综合预期研究表明，在参与者必须做出意想不到的运动反应的试验中，空间提示效应会降低。在前两个实验中，研究了预期效应降低的范围。对可能反应的预先了解与模态提示、对象提示和任务提示结合在逐个试验的程序中。在目标要求意外响应的试验中，模态提示的效果会降低。然而，对象提示的效果以及任务提示的效果不受响应提示的影响。比较实验表明，不同的实验使用了不同类型的线索。为了测试线索类型对期望相互作用的影响，第三个实验将空间线索与反应线索结合起来。当使用综合线索通过箭头提示可能的目标位置并通过箭头提示可能的响应时，在具有意外响应的试验中空间提示效应会降低。然而，当使用由提示响应的单词和提示目标位置的箭头组成的单独提示时，空间提示效果仍然不受响应提示的影响。根据调整后的预期模型，建议考虑线索之间的关系对组合预期的调节。
Studies of combined expectancies have shown that spatial cueing effects are reduced on trials on which participants have to respond with an unexpected motor response. In the first two experiments the range of reduced expectancy effects is examined. Advance knowledge of the likely response was combined in a trial-by-trial procedure with modality cueing, object cueing, and task cueing. Effects of modality cueing were reduced on trials on which the target requested an unexpected response. However, effects of object cueing as well as effects of task cueing were unaffected by response cueing. Comparing experiments revealed that different types of cues were used in different experiments. To test the effect of type of cue on the interaction of expectancies the third experiment combined spatial cueing with response cueing. When integrated cues were used that cued the likely target location by an arrow and the likely response by an arrow too, spatial cueing effects were reduced on trials with unexpected responses. However, spatial cueing effects remained unaffected by response cueing when separated cues were used consisting in a word cueing the response and an arrow cueing target location. An account for the modulation of combined expectancies by the relation between cues is suggested in terms of the adjusted expectancy model.
