Resumen:
Domestic dogs have demonstrated striking social skills towards humans, however, there are few studiesinvestigating impulsivity with delay-choice tasks in communicative contexts. In Study 1 we introduceda novel social delay-choice task in which subjects had to choose between one human cueing an imme-diate, low quality reward and another human signaling a delayed, high quality reward. In Study 2 weevaluated the tolerance to increasing delays using social and non-social cues. We also explored if moreself-controlled dogs show any distinct behaviours during delays. Finally, we correlated all results withthe Dog Impulsivity Assessment Scale (Wright et al., 2011). In Study 1 dogs reached an average maxi-mum delay of 11.55 s. In Study 2 that average was 52.14 s with social cues and 40.2 s with non-social,but differences were not significant. Tolerance to delays showed high interindividual variation. Dogsremained mostly standing and near the delayed experimenter in the social tasks although we could notto find any distinct coping strategies. No significant correlations were found between the delay reachedand behaviours, neither with the scale. These results show the relevance of the parameters and methodsused to investigate tolerance to delay of reinforcements. More investigations are required, especially anassessment of the same subjects performing the same tasks using different contexts.
