“…If our results generalise to these more naturalistic task demands, we might expect flexibility in the facial features sampled by an individual viewer to facilitate their discovery of diagnostic features as faces become familiar. Overall, it is possible that different task conditions might contribute additional variance in the features that are used in face identity processing (Leong et al, 2023; see also Smith & Merlusca, 2014). Future work should test flexibility in feature use across more diverse and naturalistic task demands.…”

People prioritise diagnostic features in classification tasks. However, it is not clear whether this priority is fixed or is flexibly applied depending on the specific classification decision, or how feature use behaviour contributes to individual differences in performance. Here we examined whether flexibility in features used in a face identification task supports face recognition ability. In Experiment 1, we show that the facial features most useful for identification vary – to a surprising degree – depending on the specific face identity comparison at hand. While the ears and eyes were most diagnostic for face identification in general, they were the most diagnostic feature for just 22% and 14% of identity decisions, respectively. In 3 subsequent experiments, we find that flexibility in feature use contributes to an individual’s face identity matching ability. Higher face identification accuracy was associated with being aware of (Experiments 2 & 4) and attending to (Experiments 3 & 4) the most diagnostic features for a specific facial comparison. This conferred an enhanced benefit relative to focusing on features that were diagnostic of face identity decisions in general (Experiment 4). We conclude that adaptability in information sampling supports face recognition ability and discuss theoretical and applied implications.

“…The final 10 models (6 Caucasian and 4 Eastern/Southeastern Asian) were average on all ratings 1 . We combined Eastern/Southeastern Asian faces into a broad ‘Asian’ category, as previous face recognition research has treated them as a single category [ 62 , 63 ], as do some face databases (e.g., Chicago Face Database) [ 64 ].…”

Background Remote research methods and interventions for mental health disorders have become increasingly important, particularly for conditions like eating disorders (EDs). Embodiment illusions, which induce feelings of ownership over another person?s body or body parts, offer valuable insights into the mechanisms underlying self-perception issues in EDs and potential interventions. However, existing research using these illusions has been limited to face-to-face settings. We illustrate a novel online protocol to induce the enfacement illusion (embodiment illusion principles applied to one’s face) in an ED-based sample. Methods Participants complete a 2-hr virtual session with a researcher. First, baseline trait/state ED psychopathology measures and a self-face recognition task occur. Second, participants experience two testing blocks of the enfacement illusion involving synchronously and asynchronously mimicking a pre-recorded actor’s facial expressions. After each block, subjective and objective enfacement illusion measures occur alongside state ED psychopathology reassessment. Discussion Successfully inducing enfacement illusions online could provide an affordable, accessible virtual approach to further elucidate the mechanistic role of self-perception disturbances across psychopathologies such as EDs. Moreover, this protocol may represent an innovative, remotely-delivered intervention strategy, as ‘enfacement’ over another face could update negative self-representations in a cost-effective, scalable manner.

Objective The present study aimed to examine facial emotion recognition in a sample from the general population with elevated schizotypal traits, as defined by the four-factor model of schizotypy, and the association of facial emotion recognition and the schizotypal dimensions with psychological well-being. Method Two hundred and thirty-eight participants were allocated into four schizotypal groups and one control group. Following a cross-sectional study design, facial emotion recognition was assessed with a computerized task that included images from the Radboud Faces Database, schizotypal traits were measured with the Schizotypal Personality Questionnaire, and psychological well-being was evaluated with the Flourishing scale. Results The results revealed distinct patterns of performance across the schizotypal groups and the application of a dimensional approach that included all participants as one group indicated specific associations between the four schizotypal dimensions and psychological well-being. Specifically, (a) negative schizotypes showed poor identification of sadness and fear potentially due to the activation of coping mechanisms, (b) disorganized schizotypes inaccurately recognized surprise, possibly reflecting the effects of disorganized thought on distinguishing this ambiguous emotion, and (c) psychological well-being was predicted by high cognitive-perceptual along with low negative and disorganized schizotypy as well as the accurate recognition of specific emotional states that are common in daily social interactions. Conclusions In conclusion, the study findings further advance the identification of emotion-processing difficulties in schizophrenia-vulnerable individuals and further highlight the need for highly personalized early intervention strategies.
