Latency time (Copy)
Total latency time in copy condition
This variable is only available in MARS and in Clinical Core.
Latency time in the copy condition is the sum total of all inter-digit, pre- and post-first hand latencies during the copy condition. Data are captured during the digital Clock Drawing Test (dCDT) using digital pen technology. See the digital pen device category description for more information.
Participants are asked to "draw the face of a clock with all of the numbers and set the hands to 10 after 11."
Latency time during the copy condition is expressed in seconds.
