Older adults' configural processing of faces: role of second-order information

Problems with face recognition are frequent in older adults. However, the mechanisms involved have only been partially discovered. In particular, it is unknown to what extent these problems may be related to changes in configural face processing. Here, we investigated the face inversion effect (FIE) together with the ability to detect modifications in the vertical or horizontal second-order relations between facial features. We used a same/different unfamiliar face discrimination task with 33 young and 33 older adults. The results showed dissociations in the performances of older versus younger adults. There was a lack of inversion effect during the recognition of original faces by older adults. However, for modified faces, older adults showed a pattern of performance similar to that of young participants, with preserved FIE for vertically modified faces and no detectable FIE for horizontally modified faces. Most importantly, the detection of vertical modifications was preserved in older relative to young adults whereas the detection of horizontal modifications was markedly diminished. We conclude that age has dissociable effects on configural face-encoding processes, with a relative preservation of vertical compared to horizontal second-order relations processing. These results help to understand some divergent results in the literature and may explain the spared familiar face identification abilities in the daily lives of older adults.     

Memory conjunction errors for realistic faces are consistent with configural processing

Conjunction faces are formed from feature sets learned across different faces. In previous studies, false alarms (“old” responses) to conjunctions have been very high, approaching hits to old faces; this is surprising, because, perceptually, upright faces are processed configurally, with strong integration of parts into the whole. We test the idea that the atypical reliance on unrelated parts could be due to using unnatural line drawings as stimuli, and to forming conjunctions across external features (e.g., hair) and internal features (e.g., eyes, mouth). We used realistic face stimuli and conjunctions made entirely from internal features. Results were, as expected, consistent with configural processing for upright faces (hits to old faces much greater than FA to conjunctions) and not for inverted faces (hits to old = FA to conjunctions).     

The many faces of self-harm

This paper explores why open dialogue on the subject of erotic transference and countertransference is so difficult and attempts to offer an understanding of these phenomena which might enable counsellors to work more confidently with it. It also briefly examines the author's own research on therapists' thoughts and experiences of erotic transference, seeking to differentiate between inappropriate sexual contact between clients and therapists and the experience of erotic transference in the context of therapy as a reworking of the Oedipal relationship. Case examples illustrating the experience of countertransference within the therapeutic situation and how its presence can act as a help or a hindrance are offered. The paper concludes by examining the need to reflect on the erotic transference in therapeutic work and proposes its usefulness as a therapeutic tool. Suggestions about how the erotic transference can be managed to therapeutic effect are also explored.     

The many faces of amnesia

Results from studies of retrograde amnesia provide much of the evidence for theories of memory consolidation. Retrograde amnesia gradients are often interpreted as revealing the time needed for the formation of long-term memories. The rapid forgetting observed after many amnestic treatments, including protein synthesis inhibitors, and the parallel decay seen in long-term potentiation experiments are presumed to reveal the duration of short-term memory processing. However, there is clear and consistent evidence that the time courses obtained in these amnesia experiments are highly variable within and across experiments and treatments. The evidence is inconsistent with identification of basic temporal properties of memory consolidation. Alternative views include modulation of memory and emphasize the roles that hormones and neurotransmitters have in regulating memory formation. Of related interest, converging lines of evidence suggest that inhibitors of protein synthesis and of other biochemical processes act on modulators of memory formation rather than on mechanisms of memory formation. Based on these findings, memory consolidation and reconsolidation studies might better be identified as memory modulation and "remodulation" studies. Beyond a missing and perhaps unattainable time constant of memory consolidation, some current views of memory consolidation assume that memories, once formed, are generally unmodifiable. It is this perspective that appears to have led to the recent interest in memory reconsolidation. But the view adopted here is that memories are continually malleable, being updated by new experiences and, at the same time, altering the memories of later experiences. Studies of memory remodulation offer promise of understanding the neurobiological bases by which new memories are altered by prior experiences and by which old memories are altered by new experiences.     

The many faces of interpolation

We present a number of, somewhat unusual, ways of describing what Craig’s interpolation theorem achieves, and use them to identify some open problems and further directions.     

The many faces of autonomy

What does autonomy mean from a moral point of view? Throughout Western history, autonomy has had no less than four different meanings. The first is political: the capacity of old cities and modern states to give themselves their own laws. The second is metaphysical, and was introduced by Kant in the second half of the 18th century. In this meaning, autonomy is understood as an intrinsic characteristic of all rational beings. Opposed to this is the legal meaning, in which actions are called autonomous when performed with due information and competency and without coercion. This last meaning, the most frequently used in bioethics, is primarily legal instead of moral. Is there a proper moral meaning of the word autonomy? If so, this would be a fourth meaning. Acts can only be called moral when they are postconventional (using the terminology coined by Lawrence Kohlberg), inner-directed (as expressed by David Riesman), and responsible (according to Hannah Arendt). Such acts are autonomous in this new, fourth, and to my mind, the only one proper, moral meaning. The goal of ethics cannot be other than forming human beings capable of making autonomous and responsible decisions, and doing so because they think this is their duty and not because of any other nonmoral motivation, like comfort, convenience, or satisfaction. The goal of ethics is to promote postconventional and mature human beings. This was what Socrates tried to do with the young people of Athens. And it is also the objective of every course of ethics and of any process of training.     

The many faces of lying

In this paper the author explores the psychic functions of lying and draws on Glasser's (1979) notions of self-preservative and sadistic violence to identify three selfobject configurations. Each of these is associated with specific anxieties to which the lie offers an apparent solution. The first configuration is sadistic lying. Here the intent is to attack and triumph over the duped other. The lie allows the object to be controlled and humiliated. This gratifies the self by reversing an earlier humiliation. The second and third configurations are both forms of self-preservative lying, where the lie may be best conceived as a symptom of hope (Winnicott, 1985). In the second configuration, the object is felt to be unavailable or inscrutable. The lie may be used to create an attractive self that will elicit the object's love, admiration and concern. In this way, the lie serves to eliminate doubt about the object's intentions towards the self. In the third configuration, the object is felt to be intrusive, and the dyadic relationship is overpowering. Here the lie can represent an attempt to insert a third into the relationship.     

Converging evidence of configural processing of faces in high-functioning adults with autism spectrum disorders

There is conflicting evidence about whether individuals with autism spectrum disorder (ASD) demonstrate configural processing of faces. We examined two types of configural processing of unfamiliar faces in high-functioning adults with ASD: Holistic processing (processing a face as a gestalt percept) and processing of second-order relations (the spatial relations among facial features, e.g., distance between two eyes). Compared to age- and IQ-matched typical adults, 17 adults with ASD demonstrated normal holistic processing (as demonstrated by the composite face effect), normal sensitivity to second-order relations in upright faces, and the expected disruption of sensitivity to second-order relations in inverted faces. They were also normal in using the internal features and shape of the external contour to make same/different judgements about facial identity. The results provide converging evidence of configural processing of unfamiliar faces in high-functioning adults with ASD, and bring into question the generalizability of previous reports of abnormal face processing in individuals with ASD.     

The respective role of low and high spatial frequencies in supporting configural and featural processing of faces

One distinctive feature of processing faces, as compared to other categories, is thought to be the large dependence on configural cues such as the metric relations among features. To test the role of low spatial frequencies (LSFs) and high spatial frequencies (HSFs) in configural and featural processing, subjects were presented with triplets of faces that were filtered to preserve either LSFs (below 8 cycles per face width), HSFs (above 32 cycles per face width), or the full frequency spectrum. They were asked to match one of two probe faces to a target face. The distractor probe face differed from the target either configurally, featurally, or both featurally and configurally. When the difference was at the configural level, performance was better with LSF faces than with HSF faces. In contrast, with a featural difference, a strong performance advantage was found for HSF faces as compared to LSF faces. These results support the dominant role that LSFs play in the configural processing of faces, whereas featural processing is largely dependent on HSFs.     

Contact and other‐race effects in configural and component processing of faces

Other‐race faces are generally recognized more poorly than own‐race faces. There has been a long‐standing interest in the extent to which differences in contact contribute to this other‐race effect (ORE). Here, we examined the effect of contact on two distinct aspects of face memory, memory for configuration and for components, both of which are better for own‐race than other‐race faces. Configural and component memory were measured using recognition memory tests with intact study faces and blurred (isolates memory for configuration) and scrambled (isolates memory for components) test faces, respectively. Our participants were a large group of ethnically Chinese individuals who had resided in Australia for varying lengths of time, from a few weeks to 26 years. We found that time in a Western country significantly (negatively) predicted the size of the ORE for configural, but not component, memory. There was also a trend for earlier age of arrival to predict smaller OREs in configural, but not component, memory. These results suggest that memory for configural information in other‐race faces improves with experience with such faces. However, as found for recognition memory generally, the contact effects were small, indicating that other factors must play a substantial role in cross‐race differences in face memory.     

Tolerance for distorted faces: Challenges to a configural processing account of familiar face recognition

Face recognition is widely held to rely on ‘configural processing’, an analysis of spatial relations between facial features. We present three experiments in which viewers were shown distorted faces, and asked to resize these to their correct shape. Based on configural theories appealing to metric distances between features, we reason that this should be an easier task for familiar than unfamiliar faces (whose subtle arrangements of features are unknown). In fact, participants were inaccurate at this task, making between 8% and 13% errors across experiments. Importantly, we observed no advantage for familiar faces: in one experiment participants were more accurate with unfamiliars, and in two experiments there was no difference. These findings were not due to general task difficulty – participants were able to resize blocks of colour to target shapes (squares) more accurately. We also found an advantage of familiarity for resizing other stimuli (brand logos). If configural processing does underlie face recognition, these results place constraints on the definition of ‘configural’. Alternatively, familiar face recognition might rely on more complex criteria – based on tolerance to within-person variation rather than highly specific measurement.     

Introduction: The many faces of context

This paper introduces a special issue of the journal Personal Relationships dealing with context and relationships. It reflects on the state of the literature and discusses five approaches to the interplay of context and relationships.     

Perceptual integrality of componential and configural information in faces

The relative contribution of componential and configural information to face perception is controversial. We addressed this issue in the present study by examining how componential information and configural information interact during face processing, using Garner’s (1974) speeded classification paradigm. When classifying upright faces varying in components (eyes, nose, and mouth) and configural information (intereyes and nose-mouth spacing), observers could not selectively attend to components without being influenced by irrelevant variation in configural information, and vice versa, indicating that componential information and configural information are integral in upright face processing. Performance with inverted faces showed selective attention to components but not to configural information, implying dominance of componential information in processing inverted faces. When faces varied only in components, selective attention to different components was observed in upright and inverted faces, indicating that facial components are perceptually separable. These results provide strong evidence that integrality of componential and configural information, rather than the relative dominance of either, is the hallmark of upright face perception.     

Attention to configural information in change detection for faces

In recent research the change-detection paradigm has been used along with cueing manipulations to show that more attention is allocated to the upper than lower facial region, and that this attentional allocation is disrupted by inversion. We report two experiments the object of which was to investigate how the type of information changed might be a factor in these findings by explicitly comparing the role of attention in detecting change to information thought to be 'special' to faces (second-order relations) with information that is more useful for basic-level object discrimination (first-order relations). Results suggest that attention is automatically directed to second-order relations in upright faces, but not first-order relations, and that this pattern of attentional allocation is similar across features.     

The many faces of working memory and short-term storage

The topic of working memory (WM) is ubiquitous in research on cognitive psychology and on individual differences. According to one definition, it is a small amount of information kept in a temporary state of heightened accessibility; it is used in most types of communication and problem solving. Short-term storage has been defined as the passive (i.e., non-attention-based, nonstrategic) component of WM or, alternatively, as a passive store separate from an attention-based WM. Here I note that much confusion has been created by the use by various investigators of many, subtly different definitions of WM and short-term storage. The definitions are sometimes made explicit and sometimes implied. As I explain, the different definitions may have stemmed from the use of a wide variety of techniques to explore WM, along with differences in theoretical orientation. By delineating nine previously used definitions of WM and explaining how additional ones may emerge from combinations of these nine, I hope to improve scientific discourse on WM. The potential advantages of clarity about definitions of WM and short-term storage are illustrated with respect to several ongoing research controversies.     

When inverted faces are recognized: The role of configural information in face recognition

The identification of upright faces seems to involve a special sensitivity to "configural" information, the processing of which is less effective when the face is inverted. However the precise meaning of "configural" remains unclear. Five experiments are presented, which showed that the disruption of the processing of relational, rather than holistic, information largely determines the occurrence as well as the size of the face-inversion effect. In Experiment 1, faces could be identified either by unique combinations of local information (e.g. a specific eye colour plus hair colour) or by unique relational information (e.g. nose-mouth distance). The former showed no inversion effect, whereas the latter did. A combination of local and relational information (Experiment 2) again produced an inversion effect, although this effect was smaller than that found when only relational information was used. The results were replicated in Experiment 3 when differences in the brightness of local features were used instead of specific colour combinations. Experiment 4 used different retrieval conditions to distinguish relational from holistic processing, and demonstrated again that spatial relations between single features appeared to provide crucial information for face recognition. In Experiment 5, the importance of relational information was confirmed using faces that also varied in the shapes of local features.     

The many faces of assumed similarity in perceptions of personality

We propose that most coefficients of assumed similarity in acquaintance ratings are based on actual similarity between observer and target rather than any bias to project self onto other. We assessed assumed similarity, actual similarity, and rater accuracy in 62 university roommate dyads who rated each other on 74 personality-related variables. Our findings indicate that our roommates (a) were actually alike on many variables, (b) knew this, rather than assumed it, and (c) applied this knowledge to enhance the accuracy of their ratings. We outline a model of judgment that urges three distinct concepts: true assumed similarity, known similarity, and spurious similarity. We conclude that personality ratings among acquaintances reflecting true assumed similarity are probably rare.     

The many faces of self: ego and ethnic identities

This study addressed how adolescents come to develop a sense of ethnic identity. The author examined ethnic identity development as a process that occurs simultaneously with the development of ego identity and attitudes toward groups other than one's own. A multiethnic sample of 297 adolescents and young adults (aged 13 to 26 years) completed the Extended Objective Measure of Ego Identity Scale Revision 2 (EOMEIS2; L. Bennion & G. Adams, 1986), the Multigroup Ethnic Identity Measure (MEIM; J. Phinney, 1992), and the Other Group Orientation Scale (J. Phinney, 1992). An Age x Ethnic Group x Gender experimental design was used to determine whether these factors contributed differently to ethnic identity and ego identity. Analyses showed significant differences in the level of ethnic identity development among the ethnic groups. More pronounced age differences were found at the lower levels of ego identity development than at the more advanced levels.     

The many faces of stereotype threat: Group- and self-threat

Contending with negative intellectual stereotypes has been shown to depress the academic performance of targets of the stereotypes [Steele, C. M. (1997). A threat in the air: How stereotypes shape intellectual identity and performance. American Psychologist, 52, 613-629]. The present paper examines whether women’s mathematics performance is differentially affected by the concern of confirming that a negative stereotype is true of the self (self-threat), than by the concern of confirming that the stereotype is true of their gender (group-threat). In two studies we independently manipulated these different threats for women taking a mathematics test. Gender identification moderated the effect of group-threats on test performance; only women highly identified with their gender underperformed. The performance of less gender-identified women was unaffected by group-threats. In contrast, gender identification did not moderate the effect of self-threats—both high- and low-identified women underperformed. The results of these studies suggest that women’s math performance is differentially affected by the source of the threat.
