C Correct answer
Explanation

Speed of processing in cognitive psychology is measured by brain activity following stimulus exposure, typically using event-related potentials (ERPs) or reaction time tasks. The number of mistakes (A) measures accuracy not speed. Options B and D refer to specific motor tasks but not standardized processing speed measures. Brain activity measurement (C) is the most accurate general description of processing speed assessment techniques.
