“…Other cases reported in literature so far, are also predominantly males (Helm et al, 1978;Quinn and Andrews, 1977;Rosenbek et al, 1978). This is in keeping with the well known higher incidence of developmental stuttering in males (Daniels, 1940;Boberg and Shea, 1978;Porfert and Rosenfield, 1978) and calls attention to sex-linked interhemispheric neuropsychological differences. Thus, it could be supposed that females are less affected by acquired stuttering because of their tendency to incomplete dominance (Lake and Bryden, 1976;Ray et al, 1976), which could facilitate compensation of an acquired impairment of language functions.…”

Summary Acquired stuttering in adults was studied in sixteen cases. All were males, except one. In all cases, stuttering occurred following cerebral traumatic or vascular lesions which involved the left hemisphere, bilateral involvement being presumed in traumatic cases. In the majority of cases, stuttering was associated with aphasia, but in some cases it appeared clinically isolated. No significant association with speech apraxia, anomia or with signs of incomplete right handedness, was found. In some cases, acquired stuttering appeared as a severe worsening of pre‐existent developmental stuttering. These findings are compared with previous reports, and controversial points as well as the need for further investigation, are emphasized.

“…Many (Orton, 1928;Travis and Knott, 1937;Jones, 1966) contend that stutterers have bilateral cerebral speech representation underlying their stutter. However, were this true, there should be an increased prevalence of stuttering among left handed individuals; it seems there is not (Daniels, 1940). All categories of stutterers had a positive family history of stuttering.…”

“…The prevalence of stuttering in an adult population has been estimated at 1%; in childhood it is approximately 4%. The relationship between stuttering and handedness, shift of handedness, and inheritance is unresolved (Daniels, 1940;Heltman, 1940;Johnson, 1955;Sheehan, 1970). The prevalence of stuttering in our adult population was 2.1%.…”

“…These topics have not been evaluated recently (Sheehan and Martin, 1966). Many evaluations of the prevalence of stuttering were by speech clinicians who examined individuals briefly and often missed mild stutterers (Daniels, 1940).

SUMMARY The prevalence of stuttering in a university population was 2.1%; 3.4%/0 were former stutterers. More men than women stuttered. Right handed female stutterers were less likely to have "lost" their stutter than were right handed males. Stutterers, past stutterers, and questionable stutterers all had a family history of stuttering. The significant prevalence of stuttering, the increased prevalence among males, the lack of a decline of this disorder over the past few decades despite the increased number of speech clinicians and data concerning handedness, emphasise the need to investigate organic causes of stuttering.The aetiology of stuttering is unresolved. Many contend that the various speech therapies used in recent years have decreased the number of stutterers. We investigated the prevalence of stuttering in an adult population, and examined the correlation with handedness, sex, and family history. These topics have not been evaluated recently (Sheehan and Martin, 1966). Many evaluations of the prevalence of stuttering were by speech clinicians who examined individuals briefly and often missed mild stutterers (Daniels, 1940). Questionnaires frequently asked whether or not individuals "ever stuttered when they talked," a question yielding a false higher yield than asking whether or not the individual "is or has been a stutterer" (Bloodstein, 1969 Accepted 29 May 1978 The survey was conducted at the University of Massachusetts (Amherst Campus). Students were approached while waiting in queues for various administrative purposes. They were asked about their sex, age, highest grade completed, family history of stuttering, and whether they were or had been stutterers. They were also asked about handedness-right, left, or mixed-and whether they had been forced to change handedness. Questions concerning handedness were intentionally simple to keep the questionnaire brief enough to encourage co-operation.Subjects were divided into four categoriesstutterers, past stutterers, non-stutterers, and questionable stutterers. The latter group was added after the survey, to indicate individuals who stuttered occasionally or under specific circumstances (for example, fatigue, alcohol, marijuana smoking). Because of the small numbers of subjects in the stuttering categories, we combined left and mixed handedness under the category of non-right handedness. ResultsForty-four subjects (2.1%) were stutterers, 71 (3.4%) were former stutterers, and 27 (1.3%) were questionable stutterers (see above).The interaction between sex and stuttering (Table l) was significant (x2=16.9, P<0.001,df3). In the stutterer and past stutterer categories, there were more men than women than would be expected if sex were independent. This effect was determined by a significant interaction of handedness, sex, and stuttering categories (x2= 21.8, P<0.01,df9). The distribution of non-right handed 954

The phenomenon of left-handedness is reviewed from prehistoric man through contemporary studies of lateralization of cerebral function. The following conclusions seem warranted: Handedness is most appropriately regarded as a continuum ranging from strong right-handedness across mixed-handedness to strong left-handedness. Left-handedness, ranging from moderate through strongly lefthanded, is found in approximately 10% of the population. Evidence for a genetic basis of handedness remains positive, but with no direct link established. There is remarkably little evidence for any association of left-handedness with deficit, as has often been suggested. The familial left-handed show greater recovery of functioning following unilateral cerebral insult than do nonfamilial right-handed and nonfamilial left-handed. Both behavioral and clinical lesion studies indicate systematic differences in lateralization of cerebral function between the right-and left-handed and the familial and nonfamilial left-handed. A classification of handedness and lateralization of cerebral function is suggested, with the right-handed with no family history of left-handedness being the most strongly lateralized and the left-handed with a positive family history of left-handedness showing bilateral localization of functions. The left-handed with no family history of left-handedness are classified as identical in cerebral lateralization with the right-handed with no family history of left-handedness. The possibilities exist that bilaterality of cerebral functioning is either stable in the human race or is changing at an extremely slow rate.In the Old Testament, in the Book of Lord's left hand, what part, if any, it played Psalms (Joint Committee on the New Trans-in the creation of the heavens, and who is lation of the Bible, 1970), the statement is held in the left hand. However, in the New made that the Lord's "right hand is full of Testament, the Book of Matthew (Joint righteousness" (48:10); in the Book of Isaiah, Committee, 1970) provides some fairly specific that his "right hand shall spread out the information on the fate of those individuals heavens" (48:13); and again in Psalms, that at the left hand: his "right hand shall hold me" (139:10). c . ,. , , "",, /-\u rn i i.-j -c.
