Three experiments were conducted to examine the effect of phonological similarity in simple and complex memory span tasks.
In Experiment 1, participants performed either a simple or a complex span task, and the memoranda within lists were either phonologically
similar or distinct. Phonologically similar lists consisted of words that rhymed.The simple span task was word span. There
were two complex span tasks; one was the original reading span task, and the other was a variant of reading span in which
all the sentences within a list were contextually related. The classic phonological similarity decrement was observed in word
span. In contrast, phonological similarity facilitation was observed in both versions of reading span. This facilitation effect
was further investigated in Experiment 2 using two new versions of reading span. In Experiment 2, the sentences in reading span were either short or long, and the memoranda were presented separately from, and were unrelated
to, the sentences. Again, words within phonologically similar lists rhymed, and again, facilitation was observed. In Experiment
3, phonological similarity was operationalized in terms of feature overlap, rather than rhyme. The classic phonological similarity
decrement was still observed in word span, but facilitation was not observed in complex span. The results suggest that phonological
similarity, when operationalized using words that rhyme, serves as a list retrieval cue and that complex span tasks are more
dependent on cue-driven memory retrieval mechanisms than are simple span tasks. 相似文献

This paper presents the problems of representation and lack of representation in treating Holocaust survivors, through clinical vignettes and various theoreticians. The years of Nazi persecution and murder brought about a destruction of symbolization and turning inner and external reality into the Thing itself, the concrete, or, in Lacan’s words, ‘The Thing’. The paper presents two ideas related to praxis as well as theory in treating Holocaust survivors: the first is related to the therapist’s treatment of the Holocaust nightmare expressing the traumatic events just as they happened 63 years previously; the second deals with the attempt at subjectification, in contrast to the objectification forced by the Nazis on their victims. 相似文献

Best-worst scaling is a judgment format in which participants are presented with a set of items and have to choose the superior and inferior items in the set. Best-worst scaling generates a large quantity of information per judgment because each judgment allows for inferences about the rank value of all unjudged items. This property of best-worst scaling makes it a promising judgment format for research in psychology and natural language processing concerned with estimating the semantic properties of tens of thousands of words. A variety of different scoring algorithms have been devised in the previous literature on best-worst scaling. However, due to problems of computational efficiency, these scoring algorithms cannot be applied efficiently to cases in which thousands of items need to be scored. New algorithms are presented here for converting responses from best-worst scaling into item scores for thousands of items (many-item scoring problems). These scoring algorithms are validated through simulation and empirical experiments, and considerations related to noise, the underlying distribution of true values, and trial design are identified that can affect the relative quality of the derived item scores. The newly introduced scoring algorithms consistently outperformed scoring algorithms used in the previous literature on scoring many-item best-worst data. 相似文献

The literature on risk perception in women from high-risk breast cancer families reveals persistent over-estimation of risk, even after counseling. In this study, a communication aid was designed to facilitate discussion of risk between clinical geneticists and genetic counselors and women from this high-risk population. Method: Stage 1. The aid was developed by an expert panel of clinical geneticists, genetic counselors, psychologists, an epidemiologist, an oncologist, linguists and a consumer. It was guided by the international literature on risk communication and a large multi-centre Australian study of risk communication. The 13 page full-color communication aid used varying formats of words, numbers, graphs and pie-charts to address (a) the woman’s subjective risk; (b) the population risk of breast cancer; c) the risk of inherited breast cancer; (d) the cumulative risk for women with BRCA1 and BRCA2 mutations; (e) family risk factors; (f) the woman’s suitability for genetic testing; (h) screening and management recommendations, and (i) a re-assessment of the woman’s subjective risk. Stage 2: A before–after pilot study of 38 women who were unaffected with breast cancer and were attending four Australian familial cancer clinics was undertaken. Baseline and follow-up questionnaires were completed by 27 women. Outcomes were compared to those observed in 107 similar women undergoing genetic counseling without the communication aid in 2001. Results: The risk communication aid appears to be beneficial; breast cancer genetics knowledge improved in some areas and importantly, risk perceptions improved in the cohort receiving the communication aid. Psychological measures showed no difference in anxiety or depression between the group receiving the communication aid and the comparison cohort. Women and clinicians were very positive about the usefulness of the communication aid as an adjunct to the genetic counseling consultation. 相似文献

Confidence intervals (CIs) give information about replication, but many researchers have misconceptions about this information. One problem is that the percentage of future replication means captured by a particular CI varies markedly, depending on where in relation to the population mean that CI falls. The authors investigated the distribution of this percentage for varsigma known and unknown, for various sample sizes, and for robust CIs. The distribution has strong negative skew: Most 95% CIs will capture around 90% or more of replication means, but some will capture a much lower proportion. On average, a 95% CI will include just 83.4% of future replication means. The authors present figures designed to assist understanding of what CIs say about replication, and they also extend the discussion to explain how p values give information about replication. 相似文献

Natural scenes contain far more information than can be processed simultaneously. Thus, our visually guided behavior depends crucially on the capacity to attend to relevant stimuli. Past studies have provided compelling evidence of functional overlap of the neural mechanisms that control spatial attention and saccadic eye movements. Recent neurophysiological work demonstrates that the neural circuits involved in the preparation of saccades also play a causal role in directing covert spatial attention. At the same time, other studies have identified separable neural populations that contribute uniquely to visual and oculomotor selection. Taken together, all of the recent work suggests how visual and oculomotor signals are integrated to simultaneously select the visual attributes of targets and the saccades needed to fixate them. 相似文献
