abstract = {Face detection feels effortless, yet it requires finely tuned computations to extract socially meaningful signals from the visual stream. Here, we used the Bubbles method to isolate the facial features and spatial frequency information that support face categorization. Across three experiments varying in task demands and visual context, the eye region consistently emerged as the most diagnostic source of information, particularly in high spatial frequencies. This finding held whether participants distinguished faces from noise, from non-face objects, or from real-world categories—suggesting that the eyes serve as an anchor point for categorization across contexts. Strikingly, this diagnostic profile mirrors that found in face identification tasks, implying that detection and recognition may rely on shared perceptual mechanisms rather than sequential, independent processes. This overlap sheds light on longstanding ambiguities in the prosopagnosia literature, indicating that detection impairments found in patients may stem from a broader failure to extract critical eye information. More broadly, our results invite a rethinking of the early stages of face processing, suggesting that detection already involves selective use of diagnostic facial features that supports recognition, emotional decoding, and social perception. © 2026 The Author(s).},

abstract = {Previous research has identified cultural differences in visual perception, where East Asians focus more on global object structure and display a larger breadth of attention compared with Westerners. East Asians rely on lower spatial frequencies (SFs) compared to Westerners for face recognition, which may be linked to this. Investigating whether such differences extend to other high-level stimulus categories would clarify if SF tuning differences reflect more general or face specific cognitive processes. The present study compared the SF tunings of Canadians and Chinese during object (Exp. 1; N = 50) and scene (Exp. 3; N = 47) categorization. In both experiments, results did not indicate a significant difference between groups. In Experiment 3 (N = 128), we conducted an online replication of Experiment 1 while measuring the SF tunings of the same participants during face perception. Again, no significant difference between the groups was found during object categorization, but the finding that East Asians rely on lower SF than Westerners was replicated. Together, these results suggest that unique mechanisms may underlie the cultural differences in face processing, though alternative explanations, such as the feature consistency of faces, could also account for these findings. © The Psychonomic Society, Inc. 2025.},

abstract = {Faces are rapidly and automatically assessed on multiple social dimensions, including trustworthiness. The high inter-rater agreement on this social judgment suggests a systematic association between facial appearance and perceived trustworthiness. The facial information used by observers during explicit trustworthiness judgments has been studied before. However, it remains unknown whether the same perceptual strategies are used during decisions that involve trusting another individual, without necessitating an explicit trustworthiness judgment. To explore this, 53 participants completed the Trust Game, an economic decision task, while facial information was randomly sampled using the Bubbles method. Our results show that economic decisions based on facial cues rely on similar visual information as that used during explicit trustworthiness judgments. We then manipulated facial features identified as diagnostic for trust to test their influence on perceived trustworthiness (Experiment 2) and on trust-related behaviors (Experiment 3). Across all experiments, subtle, targeted changes to facial features systematically shifted both impressions and monetary trust decisions. These findings demonstrate that the same perceptual strategies underlie explicit judgments and trust behaviors, highlighting the applied relevance of even minimal alterations in facial appearance. These findings should be replicated with real faces from diverse demographic backgrounds to confirm their generalizability. © The Author(s) 2025.

abstract = {While line vertices, terminations, and midsegments are critical for Roman letter identification, the diagnostic features of Chinese character strokes remain unclear. This study examines how local stroke-level features and global line-relation mechanisms contribute to Chinese character recognition. In Experiment 1, we applied the Bubbles classification image technique to native Chinese readers to identify diagnostic stroke features. Results revealed four key features: horizontal hooks, dots, vertical turnings, and raises. These features, while analogous to terminations in alphabetic systems, reflect unique dynamics of Chinese stroke production, marking stroke origins and terminations. Experiment 2 employed a delayed-segment paradigm to assess functional significance of these features. Greater degradation of vertices and midsegments significantly prolonged reaction times, and removal of stroke-based terminations (e.g., hooks) impaired recognition accuracy. Together, these findings support a two-tiered hierarchy in Chinese character recognition: stroke-specific terminals enable fine-grained feature discrimination, while line-relation features support global structural integration. The results affirm script-general principles (midsegments and vertices as perceptual anchors) and highlight language-specific adaptations, where stroke terminations function as dynamic positional cues. © Experimental Psychology Society 2025},

abstract = {Facial expressions are crucial in human communication. Recent decades have seen growing interest in understanding the role of spatial frequencies (SFs) in emotion perception in others. While some studies have suggested a preferential treatment of low versus high SFs, the optimal SFs for recognizing basic facial expressions remain elusive. This study, conducted on Western participants, addresses this gap using two complementary methods: a data-driven method (Exp. 1) without arbitrary SF cut-offs, and a more naturalistic method (Exp. 2) simulating variations in viewing distance. Results generally showed a preponderant role of low over high SFs, but particularly stress that facial expression categorization mostly relies on mid-range SF content (i.e. ∼6–13 cycles per face), often overlooked in previous studies. Optimal performance was observed at short to medium viewing distances (1.2–2.4 m), declining sharply with increased distance, precisely when mid-range SFs were no longer available. Additionally, our data suggest variations in SF tuning profiles across basic facial expressions and nuanced contributions from low and mid SFs in facial expression processing. Most importantly, it suggests that any method that removes mid-SF content has the downfall of offering an incomplete account of SFs diagnosticity for facial expression recognition. © 2025 The Authors},

abstract = {Background: Childhood maltreatment can disrupt socio-emotional functioning, potentially influencing how parents respond to children's emotional facial expressions. Mimicry, an automatic reaction to others' facial expressions, is a critical mechanism for social bonding and affiliation in parent-child relationships. However, the effects of childhood maltreatment on parental mimicry remain underexplored. Objective: This study examined the relationship between different forms of childhood maltreatment and parents' mimicry of children's emotional facial expressions. Participants and setting: Fifty-seven parents participated in an emotion recognition task conducted either at a local community organization or at the university laboratory. Methods: Parents' facial reactions were recorded and analyzed using FaceReader software to detect mimicry. The Childhood Trauma Questionnaire (CTQ) assessed parental history of maltreatment. A path analysis model was conducted to evaluate the associations between forms of childhood maltreatment and parental mimicry. Results: A history of physical abuse predicted increased expressions of anger, while physical neglect was linked to reduced anger but heightened disgust. Emotional and sexual abuse were associated with diminished mimicry of sadness, whereas emotional neglect predicted enhanced sadness mimicry. Conclusions: Findings suggest that childhood maltreatment alters parents' facial reactions to children's emotional facial expressions, potentially impacting parental sensitivity. © 2025},

A sample of 58 mothers and their children aged between 2 and 5 years old were recruited. Parents' history of maltreatment was measured using the Child Trauma Questionnaire. An emotion recognition task was performed. Mothers identified the dominant emotion in morphed facial emotion expressions in children. Mothers and children interacted for 15 minutes. Salivary cortisol levels of mothers were collected before and after the interaction. Maternal sensitive behaviors were coded during the interaction using the Coding Interactive Behavior scheme. Results indicate that the severity of childhood maltreatment is related to less sensitive behaviors for mothers with average to good abilities in emotion recognition and lower to average increases in cortisol levels following an interaction with their children. For mothers with higher cortisol levels, there is no association between a history of maltreatment and sensitive behaviors, indicating that higher stress reactivity could act as a protective factor. Our study highlights the complex interaction between individual characteristics and environmental factors when it comes to parenting.

Two face recognition experiments based on a data-driven psychophysical method involving real-time stimulus manipulation and relying on functions from the Psychtoolbox were tested. In Experiment 1, the visual information used for face recognition was compared across four conditions that gradually reduced experimental control over the testing environment and stimulus properties. In Experiment 2, the association between face recognition abilities and information utilization was measured online and compared to lab-based results. In both experiments, results obtained in the lab and online were highly similar, demonstrating the potential of online research for vision science. © 2025 The Author(s)},

A multiple linear regression including three predictors, namely perceptual integration, part-based efficiency, and object processing, explained 40 % of the variance in FPA. Most importantly, our results reveal a strong predictive relationship between part-based efficiency and FPA, a small predictive relationship between object processing ability and FPA, and no predictive relationship between perceptual integration and FPA. This result was obtained despite considerable variance in perceptual integration skills–with some participants exhibiting a highly efficient integration.
