一项实验检查了快速分类中的跨模态干扰和一致性：受试者必须在 16 种条件下将复合（视觉-听觉）刺激识别为空间位置低或高（视觉判断）或音高低或高（听觉判断），每种条件组合四对可能的音调中的一对（频率差不同），以及四对可能的点对之一（位置差不同）。按位置分类和按音调分类都揭示了加纳干扰（比基线表现更差，在不相关维度上存在正交变化）和一致性效应（一致刺激组合比不一致刺激组合表现更好），但音调分类显示更多。此外，音高差的大小强烈影响按音高的分类，而不太强烈地影响按位置的分类，但位置差的大小两者都不影响。研究结果与加纳干扰和同余效应密切相关（可能源自共同来源）的观点一致，并表明不对称性可能部分取决于刺激和反应之间的维度重叠程度。
An experiment examined cross-modal interference and congruence in speeded classification: Subjects had to identify compound (visual-auditory) stimuli as either low or high in spatial position (visual judgment) of low or high in pitch (auditory judgment), in 16 conditions, each of which combined one of four possible pairs of tones, varying in frequency difference, with one of four possible pairs of dots, varying in positional difference. Both classification by position and classification by pitch revealed Garner interference (poorer performance than baseline, with orthogonal variation in the irrelevant dimension) and congruence effects (better performance with congruent than with incongruent stimulus combinations), but pitch classification showed more. Furthermore, the size of the pitch difference strongly affected classification by pitch and less strongly affected classification by position, but the size of the position difference affected neither. The findings are consistent with the view that Garner interference and congruence effects are closely related, perhaps arising from a common source, and suggest that the asymmetries could depend in part on the degree of dimensional overlap between stimuli and responses.
