social learning allows us to mimic what we have observed from others by retrieving it from our memories.

Explanation:

Through social learning we observe and model other people's behaviour and we can later be able to retrieve that information and mimic it every step by step.

We learn through observation, imitation and modelling what we have obtained through social learning.

Polly had observed her mom baking and this information was preserved in her memory that she is able to use it later and follow it as she saw it.
