This observational study assessed the relation between affective behavior and linguistic complexity in mother-son dyads. The participants were eight dyads mother-son, four children were 3 -years-olds and four 5 -years-old. Dyads were videotaped 30 minutes while they interacted in two conditions, free play and pretend play. For analysis functional complexity and affective behavior were identified, 20 minutes were codified. The results show that some categories of positive affective behavior are related to the children age, play situation, and the child and mother behavioral complexity. The data are discussed in terms of conditions under which it is more likely the occurrence of positive affective behavior and its importance for child behavior complexity.
