Abstract We provide two characterizations, one axiomatic and the other neuro-computational, of dependence choice probabilities on deadlines, within widely used softmax representation $$\begin{align*} p_{t}\left( a,A\right) =\dfrac{e^{\frac{u\left( a\right) }{\lambda\left( t\right) }+\alpha\left( }}{\sum_{b\in A}e^{\frac{u\left( b\right) }}, \end{align*}$$ where $p_{t}\left( $ is probability tha...
