The present study examined whether popping air capsules affects studen
t's state anxiety. One group of university students were asked to pop
air capsules for 5 min. (experimental group); another group did nothin
g (the control group). Both groups were tested on the State-Trait Anxi
ety Inventory. Analyses showed that there was a difference in mean Sta
te Anxiety scores between the two groups, with the control group havin
g a lower mean than the experimental group, which was contrary to our
expectation. The findings are discussed in relation to an earlier publ
ished study of the effects of popping air capsules on changing a perso
n's mood.
