增强英语:Reinforcement),或称强化,是行为主义心理学中的一个重要概念,是关于理解和修正人的行为的一种学说。

科学研究发现,人类或动物为达到某种目的,会于所处的环境下采取特定行为;当这种行为带来的某种反应或后果对他有利时, 这种行为就会在以后重复出现,而该结果就称为“增强物”;反之亦然,当其行为会对他带来不利时,这种行为就自然减弱或消失,个体对行为结果所产生的后续反应,就是以操作性条件反射进行的。而由于“增强物”的适时出现,增加了个体以后在相同情形下重复这种行为的机率,这表示“增强物”对于个体的反应起了强化作用。此种强化作用,即称之为「增强」。

In behavioral psychology, reinforcement is a consequence that will strengthen an organism's future behavior whenever that behavior is preceded by a specific antecedent stimulus. This strengthening effect may be measured as a higher frequency of behavior (e.g., pulling a lever more frequently), longer duration (e.g., pulling a lever for longer periods of time), greater magnitude (e.g., pulling a lever with greater force), or shorter latency (e.g., pulling a lever more quickly following the antecedent stimulus).
