Cues that signal motivationally significant consequences can elevate responding and bias choice. A task known as Pavlovian-to-instrumental transfer (PIT) has been used to assess the influence of these cues on independently trained responses and to study the effect of drug-related and food-related cues on behavior in adult populations, but it has not yet been employed in children. This study aimed to develop a simple computer task to study PIT in children. Participants, aged 7-11 years, observed a screen in which different pairings of distinct cartoon images and specific outcomes were presented (images of foods and drinks in Experiment 1 and images of pets in Experiment 2). After this, the participants pressed two keys, each consistently reinforced with one of the two outcomes. Finally, the children pressed both keys in the absence of any outcome, and each cartoon image was presented periodically so that the effect of these cues on behavior could be measured. Experiment 1 showed that the cartoons' presentations biased responding toward the key that was trained with the same outcome as the cartoon being presented, that is, outcome-specific PIT. Experiment 2 replicated this finding and also showed that a cartoon trained with an outcome different from that reinforcing the responses elevated performance of both responses relative to a cartoon that was not paired with any outcome in training, that is, general PIT. These findings are consistent with those reported in the adult population and might be a useful tool to study the early development of maladaptive behaviors.
