In this study, we examined the eating behavior of four handicapped children, none of whom exhibited self-feeding skills. All children had a history of food refusal and were nutritionally at risk; one child received all nourishment by way of a gastrostomy tube. Baseline data taken during mealtimes indicated that all children accepted very little food, expelled food frequently, and engaged in a number of disruptive behaviors. Treatments consisted of one or more of the following contingent events: social praise, access to preferred foods, brief periods of toy play, and forced feeding. Results of multiple-baseline and reversal designs showed marked behavioral improvement for each child and increases in the amount of food consumed. Further improvements were noted at follow-up, which ranged from 7 to 30 months posttreatment.  相似文献

Ultrasound technology has not been used extensively in the study of normal and abnormal oral physiology and speech. Features such as soft tissue detail, real-time motion display, and subject safety make ultrasound ideal for imaging the tongue and the floor of the mouth. This study demonstrates visualization of the muscles of the tongue and floor of the mouth for a normal subject using ultrasound imaging. By employing submandibular transducer placement of real-time sector scanners, tongue anatomy and motion were continuously visualized in sagittal or coronal planes. In addition to the entire tongue surface, much of the intrinsic anatomy was identified including: the genioglossus, geniohyoid, mylohyoid, and digastric muscles; fascial boundaries such as the median fibrous septum, floor intermuscular septum, and paramedian septums; and the hyoid bone. A tongue excised from a human cadaver was scanned using ultrasound and dissected to confirm the anatomy seen in the live tongue. Tongue surface shape and configuration of the intrinsic tissue structures were observed and compared for the phonemes /k/, /u/, and /i/. Anatomical landmarks in the resting and speaking tongue are discussed as well as applications in the fields of speech science and speech pathology.  相似文献

This investigation attempted to replicate and to clarify methodologically an investigation by Pollak and Gilligan (1982). Those investigators reported sex differences in violence imagery to Thematic Apperception Test (TAT) pictures depicting affiliation and achievement situations. Pollak and Gilligan concluded that men perceive danger in situations of affiliation whereas women perceive danger in situations of achievement. It was demonstrated in the present study that Pollak and Gilligan incorrectly classified TAT cards into motivational categories, which may have resulted in incorrect inferences. In addition, their findings could not be replicated when using four different systems for classifying TAT cards into motivational categories. Other potential sources of error in their research, including a restrictive scoring scheme for hostility, unusual instructions, and failure to control for sex role in the TAT pictures, did not influence the pattern of results.  相似文献

The Rorschach protocols of 43 males consecutively admitted to a university outpatient clinic were scored for frequency of the 20 Wheeler signs of homosexuality. Based on case history data, patients were assigned to homosexual, sex-role disturbed, or normal-control groups. In addition to the traditional group comparison the results were analyzed to yield P (Ci/Rj); that is, the probability of criterion group membership given test indicator. Both the homosexual and sex-role disturbed group displayed significantly more Wheeler signs than normals. Furthermore, given a Wheeler sign score of 15%, .75 of the predicted-homosexual group would be correctly classified compared to a .21 baserate prediction. It was suggested that expressing results as P (Ci/Rj) provides information more relevant to the clinician than is provided by the traditional practice of reporting significant differences between groups.  相似文献

Traditionally counseling has been concerned with client change. The point of view taken here is that the goals and clientele of employment counseling require concern with social change as well as client change.  相似文献
