A study of hyperlexia

Twelve children with early intense reading and superior word recognition skills coupled with disordered language and cognitive behavior are described. Cognitive, linguistic, and reading measures evidenced a generalized cognitive deficit in forming superordinate schemata which was not specific to visual or auditory modalities. Positive family histories for reading problems were present for 11 of the 12 children, suggesting a relationship between hyperlexia and dyslexia.     

Making and correcting errors during sentence comprehension: Eye movements in the analysis of structurally ambiguous sentences

Eye movements were recorded as subjects read sentences containing temporary structural ambiguities. In accord with the garden-path theory of sentence comprehension, shorter reading times were found for sentences conforming to certain independently motivated parsing strategies (late closure and minimal attachment) than for comparable sentences which violate these strategies. Further, longer fixation durations were associated with the very first fixation in the region of the sentence which disambiguated the sentence, suggesting that the human sentence-parsing mechanism operates in a rather systematic fashion, immediately computing the structural consequences of fixated material for the analysis of preceding material. The pattern of regressive eye movements did not conform to the view that the parsing mechanism automatically returns to the beginning of the sentence to revise an incorrect analysis of linguistic material nor did it support the view that the parsing mechanism systematically backtracks through the sentence until the source of the erroneous analysis is located. Rather, the pattern of regressions indicated that the parsing mechanism typically engages in selective reanalysis, exploiting whatever information it has available about the type of error it has committed to guide its reanalysis attempts. Finally, it is emphasized that an understanding of the parser's revision procedures is essential to an explanation of why certain linguistic structures cannot be successfully parsed by humans.     

Metalinguistic awareness and language development

Thirty-six 3- and 4-year-old children were given a battery of six metalinguistic tasks and two measures of language development: the Peabody Picture Vocabulary Test and a sentence comprehension test. The results clearly showed that the majority of preschoolers were able to make at least some metalinguistic judgments, and that metalinguistic performance improved with age. Furthermore, overall performance on the metalinguistic tasks was significantly correlated with each language measure when the effects of age were partialed out. In contrast, the correlation between age and metalinguistic performance was not significant once the effects of both language measures were partialed out. These data demonstrate that preschoolers' metalinguistic abilities are more extensive than has been previously acknowledged, and that they are closely tied to other aspects of language development at this time.     

The psychological representation of musical pitch in a tonal context

In this series of experiments, evidence was found for a complex psychological representation of musical pitch. The results of a scaling study, in which subjects judged the similarities between pairs of tones presented in an explicitly tonal context, suggest that musical listeners extract a pattern of relationships among tones that is determined not only by pitch height and chroma, but also by membership in the major triad chord and the diatonic scale associated with the tonal system of the context. Multidimensional scaling of the similarity ratings gave a three-dimensional conical structure around which the tones were ordered according to pitch height. The major triad components formed a closely related cluster near the vertex of the cone; the remaining diatonic scale tones formed a less closely related subset farther from the vertex; and, the nondiatonic tones, still farther from the vertex, were widely dispersed. The results also suggest that, in the psychological representation, tones less closely related to the tonality are less stable than tones closely related to the tonality, and that the representation incorporates the tendency for unstable tones to move toward the more stable tones in time, reflecting the dynamic character of musical tones. In the similarity ratings of the scaling study, tones less related to the tonality were judged more similar to tones more related to the tonality than the reverse temporal order. Furthermore, in a delayed recognition task memory performance for nondiatonic tones was less accurate than for diatonic tones, and nondiatonic tones were more often confused with diatonic tones than diatonic tones were confused with nondiatonic tones. These results indicate the tonality-specific nature of the psychological representation and argue that the perception of music depends not only on psychoacoustic properties of the tones, but also on processes that relate the tones to one another through contact with a well-defined and complex psychological representation of musical pitch.     

The effect of syntactic encoding on sentence comprehension in aphasia.

This study compared two levels of syntactic encoding with respect to their effect on aphasics' auditory comprehension. The same informational content was presented either as an embedded sentence or as two contiguous simplé propositions. A similar contrast was utilized to compare sentences containing relational terms of time, comparison, instrumentality, as well as sentences involving conjunction reduction, with parallel messages expressed in expanded, simplified form. A picture-verification paradigm was used. Comprehension was significantly enhanced only in the case of embedded sentences, with a tendency for Broca's aphasics to show the maximum effects.     

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
