Early weighting in MT impacts psychophysical weighting. (a) Schematic of a model psychophysical observer based on model MT input. The stimulus is converted into model MT outputs for two pools of MT neurons, which are then integrated and compared to predict choices. (b) Psychometric function for the model observer (purple) overlaid with the data (black) (n=22,838 trials). Error bars are ± s.e.m. (c) Temporal weighting for an observer based on perfect integration of simulated realistic MT neurons (purple) overlaid with the data (black). Dashed lines indicate ±1 s.e.m.
