Gender-Role Cognition in Three-Year-Old Boys and Girls

Although the multidimensionality of gender roles has been well established, few researchers have investigated male and female roles separately. Because of the substantial differences in the ways male and female roles are portrayed in our culture, boys and girls may think and learn about these roles differently. The male role is more clearly defined, more highly valued, and more salient than the female role; thus, children's cognitions about these two roles may be expected to differ. The present study addressed the question of whether there is sex-typical variation in gender labeling, gender-role knowledge, and schematicity. Participants were 120 families; 15% were from minority ethnic groups, and 17% were single-parent families; 25% of the parents had a high school education or less. Results indicated that at 36 months of age, boys were less able to label gender and less knowledgeable about gender roles than were girls. Boys' knew more about male stereotypes than female stereotypes, whereas girls knew considerably more than boys about the female role and as much as boys about the male role. Boys and girls were found to be similar in gender schematicity. Traditionality of parental attitudes regarding child-rearing and maternal employment were not strongly related to children's gender cognition.     

Validating self-report measures of state and trait anxiety against a physiological measure

While anxiety research frequently uses only self-report measures to assess dimensions of state and trait anxiety, the present study sought to corroborate these self-report measures using a physiological measure, namely heart rate. Another aim of the present study was to test the multidimensional interaction model of anxiety in a social evalua-tion situation (i.e., a seminar presentation), using a physiological measure of state anxiety. Graduate psychology students completed a state anxiety questionnaire and were attached to a heart rate recorder prior to a class seminar presentation. One week later, students completed trait and state anxiety questionnaires and were again at-tached to a heart rate recorder prior to seminar observation by others. Heart rate was elevated during seminar presentation relative to seminar observation, reached maxi-mum values during the first 15 minutes of seminar presentation and then decreased over time. State anxiety scores indicate that participants were experiencing consider-ably more anxiety just before presenting the seminar than just before observing a seminar. Heart rate during seminar presentation was significantly correlated with self-report state anxiety and self-report social evaluation trait anxiety, but not with seminar grade. Support was found for the multidimensional interaction model of anxiety using the physiological measure (i.e., heart rate).

ORGANON The Web Tutor for Basic Logic Courses

We would like to introduce the web tutor ORGANON, which aimsto support basic logic courses at the University of West Bohemiain Pilsen (Czech Republic). The application was designed tofulfill two requirements. Firstly, it should help students duringtheir study to practice exercises on their own (providing permanentcontrol during students’ practicing exercises as wellas answering students’ questions immediately as they arise).Secondly, it should reduce teachers’ burden (diminishingthe amount of consultations as well as administrating students’homework including correcting and grading). The tutor is availableat http://kfi.zcu.cz/lide/dostalova/organon.     

White-matter microstructure and language lateralization in left-handers: A whole-brain MRI analysis

Most people are left-hemisphere dominant for language. However the neuroanatomy of language lateralization is not fully understood. By combining functional magnetic resonance imaging (fMRI) and diffusion tensor imaging (DTI), we studied whether language lateralization is associated with cerebral white-matter (WM) microstructure. Sixteen healthy, left-handed women aged 20–25 were included in the study. Left-handers were targeted in order to increase the chances of involving subjects with atypical language lateralization. Language lateralization was determined by fMRI using a verbal fluency paradigm. Tract-based spatial statistics analysis of DTI data was applied to test for WM microstructural correlates of language lateralization across the whole brain. Fractional anisotropy and mean diffusivity were used as indicators of WM microstructural organization. Right-hemispheric language dominance was associated with reduced microstructural integrity of the left superior longitudinal fasciculus and left-sided parietal lobe WM. In left-handed women, reduced integrity of the left-sided language related tracts may be closely linked to the development of right hemispheric language dominance. Our results may offer new insights into language lateralization and structure–function relationships in human language system.     

Procedural and Distributive Justice Beliefs for Self and Others: Multilevel Associations with Life Satisfaction and Self-Rated Health

Personal happiness and well-being are associated with a dispositional tendency to believe in the existence of justice. In addition, research suggests that links between justice beliefs and well-being are best revealed when utilizing distinctions between a belief in justice for one’s self versus others, and also a belief in procedural versus distributive justice. Using multilevel modeling, we examined whether individual-level links to personal well-being are moderated by higher-order (county-level) justice climates. Michigan (United States) residents (N = 497) were recruited through a statewide survey to complete measures of procedural and distributive justice beliefs for self and others, life satisfaction, and self-rated health. Individual-level beliefs in justice for both self and for others were more strongly associated with life satisfaction and health in climates where beliefs about justice for others were robust. In addition, an individual-level belief in distributive justice was more strongly linked to self-rated health in high distributive justice climates, and in low procedural justice climates. Taken together, these cross-level interactions suggest that higher-order justice climates may alter relationships between individual-level justice beliefs and personal well-being. We discuss implications for justice theory and directions for continued research on well-being and happiness.     

Early cessation success or failure among women attempting to quit smoking: trajectories and volatility of urge and negative mood during the first postcessation week

Aversive symptoms of abstinence from nicotine have been posited to lead to smoking relapse and research on temporal patterns of abstinence symptoms confirms this assumption. However, little is known about the association of symptom trajectories early after quitting with postcessation smoking or about the differential effects of tonic (background) versus phasic (temptation-related) symptom trajectories on smoking status. The current study examined trajectories of urge and negative mood among 300 women using the nicotine patch during the first postcessation week. Ecological momentary assessments collected randomly and during temptation episodes were analyzed using hierarchical linear modeling yielding four individual trajectory parameters: intercept (initial symptom level), linear slope (direction and rate of change), quadratic coefficient (curvature), and volatility (scatter). Early lapsers, who lapsed during the first postcessation week, exhibited more severe tonic urge and phasic negative mood immediately after quitting, and more volatile tonic and phasic urge compared to abstainers. Late lapsers, who were abstinent during the first week but lapsed by 1 month, exhibited more severe tonic urge immediately after quitting compared to abstainers. These results demonstrate the importance of early postcessation urge and negative affect and highlight the value of examining both tonic and phasic effects of abstinence from nicotine.     

Emotional Dysregulation and Interpersonal Difficulties as Risk Factors for Nonsuicidal Self-Injury in Adolescent Girls

The purpose of this study was to examine a model of factors that place psychiatrically hospitalized girls at risk for non-suicidal self-injury (NSSI). The role of familial and peer interpersonal difficulties, as well as emotional dysregulation, were examined in relationship to NSSI behaviors. Participants were 99 adolescent girls (83.2% Caucasian; M age = 16.08) admitted to a psychiatric hospital. Structural equation modeling indicated the primacy of emotional dysregulation as an underlying process placing adolescents at risk for NSSI and mediating the influence of interpersonal problems through the family and peer domains. When family and peer relationships were characterized by conflict and lack of support for managing emotions, adolescents reported more dysregulated emotion processes. Family relational problems were directly and indirectly related to NSSI through emotional dysregulation. The indirect processes of peer relational problems, through emotional dysregulation, were significantly associated with NSSI frequency and severity. The findings suggest that the process by which interpersonal difficulties contribute to NSSI is complex, and is at least partially dependent on the nature of the interpersonal problems and emotion processes.     

Reduced electroencephalographic coherence asymmetry in the Chernobyl accident survivors

An electroencephalograph (EEG) study was carried out from 1990 to 2006, using power spectra, averaged coherence, and integral EEG coherence asymmetry coefficients to compare 189 clean-up workers of the Chernobyl accident with 63 age-matched healthy controls. Most of the Chernobyl workers showed three abnormal EEG patterns, as indicated by EEG power mapping. The higher power, most prominent in slow alpha and theta bands, or in fast alpha frequencies, were observed in persons 3-5 years after the clean-up works (the early stage). The lower EEG power in alpha band was found in Chernobyl workers 10 or more years after the accident (the late stage). EEG coherence analysis revealed the existence of two stages in EEG alterations following the Chernobyl clean-up. In the early stage, an increase of EEG coherence in the central brain areas was observed, whereas at the later stage, a decrease of EEG coherence, most prominent in the frontal brain areas, and reduced brain asymmetry prevailed. These results allow us to propose that the described EEG signs may be a reflection of radiation-induced brain dysfunction at the late period after the Chernobyl clean-up and were similar to the EEG markers of brain ageing. The results, in comparison to data of the literature, provide additional support to the premature brain ageing hypothesis in Chernobyl survivors as a result of the radiation brain damage after-effect.     

The Beck Anxiety Inventory-Trait (BAIT): a measure of dispositional anxiety not contaminated by dispositional depression

We describe development of the Beck Anxiety Inventory-Trait (BAIT), a measure of trait anxiety. In Study 1 with 191 undergraduates, the BAIT correlated higher with another trait-anxiety measure than with state anxiety and trait depressiveness and lower with depressiveness than the other trait-anxiety measure did. In Study 2 (Ns of 149 undergraduates initially and 107 at 3 weeks later), the BAIT demonstrated convergent validity against the Beck Anxiety Inventory (BAI; Beck, Epstein, Brown, & Steer, 1988) and self-rated trait anxiety plus discriminant validity against abstract curiosity. In Study 3 (Ns of 161 undergraduates initially and 121 at 3 weeks later), the BAIT correlated more highly with another anxiety measure than with depression, stress, positive affect, and negative affect. It also showed good internal consistency across studies and high stability in Studies 2 and 3, higher than the BAI's in Study 2. Factor analyses across studies all supported 2 factors, 1 Somatic and 1 Subjective.
