereas greater emotional reactivity predicted poorer couple adjustment only in the more collectivistic cultures, Spain and Italy. Our findings are consistent with prior empirical studies, which suggest that emotional cutoff is a strong predictor of relationship adjustment. The use of measurement invariance provides a foundation for future studies to continue employing rigorous statistical methods when examining constructs across different cultures. The findings highlight culture-specific similarities and differences in differentiation that may benefit practitioners by informing psychotherapy with individuals, couples, or families from diverse populations.     

Evaluation of family structures with figure placement techniques

The relevance of figure placement techniques for analyzing family cohesion and hierarchy structures in various settings is described and the completion of further studies including these instruments is suggested.     

The Effects of Self-Correction Versus Traditional Spelling on the Spelling Performance and Maintenance of Third Grade Students

We examined the effect of self-correction versus a traditional spelling approach on the acquisition and maintenance of written spelling of elementary school students enrolled in third grade. Six students, who were at risk for spelling failure, served as subjects. During self-correction, students used a form with five columns that contained correct pre-written models of spelling words. After reviewing the word list, students folded back the first column, which contained the words. Then, they listened to their spelling list on individual cassette players and spelled each word in turn in the subsequent columns of the form. Students checked their spelling responses by unfolding the first column and matching their responses to the sample. Each correct spelling response was marked with a C incorrect spellings were fixed by writing the correct orthography above the word. During traditional spelling, students wrote each spelling word five times, using a pre-written model as a guide. Results showed a functional relationship between self-correction and improved spelling performance. Five of the six maintained a higher number of posttests words on maintenance probes. All students preferred the self-correction method over the traditional spelling method.     

A comparison of female and male adolescents' social behaviors and cognitions: A challenge to the assertiveness literature

Sex differences were investigated in the thoughts and behaviors of adolescents in simulated social situations. The pattern of sex differences indicated females to be more appropriately assertive in their overt behaviors than males. Males were more aggressive. In their cognitions females were more likely to deny their impact on others, while males were more likely to deny the impact of others on themselves. Potency training was suggested for females, assertiveness training for males. Cluster analyses of correlations among behaviors and thoughts revealed four clusters for females: external locus of control, internal locus of control, active expressiveness, and social isolation or denial. The three male clusters were a negative impotent one, a positive active cluster, and an aggressive hostile cluster.The research reported is based on a dissertation submitted in partial fulfillment of the requirements for a Ph.D., University of Toronto (OISE). The research was partially funded by OISE Research and Development Grant No. 3478, awarded to the second author.
