In this paper I argue against the commonly received view that Kripke’s formal Possible World Semantics (PWS) reflects the adoption of a metaphysical interpretation of the modal operators. I consider in detail Kripke’s three main innovations vis-à-vis Carnap’s PWS: a new view of the worlds, variable domains of quantification, and the adoption of a notion of universal validity. I argue that all these changes are driven by the natural technical development of the model theory and its related notion of validity: they are dictated by merely formal considerations, not interpretive concerns. I conclude that Kripke’s model theoretic semantics does not induce a metaphysical reading of necessity, and is formally adequate independently of the specific interpretation of the modal operators. 相似文献

The aim of this study was to examine dimensions of body-esteem, Body Mass Index, and their relations with eating disorder symptoms among 42 elite adolescent athletes engaged in competitive synchronized swimming (M = 15.4 yr., SD = 1.2) and to compare them with 40 athletes in sports with no emphasis on leanness (M = 16.5 yr., SD = .93), and 50 nonathlete college female students (M = 16.3 yr., SD = 1.1). They completed the Body-esteem Scale and the Eating Attitudes Test, and the Body Mass Index was computed. Analysis showed synchronized swimmers reported greater negative feelings about their appearance than the two other groups and low perceptions of how others evaluate their physical appearance. Participants did not differ on the EAT-26. Regression analyses showed that Body Mass Index and Body-esteem Appearance accounted for 38% of the variance in log-transformed Dieting scores of synchronized swimmers. Results are discussed in relation to the literature. 相似文献

Despite the constantly varying stream of sensory information that surrounds us, we humans can discern the small building blocks of words that constitute language (phonetic forms) and perceive them categorically (categorical perception, CP). Decades of controversy have prevailed regarding what is at the heart of CP, with many arguing that it is due to domain-general perceptual processing and others that it is determined by the existence of domain-specific linguistic processing. What is most key: perceptual or linguistic patterns? Here, we study whether CP occurs withsoundless handshapes that are nonethelessphonetic in American Sign Language (ASL), in signers and nonsigners. Using innovative methods and analyses of identification and, crucially, discrimination tasks, we found that both groups separated the soundless handshapes into two classes perceptually but that only the ASL signers exhibited linguistic CP. These findings suggest that CP of linguistic stimuli is based on linguistic categorization, rather than on purely perceptual categorization. 相似文献

The present study was designed to assess children's memory and suggestibility in the context of ongoing child maltreatment investigations. One hundred eighty-nine 3-17-year-olds involved in evaluations of alleged maltreatment were interviewed with specific and misleading questions about an anogenital examination and clinical assessment. For the anogenital examination, children's stress arousal was indexed both behaviorally and physiologically. For all children, individual-difference data were gathered on intellectual and short-term memory abilities, general psychopathology, and dissociative tendencies. Interviewers' ratings were available for a subset of children concerning the amount of detail provided in abuse disclosures. Results indicated that general psychopathology, short-term memory, and intellectual ability predicted facets of children's memory performance. Older compared to younger children evinced fewer memory errors and greater suggestibility resistance. Age was also significantly related to the amount of detail in children's abuse disclosures. Neither dissociation nor stress arousal significantly predicted children's memory. Implications for understanding maltreated children's eyewitness memory are discussed. 相似文献

In light of the selective focus on maternal (vs. paternal) psychopathology as a risk factor for child development, this meta-analysis examines the relative strength of the association between psychopathology in mothers versus fathers and the presence of internalizing and externalizing disorders in children. Associations were stronger between maternal than paternal psychopathology and the presence of internalizing (but not externalizing) problems in children, with all average effect sizes being small in magnitude. Relations were moderated by variables that highlight theoretically relevant differences between psychopathology in mothers versus fathers (e.g., age of children studied, type of parental psychopathology) and by variables related to methodological differences across studies (e.g., method of assessing psychopathology in parents and children, type of sample recruited, familial composition). 相似文献

Blind and blindfolded sighted observers were presented with auditory stimuli specifying target locations. The stimulus was either sound from a loudspeaker or spatial language (e.g., "2 o'clock, 16 ft"). On each trial, an observer attempted to walk to the target location along a direct or indirect path. The ability to mentally keep track of the target location without concurrent perceptual information about it (spatial updating) was assessed in terms of the separation between the stopping points for the 2 paths. Updating performance was very nearly the same for the 2 modalities, indicating that once an internal representation of a location has been determined, subsequent updating performance is nearly independent of the modality used to specify the representation. 相似文献

This article will describe the dynamics taking place in school settings, particularly in classrooms. Literature pertaining to the use of group dynamics in classrooms will be presented. A number of significant group therapy concepts will be addressed. These will include group-as-a-whole, group structure, transference-countertransference, the school and the classroom as holding environments, and therapeutic factors. Some practical dynamic strategies that are meant to strengthen group operations in classroom will also be included. The article will be guided by the writer's personal experiences within school settings and classrooms. 相似文献

A three-factor model of personality pathology was investigated in a clinical sample of 183 female patients in an outpatient eating disorders treatment program. Cluster analysis of MCMI-II personality scales (Millon, 1987) yielded three distinct personality profiles, which were consistent with previous studies. First, 16.9% of the sample comprised a High Functioning cluster, which manifested no clinical elevations on the MCMI-II and had significantly lower scores on the Eating Disorder Inventory (EDI; Garner; 1991) scales than the other two clusters. Second, 49.1% of the sample comprised an Undercontrolled/Dysregulated cluster. Finally, the remaining 34% of the sample comprised an Overcontrolled/Avoidant cluster. This final cluster had significantly higher EDI Ineffectiveness scale scores than the Undercontrolled/Dysregulated cluster group. Cluster membership was not associated with eating disorder subtype, suggesting that there is considerable variance in personality pathology within eating disorder diagnostic categories. 相似文献

Working memory is a set of interactive cognitive processes that maintain information on–line and available for analysis. Part of the system is specialized for maintaining verbal information, a core component of which is thought to be a phonological store. On the basis of the study of patients with acquired brain lesions, this store has been localized to the supramarginal and angular gyri of the speech–dominant hemisphere, and some functional neuroimaging studies support this localization. However, other imaging studies localize the phonological store in a more dorsal region of the parietal lobe. To reconcile these findings, we examined the phonological–similarity effect in two different tasks. A phonological–similarity effect was observed only in the task that involved sequential presentation and explicit verbal rehearsal. We conclude that at least one possible source of the differences in brain activation between different working memory tasks may be differences in phonological processing. 相似文献
