What is some experimental evidence to support the view that mental representations are multimodal?

''Cakes are not only seen, they are also tasted, smelled, touched, and acted on; perhaps the one modality by which cakes are not experienced much is sound''. It has be found that throughout the brain, convergence zones integrate category knowledge in various ways, such that category knowledge captures the multimodal character of category members. Therefore we can say that the different features across modalities become integrated and thus can be retrieved together. If we take the cake as an example it is easy to image how it looks, tastes, smells, feels, and how we eat it. In that way the higher order convergence zones are activated.

Behavioural evidence suggests that mental representations are multimodal. ''The visual mechanisms that process occlusion, size, shape, orientation, and similarity have all been shown to affect category processing''. It turns out that whenever participants have to switch modalities to verify a property, it takes longer than when they do not have to switch modalities.

Neural evidence also suggests that mental representations are multimodal.
-Thinking about performing actions on object=motor areas activated.
-When participant retrieve an object's motion properties=regions in the posterior temporal gyrus that overlap motion processing areas in vision become active.
-When participants retrieve sounds of objects=auditory brain area is activated.
-Access knowledge of foods=gustatory areas activated.

It has been said that for example category knowledge about color, shape and motion ''is processed near the respective brain areas that process this information in visual perception''.
