先前的研究已经证明了成人的社会态度和模仿之间的双向关系：亲社会态度促进模仿，模仿进一步增加积极的社会态度。社会态度和社会大脑在整个青少年时期都在发展。因此，本研究的目的是测试是否亲社会的态度促进模仿在青少年组在相同的程度上在成年人组。参与者在一个混乱的句子启动任务与亲社会或非社会的话启动。然后，他们完成了一个模仿任务，其中要求参与者用食指或中指执行抬起动作，同时观察兼容的动作（例如食指反应和观察到的食指抬起）或不兼容的动作（例如食指反应和观察到的中指抬起）。在效应器预充对照条件下，观察到的手指保持静止，但将半透明绿色掩膜添加到兼容或不兼容手指。通过从不相容试验的反应时间中减去相容试验的反应时间来计算模仿效应和效应物引发效应的大小。在成人组，社会启动特别调制模仿效应：亲社会启动产生了更大的模仿效应，但不调制效应启动效应。然而，在青少年中，无论是模仿或效应启动措施，社会启动没有影响。我们认为这些结果可能的解释，包括社会大脑区域的不成熟发展和减少社会态度和模仿之间的关系在青春期的经验。
Previous studies have demonstrated a bidirectional relationship between social attitudes and imitation in adults: pro-social attitudes promote imitation, and imitation further increases positive social attitudes. Social attitudes and the social brain are developing throughout the adolescent years. Thus, the aim of this study was to test whether pro-social attitudes promote imitation in an Adolescent Group to the same extent as in an Adult Group. Participants were primed with pro-social or non-social words in a Scrambled Sentence Priming task. They then completed an Imitation task wherein participants were required to perform a lift action with either the index or middle finger, whilst observing either a compatible action (e.g. index finger response and observed index finger lift) or an incompatible action (e.g. index finger response and observed middle finger lift). In an Effector Priming control condition, observed fingers remained stationary but a semi-transparent green mask was added to either the compatible or incompatible finger. The magnitude of the Imitation Effect and Effector Priming Effect was calculated by subtracting reaction times on compatible trials from those on incompatible trials. In the Adult Group, social priming specifically modulated the Imitation Effect: pro-social priming produced a larger Imitation Effect but did not modulate the Effector Priming Effect. In adolescents, however, no effect of social priming was seen on either the Imitation or Effector Priming measures. We consider possible explanations for these results including the immature development of social brain regions and reduced experience of the relationship between social attitudes and imitation in adolescence.
