Clustering of disfluency in nonstuttering childrens' early utterances

The clustering of disfluency within early utterances in the speech of four nonstuttering children was examined. During the developmental period their mean length of utterance was between 2.25 and 3.0 morphemes. The frequency and characteristics of the clustered disfluencies are described and compared with single disfluent moments. Clusters of two disfluencies were analyzed for interactive effects of positional preference and type. Results were similar to those found in older preschool nonstuttering speakers, demonstrating the normal developmental nature of clustering in early sentences. Implications for using this temporal measure to differentially diagnose normal from abnormal disfluency are discussed.     

THE EFFECT OF INFORMATIONAL FEEDBACK ON FOOD INTAKE OF ADULT BURN PATIENTS

The effect of informational feedback on the protein and caloric consumption of burn patients was investigated using a multiple-baseline across subjects. The patients were four severely burned adult males who failed to consume sufficient foods to achieve prescribed levels of protein or kilocalories via standard burn unit procedures during recovery. Feedback consisted of informing patients of (a) their prescribed levels of protein and kilocalories, (b) the protein and kilocalorie content of hospital foods and beverages, and (c) their actual intake of protein and kilocalories. Following the provision of feedback, there was an increase in protein and kilocalorie intakes and in the number of days during which prescribed levels for protein and kilocalories were achieved. These results suggest that the informational feedback was effective for improving the oral caloric intake of burn patients.     

The Superwoman ideal and other risk factors for eating disturbances in adolescent girls

The purpose of this study was to investigate the relationship between disordered eating, the Superwoman ideal, competitiveness, and achievement motivation. The EAT-26, Personality Research Form (Achievement scale), and Self-Roles Inventory were administered to 69 10–12th-grade girls (69.6% White, 11.6% Hispanic, 5.8% Black, 5.8% Asian, 7.2% no information on ethnicity). EAT-26 scores were not significantly associated with attending an academically competitive high school, having a high achievement motivation, or considering a number of roles as important to one's sense of self (adherence to the Superwoman ideal). EAT-26 scores were significantly higher among the girls attending the average high school. It is important to conduct further investigations of the Superwoman ideal since it has been posited as a risk factor for eating disorders, but has been the focus of only a few empirical studies.     

The World-Wide Web as a medium for psychoacoustical demonstrations and experiments: Experience and results

The World-Wide Web provides an inviting opportunity to reach large numbers of people, both as an audience for psychoacoustical discussions and demonstrations and as subjects for psychoacoustical experiments. Such use of the Web poses a unique set of challenges. We present the methodologies used to prepare a multimedia primer in auditory perception at McGill University. As well as instructional material, this primer includes acoustical experiments conducted over the Web. We discuss the response and experiences with this site in general and in a particular class situation at Hanover College.     

Acquisition of probabilities in anticipatory appraisals of stress

Processes involved in predicting stressor events were examined from the perspective of ‘associative memory models’. Subjects were exposed to alphabetic letters which supposedly represented electrical resistors used in audio equipment, in the guise of marketing research. Each letter presentation was followed either by a burst of aversive white noise, signifying ‘resistor failure’ during a brief surge of current, or by a green light, signifying ‘resistor effectiveness’. After a programmed series of presentations, subjects were asked to make several judgments about each resistor; analyses of these judgments focused on the comparative influence exerted by the alternate stimulus events. Regardless of the type of judgment (e.g. probability of future noise, frequency of earlier silent outcomes, and so on), the determining stimulus property was the cumulative frequency of earlier aversive outcomes. Moreover, the dominance of this property was not altered by manipulations designed to elevate the salience of equally relevant benign outcomes. Results were discussed with reference to models of categorical memory and predictive confidence. Circumstances under which stress predictions may be especially inaccurate were considered, as were implications of the present findings for studies of differences in categorical-frequency memory processes associated with ‘depresed mood’.     

From prespeech to language: The influence of caregiver-child interaction

Communication is considered a function based on reciprocity and communicativeness with a human partner, the child's participation and capacity, and the adult's adaptiveness and interpreting enable differentiation of messages and meanings. Major precursors of pre-speech communication acts of infants, as suggested by Bruner, are presented, taking into consideration caregiver's mode of interpreting the infant's communication intent, joint referential devices, and strategies for enlisting in joint activity.     

Introduction to the Special Section on Cognitive Science and Psychological Assessment

This introduction to the Special Section on Cognitive Science and Psychological Assessment begins with a brief overview of cognitive science and its interface with the clinical assessment of cognitive functioning. Concepts and themes permeating the articles in this section are then taken up. Included are cognitive-model architectures and model parameters, differential emphasis on efficiency versus content of cognition, and implementation of stochastic and dynamical aspects of cognitive processes. Selected distinguishing attributes of the respective contributions are highlighted.     

Project Trust: breaking down barriers between middle school children

This paper analyzes the success of a camp retreat weekend called Project Trust involving middle school students and teachers. The goal of the camp is to break down barriers between cliques identified as active in the school. The camp focuses on building team relationships across clique membership and incorporates elements of peace education and conflict resolution. A treatment group (campers) and comparison group (noncampers) were administered an adaptation of the Bogardus Social Distance Test and the Piers-Harris Children's Self-Concept Scale before and after the camp. Attendance was found to lower social distance scores for nine of the ten groups/cliques. Campers also had higher self-concept scores after the retreat.
