"your perspective is too limited. not everything is immediately observable. in addition, people can think about what is happening, both internally and in the world at large." these words might be spoken by to albert bandura; julian rotter

This is most likely said by Rotter to Bandura. Although both theorists talk about Social Learning theory, Albert Bandura's theory only dwells on how personality is shaped by observation on the environment. Rotter furthermore expanded Bandura's theory by claiming that shaping human personality lies between the direct experiences of the individual and of the environment.  He contended that personality is an interaction between the both stimuli, and does not depend on only either of the two.
