Age of acquisition effects in the semantic processing of pictures   总被引:2,自引:0,他引:2  
In two experiments, we investigated the role of age of acquisition (AoA) in the categorizing of objects in semantic tasks that do not require access to the object names. In both a found inside or outside the house (Experiment 1A) and a smaller or larger than a loaf of bread (Experiment 2A) classification task, objects with earlier-acquired names were categorized more quickly than those with later-acquired names. Experiments 1B and 2B also showed AoA effects on object-naming times for the same pictures. We conclude that AoA operates within the identification process in a fashion not simply restricted to name retrieval. These effects may be better explained in terms of the connectionist model proposed by Ellis and Lambon Ralph (2000) or by accounts that locate AoA within the semantic system (e.g., Brysbaert, Van Wijnendaele, & De Deyne, 2000; van Loon-Vervoorn, 1989).  相似文献

There are various ways of working as an analyst, and there are various ways of utilizing the concept and the phenomena of transference‐countertransference. I hope to draw an adequate picture of a way of working that is called ‘working‐in‐the‐transference’ as distinct from ways of working that ‘analyse transference’. The former has long been practised by many Jungians as well as by many psychoanalysts. As a method, it has aroused controversy in both groups, and is frequently both misunderstood and imitated. It can arouse strong anxiety. It can appear narrow and restrictive. It famously precludes a gamut of activities in which many analysts engage. Is working‐in‐the‐transference old fashioned, or does it deserve to be increasingly appreciated? Can it offer support and validation whilst remaining true to its conception? It was hoped that these questions would be addressed in the clinical material brought to the workshop. The emphasis in the workshop was on active participation and it was hoped that those attending would bring their clinical concerns for discussion.  相似文献

Jane Austen projected some of her personality characteristics onto her fictional namesakes Jane Bennet in the novel Pride and Prejudice and Jane Fairfax in the novel Emma. Wishful fantasy seems satisfied by two attributes of both Janes. They are very beautiful, and they marry rich men they love. A feeling of inferiority was expressed by two attributes of both Janes, depicted as deficient in social communication and subordinate to the heroine of the novel.  相似文献

We examined how the real-life dyadic friendships of 87 children with ADHD and 46 comparison children (76 % boys) aged 7–13 years evolved during a 6-month follow-up period. The methods included friendship quality self-report measures and direct observation of friends’ dyadic behaviors in three structured analogue tasks. At Time 2, the friends of the participants with ADHD reported less positive friendship quality and more conflict with their friends than at Time 1. They were also considerably less satisfied with their friendship than 6 months prior. In contrast, the friends of comparison children reported fewer negative friendship features, more positive friendship features and a slightly greater friendship satisfaction than at Time 1. In sharp contrast with the invited friends’ reports, referred children with ADHD did not report deterioration in their friendship quality over time. Unlike comparison children who significantly reduced violations of game rules between Time 1 and Time 2, children with ADHD broke more game rules during the same period. In negotiating with friends, comparison children, but not children with ADHD, reduced the number of self-centered and insensitive proposals at Time 2. Controlling for Time 1 variance, violations of game rules and a self-centered, insensitive negotiation approach predicted deterioration in friendship quality for children with and without ADHD over time.  相似文献

In infants, eye constriction—the Duchenne marker—and mouth opening appear to index the intensity of both positive and negative facial expressions. We combined eye constriction and mouth opening that co-occurred with smiles and cry-faces (respectively, the prototypic expressions of infant joy and distress) to measure emotional expression intensity. Expression intensity and heart rate were measured throughout the face-to-face/still-face (FFSF) in a sample of infants with prenatal cocaine exposure who were at risk for developmental difficulties. Smiles declined and cry-faces increased in the still-face episode, but the distribution of eye constriction and mouth opening in smiles and cry-faces did not differ across episodes of the FFSF. As time elapsed in the still face episode potential indices of intensity increased, cry-faces were more likely to be accompanied by eye constriction and mouth opening. During cry-faces there were also moderately stable individual differences in the quantity of eye constriction and mouth opening. Infant heart rate was higher during cry-faces and lower during smiles, but did not vary with intensity of expression or by episode. In sum, infants express more intense negative affect as the still-face progresses, but do not show clear differences in expressive intensity between episodes of the FFSF.  相似文献

Electron microscopy has been used to study the microstructures of equilibrated and quenched NiO-TiO2 mixtures containing 5, 10, 15, 20 and 25wt% TiO2. All the specimens contained rocksalt- and spinel-structured phases on a nanometre scale. The microstructure suggests that a nonstoichiometric spinel decomposed during quenching. The 25wt% TiO2 specimen exhibited a lamellar microstructure composed of NiTiO3 and spinelNiO. These phases had the usual orientation relationships, i.e., (111)cubic||(0001)hex and (110)cubic|| (1100>hex. Faceted NiO solid-solution regions with coherent cube-on-cube interfaces with the spinel were found in the four specimens of lower TiO2 contents. When large (15 and 20wt% TiO2), these regions were faceted cuboidal particles. With lower TiO2 contents, these regions were no longer equiaxed and could be interconnected. The specimens were chemically homogeneous on a length scale of about 1mum. Morphological evidence is presented to explain which part of the microstructure most probably already existed in this form during equilibration. In particular, the large-scale NiTiO3 and the spinel lamella in the 25wt% TiO2 material form during long-term equilibration.  相似文献

Goyon et al. [J. Goyon, A. Colin, G. Ovarlez, A. Ajdari and L. Bocquet, Nature 454 (2008) p. 84] have shown that nonlocal effects in the rheology of foams may be accounted for by a modification of the standard (Herschel–Bulkley) model. Here we consider the effects of this modification on the continuum theory of 2d shear localisation. We compute results for various examples, showing that the localisation length is increased, and explore the limiting cases of zero and infinite nonlocality length ξ. Velocity profiles are shown to take an exponential form in the case where ξ is large. As the formulation of the nonlocal continuum model presented in this article is general, it may also be directly applicable to other complex fluids.  相似文献

The first attempt to publish a comprehensive encyclopedia in the Yiddish language began in Berlin in the early 1930s. The editors of Di algemeyne entsiklopedye (The General Encyclopedia) were initially concerned with bringing the latest discoveries from fields such as history, demography, biology, economics and political science to readers in need of assistance in comprehending the larger world. Almost from its inception, however, the project was forced to reconsider its agenda because of the Nazi rise to power. Dropping their original timetable, the first seven volumes were published in Paris (to where its editors first fled after Hitler’s 1933 appointment as Chancellor) and the final volumes were published in New York (to where they subsequently fled the 1940 German invasion of France). With its final volume in 1966, Di algemeyne entsiklopedye totaled twelve volumes—one more than originally planned. Only five ultimately fell within the editors’ original edifying mission, while the remaining seven volumes were dedicated to the subject “Yidn” (“Jews”). Originally planned as a supplement to the Normale volumes, the Yidn series became the primary focus of the Entsiklopedye on account of the rapidly deteriorating circumstances of the Jews in Europe. In this, the Entsiklopedye serves as a useful map of the changing representational imperatives that shaped Jewish scholarship as a consequence of the Holocaust.  相似文献

The research examines the impact of psychographic variables and store characteristics on utilitarian and hedonic shopping value. The findings demonstrate the direct influence of deal proneness and normative interpersonal influences on personal shopping value. Moreover, the study also captures the influence of several store characteristics, such as assortment, after sales service and ambience. The significant influence of shopping value in reducing store switching is also noteworthy. This study also provides evidence relating to how retailer‐controlled variables can influence consumer‐derived shopping value. Results show how each store environment factor influences consumers' overall shopping value and thereby provide an avenue to make strategic adjustments, which in turn can generate a better consumer experience and increased value. The study builds on and extends the previous work carried out relating to antecedents of shopping value by looking at the simultaneous influence of consumer‐level factors as well as retailer‐managed factors. Moreover, the study provides further evidence regarding how shopping value can lessen the dire impact of consumer defection at retail store level. Copyright © 2013 John Wiley & Sons, Ltd.  相似文献
