Development of children's understanding of connections between thinking and feeling.

Two studies assessed the development of children's understanding that thoughts and feelings are closely interlinked. These studies showed that, unlike 8-year-olds and adults, 5-year-olds seldom explained a sudden change in emotion that had no apparent external cause by appeal to the occurrence of a thought. They also tended not to recognize that a person who is feeling sad is probably also thinking sad thoughts, or that people may be able to make themselves feel happy just by thinking of something happy. These results are consistent with evidence that young children tend to be unaware of the stream of consciousness and have poor introspective skills. A possible developmental sequence leading to an understanding of these thought-feeling links is proposed.
