AVOIDANCE STRATEGY USE IN THE INTIMATE RELATIONSHIPS OF WOMEN AND MEN FROM MEXICO AND THE UNITED STATES

Avoidance strategy use refers to the techniques that people use to deal with unwelcome requests from other individuals. Previous research has shown that avoidance strategies in intimate relationships vary along two dimensions: compliance and bilateral dimensions. To determine whether individuals from Mexico and the United States differ in their use of these avoidance strategies with their intimate partners, a study was conducted on males and females from Mexico and the United States. The results indicated that women from the United States reported using more nonverbal disapproval and voices objections types of avoidance strategies with their intimate partners than did women from Mexico and men from both the United States and Mexico. The discussion focuses on the use of social influence strategies among men and women from Mexico and the United States.     

Congruences on Dynamic Algebras

The lattice Cong of all dynamic congruences on a given dynamic algebra is presented. Whenever is separable with zero we define dynamic ideal on , given rise to the lattice Ide. The notions of kernel of a dynamic congruence andthe congruence generated by a dynamic ideal are introduced todescribe a Galois connection between Cong and Ide. We study conditions under which a dynamic congruence is determined byits kernel.     

The detection of temporally defined objects does not require focused attention

Perceptual grouping is crucial to distinguish objects from their background. Recent studies have shown that observers can detect an object that does not have any unique qualities other than unique temporal properties. A crucial question is whether focused attention is needed for this type of grouping. In two visual search experiments, we show that searching for an object defined by temporal grouping can occur in parallel. These findings suggest that focused attention is not needed for temporal grouping to occur. It is proposed that temporal grouping may occur because the neurons representing the changing object elements adopt firing frequencies that cause the visual system to bind these elements together without the need for focused attention.     

Reviewers for Special Issue

Objective: An enhanced stress and coping model was used to explain depression among HIV‐positive women in healthcare and community settings where highly active anti‐retroviral treatment (HAART) was commonplace. Method: HIV‐infected women in four cities (N=978) were assessed, cross‐sectionally, for mental and physical health, stress, social support, and other background factors. Results: Self‐reported level of depressive symptomatology was high. Number of physical symptoms, illness intrusiveness, and perceived stress were positively associated with depressed mood, while coping self‐efficacy and social support were negatively associated. Stress mediated the effect of health status on depression and coping self‐efficacy mediated the effect of psychosocial resources on depression. Our enhanced stress and coping model accounted for 52% of variance in depressive symtpomatology. Conclusions: Interventions focused on improving coping self‐efficacy, bolstering social supports, and decreasing stress in the lives of HIV‐positive women may help to reduce the negative effects of HIV disease on mood.     

Representations of Family Practices, Belief in Sex Differences, and Sexism

Two hundred twenty-one adults and young adults answered one of three versions of a questionnaire of opinion scales, which induced a comparison between three pairs of targets (husband and wife; husband and home helper; wife and home helper). After they evaluated the targets’ contributions to family work, participants judged whether the contributions were fair and satisfactory. Then participants’ degree of belief in sex differences and level of sexism were measured. Results show that spouses’ contributions are only judged satisfactory when wife was compared with home helper; male respondents’ reported that they believed more strongly in sex differences when husband and wife were compared; men’s and women’s level of benevolent sexism did not differ when husband was compared with home helper.     

Self-esteem in body dysmorphic disorder

Although studies indicate that poor body image is associated with poor self-esteem, few investigations have examined self-esteem in a clinical sample of individuals with body dysmorphic disorder (BDD). The present study examined self-esteem in 93 BDD patients and change in self-esteem with pharmacotherapy. Subjects completed the Rosenberg Self-Esteem Scale (RSES) and were assessed with other measures. Participants in a placebo-controlled fluoxetine trial completed measures at baseline and endpoint. The mean RSES score was approximately 1.5 SD units lower than means reported for nonclinical samples. Although poorer self-esteem was associated with more severe BDD and depression, as well as greater delusionality, the relationship between self-esteem and BDD severity was largely mediated by depressive symptoms. Self-esteem did not improve significantly more with fluoxetine than placebo, although it improved significantly more in fluoxetine responders than in nonresponders. It is unclear whether poor self-esteem predisposes to BDD and/or is a consequence of the disorder.     

On the nature and properties of appeals used in direct-to-consumer advertising of prescription drugs

The past decade has seen a steady rise in expenditures for direct-to-consumer pharmaceutical advertising. While total revenues across all media are approaching the $1 billion dollar mark, surprisingly little is known about the effectiveness of these types of advertisements, including the appropriateness of various forms of emotional and informational appeal. A content analysis of direct-to-consumer advertising in 24 popular magazines shows that these advertisements are found in every category of magazine, the advertisements employ a mix of informational and emotional appeals, all types of emotional appeals are used, and to date, the type of appeal (emotional and/or informational) tends not to be based on the type of drug advertised. Implications of this content analysis are considered and directions for research on appeals used in direct-to-consumer advertising are suggested.     

The relative value of two options for pigeons depends on their context

It is well known that when humans are given a choice between two options, their preference is affected by the presence of a third. Generally, there is an increase in preference for the option closer to the third. We show that a shift in preference in the direction away from the third option can occur in animals. We gave pigeons a choice between A, reinforcement following 10 pecks and a 0.5‐s delay, and B, reinforcement following 5 pecks and a 1.5‐s delay. Once stable preferences were established, we introduced a third stimulus, less preferred than the other two: C, reinforcement following 20 pecks and a 0.5‐s delay or D, reinforcement following 5 pecks and a 4.5‐s delay. We found that pigeons presented with C showed an increased preference for B, whereas pigeons presented with D showed an increased preference for A. Our results were consistent with the similarity or attentional hypothesis, which suggests that the third option should interfere with the option more similar to it or would draw attention to the less preferred component of the third option and generalize to the option more similar to it. Possible accounts for the differences in outcomes are suggested.     

Hoarding in obsessive-compulsive disorder: results from the OCD Collaborative Genetics Study

Hoarding behavior occurs frequently in obsessive-compulsive disorder (OCD). Results from previous studies suggest that individuals with OCD who have hoarding symptoms are clinically different than non-hoarders and may represent a distinct clinical group. In the present study, we compared 235 hoarding to 389 non-hoarding participants, all of whom had OCD, collected in the course of the OCD Collaborative Genetics Study. We found that, compared to non-hoarding individuals, hoarders were more likely to have symmetry obsessions and repeating, counting, and ordering compulsions; poorer insight; more severe illness; difficulty initiating or completing tasks; and indecision. Hoarders had a greater prevalence of social phobia and generalized anxiety disorder. Hoarders also had a greater prevalence of obsessive-compulsive and dependent personality disorders. Five personality traits were independently associated with hoarding: miserliness, preoccupation with details, difficulty making decisions, odd behavior or appearance, and magical thinking. Hoarding and indecision were more prevalent in the relatives of hoarding than of non-hoarding probands. Hoarding in relatives was associated with indecision in probands, independently of proband hoarding status. The findings suggest that hoarding behavior may help differentiate a distinct clinical subgroup of people with OCD and may aggregate in some OCD families. Indecision may be a risk factor for hoarding in these families.
