Attentional Performance in Children and Adolescents with Tic Disorder and Co-Occurring Attention-Deficit/Hyperactivity Disorder: New Insights from a 2 × 2 Factorial Design Study

The aim of the present study was to investigate the effect of both tic disorder (TD) and attention-deficit/hyperactivity disorder (ADHD) on attentional functions. N = 96 children and adolescents participated in the study, including n = 21 subjects with TD, n = 23 subjects with ADHD, n = 25 subjects with TD+ADHD, and n = 27 controls. Attentional performance was tested based on four computerized attention tasks (sustained attention, divided attention, go/nogo and set shifting). The effect of TD as well as ADHD on attentional performance was tested using a 2 × 2 factorial approach. A diagnosis of TD had no negative impact on attentional functions but was associated with improved performance in the set shifting task. By contrast, regardless of a diagnosis of TD, subjects with ADHD were found to perform worse in the sustained attention, divided attention and go/nogo task. No interaction effect between the factors TD and ADHD was revealed for any of the attention measures. Our results add to findings from other areas of research, showing that in subjects with TD and ADHD, ADHD psychopathology is often the main source of impairment, whereas a diagnosis of TD has little or no impact on neuropsychological performance in most cases and even seems to be associated with adaptive mechanisms.     

Desirability of the Bem Sex-Role Inventory Items for Women and Men: A Comparison Between African Americans and European Americans

The Bem Sex-Role Inventory (BSRI) is a widely used instrument for measuring gender role perceptions, but questions have been raised regarding whether its items reflect contemporary views on gender. A recent study (Holt & Ellis, 1998) revalidated all but 2 of the 40 adjectives included in the masculine and feminine BSRI indices for a predominantly European American undergraduate sample in a rural Southern town. We examined whether European Americans in a different geographical area and 2 samples of African Americans would show similar findings. Study participants were recruited in undergraduate management courses in 2 universities and included 62 European American women, 69 European American men, 40 African American women, and 31 African American men in a large Northeastern city and 56 African American women and 33 African American men in a small Southern city. Findings indicated that European American men in the urban Northeast and African American men in the South gave the most traditional ratings, whereas European American women in the urban Northeast expressed the most liberal views. European American women considered only 4 of the 40 BSRI items to be differentially desirable for women and men, a considerable departure from the findings of Holt and Ellis (1998) as well as Bem (1974).     

Gender Role Attitudes and Careers: A Longitudinal Study

Data from the Monitoring the Future Study were used to examine the impact of early gender role attitudes on later career outcomes for women and men. We also examined the impact of marriage, children, and labor market outcomes on changes in gender role attitudes. Women’s early gender role attitudes predicted their later work hours and earnings. Women’s work hours predicted their later gender egalitarianism. Children were negatively associated with later gender egalitarianism for both women and men. Findings indicated that gender role attitudes influence subsequent behavior, but they may also be adjusted to accommodate to situational constraints.     

The association between life events and suicide intent in self-poisoners with and without a history of deliberate self-harm: a preliminary study

The associations between life events in the 12 months preceding an episode of self-poisoning resulting in hospital attendance (the index episode), and the suicide intent of this episode were compared in individuals for whom the index episode was their first, episode and in individuals in whom it was a recurrence of DSH. Results indicated a significant interaction between independent life events, repetition status, and gender in the prediction of suicide intent, the association between life events and intent being moderated by repetition status in women only. The results provide preliminary evidence to suggest the presence of a suicidal process in women, in which the impact of negative life events on suicide intent diminishes across episodes.     

Emotional irritation before mental stress is associated with enhanced peripheral norepinephrine

Research suggests equivocal findings on associations of catecholamines and mood. Our study investigated the associations of emotional state, blood pressure and catecholamines in 55 healthy males undergoing mental stress. We especially checked the reported link between norepinephrine (NE) and emotional irritation. Blood pressure (SBP, DBP) and heart rate (HR) were continuously monitored. NE and epinephrine (EPI) were measured before, after, and 20 minutes after stress. Participants were divided into irritated versus non-irritated and anxious versus non-anxious subjects by median split on their baseline questionnaires. The task elicited significant cardiovascular, hormonal, and psychological stress responses. NE levels were significantly correlated with irritation before stress. Irritated subjects showed significantly higher DBP and NE than non-irritated subjects. The higher NE and DBP levels in the irritated participants suggest detrimental psycho-physiological interrelations promoting the development of stress-mediated cardiovascular diseases. Heightened emotional irritation before stress may be regarded as a psychological risk factor.
