A study conducted by researchers at Pennsylvania State University investigated whether time perception, an indication of a person's ability to concentrate, is impaired during nicotine withdrawal. After a 24-hour smoking abstinence, 23 smokers were asked to estimate how much time had passed during a 30-second period. The average amount of perceived time that elapsed was 35.758 seconds with a standard deviation of 10.787 seconds.

A study conducted by researchers at Pennsylvania State University investigated whether time perception, an indication of a person's ability to concentrate, is impaired during nicotine withdrawal. After a 24-hour smoking abstinence, 23 smokers were asked to estimate how much time had passed during a 30-second period. The average amount of perceived time that elapsed was 35.758 seconds with a standard deviation of 10.787 seconds. Is there evidence at the 0.05 level that nicotine withdrawal has a negative impact on time perception - that is, the mean perceived time elapsed is greater than the actual time period of 30 seconds?
