Vanryckeghem & Brutten’s age groups were not specified by months, and may, therefore, slightly differ from the age groups in the present study. In the present study, children in the younger age group were between the ages of 36 – 54 months; the older age group consisted of children between the ages of 55 – 71 months. Vanryckeghem & Brutten’s younger group included children 3 to 4 years of age, whereas the older group consisted of children 5 – 6 years of age.

These “raw” or descriptive M and SD will be slightly different from the estimated marginal mean (EM) and standard error estimate (SEE) used in the inferential statistical modeling reported in the Results section.
