## Abstract

In response to determining that performance data of device operation by an operating user meets a safety requirement, embodiments determine a degree of deviation of a performance data value from a baseline pattern of good performance values defined for the user; in response to determining that the degree of deviation of the operating data value meets a cognitive assessment threshold, administer a cognitive aptitude test challenge to the user selected from baseline aptitude profile data of challenges previously responded to by the user; and execute a corrective action that reduces a risk of loss in response to determining that a degree of deviation of a value of a response provided by the user to the cognitive test challenge from a performance metric value of the baseline aptitude profile data meets a threshold cognitive assessment threshold.
