They suggested that environmental information is processed by various modality-specific sensory registers before it is combined into a single, modality-independent, or more formally amodal, percept and transferred into a short-term store. In their seminal work, Atkinson and Shiffrin (1968) devised a model for the flow of information in human memory, which subsequently became known as the modal model. Working Memory and the Multisensory Brain We will argue that a multisensory approach to the study of working memory is indispensable to achieve a realistic understanding of how working memory processes maintain and manipulate information. To do so, we will focus on reviewing working memory research conducted from a multisensory perspective. The aim of this paper is to discuss the current status of research on multisensory processing and the implications of these findings for our theoretical understanding of working memory. (2010) we will use the terms “modality-specific” or “cross-modal” when describing the properties of objects and “unisensory” or “multisensory” when referring to neural or behavioral processes associated with a single or multiple sensory modalities. In accordance with the suggestions of Stein et al. Information from different sensory modalities can also be combined into a single multisensory event, a process that is referred to as multisensory integration ( Stein et al., 2010). This implies that information from one modality can influence information processing in another modality. Multisensory processing refers to the interaction of signals arriving nearly simultaneously from different sensory modalities. For instance, in working memory, research has focused on resolving whether information is memorized in the form of separate, modality or domain specific representations ( Baddeley and Hitch, 1974 Schneider and Detweiler, 1988), or as integrated representations ( Atkinson and Shiffrin, 1968 Cowan, 2001). ![]() While we are beginning to understand how our senses interact at various stages of processing (for an overview see, e.g., Wallace et al., 1993 Beauchamp, 2005 Ghazanfar and Schroeder, 2006 Stein and Stanford, 2008 Klemen and Chambers, 2012) it is still heavily debated whether the higher-order mental representations that are derived from these sensory inputs still contain modality- specific information or not. Even though this experience is mostly multisensory, that is, we receive information from multiple senses simultaneously, psychological research has primarily focused on studying our senses in isolation. In everyday life we experience a continuous stream of information that we perceive through sight, sound, smell, taste, and touch. ![]() We argue that a multisensory approach to the study of working memory is indispensable to achieve a realistic understanding of how working memory processes maintain and manipulate information.Ī Multisensory Perspective of Working Memory To do so, we focus on reviewing working memory research conducted from a multisensory perspective, and discuss the relation between working memory, attention, and multisensory processing in the context of the predictive coding framework. We discuss the current status of research on multisensory processing and the implications of these findings on our theoretical understanding of working memory. These interactions raise questions regarding the manner in which multisensory information is maintained in working memory. Results from the multisensory processing literature make it clear that the senses interact on a more intimate manner than previously assumed.
