Research suggests that a feature-matching process underlies cue familiarity-detection when cued recall with graphemic cues fails. When a test cue (e.g., potchbork) overlaps in graphemic features with multiple unrecalled studied items (e.g., patchwork, pitchfork, pocketbook, pullcork), higher cue familiarity ratings are given during recall failure of all of the targets than when the cue overlaps in graphemic features with only one studied target and that target fails to be recalled (e.g., patchwork). The present study used semantic feature production norms (McRae et al., Behavior Research Methods, Instruments, & Computers, 37, 547–559, 2005) to examine whether the same holds true when the cues are semantic in nature (e.g., jaguar is used to cue cheetah). Indeed, test cues (e.g., cedar) that overlapped in semantic features (e.g., a_tree, has_bark, etc.) with four unretrieved studied items (e.g., birch, oak, pine, willow) received higher cue familiarity ratings during recall failure than test cues that overlapped in semantic features with only two (also unretrieved) studied items (e.g., birch, oak), which in turn received higher familiarity ratings during recall failure than cues that did not overlap in semantic features with any studied items. These findings suggest that the feature-matching theory of recognition during recall failure can accommodate recognition of semantic cues during recall failure, providing a potential mechanism for conceptually-based forms of cue recognition during target retrieval failure. They also provide converging evidence for the existence of the semantic features envisaged in feature-based models of semantic knowledge representation and for those more concretely specified by the production norms of McRae et al. (Behavior Research Methods, Instruments, & Computers, 37, 547–559, 2005). 相似文献

This paper responds to Dan Hutto’s paper, ‘Narrative Self-Shaping: a Modest Proposal’. Hutto there attacks the “strong” narrativism defended in my recent book, ‘Self, Value and Narrative’ and in recent work by Marya Schechtman. I rebut Hutto’s argument that non-narrative forms of evaluative self-shaping can plausibly be conceived, and defend the notion of implicit narrative against his criticisms. I conclude by briefly indicating some difficulties that arise for the “modest” form of narrativism that Hutto defends. 相似文献

The study investigated different types of awareness of memory dysfunction in dementia, specifically judgements concerning memory task performance or appraisal of everyday memory functioning and also exploring the neuropsychological correlates of such awareness. This was investigated in 76 people with dementia, comprising 46 patients with Alzheimer's disease (AD) and 30 patients with vascular dementia (VaD). The Memory Awareness Rating Scale (Clare et al., 2002, Neuropsychol Rehabil, 12, 341–362) was used, which includes an Objective‐Judgement Discrepancy (OJD) technique involving comparison of subjective evaluation of performance on specific memory tasks with actual performance, and a Subjective Rating Discrepancy (SRD) technique, which compares self versus informant judgement of everyday memory function. The AD and VaD groups showed lower awareness than a normal control group for both types of measures, the AD group showing less awareness than the VaD group on the OJD measure. Regression analyses supported associations for both groups between memory impairment and the OJD measure and between naming impairment and the SRD measure. The findings are discussed in terms of neurocognitive theories accounting for loss of awareness in dementia. 相似文献

Evidence for a bilingual advantage in executive control has led to the suggestion that being bilingual might protect against late-life cognitive decline. We assessed the performance of socially homogeneous groups of older (≥60 years) bilingual Welsh/English (n?=?50) and monolingual English (n?=?49) speakers on a range of executive control tasks yielding 17 indices for comparison. Effect sizes (>.2) favoured monolinguals on 10 indices, with negligible differences observed on the remaining 7 indices. Univariate analyses indicated that monolinguals performed significantly better on 2 of 17 indices. Multivariate analysis indicated no significant overall differences between the two groups in performance on executive tasks. Older Welsh bilinguals do not show a bilingual advantage in executive control, and where differences are observed, these tend to favour monolinguals. A possible explanation may lie in the nature of the socio-linguistic context and its influence on cognitive processing in the bilingual group. 相似文献

It is generally assumed that the latent trait is normally distributed in the population when estimating logistic item response theory (IRT) model parameters. This assumption requires that the latent trait be fully continuous and the population homogenous (i.e., not a mixture). When this normality assumption is violated, models are misspecified, and item and person parameter estimates are inaccurate. When normality cannot be assumed, it might be appropriate to consider alternative modeling approaches: (a) a zero-inflated mixture, (b) a log-logistic, (c) a Ramsay curve, or (d) a heteroskedastic-skew model. The first 2 models were developed to address modeling problems associated with so-called quasi-continuous or unipolar constructs, which apply only to a subset of the population, or are meaningful at one end of the continuum only. The second 2 models were developed to address non-normal latent trait distributions and violations of homogeneity of error variance, respectively. To introduce these alternative IRT models and illustrate their strengths and weaknesses, we performed real data application comparing results to those from a graded response model. We review both statistical and theoretical challenges in applying these models and choosing among them. Future applications of these and other alternative models (e.g., unfolding, diffusion) are needed to advance understanding about model choice in particular situations. 相似文献

When bivariate normality is violated, the default confidence interval of the Pearson correlation can be inaccurate. Two new methods were developed based on the asymptotic sampling distribution of Fisher's z′ under the general case where bivariate normality need not be assumed. In Monte Carlo simulations, the most successful of these methods relied on the (Vale & Maurelli, 1983, Psychometrika, 48, 465) family to approximate a distribution via the marginal skewness and kurtosis of the sample data. In Simulation 1, this method provided more accurate confidence intervals of the correlation in non-normal data, at least as compared to no adjustment of the Fisher z′ interval, or to adjustment via the sample joint moments. In Simulation 2, this approximate distribution method performed favourably relative to common non-parametric bootstrap methods, but its performance was mixed relative to an observed imposed bootstrap and two other robust methods (PM1 and HC4). No method was completely satisfactory. An advantage of the approximate distribution method, though, is that it can be implemented even without access to raw data if sample skewness and kurtosis are reported, making the method particularly useful for meta-analysis. Supporting information includes R code. 相似文献
