Temperament in AP Psychology #apexams #appsychology #appsych #learnontiktok

Researchers and psychiatrists Alexander Thomas (1914-2003) and Stella Chess (1914-2007) examined the temperament of young children, suggesting that it was inborn and not learned. Temperament is a measure of a child's activity level, sociability, and emotionality. Variables that are measured in studies to evaluate temperament may include the children's activities, levels of irritability, frequency of smiling, and approach and avoidant postures exhibited.
