Dear All, I have performed a factorial (3 x 3 x 3) experiment in the following manner: 1st factor: task rules (two well-learned, one brand new) 2nd factor: three environments (two well-learned, one brand new) 3rd factor: response start time I have already performed a simple one-sample t-test analysis, which gives me good results, but I am wondering if the use of a 'full or flexible factorial' analysis (second-level) would be more appropriate. Would anybody suggest the steps I should follow for this analysis? Thanks in advance to you all All the best, Alan Fermin Neural Computation Unit Okinawa Institute of Science and Technology Okinawa, Japan
