Overview of models and their relationships. A. Blocked input 2.0 as in Logan et al. (2015). B. Blocked input 3.0 integrates aspects of DINASAUR into blocked input 2.0 in an attempt to capture the signal-ignore condition. Its inputs are split into two conceptually different streams: A fast and transient drive tied to visual onsets (exogenous) and a slower sustained drive tied to instructions (endogenous). C. 200N-DINASAUR is a map of fully interconnected neurons representing part of the left, central, and right visual fields, invented to capture simplified SC dynamics. The temporal dynamics of its exogenous signals (quick growth and exponential decay) is a key factor for creating sharp dips and quick recovery.
