The effects of global harmonic contexts on expectancy formation were studied in a set of three experiments. Eight-chord sequences were presented to subjects. Expectations for the last chord were varied by manipulating the harmonic context created by the first six: in one context, the last chord was part of an authentic cadence (V-I), whereas in the other, it was a fourth harmonic degree following a full cadence (I-IV). Given this change in harmonic function, the last chord was assumed to be more expected in the former context, all the other local parameters being held constant. The effect of global context on expectancy formation was supported by the fact that subjects reported a lower degree of completion for sequences ending on an unexpected chord (Experiment 1), took longer to decide whether the last chord belonged to the sequence when the last chord was unexpected (Experiment 2), and took longer to decide whether the last chord was consonant or dissonant when it was unexpected (Experiment 3). These results are discussed with reference to current models of tonal cognition.
在一组三个实验中研究了全局和声背景对期望形成的影响。向受试者呈现八和弦序列。通过操纵前六个和弦所创造的和声背景来改变对最后一个和弦的期望：在一种背景下，最后一个和弦是正格终止（V-I）的一部分，而在另一种背景下，它是完全终止（I-IV）之后的四级和弦。考虑到和声功能的这种变化，假设在前一种背景下最后一个和弦更易被预期，所有其他局部参数保持不变。全局背景对期望形成的影响得到以下事实的支持：受试者报告以意外和弦结束的序列的完成度较低（实验1），当最后一个和弦意外时，判断最后一个和弦是否属于该序列花费的时间更长（实验2），并且当最后一个和弦意外时，判断其是协和还是不协和花费的时间更长（实验3）。参照当前的调性认知模型对这些结果进行了讨论。
