Intrinsic vs. Extrinsic Rewards (and Their Differences from Motivations)

Hi,

the post is indeed very insightful. I would like to know are rewards like recognition like pat on back, praiseworthy words infront of peers be considered as instrinsic rewards as these are non tangible or will it be considered as extrinsic rewards as its external and not internal to one's satisfaction. Can we classify all non tangible rewards (acknowledgement of good work infront of peers, pat on the back etc) as intrinsic rewards?

thanks
