Recent developments in the study of tactile attention.

The last few years have seen a rapid growth of research on the topic of tactile attention. We review the evidence showing that attention can be directed to the tactile modality, or to the region of space where tactile stimuli are presented, in either an endogenous or exogenous (top-down or bottom-up) manner. We highlight the latest findings on the interaction between these two forms of attentional orienting in touch. We also review the latest research on tactile numerosity judgments and change detection highlighting the severe cognitive (attentional) limitations that constrain people's ability to process more complex tactile information displays. These findings are particularly important given that tactile interfaces are currently being developed for a number of different application domains
