The Measurement of Self-Regulation from Ages 2 to 8

The development of the capacity for self-regulation represents a major achievement of childhood that is associated with social, behavioural and academic competence. Most research has focused on self-regulated academic learning in school-aged children and adolescents, neglecting developmental aspects of self-regulation. This paper reports a longitudinal study of 44 children from early to middle childhood. At age 2, the Goodman Lock Box provided information about the extent to which children’s approaches were systematic and planful, as opposed to random, impulsive and disorganised. The same measure was used in a modified form at age 8, and two additional measures of planning and self-control were added: the Porteus Maze Test and the Grocery Shopping Task. At both ages, Lock Box competence was related to planfulness, and there was a significant correlation of Lock Box competence across the two ages. However, the various measures of self-regulation were unrelated. Several measurement issues are highlighted, in particular the difficulties associated with making assumptions about the intent and meaning of children’s task behaviours
