This study dealt with the effect of low-level noise and high-level noise, of white noise and varied noise, and of high manifest anxiety and low manifest anxiety on college students' performance on a coding task. The conclusions of the study, based upon the hypotheses, were as follows: 1. Level of anxiety does not affect performance on a coding task. 2. The level of white and level of varied noise does not affect performance on a coding task. 3. Varied noise has a positive effect on performance on a coding task.
