本研究比较了奖励预期对儿童和青少年（816岁）任务绩效的影响，使用货币和各种社会奖励。85个典型的发展中国家的儿童进行了货币激励延迟（MID）的任务。其中44人还进行了社会奖励延迟（SID-基本）任务，其中社会奖励可操作为笑脸和口头赞美。41名儿童参加了SID-plus，其中点被添加到一个象形图与书面赞美。在一项初步的验证研究中，参与者被问到他们对SID基本奖励的喜欢程度，结果表明，在MID任务和SID+任务中，奖励大小对准确性和RT都有影响，但对SID基本任务没有影响。随着假设奖励强度的增加，SID基本奖励的主观价值被评为更高。总之，尽管在验证性研究中，SID-basic中的社会奖励被儿童和青少年所喜欢，但它们对行为没有影响。只有当分数增加（SID+），预期的社会奖励影响任务绩效。因此，我们的研究结果突出了（i）可爱性和强化质量之间的差异，以及（ii）需要一个可量化的元素来奖励他们对儿童的强化。版权所有（C）2012约翰威利父子有限公司
The current study compared the effects of reward anticipation on task performance in children and adolescents (816 years old) using monetary and various social rewards. Eighty-five typically developing children undertook the Monetary Incentive Delay (MID) task. Of these 44 also undertook the Social Incentive Delay (SID-basic) task where social reward was operationalized as a smiling face and spoken compliments. Forty-one children participated in the SID-plus where points were added to a pictogram with written compliments. In a preparatory validation study participants were asked howmuch they liked the SID-basic rewards.Results showed that there was an effect of reward size on accuracy and RT in both the MID task and SID-plus, but not SID-basic. Subjective value of the SID-basic rewards was rated higher with hypothesized increasing reward intensity. In conclusion, although the social rewards in SID-basic were liked by children andadolescents in the validation study, they had no effect on the behaviour. Only when points were added (SID-plus), anticipated social reward affected task performance. Thus our results highlight (i) the difference between likeability andreinforcing quality and (ii) the need for a quantifiable element to rewards for themto be reinforcing for children.
