Introduction Normally, needing to urinate does not bring about positive emotions, as individuals can describe it to be quite uncomfortable. Although the sensation may be unpleasant, a full bladder can feel great, for liars. The Inhibitory Spillover Effect shows individuals with a full bladder resulted in better lying. The lying and deception is correlated with inhibition, a central cognitive mechanism. Typically, lying and a full bladder are not associated with one another, but both effect inhibitory abilities. When lying, individuals use more brainwork, as they have to think of the truth, keep it in mind, while placing layers of lies on top. Compared to telling the truth, areas in the prefrontal cortex and the anterior cingulate cortex operate greater. There is also more activity in the front and cingulate regions (p.113). Experiments were done in order to determine whether or not a full bladder does actually help create better liars (p. 114). Predictions were made that the high inhibition lying individuals with a full bladder would have better control of their behavioral cues. It was also predicted that third-party observers would not be able to easily detect the full …show more content…
These participants were questioned on their opinions, since lying about opinions tend to be more difficult. The participants consisted of twenty-two university students, both male and female. In the inhibitory task, the participants took an opinion questionnaire and were told a cover story. Then, those in the high control condition drank 700 ml., and those in the low condition drank 50 ml. They were given the option to use the restroom or they would not be able to use it until the study was completed. The participants then waited forty-five minutes for the interview. In the deception task, the interviewees were asked questions about topics they felt strongly about, which would make lying
