13~15岁儿童对愤怒表情觉察的特点

本研究以13~15岁的青少年为被试,使用视觉搜索任务,要求被试对呈现在愤怒、愉快和中性图示面孔表情图片中的表情相同和表情不同的图片进行判断,从而检验青少年对愤怒表情、愉快表情和中性表情觉察效果的差异.结果表明:(1)当呈现相同的表情时,青少年对愤怒表情的图片的觉察比对愉快表情的图片的觉察要慢.(2)当呈现的表情中有不同的表情时,青少年对愤怒表情的觉察要快于对愉快表情的觉察.(3)青少年对愤怒表情的搜索斜率低于对愉快表情的搜索斜率.对愤怒表情的搜索和对愉快表情的搜索都为系列搜索.     

浅谈易学文化的传承与发展

本文在综观易学文化发展历史和研究现状的基础上,探讨了当代易学文化传承与发展过程中的主要问题,强调把易学作为独立学科加以科学研究的重要性和必要性,并明确提出一系列观点:应该合理界定易学的名称范畴,密切关注易学文化的传承问题,逐步拟定易学的发展目标.     

汉字语音关联对错误记忆的影响

应用DRM范式, 研究单个汉字语音关联对错误记忆的影响。实验一中, 学习阶段呈现的各字表汉字与未呈现的诱饵字具有相同音节。再认测试发现, 被试对诱饵字产生了明显的错误再认。实验二发现, 当各学习字表内的汉字拥有相同声母或相同韵母时, 被试对相应的两种诱饵字也能产生明显的错误再认, 并且其效应与音节相同时基本一样。这些结果说明, 汉字的语音关联可以诱发错误记忆现象, 但其效应并不随语音相似度的增加而增加。研究提示, 错误记忆可以来源于较低层次的基于知觉的加工; 中文语音网络虽然易于激活, 但激活程度有限。     

刺激的视觉显著性和奖赏价值对眼跳的影响

本研究旨在探索刺激的视觉显著性和奖赏价值分别在协同和竞争的条件下对眼跳过程的影响。实验材料为成对的Gabor图案,要求被试选择具有更高奖赏价值的图案,并记录下其眼动过程。实验分为协同条件和竞争条件。结果发现,在不同实验条件下,奖赏价值对眼跳命中率和潜伏期均存在显著效应;视觉显著性的效应则在不同实验条件下出现了分离。刺激驱动过程和目标驱动过程对眼动行为的影响可能是互相区别的两种不同模式。     

The effects of increasing semantic-associate list length on the Deese–Roediger–McDermott false recognition memory: Dual false-memory process in retrieval from sub- and supraspan lists

In this study, the number of semantic associates in Deese–Roediger–McDermott (DRM) lists was varied from 4 to 14 in a modified Sternberg paradigm. The false alarm (FA) and correct rejection (CR) reaction time (RT)/memory-set size (MSS) functions of critical lures showed a cross-over interaction at approximately MSS 7, suggesting a reversal of the relative dominance between these two responses to the critical lure at this point and also indicating the location of the boundary between the sub- and supraspan MSS. For the subspan lists, FA to critical lures was slower than CR, suggesting a slow, strategic mechanism driving the false memory. Conversely, for the supraspan lists, critical lure FA was faster than its CR, suggesting a spontaneous mechanism driving the false memory. Results of two experiments showed that an automatic, fast, and a slow, controlled process could be error-prone or error-corrective, depending on the length of the DRM memory list. Thus there is a dual retrieval process in false memory as in true memory. The findings can be explained by both the activation/monitoring and the fuzzy-trace theories.     

The contribution of facial regions to judgements of happiness and trustworthiness from dynamic expressions

What expressive facial features and processing mechanisms make a person look trustworthy, relative to happy? Participants judged the un/happiness or un/trustworthiness of people with dynamic expressions in which the eyes and/or the mouth unfolded from neutral to happy or vice versa. Faces with an unfolding smile looked more trustworthy and happier than faces with a neutral mouth, regardless of the eye expression. Unfolding happy eyes increased both trustworthiness and happiness only in the presence of a congruent unfolding smiling mouth. Nevertheless, the contribution of the mouth was greater for happiness than for trustworthiness; and the mouth was especially visually salient for expressions favouring happiness more than trustworthiness. We conclude that the categorisation of facial happiness is more automatically driven by the visual saliency of a single feature, that is, the smiling mouth, while perception of trustworthiness is more strategic, with the eyes being necessarily incorporated into a configural face representation.     

Using the Delphi Technique: Experience from the world of counselling and psychotherapy

Background: Delphi studies have been popular in the health and social care domain for some time, particularly within nursing. They are used to elicit views and opinions from experts in the field on specific topics, without the need for face‐to‐face interviews. Focus: This paper brings Delphi methodology to the attention of potential researchers in the counselling and psychotherapy field, who may not have previously considered Delphi methodology, describing the researcher's experience of using a Delphi study through the media of electronic mail, and incorporating participant feedback. Aims: To discuss the advantages and disadvantages, as well as the complexities and limitations of the Delphi methodology. I will outline previous recommendations from Delphi researchers and offer further suggestions based on my experience of completing a Delphi study.     

4—6岁幼儿图画书自主阅读过程中文字注视的眼动研究

儿童早期的文字意识是儿童阅读能力发展最重要的两个预测变量之一,在幼儿时期表现为对文字的关注。研究以121名4-6岁幼儿为被试,采用TobiiT60眼动仪记录幼儿在图画书阅读过程中对文字注视的眼动。结果发现:1.幼儿在自主阅读情境下仍然首先关注图画、在阅读过程中主要关注图画,自主阅读情境中幼儿对文字的注视时间比例和注视次数比例远高于亲子阅读情境中的比例。2.年龄和文字面积是幼儿图画书自主阅读中文字注视的核心影响因素,幼儿对文字的注视比例随着年龄的增长而不断提高,文字面积通过年龄对幼儿的文字注视起作用。3.幼儿早期阅读能力经历了从图画到文字的发展过程,学前末期,幼儿逐渐成为一个初步的文字阅读者。     

内源性眼跳与注意转移关系研究述评

视觉选择过程中既存在外显的眼跳行为,也包含内隐的注意转移,两者对于视觉目标的加工都有促进作用。近二十年来出现大量关于二者关系的研究,多数研究者发现眼跳和注意转移存在密切联系。内源性眼跳是个体根据目标或意愿主动发起的眼跳,对人类生存具有重大意义。本文系统回顾了视觉加工领域中对于内源性眼跳与空间注意转移关系问题的探讨及其研究成果,分别从行为研究和神经心理学研究两个方面阐述了该领域的研究进展并作出简要评价及展望。     

视觉搜索中非对称性的实验研究

为了解视觉搜索中的非对称性现象以及封闭性这一拓扑特征在前注意加工中的作用,验证Treisman提出的特征整合理论,本实验对Treisma封闭圆开口圆靶子视觉搜索实验进行了改编,对视觉非对称性搜索的加工特征进行了验证研究。结果发现:对封闭圆的搜索时间显著大于开口圆的搜索时间,体现了视觉搜索的非对称性;开口圆的搜索不受开口大小的影响,开口大小对封闭圆视觉搜索时间的影响不明显;无论搜索开口圆还是封闭圆,画面大小都对其反应时有显著的影响,本研究结果证实了前注意加工阶段的存在及靶子和干扰项和互动关系。
