Precedence Effect Parameter Set

This is an example of a parameter set for task types 5 or 6 (precedence effect). The parameter which is varied randomly is spkbdel, and each value of it is weighted according to the weights provided with spkbwts.

Note that all text to the right of a semicolon is a comment, and is ignored by the COM program.
