Influences of rate, length, and complexity on speech disfluency in a single-speech sample in preschool children who stutter

The purpose of the present study was (1) to determine whether speech rate, utterance length, and grammatical complexity (number of clauses and clausal constituents per utterance) influenced stuttering-like disfluencies as children became more disfluent at the end of a 1200-syllable speech sample [Sawyer, J., & Yairi, E. (2006). The effect of sample size on the assessment of stuttering severity. American Journal of Speech-Language Pathology, 15, 36-44] and (2) to explore the interaction of speech rate, length, and grammatical complexity at the beginning (syllables 1-300, Section A) and the end (syllables 901-1200, Section B) of the speech sample. Participants were eight boys and six girls (M=40.9 months) who were selected from the Sawyer and Yairi [Sawyer, J., & Yairi, E. (2006). The effect of sample size on the assessment of stuttering severity. American Journal of Speech-Language Pathology, 15, 36-44] study. Mean length of utterance (MLU) in morphemes, the number of clauses, clausal constituents, and articulation rate, measured in syllables per second were analyzed from the children's conversational speech. The median split procedure [Logan, K., & Conture, E. (1995). Length, grammatical complexity, and rate differences in stuttered and fluent conversational utterances of children who stutter. Journal of Fluency Disorders, 20, 35-61; Yaruss, J. S. (1997). Utterance timing and childhood stuttering. Journal of Fluency Disorders, 22, 263-286] was used to study interactions between articulation rate, utterance length, and grammatical complexity across the two sections. The mean number of clauses per utterance, clausal constituents per utterance, and articulation rate revealed no significant differences between Section A and Section B, whereas MLU significantly increased in Section B (p=.013). Clausal constituents and MLU were significantly correlated both in Sections A and B. The median split procedure revealed trends for utterances characterized as high length and low-speech rate to be greater in number in Section B than A, but the differences were not significant. EDUCATIONAL OBJECTIVES: The reader will learn about and be able to: (a) describe the influence of grammatical complexity and mean length of utterance on disfluent speech; (b) compare different procedures for assessing speech rate and determine why the effects of articulation rate have been inconclusive; (c) discuss procedures for comparing length, rate, and complexity across a single-speech sample; and (d) explain why therapeutic methods that emphasize shorter utterance lengths, rather than only slower speech rates, are advisable in establishing fluency in preschool children who stutter.     

ON THE PRAGMATICS OF SOCIAL THEORY: THE CASE OF ELIAS'S “ON THE PROCESS OF CIVILIZATION”

This paper proposes a new approach to the study of sociological classics. This approach is pragmatic in character. It draws upon the social pragmatism of G. H. Mead and the sociology of texts of D. F. McKenzie. Our object of study is Norbert Elias's On the Process of Civilization. The pragmatic genealogy of this book reveals the importance of taking materiality seriously. By documenting the successive entanglements between human agency and nonhuman factors, we discuss the origins of the book in the 1930s, how it was forgotten for 30 years, and how in the mid‐1970s it became a sociological classic. We explain canonization as a matter of fusion between book's material form and its content, in the context of the paperback revolution of the 1960s, the events of May 1968, and the demise of Parsons’ structural functionalism, and how this provided Elias with an opportunity to advance his model of sociology.     

Chronic Callers to a Suicide Prevention Center

ABSTRACT: Records of 67 chronic callers to the Cleveland Suicide Prevention Centers over the past 9 years are reviewed. Of this group, 51% were diagnosed as drug or alcohol dependent. It was also noted that 4 of the 67 were known to have committed suicide and that another 37 (55%) had made suicide attempts. A surprising finding was that 47% of the group was eventually referred to an ongoing treatment resource. Agency strategies for dealing with the chronic caller are discussed.     

Verbal discrimination reversal in a whole/part re-pairing transfer paradigm

Whole/part transfer and re-pairing of rights and wrongs were employed in a study of verbal discrimination reversal learning. The whole/part and re-pairing procedures were used to create reversal conditions (0%, 50%, or 100% reversal) that were similar at the outset of reversal learning in that all correct alternatives on the reversal list were higher in situational frequency than their respective incorrect alternatives. Similarly, reversal lists were constructed that were similar in that all incorrect alternatives on the reversal list were higher in situational frequency than their respective correct alternatives. The results were consistent with the existing literature on verbal discrimination reversal, as performance was impaired when items reversed functions (50% and 100% reversal). There was little evidence that uniform frequency relations between rights and wrongs affected ease of reversal learning.
