Psychomotor development during treatment of severely marasmic infants.

Previous studies of amlnourished infants have shown that their psychomotor development improves parallel to their nutritional rehabilitation. The present study showed that our patients recovered weight-for-age faster than height-for-age, becoming 42% obese at the end of the treatment. The psychomotor development was also significantly improved, but mainly in social, language and fine coordination areas. The gross motor behaviour did not show any improvement during 5 months of treatment. These results are interpreted in terms of the syndrome of dissociation of maturation.

Neuroticism, extraversion and slow brain potentials.

Peak amplitude and area under the curve of average vertex slow potentials recorded during the foreperiod of a reaction time task were found to discriminate between high- and low-neuroticism subjects, defined according to the Eysenck Personality Inventory. High-neuroticism subjects developed smaller peak amplitude, greater area and longer reaction times, presenting a high extinction rate when the imperative stimulus was omitted. Differences between extraverts and introverts were found within the low-neuroticism group and for area values, extraverts exhibiting larger area. A significant interaction effect of extraversion and neuroticism on slow-potential parameters was evidenced. Results are interpreted in terms of heightened arousal and disrupted focused attention in high-neuroticism subjects. Although evolutionary indexes of slow potentials could differentiate between extraverts and introverts, further work using inhibition indicators is needed to further clarify the differences between them. The data reported also suggest that different aspects of overt behavior would be associated diversely with slow-potential parameters.
