It is unknown which regions of the brain are most or least active for golfers during a peak performance state (Flow State or "The Zone") on the putting green. To address this issue, electroencephalographic (EEG) recordings were taken on 10 elite golfers while they performed a putting drill consisting of hitting nine putts spaced uniformly around a hole each five feet away. Data was collected at three time periods, before, during and after the putt. Galvanic Skin Response (GSR) measurements were also recorded on each subject. Three of the subjects performed a visualization of the same putting drill and their brain waves and GSR were recorded and then compared with their actual performance of the drill. EEG data in the Theta (4 \u2014 7 Hz) bandwidth and Alpha (7 \u2014 13 Hz) bandwidth in 11 different locations across the head were analyzed. Relative power spectrum was used to quantify the data. From the results, it was found that there is a higher magnitude of power in both the theta and alpha bandwidths for a missed putt in comparison to a made putt (p<0.05). It was also found that there is a higher average power in the right hemisphere for made putts. There was not a higher power in the occipital region of the brain nor was there a lower power level in the frontal cortical region during made putts. The hypothesis that there would be a difference between the means of the power level in performance compared to visualization techniques was also supported.

Warehouse workers are critical to the success of any business and supply chain. It is important to understand different factors that can influence an employee's performance and satisfaction at work. In order to determine some best practices, 173 students at Arizona State University participated in an online warehousing simulation in a controlled laboratory setting. Participants were subject to different combinations of time pressure and put-away errors (i.e. when items that need to be picked by a warehouse worker are not located where they are supposed to be). A preliminary analysis shows that the largest impact is that of time pressure on worker productivity. As time pressure increases, the time required to complete a task decreases. The trade-offs of using time pressure as a management option are discussed.
