[Intelligence in children with cleft lip and palate].

In a group of 174 children with clefts lip and palate the articulation-connected (sprachgebundene) and non-articulation-connected (nicht sprachgebundene) intelligence have been inquired by the HAWIE- and HAWIK-intelligence test. For this group a general average IQ of 106,6 resulted, that means 6,6 IQ points above a normal 100 level found out for this test. There is a significant difference between the verbal and the action-part, the action-part prevailing in nearly all IQ fields. With due restraint the qualitative interpretation of the subtests discovers a surprising high ability in respect of the verbal forming of conception, the verbal knowledge and the ability to adapt to social norms.
