Point: A strength of the social learning approach is that key principles are supported by evidence.
For example, Smith and Lloyd (1978) dressed babies aged 4-6 months alternately in boys' and girls' clothes, irrespective of their actual sex.
When dressed as boys, they were given hammer-shaped rattles and encouraged to be active, while when dressed as girls, they were handed cuddly dolls and reinforced for being passive
Link: Therefore, this suggests that gender-appropriate behaviour is ingrained at an early age through differential reinforcement, supporting social learning theory.
