The trials had been conducted off 0700 so you’re able to 1100, regarding fifteen Will get in order to fifteen July for all age. Early in the day studies show that amount of time spent within this 0.twenty-five meters is highly predictive of the quantity of periods [3, 11]; so we have fun with that level in these analyses. Samples had been 10 min a lot of time and you will included 69 focal lady (2008
