Facial electromyography
Similar to the shock condition, none of the facial
muscle sites, ipsilateral corrugator and bilateral
zygomatic, differentiated between the reward and control
trials. The possible reasons for the lack of findings
during the reward task are the same possibly explanations
for the lack of findings during the shock task; age and
gender. These reasons that age and gender possibly
contributed to the lack of significant results are discussed
above.
Verbal report ratinas
Subjects also reported more pleasantness, arousal, and
greater feelings of control during the reward anticipation
than the reward-control. Similar to the shock situation,
this illustrates that the subjects are able to perceive the
emotional tone of the situation accurately.
Additionally, in Experiment 2, subjects reported more
positive affect, and more pleasantness during the reward
compared to the control trials. There were no differences
in reported negative affect, arousal, and dominance. These
results reveal that subjects perceive the reward situation
as more positive and pleasant than the control trials.
The negative findings of the arousal and dominance
rating in Experiment 2 suggest that subjects were not as
emotionally aroused or as in control during the reward
condition in the second experiment compared the no-reward
