Duration of flooding sessions in the treatment of obsessive-compulsive patients

This study investigated the duration effect of flooding ‘in vivo’ and ‘in fantasy’ in twelve obsessive-compulsive patients treated in a balanced Latin square design. Clinical assessments regarding twenty one clinical variables were carried out before and after each treatment condition. Long practice sessions proved significantly superior to other treatment conditions. Short and long sessions ‘in fantasy’ did not diner significantly. Long fantasy sessions appear to have potentiating effects on in vivo practice sessions. The order effect and the intercorrelation of the variables prior to treatment and to the outcome, are also presented. Some prognostic factors and the follow-up findings are discussed.     

The import of infancy for individual, family, and societal development: commentary on the special section: does infancy matter?

Across their life spans humans actualize a rich potential for cognitive and behavioral plasticity, a set of developmental changes that require regulation of organism-context relations on the part of both the individual and society. An individual’s action on the context must be started in infancy and maintained in subsequent periods of life for adaptive functioning to occur across ontogeny. The process of the individual acting as an agent of his or her own development is continuous, although the particular ways in which such control is manifested will change in developmentally appropriate ways. As demonstrated by the papers in this special issue, the significance of infancy for the rest of the life-span rests on an integration of this continuity and discontinuity within the person-context developmental system.     

The Interference of Introversion–Extraversion and Depressive Symptomatology with Reasoning Performance: A Behavioural Study

The objective of this study was to investigate the link between the Eysenck Personality Questionnaire (EPQ) scores and depressive symptomatology with reasoning performance induced by a task including valid and invalid Aristotelian syllogisms. The EPQ and the Zung Depressive Scale (ZDS) were completed by 48 healthy subjects (27 male, 21 female) aged 33.5 ± 9.0 years. Additionally, the subjects engaged into two reasoning tasks (valid vs. invalid syllogisms). Analysis showed that the judgment of invalid syllogisms is a more difficult task than of valid judgments (65.1% vs. 74.6% of correct judgments respectively, p < 0.01). In both conditions, the subjects’ degree of confidence is significantly higher when they make a correct judgment than when they make an incorrect judgment (83.8 ± 11.2 vs. 75.3 ± 17.3, p < 0.01). Subjects with extraversion as measured by EPQ and high sexual desire as rated by the relative ZDS subscale are more prone to make incorrect judgments in the valid syllogisms, while, at the same time, they are more confident in their responses. The effects of extraversion/introversion and sexual desire on the outcome measures of the valid condition are not commutative but additive. These findings indicate that extraversion/introversion and sexual desire variations may have a detrimental effect in the reasoning performance.     

Psychophysiological responses in obsessive-compulsive patients

Psychophysiological measures (pulse rate and skin conductance) and subjective anxiety ratings were taken in twelve obsessive-compulsive patients, during internal and external stimulation. Five identical assessments were carried out on each patient, prior to any treatment and shortly after the following flooding technique variants: short fantasy, long fantasy, short practice and long practice.Internal and. or external anxiety-provoking stimulation produced significantly, greater autonomie activity than neutral stimulation in almost all measures, before treatment. The difference became less significant or disappeared in some measures after treatment, and in particular after long flooding in practice. The internally elicited arousal by self-induced obsessive imagery was more resistant to change than externally elicited arousal. Heart rate showed the least decrement after treatment. Some prognostic variables are presented.     

Pre-morbid personality traits and responsiveness to flooding in obsessive-compulsive patients

Clinical and psychophysiological assessments were carried out before and after completion of flooding treatment in two groups of obsessive-compulsive patients, matched for age and duration of the illness but differing in pre-morbid obsessional personality traits.

Patients with such traits appear to demonstrate a specific autonomic sensitivity to flooding, probably related to either the reduction of anxiety after treatment or to certain qualities of the treatment itself. Significant changes after treatment regarding neutral stimuli and attitude ratings of untreated obsessional manifestations suggest a more global response to flooding in such patients.

Some suggestions for further research are presented.
