[Early stimulation: 10 years' experience].

Infancy psychomotor yield in lower socioeconomic levels can be damaged from the first year of life. This implies future consequences to individuals, family-and society. Early stimulation programs have demonstrated to improve psychomotor yield in the above mentioned children. In Temuco, Chile, in groups of children with different risks, that were incorporated to an early stimulation program, it has been seen that the lower the birth weight the greater the risk of future psychomotor deterioration, which is also true for children that survived neonatal meningitis. On the other hand, in children that presented hyperbilirubinemia, low Apgar scores and neonatal septicemia, no significant statistical differences in psychomotor development have been observed in comparison with those of similar birthweight but without these antecedents. In this study the Chilean Health Ministry's Evaluation and Psychomotor Stimulation Program is reviewed as to adapt it for children at greatest risk.

[Reaction time measures in depressed patients].

The work presented below is enclosed in a research on depressive retardation in children. It deals with the measurement of reaction time to sensori stimuli (visual or auditory) among children from 7 to 13 year old. Patients with major depressive episode were presented twice, before medication and at their discharge. The assessment which is performed to the nearest thousandth of a second thanks to a program developed on micro computer includes 5 test situations: 1. simple visual stimulation; 2. simple auditory stimulation; 3. choice situation between visual and auditory stimulation; 4. unlocated visual stimulation; 5. choice situation between two different visual stimulations. Generally speaking the best scores are logically achieved for the simple auditory tests followed by the simple visual test. The highest scores almost systematically appear for the test offering the choice between two different visual stimulations. For each of the five tests the values are always correlated between the two passation periods. These correlations mean that the passation time depends on each child. Those who achieved "good scores" in the depression phase before medication are the same who achieve good scores at their discharge and vice versa. These performances have no relation either with the age of the children. The analysis of the results brings out two factors: For simple stimuli tests, performances do not vary between the two passation periods and therefore show a motor normal function. On the other hand, for tests which involve a choice (and therefore decision making) before medication children react significantly more slowly than after improvement.(ABSTRACT TRUNCATED AT 250 WORDS)

[Behavioral differences in childhood depression: study of blinking and auto-manipulation].

Different investigations have studied the evolution of childhood depression but little research has been based on the observation of behavior. This work aims at analysing two singular behaviors: eye blink and auto-manipulation. This paper compares the results obtained on day A(hospital admission, before treatment) and on day D (discharge, after clinical improvement) during a standardized interview recorded in video with children aged 8-13 years, hospitalized for a major depressive episode and for a control group. The results show a significant decrease in eye blink frequency and the mean auto-manipulation duration after clinical improvement. The discussion raises the question of the role of anxiety in the development of these behavioral modifications.
