A preliminary study of sex differences in brain activation during a spatial navigation task in healthy adults

The hippocampus plays a significant role in spatial memory processing, with sex differences being prominent on various spatial tasks. This study examined sex differences in healthy adults, using functional magnetic resonance imaging (fMRI) in areas implicated in spatial processing during navigation of a virtual analogue of the Morris water-maze. There were three conditions: learning, hidden, and visible control. There were no significant differences in performance measures. However, sex differences were found in regional brain activation during learning in the right hippocampus, right parahippocampal gyrus, and the cingulate cortex. During the hidden condition, the hippocampus, parahippocampal gyrus, and cingulate cortex were activated in both men and women. Additional brain areas involved in spatial processing may be recruited in women when learning information about the environment, by utilizing external cues (landmarks) more than do men, contributing to the observed sex differences in brain activation.     

Humor as aggression: effects of motivation on hostility expressed in humor appreciation

In 4 studies, the authors examined the hypothesis that relative to primed autonomy motivation, primed control would increase enjoyment of hostile (compared with nonhostile) humor as assessed by self-reported enjoyment and aversiveness and by nonverbal behavior. Results confirmed the hypothesis. Furthermore, initial state hostility moderated the effect such that high-hostility participants who were primed with control motivation especially enjoyed hostile humor. The 2 final studies showed that the effect was mediated by implicit aggression such that the combination of high initial state hostility and control priming led to implicit aggression, which in turn resulted in hostile humor enjoyment. Results are interpreted in terms of the effects of autonomy versus control motivation on intrapersonal self-regulatory processes, which influence interpersonal functioning.     

Relations between Minnesota Multiphasic Personality Inventory-A scales and Rorschach variables with the scope and severity of maltreatment among adolescents

This study examined preexisting Rorschach (Exner, 2001) and Minnesota Multiphasic Personality Inventory-A (MMPI-A; Butcher et al., 1992) profiles to determine if selected MMPI-A scales and Rorschach variables would jointly associate with the number and severity of maltreatment subtypes (physical abuse, sexual abuse, neglect, and emotional maltreatment) of 157 adolescents (ages 14-17) with documented maltreatment histories. The Maltreatment Classification System was used to systematically code the maltreatment attributes. Six Rorschach variables (MOR, PER, Afr, SumY, SumC', Human Content) were significantly correlated with the number of maltreatment subtypes, but none of the anticipated MMPI-A scales were related. MMPI-A Scale 7 and Rorschach variables Ego, MOR, and PER were jointly associated with physical abuse severity. MMPI-A Scale 0 and Rorschach variables MOR, PER, SumY, SumC', PTI, Human Content, and Texture jointly associated with sexual abuse severity. This study supports the potential for certain MMPI-A scales and Rorschach variables to reflect the impact of adolescents' maltreatment experiences in terms of the number and severity of types of maltreatment experienced. Because both instruments captured different aspects of adolescents' maltreatment experiences, clinicians should consider using both when evaluating the impact of maltreatment on adolescents.     

Psychometric properties of the Spanish version of the Collective Efficacy Questionnaire for Sports

The present study analyses the psychometric properties of the Spanish version of the Collective Efficacy Questionnaire in Sports (CEQS). The sample comprises 312 athletes (167 males and 145 females), with a mean age of 24.09 (SD= 6.67), with diverse performance levels (professional, semiprofessional and university level), all practitioners of team sports. The factor structure of the questionnaire was analyzed with confirmatory factor analysis (CFA). The results confirm the 5-factor internal structure of the CESQ (Effort, Ability, Unity, Perseverance and Preparation), made up of four items each. We also found acceptable values of the alpha coefficient, which confirms that the CESQ is a reliable instrument. Lastly, we found preliminary support for the validity of the construct of the CESQ, which is sufficient evidence to justify its use to measure the collective efficacy in Spanish athletes.     

Distinguishing among nondirect forms of aggression

This study explored the relationships and differences among two measures of indirect aggression [Bjorkqvist et al., 1994; Richardson and Green, 1997] and one of relational aggression [Crick and Grotpeter, 1995]. Over 300 students (mean age 22.8 years; 61.5% female) from two colleges in the Southeastern United States completed measures of indirect and relational aggression and related constructs (e.g., empathy, anger expression, direct aggression). Although there were subtle differences among the three measures with regard to their relationships with associated variables, overall the patterns of relationships were similar as well as distinct from the pattern for direct aggression. Factor analysis of scores for measures of aggression revealed that the indirect and relational measures composed a single factor of nondirect aggression, separate from direct aggression. Further factor analysis of all unique items from the nondirect scales found the overall construct of nondirect aggression to comprise six distinct factors. Implications for applications and further research are discussed.     

A dialogue among various cultures and its manifestation in stuttering therapy

This paper presents a historical retrospective of the evolution of the clinical aspects of stuttering, and refers to social, cultural, political, and economic variables that might have exerted an influence on this evolution, particularly in relation to the authors’ experience in Israel. The retrospective commences in the early decades of the 20th century, when speech and language pathology did not exist as a profession, and presents the major approaches to therapy in children and adults employed by clinicians throughout the century. We focused on the impact of the change that occurred in religious society vis-à-vis stuttering on the various aspects of stuttering therapy and research. The Israeli Stuttering Organization - AMBI - is discussed in order to explore the possible influence of social, cultural, and political variables. In addition, we devoted special attention to the changes that occurred in the therapist-client relationship since they are indicative of the change in the nature of the treatment. We elaborated on the need for dialogue as a major component in the therapy and as an important contributor to a successful outcome. The dialogue is also discussed in terms of Eastern philosophy. Future developments in the understanding of stuttering and its implications for therapy are presented and discussed.Educational objectives: The reader will be able to: (1) summarize the history of the clinical development of stuttering and explore the possible influence of social, cultural, political, and economic variables particularly in relation to Israel; (2) provide a new definition of stuttering; and (3) contrast the model of a dialogue as opposed to a monologue and explain its use in the therapist-client relationship.     

Development and Evaluation of a Decision Aid for BRCA Carriers with Breast Cancer

BRCA+ breast cancer patients face high risk for a second breast cancer and ovarian cancer. Helping these women decide among risk-reducing options requires effectively conveying complex, emotionally-laden, information. To support their decision-making needs, we developed a web-based decision aid (DA) as an adjunct to genetic counseling. Phase 1 used focus groups to determine decision-making needs. These findings and the Ottawa Decision Support Framework guided the DA development. Phase 2 involved nine focus groups of four stakeholder types (BRCA+ breast cancer patients, breast cancer advocates, and genetics and oncology professionals) to evaluate the DA's decision-making utility, information content, visual display, and implementation. Overall, feedback was very favorable about the DA, especially a values and preferences ranking-exercise and an output page displaying personalized responses. Stakeholders were divided as to whether the DA should be offered at-home versus only in a clinical setting. This well-received DA will be further tested to determine accessibility and effectiveness.     

The Relation Between Maternal Symptoms of Attention-Deficit/Hyperactivity Disorder and Mother–Infant Interaction

The relationship between maternal symptoms of attention-deficit/hyperactivity disorder (ADHD) and specific maternal behaviors was examined in a community sample of 40 mothers of infants aged 3–8 months. It was hypothesized that maternal ADHD symptoms would be related to lower levels of maternal sensitivity, and higher levels of maternal intrusiveness and negative regard. Mothers and their infants were observed and video-recorded in their homes while interacting in a feeding, play, and task situation. A series of hierarchical regressions partially supported the hypothesized relations: Of the specific maternal ADHD symptoms, maternal inattentive symptoms significantly predicted maternal insensitivity, intrusiveness, and negative regard above and beyond maternal symptoms of anxiety and maternal ratings of infant activity. These findings suggest that mothers reporting ADHD symptoms, particularly the inattentive cluster of symptoms, may experience difficulties in interactions with their infants. Early interventions that address these difficulties may be warranted to facilitate development and reduce the likelihood of adverse outcomes in children of mothers with symptoms of ADHD.     

Immigration, suicidal ideation and deliberate self-injury in the Boston youth survey 2006

The prevalence and immigration-related correlates of deliberate self-injury (DSI) and suicidal ideation (SI) were estimated in a sample of Boston public high school students in 2006. Compared with U.S.-born youth, immigrant youth were not at increased risk for DSI or SI, even if they had experienced discrimination due to their ancestry. By contrast, U.S.-born youth who reported having been discriminated against because of their ancestry had an increased risk of deliberate self-injury (odds ratio [OR] = 3.1, 95% confidence interval [CI] = 1.6-5.9) and suicidal ideation (OR = 2.1, 95% CI = 1.2-3.8). The combination of being U.S.-born and experiencing ancestry-based discrimination identifies youth at increased risk for suicidal behavior.     

Powerful postures versus powerful roles: which is the proximate correlate of thought and behavior?

Three experiments explored whether hierarchical role and body posture have independent or interactive effects on the main outcomes associated with power: action in behavior and abstraction in thought. Although past research has found that being in a powerful role and adopting an expansive body posture can each enhance a sense of power, two experiments showed that when individuals were placed in high- or low-power roles while adopting an expansive or constricted posture, only posture affected the implicit activation of power, the taking of action, and abstraction. However, even though role had a smaller effect on the downstream consequences of power, it had a stronger effect than posture on self-reported sense of power. A final experiment found that posture also had a larger effect on action than recalling an experience of high or low power. We discuss body postures as one of the most proximate correlates of the manifestations of power.
