According to bandura, what four cognitive processes are necessary for imitation of behavior that has been only observed?

The 4 necessary cognitive processes are:
1. Attention: This is the way in which by means of observation we grasp what happens around us.
2. Retention: This is learning and passing on to the long-term memory what we have just observed.
3. Reproduction: It happens when the observed, retained and learned previously is repeated.
4. Motivation: Motivation is the desire to reproduce what we observe and learn.
