condition was within-subject factors. There were no

significant main effects or interactions. The overall means

for each group are as follows: (LHD mean=1.70, sd=3.70; LH

NCS mean=1.61, sd=2.88; RHD mean=2.02, sd=4.10; RH NCS

mean=1.90, sd=3.47). The ANOVA tables, Table C-14, is

presented in Appendix C.

 The same type of repeated measures analyses with group

as the between subjects factor and condition and block as

the within subject factors was used to examine D2. Analysis

of D2 revealed that there were no significant main effects.

There was, however, a significant block by group interaction

[F(9,43) = 2.34, P < .05] See Table C-15 in Appendix C

for details of the ANOVA table. The means for each group

for each block are presented below.

 To further examine the block by group interaction,

separate ANOVAs were performed for each block. Group was

the between subjects factor. There were no significant
