Groups of 7 1/2-month-old infants heard 1 of 8 episodes consisting of no, slight, moderate, or a large discrepancy between a habituated standard and a transformed auditory stimulus. The patterns of cardiac deceleration, regarded as an index of attention supported the hypothesis that attentiveness is an inverted-U function of the degree of discrepancy between stimulus event and schema.
7个半月大的婴儿被分成若干组，每组婴儿听8个情节中的1个，这些情节包括习惯化标准与转换后的听觉刺激之间无差异、有轻微差异、有中等差异或有很大差异。心脏减速模式被视为注意力指标，这一模式支持了以下假设：注意力是刺激事件与图式之间差异程度的倒U型函数。
