Dynamic and structured action bias masks learned task contingencies early in learning
Ziyi Zhu,Céline Drieu,Kishore Kuchibhotla · COSYNE 2022
Learning is not only the acquisition of knowledge, but also the ability to express that knowledge when needed. Previous work using non-reinforced probe trials showed that animals exhibit complete acquisition of stimulus-action associations far before they express them under reinforcement. Why do animals exhibit this gap in performance between acquisition and expression despite already acquiring the stimulus-action associations? Early in learning, animals may (1) exhibit motor biases that they slowly learn to suppress, (2) continue to explore different choice alternatives, or (3) base decisions
