How does Sam feel?: Children's labelling and drawing of basic emotions.

This study compares the ability of children aged from 6 to II to freely produce emotional labels based on detailed scenarios (labelling task), and their ability to depict basic emotions in their human figure drawing (subsequent drawing task). This comparison assesses the relevance of the use of a human figure drawing task in order to test children's comprehension of basic emotions. Such a comparison has never been undertaken up to now, the two tasks being seen as belonging to relatively separate fields of investigation.

[Expression of the emotions in the drawing of a man by the child from 5 to 11 years of age].

This study examines the development of children's ability to express emotions in their human figure drawing. Sixty children of 5, 8, and 11 years were asked to draw "a man," and then a "sad", "happy," "angry" and "surprised" man. Expressivity of the drawings was assessed by means of two procedures: a limited choice and a free labelling procedure.

Representation and performance: reproduction of form and quality of movement in dance by eight- and 11-year-old novices.

This study examined the effects of age on the cognitive representations in modelling. A total of 48 eight- and 11-year-olds were asked to watch a dancer performing a ballet sequence of three steps in order to reproduce it. They were able to see the film as many times as they wanted.

Left cerebral hemisphere hypodensity in discordant schizophrenic twins. A controlled study.

Eleven identical (monozygotic) twin pairs discordant for schizophrenia and 18 unselected control monozygotic twin pairs received a computed tomographic scan. Brain absorption density was determined on quadrants at five slice levels using a fully automatic program that eliminated cerebrospinal fluid spaces from analysis. There was no difference in brain density among schizophrenics, co-twins, and controls.

A fully-automated computer-assisted method of CT brain scan analysis for the measurement of cerebrospinal fluid spaces and brain absorption density.

Computer-assisted methods of CT brain scan analysis offer considerable advantages over visual inspection, particularly in research; and several semi-automated methods are currently available. A new computer-assisted program is presented which provides fully automated processing of CT brain scans, depending on "anatomical knowledge" of where cerebrospinal fluid (CSF)-containing spaces are likely to lie. After identifying these regions of interest quantitative estimates are then provided of CSF content in each slice in cisterns, ventricles, Sylvian fissure and interhemispheric fissure.
