[Psychophysiological studies in the pre-school children]

Area of Science:

• Pediatric cardiology and developmental psychology.
• Investigating physiological responses in young children during educational activities.

Context:

• Preschool children (aged 3-6 years) participated in two distinct 90-minute educational programs: 'Didactic games' and an 'Elementary music and movement program'.
• Behavioral observations were video-recorded, and electrocardiograms (ECGs) were telemetrically monitored simultaneously.

Purpose:

• To correlate heart rate and motor activity in children during different preschool educational settings.
• To analyze variations in heart rate, including respiratory arrhythmias, and signs of exertion in relation to program type and cardiovascular stability.

Summary:

• Mean heart rate was higher during the music program, correlating with increased motor activity.
• The didactic program showed greater heart rate variability due to respiratory arrhythmias, particularly when children exhibited fatigue.
• Children displayed fewer signs of exertion during the music program compared to the didactic program.

Impact:

• Findings suggest that different preschool programs elicit distinct physiological responses in young children.
• Highlights the potential for music and movement programs to be less physically taxing than didactic games.
• Identifies respiratory arrhythmias as a potential indicator of fatigue or cardiovascular stress in children during educational activities.
