Dr. Beatrice conducted an observational study to investigate the relationship between the duration of day care attendance and cooperative behaviour in preschool children.
She recruited her participants from parents and their three-year-old children who were attending a Saturday morning family music session at a local public library.
She compared two groups of three-year-olds:
During a scheduled free-play session in the library hall, Beatrice paired each participant with an unfamiliar peer and provided a limited set of popular toys. She observed each child's interactions for 5 minutes and rated their cooperative behaviour. She used a scale of 1 to 10, where a score of 1 indicated 'highly aggressive/no sharing' and a score of 10 indicated 'highly cooperative/spontaneous sharing'.
