1. A system for assessing a reaction performance of a user engaging with an interactive digital program based at least in part on biopotentials detected at an external surface of a skin portion of the user, the system comprising:
one or more processors; and
a wearable device configured to be worn by the user, the wearable device comprising:
one or more electrodes configured to be disposed adjacent to an external surface of the skin portion, wherein the skin portion is disposed at a body portion comprising peripheral nerve tissue that is biologically coupled to a central nervous system of the user;
wherein the system is configured to:
obtain, using the plurality of electrodes, biopotential signals generated at least in part by the peripheral nerve tissue;
determine a first timestamp, the first timestamp indicating a first time at which a stimulus condition based on a graphical display is presented to the user during the interactive digital program;
determine a second timestamp, the second timestamp indicating a second time at which the biopotential signals indicate an intention by the user to perform a responsive action in response to the stimulus condition presented to the user during the interactive digital program; and
determine a subject response time for the user based at least on an amount of time between the first timestamp and the second timestamp.
