Expressed emotion attitudes and individual psychopathology among the relatives of bipolar patients

This study investigated the relationships between expressed emotion (EE) and individual psychopathology among 82 biological and non-biological relatives of 66 patients with bipolar I disorder. Relatives' psychopathology was assessed via the Structured Clinical Interview for DSM-III-R, Patient Version (SCID-P) and the General Behavior Inventory (GBI), a self-report measure of lifetime subsyndromal mood disturbances. We hypothesized that relatives who held high-EE critical, hostile, and/or overinvolved attitudes toward their bipolar family member, as measured via the Camberwell Family Interview, would be more likely to have DSM-III-R Axis I diagnoses on the SCID, as well as more mood and temperamental disturbances on the GBI, than those who held low-EE attitudes. The findings did not support a significant relationship between overall EE status and psychopathology in family members. However, relatives without significant Axis I pathology scored significantly higher than those with Axis I pathology on one measure of EE, emotional overinvolvement. The findings are discussed with reference to explanations for the genesis of high-EE attitudes.     

Driving anger and other driving-related behaviors in high and low ADHD symptom college students

This study examined differences between college students with high and low symptoms of Attention-Deficit/Hyperactivity Disorder (ADHD). Fifty-nine introductory psychology students completed ADHD diagnostic measures and were compared on measures of driving anger and driving anger expression; accident-related, aggressive, and risky driving behaviors; general anger; and general anger expression. Results indicated high ADHD symptom college students experience more driving anger, display such anger in more hostile/aggressive ways, are more aggressive and risky on the road, experience more crash-related outcomes, are more generally angry, and tend to display anger in socially unacceptable ways. Results are discussed in regard to the understanding and treatment of ADHD.     

The Probability of Collective Choice with Shared Knowledge Structures

Complex decision making typically involves many agents attempting to aggregate many alternatives. If agents' preferences are unconstrained, cyclic outcomes are highly probable. In contrast, we show that if agents share similar models of the choice domain, then a stable collective outcome occurs with about 90% probability. These results have implications for systems of interacting agents, such as group decisions by individuals in social settings or interpretations of sense data by competing perceptual modules of a brain.     

Attention affects the recognition of briefly presented visual stimuli in infants: an ERP study

This study examined the effect of attention in infants on the ERP changes occurring during the recognition of briefly presented visual stimuli. Infants at ages 4.5, 6 and 7.5 months were presented with a Sesame Street movie that elicited periods of attention and inattention, and computer-generated stimuli were presented overlaid on the movie for 500 ms. One stimulus was familiar to the infants and was presented frequently, a second stimulus was familiar but presented infrequently, and a set of 14 novel stimuli were presented infrequently. An ERP component labeled the 'Nc' (Negative Central, about 450-550 ms after stimulus onset) was larger during attention than inattention and increased in magnitude over the three testing ages during attention. Late slow waves in the ERP (from 1000 to 2000 ms post-stimulus onset) consisted of a positive slow wave in response to the infrequent familiar stimulus at all three testing ages. The late slow wave in response to the infrequent novel stimulus during attention was a positive slow wave for the 4.5-month-old infants, to a positive-negative slow wave for the 6-month-old infants and a negative slow wave for the 7.5-month-old infants. These results show attention facilitates the brain response during infant recognition memory and show that developmental changes in recognition memory are closely related to changes in attention.     

Internet-based treatment for panic disorder

Increasingly, the internet is being used as a source of mental health information as well as structured treatment programs for people with mental health concerns or problems. The present review focuses mainly on research conducted at the University of Ballarat in Australia, and Uppsala University in Sweden, on internet-based treatment for panic disorder, one of the more common and disabling anxiety disorders. Our studies suggest that internet-based cognitive behavioural therapy is an effective intervention for panic disorder, and that it is more effective than some other self-help therapies. We have found that this mode of intervention is associated with clinically significant change, improved psychological well-being and functioning, and low participant attrition, provided that timely, limited therapist assistance is also provided. This review also discusses treatment credibility and participant satisfaction, as well as assessment and crisis management issues. Although promising as a form of intervention, there is a need for more research on the efficacy of internet-based treatment for PD and on comparisons with evidence-based face-to-face therapies.     

Anger,aggression, and risky behavior: a comparison of high and low anger drivers

This research tested hypotheses from state-trait anger theory applied to anger while driving. High and low anger drivers drove equally often and as many miles, but high anger drivers reported more frequent and intense anger and more aggression and risky behavior in daily driving, greater anger in frequently occurring situations, more frequent close calls and moving violations, and greater use of hostile/aggressive and less adaptive/constructive ways of expressing anger. In low impedance simulations, groups did not differ on state anger or aggression; however, high anger drivers reported greater state anger and verbal and physical aggression in high impedance simulations. High anger drivers drove at higher speeds in low impedance simulations and had shorter times and distances to collision and were twice as likely to crash in high impedance simulations. Additionally, high anger drivers were more generally angry. Hypotheses were generally supported, and few gender differences were noted for anger and aggression.     

A fresh look at perversion

The history of ideas about perversion is considered, along with an examination of whether the concept is clinically useful. Three cases of varying degrees of severity are presented, illustrating the clinical value of the concept in the analytic situation. All three cases are women, and the particular usefulness of the concept of perversion for women is noted. The place of aggression and the pleasure resulting from its expression are highlighted.
