面孔识别中的构形加工与特征加工

面孔信息的分类方法一直复杂多样, 相关研究数据丰富, 但所用概念混杂。构形加工与特征加工作为使用最频繁的分类方法, 其可靠性越来越受研究者们关注。从近40年来的相关文献中选择引用率高的文献做参考, 遵循不同研究方法相互印证的原则分析数据, 提出构形加工与特征加工的区分是面孔识别中重要并且可靠的加工类型划分, 但确认两者在知觉加工上的先后关系以及在个体发展上的先后顺序尚缺乏稳定一致性的实验依据。     

词汇语音学习的影响因素

摘要 词汇语音的学习受哪些因素的影响是心理语言学研究中一个重要的问题。语音回路理论认为,语音短时记忆在词汇语音的学习过程中发挥着关键性的作用,语音短时记忆能力越好越有助于词汇的学习;语音敏感性假说认为,语音意识是影响儿童词汇发展及学习的重要因素;另外一些研究者认为,语音知识可能发挥着更为基础和关键的作用,最近的研究则更加强调几种因素如何相互作用影响词汇语音的学习。本文最后提出了该领域需要进一步研究的问题。     

面孔识别的认知发展机制

关于面孔识别能力的认知发展机制问题,目前存在两种不同的观点。一种是面孔特殊性发展理论,认为儿童的面孔识别之所以不如成人,是由于儿童和成人对面孔的加工方式不同,代表性理论有部分加工-结构加工理论,内部特征-外部特征加工理论,多维空间理论等。另一种是一般认知能力观点,认为儿童很早就具备了成人式的面孔加工方式,之后面孔识别任务中成绩的提高都可归因于一般认知能力的发展。在对两种观点进行评述的基础上,对未来的面孔识别研究提出了建议。     

幻忆现象研究现状述评

幻忆(Déjà vu)是指任何对目前体验的一种不适宜的熟悉感, 并伴随着对过去体验的不确定感。年龄、梦、教育水平、旅行经历、生理状况和药物都会对幻忆产生造成影响。研究发现, 内侧颞叶和嗅内皮质与幻忆有着紧密的联系。目前主要通过知觉分离范式、情景再现范式、单成分元素交互作用范式、无辨别再认范式和催眠范式来研究幻忆现象。幻忆的研究仍然存在着若干问题, 这些问题需要进一步探讨。     

No evidence for a role of reconsolidation in updating of paired associates

Reconsolidation theory states that memories are labilized through reactivation, making them prone to change, before being re-consolidated. When information in memory requires updating, reconsolidation theory therefore predicts that reminders of previously learned information should facilitate updating of that information and should thus improve memory for the updated information. In two experiments, we tested this prediction by investigating memory for word pairs over a short time-scale. Participants studied word pairs (A–B), some of which were subsequently updated with word pairs that shared the first word (A–C). Half of the A–C pairs received a pre-study reminder of the first word in the pair so as to reactivate and labilize A–B memory. In a recognition memory test targeting the A–C list, reminders by and large had no effect on memory. Results thus failed to support the predictions of reconsolidation theory.     

推理的启发式再认新模式

Sensitivity to the acoustic correlates of lexical stress and their relationship to reading in skilled readers

The role of suprasegmental information in reading processes is a growing area of interest, and sensitivity to lexical stress has been shown to explain unique variance in reading development. However, less is known about its role in skilled reading. This study aimed to investigate the acoustic features of suprasegmental information using a same/different cross-modal matching task. Sixty-four adult participants completed standardized measures of reading accuracy, reading speed, and comprehension and performed an experimental task. The experimental task required the participants to identify whether non-speech acoustic sequences matched the characteristics of written words. The findings indicated differences in responses depending on where the lexical stress was required for the word. Moreover, evidence was found to support the view that amplitude information is part of the word knowledge retrieval process in skilled reading. The findings are discussed relative to models of reading and the role of lexical stress in lexical access.     

重症手足口病的早期识别与处理

手足口病(hand-foot-mouth disease,HFMD)是由肠道病毒[以柯萨奇A组16型(Coxsackievirus A16,CoxA16)、肠道病毒71型(Enterovirus 71,EV71)多见]引起的急性传染病,而重症多由EV71感染引起。由于EV71的高度嗜神经性,重症者可合并中枢神经系统(central nervous system,CNS)损害、急性肺水肿/出血等。现就重症手足口病的早期识别与处理进行简要综述。     

Investigations of hemispheric specialization of self-voice recognition

Three experiments investigated functional asymmetries related to self-recognition in the domain of voices. In Experiment 1, participants were asked to identify one of three presented voices (self, familiar or unknown) by responding with either the right or the left-hand. In Experiment 2, participants were presented with auditory morphs between the self-voice and a familiar voice and were asked to perform a forced-choice decision on speaker identity with either the left or the right-hand. In Experiment 3, participants were presented with continua of auditory morphs between self- or a familiar voice and a famous voice, and were asked to stop the presentation either when the voice became "more famous" or "more familiar/self". While these experiments did not reveal an overall hand difference for self-recognition, the last study, with improved design and controls, suggested a right-hemisphere advantage for self-compared to other-voice recognition, similar to that observed in the visual domain for self-faces.
