From: Assessing the quality of supplementary sensory feedback using the crossmodal congruency task
Crossmodal congruency effect framework. Participants rapidly select the target feedback (e.g. vibration shown in red). The target feedback is presented concurrently with distractor visual feedback (green LED). Feedback can be presented congruently, i.e. visual and target feedback collocated in the top row, or incongruently with mismatched visual and target feedback. The crossmodal congruency effect (CCE) score is the difference between the response time to congruent and incongruent stimuli. The cross-modal effect can also manifest as an elevated error rate during incongruent trials25. Spatial separation, the physical distance between the two paired sensory percepts, can be varied, and is indicated with the rulers.
