Seventy-one families from a low socio-economic background, each with a
son at risk of developing psychosocial problems at the onset of the s
tudy, were observed three times over a six-year period while solving a
combinatorial task presented on a microcomputer. The permutations tas
k was used to gather information with regard to cognitive functioning
and cognitive self-regulation of the families, which were observed as
a developmental unit. Cognitive functioning was assessed according to
three variables: cognitive strategies, performance, and completion of
the task. Six self-regulatory activities were assessed: task definitio
n, planning, supervision, evaluation, parental support, and sharing of
responsibilities. Although inefficient strategies were mainly used ac
ross the six years, the cognitive level of functioning improved over t
he years. Cognitive self-regulatory activities most often used across
time were supervision and parental support. Differences were observed
in the three time periods for supervision, task definition, parental s
upport, and individual involvement. Results indicated a link between c
ognitive strategies used by the families to solve the task and their s
elf-regulatory activities. Results are interpreted within both the Pia
getian and Vygotskian perspectives. Families' cognitive self-regulator
y activities observed in this study are an example of parental disenga
gement and children's growing involvement in a joint activity.
