“…Here, the earliest ERP attractiveness effect was observed in the test phase P2, with more positive amplitudes for unattractive faces. P2 has been shown to be more positive for veridical relative to spatially caricatured (Schulz, Kaufmann, Walther, et al, 2012), as well as for typical relative to naturally distinct faces (Schulz, Kaufmann, Kurt, et al, 2012). As the stimuli in the present study were matched for distinctiveness, attractiveness appears to affect P2 amplitude in addition to the distinctiveness effect described in these previous studies.…”

“…The LPC has been observed to be larger for affective than neutral pictures (Schupp et al, 2007), for emotional than neutral facial expressions (Schacht et al, 2008;Schupp et al, 2004), and for distinctive than typical faces (Schulz, Kaufmann, Kurt, et al, 2012;Schulz, Kaufmann, Walther, et al, 2012). The LPC has been interpreted as reflecting an engagement towards motivationally significant stimuli (Cuthbert, Schupp, Bradley, Birbaumer, & Lang, 2000), and has also been shown to be larger for attractive relative to unattractive faces (Schacht et al, 2008;Werheid et al, 2007).…”

“…This P2 has been interpreted to reflect the processing of metric distances between facial features (e.g., Latinus & Taylor, 2006) or the perceived typicality of a face (e.g., Wiese, Kaufmann, & Schweinberger, in press), and is modulated by an observer's expertise with a specific facial category (Stahl, Wiese, & Schweinberger, 2008). Interestingly, a number of recent studies found smaller P2 components for naturally distinctive relative to more typical faces (Schulz, Kaufmann, Kurt, & Schweinberger, 2012), as well as for spatial caricatures relative to veridical faces Schulz, Kaufmann, Walther, & Schweinberger, 2012). To the best of our knowledge, no previous study examined attractiveness effects on P2 using natural faces (though Halit et al, 2000, experiment 1, report a smaller P2 for unattractive faces with artificially increased distances between features).…”

AbstractThe present study examined effects of attractiveness on behavioral and event-related potential (ERP) correlates of face memory. Extending previous reports, we controlled for potential moderating effects of distinctiveness, a variable known to affect memory. Attractive and unattractive faces were selected on the basis of a rating study, and were matched for distinctiveness. In a subsequent recognition memory experiment, we found more accurate memory for unattractive relative to attractive faces. Additionally, an attractiveness effect in the Early Posterior Negativity (EPN) during learning, with larger amplitudes for attractive than unattractive faces, correlated significantly with the magnitude of the memory advantage for unattractive faces at test. These findings establish a contribution of attractiveness to face memory over and above the well-known effect of distinctiveness. Additionally, as the EPN is typically enhanced for affective stimuli, our ERP results imply that the processing of emotionally relevant attractive faces during learning may hamper their encoding into memory.

“…Processes associated with this stage include detection and categorization of a face or facelike pattern. Occipito-temporal P2, a positive peak at approximately 200 ms following stimulus onset, has been suggested to relate to perceived typicality of a face (Schulz et al, 2012;Stahl et al, 2008). Finally, N250 and N250r ("r" for repetition) peak negatively over occipito-temporal sites between 230 and 330 ms, and have been linked to individual recognition of faces (Eimer et al, 2012;Schweinberger et al, 2004;Tanaka et al, 2006).…”

AbstractParticipants are more accurate at remembering faces from their own relative to a different age group (own-age bias, OAB). A recent socio-cognitive account suggests that differential allocation of attention to old versus young faces underlies this phenomenon. Critically, empirical evidence for a direct relationship between attention to own-versus other-age faces and the OAB in memory is lacking. To fill this gap, we tested the role of attention in three different experimental paradigms, and additionally analyzed event-related brain potentials (ERPs). Experiment 1 compared learning of old and young faces during focused versus divided attention, but revealed an equivalent OAB in subsequent memory for both attention conditions. Similarly, attention manipulation during learning did not differentially affect ERPs elicited by young versus old faces. Experiment 2 examined repetition effects from task-irrelevant old and young faces presented under varying attentional load on the N250r ERP component as an index of face recognition. Independent of load, N250r effects were comparable for both age categories. Finally, in Experiment 3 we measured N2pc as an index of attentional selection of old versus young target faces in a visual search task. N2pc was not significantly different for young versus old target search conditions, suggesting equivalent orientation of attention to either face age group. Overall, we propose that the OAB in memory is largely unrelated to early attentional processes. Our findings therefore contrast predictions from socio-cognitive accounts on own-group biases in recognition memory, and are more easily reconciled with expertise-based models.

Identification of faces from photographs is a common security measure, but matching unfamiliar faces produces high rates of error. Caricatures of familiar people are highly identifiable because they exaggerate distinctive features. We investigated whether exaggerating unfamiliar faces through caricaturing could also improve face-matching accuracy. In Experiment 1, facematching arrays were caricatured relative to an average by 30%, 50% and 70%. Correct rejection of the target-absent arrays was improved at all levels. Accurate matches increased at 30%, but at 70%, the transformation was too extreme, and all of the arrays were more likely to be rejected. In Experiment 2, photographic identification (ID) images were caricatured by 30% and 50% and matched to life-size photographs. Rejection of foils improved, but the ID of matching images was impaired. Modest levels of caricature may improve discrimination in unfamiliar face matching, but at stronger levels, a conservative response bias may inhibit accurate ID.
