Realism of confidence in obsessive-compulsive checkers.
The study examined whether obsessive–compulsive (OC) checkers have reduced confidence in their knowledge. OC checkers were compared with panic disorder (PD) patients and nonpatient controls using a calibration-of-knowledge procedure. Participants completed a general knowledge questionnaire, rated their confidence in each answer, and estimated the total number of correct answers.
Do smokers self-administer pure nicotine? A review of the evidence
Nicotine is almost universally believed to be the primary agent motivating tobacco smoking and the main impediment to cessation. A principal argument in support of the presumed reinforcing properties of nicotine is that smokers self-administer pure nicotine. However, the evidence for nicotine self-administration in smokers has not been critically examined.
Illusion of control and behavioral control attempts in obsessive-compulsive disorder
The present research used the illusion-of-control paradigm to examine the relationships among obsessive-compulsive disorder (OCD) symptoms, behavioral control attempts, and illusory sense of control. Participants were presented with a preprogrammed sequence of aversive and neutral visual stimuli and were encouraged to attempt to control the sequence with keyboard presses. Participants rated their perceived level of control 3 times during the task.

Obsessive-Compulsive Tendencies are Related to Seeking Proxies for Internal States in Everyday Life
In recent years we have proposed and investigated the Seeking Proxies for Internal States (SPIS) model of obsessive-compulsive disorder (OCD), which postulates that deficient access to internal states is a key feature of the disorder. According to this model, rules and rituals that often characterize people with OCD can be understood as proxies for deficiently accessible internal states. Here we compliment this earlier experimental work by examining whether reliance on proxies for internal states in everyday life is associated with OCD.
