- Note. – The average parameters of the equation. Influence = ce-λt+ b representing the delay-of-reinforcement gradients for every rat. The parameters of each rat were weighted by the goodness of fit of that model to their data. The semi-interquartile ranges of the parameters are in parentheses. All sessions testing FI< 300s and the last 21 sessions testing FI 300 s were used for analyses of influence functions.
