Two propositions connected by and have the same truth-value, irrespective of the order of the conjuncts. However, in a sentence like “I put my socks and shoes on” it becomes obvious that the order of the conjuncts affects the meaning of the sentence. This study concerns the contribution of pragmatics to and by implicit enrichment to and then or and thus. It includes three experiments that investigate and-enrichment in adults and children. Nine five-line stories concerning everyday events were used. After each story the participants were to respond “yes” or “no” to a statement which referred to two events that occurred in the story, conjoined with and. In the critical statement, the two events were presented in the inverse order to which they had occurred. The results show no general developmental effect but awareness of the task plays a critical role for and-enrichment production. Ten-year-olds enrich and to the same extent as adults when no efforts are made to mask the intention behind the task. However, when a more spontaneous response is captured by masking the purpose of the task children respond more logically. There are no clear evidence that and-enrichment is affected by the cognitive demands of the task.
