面孔知觉中特征、结构和整体加工策略的眼动研究

考察面孔知觉中特征加工、结构加工和整体加工三种不同加工方式对应的眼动模式。实验1中, 将以特征信息为主的错乱面孔和以结构信息为主的模糊面孔作为线索刺激, 引发对测试面孔的特征加工和结构加工, 眼动分析表明：特征加工表现为对面孔各特征内更长的凝视时间, 结构加工表现为对面孔各特征间高频的眼跳。实验2采用相同的研究范式, 将完整面孔、轻度错乱面孔和低水平模糊面孔作为线索刺激, 引发对测试面孔除特征加工和结构加工外的另一种加工方式-- 整体加工, 表现为注视点更多地落在测试面孔中央区的鼻子部位以扩大注视范围, 进而把握整张面孔信息。本研究揭示了三种不同面孔加工方式眼动模式的差异。     

Effect of racial bias on composite construction

We investigated how prior bias about a face's racial characteristics can affect its encoding and resultant facial composite construction. In total, 61 participants (24 Europeans, 18 Indians living in India and 19 Indians living in Europe) saw a racially ambiguous unfamiliar face and were led to believe it was either European or Indian. They created a composite of this face, using EFIT6. Two groups of independent raters (one Indian, the other European) then assessed the apparent race of each composite. A different two groups (one Indian, one European) assessed each composite's degree of resemblance to the target face, to determine whether this was influenced by the constructors' initial categorisation of the target face as “own-race” or “other-race.” Composites appeared significantly more “Asian” or “European” according to the bias induced in their creators, but there was no evidence of any own-race bias in the resemblance ratings for the composites.     

Mixed matters: fluency impacts trust ratings when faces range on valence but not on motivational implications

Facial features that resemble emotional expressions influence key social evaluations, including trust. Here, we present four experiments testing how the impact of such expressive features is qualified by their processing difficulty. We show that faces with mixed expressive features are relatively devalued, and faces with pure expressive features are relatively valued. This is especially true when participants first engage in a categorisation task that makes processing of mixed expressions difficult and pure expressions easy. Critically, we also demonstrate that the impact of categorisation fluency depends on the specific nature of the expressive features. When faces vary on valence (i.e. sad to happy), trust judgments increase with their positivity, but also depend on fluency. When faces vary on social motivation (i.e. angry to sad), trust judgments increase with their approachability, but remain impervious to disfluency. This suggests that people intelligently use fluency to make judgments on valence-relevant judgment dimensions – but not when faces can be judged using other relevant criteria, such as motivation. Overall, the findings highlight that key social impressions (like trust) are flexibly constructed from inputs related to stimulus features and processing experience.     

Self-efficacy dimensions and job search strategies

ObjectiveThis study explored the paths between dimensions of self-efficacy and job search strategies. An examination of social cognitive career theory and career adaptability enabled us to consider several paths between dimensions of self-efficacy and job search strategies, as well as among self-efficacy dimensions.MethodScales measuring these concepts were administered to a sample of 120 jobseekers.ResultsStructural analyses allowed us to confirm expected paths. Barrier coping efficacy is significantly related to career decision self-efficacy. Career decision self-efficacy and job search self-efficacy are related to exploratory strategy and to job search strategy.ConclusionResults are discussed with reference to the literature and in terms of practical implications. They highlight the need to implement interventions in order to increase barrier coping efficacy and career decision self-efficacy.     

面孔-人格知觉中眼部线索及其效应

人们常常会基于他人面孔特征对其人格做出相应推论。在影响面孔-人格知觉的五官特征中, 眼部特征最具复杂性。总体上, 眼部线索可分为可变和不可变两大类。可变线索包括注视方向、眼睑开放程度与眼部区域的表情等; 不可变线索包括眼睛大小、巩膜着色程度、虹膜颜色以及巩膜暴露指数等。从以上线索效应的潜在作用机制来看, 可以将眼部线索分为三大类, 即受病理因素影响的眼部线索、与特定群体相关的眼部线索和受主观意识或生理因素调控的眼部线索。此外, 也进一步指出了未来研究还需加以考虑的其他眼部特征效应, 以及待拓展深入的研究视角。     

Facial first impressions and partner preference models: Comparable or distinct underlying structures?

Given the frequency of relationships nowadays initiated online, where impressions from face photographs may influence relationship initiation, it is important to understand how facial first impressions might be used in such contexts. We therefore examined the applicability of a leading model of verbally expressed partner preferences to impressions derived from real face images and investigated how the factor structure of first impressions based on potential partner preference-related traits might relate to a more general model of facial first impressions. Participants rated 1,000 everyday face photographs on 12 traits selected to represent (Fletcher, et al. 1999, Journal of Personality and Social Psychology, 76, 72) verbal model of partner preferences. Facial trait judgements showed an underlying structure that largely paralleled the tripartite structure of Fletcher et al.'s verbal preference model, regardless of either face gender or participant gender. Furthermore, there was close correspondence between the verbal partner preference model and a more general tripartite model of facial first impressions derived from a different literature (Sutherland et al., 2013, Cognition, 127, 105), suggesting an underlying correspondence between verbal conceptual models of romantic preferences and more general models of facial first impressions.     

Finding an unfamiliar face in a line-up: Viewing multiple images of the target is beneficial on target-present trials but costly on target-absent trials

When viewing unfamiliar faces, photographs of the same person often are perceived as belonging to different people and photographs of different people as belonging to the same person. Identity matching of unfamiliar faces is especially challenging when the photographs are of a person whose ethnicity differs from that of the observer. In contrast, matching is trivial when viewing familiar faces, regardless of race. Viewing multiple images of an own-race target identity improves accuracy on a line-up task when the target is known to be present (Dowsett et al., 2016, Q J Exp Psychol, 69, 1), suggesting that exposure to within-person variability in appearance is key to face learning. Across three experiments, we show that viewing multiple images of a target identity also improves accuracy for other-race faces on target-present trials. However, viewing multiple images decreases accuracy (i.e., increases false alarms) on target-absent trials for both own- and other-race faces. We discuss the implications of our findings for models of face recognition and for forensic settings.     

Investigating the other-race effect in working memory

People have difficulties in remembering other-race faces; this so-called other-race effect (ORE) has been frequently observed in long-term recognition memory (LTM). Several theories argue that the ORE in LTM is caused by differences in earlier processing stages, such as encoding of ingroup and outgroup faces. We test this hypothesis by exploring whether the ORE can already be observed in visual working memory (VWM)—an intermediate system located between encoding processes and LTM storage. In four independent experiments, we observed decreased performance for outgroup faces compared to ingroup faces using three different VWM tasks: an adaptive N-back task, a self-ordered pointing task, and a change detection task. Also, we found that the number of items stored in VWM is smaller for outgroup faces than for ingroup faces. Further, we explored whether performance differences in the change detection task are related to the classic ORE in recognition memory. Our results provide further evidence that the ORE originates during earlier stages of cognitive processing. We discuss that (how) future ORE research may benefit from considering theories and evidence from the VWM literature.

Familiarity matters: A review on prioritized processing of personally familiar faces

In this review, we synthesize the existing literature investigating personally familiar face processing and highlight the remarkable, enhanced processing efficiency resulting from real-life experience. Highly learned identity-specific visual and semantic information associated with personally familiar face representations facilitates detection, recognition of identity and social cues, and activation of person knowledge. These optimizations afford qualitatively different processing of personally familiar as compared to unfamiliar faces, which manifests on both the behavioural and neural level.
