Description
The brain integrates signals from multiple modalities to provide a reliable estimate of environmental events. A temporally cluttered environment presents a challenge for sensory integration because of the risk of misbinding, yet it also provides scope for cross-modal binding to greatly enhance performance by highlighting multimodal events. We present a tactile search task in which fingertips received pulsed vibrations and participants identified which finger was stimulated in synchrony with an auditory signal. Results showed that performance for identifying the target finger was impaired when other fingers were stimulated, even though all fingers were stimulated sequentially. When the number of fingers vibrated was fixed, we found that both spatial and temporal factors constrained performance, because events occurring close to the target vibration in either space or time reduced accuracy. When tactile search was …
