Pretty low form to discuss the speakers rather than what is being said... Peace.

I read the original paper, and, I must say, I am very impressed with the quality of the study for an undergrad! I think, regarding people with only 30 jumps taking part, what is interesting to note, is that regardless of the (arguably) low level of experience of some of the participants, the self reported anxiety of the "experienced" group was significantly lower than the "novice", yet their measured cortisol levels weren't. The argument about the sample size and jump numbers would be a lot more valid if the psychological difference was low as well. It is not mentioned in the paper, but I assume, the person doing the data analysis would have checked whether they get any significance if they remove the low jump people from the sample, and, I suspect, the result was much the same, hence they included everyone. I don't know if this is true though...
