A survey of communicative disorders students' attitudes toward stuttering

Cooper's (1975) Clinician Attitudes Toward Stuttering (CATS) inventories were conpleted by 1,902 speech-language pathology and audiology students from 33 universities, each in a different state. The majority of respondents perceived stutterers as having psychosocial problems and believed that client and parental counseling were essential aspects of treatment. These views were relatively unaffected by student training and clinical exposure. In addition, most of the assumptions of Johnson's diagnosogenic theory of stuttering were held by the majority of the students surveyed. Most of the respondents believed that stuttering was difficult to modify and that speech clinicians were neither adept nor comfortable treating stutterers. These latter attitudes were significantly affected by training, i.e., the more advanced the students' training, the more pessimistic their views on clinician competence. Other professional attitudes and the effect of training on them are also discussed.     

Issues to consider in the differential diagnosis of normal childhood nonfluencies and stuttering

Historically more attention has been focused on the adult stutterer than on the young stutterer. This article discusses three key issues in the differential diagnosis of normal childhood nonfluencies and childhood stuttering. The three issues are (1) whether early childhood disfluencies are heterogeneous or homogeneous phenomena, (2) whether the relationship between normal childhood nonfluencies and early stuttering is continuous or dichotomous, and (3) whether normal nonfluencies and stuttering differ quantitatively or qualitatively. Theoretical research as well as clinical implications of these issues are discussed.     

Speech timing skills of normally fluent and stuttering children and adults

This study was designed to explore the speech timing skills of normally fluent and stuttering children and adults producing two sentences, ten consecutive times at basal and modified speaking rates. Spectrographic displays of subjects' utterances in both conditions were made in order to obtain consonant, vowel, pause, and utterance duration measures. Results showed that (1) the two groups of children produced speech durational values similar to those of the two adult groups and (3) there were no consistent between- and within-group differences in the basal and modified rate conditions. Findings are discussed in terms of methodological and sampling differences that exist between the present study and past research on stutterers' speech production abilities.     

Stress management for teachers: A cognitive-behavioral program

Urban secondary school teachers participated in a cognitive-behavioral stress management program. Assessment data were also collected from a waiting list control group. Dependent measures included self-reported anxiety and stress, and observations of teacher classroom behavior. Results showed that the training program significantly decreased self-reported stress and anxiety. Follow-up data indicated further decrease six weeks after termination of the training program. Results also indicated decreases in motoric manifestations of anxiety in the classroom as a result of the training.     

Effects of initial limb position on the accuracy, reaction time and electromyographic patterns of rapid movements

An experiment was performed to determine the effects of initial limb condition on final accuracy of rapid, elbow flexion movements in the horizontal plane. Electromyographic (EMG) recordings were also taken from an agonist (biceps) and antagonist (triceps) muscle by means of bipolar surface electrodes. In the experiment the subject's forearm was passively oscillated by means of an electric motor, and when an auditory buzzer sounded, the subject was required to react as quickly as possible and rapidly move to the previously learned target angle. Thus, movements could be initiated from either static or moving starting positions. The results indicated that general accuracy was not greatly affected by these manipulations, however, constant error and pre-motor reaction time suggested that subjects may have been utilizing initial limb condition information contrary to a mass-spring view. EMG data showed that the timing characteristics of the agonist and antagonist muscles were modulated, depending on the type of movement produced, supporting an impulse-timing model (Wallace 1981).     

Children's understanding of food and its functions: A preliminary study of the development of concepts of nutrition

Children's developing conceptions of how the body functions nutritionally were examined. Two different tasks provided converging findings. One task asked children to judge the causes of certain end states (e.g., why X is fat). The second task asked children to judge the result of certain contrasting diets (e.g., twin-1 eats twice as much candy as twin-2). The results evidenced; (a) systematic misconceptions on the part of kindergarteners that were overcome by sixth grade; and (b) other fairly sophisticated conceptions present even at the youngest ages tested. The research provides a needed first step toward describing the naive theories of nutrition possessed by children at different ages. Knowledge of childrens' theories of nutrition are essential for optimal planning of curricula and methods in nutrition education.     

Effects of listener feedback on the messages of kindergarten children in a referential communication task

A referential communication paradigm was employed with kindergarten children to determine the effects of systematically varied feedback following inadequate message production. Feedback conditions included three levels of verbal specificity presented either alone or in combination with visual feedback. Results indicated that kindergarten children formulated more adequate referential messages when provided with either highly specific verbal feedback or a chance to view the listener's incorrect choice of referent. The differential effectiveness of various types of feedback was discussed in terms of the role of comparison activities in the referential communication process, and implications for the communicative competency of kindergarten children were considered.     

Visual attention at three months as a predictor of cognitive functioning at two years of age

The purpose of the present study was to examine the predictive power of various cognitive skills at 3 months of age in terms of later cognitive functioning. Habituating to redundant and recovering to novel stimuli at 3 months of age were found to predict later intellectual functioning at 24 months better than 3-month global intelligence or object permanence scores. In terms of information processing skills, recovery predicted later intelligence test scores better than habituation. It is suggested that changes in cognitive functioning may be viewed as a transformation of skills from one age to another rather than as a continuum of the same skills. With regard to the cognitive abilities of the 3-month-old, it is suggested that information processing may be central to cognitive functioning at this age.     

Reaction time,evoked brain potentials,and psychometric g in the severely retarded

Measurements derived from reaction time (RT), movement time (MT), and an index of neural adaptability (NA) derived from averaged evoked potentials are significantly related to each other as well as to g factor scores extracted from a battery of 15 psychometric tests in a sample of 54 severely retarded adults. The RT-MT and NA variables show a shrunken multiple R of .64 (p < .001) with psychometric g.
