Is face distinctiveness gender based?

Two experiments were carried out to study the role of gender category in evaluations of face distinctiveness. In Experiment 1, participants had to evaluate the distinctiveness and the femininity-masculinity of real or artificial composite faces. The composite faces were created by blending either faces of the same gender (sexed composite faces, approximating the sexed prototypes) or faces of both genders (nonsexed composite faces, approximating the face prototype). The results show that the distinctiveness ratings decreased as the number of blended faces increased. Distinctiveness and gender ratings did not covary for real faces or sexed composite faces, but they did vary for nonsexed composite faces. In Experiment 2, participants were asked to state which of two composite faces, one sexed and one nonsexed, was more distinctive. Sexed composite faces were selected less often. The results are interpreted as indicating that distinctiveness is based on sexed prototypes. Implications for face recognition models are discussed.     

Does face familiarity influence speechreadability?

The impact of face familiarity on the speechreadability of faces is examined. First we measured the baseline speechreading performance of participants, from unfamiliar faces. Next, participants were familiarized with the face and voice of either the same or a different speaker, or were asked to take part in a word puzzle instead. Speechreading performance was measured again, before participants completed a further period of familiarization (or puzzle completion) and a final speechreading performance task. Results showed that speechreading performance increased overall with practice but that performance increased significantly more as participants became increasingly familiar with the same speaker. Our findings demonstrate the importance of talker-specific variations or other instance-based characteristics and suggest that these are a useful source of information for speechreading.

“Just another pretty face”: A multidimensional scaling approach to face attractiveness and variability

Findings on both attractiveness and memory for faces suggest that people should perceive more similarity among attractive than among unattractive faces. A multidimensional scaling approach was used to test this hypothesis in two studies. In Study 1, we derived a psychological face space from similarity ratings of attractive and unattractive Caucasian female faces. In Study 2, we derived a face space for attractive and unattractive male faces of Caucasians and non-Caucasians. Both studies confirm that attractive faces are indeed more tightly clustered than unattractive faces in people’s psychological face spaces. These studies provide direct and original support for theoretical assumptions previously made in the face space and face memory literatures.     

Do face masks undermine social connection?

Mask mandates were commonplace around the world during the COVID-19 pandemic and essential to slowing the spread of SARS-CoV-2. However, it is still unclear whether and how masks impact social bonding. Building on past research examining the effects of masking on emotion recognition and social perception, the current research examines the effect of masking on feelings of social connectedness. Three studies (total N = 177) using videotaped introductions of masked and unmasked peers and varied assessments of desire for social connectedness yielded no differences as a function of masking. Although participants reported more difficulty hearing masked (vs. unmasked) peers, masking did not significantly impact other facets of communication or perception related to social bonding. When participants filmed their own introductory videos (Study 3), results showed increased expressivity within the masked (vs. unmasked) conditions, perhaps as a compensatory measure to aid bonding. These findings speak to the resiliency of the human need to belong and belonging-maintenance processes.     

What's so special about the average face?

The past few years have seen a marked increase in our understanding of how faces are represented in the brain, with the discovery of new anatomical structures and new algorithms for representing faces. Still, the basic computational mechanism used by the primate visual system to identify faces remains a topic of intense debate. Are faces represented by matching to a set of stored exemplars, or by measuring the distance from a standard prototype along a set of different axes? A recent article by Rhodes and Jeffery provides compelling psychophysical evidence in favor of the latter 'axis' model.     

What can a moving face tell us?

This research assessed the impact of facial motion on perceptions of age-related person qualities. Ss judged the power of point-light displays of the faces of children, middle-aged adults, and elderly adults. Ratings were obtained of (a) dynamic displays filmed while the stimulus persons were reciting the alphabet, (b) dynamic displays filmed, while the stimulus persons engaged in an interaction, and (c) static versions of the displays. Facial age exerted no effect on the perceived power of nondynamic displays. However, moving displays of children's faces were judged to be less powerful than were those of adults. Differences in perceived age could not explain these effects. The implications of these data for the developing area of social event perception are discussed.     

Concerning Gibson's ‘on the face of it’: Immediate perception and single-glance face recognition

The paper notes (1) that “thinking Gibsonian” is to be torn between two loves: cognition and reality, (2) that just because of this the cognitive scientist may beneficiently and more thoroughly rediscover that they are only two faces of his one true love: Meaning. This issue is elaborated as “the problem of intentionality” and culminates in the conclusion that Gibson's direct ecological approach to visual perception is not a theory about the constitution of perceptual meaning, which is the domain of the indirect cognitive approach. Therefore the constant Gibsonian attacks on indirect theories might be both misled and misleading. The second half of the paper begins with noting that this may be due to a confounding of the “direct” level of explanation of the perceiver with the “indirect” levels of phenomenologist and visual scientist. Next the scientist's process notions of direct and indirect theories are discussed with respect to single-glance face recognition. Within this second half of the paper about 20 different meanings of “direct” or “immediate” are presented (printed in italics). Most of these are generally acceptable and should, thus, not be invoked in support of entirely different notions, which are very problematic because these seem to eliminate the concept of mind-as-cognitive-process.     

I’d know that face anywhere!

Mandler (1980) provided the classic “butcher on the bus” example illustrating the feeling of familiarity without recollection that may arise when an acquaintance is encountered in an unusual context. We studied this phenomenon by pairing photos of faces with photos of distinctive contexts at study and later testing recognition memory andremember/know judgments for faces presented with studied, switched, or new contexts. Estimates of recollection and familiarity, based on the assumption that these processes are independent, showed that switching contexts significantly lowered recollection while leaving familiarity intact, just as Mandler described. False alarm rates were higher with old contexts, suggesting that subjects tended to misattribute memories of contexts to memories of faces. These results provide the first evidence of context effects on the subjective experience of recognizing faces. One-dimensional signal-detection models fit the data, but such models do not explain the difference in remember responses between studied and switched items, whereas dual-process models (which also fit the data) do while also capturing the phenomenology of the butcher-on-the-bus experience in an intuitively appealing way.     

Does response interference contribute to face composite effects?

Holistic processing of faces can be measured as a failure of selective attention to one face-half under instructions to ignore the other face-half in a naming or same/different matching task. But is interference from the irrelevant half due to response interference rather than to holistic processing? Here, participants learned to name two faces “Fred” and two “Bob.” At test, composites were created from top and bottom halves of different learned faces or of a novel face, and composites were either aligned or misaligned. Naming was slower when the irrelevant half was from a different face as opposed to the same face, regardless of whether it was associated with the same name, a different name, or no name, suggesting holistic processing. Interference was eliminated when composite halves were misaligned. These results suggest that, unlike Stroop effects, composite effects are not due to response interference.     

Is computer simulation changing the face of experimentation?

Morrison points out many similarities between the roles of simulation models and other sorts of models in science. On the basis of these similarities she claims that running a simulation is epistemologically on a par with doing a traditional experiment and that the output of a simulation therefore counts as a measurement. I agree with her premises but reject the inference. The epistemological payoff of a traditional experiment is greater (or less) confidence in the fit between a model and a target system. The source of this payoff is the existence of a causal interaction with the target system. A computer experiment, which does not go beyond the simulation system itself, lacks any such interaction. So computer experiments cannot confer any additional confidence in the fit (or lack thereof) between the simulation model and the target system.     

The development of norm-based coding and race-specific face prototypes: An examination of 5- and 8-year-olds’ face space

The current research investigated the organization of children’s face space by examining whether 5- and 8-year-olds show race-contingent aftereffects. Participants read a storybook in which Caucasian and Chinese children’s faces were distorted in opposite directions. Before and after adaptation, participants judged the normality/attractiveness of expanded, compressed, and undistorted Caucasian and Chinese faces. The method was validated with adults and then refined to test 8- and 5-year-olds. The 5-year-olds were also tested in a simple aftereffects paradigm. The current research provides the first evidence for simple attractiveness aftereffects in 5-year-olds and for race-contingent aftereffects in both 5- and 8-year-olds. Evidence that adults and 5-year-olds may possess only a weak prototype for Chinese children’s faces suggests that Caucasian adults’ prototype for Chinese adult faces does not generalize to child faces and that children’s face space undergoes a period of increasing differentiation between 5 and 8 years of age.     

Extraversion predicts individual differences in women’s face preferences

Extraversion is positively associated with various indices of women’s mate quality (e.g., facial symmetry and attractiveness). Since such indices are thought to predict variation in women’s preferences for masculine men, we investigated the relationships between each of the ‘Big 5’ personality factors and women’s preferences for facial masculinity. Extraversion, but not the other four personality factors, was positively correlated with women’s preferences for masculinity in men’s, but not women’s, faces. Additionally, extraversion mediated the positive relationship between women’s self-rated attractiveness and their preferences for masculinity in men’s faces, suggesting that extraversion may play a role in condition-dependent mate preferences. Unexpectedly, openness to experience was associated with women’s preferences for femininity in faces of both sexes and this association was independent of that between extraversion and women’s preferences for masculine men. This is the first study that we know of to implicate personality traits in individual differences in women’s preferences for masculine men.     

Haven't we met somewhere before? The effects of a brief internet introduction on social anxiety in a subsequent face to face interaction

Social anxiety occurs in a range of social situations, the salience of which is influenced by prevailing modes of social contact. The emergence of computer mediated communication (CMC), buoyed by the recent explosion of social networks, has changed the way many people make and maintain social contacts. We randomly assigned 30 socially anxious and 30 low social anxiety participants to a brief internet chat introduction or a control internet surfing condition followed by a standardized face to face (FTF) interaction. We hypothesized that for socially anxious participants the chat introduction would reduce anxiety of and preference to avoid the subsequent FTF interaction. Results supported hypotheses for most indices. Findings suggest that, at least for the common situation in which internet chat precedes FTF interaction with the same person, such contact may reduce social anxiety. It is not known whether this decrease would generalize to FTF contact in other contexts. It is suggested that CMC might be construed as a particularly useful form of safety behavior that may help in the allocation of attentional resources to process new information relevant for disconfirmation of negative beliefs maintaining social anxiety. Potential clinical implications are discussed.     

Testing protects against proactive interference in face–name learning

Learning face–name pairings at a social function becomes increasingly more difficult the more individuals one meets. This phenomenon is attributable to proactive interference—the negative influence of prior learning on subsequent learning. Recent evidence suggests that taking a memory test can alleviate proactive interference in verbal list learning paradigms. We apply this technique to face–name pair learning. Participants studied four lists of 12 face–name pairings and either attempted to name the 12 faces just studied after every list or did not. Recall attempts after every list improved learning of the fourth list by over 100%. Moreover, no reduction in learning of face–name pairings occurred from list 1 to list 4 for participants who attempted to name studied faces between lists. These results suggest that testing oneself on the names of a group of new acquaintances before moving on to the next group is an effective mnemonic technique for social functions.     

The face typicality-recognizability relationship: Encoding or retrieval locus?

Using a crossover recognition memory testing paradigm, we tested whether the effects on face recognition of the memorability component of face typicality (Vokey & Read, 1992, 1995) are due primarily to the encoding process occurring during study or to the retrieval process occurring at test. At study, faces were either veridical in form or at moderate (Experiment 1) or extreme (Experiment 2) levels of caricature. The variable of degree of facial caricature at study was crossed with the degree of caricature at test. The primary contribution of increased memorability to increased hit rate was through increased distinctiveness at study. Increased distinctiveness at test contributed to substantial reductions in the false alarm rate, too. Signal detection analyses confirmed that the mirror effects obtained were primarily stimulus/memory-based, rather than decision-based. Contrary to the conclusion of Vokey and Read (1992), we found that increments in face memorability produced increments in face recognition that were due at least as much to enhanced encoding of studied faces as they were to increased rejection of distractor faces.
