NCS=-.178, sd=.747; RHD= -.467, sd=.853; RH NCS= -.370,

1.021.

 As mentioned above D1, Al, and D2 data were analyzed

separately using repeated measures ANOVAs with group as the

between subject factor and condition (reward, no-reward) and

block (1 to 4) as the within subject factors. There were no

significant main effects or interactions for any of the

three variables. ANOVA tables for these three variables are

in Appendix C, Tables C-41, C-42, and C-43. A table of

means for each of the three variables by group is presented

below.

Table 4-5 Means and Standard Deviations of Dl, Al, and D2
for the Reward Condition

 D1 Al D2

 LHD -2.46 (3.56) 1.71 (3.82) -1.05 (3.83)

 LH NCS -1.36 (1.75) 1.06 (2.16) -.32 (2.23)

 RHD -1.57 (2.24) .95 (2.52) -.69 (2.38)

 RH NCS -2.22 (2.90) 1.70 (3.87) -1.27 (2.93)

 To sum, overall heart rate along with Dl, Al, and D2

were not significantly different between the reward and

reward-control trials. Additionally, there were no group

differences in overall heart rate or Dl, Al, and D2.

 Skin conductance. Similar to the shock task,

percentage of SCR responses and recorded range corrected SCR

were analyzed separately. Also, one RHD subject was

excluded from analyses due to corrupt data.
