The present study explored whether glucose rinsing has any effect on mood changes, particularly in positive affect (PA) and negative affect (NA) after engaging in prosocial behavior. The study used a 2 (Glucose Rinse vs. Non-Glucose Rinse) x 2 (Autonomous Helping vs. Controlled Helping) between-subjects design. Participants’ mood and wellbeing changes were measured before and after the experiment. In the study, participants are given a 5-minute perceptual vigilance task, which they had to cancel out all the e’s in the passage to deplete self control. After which, the participant was asked to rinse with a glucose or non-glucose solution depending on which condition they were assigned to prior to the study. After that, they were given 7-8 minutes of rest time in which, coincidentally, a confederate enters the experimenter room to ask the participant to engage in a spontaneous helping task. Results showed that participants in the Non-Glucose condition had greater post NA regardless of whether they had an autonomous or controlled motive to help. Moreover, there is also a significant interaction between glucose rinsing and helping motive such that in autonomous helping situations, a non-glucose rinse will be more effective than a glucose rinse in enhancing PA after helping. Whereas, in controlled helping situations, a glucose rinse will be more effective than a non-glucose rinse in enhancing PA after helping. These findings suggest that the type of rinse (glucose vs. non-glucose) work differently with regards to affect changes in different helping motives. Limitations and future research implications are also discussed.
