在人类和动物中的一个强有力的发现是，混合暴露于2个相似的刺激（AX/BX）比暴露于2个单独的块（CX_DX）中的2个同样相似的刺激（混合阻断效应）在测试中更好地区分这些刺激。这种混合-阻断效应可能是间隔练习优于集中练习的一个例子;在混合但不是阻断的暴露方案中，给定刺激的每次呈现（例如，AX）通过其伙伴（BX）的表示与下一个分隔开。两个人类参与者的实验复制了混合阻断效应，并表明这种效应不是由于暴露试验的间隔。结合联想学习和记忆理论，提出了混合阻断效应的产生机制。
A robust finding in humans and animals is that intermixed exposure to 2 similar stimuli (AX/BX) results in better discriminability of those stimuli on test than does exposure to 2 equally similar stimuli in 2 separate blocks (CX_DX)--the intermixed-blocked effect. This intermixed-blocked effect may be an example of the superiority of spaced over massed practice; in the intermixed, but not the blocked exposure regime, each presentation of a given stimulus (e.g., AX) is separated from the next by the presentation of its partner (BX). Two experiments with human participants replicated the intermixed-blocked effect and showed that the effect was not due to the spacing of exposure trials. A mechanism for the intermixed-blocked effect is proposed, which combines theories from associative learning and memory.
