We present four cases of Prader-Willi syndrome. Two of them have an abnormality of a chromosome 15, the other both show different chromosomal abnormalities. Translocations or deletions were found recently in the bands 15q11/12 in about 60% of the cases of Prader-Willi syndrome. The consequences for diagnosis, symptomatology and genetic counselling of the syndrome are discussed. 相似文献

For four of six autistic children who underwent intensive behavioral treatment, the nature of their self-stimulatory behavior changed from initial lowlevel motor behaviors (such as rocking, spinning, twirling) to differing kinds of higher-level behaviors (such as lining of objects, echolalic speech, and preoccupation with spelling and numerical values). The children who changed to the highest levels of self-stimulatory behavior also showed the largest gains in treatment (as determined by IQ scores, school placement, etc.). The changes in self-stimulatory behaviors were attributed to the intense teaching of appropriate social behaviors and the explicit therapeutic suppression of low-level, self-stimulatory behaviors. The long-term therapeutic effects of changing from lower-to higher-level forms of self-stimulatory behavior were discussed.This study was supported by a grant from the National Institute of Mental Health (grant MH 11440). We want to express our thanks to the parents who allowed us to study their children. We gratefully acknowledge the assistance of Maria Audero with the design of the weighted measure, and Tracee Parker with the collection of the data. 相似文献

Psychology as both a science and a profession has been closely identified with other disciplines in the broad field of health since the turn of the century. Recent advances in health care have reinforced the growing belief that the promotion of health and the prevention and treatment of illness can be greatly enhanced by incorporating the scientific findings and modern technology of psychology into everyday practices. Outlining the contributions of psychology to health care throughout the world is the primary purpose of this report. In this brief survey, only some of the most timely and relevant issues can be mentioned, together with examples of current work in the field. The reader interested in pursuing these psychological contributions more thoroughly is encouraged to review pertinent references from the citations at the end of this report. After an introductory overview, special attention is given to each of the major areas within the broad field of health care where psychological applications have been particularly useful. 相似文献

Age differences in memory for item and source information 总被引:1,自引:0,他引:1

Some researchers have speculated that left-hand dominance is more prevalent among patients suffering from dementia of the Alzheimer's type which began prior to age 65 yr. and that, in those patients, the disease runs a more rapid course. In the present study, seven left-handed dementia patients were matched with seven right-handed dementia patients on the basis of age and years of education and were compared with regard to neuropsychological compromise. While the left-handed group was somewhat more impaired than the right-handed subjects, the difference between the two groups was not statistically significant. 相似文献

Separate verbal memory and naming deficits in attention deficit disorder and reading disability 总被引:4,自引:0,他引:4
In this study, verbal memory and naming abilities were investigated in reading disabled (RD) and control children who were characterized according to the presence or absence of attention deficit disorder (ADD). Results indicate that deficits in learning and memory for recently acquired information occur as a function of ADD rather than RD while deficits in naming are specific to RD rather than ADD. We conclude that ADD is a major source of additional and separate cognitive morbidity in RD children. 相似文献

This study evaluated the clinical validity of the Intellectual Screening, Development, and Achievement scales of the Personality Inventory for Children-Revised (PIC-R), as well as the newly derived PIC-R Factor IV scale, in identifying cognitive impairment in a clinic-referred sample of preschoolers. The clinical validity of these PIC-R subscales was also compared to that of the Minnesota Child Development Inventory (MCDI). The results showed that the PIC-R scales and Factor IV were reasonably successful in identifying cognitively impaired preschoolers, but much less successful in identifying cognitively normal preschoolers. Overall, the MCDI was the most successful in correctly identifying the preschoolers' cognitive status. 相似文献

Previous research has demonstrated that changes in vocal frequency (pitch) influence judgments made about a speaker, although there is some question as to the relative importance of frequency to message content in person perception. Moreover, these studies have failed to examine the possible joint effect of frequency and individual differences in nonverbal sensitivity on person perception. The purpose of the present investigation was to examine the independent and joint effects of vocal frequency, perceptual salience, and nonverbal sensitivity (assessed by the Profile of Nonverbal Sensitivity) on person perception. Participants were assigned to one of nine experimental conditions and were asked to rate two male and two female speakers on seven unipolar adjective scales. The nine conditions were produced by factorially combining three levels each of salience (content, voice, control) and vocal frequency (decreased, increased, unmanipulated). The results of hierarchical multiple regression analyses indicated that variations in frequency did influence evaluative judgments of the speakers (competent, honest, persuasive), but that the magnitude of the influence varied as a function of the participants' levels of nonverbal sensitivity. The analyses, however, yielded no significant effects for participants' affective judgments, nor any significant effects involving perceptual salience. 相似文献

Animals filled almost to satiation by nonnutritive bulk do not satiate when they ingest a small amount of seaweed. This suggests that satiation is not triggered by chemostimulation of an anteriorly located "hot spot." Inflation of a balloon placed in the gut of the animal results in satiation as reflected in a number of different parameters of feeding behavior. The suppressive effect of a relatively brief inflation is rapidly and fully reversible, although repeated inflation and deflation appeared to produce slowly reversible or irreversible effects. The parameters of the changes in feeding during gut inflation are comparable to those of normal animals that are slowly fed individual pieces of food. The inflation volume needed to satiate the animal is a function of the rate of inflation--more rapid inflations requiring larger volumes. Cutting of the esophageal nerves results in a significant increase in the volume needed to satiate the animals, but nevertheless they eventually cease feeding and generally do not show a burst gut. The evidence indicates that the satiation that eventually occurs in nerve-sectioned animals, at least in part, is due to depression of feeding following very prolonged sensory stimulation. The data suggest that for a rapidly consumed meal, satiation results primarily due to distension-related gut signals conveyed by the esophageal nerves, whereas for very slowly consumed meals, the former factor interacts with a process associated with sensory stimulation, such as receptor adaptation. The current results indicate that balloon distension can serve as a reasonable stimulus in experiments in simplified preparations in which the nervous system can be studied. 相似文献
