A Study of Black and White College Women

In an examination of career aspirations, 101 black and 530 white college women were asked to indicate their occupational and educational plans, important considerations for career choices, and their attitudes toward combining the roles of career and family. Results indicated that women who planned careers in male-dominated occupations had higher career and educational aspirations than women who desired careers in femaledominated occupations. Black women who planned careers in male-dominated professions showed high levels of aspirations, planned more education than was necessary for the desired occupations, and perceived less conflict in combining the roles of career and family than their white counterparts. There were few differences between black and white women in their attitudes toward the traditional roles of men and women. Those choosing female-dominated careers, however, had more traditional attitudes regardless of race. Implications of these findings for the influence of occupational gender dominance on career aspirations are discussed.     

Toward Developing Laboratory-Based Parent–Adolescent Conflict Discussion Tasks that Consistently Elicit Adolescent Conflict-Related Stress Responses: Support from Physiology and Observed Behavior

Parent–adolescent conflict poses risk for youth maladjustment. One potential mechanism of this risk is that stress in the form of increased arousal during conflict interactions results in adolescents’ impaired decision-making. However, eliciting consistent adolescent stress responses within laboratory-based tasks of parent–adolescent conflict (i.e., conflict discussion tasks) is hindered by task design. This limitation may stem from how conflict topics are assessed and selected for discussion. Within a sample of 47 adolescents (ages 14–17) and parents, we investigated whether a modified version of a conflict discussion task could elicit physiological (i.e., arousal) and behavioral (i.e., hostility) displays of adolescents’ conflict-related stress responses. We assessed parent–adolescent conflict via structured interview to identify topics for dyads to discuss during the task. We randomly assigned dyads to complete a 5-min task to discuss either a putatively benign topic (i.e., control condition) or a conflict topic while undergoing direct assessments of continuous arousal. Trained raters coded dyad members’ hostile behavior during the task. Adolescents in the conflict condition exhibited significantly greater levels of arousal than adolescents in the control condition. We observed an interaction between discussion condition and baseline conflict. Specifically, higher baseline conflict predicted greater hostile behavior for adolescents in the conflict condition, yet we observed the inverse relation for adolescents in the control condition. Our modified laboratory discussion task successfully elicited both physiological and behavioral displays of adolescent conflict-related stress. These findings have important implications for leveraging experimental paradigms to understand causal links between parent–adolescent conflict and adolescent psychopathology, and their underlying mechanisms.     

Study of behavioural and neural bases of visuo‐spatial working memory with an fMRI paradigm based on an n‐back task

The goal of this study was to propose a new functional magnetic resonance imaging (fMRI) paradigm using a language‐free adaptation of a 2‐back working memory task to avoid cultural and educational bias. We additionally provide an index of the validity of the proposed paradigm and test whether the experimental task discriminates the behavioural performances of healthy participants from those of individuals with working memory deficits. Ten healthy participants and nine patients presenting working memory (WM) deficits due to acquired brain injury (ABI) performed the developed task. To inspect whether the paradigm activates brain areas typically involved in visual working memory (VWM), brain activation of the healthy participants was assessed with fMRIs. To examine the task's capacity to discriminate behavioural data, performances of the healthy participants in the task were compared with those of ABI patients. Data were analysed with GLM‐based random effects procedures and t‐tests. We found an increase of the BOLD signal in the specialized areas of VWM. Concerning behavioural performances, healthy participants showed the predicted pattern of more hits, less omissions and a tendency for fewer false alarms, more self‐corrected responses, and faster reaction times, when compared with subjects presenting WM impairments. The results suggest that this task activates brain areas involved in VWM and discriminates behavioural performances of clinical and non‐clinical groups. It can thus be used as a research methodology for behavioural and neuroimaging studies of VWM in block‐design paradigms.     

Dualism and its Importance for Medicine

Cartesian dualism has been viewed by medical theorists to be oneof the chief causes of a reductionist/mechanistic treatment ofthe patient. Although I aver that Cartesian dualism is one culprit for the misapprehension of the genuine treatment of patients in termsof both mind and body, I argue that interactive dualism whichstresses the interaction of mind and body is essential to treatpatients with dignity and compassion. Thus, adequate medical carethat is humanistic in nature is difficult (if not impossible)to achieve without physicians adhering to a dualistic frameworkin which the body and person is treated during illness.     

Perceptions of the parent-adolescent relationship: a longitudinal investigation

A self-report measure of conflict and aspects of warmth in the parent-child relationship was completed by 1,330 11-year-old twins, 1,176 of whom completed the inventory again 3 years later. On average, adolescents' perceptions of the quality of the parent-child relationship declined consistently and moderately between age 11 and age 14. Conflict with parents increased, whereas all aspects of warmth decreased; changes were significantly greater for girls than boys. Variances increased with age, primarily because of increases in the magnitude of genetic effects. Heritability estimates ranged from .09 to .31 at intake and .35 to .45 at follow-up and tended to be higher for boys than girls. Changes in the parent-child relationship are interpreted as reflecting genotype-environment correlation processes whereby adolescents increasingly influence their relationships with their parents.     

Bayesian eggs and Bayesian omelettes: reply to Stern (2005)

In this response to Stern's (2005) discussion of Klugkist, Laudy, and Hoijtink (2005), model inference based on posterior probabilities on the parameter space is discussed. Furthermore, the authors respond to Stern's example in which all possible orderings are included via a short discussion of exploratory versus theory-based modeling. Finally, the authors show that the Bayesian approach is flexible and can deal with many types of constraints. This is illustrated using a model with constraints on the differences between means.     

Teachers' screening for attention deficit/hyperactivity disorder: comparing multinational samples on teacher ratings of ADHD

This study evaluates a measurement model for Attention Deficit/Hyperactivity Disorder (ADHD). The DSM-IV divides 18 symptoms into two groups, inattentive and hyperactive/impulsive. Elementary school teachers rated 21,161 children in 4 locations: Spain, Germany, urban US, and suburban US. Confirmatory factor analysis suggested that the 2-factor model (inattention, hyperactivity/impulsivity) shows the best fit. A third factor, impulsivity, was too slight to stand-alone. Children with academic performance problems were distinguished by inattention, but children with behavior problems typically had elevations in inattention, hyperactivity, and impulsivity. Between-site differences were statistically significant, but so small that we conclude that same measurement model fits all 4 samples in 2 continents.     

Professional efficacy,exhaustion, and work characteristics among police officers: A longitudinal test of the learning‐related predictions of the demand—control model

The present study addressed the relationships among professional efficacy, emotional exhaustion, and job characteristics (job demands and job control) in the context of a two‐wave panel study among 828 Dutch police officers. Based on the demand–control model, we expected that high demands/high control would be positively related to professional efficacy, and that high demands/low control would be related to high levels of exhaustion. Moreover, we hypothesized that high levels of exhaustion would lead to lower levels of professional efficacy and that high levels of efficacy would lead to low levels of exhaustion. Structural equation modelling largely supported these predictions. High demands were longitudinally related to high levels of efficacy and high levels of exhaustion; high control was longitudinally related to high levels of efficacy. Further, efficacy and exhaustion were indeed mutually related. Finally, high levels of exhaustion were longitudinally related to high levels of demands. We conclude that there are complex, yet theoretically, and practically interpretable relations among efficacy, strain and work characteristics.
