I suppose, very quickly, it depends on what is defined as social learning, plus how one defines locus of control-and how one manages that in themselves and others.
Rewarding behaviour...such as the gold star approach was banned in most schools in my earlier teaching career...because when the child did not get one- it was suggested that said far more than the award of one.....but again...depends if the child cares or not....locus of control....I dont get many usefuls here...am not quite sure how to play that game-yet 
) but it doesn't bother me-because I have a strong LoC (can read up about this in any GCSE psychology course sylabus- oh and I got a badge here for being particularly helpful -and I still dont know why! Crumbs
Anyway.....I want to look at the measures on that paper...I notice they worked with the range....ok.
And finally, (bit news at ten-ish I know) thought this link might be related in some way:

Now, you did ask for views on this...meaning no right or wrong answers...and no personal attacks....oh dear, come to think of it: this might reflect that my contributions have officially deteriorated over time ;0)
