Using Conger’s family stress model as a theoretical framework, a series of mediated associations among economic hardship, perceived economic pressure, parental depression, marital conflict, psychologically controlling parenting, and children’s reticent behaviors in Romanian families were studied. The sample consisted of 121 Romanian mothers and fathers of 4–5-year-old children. Children’s kindergarten teachers living in urban and rural locations evaluated child reticence. Findings generally support the family stress model. Structural equation modeling showed that after controlling for living in a rural location, economic pressure was indirectly linked with marital conflict through depression. Depression was indirectly related to psychological control through marital conflict, and marital conflict was indirectly linked to child reticence through psychological control. Directions for future research and recommendations for interventions and public policy are described.  相似文献

Theories of language production have long been expressed as connectionist models. We outline the issues and challenges that must be addressed by connectionist models of lexical access and grammatical encoding, and review three recent models. The models illustrate the value of an interactive activation approach to lexical access in production, the need for sequential output in both phonological and grammatical encoding, and the potential for accounting for structural effects on errors and structural priming from learning.  相似文献

Presentism has received much scrutiny of late, yet little has been said of its definition. Many assume that it means simply that all that exists, exists at present. However, this definition will not do. It is defective in a multiplicity of ways. I consider and reject each of a number of intuitive ways in which to amend it. Each carries us a bit closer to our goal, but not until the end do we reach a definition that is wholly satisfactory. The final definition has this remarkable feature: it has us posit abstracta of two kinds, namely, times and haecceities.  相似文献

Two versions of a distributed-memory model, one for associative information and one for serial-order information, leave open the question of whether there are two different modes of operation or only one. An analysis of these two versions showed that differential predictions emerge when one considers the role of item information. To test these predictions, a standard item-recognition task (Sternberg, 1966) was embedded in a paired-associate probe-recognition task, a serial-order probe-recognition task, or both. The item-recognition serial-position curves were quite different in the paired-associate and the serial-order conditions, and followed the paired-associate condition when the two were combined. In general, the results were consistent with the predictions of the distributed-memory models, and supported the idea of different modes of operation rather than a single common mode of operation.  相似文献

The "difference position" holds that clinical research and therapeutic medical practice are sufficiently distinct activities to require different ethical rules and principles. The "similarity position" holds instead that clinical investigators ought to be bound by the same fundamental principles that govern therapeutic medicine--specifically, a duty to provide the optimal therapeutic benefit to each patient or subject. Some defenders of the similarity position defend it because of the overlap between the role of attending physician and the role of investigator in a research trial. This overlap is maximal when the same physician occupies both roles with respect to a particular patient-subject. We address the ethical tensions inherent in that role conflict and argue that the tensions are real but manageable. The difference position provides a sound ethical framework within which to manage those tensions, while the similarity position is unsatisfactory because it seeks to deny the existence of the tensions.  相似文献

Although photographic assessment has been found to be reliable in assessing hair loss in Trichotillomania, the validity of this method is unclear, particularly for gauging progress in treatment. The current study evaluated the psychometric properties of photographic assessment of change in Trichotillomania. Photographs showing hair loss of adults with Trichotillomania were taken before and after participating in a clinical trial for the condition. Undergraduate college students (N?=?211) rated treatment response according to the photos, and additional archival data on hair pulling severity and psychosocial health were retrieved from the clinical trial. Photographic assessment of change was found to possess fair reliability (ICC?=?0.53), acceptable criterion validity (r?=?0.51), good concurrent validity (r?=?0.30–0.36), and excellent incremental validity (ΔR 2?=?8.67, p?<?0.01). In addition, photographic measures were significantly correlated with change in quality of life (r?=?0.42), and thus could be considered an index of the social validity of Trichotillomania treatment. Gender of the photo rater and pulling topography affected the criterion validity of photographic assessment (partial η 2?=?0.05–0.11). Recommendations for improving photographic assessment and future directions for hair pulling research are discussed.  相似文献
