  1. For ease of interpretation, this table presents slopes of untransformed RT rather than log transformed RT. Italic values indicate significant RT slope differences across genotype by primary measure. To calculate the increase or decrease in average RT across 200 trials for individuals with a given genotype, simply multiply the slopes in the table by 200 trials. For example, for the DAT1 5R/5R genotype for the Single Dim Valid condition: mean(RT change) = 200 trials × (−0.56) msec/trial = −112 ms across 200 trials (subjects with this genotype responded more than 100 ms faster on trials at the end of the experiment than at the beginning)
