78 children from three age levels ( M ages 5.7, 7.5, and 9.0 yr.) and from Dutch and nonDutch parents were presented three tasks to index their abilities to construct and reconstruct sequences of social events. The results show that all tasks form a stochastic Guttman-scale indicating that all measures tap the same cognitive ability. The resulting hierarchy of the tasks suggests that the ability to complete an event sequence by selecting from two additional events, i.e., the initial and the final events, preceded ability to select from two alternative events either the correct final or the correct initial event. The latter two constructional abilities preceded ability to reconstruct sequences of social events involving memorizing the sequence and anticipatory and reversibility competences.
