Background: Children with learning disabilities are identified by their severe learning problems and their deficient school achievement. On the other hand, children with sub-average school achievement "and" sub-average intellectual development are thought to suffer from a general intellectual delay rather than from specific learning disabilities.…

In a sample of children with significant learning disabilities, it was found that those born in warm months had higher IQ's than those born in cold months. The effects of temperature and humidity upon neonatal cortex development are offered as a possible explanation of the differences noted. (ST)

The effect of 1 or 2 year special class placement on academic achievement and intellectual functioning of 28 learning disabled children (8 to 11 years old) was investigated. The number of years in a self-contained class significantly affected arithmetic achievement. (Author)
