A number of tests are commonly used in the laboratory to measure inhibitory response control in animals and humans (Table 1). This discussion cannot be comprehensive; rather, it will focus on the tasks most commonly used in the field. These include tests of action inhibition and procedures that emphasize waiting or delaying reward-seeking responses. The following section provides a description of each task and commentary on the advantages/disadvantages of each, as well as on the translational value of the measures.
