title: Exploring the boundaries of memory distrust from repeated checking: increasing external validity and examining thresholds.
abstract: Checking behavior is among the most common forms of compulsions in OCD. Recent research suggests that repeated checking decreases memory confidence, and supports theoretical models of how repeated checking is maintained. The current paper presents findings from two studies exploring the boundaries of memory distrust from repeated checking. Results of study 1 show that repeated checking of a real stove decreases memory confidence, vividness, and detail (i.e., metamemory), and leads to a greater reliance on knowing as a source of memory, without meaningfully altering memory accuracy. Results of study 2 suggest that these changes in metamemory are observed after performing a relatively low number of checks on one occasion. The findings are considered within the context of theoretical models of checking and future directions are delineated.
