^aLogPPS = log of the sum of play, pause, and seek clicks made while viewing the Cancer Genetics Education Material

^bTime = number of minutes viewing the Cancer Genetics Education Modules

^cTGJASL-R: ASL Grammar Judgement Task. >0.5–1 reflects increasing grammatical accuracy; 0.5 reflects random guessing; <0.5 reflects systematic bias

^dself-rated on scale of 0 (low) – 10 (high)

^ebased on 25 true/false items (range 0–25)

^fr is the Pearson’s correlation coefficient
