Table 1 Definitions of key terms from cognitive neuroscience studies to describe concepts relating to multisensory processing, as outlined by Stein et al., 2010

From: Multisensory inclusive design with sensory substitution

Term Definition Property the concept is attributed to
Unisensory Any neural or behavioural process associated with a single sense Neural or behavioural responses
Multisensory Any neural or behavioural process associated with multiple senses Neural or behavioural responses
Cross-modal display mode A display with multiple display modes to channel sensory information of different origins Display type
Multisensory integration A specific multisensory processing where redundant sensory information is optimally integrated to result in a multisensory response significantly different than their unisensory correspondence Neural or behavioural response
Multisensory combination A specific multisensory process where complementary sensory information is combined to result in a more accurate estimate of the sensory source Neural or behavioural response
Modality-specific The sensory information from a source that results in a unisensory response The sensory source
Cross-modal The sensory information from a source that results in a multisensory response The sensory source
Spatial coincidence The spatial overlap between two or more cross-modal stimuli of the same sensory source The sensory source
Temporal coincidence The temporal overlap between two or more cross-modal stimuli of the same sensory source The sensory source
Redundancy The reliability of spatially and temporally overlapping cross-modal stimuli of the same sensory source The sensory source, and the neural and behavioural response
Complementary Sensory information from the same sensory source that is not spatially or temporally overlapping The sensory source, and the neural and behavioural response
Inverse effectiveness The influence of reliability on cross-modal cues in multisensory processing Neural or behavioural response
Cross-modal correspondence Associations between different sensory forms Neural or behavioural response
