This article investigates how children leverage intonational and gestural cues to an individual’s belief state through unimodal (intonation-only or facial gesture-only) and multimodal (intonation + facial gesture) cues. A total of 187 preschoolers (ages 3–5) participated in a disbelief comprehension task and were assessed for Theory of Mind (ToM) ability using a false belief task. Significant predictors included age, condition and success on the ToM task. Performance improved with age, and was significantly better for the multimodal condition compared to both unimodal conditions, suggesting that even though unimodal cues were useful to children, the presence of reinforcing information for the multimodal condition was more effective for detecting disbelief. However, results also point to the development of intonational and gestural comprehension in tandem. Children that passed the ToM task significantly outperformed those that failed it for all conditions, showing that children who can attribute a false belief to another individual may more readily access these intonational and gestural cues.

Communication is essential during social interactions including animal conflicts and it is often a complex process involving multiple sensory channels or modalities. To better understand how different modalities interact during communication, it is fundamental to study the behavioural responses to both the composite multimodal signal and each unimodal component with adequate experimental protocols. Here we test how an African cichlid, which communicates with multiple senses, responds to different sensory stimuli in a social relevant scenario. We tested Maylandia zebra males with isolated chemical (urine or holding water coming both from dominant males), visual (real opponent or video playback) and acoustic (agonistic sounds) cues during agonistic interactions. We showed that (1) these fish relied mostly on the visual modality, showing increased aggressiveness in response to the sight of a real contestant but no responses to urine or agonistic sounds presented separately, (2) video playback in our study did not appear appropriate to test the visual modality and needs more technical prospecting, (3) holding water provoked territorial behaviours and seems to be promising for the investigation into the role of the chemical channel in this species. Our findings suggest that unimodal signals are non-redundant but how different sensory modalities interplay during communication remains largely unknown in fish.

1. The synthesis of information from different sensory modalities in the superior colliculus is an important precursor of attentive and orientation behavior. 2. This integration of multisensory information is critically dependent on inputs from a small area of association cortex, the anterior ectosylvian sulcus. Removal of these corticotectal influences can have a remarkably specific effect: it can eliminate multisensory integration in superior colliculus neurons while leaving their responses to unimodal cues intact. 3. Apparently, some of the associative functions of cortex are accomplished via its target neurons in the midbrain.
