Pavlovian acquisition data. Panel A: Number of Pavlovian training trials needed before mice met an acquisition criterion (i.e., the CS alone reliably evoked the conditioned response) plotted as a function of the number of NS→US trials completed per session (Gallistel & Papachristos, 2020). Panel B: Conditioned response rate in a rat autoshaping experiment (Papini & Dudley, 1993). In rats completing one trial per session, the NS evoked conditioned responding at above baseline levels by the 4th trial block. For rats in the 20-trials per session group, the NS was not yet evoking conditioned responding after 40 training trials. Panel C: Sessions to acquisition across groups that acquired the CS function.
