Quantity can be expressed in a variety of ways and at dif-ferent levels of precision. One factor that influences numer-ical description of elements in a visual scene is how long thescene is observed. We extend a previous incremental modelof numerical perception to model quantified description undertime constraints. Our extended model predicts that as presen-tation duration decreases and as the quantity of items to beenumerated increases, the frequency of inexact quantifiers willincrease. We conducted two human subject elicitation stud-ies to test these predictions. Our findings were consistent withour model’s predictions. Additionally, we demonstrate that ournovel model of incremental numerical perception and quanti-fied description closely predicts the precise proportion of exactnumerical responses generated by in these experiments.
