[Children with mental retardation after special education].

44 children with mental retardation were tested 4 times with Hiskey-Nebraska test of learning aptitude (H-NTLA) and tested 2 times with personal and social self-sufficiency scales in a special education school in Taiyuan from 1989 to 1992. No significant difference of total IQ was found. The visual association, concept relationship, visual concentration and perceptual abilities were decreased consistently. The rising of IQ was positively associated with mother's higher education, child's higher IQ, mother's professional and technical occupation and child's younger age in beginning special education. The adaptive behavior was rising significantly.
