The purposes of the present study were to clarify the relationship between the characteristics of conversation in meals and parent-child psychological connection, and to investigate its developmental differences between elementary school and senior school children. The questionnaire was distributed to 140 families composed of fifth or sixth grade children and their parents, and 245 families composed of senior high school children and their parents. The main results were as follows: (1) Elementary school children and their fathers, and senior high school children and their parents in higher levels of psychological connection had more positive and frequent conversations with family members in meals, after meals and at different mealtime than ones in lower levels. Elementary school children's mothers in higher levels of psychological connection had more frequent conversations with children in meal and at different mealtime than ones in lower levels. (2) Senior high school children in higher levels of psychological connection with their fathers took meals together more frequently than the ones in lower levels. It was suggested that positive and frequent conversations in meals had a important role for parent-child psychological connection in early and middle adolescence.
