汉语颠倒词加工中重复知盲发生的水平

以汉语中的颠倒词为材料, 探讨汉语重复知盲的发生水平。采用RSVP方式呈现包含颠倒词对(C1和C2)的句子列表或词语列表, 让被试对列表中的词进行全部报告或报告是否存在重复词, 记录报告C2的正确率。三个实验采用3 (词语的重复性: 颠倒重复、完全重复、不重复) × 2 (颠倒词对的意义相似性: 意义不同、意义相似)两因素被试内设计, 结果在全部报告和报告是否存在重复词的实验中都出现重复性和意义相似性的交互效应, 但不同实验任务, 数据模式不同。该结果表明, 在RSVP任务中, 汉语颠倒词加工存在RB效应, 该效应产生的水平受制于不同的实验任务, 在部分报告任务中, 颠倒词的RB效应发生在知觉水平, 在全部报告任务中, 颠倒词的RB效应发生在语义水平。     

内源性注意和外源性注意对中小学生SNARC效应的影响

采用内源性注意和外源性注意实验范式,以判断数字奇偶为任务,材料为1～9的阿拉伯数字,考察内源性和外源性线索不同注意条件下中小学生的数字加工SNARC效应。结果发现:(1)内源性线索和外源性线索条件下,中小学生在数字加工任务中所表现出来的SNARC效应随着年龄增长逐渐增大;(2)内源性线索和外源性线索注意条件下,各年级学生均表现出显著的SNARC效应;(3)内源性线索非注意条件下,中学生能够表现出显著的SNARC效应,但小学生的SNARC效应不明显;外源性线索非注意条件下,高中生能够表现出显著的SNARC效应,但小学生和初中生的SNARC效应不明显,说明外源性注意对中小学生数字加工SNARC效应的影响比内源性注意大,且对SNARC效应的影响主要表现在较大的数字8和9上。     

动机性信息加工理论及其在工业与组织心理学中的应用

“团队作为信息加工者的观点”认为, 团队执行复杂任务需要经过一系列认知决策, 哪些信息被共享, 以及信息共享和整合的质量, 共同决定团队效能的高低。动机性信息加工理论则进一步提出, 认知动机和社会动机共同决定了哪些信息被共享, 以及信息共享和整合的质量。认知动机决定信息加工的深度, 社会动机决定信息加工的方向, 两种动机共同决定决策质量。这一理论可以很好地整合谈判和创造力领域的研究结果, 并在团队效能领域得到很好的应用。动机性信息加工理论是对双过程模型和“团队作为信息加工者观点”的发展和整合, 并为决策质量的影响因素提供新的分类框架和研究思路。     

音乐情境中自我参照加工的时间特征：来自ERPs的证据

采用事件相关电位技术, 考察在有情境条件下不同层面的自我参照加工的特性及其神经机制。实验发现,在两种音乐情境条件下个体自我参展刺激所激发的P300波幅比集体自我参照刺激和非自我刺激更大,而集体自我参照刺激所激发的P300波幅比非自我刺激更大;两种音乐情境条件下个体自我参照刺激所激发的P300波幅差异显著,而集体自我参照刺激所激发的P300波幅差异不显著。研究结果表明了在不同的情境中,个体自我参照加工的差异较大,表现出不稳定的特征;个体自我参照加工与集体自我参照加工的神经机制是不同的。这些结果还可能表明了相对于集体自我来讲,个体自我是自我的核心层面。     

Auditory processing deficits in children with reading and language impairments: can they (and should they) be treated?

Sixty-five children with specific reading disability (SRD), 25 children with specific language impairment (SLI), and 37 age-matched controls were tested for their frequency discrimination, rapid auditory processing, vowel discrimination, and consonant–vowel discrimination. Subgroups of children with SRD or SLI produced abnormal frequency discrimination (42%), rapid auditory processing (12%), vowel discrimination (23%), or consonant–vowel discrimination (18%) thresholds for their age. Twenty-eight of these children trained on a programme that targeted their specific auditory processing deficit for 6 weeks. Twenty-five of these 28 trainees produced normal thresholds for their targeted processing skill after training. These gains were not explained by gains in auditory attention, in the ability to do psychophysical tasks in general, or by test–retest effects. The 25 successful trainees also produced significantly higher scores on spoken language and spelling tests after training. However, an untrained control group showed test–retest effects on the same tests. These results suggest that auditory processing deficits can be treated successfully in children with SRD and SLI but that this does not help them acquire new reading, spelling, or spoken language skills.     

Synesthesia and number cognition in children

Grapheme-color synesthesia, when achromatic digits evoke an experience of a specific color (photisms), has been shown to be consistent, involuntary, and linked with number concept in adults, yet there have been no comparable investigations with children. We present a systematic study of grapheme-color synesthesia in children aged between 7 and 15 years. Here we show that such children (but not children with phoneme-color synesthesia) experience involuntary difficulties in numerical tasks when digits are presented in colors incongruent with their photisms. Synesthesia in children may thus have important consequences for certain aspects of numerical cognition.     

An own-race advantage for components as well as configurations in face recognition

The own-race advantage in face recognition has been hypothesized as being due to a superiority in the processing of configural information for own-race faces. Here we examined the contributions of both configural and component processing to the own-race advantage. We recruited 48 Caucasian participants in Australia and 48 Chinese participants in Hong Kong, and had them study Caucasian and Chinese faces. After study, they were shown old faces (along with distractors) that were either blurred (isolating configural processing), in which high spatial frequencies were removed from the intact faces, or scrambled (isolating component processing), in which the locations of all face components were rearranged. Participants performed better on the memory test for own-race faces in both the blurred (configural) and scrambled (component) conditions, showing an own-race advantage for both configural and component processing. These results suggest that the own-race advantage in face recognition is due to a general facilitation in different forms of face processing.     

Spirituality and education for global citizenship: developing student teachers’ perceptions and practice

Education for Global Citizenship (E4GC) offers many opportunities to explore spirituality and a sense of how one fits into the world at a range of levels. Beyond the Curriculum Boundaries is a project that enables student teachers to consider E4GC alongside issues of multiculturalism, antiracism and democracy education, with a strong focus on religious education and geography. This paper outlines the ethos behind the project, identifies key elements and themes, appraises student responses, and evaluates key learning points. Student teachers respond to the module in a variety of ways that inform their learning and teaching, and development takes place on both personal and professional levels: as the project has developed the awareness of children’s worldviews and the sense of interconnectedness with others has grown, adding an increasingly spiritual dimension to learning. This article argues that E4GC provides an effective vehicle for supporting the often‐overlooked spiritual dimension of children development.     

Modality and domain specific components in auditory and visual working memory tasks

In the tripartite model of working memory (WM) it is postulated that a unique part system—the visuo-spatial sketchpad (VSSP)—processes non-verbal content. Due to behavioral and neurophysiological findings, the VSSP was later subdivided into visual object and visual spatial processing, the former representing objects’ appearance and the latter spatial information. This distinction is well supported. However, a challenge to this model is the question how spatial information from non-visual sensory modalities, for example the auditory one, is processed. Only a few studies so far have directly compared visual and auditory spatial WM. They suggest that the distinction of two processing domains—one for object and one for spatial information—also holds true for auditory WM, but that only a part of the processes is modality specific. We propose that processing in the object domain (the item’s appearance) is modality specific, while spatial WM as well as object-location binding relies on modality general processes.     

The processing of English regular inflections: Phonological cues to morphological structure

Previous studies suggest that different neural and functional mechanisms are involved in the analysis of irregular (caught) and regular (filled) past tense forms in English. In particular, the comprehension and production of regular forms is argued to require processes of morpho-phonological assembly and disassembly, analysing these forms into a stem plus an inflectional affix (e.g., {fill}+{-ed}), as opposed to irregular forms, which do not have an overt stem+affix structure and must be analysed as full forms [Marslen-Wilson, W. D., & Tyler, L. K. (1997). Dissociating types of mental computation. Nature, 387, 592-594; Marslen-Wilson, W. D., & Tyler, L. K. (1998). Rules, representations, and the English past tense. Trends in Cognitive Science, 2, 428-435]. On this account, any incoming string that shows the critical diagnostic properties of an inflected form - a final coronal consonant (/t/, /d/, /s/, /z/) that agrees in voicing with the preceding segment as in filled, mild, or nilled - will automatically trigger an attempt at segmentation. We report an auditory speeded judgment experiment which explored the contribution of these critical morpho-phonological properties (labelled as the English inflectional rhyme pattern) to the processing of English regular inflections. The results show that any stimulus that can be interpreted as ending in a regular inflection, whether it is a real inflection (filled-fill), a pseudo-inflection (mild-mile) or a phonologically matched nonword (nilled-nill), is responded to more slowly than an unambiguously monomorphemic stimulus pair (e.g., belt-bell). This morpho-phonological effect was independent of phonological effects of voicing and syllabicity. The findings are interpreted as evidence for a basic morpho-phonological parsing process that applies to all items with the criterial phonological properties.
