This question targets the understanding of how to manipulate a motivating operation MO for socially mediated tangible reinforcement to reduce problem behavior MOs are antecedent variables that alter the effectiveness of a reinforcer and the frequency of behavior that has been reinforced by that reinforcer To abolish the MO for tangible items ie make them less desirable and thus reduce the likelihood of behavior seeking them one would implement a satiation strategy Option A describes an intervention for escapemaintained behavior eg demand fading or task completion and is a consequencebased strategy not an antecedent MO manipulation for tangibles Option B describes noncontingent reinforcement NCR for attention While NCR is an antecedent MO manipulation it is specifically targeting the MO for attention not tangible items Option C describes noncontingent reinforcement NCR for tangible items By providing free regular access to the preferred tangible every five minutes independent of the clients behavior the effectiveness of the tangible as a reinforcer is temporarily decreased due to satiation This effectively abolishes the MO for tangible access making problem behavior aimed at obtaining tangibles less likely This is an antecedent intervention directly manipulating the MO for the target function tangibles Option D describes a punishment procedure which is a consequence that aims to decrease future behavior rather than an antecedent manipulation of the MO
