Predictors of timed picture naming in Chinese

We report normative data collected from Mainland Chinese speakers for 232 objects taken from Snodgrass and Vanderwart (1980). These data include adult ratings of concept familiarity, age of acquisition (AoA), printedword frequency, and word length (in syllables), as well as measures of rated visual complexity, image agreement, and name agreement. We then examined timed picture naming of these objects with native Chinese speakers in Beijing in two experiments using line drawings and colored pictures. In both experiments, the variables name agreement, rated concept familiarity, and AoA made significant independent contributions to naming latency in multiple regression analyses. We observed a correlation ofr=.85 between naming latency with line drawings and colored pictures and a reduced effect of image agreement on naming when colored pictures were presented. We discuss the implications of our findings for the study of lexical processing in Chinese. Normative data for 232 Chinese nouns may be downloaded from www.psychonomic.org/archive     

Do “mudsplashes” induce tactile change blindness?

The phenomenon of change blindness (the surprising inability of people to correctly perceive changes between consecutively presented displays), primarily reported in vision, has recently been shown to occur for positional changes presented in tactile displays as well. Here, we studied people’s ability to detect changes in the number of tactile stimuli in successively presented displays composed of one to three stimuli distributed over the body surface. In Experiment 1, a tactile mask consisting of the simultaneous activation of all seven possible tactile stimulators was sometimes presented between the two to-be-discriminated tactile displays. In Experiment 2, a “mudsplash” paradigm was used, with a brief irrelevant tactile distractor presented at the moment of change of the tactile display. Change blindness was demonstrated in both experiments, thus showing that the failure to detect tactile change is not necessarily related to (1) the physical disruption between consecutive events, (2) the effect of masking covering the location of the change, or (3) the erasure or resetting of the information contained within an internal representation of the tactile display. These results are interpreted in terms of a limitation in the number of spatial locations/events that can be consciously accessed at any one time. This limitation appears to constrain change-detection performance, no matter the sensory modality in which the stimuli are presented.     

Multisensory numerosity judgments for visual and tactile stimuli

To date, numerosity judgments have been studied only under conditions of unimodal stimulus presentation. It is therefore unclear whether the same limitations on correctly reporting the number of unimodal visual or tactile stimuli presented in a display might be expected under conditions in which participants have to count stimuli presented simultaneously in two or more different sensory modalities. In Experiment 1, we investigated numerosity judgments using both unimodal and bimodal displays consisting of one to six vibrotactile stimuli (presented over the body surface) and one to six visual stimuli (seen on the body via mirror reflection). Participants had to count the number of stimuli regardless of their modality of presentation. Bimodal numerosity judgments were significantly less accurate than predicted on the basis of an independent modality-specific resources account, thus showing that numerosity judgments might rely on a unitary amodal system instead. The results of a second experiment demonstrated that divided attention costs could not account for the poor performance in the bimodal conditions of Experiment 1. We discuss these results in relation to current theories of cross-modal integration and to the cognitive resources and/or common higher order spatial representations possibly accessed by both visual and tactile stimuli.     

表象对初中一年级学生成语理解影响的实验研究

以初中一年级学生为被试,从小学语文六年制课本中选取高熟悉度、高表象性的成语为实验材料,采用三因素混合设计探讨表象对不同透明度成语理解的影响。研究结果表明:初中一年级学生能据所呈现的成语形成表象,并报告出较高的表象清晰度,但表象清晰度与成语理解成绩之间的相关不显著。高透明度成语比低透明度成语更容易被理解。通过有意表象的学习,成语理解成绩得到了显著的提高,尤其是高透明度成语。     

论文物的使用价值及其源泉

文物不同于现实物品,也不同于一般物品,文物是在时间的推移和空间的变迁中逐渐形成的。文物具有四种使用价值,即自然使用价值、审美使用价值、增值使用价值和信息使用价值,除自然使用价值之外,其余三种使用价值的发展变化都直接与时空条件有关,而与人的劳动、自然力的作用关系并不明确。因此,时空条件是文物使用价值的重要源泉。     

Not wallowing in misery – retractions of negative misinformation are effective in depressive rumination

People often continue to rely on misinformation in their reasoning after they have acknowledged a retraction; this phenomenon is known as the continued-influence effect. Retractions can be particularly ineffective when the retracted misinformation is consistent with a pre-existing worldview. We investigated this effect in the context of depressive rumination. Given the prevalence of depressotypic worldviews in depressive rumination, we hypothesised that depressive rumination may affect the processing of retractions of valenced misinformation; specifically, we predicted that the retraction of negative misinformation might be less effective in depressive ruminators. In two experiments, we found evidence against this hypothesis: in depressive ruminators, retractions of negative misinformation were at least as effective as they were in control participants, and more effective than retractions of positive misinformation. Findings are interpreted in terms of an attentional bias that may enhance the salience of negative misinformation and may thus facilitate its updating in depressive rumination.     

时间延迟对故事情境关联虚假记忆的影响

研究以故事情境短文为实验材料,探讨了即时与延时48h后虚假记忆变化表现及其与真实记忆相分离的认知神经机制。结果表明,虚假记忆在延迟48h后诱发的LPC走向比即时更正性;即时条件虚假记忆与真实记忆认知加工相分离表现在有意回想加工及额叶后提取加工阶段,延迟48h后仅表现在额叶后提取加工阶段。上述结果为虚假记忆存在随时间变化及其与真实记忆相分离提供了电生理证据。
