Stable personality dispositions, like motives, are often assumed to exert a direct, stable impact on behavior. This also applies to the explicit achievement motive, which is supposed to influence the behavior that individuals select and how strongly they engage in it. Drawing on motivational intensity theory, we demonstrated in two studies that explicit achievement motive strength only predicted exerted force in a hand grip task if task difficulty was unclear. If task difficulty was clear, explicit achievement motive strength did not influence exerted force. Our findings suggest that the availability of information about the difficulty of motive satisfaction moderates the impact of the explicit achievement motive on behavior.
稳定的人格特质，如动机，通常被认为会对行为产生直接、稳定的影响。这也适用于明确的成就动机，它应该会影响个人选择的行为以及他们对其投入的程度。基于动机强度理论，我们在两项研究中表明，只有在任务难度不明确的情况下，明确的成就动机强度才会预测手掌握力任务中的施力大小。如果任务难度明确，明确的成就动机强度不会影响施力大小。我们的研究结果表明，有关动机满足难度的信息的可获得性调节了明确的成就动机对行为的影响。
