四个研究进行了测试Ajzen（1988年，1991年）的概念，感知行为控制是否真的是一个融合的两个变量，我们称之为“感知控制”和“感知困难”。知觉控制是指人们认为某种行为的表现在他们的自愿控制之下的程度。知觉难度是指人们认为一种行为是容易还是难以执行，研究1至4的结果表明，有可能进行操纵，影响知觉控制比知觉难度，或影响知觉难度比知觉控制。研究2-4使用了各种范式来表明，人们区分被认为是感知控制和感知困难的基础的信念。最后，我们在研究5中进行了荟萃分析，以确定感知控制或感知困难对于预测行为意图和行为是否更重要。两者合计，研究结果支持知觉控制和知觉困难之间的区别，也表明，知觉困难是一个更好的预测大多数行为的意图和行为比知觉控制。
Four studies were performed to test whether Ajzen's (1988, 1991) concept of perceived behavioural control is really an amalgamation of two variables, which we term 'perceived control' and 'perceived difficulty'. Perceived control refers to the extent to which people consider the performance of a behaviour to be under their voluntary control. Perceived difficulty refers to whether people consider a behaviour to be easy or difficult to perform, Findings from Studies 1 to 4 demonstrate that it is possible to perform manipulations that affect perceived control more than perceived difficulty, or that affect perceived difficulty more than perceived control. Studies 2-4 used a variety of paradigms to show that people distinguish between beliefs that are presumed to underlie perceived control and perceived difficulty. Finally, we performed a meta-analysis in Study 5 to determine whether perceived control or perceived difficulty is more important for predicting behavioural intentions and behaviours. Taken together, the findings support the distinction between perceived control and perceived difficulty, and also suggest that perceived difficulty is a better predictor of most behavioural intentions and behaviours than is perceived control.
