Abstract：
:We used identification at threshold to systematically measure binding costs in two visual modalities. We presented a conjunction of two features as a signal stimulus and concurrently measured detection and identification performance as a function of three threshold variables: duration, contrast and coherence. Discrepancies between detection and identification sensitivity functions demonstrated a consistent processing cost to visual feature binding. Our findings suggest that feature binding is indeed a genuine problem for the brain to solve. This simple paradigm can transfer across arbitrary feature combinations and is therefore suitable to use in experiments addressing mechanisms of sensory integration.

abstract：:In natural settings, our eyes tend to track approaching objects. To estimate motion, the brain should thus take account of eye movements, perhaps using retinal cues (retinal slip of static objects) or extra-retinal signals (motor commands). Previous work suggests that extra-retinal ocular vergence signals do not suppo...
