W/F is cool. But it's not the whole story. The dipper function (https://link.springer.com/article/10.3758/APP.71.3.435 https://link.springer.com/article/10.3758/APP.71.3.435) describes a deviation from W/F behaviour that seems to represent a direct link between population neuronal activity and perception : basically, neurons respond in a sigmoidal way to increasing input and hitting the steep part of the sigmoid reduces your discrimination threshold. After a while you are past that steep bit and back to the boring old W/F regime.
