In the context of processing unwanted thoughts, memories or emotion, the main cognitive goal of individual is to suppress such undesired contents by keeping them out of consciousness. This paper provides an overview of empirical and clinical studies as well as theoretical models regarding suppression mechanisms of unwanted contents. Our main focus was to clarify controversial aspects related to efficiency of suppression in regulating behaviour. In particular, we emphasised significance of metacognition for suppression claiming that successful suppression requires concordant combination of both control and monitoring processes.
