Outcome predictors in the behavioral treatment of stuttering

The MMPI and subscales of the Stuttering Severity scale were utilized to predict motivation and success in the behavioral treatment of 32 stutterers. Subjects spent a mean of 10 individual sessions in criterion-oriented learning of fluent speech based on speech-muscle relaxation aided by EMG visual biofeedback. Judged motivation and judged success were strongly related to each other and significantly related to MMPI K and Es scores and negatively to F and Sc. Actual success was negatively related to Sc and Pd, completely unrelated to Es, and (if anything) negatively related to K. Results are consistent with previous studies, and show that global judgements of progress were only minimally related to a measure of actual progress.     

Bibliography of literature pertaining to the onset,development, and treatment of stuttering during the preschool years

This bibliography consists of clinical, experimental, and theoretical papers pertaining to the onset, development, and treatment of stuttering in children five- years old and younger. It is a downward extension of Silverman, F.H., Bibliography of literature pertaining to stuttering in elementary-school children, Journal of Fluency Disorders, 1978, 3, 87–102.     

Pathological left-handedness: Evaluation of a model

This study investigated the relationship between manifest handedness and the localization of EEG abnormalities in a large group of mentally retarded persons. Persons who had abnormal EEG recordings, regardless of whether the dysfunction was bilateral or asymmetric, exhibited approximately twice the incidence of left-handedness than persons who had normal EEG's. Data for persons having asymmetric damage support a model of pathological left-handedness, with left-handers showing a substantially higher probability of having left brain dysfunction than right-handers.     

Cortical involvement in the semantic processing of coarticulated speech cues

Auditory evoked responses (AER) were recorded from scalp locations over the left and right temporal regions in response to CVC words and nonsense syllables. Various components of the AER were found to vary systematically with changes in stimulus meaning. One such component reflected subcortical involvement in semantic processing. Other components reflected changes in voicing and place of articulation as well as hemisphere differences.     

Auditory processing and anxiety in stutterers

This study utilized the Synthetic Sentence Identification/Ipsilateral and Contralateral Competing Message subtests and the State-Trait Anxiety Inventory to examine auditory processing deficits, anxiety levels, and the interaction of these two components in 15 adult stutterers and 15 nonstutterers. Results support brainstem auditory processing deficits in stutterers and equalization of cortical functioning between groups. Group differences were not found in anxiety levels. Nonsignificant correlations between anxiety levels and auditory processing were revealed.     

Memory scanning,introversion-extraversion,and levels of processing

Individual differences in information processing were studied in the form of the hypothesis that arousal, as indexed by a personality measure of introversion-extraversion, affects the speed with which certain kinds of processing are completed. The Sternberg paradigm was used, and the results suggested that introverts and extraverts scanned for physical features equally rapidly, but that introverts were slower than extraverts at scanning for the semantic features of category membership. There was limited support for the hypothesis that introverts, thought to be more aroused than extraverts, are less able to engage in shared or parallel processing. It was concluded that information processing in introverts and extraverts may differ qualitatively as well as quantitatively.     

Lateralization for reading musical chords: Disentangling symbolic, analytic, and phonological aspects of reading

It has been repeatedly shown that the left hemisphere (right visual field) is superior to the right hemisphere (LVF) in reading English, a bias possibly due to any or all of three confounded factors: (1) the symbolic nature of the coding system; (2) the analytic requirements of the decoding process; and (3) the phonological associations of the elements. Recent work on reading Japanese ideograms (Kanji) disentangles (1) from (2) and (3), but leaves the latter two confounded. We further disentangle (2) and (3) by examining visual field preference for reading musical chords, representatives of an analytic, nonphonological symbol system. The strong RVF advantage is interpreted as indicating that the left hemisphere is dominant for reading an analytic symbol system that is not phonologically based. We conclude that the left-hemisphere advantage traditionally found for reading phonological symbols is due to their analytic nature in addition to any effect due to their linguistic association.     

Hominid evolution, supralaryngeal vocal tract physiology, and the fossil evidence for reconstructions.

The functional, physiologic aspects of the human supralaryngeal vocal tract, which follow from the equal length of the oral and pharyngeal cavities and their right angle orientation are discussed. Sounds like the vowels [i] and [u], which only the human supralaryngeal vocal tract can produce in a Quantal mode, provide a selective advantage for vocal communication and the evolution of the human vocal tract and matched neural property detectors. The dissimilarity between Neanderthal skulls and specimens of anatomically modern Homo sapiens and other fossil skulls is discussed in relation to the reconstruction of the Neanderthal supralaryngeal vocal tract. The absence of some of the innate neural property detectors that play a part in the perception of human speech can be inferred in Neanderthal hominids from the reconstruction of their supralaryngeal vocal tract.     

Menstrual symptom questionnaire: further psychometric evaluation

Novak, Jones, and Jones (1975) state that menstrual distress (dysmenorrhea) is the greatest cause of lost work hours among women, and Kistner (1970) estimate this to be 140 million annual work hours. Thirty-five percent of female adolescents. 25% of college women, and 60–70% of single females in their 30's and 40's are said to be invalid during menstruation (Green, 1971). Treatment procedures for primary dysmenorrhea have included hypnosis (Lackie, 1964), physical exercises (Golub. 1959). natural childbirth techniques (House, 1969), and oral contraceptives.

Though hormones are the most recent, frequent and effective treatment approach (Novak et al. 1975). Tyler (1973) cautions against their use because of possible adverse side effects. Recently, systematic desensitization (SD) has been used to relieve menstrual distress (Mullen, 1968, 1971; Reich, 1972; Tasto and Chesney, 1974) without risk of such side effects. Although SD has been effective, considerable response variability has been noted.

Becuase of this variability. Chesney and Tasto (1975a) developed the Menstrual Symptom Questionnaire (MSQ) to psychometrically identify two types of primary dysmenorrhea: spasdomic dysmenorrhea which designates distress during the flow period associated with excessive muscle tension, and congestive dysmenorrhea referring to premenstrual tension related to water retention. This instrument was designed to define types of menstrual symptoms and not symptom severity. Test-retest reliability was 0.87 and discrimination between spasdomic and congestive dysmenorrhea was highly significant. Of 48 women tested. 29 were identified as spasdomic with MSQ scores between 82 and 102, while 19 scored in the congestive range (46–68). Interestingly, no women scored in the median range (69–81), suggesting that there exists two unique types of primary dysmenorrhea identifiable by the MSQ. Subsequently, Chesney and Tasto (1975b) reported that congestive women did not respond to SD, while spasdomic symptoms were significantly reduced. It was hypothesized that the relaxation training component of SD was effective with spasmodic muscle tension symptoms and ineffective with congestive water retention symptoms. Consequently, the MSQ was thought capable of accounting for previously reported response variability of primary dysmenorrhea to SD.

The present study was intended to replicate Chesney and Tasto's (1975a, 1975b) findings. The following Null hypotheses were tested; (a) the MSQ does not have significant test-retest reliability; (b) the congestive-spasmodic symptom dimension of the MSQ is not dichotomous; and (c) the MSQ does not predict SD effectiveness
