In this study both the matching and developmental trajectories approaches were used to clarify the development of facial expression recognition in Williams syndrome (WS) and Down syndrome (DS). The matching approach showed that neither individuals with WS nor DS exhibit a specific proficiency for the expression of happiness or a specific impairments for negative emotions but presented the same pattern of emotion recognition as typically developing (TD) individuals. Thus, the better performance on the recognition of positive compared to negative emotions often reported in WS and DS is not specific to these populations but represents a typical pattern. Prior studies based on the matching approach suggested that the development of facial expression recognition is delayed in WS and atypical in DS. Nevertheless, and even though performance levels were lower in DS than in WS, the developmental trajectories approach used in this study found that not only individuals with DS but also those with WS present atypical developmental trajectories. Unlike in the TD participants where developmental changes were observed along with age, in the WS and DS development was static. Thus, both individuals with WS and those with DS reach early maximum levels of facial expression recognition due to cognitive constraints.
