The results supported the hypothesis that mentally handicapped children have a significant attraction to symmetrical arrangement, and that Down's syndrome children are more significantly attracted than other retarded children. (Author/DLS)

It was found that five Ss showed the usual higher rate of stuttering on consonants, while one showed more stuttering on vowels; and that a markedly higher rate was found on initial words of sentences in two Ss, both of whom were also exceptional in several other aspects of stuttering. (Author/DLS)

There was a significant decrease in the difference between observed and expected probabilities over the first 30 words following a stutter. Also, the two adult Ss initially increased their stuttering rate. Findings supported a combination of the anxiety and feedback models of A. W. Still and C. A. Sherrard. (Author/DLS)

Among the findings were that there was no significant difference in performance between Down's syndrome, other mentally handicapped, and normal Ss matched for mental age, when extraneous developmental factors were eliminated; and that there was no relationship between mental age and visual perception in any group.

Tape recorded instructions combined with concrete materials were used to teach basic mathematics and shape concepts to a total of 42 mentally handicapped slow learners (8-to 15-years-old) in a 3 special British schools. (LH)

Compared was the performance of 30 nonhandicapped controls and 30 partially sighted British children (6-to 10-years-old) without other handicaps on tests of shape and letter recognition, visual perception and visuomotor skill, and spelling or reading accuracy or comprehension. (LH)

Studied a rare condition, elective mutism in children. Results indicated (1) immature development, especially in speech; (2) high rates of behavior problems; (3) excessive shyness; (4) significantly greater incidence of lower range performance IQ; (5) family psychiatric problems; and (6) intractibility. (Author/DB)

The findings showed that the stimulated group scored higher on both the intelligence and the developmental tests, particularly on personal-social and speech development. In addition, school placement at the age of five years suggested that the experimental Ss were more easily integrated into the normal community. (Author/DLS)
