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.     

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.     

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.     

Localizing the development of covert attention in infants with scalp event-related potentials

This study examined covert shifts of attention in infants aged 14, 20, and 26 weeks of age with scalp-recorded event-related potentials (ERPs). The infants were tested in a spatial cuing procedure. The reaction time to localize the target showed covert attention shifts (e.g., response facilitation or inhibition of return depending on cue-target stimulus onset asynchrony). There was a larger P1 ERP component on the valid trials than on the invalid trials or on the no-cue control trials. Presaccadic ERP potentials in response to the target were larger when it was in the cued location than when it was in uncued locations. There were increases from 14 to 26 weeks of age in the amount of inhibition of return, in the post-target-onset P1 effect, and in the presaccadic ERP potentials. These results suggest that cortical development parallels the development of covert orienting of attention and saccade planning in infants in this age range.     

Experimental stimulation by burst-firing weak magnetic fields over the right temporal lobe may facilitate apprehension in women.

Intermittent bursts of weak magnetic fields whose patterns simulate normal amygdaloidal-hippocampal activity were generated by computer over the right or left temporal regions of men and women during partial sensory deprivation. As predicted, women but not men reported greater apprehension during right-hemispheric but not left-hemispheric stimulation. Intrusions of right-hemispheric processes have been hypothesized to affect self-esteem adversely. These results also support the role of the right parahippocampal region in the production of panic attacks.     

Infant attention and the development of smooth pursuit tracking.

The effect of attention on smooth pursuit and saccadic tracking was studied in infants at 8, 14, 20, and 26 weeks of age. A small rectangle was presented moving in a sinusoidal pattern in either the horizontal or vertical direction. Attention level was distinguished with a recording of heart rate. There was an increase across age in overall tracking, the gain of the smooth pursuit eye movements, and an increase in the amplitude of compensatory saccades at faster tracking speeds. One age change was an increase in the preservation of smooth pursuit tracking ability as stimulus speed increased. A second change was the increasing tendency during attentive tracking to shift from smooth pursuit to saccadic tracking when the stimulus speed increased to the highest velocities. This study shows that the development of smooth pursuit and targeted saccadic eye movements is closely related to the development of sustained attention in this age range.     

Delay or probability discounting in a model of impulsive behavior: effect of alcohol

Little is known about the acute effects of drugs of abuse on impulsivity and self-control. In this study, impulsivity was assessed in humans using a computer task that measured delay and probability discounting. Discounting describes how much the value of a reward (or punisher) is decreased when its occurrence is either delayed or uncertain. Twenty-four healthy adult volunteers ingested a moderate dose of ethanol (0.5 or 0.8 g/kg ethanol: n = 12 at each dose) or placebo before completing the discounting task. In the task the participants were given a series of choices between a small, immediate, certain amount of money and $10 that was either delayed (0, 2, 30, 180, or 365 days) or probabilistic (i.e., certainty of receipt was 1.0, .9, .75, .5, or .25). The point at which each individual was indifferent between the smaller immediate or certain reward and the $10 delayed or probabilistic reward was identified using an adjusting-amount procedure. The results indicated that (a) delay and probability discounting were well described by a hyperbolic function; (b) delay and probability discounting were positively correlated within subjects; (c) delay and probability discounting were moderately correlated with personality measures of impulsivity; and (d) alcohol had no effect on discounting.     

The role of parent-adolescent concordance in compliance with cancer chemotherapy

In an attempt to examine factors affecting compliance with orally administered chemotherapy agents, we have examined the relation of agreement of parents and their adolescent children on various treatment-related issues and compliance with cancer chemotherapy. In a longitudinal study, 16 parent/cancer patient pairs were interviewed regarding their knowledge and understanding of illness, medications, and treatment, and their medication compliance. Adolescent responses matched closely those of parents on topics pertaining to medication dose, frequency, number, and purpose. Age was positively correlated with agreement for medication instructions. Disagreements were more commonly found in patients under 17 years of age. Compliance was greater when parents and patients agreed on who was responsible for medication administration, and on their understanding of medication instructions, number, and effectiveness. Treatment of the adolescent oncology patient should include consideration of psychosocial developmental factors, encourage parent-child communication, and place less reliance on self-administered therapy.
