In this article we examine obsessive compulsive disorder (OCD). We examine and reject two existing models of this disorder: the Dysfunctional Belief Model and the Inference‐Based Approach. Instead, we propose that the main distinctive characteristic of OCD is a hyperactive sub‐personal signal of being in error, experienced by the individual as uncertainty about his or her intentional actions (including mental actions). This signalling interacts with the anxiety sensitivities of the individual to trigger conscious checking processes, including speculations about possible harms. (...) We examine the implications of this model for the individual's capacity to control his or her thoughts. (shrink)

Illusions of personal authorship can arise when causation for an event is ambiguous, but people mentally represent an anticipated outcome and then observe a corresponding match in reality. When people do not maintain such high-level outcome representations and focus instead on low-level behavioral representations of concrete actions, illusions of personal authorship can be reduced. One condition that yields specific action plans and thereby moves focus from high-level outcomes to low-level actions is the generation of counterfactual thoughts. Hence, in the present (...) research we tested whether thinking counterfactually can reduce illusory authorship. In line with predictions, generating behavior-regulating counterfactuals reduced susceptibility to the illusion . Importantly, this only occurred when people expected to re-encounter the situation to which the counterfactuals applied . These findings extend existing research on the boundary conditions of illusory experiences of personal authorship and might hint at a relationship between the illusion and behavior regulation.
