Perceptual simulations are unconscious and automatic, whereas perceptual imagery is conscious and deliberate, but it is unclear how easily one can transfer perceptual information from unconscious to conscious awareness. We investigated whether it is possible to be aware of what one is mentally representing; that is, whether it is possible to consciously examine the contents of a perceptual simu...

Recent neuroimaging research has shown that perceptual and conceptual processing share a common, modality-specific neural substrate, while work on modality switching costs shows that they appear to share some of the same attentional mechanisms. In two experiments, we employed a modality detection task that displayed modality-specific object properties (e.g., shrill, warm, crimson) for extremely...

The majority of task-switching research has focused on shifting attention between multiple tasks in the same perceptual modality (i.e., visual) within a single task domain. However, typical environments are not unisensory, and typical response decisions often involve multiple task domains. This study examines multisensory task-switching costs and the interactions of several variables, including...

We examined whether words studied in one modality (visual or auditory) would prime performance in the opposite modality in five different perceptual implicit memory tests: auditory perceptual identification, auditory stem completion, visual perceptual identification, visual stem completion, and visual fragment completion. Significant transfer across modality was observed in all five tasks. Howe...

Verifying different sensory modality properties for concepts results in a processing cost known as the modality-switch effect. It has been argued that this cognitive cost is the result of a perceptual simulation. This paper extends this argument and reports an experiment investigating whether the effect is the result of an activation of sensory information which can also be triggered by percept...

Sensory substitution devices provide through an unusual sensory modality (the substituting modality, e.g., audition) access to features of the world that are normally accessed through another sensory modality (the substituted modality, e.g., vision). In this article, we address the question of which sensory modality the acquired perception belongs to. We have recourse to the four traditional cr...
