As a part of my lab experiment, participants had to answer questions for BIS and BAS (BAS reward, drive and fun) scales. The correlation matrix shows that BIS is significantly positively correlated with BAS reward, BAS fun and BAS drive. Has anyone experienced similar issues? Is this an issue? If yes, is it possible (and how) to correct for that?BIS (Behavioral Inhibition System) and BAS (Behavioral Activation System) - I administered the scale developed by Carver and White (1994), as presented on pg. 323 in their work Behavioral inhibition, behavioral activation, and affective responses to impending reward and punishment: The BIS/BAS scales (Journal of Personality and Social Psychology, 67, 319-333). I would assume that BIS should not be positively correlated with any of the BAS scales as BIS is related to avoidance motivation and BAS is related to approach motivation.I.e. a person scoring high on BIS should not be scoring high on BAS measures and vice versa. The variables are intended as predictors. I want to examine if BAS (approach motivation) sensitivity predicts a rightward bias in product choice, and if BIS (avoidance motivation) sensitivity predicts a leftward bias.
