title: Negative transfer in human associative learning.
abstract: Models of attentional allocation in associative learning are typically structured according to one of two guiding principles: the predictiveness principle, which posits that attention is paid to cues that have reliably predicted an outcome in the past, or the uncertainty principle, which states that attention is paid to cues about which little is known. Both principles are well supported by studies of animals. However, in studies of human learning, there is very little direct empirical support for the uncertainty principle. In the study reported here, we addressed this gap by investigating negative transfer, a phenomenon that may provide unique support for the uncertainty principle. In two human learning experiments using an allergist task, we replicated the primary findings of previous research on animal learning. We believe that these data provide the first direct evidence for the uncertainty principle in human associative learning.
