The differentiation of subtypes of primary progressive aphasia (PPA) remains challenging. We aimed to identify optimum neuropsychological measures for characterizing PPA, to examine the relationship between behavioural change and subtypes of PPA and to determine whether characteristic profiles of language, working memory, and behavioural changes occur in PPA. Forty-seven patients with PPA and multi-domain Alzheimer's disease (AD) together with 19 age-matched controls underwent a large battery of working memory and language tests. We found that simple tasks of sentence ordering, narrative production, and buccofacial praxis were particularly useful in differentiating non-fluent/agrammatic variant PPA (nfvPPA) from other PPA subtypes, whereas a test of single word comprehension was useful in detecting semantic dementia (SD). No individual tests were discriminating for logopenic variant PPA (lvPPA) relative to nfvPPA. LvPPA and multidomain AD exhibited similar language profiles. A principal components analysis revealed that characteristic PPA profiles extended beyond the realms of language, in particular, the presence of apraxia in nfvPPA, behavioural changes in SD, and working memory deficits in lvPPA. These findings suggest that not all tests are equally discriminatory for PPA and highlight the importance of a test profile in differentiating PPA. These results also support the view that lvPPA is a focal form of AD and emphasize the difficulties classifying lvPPA. 相似文献

Beyond the qualitative paradigm: A framework for introducing diversity within qualitative psychology
The case for qualitative research in psychology is considered. We argue against the idea that qualitative research is merely a matter of technique or method, and question the utility of viewing it as a unitary paradigm. Rather, the links between epistemology, methodology, and method are explored within three theorized strands of qualitative inquiry, making reference to illustrative projects. Each strand is organized around a different approach to the issues of justifying and warranting psychological knowledge: (1) reliability and validity; (2) generativity and grounding; and (3) discourse and reflexivity. These are exemplified in Miles and Huberman's ‘data display’ model, Glaser and Strauss' method of ‘grounded theory’, and in various forms of ‘discourse’ analysis. Reflections upon points of contact between the three strands address two main issues: (1) rendering research publicly accountable; and (2) challenging relativism. 相似文献

对变化/分割模型的检验(I) 总被引:9,自引:1,他引:8
用两个实验对变化/分割模型进行了检验。实验1控制目标时距和该时距内的填充数字系列,操纵数字系列的分割段数;实验2控制目标时距内的填充数字系列的间距,操纵目标时距及其中填充数字系列的分割段数,要求被试用再现法和多数估计法分别复制目标时距,并进行立即估计和延迟估计。结果显示:与存储容量模型和加工时间模型相比较,变化/分割模型对时间估计的解释具有更高的预测效度 相似文献

Pascals wager is expounded as a paradigm case of a practical,decision-theoretical argument for acting as if a proposition is true when wehave no theoretical reasons to accept or reject it (1.1.–1.2.). Thoughthe paradigm is fallacious in various respects there are valid and adequatearguments for acting as if certain propositions are true: that theoreticalentities exist, that there are material perceptual objects, that the worldis uniform across time (1.3). After this analysis of examples the authorsgeneral approach for developing criteria for the validity and adequacy oftypes of argument (2.1.) is applied: Having discussed some problems(2.2.–2.3.), a general epistemic principle for such pascal argumentsis developed, which characterizes their premisses and, if introduced as anadditional premiss, can make them deductively valid (2.4). 相似文献

Many English Caribbean families in the United States are referred for therapy because of difficulties related to their adaptation to a new country/culture. This paper focuses on the intra-familial, and the family-larger system transitional/adjustment difficulties experienced by these families and presents issues specific to therapy with them. Effective therapy with English Caribbean families and their subsystems requires that therapists communicate to these families an understanding of their concerns, be knowledgeable about heterogeneity in cultural values and traditions, and create a therapeutic atmosphere in which families can feel valued and respected. Recommendations for therapists are presented and discussed. 相似文献

The introduction of Linear Logic extends the Curry-Howard Isomorphism to intensional aspects of the typed functional programming. In particular, every formula of Linear Logic tells whether the term it is a type for, can be either erased/duplicated or not, during a computation. So, Linear Logic can be seen as a model of a computational environment with an explicit control about the management of resources.This paper introduces a typed functional language ! and a categorical model for it.The terms of ! encode a version of natural deduction for Intuitionistic Linear Logic such that linear and non linear assumptions are managed multiplicatively and additively, respectively. Correspondingly, the terms of ! are built out of two disjoint sets of variables. Moreover, the -abstractions of ! bind variables and patterns. The use of two different kinds of variables and the patterns allow a very compact definition of the one-step operational semantics of !, unlike all other extensions of Curry-Howard Isomorphism to Intuitionistic Linear Logic. The language ! is Church-Rosser and enjoys both Strong Normalizability and Subject Reduction.The categorical model induces operational equivalences like, for example, a set of extensional equivalences.The paper presents also an untyped version of ! and a type assignment for it, using formulas of Linear Logic as types. The type assignment inherits from ! all the good computational properties and enjoys also the Principal-Type Property. 相似文献

Behavioral and Emotional Problems in Young Preschoolers: Cross-Cultural Testing of the Validity of the Child Behavior Checklist/2-3 总被引:6,自引:0,他引:6

The cross-cultural validity of the Child Behavior Checklist for Ages 2-3 (CBCL/2-3) was tested in three Dutch samples of children referred to mental health services, from the general population, and from a twin study. Six scales were derived from factor analyses and labeled Oppositional, Aggressive, and Overactive, which constituted a broadband Externalizing grouping; Withdrawn/Depressed and Anxious, which constituted a broadband Internalizing grouping; and Sleep Problems. Internal consistencies of the scales, their test-retest reliabilities, interparent agreement, discriminative power, predictive relations with problem ratings 2 years later, and relations to other instruments designed to measure general development and behavior problems were adequate, and highly comparable to psychometric properties in American samples. It was concluded that across languages and cultures behavioral/emotional problems of young preschoolers may be adequately assessed with the CBCL/2-3. 相似文献

Recovery of single word comprehension: CT-scan correlates 总被引:7,自引:0,他引:7
9tory comprehension for single words, as measured by the BDAE Word Discrimination subtest, was studied longitudinally in a group of 37 aphasic patients. The majority of the patients had impaired performance at 1 month postonset, but recovery by Month 6 postonset was quite striking. Damage to Wernicke's area did not preclude recovery of single word comprehension to within the normal range. Only patients with very extensive left hemisphere lesions had incomplete recovery of single word comprehension. 相似文献
