Popis: The effect of the temporal structure of a vocal stimulus on the perception of the emotional component of the signal was studied in several age groups (7–10, 11–13, and 14–17 years). The experiments were performed at different durations of the stimulus (0.5, 1, 1.5, 2, and 3 s). ANOVA of the recognition efficiency and response time showed that the stimulus duration and the interactions of this factor with two others (stimulus duration × age and stimulus duration × emotion type) were highly significant for the recognition of emotions. The effects of the temporal structure of the signal on the recognition efficiency and response time were the strongest in the cases of neutral and negative emotional intonations and on going from the youngest to the middle age group. The minimal stimulus duration at which the threshold recognition of the emotion type occurred changed with age (from 2 s in the youngest age group to 0.5 s in the oldest). The capacity of the sensory acoustic memory was evaluated in children and adolescents of different ages.
