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},

abstract = {Face recognition strategies do not generalize across individuals. Many studies have reported robust cultural differences between West Europeans/North Americans and East Asians in eye movement strategies during face recognition. The social orientation hypothesis posits that individualistic vs. collectivistic (IND/COL) value systems, respectively defining West European/North American and East Asian societies, would be at the root of many cultural differences in visual perception. Whether social orientation is also responsible for such cultural contrast in face recognition remains to be clarified. To this aim, we conducted two experiments with West European/North American and Chinese observers. In Experiment 1, we probed the existence of a link between IND/COL social values and eye movements during face recognition, by using an IND/COL priming paradigm. In Experiment 2, we dissected the latter relationship in greater depth, by using two IND/COL questionnaires, including subdimensions to those concepts. In both studies, cultural differences in fixation patterns were revealed between West European/North American and East Asian observers. Priming IND/ COL values did not modulate eye movement visual sampling strategies, and only specific subdimensions of the IND/COL questionnaires were associated with distinct eye-movement patterns. Altogether, we show that the typical contrast between IND/COL cannot fully account for cultural differences in eye movement strategies for face recognition.
