Self-touch serves for regulation of both hyper- and hypoarousal. It remains unclear if different forms of self-touch occur in different contexts, and if the regulatory mechanisms are learned or innate. The authors describe forms and context of self-touch, and explore age differences in stress processing. They analyzed hand movements of 10 pre- and 10 postadolescent girls in low-stress and high-stress settings and found 3 forms of self-touch. In postadolescent participants, self-touch 2 (irregular structure, rhythmical, medium intensity) and 3 (phasic structure, single accent, medium intensity) were used for self-regulation, whereas self-touch 1 (irregular structure, single accent, low intensity) had conversational reasons. Increasing immobility might represent the inward focus of stressed participants that tried to focus on the task. No differences were found for preadolescent participants. Differences between pre- and postadolescent participants might be due to brain development during adolescence.
自我触摸有助于调节过度兴奋和兴奋不足。目前尚不清楚不同形式的自我触摸是否在不同情境中出现，以及调节机制是后天习得还是先天固有。作者描述了自我触摸的形式和情境，并探讨了压力处理过程中的年龄差异。他们分析了10名青春期前和10名青春期后的女孩在低压力和高压力环境下的手部动作，发现了3种自我触摸形式。在青春期后的参与者中，自我触摸2（不规则结构、有节奏、中等强度）和自我触摸3（阶段性结构、单一重音、中等强度）用于自我调节，而自我触摸1（不规则结构、单一重音、低强度）则有交流方面的原因。静止不动增加可能代表着压力大的参与者向内聚焦，试图专注于任务。青春期前的参与者未发现差异。青春期前和青春期后参与者之间的差异可能是由于青春期大脑发育所致。
