面孔吸引力同化的连续性效应

以往研究表明目标面孔的吸引力评价会偏向背景面孔, 产生同化效应。但同化效应的计算常常是对不同背景下目标面孔吸引力评分进行比较, 并没有考虑目标面孔单独呈现时的吸引力评分, 可能是虚假的同化效应。本文以单独呈现的目标面孔吸引力评分作为基准值计算同化效应, 考察了呈现时间和目标与背景面孔吸引力的差异对目标面孔吸引力评价的影响。结果发现, 个体对目标面孔吸引力的评分会偏向背景面孔的吸引力, 并表现出同化的连续性效应, 即目标和背景面孔的吸引力差异越大, 同化效应越小。     

The influence of position and context on facial attractiveness

It has been shown that a person's position in a group influences how that person is evaluated, with people in the middle perceived as more important than people on the fringe of a group. Four experiments examined whether the position of a face, in a line of five faces, influenced facial attractiveness. The middle position influenced the perceived attractiveness of the target face but the direction of this effect depended on the attractiveness of the target and the surrounding faces. Attractive faces were perceived as less attractive when in the middle of unattractive faces, or faces of average attractiveness. Conversely, unattractive faces were perceived as more attractive when in the middle of other unattractive faces. These results have wide implications, suggesting that the more central a stimulus is in a context then the greater the influence of the context on the judgment of that stimulus.     

The influence of flankers on race categorization of faces

Context affects multiple cognitive and perceptual processes. In the present study, we asked how the context of a set of faces would affect the perception of a target face??s race in two distinct tasks. In Experiments 1 and 2, participants categorized target faces according to perceived racial category (Black or White). In Experiment 1, the target face was presented alone or with Black or White flanker faces. The orientation of flanker faces was also manipulated to investigate how face inversion effect would interact with the influences of flanker faces on the target face. The results showed that participants were more likely to categorize the target face as White when it was surrounded by inverted White faces (an assimilation effect). Experiment 2 further examined how different aspects of the visual context would affect the perception of the target face by manipulating flanker faces?? shape and pigmentation, as well as their orientation. The results showed that flanker faces?? shape and pigmentation affected the perception of the target face differently. While shape elicited a contrast effect, pigmentation appeared to be assimilative. These novel findings suggest that the perceived race of a face is modulated by the appearance of other faces and their distinct shape and pigmentation properties. However, the contrast and assimilation effects elicited by flanker faces?? shape and pigmentation may be specific to race categorization, since the same stimuli used in a delayed matching task (Experiment 3) revealed that flanker pigmentation induced a contrast effect on the perception of target pigmentation.     

The cheerleader effect is robust to experimental manipulations of presentation time

ABSTRACT

The “cheerleader effect” occurs when the same face is perceived to be significantly more attractive when seen among a group of faces compared to alone. Since perceived attractiveness decreases with additional viewing time, we investigated whether the cheerleader effect occurs simply because the target face is seen for less time in a group than it is alone. Observers rated the attractiveness of each target face twice; once in a group, and once alone. We manipulated the amount of time that each group image was presented for prior to the cue toward the target face (300, 1000, 2000, 3000, or 7000 milliseconds). Faces were perceived to be significantly more attractive in each group condition, regardless of presentation time, replicating the cheerleader effect. Furthermore, uncued presentation time did not modulate the magnitude of this increase, demonstrating that a presentation time discrepancy does not contribute to the size of the typical cheerleader effect.     

A formal analysis of ratings of physical attractiveness: Successive contrast and simultaneous assimilation

Photographs of faces were presented in a series, either singly or in pairs, for ratings of physical attractiveness. In Experiment 1, faces were presented singly, and both the range and relative frequencies of physical attractiveness (on baseline scaling) were manipulated experimentally. The same face elicited higher ratings when less attractive faces predominated in the experimental series, successive contrast. Increasing the number of available categories resulted in higher ratings but did not reduce the amount of successive contrast. Both range and skewing effects were in accordance with a range-frequency model that permits the subjective range to vary with number of categories. In Experiment 2, faces were presented in pairs. The same face now elicited lower ratings when presented simultaneously with a less attractive face, simultaneous assimilation. Successive contrast was again observed between pairs and was greater for 5- than for 101-point rating scales. A model that uses the judgments resulting from a range-frequency compromise as the stimulus values for integration within pairs provides the best account of how both contrast and assimilation occur within the same experimental session. Alternative interpretations of the observed contrast and assimilation were discussed.     

基于合成平均刺激的平均表征机制——来自平均面孔吸引力的证据

人类能够快速提取集合中的统计信息, 形成平均表征。对于平均表征的产生机制, 研究者提出整合集合成员以合成平均刺激, 或计算集合成员特征值的平均值两种观点。以往研究中合成的平均刺激的特征值和计算成员特征值的平均值两种方式的结果相似, 难以区分两种观点。由于多个面孔的吸引力评分的均值与用这些面孔合成的平均面孔的吸引力评分存在差异, 本研究使用经典的平均辨别任务(实验1和2)和吸引力评价任务(实验3和4)为平均表征的产生来源于合成平均刺激的观点提供了支持证据。4个实验分别采用大容量面孔集合和小容量面孔集合探讨平均表征的形成机制, 结果发现大、小集合都形成了平均刺激, 并且平均表征的评定和加工可能更多依赖合成的平均刺激, 而非简单的对成员特征值进行平均; 此外, 集合吸引力出现了高评现象, 但小集合高评现象更少出现, 说明平均刺激的作用受到集合大小的影响。本研究为集合平均表征的形成机制和面孔集合吸引力高评现象的产生机制提供了新证据。

采用图像处理技术和眼动探讨了性别二态线索对面孔偏好的影响。实验1发现非面孔线索未掩蔽和掩蔽时, 感知男性化技术与原始照片条件下女性化的男性面孔更有吸引力和信任度; 性别二态技术条件下, 非面孔线索未掩蔽时男性化的男性面孔更有吸引力和信任度。实验2表明被试对男性面孔的平均瞳孔大小和注视次数均大于和多于女性面孔, 首次注视时间短于女性面孔; 被试对男性化面孔的首次注视时间和首次注视持续时间均长于女性化面孔。     

Computer graphic studies of the role of facial similarity in judgements of attractiveness

Anecdotally, spouses are often said to resemble one another. This study investigates the effects of similarity between participants and stimuli on judgements of facial attractiveness: does “like prefer like”? Using computer graphic techniques, opposite sex facial stimuli were generated from subjects' photographs. Experiment 1 showed a correlation between attractiveness and similarity but the effect can be explained by the attractiveness of average faces. Beyond this, there was a trend for individual subjects to rate opposite sex images with a similar face shape to their own face as more attractive than other subjects. Experiment 2 allowed subjects to interactively manipulate an opposite sex facial image along a continuum from a self-similar shape, through an average face shape, to a face with opposite characteristics. No significant preferences for self-similar or opposite characteristics were found. Preferences for average faces are stronger than preferences for self-similar faces.

How facial attractiveness affects sustained attention

The present study investigated whether and how facial attractiveness affects sustained attention. We adopted a multiple‐identity tracking paradigm, using attractive and unattractive faces as stimuli. Participants were required to track moving target faces amid distractor faces and report the final location of each target. In Experiment 1, the attractive and unattractive faces differed in both the low‐level properties (i.e., luminance, contrast, and color saturation) and high‐level properties (i.e., physical beauty and age). The results showed that the attractiveness of both the target and distractor faces affected the tracking performance: The attractive target faces were tracked better than the unattractive target faces; when the targets and distractors were both unattractive male faces, the tracking performance was poorer than when they were of different attractiveness. In Experiment 2, the low‐level properties of the facial images were equalized. The results showed that the attractive target faces were still tracked better than unattractive targets while the effects related to distractor attractiveness ceased to exist. Taken together, the results indicate that during attentional tracking the high‐level properties related to the attractiveness of the target faces can be automatically processed, and then they can facilitate the sustained attention on the attractive targets, either with or without the supplement of low‐level properties. On the other hand, only low‐level properties of the distractor faces can be processed. When the distractors share similar low‐level properties with the targets, they can be grouped together, so that it would be more difficult to sustain attention on the individual targets.     

Similarity modulates the face-capturing effect in change detection

We investigated whether similarity among faces could modulate the face-capturing effect in change detection. In Experiment 1, a singleton search task was used to demonstrate that a face stimulus captures attention and the odd-one-out hypothesis cannot account for the results. Searching for a face target was faster than searching for a nonface target no matter whether distractor–distractor similarity was low or high. The fast search, however, did not lead to a face-detection advantage in Experiment 2 when the pre- and postchange faces were highly similar. When participants in Experiment 3 had to divide their attention between two faces in stimulus displays for change detection, detection performance was worse than performance in detecting nonface changes. The face-capturing effect alone is insufficient to produce the face-detection advantage. Face processing is efficient but its effect on performance depends on the stimulus–task context.     

Preadolescents' recognition of faces of unfamiliar peers: the effect of attractiveness of faces

The authors examined preadolescents' ability to recognize faces of unfamiliar peers according to their attractiveness. They hypothesized that highly attractive faces would be less accurately recognized than moderately attractive faces because the former are more typical. In Experiment 1, 106 participants (M age = 10 years) were asked to recognize faces of unknown peers who varied in gender and attractiveness (high- vs. medium-attractiveness). Results showed that attractiveness enhanced the accuracy of recognition for boys' faces and impaired recognition of girls' faces. The same interaction was found in Experiment 2, in which 92 participants (M age = 12 years) were tested for their recognition of another set of faces of unfamiliar peers. The authors conducted Experiment 3 to examine whether the reason for that interaction is that high- and medium-attractive girls' faces differ more in typicality than do boys' faces. The effect size of attractiveness on typicality was similar for boys' and girls' faces. The overall results are discussed with reference to the development of face encoding and biological gender differences with respect to the typicality of faces during preadolescence.     

Facial symmetry and the perception of beauty

Evolutionary, as well as cultural, pressures may contribute to our perceptions of facial attractiveness. Biologists predict that facial symmetry should be attractive, because it may signal mate quality. We tested the prediction that facial symmetry is attractive by manipulating the symmetry of individual faces and observing the effect on attractiveness, and by examining whether natural variations in symmetry (between faces) correlated with perceived attractiveness. Attractiveness increased when we increased symmetry, and decreased when we reduced symmetry, in individual faces (Experiment 1), and natural variations in symmetry correlated significantly with attractiveness (Experiments 1 and 1A). Perfectly symmetric versions, made by blending the normal and mirror images of each face, were preferred to less symmetric versions of the same faces (even when those versions were also blends) (Experiments 1 and 2). Similar results were found when subjects judged the faces on appeal as a potential life partner, suggesting that facial symmetry may affect human mate choice. We conclude that facial symmetry is attractive and discuss the possibility that this preference for symmetry may be biologically based.     

Something to smile about: The interrelationship between attractiveness and emotional expression

Previous studies have suggested a link between the processing of the emotional expression of a face and how attractive it appears. In two experiments we investigated the interrelationship between attractiveness and happiness. In Experiment 1 we presented morphed faces varying in attractiveness and happiness and asked participants to choose the more attractive of two simultaneously presented faces. In the second experiment we used the same stimuli as in Experiment 1 and asked participants to choose the happier face. The results of Experiment 1 revealed that the evaluation of attractiveness is strongly influenced by the intensity of a smile expressed on a face: A happy facial expression could even compensate for relative unattractiveness. Conversely, the findings of Experiment 2 showed that facial attractiveness also influences the evaluation of happiness: It was easier to choose the happier of two faces if the happier face was also more attractive. We discuss the interrelationship of happiness and attractiveness with regard to evolutionary relevance of positive affective status and rewarding effects.

The combined effect of gaze direction and facial expression on cueing spatial attention

Empirical evidence shows an effect of gaze direction on cueing spatial attention, regardless of the emotional expression shown by a face, whereas a combined effect of gaze direction and facial expression has been observed on individuals' evaluative judgments. In 2 experiments, the authors investigated whether gaze direction and facial expression affect spatial attention depending upon the presence of an evaluative goal. Disgusted, fearful, happy, or neutral faces gazing left or right were followed by positive or negative target words presented either at the spatial location looked at by the face or at the opposite spatial location. Participants responded to target words based on affective valence (i.e., positive/negative) in Experiment 1 and on letter case (lowercase/uppercase) in Experiment 2. Results showed that participants responded much faster to targets presented at the spatial location looked at by disgusted or fearful faces but only in Experiment 1, when an evaluative task was used. The present findings clearly show that negative facial expressions enhance the attentional shifts due to eye-gaze direction, provided that there was an explicit evaluative goal present.     

Is positivity a cue or a response option? Warm glow vs evaluative matching in the familiarity for attractive and not-so-attractive faces

Monin (2003) showed that the attractiveness of a face increases its perceived familiarity regardless of prior exposure, and suggested that this beautiful-is-familiar effect was due to the misattribution to familiarity of the positive affect (or “warm glow”) elicited by attractive faces. This research tests the alternative interpretation that an evaluative match between a positive stimulus (an attractive face) and a positive response (“familiar”) accounts for this effect in the absence of any misattribution. In a face recognition task, participants were led to signal their sense of familiarity with previously seen and unseen faces by selecting either a pleasant (affectively congruent) or unpleasant (affectively incongruent) image. Consistent with the warm glow heuristic, higher false alarm rates were obtained for more attractive distracters, and this effect survived (and was, if anything, stronger) when an affectively incongruent response format was used. These findings are discussed in the context of current face memory and perceptual fluency models.     

Sequential effects in face-attractiveness judgment

A number of studies have shown that current-trial responses are biased toward the response of the preceding trial in perceptual decisionmaking tasks (the sequential effect-Holland and Lockhead, 1968 Perception & Psychophysics 3 409-414). The sequential effect has been widely observed in evaluation of the physical properties of stimuli as well as more complex properties. However, it is unclear whether subjective decisions (e.g., attractiveness judgments) are also susceptible to the sequential effect. Here, we examined whether the sequential effect would occur in face-attractiveness judgments. Forty-eight pictures of male and female faces were presented successively. Participants rated the attractiveness of each face on a 7-point scale. The results showed that the attractiveness rating of a given face assimilated toward the rating of the preceding trial. In a separate experiment, we provided the average attractiveness rating by others for each trial as feedback. The feedback weakened the sequential effect. These findings suggest that attractiveness judgment is also biased toward the preceding judgment, and hence the sequential effect can be extended into the domain of subjective decisionmaking.
