不同任务情境中5~6岁儿童卡通面孔加工的眼动研究

以卡通面孔图片为刺激材料,赋予5~6岁儿童三种不同的加工任务,包括卡通面孔识别、分类和吸引力评价,旨在比较其在不同任务情境中的眼动差异。结果表明:(1)任务情境会影响儿童对卡通面孔的加工。在不同的面孔加工任务中,儿童的反应时、正确率、注视时间和次数等存在差异;(2)随着三种任务难度的逐渐加大,儿童的加工程度也相应地加深;(3)儿童在三种任务中的加工方式一致,对面部不同部位的关注程度不同:加工初期特别关注鼻子,而后眼睛部位耗费最多的注意资源,其次是鼻子、嘴巴、前额和脸颊,极少关注下巴;(4)男女童在卡通面孔分类任务中表现出较显著的性别差异,女童具有速度方面的优势,而男童对于关键信息的搜索则更为积极主动。     

面孔相似性判断中各部件的权重分配

采用多级估量法,通过分析不同隶属度的部件样例组合成的面孔样例对原型的隶属度,考察耳朵、脸型、眼睛和嘴巴等部件在面孔相似性判断中的作用。结果发现,面孔相似性判断中,人们对不同面孔部件赋予的权重并不相同,对脸型和嘴巴赋予的权重较大,而对耳朵和眼睛赋予的权重较小。表明,面孔各部件在面孔相似性判断中的作用不同,相对于耳朵和眼睛,脸型和嘴巴的作用更大;面孔内部特征和外部特征的划分方法并不一定适合于面孔相似性判断。     

自我信息加工优势中的熟悉性问题

熟悉性对于自我信息加工优势的影响往往与自我相关性的作用交织在一起,从而使其成为该领域的一个研究重点和难点。文章分别介绍了自我参照效应、自我面孔和人名识别研究中对该问题进行考察的主要思路与发现。现有证据显示,熟悉性与自我特异性在自我信息的加工优势中是可分离的,从而表明自我信息所固有的高熟悉性可能并不是造成其具有加工优势的决定性因素。文章在展望部分将熟悉性进一步细分为材料的熟悉性与任务的熟悉性,并提出未来的研究应该特别注意考察任务熟悉性可能存在的影响作用。     

Impact of retailer image on private brand attitude: Halo effect and summary construct

The purpose of this article is to examine the influence of retailer image on consumers' attitude towards private brand. More specifically, we evaluate two alternative perspectives of retailer image—the halo effect and the summary construct—and include a moderator variable, consumer familiarity with a retailer's private label products, to discern which of the two models has better explanatory power. The findings indicate that there are moderating effects of consumer familiarity with a retailer's private brands and product categories in determining the efficacy of each model. In private brand foods, high familiarity is related to the summary construct model, and low familiarity is associated with the halo effect model. In private brand clothing, however, low familiarity is related to the halo effect model, but high familiarity is associated with both the halo effect and the summary construct model. Managerial and future research implications are also provided.     

The Role of Recollection and Familiarity in Nondemented Parkinson's Patients

The aim of the current study was to examine if recollection and familiarity decline in nondemented Parkinson's patients. To do so we compared a sample of older people with Parkinson's disease (n = 32) to a control sample of healthy older people (n = 32) on an associative recognition task in which we manipulated the repetition of the pairs during the study phase (half of the pairs were presented once and half twice) to obtain corrected estimates of recollection, familiarity, and false recognition based on the logic of the process-dissociation procedure. The results clearly show that recollection is impaired but familiarity is preserved in nondemented Parkinson's patients. The results show that memory for pairs in Parkinson's patients relies largely on the familiarity of each item and not on a precise recollection of associative information, supporting the idea that recollection-based monitoring processes are impaired in these patients.     

Differential emotion attribution to neutral faces of own and other races

Past research has demonstrated differential recognition of emotion on faces of different races. This paper reports the first study to explore differential emotion attribution to neutral faces of different races. Chinese and Caucasian adults viewed a series of Chinese and Caucasian neutral faces and judged their outward facial expression: neutral, positive, or negative. The results showed that both Chinese and Caucasian viewers perceived more Chinese faces than Caucasian faces as neutral. Nevertheless, Chinese viewers attributed positive emotion to Caucasian faces more than to Chinese faces, whereas Caucasian viewers attributed negative emotion to Caucasian faces more than to Chinese faces. Moreover, Chinese viewers attributed negative and neutral emotion to the faces of both races without significant difference in frequency, whereas Caucasian viewers mostly attributed neutral emotion to the faces. These differences between Chinese and Caucasian viewers may be due to differential visual experience, culture, racial stereotype, or expectation of the experiment. We also used eye tracking among the Chinese participants to explore the relationship between face-processing strategy and emotion attribution to neutral faces. The results showed that the interaction between emotion attribution and face race was significant on face-processing strategy, such as fixation proportion on eyes and saccade amplitude. Additionally, pupil size during processing Caucasian faces was larger than during processing Chinese faces.     

影响动作图片命名的因素

图片是研究词汇习得与加工的重要材料, 而名词和动词是最主要的两类实词。然而, 目前较少有研究考察汉语中的动词加工过程, 也没有标准化的动词图片库。本研究通过成人图片命名和评定任务, 获得了265张动词图片的中文名称、命名反应时, 以及H值、命名一致性、熟悉性、视觉复杂性、表象一致性和口语习得年龄等指标, 同时也探索了影响动作图片命名反应时的因素。逐步回归分析结果发现, H值、熟悉性和视觉复杂性这三个变量可解释动词图片命名反应时72.4%的变异。此外, 本研究根据图片命名反应时将动词图片加工难度分成了五个等级。研究发现, 与名词图片相比, 动词图片的视觉复杂性更高、命名一致性更低、命名反应时更长。本研究获得的各项心理语言学指标有望为后续关于动词加工的实验研究提供重要的参考资料。     

基于熟悉性的项目间语义关系再认

在项目间语义关系的熟悉性研究中, 一个关键问题是熟悉性效应依赖于哪种信息的加工, 关系概念还是抽象结构?研究通过两个实验, 借助无线索回忆再认范式(the recognition without cued recall paradigm, 简称RWCR范式)和四词类比材料, 采用混合设计, 直接分离与比较关系概念和抽象结构的加工对RWCR效应的影响。结果发现, 关系概念作为测验线索能够引发显著RWCR效应, 但仅仅学习关系概念却不能;只有学习关系概念的结构化材料时, 才能引发显著RWCR效应。该结果表明, 项目间语义关系的熟悉性过程与结构信息有关。     

幼儿对假装游戏中意图和行为作用的理解

关于儿童如何理解假装存在两种观点:一种观点认为幼儿能够从心理角度理解假装。另一种观点认为,幼儿只能从假装行为角度理解假装。本研究通过自制录像,考查了3～5岁幼儿对假装游戏中意图和行为作用的理解。实验中,给幼儿呈现3种不同类型的录像情境:有意图-有行为、有意图-无行为和无意图-有行为,要求幼儿回答录像中的主人公是否在假装。实验结果表明,随着幼儿年龄的增长,在录像中主人公明确表达其假装意图的情境下,幼儿能够从心理层面理解假装,并且3～4岁幼儿存在一个快速发展期;同时,假装实体的熟悉度可能影响幼儿对假装的理解。     

Learning unfamiliar faces in infants: The advantage of the regular sequence presentation and the three‐quarter view superiority

We investigated the effect of the regular sequence of different views and the three‐quarter view effect on the learning of unfamiliar faces by infants. 3–8‐month‐old infants were familiarized with unfamiliar female faces in either the regular condition (presenting 11 different face views from the frontal view to the left‐side profile view in regular order) or the random condition (presenting the same 11 different face views in random order). Following the familiarization, infants were tested with a pair of a familiarized and a novel female face either in a three‐quarter (Experiment 1) or in a profile view (Experiment 2). Results showed that only 6–8‐month‐old infants could identify a familiarized face in the regular condition when they were tested in three‐quarter views. In contrast, 6–8‐month‐old infants showed no significant novelty preference in profile views. The results suggest that the regular sequence of different face views promotes the learning of unfamiliar faces by infants over 6 months old. Moreover, our findings imply that the three‐quarter view effect appears in infants.
