Enuresis was investigated in the context of different styles of training for bladder control among three Israeli ethnic groups (Jews of Moroccan, Kurdish or Eastern European descent). Semistructured interviews were conducted in ethnically homogeneous agricultural villages with 46 mothers of 248 children between the ages of 3 and 18 years. In contrast to previous British and American studies, no sex differences were found, but there were higher rates of primary enuresis and lower rates of secondary (regressive) enuresis. Enuresis was correlated among siblings in the Kurdish group only and with disorderly sleeping arrangements in the Moroccan group. The Moroccan and Kurdish groups had higher rates of enuresis than the Ashkenazi group. The higher rates appear to be related to differences in the age of onset of training and a lack of age-appropriate changes in the parent-child interaction, which led to chronic enuresis and the inability to seek effective assistance. These results are discussed in terms of a proposed typology for training: an early symbiotic style, a strict toddler style, and a communicative partnership. 相似文献

Two experiments compared placebo and hypnotic analgesia in high and low hypnotizable subjects. Experiment 1 demonstrated that hypnotic and placebo analgesia were equally ineffective in low hypnotizables, but that hypnotic analgesia was much more effective than placebo analgesia in high hypnotizables. Experiment 2 replicated these results, but also included low and high hypnotizables who were given a nonhypnotic suggestion for analgesia. Both the low and high hypnotizables in this group reported greater suggested than placebo analgesia and as much suggested analgesia as high hypnotizable hypnotic subjects. Both experiments found substantial discrepancies between the amount of pain reduction subjects expected from the various treatments and the amount of pain reduction they actually reported following exposure to those treatments. In Experiment 2, subjects in all treatments who reduced reported pain engaged in more cognitive coping and less catastrophizing than those who did not reduce pain. Theoretical implications are discussed. 相似文献

ABSTRACT Lamiell's (1981) “idiothetic” index has been praised for raising significant conceptual and methodological issues, but Paunonen and Jackson (1986a) indicated that it might not provide any unique information The current study demonstrates that the unique value of the idiothetic index relative to the ipsative, normative, and normative-ipsative indices is dependent in part upon what information is collected and how it is analyzed Subjects completed inventories on three occasions that assessed seven dispositional variables Interindividual analyses indicated a high correlation between the idiothetic method and two of the other models, whereas intra-individual analyses indicated a much lower degree of correlation Intra-individual analyses indicated that the idiothetic method produced higher temporal stability coefficients The idiothetic index provides information not contained in a normative index and it may be more useful to personality researchers for the assessment of temporal stability and for the assessment of traits with extreme base rates 相似文献

Twenty-eight boys and 28 girls at each of the Piagetian preoperational, concrete operational, and formal operational cognitive stages were given an interview focusing on their concepts of family. Half of each group were from intact families, and half were from divorced families. Interviews were scored for two structural aspects of the concept of family: conceptual level, and use of dimensions that structure the concept. The complexity of children's concepts was strongly related to cognitive stage and, to a lesser degree, to sex. Frequency of use of concept dimensions was strongly affected by general developmental level, though not specifically cognitive stage, and by intactness of family, but to a lesser degree by sex. Specific information is provided on the effect of these factors on perceptions of family composition, parental roles, and breadth of family activities. 相似文献

We assessed the effects of video modeling on acquisition and generalization of conversational skills among autistic children. Three autistic boys observed videotaped conversations consisting of two people discussing specific toys. When criterion for learning was met, generalization of conversational skills was assessed with untrained topics of conversation; new stimuli (toys); unfamiliar persons, siblings, and autistic peers; and other settings. The results indicated that the children learned through video modeling, generalized their conversational skills, and maintained conversational speech over a 15-month period. Video modeling shows much promise as a rapid and effective procedure for teaching complex verbal skills such as conversational speech. 相似文献

There is increased evidence that infants who receive poor quality social stimulation from their primary caregiver are at risk for later developmental difficulties. This paper describes a preventive intervention for mother-infant dyads exhibiting impaired patterns of social interaction. An impaired relationship with the primary caregiver has been found to be associated with social and emotional deficits in early childhood as well as with significant psychopathology in adulthood. The intervention consisted of group treatment of mothers and their infants. Each group session has 4 subsections which, together, were directed towards improving the mothers' ability to relate in a stimulating and nurturant manner to their children. Types of intervention included didactic instruction, modeling, and interpretation of the infant's behavior. Qualitative data suggested that the group intervention has positive effects on the mother-infant dyads. 相似文献

This study examined how elderly residents' adaptation is affected by naturally occurring levels of choice and control in sheltered care facilities. A representative sample of 244 residential care facilities was assessed with the Multiphasic Environmental Assessment Procedure, which measures the quality of residential settings for older people. Overall, facility policies allowing more choice and control were associated with better rated resident well-being, less use of health, daily living assistance, and social-recreational services, and more integration in the community. Policy clarity and the facility social climate factors of independence, influence, and organization mediated the relationship between choice and control and adaptation, and also independently affected residents' adaptation. In addition, in facilities with functionally able residents, more choice and independence were associated with less use of services; in facilities with residents of poor functional ability, choice and independence were unrelated to use of services. Thus, policies that promote more choice and independence may improve adaptation among functionally able residents of sheltered care facilities, without having a detrimental influence on poorly functioning residents. 相似文献

Helmholtz and Zoellner: nineteenth-century empiricism, spiritism, and the theory of space perception
W H Stromberg 《Journal of the history of the behavioral sciences》1989,25(4):371-383
J. K. F. Zoellner began writing on "experimental proofs" of a fourth spatial dimension, and of the existence of spirits, in 1878. His arguments caused strong controversy, with rebuttal essays by Wilhelm Wundt and others. The author argues that Zoellner's case that these matters are experimental questions rested on arguments which Hermann von Helmholtz, inveighing against rationalist views of space and space perception, had recently published. Zoellner's use of Helmholtz's arguments to advance and defend his spiritist views occasioned strong criticism of Helmholtz, affected careers and reputations of scholars in Berlin and Leipzig, and caused enduring controversy over the credibility of Helmholtz's empiricist theory of space perception. 相似文献
