The subjects were 300 fifth grade students in primary school,
and were composed of 100 LD, 100 UA and 100 normal children
respectively. The Scholastic Aptitude Test for Primary School
Student(SAT), The Achievement Test for Fifth Grade Student(
Chinese and Mathematics), The Learning Behavior Checklist, The
New Jong-Hwa Intelligence Scale and The Stanford -Binet
Intelligence Scale: Fifth Edition(in Taiwan) were administered
to obtain relative information. The data obtained were analyzed
by the Pearson product-moment correlation, principal component
analysis, t-test, the discriminant analysis , ANOVA, and
MANOVA. The major findings of this study were as follows: 1.The
prevalence of learning disabilities is 3.15%(3.73% male, 2.52%
female). 2.The method of constructing LDI could be used in the
two individual intelligence scales, and costructed two pieces
of LDI norm tables. The mean LDI is significat difference among
LD, UA and normal group, and no significant difference between
boy and girl LD. 3.Students of LD group showed significantly
lower than students of UA and normal group in verbal ability,
but no significant difference in nonverbal ability. For LD
group, nonverbal ability is significantly higher than verbal
ability, and showed greater intra-individual differences on
scores of all subtests of both individual intelligence scales.
4.The various intelligence variables of both intelligence
scales could distinguish the LD and normal group effectively.
5.Pearson correlation coeficients showed a higher
correspondence between The New Jong-Hwa Intelligence Scale Full-
Scale IQ and The Stanford-Binet Intelligence Scale Composite
score (r=.861) , and the later(M=91.04) higher the former(
M=88.52), but no significant difference.
