ABSTRACT
The purpose of this study was to examine how much home environment stimuli and child development at
three years might predict intelligence development in middle childhood. Among four sub-domains in home
environment stimuli and six sub-domains in child development, this study explored which domain may
predict verbal intelligence and performance intelligence quotients. One hundred and forty-three mother-child
dyads participated in this study. When children were at the age of three, the home environment was
assessed with the HOME scale, and child development was measured through the mother’s report and
interview using the K-CDI. Four years later, children's verbal and performance intelligent quotients were
measured with K-WISC-III. Correlational analysis was performed in order to examine the relationship
between home environment stimulus and developmental domain at three years, and verbal intelligence and
performance intelligence at seven years. Furthermore, hierarchical regression analyses was performed in order
to analyze how much the home environment at four years and six developmental domains may predict
verbal and performance intelligence. According to the results of the study, verbal stimulation, fine motor
development, language development and letter and number development were positively correlated with
both verbal and performance intelligence. Among developmental domains, language development predicted
the verbal intelligence quotient, and fine motor development predicted performance intelligence the most.
For home environment stimuli, verbal stimulation somewhat predicted verbal and performance intelligence.
