The capacity to discriminate between different facial expressions of emotion (FEE) has been reported from birth, and the literature throughout infancy has shown unique attentional responses to facial expressions of specific emotional categories, such as happiness and fear. However, the role of affective properties, such as valence and arousal, is still understudied in infant FEE processing and emotional understanding. Using a habituation/novelty preference task, the current study aimed to understand the development of facial valence and arousal discrimination across the first two years of life. The task included an initial habituation period to induce a prediction of a facial display, an expression of happiness with low arousal, followed by a novelty preference task pairing the expected expression with a novel FEE on the same screen. The novel FEE could differ from the expected FEE in valence (valence-mismatch screens) or arousal (arousal-mismatch screens). The study included 100 infants aged between 2 and 25 months, and visual preference for the novel expressions, as well as positive and negative reactions, were measured to assess novelty detection and affective understanding. Results suggested different trajectories for valence-mismatch and arousal-mismatch, as well as some unique effects per emotional category. The potential of a hybrid model to explain FEE processing in infancy and the relevance of predictive processing models to understand emotional development are discussed.
