“…Laboratory investigations are most useful when their findings can be generalized to real social interactions, and this is most likely to be possible when the stimuli most closely reflect the social demands and real-world experiences. Using autism as an example, the unimodal emotion perception literature indicates mixed results when examining deficits in emotion processing; some studies indicate that individuals with ASD have difficulty identifying facial expressions (e.g., Adolphs, Sears, & Piven, 2001; Celani, Battacchi, & Arcidiacono, 1999; Hobson, Ouston, & Lee, 1988; Yirmiya, Sigman, Kasari, & Mundy, 1992), and emotional prosody (Boucher, Lewis, & Collis, 2000; Fujiki, Spackman, Brinton, & Illig, 2008; Peppe, McCann, Gibbon, O’Hare, & Rutherford, 2007), compared to typically developing children, whereas others find no significant differences between individuals with ASD and controls (Gepner et al, 2001; Ozonoff, Pennington, & Rogers, 1990). However, there have been very few studies examining the integration of audiovisual emotion cues in autism (e.g., Haviland, Walker-Andrews, Huffman, Toci, & Alton, 1996; Loveland et al, 1995), and the prior studies use paradigms that are not comparable to naturalistic social interactions, such as preferential looking paradigms in which the participant sees two video displays and hears one audio track.…”
