Laboratory studies have repeatedly replicated the phenomenon of exclusion responding, which has been assumed as one of the mechanisms by which children learn to relate novel words to objects or events. The present study, conducted with six children, aimed to investigate exclusion responding in a play setting, with stimuli that could be manipulated, and to verify whether the play setting would favor learning of the relationships between names and objects after a single exclusion trial. In several trials the experimenter spoke the name of a familiar toy and the child's task was to pick this toy up and throw it into a box, placed in front of the child. Three exclusion probes were interspersed among these trials (the spoken name was novel and there was a novel toy available); three other probes verified whether the relationships between the novel name and the toy had been learned. All children responded by exclusion but only one of them demonstrated learning the relationships in a single trial.
