Decision making by humans in a behavioral task: do humans, like pigeons, show suboptimal choice?

abstract：:Delay of reinforcement is generally thought to be inversely correlated with speed of acquisition. However, in the case of simultaneous discrimination learning, in which choice results in immediate reinforcement, delay of reinforcement can improve acquisition. For example, in the ephemeral reward task, animals are give...

In two experiments, we asked whether sensory preconditioning facilitates the transfer of deferred imitation.
