The effects of spatial task performance on heart rate characteristics were studied taking into account nonverbal intelligence and autonomic balance. Males and females with low nonverbal intelligence according to the Raven test were mostly sympathicotonics, while subjects with high intelligence were mostly vagotonics. A specific emotional response was observed in females with low and high nonverbal IQs immediately after the task completion and increased the stress index (SI). This clearly suggested that the task was stressful for them. Males with low and high nonverbal IQs were characterized by a reduction of the SI, indicating that this task activity was adequate for male subjects.
