Holistic processing predicts face recognition

The concept of holistic processing is a cornerstone of face-recognition research. In the study reported here, we demonstrated that holistic processing predicts face-recognition abilities on the Cambridge Face Memory Test and on a perceptual face-identification task. Our findings validate a large body of work that relies on the assumption that holistic processing is related to face recognition. These findings also reconcile the study of face recognition with the perceptual-expertise work it inspired; such work links holistic processing of objects with people's ability to individuate them. Our results differ from those of a recent study showing no link between holistic processing and face recognition. This discrepancy can be attributed to the use in prior research of a popular but flawed measure of holistic processing. Our findings salvage the central role of holistic processing in face recognition and cast doubt on a subset of the face-perception literature that relies on a problematic measure of holistic processing.

加工焦点性和任务负荷对不同认知方式大学生前瞻记忆的影响

采用双任务范式,探讨了加工焦点性和进行中任务负荷对不同认知方式大学生前瞻记忆的影响。包括两个实验:实验一探讨进行中任务与前瞻记忆任务加工的焦点性和加工类型的一致性对不同认知方式大学生前瞻记忆的影响;实验二探讨进行中任务负荷对不同认知方式大学生在在焦点加工和非焦点加工条件下前瞻记忆的影响。结果显示:焦点加工条件下的前瞻记忆成绩高于非焦点加工,且不受进行中任务负荷的影响;不管进行中任务与前瞻记忆任务的加工类型是否一致,在进行中任务负荷较高且非焦点加工条件下,场独立大学生的前瞻记忆成绩高于场依存大学生。本研究结果支持多重加工理论。     

不同加工类型的不同加工水平对内隐记忆的影响的研究

针对加工水平对内隐记忆的影响的研究结论互相矛盾的现状．本研究认为有三个方面的原因。通过实验和讨论得出如下结论：1、加工类型和加工水平是对加工在质与量上分别作出的区分,这种区分与有意识／无意识在学习加工中的引入是有意义和必要的。2、内隐记忆存在着加工水平效应。这个结论支持和补充了加工的观点。3、概念驱动测验和数据驱动测验都受到了语义和非语义变量的影响。

Rapid communication: Global-local processing affects recognition of distractor emotional faces

Recent studies have shown links between happy faces and global, distributed attention as well as sad faces to local, focused attention. Emotions have been shown to affect global-local processing. Given that studies on emotion-cognition interactions have not explored the effect of perceptual processing at different spatial scales on processing stimuli with emotional content, the present study investigated the link between perceptual focus and emotional processing. The study investigated the effects of global-local processing on the recognition of distractor faces with emotional expressions. Participants performed a digit discrimination task with digits at either the global level or the local level presented against a distractor face (happy or sad) as background. The results showed that global processing associated with broad scope of attention facilitates recognition of happy faces, and local processing associated with narrow scope of attention facilitates recognition of sad faces. The novel results of the study provide conclusive evidence for emotion-cognition interactions by demonstrating the effect of perceptual processing on emotional faces. The results along with earlier complementary results on the effect of emotion on global-local processing support a reciprocal relationship between emotional processing and global-local processing. Distractor processing with emotional information also has implications for theories of selective attention.     

Asymmetric interference between domains: evidence from the stimulus order effect in complex span tasks

The stimulus order effect refers to the finding that recall in complex span tasks is better when span lists begin with a longer processing task and end with a shorter task than when these processing tasks are presented in the reverse order. This study independently manipulated processing time and processing difficulty between Long-final and Short-final lists. The processing task required participants to solve arithmetic problems with either verbal (Experiment 1) or visuospatial (Experiment 2) materials. The memory items used in the storage task were either digits (verbal material) or dots-in-matrices (visuospatial materials). Storage of both verbal and visuospatial materials was sensitive to the change in processing difficulty, but not processing time. Furthermore, this study provides further evidence for the asymmetry of domain interference in working memory. The similarities and differences between verbal and visuospatial storage in working memory are discussed.     

The effect of midazolam on implicit and explicit memory in category exemplar production and category cued recall

Transfer-appropriate processing theory (Roediger, Weldon, & Challis, 1989) proposes that dissociations between performance on explicit and implicit memory tests arise because these tests often rely on different types of information processing (e.g., perceptual processing vs conceptual processing). This perspective predicts that implicit and explicit memory tasks that rely primarily on conceptual processing should show comparable results, not dissociations. Numerous studies have demonstrated such similarities. It is, however, possible that these results arise from explicit memory contamination of performance on implicit memory tasks. To address this issue, an experiment was conducted in which participants were administered the sedative midazolam prior to study. Midazolam is known to create a temporary, but dense, period of anterograde amnesia. The effects of blocking stimulus materials by semantic category at study and generation at study were investigated on category exemplar production and category-cued recall. The results of this study demonstrated a dissociation of the effects of midazolam on category exemplar production and category-cued recall. Specifically, midazolam reduced the effect of blocking stimulus materials in category-cued recall, but not in category exemplar production. The differential effect of midazolam on explicit and implicit memory is at odds with transfer-appropriate processing theory and suggests that theories of memory must distinguish the roles of different types of conceptual processing on implicit and explicit memory tests.     

语义透明度和构词频率对汉语动词多词素词识别的影响*

采用重复启动范式,通过两个实验,考察语义透明度和词素构词频率对动词多词素词识别的影响。结果发现：（1）语义透明度影响多词素动词的识别,识别高语义透明度的动词快于识别低语义透明度的动词。（2）词素的构词频率影响低语义透明度动词的识别,不影响高语义透明度动词的识别。对低语义透明动词,词素的构词频率低的动词的反应时显著短于词素的构词频率高的动词。研究结果支持汉语多词素词的多层次双系统选择加工模型。     

汉字加工中呈现速率对重复知盲效应的影响

实验采用RSVP任务,考察了汉字加工中呈现速率对重复知盲效应的影响,结果发现：（1）在加工汉字重复刺激时,存在着重复知肓（RB）效应,其强度随着呈现速率的变化而改变,当呈现速率较快时,正确率较低,呈现速率较慢时,正确率较高;（2）与加工英文信息比较,在汉字加工中,RB效应的出现似乎推迟了一段时间,这可能从另一方面反映出加工汉字比英文需要不同的加工时间．即加工信息的难易程度也影响RB效应出现的时间。     

The effect of midazolam on implicit and explicit memory in category exemplar production and category cued recall

Transfer‐appropriate processing theory (Roediger, Weldon, & Challis, 1989) proposes that dissociations between performance on explicit and implicit memory tests arise because these tests often rely on different types of information processing (e.g., perceptual processing vs conceptual processing). This perspective predicts that implicit and explicit memory tasks that rely primarily on conceptual processing should show comparable results, not dissociations. Numerous studies have demonstrated such similarities. It is, however, possible that these results arise from explicit memory contamination of performance on implicit memory tasks. To address this issue, an experiment was conducted in which participants were administered the sedative midazolam prior to study.

The results of this study demonstrated a dissociation of the effects of midazolam on category exemplar production and category‐cued recall. Specifically, midazolam reduced the effect of blocking stimulus materials in category‐cued recall, but not in category exemplar production. The differential effect of midazolam on explicit and implicit memory is at odds with transfer‐appropriate processing theory and suggests that theories of memory must distinguish the roles of different types of conceptual processing on implicit and explicit memory tests.     

Word‐of‐mouth information processing routes: The mediating role of message and source characteristics

This study investigates word‐of‐mouth (WOM) information processing routes from active WOM seeking behaviour. Employing the elaboration likelihood model (ELM), the direct and indirect effects of factors within information processing routes are examined in a credence service context. A deeper exploration of the causal chains of each route was conducted using serial mediation models of message quality and source characteristics. Data were collected in the higher education context from a survey of 509 high school students applying for tertiary study. Findings indicate that active WOM seeking and the serial mediation effects elicit two routes of information processing: central and peripheral. This study is amongst the first to intensively reveal the underlying causal chains of WOM processing and supports the application of ELM theory in WOM research.     

Syntactic processing in bilinguals: an fNIRS study

The study of the neural basis of syntactic processing has greatly benefited from neuroimaging techniques. Research on syntactic processing in bilinguals has used a variety of techniques, including mainly functional magnetic resonance imaging (fMRI) and event-related potentials (ERP). This paper reports on a functional near-infrared spectroscopy (fNIRS) study on syntactic processing in highly proficient young adult speakers of Portuguese (mother tongue) (L1) and French (second language) (L2). They made a syntactic judgment of visually presented sentences, which either did or did not contain noun-verb agreement violations. The results showed that syntactic processing in both languages resulted in significant activation in anterior frontal regions of the left hemisphere and in the temporal superior posterior areas of the right hemisphere, with a more prominent activation for L2 in some areas. These findings corroborate previously reported neuroimaging evidence, showing the suitability of fNIRS for the study of syntactic processing in the bilingual brain.     

Adaptive Memory: Identifying the Proximate Roots of the Survival Processing Advantage

The current study examined the role of item-specific, relational, and elaborative processing on adaptive memory. Younger and older adults received the standard survival processing, a survival-short, or a pleasantness processing instruction. The survival-short condition was specifically included to lead to fewer possibilities to engage in elaborative processing. Furthermore, half of the presented words were categorized words to boost relational processing. Younger adults demonstrated the typical survival recall advantage in that standard survival processing instructions resulted in superior free recall performance than that of the survival-short and the pleasantness processing groups. Among older adults, no mnemonic benefit of standard survival processing relative to the survival-short or pleasantness processing groups was found. Furthermore, reducing the probability of elaborative processing (i.e., through the survival-short processing instructions) abolished the survival recall advantage. Our results thus provide further evidence for the role of item-specific, relational, and elaborative processing in the survival processing advantage.

加工流畅性对学习判断字体大小效应的影响

以自定步调学习时间和习得试验次数为加工流畅性指标,通过操纵不同字号的词对考察了加工流畅性对学习判断字体大小效应的影响。结果发现：（1）字体大小影响学习判断,但不影响回忆成绩;（2）不同字体大小的词对在加工流畅性（学习时间和学习次数）上存在差异,仅自定步调学习时间测量的加工流畅性对学习判断字体大小效应有贡献。这些结果说明学习判断的字体大小效应是一种元认知错觉现象,部分支持了加工流畅性假说。     

一致性、相关性对记忆生存优势效应的影响

对词语进行生存加工能提高记忆成绩,这种记忆的生存优势效应已得到不少研究的验证,且大多数研究表明生存优势是一种独特的编码方式(Nairne&Pandeirada,2011)。但是,Butler等人(2009)的研究结果表明实验中生存加工带来的记忆优势可能是一致性效应(即编码任务与编码的材料之间具有一致性)的作用。本文在2个实验中选用与生存和抢劫加工条件相关程度不同的词(高中低)为实验材料,采用生存加工、抢劫加工、愉悦度和有意学习为实验条件,研究一致性和相关性在记忆生存优势中的作用。结果发现:(1)生存条件下的记忆效果显著优于愉悦度条件和有意学习条件,这说明的确存在记忆的生存优势效应;(2)高生存相关词在生存加工条件下产生了记忆优势,而中、低生存相关词在2种加工条件下记忆成绩差异不显著,这说明加工条件的一致性只在一定程度上影响着记忆的生存优势效应;(3)词语自身的生存相关性没有表现出较强的记忆优势,当然这也可能与实验材料的词频有关。研究结果支持了Nairne和Pandeirada(2011)的观点。     

关于RB效应加工水平的研究

本研究采用正字法相似的汉字作为实验材料考察了RSVP任务中的RB效应的加工水平。研究发现：(1)RB效应不仅出现在重复字中,而且也出现在正字法相似字中,但其强度弱于重复字中的RB效应;(!)在正字法相似的汉字加工中．由于加工相似字的识别错误发生在语义加工之前的阶段．因此．RB效应的产生点可能出现在记忆加工之前的知觉阶段。     

Local and global cross-modal influences between vision and hearing, tasting, smelling, or touching

It is suggested that the distinction between global versus local processing styles exists across sensory modalities. Activation of one-way of processing in one modality should affect processing styles in a different modality. In 12 studies, auditory, haptic, gustatory or olfactory global versus local processing was induced, and participants were tested with a measure of their global versus local visual attention; the content of this measure was unrelated to the inductions. In a different set of 4 studies, the effect of local versus global visual processing on the way people listen to a poem or touch, taste, and smell objects was examined. In all experiments, global/local processing in 1 modality shifted to global/local processing in the other modality. A final study found more pronounced shifts when compatible processing styles were induced in 2 rather than 1 modality. Moreover, the study explored mediation by relative right versus left hemisphere activation as measured with the line bisection task and accessibility of semantic associations. It is concluded that the effects reflect procedural rather than semantic priming effects that occurred out of participants' awareness. Because global/local processing has been shown to affect higher order processing, future research may activate processing styles in other sensory modalities to produce similar effects. Furthermore, because global/local processing is triggered by a variety of real world variables, one may explore effects on other sensory modalities than vision. The results are consistent with the global versus local processing model, a systems account (GLOMOsys; F?rster & Dannenberg, 2010).
