Abstract
The study investigated the association between physical and
cogni ti ve development during early and middle childhood .
Multistage sampling technique was followed in the selection
of participants . As part of mul ti stage sampling, using
simple random sampling, 60 children between the ages of 4
to 6 years and 60 children between the ages of 7 to 9 years
were selected from the two preschools and two primary
schools respectively . Children's height, head
circumference, and mid-upper-arm circumference were
measured in cm and weight in kilogram. Then cognitive
questionnaire was administered for each child. The resul t
showed that there is positive and statistically significant
relationship between physical and cognitive development .
The resul t also s howed tha t the predicti ve validi ty of
physical development on cogni tive development is
significant for the preoperational group but not for
concrete opera tional group. When across chronological age
is considered , the predicti ve validi ty of physical
development on cognitive development was found to be
statistically significant for children of 4 and 5 years but
not for children of 6 to 9 years. The finding al so showed
the existence of statistically significant difference in
the predicti ve validi ty of physical development on
cognitive development across sexes particularly between
male medium and female medium, and male high and female
high groups, but not between male low and female low
groups .
