Repeated-measure ANOVAs.
Context and Order enter as between-subject factors.
Feedback and Period (1-4) enter as within-subject factors.
The temporal order of observations is ignored.

************************************************************
Data format for MTN-ARL42-wn-Ss.dat and TXT-ARL42-wn-Ss.dat
is described in CRFeedback2/prog/html/CRFB2_empir_ARL_profile.html

ASCII file with one row per subject and the following columns:
    * 1. Sbj -- Subject number (451-492, 999)
    * 2. Group -- 1=FastLow1, 2=FastLow2, 3=SlowHigh1, 4=SlowHigh2
    * 3. Task -- 1=MOTION throughout  or   2=TEXTURE throughout
    * 4. Context -- 1=Slow, 2=Fast
    * 5. Order -- 1=Feedback_first, 2=No_feedback_first
    * 6. W -- ARL2 value for the "warm-up" initial block
    * 7-10. F1-F4 -- ARL42 values during the four feedback blocks
    * 11-14. N1-N4 -- ARL42 values during the four no-feedback blocks

Note that this data format throws away the temporal order of observations. They are rearranged depending on Order so that in the resulting ASCII file all feedback ARLs are listed in columns F1-F4 and all no-feedback ARLs are listed in columns N1-N4.
