Bandura and Mischel's Study on the Effects of Modelling on Delay

Bandura and Mischel's study on the effects of modelling on delay of gratification in children showed that

B) children who saw models delay gratification were less likely to delay gratification.
C) children's observations of models affected their behaviour only if the behaviour of the model matched the usual behaviour of the child in a similar situation.
D) impulsive children imitated models who delayed gratification but children with self-control did not imitate the models who chose immediate gratification.
