title: Age, gender, and interpersonal behavior development using the FIRO-BC.
abstract: It has been argued that many human behaviors follow predictable developmental patterns, or stages. The FIRO-BC was given to 9- through 13-year-old children (n = 282) to test for a stage-like progression in interpersonal behavior development. The data presented here failed to evidence an age-related progression. However, gender differences did appear in 11-year-olds and increased dramatically by age 13. Geographical differences were found in that the present data differed significantly from the normative data presented in the FIRO manual. The data also support the notion that, at least within the southern population tested. interpersonal behavior may be more related to puberty than has been previously supposed.
