The Effect of Thought Detection on Anxiety Responses Page: 4

                                
significant differences between the groups in heart rate and
blood pressure, although the means of these measures were
nonsignificantly lower on the post measures for the experi-
mental group following the baseline period.   The control
group's scores on these measures were nonsignificantly greater
than the pre-measure scores for that group. There were no
statistically significant differences revealed in the Taylor
Manifest Anxiety scores between the groups.
The statistical analysis for determining the effects of
contingent reinforcement on the daily percentage of anxious
thoughts, comparing the experimental with the control group,
revealed no significant differences between the groups.
Although the group statistical analyses would tend to evoke
a rejection of all differences between the groups in detec-
tion responses, when the data trends of individuals were
inspected, that inspection suggested further analysis should
be undertaken. Accordingly, the data of individuals were
subjected to the time-series analysis. The analysis revealed
significant intervention effects for three of the five members
of the experimental group. Two members of the control group
also made significant shifts in the direction of a decrement
in the frequency of anxious thoughts. As two of the five
subjects with significant data were control subjects and had
not received contingent reinforcement, it is not likely that
reinforcement could be singularly credited with the signif-
icance found for each of the five subjects.
