Fixed vs Variable Ratio

[Jeffrey Nagelbush]

Almost every intro text I have examined, if it deals with the issure at all, 
says that VR schedules generally produces a higher rate of responding than 
FR schedules.  The one exception is the Myers text which clearly states, in 
the caption to a figure, that "A predictable (fixed) schedule produces a 
higher response rate than an unpredictable (variable) schedule."  He clearly 
is including both interval and ratio schedules.

My question:  Are all the other texts I checked correct or is Myers the only 
one to have it right?
