We examined the interrater and test-retest reliability of the KATZ Adjustment Scale (Relative rated or R form) longitudinally in a sample of schizophrenic patients, assessing their function before hospital admission, as well as at 1 and 9 mo. after discharge. Changes in mean scores over those assessments suggested sensitivity to change while mothers and fathers both completed the measure with moderate consistency over time. Interrater reliability was moderate at best and quite poor at initial testing, when the subjects were most disturbed clinically, suggesting that the scales may be acceptable when the individual is stable but that ratings may be unreliable when there is an exacerbation in clinical state.  相似文献

To study the self-projective representations expressed by diabetic children, aged between 10 and 15 yr., and to compare these with representations of a control group the Draw-a-person test associated with those for subsequent Draw-a-sick-person were administered to 23 children regularly checked by an Antidiabetic Centre. The diabetic subjects drew an image of "sick person" having projective elements with a regressive value and denoting a refuge in the past, together with depressive signs of retiring into themselves and of less consideration of the self. Also, the diabetic children seemed to be less prone to the cultural stereotype which requires a smiling and happy image of "the healthy person." At the same time there was also a transparent symbolic defense which allowed the diabetics to adapt variously and to move from their anxious state toward psychological recovery.  相似文献

Georg Ilberg, who is almost forgotten nowadays, was a scholar of Kraepelin and Ganser. From 1910 to 1928 he was director of the Landes-Heil- und Pflegeanstalt (country mental hospital) for mental patients Sonnenstein at Pirna. He was active in the scientific-literary field to a great age and worked as editor of the Allgemeine Zeitschrift für Psychiatrie from 1924 to 1934. Although he principally advocated the exclusion of certain mental patients from reproduction at the beginning of the 1930s, in a review in 1942, his integer humanist basic position and his pronounced social feeling made him to protest in public against the putting to death of mental in-patients.  相似文献

Cognition and olfaction: a review   总被引:5,自引:0,他引:5  
Examines research in cognitive psychology, which has in the past paid little attention to the olfactory modality. But there is now a significant body of literature on the role of the olfactory system in memory and cognition. Human beings possess an excellent ability to detect and discriminate odors, but they typically have great difficulty in identifying particular odorants. This results partly from the use of an improverished and idiosyncratic language to describe olfactory experiences, which are normally encoded either in a rudimentary sensory form or as part of a complex but highly specific biographical episode. Consequently, linguistic processes play only a very limited role in olfactory processing, whereas hedonic factors seem to be of considerable importance.  相似文献

Ambiguity, which is an intrinsic and essential aspect of the psychoanalytic situation, is related to the concepts of transitional phenomena and projective identification. The analyst's feelings of uncertainty that accompany this ambiguity are contrasted with a "pathological certainty." The consequences of the loss of ambiguity and the role of the analyst's countertransference in this process are described.  相似文献

Test of speech-sound discrimination are used by special educators, reading specialists and speech-language pathologists in assessing children's ability to differentiate between speech sounds occurring in standard English. Such tests are important in determining if speech-sound articulation errors are caused by difficulty in making such differentiations. However, during the past 10 years, these tests have been criticized on the basis of their reliability and validity. The purpose of this study was to examine the use of two alternative methods of assessing speech-sound discrimination with a school-aged population to determine if they elicited responses in a similar manner.  相似文献

The rod-and-frame effect (RFE) was investigated with the use of a frame that oscillated about an axis at its center at five different frequencies, ranging from .013 to .213 Hz. The resultant RFE shifted continuously with the roll motion of the frame, and it was significantly larger at the lowest frequency (.013 Hz) than under comparable static conditions. The dynamic RFE was lowest at the higher oscillation frequencies. Oscillatory roll vection--apparent self-motion--was reported by 3 of the 9 subjects when the frame was oscillating at its highest frequency (.213 Hz). The subjects yielded large increases in the RFE during the sessions with reports of vection. Surrounding the kinetic frame with a circular contour eliminated all reports of vection and significantly interacted with frequency to reduce the RFE--but only at low frequencies. The reduction amounted to 21.2% averaged over all 9 subjects at the three lowest frequencies. A surrounding contour, therefore, suppressed low-frequency kinetic visual orientation information that might otherwise have produced larger changes in apparent self-orientation and perceived vertical. Vection-sensitive subjects differed from nonvection subjects by exhibiting (1) a high-frequency fall-off in real-motion gain, (2) a high-frequency enhancement in illusory-motion gain, and (3) only a small and nonsignificant increase in illusory-movement phase lag with increases in frequency.  相似文献
