“…the colour and weight of an object), and object information is either merged based on sensory reliability [ 42 ] or based on incidental or statistical learning of crossmodal associations from the environment [ 43 ]. Furthermore, prior knowledge can facilitate the binding of redundant cues due to the allocation of selective attention during encoding [ 44 ]. These differences—that is, whether crossmodal information is integrated based on cue redundancy or statistical learning—suggest that there may be separate mechanisms underpinning the formation of multisensory categories, and that each may be attributed to early or late integration in the brain (as we discuss in detail in §5).…”

Although object categorization is a fundamental cognitive ability, it is also a complex process going beyond the perception and organization of sensory stimulation. Here we review existing evidence about how the human brain acquires and organizes multisensory inputs into object representations that may lead to conceptual knowledge in memory. We first focus on evidence for two processes on object perception, multisensory integration of redundant information (e.g. seeing and feeling a shape) and crossmodal, statistical learning of complementary information (e.g. the ‘moo’ sound of a cow and its visual shape). For both processes, the importance attributed to each sensory input in constructing a multisensory representation of an object depends on the working range of the specific sensory modality, the relative reliability or distinctiveness of the encoded information and top-down predictions. Moreover, apart from sensory-driven influences on perception, the acquisition of featural information across modalities can affect semantic memory and, in turn, influence category decisions. In sum, we argue that both multisensory processes independently constrain the formation of object categories across the lifespan, possibly through early and late integration mechanisms, respectively, to allow us to efficiently achieve the everyday, but remarkable, ability of recognizing objects. This article is part of the theme issue ‘Decision and control processes in multisensory perception’.
