AbstractFacial expressions are one way in which infants and adults communicate emotion. Infants scan expressions similarly to adults, yet it remains unclear whether they are receptive to the affective information they convey. The current study investigates 6‐, 9‐ and 12‐month infants' (N = 146) pupillary responses to the six "basic" emotional expressions (happy, sad, surprise, fear, anger, and disgust). To do this we use dynamic stimuli and gaze‐contingent eye‐tracking to simulate brief interactive exchanges, alongside a static control condition. Infants' arousal responses were stronger for dynamic compared to static stimuli. And for dynamic stimuli we found that, compared to neutral, infants showed dilatory responses for happy and angry expressions only. Although previous work has shown infants can discriminate perceptually between facial expressions, our data suggest that sensitivity to the affective content of all six basic emotional expressions may not fully emerge until later in ontogeny.

Purpose: To evaluate the effectiveness of an e-learning training module for improving children's social workers' knowledge of, and attitudes toward, LGBTQ+ young people. Methods: A pragmatic randomized, CONSORT-compliant controlled trial to compare an intervention group ( N = 304) with a business-as-usual comparison group ( N = 310). After attrition, the analysis included 188 (intervention) and 278 (comparison) participants. The main outcome measures were the Heteronormative Attitudes and Beliefs Scale and a perceived LGBTQ+ knowledge measure, controlling for several covariates. Results: A significant effect of intervention on both outcome measures, using several rigorous analysis approaches and missing data imputation methods. Participants who undertook the training decreased their heteronormative attitudes and beliefs and increased their perceived LGBTQ+ knowledge compared to business as usual. Conclusion: This study demonstrates the effectiveness of an e-learning training intervention in improving knowledge of, and attitudes toward, LGBTQ+ young people. Implications for research, practice, and policy are outlined.
