Immediately thereafter, Lucienne’s mother asked, "where is Papa?" In response, Lucienne turned and pointed toward Piaget’s office window where she was used to seeing him. In this event, Lucienne’s behavior could be viewed as a naturalistic example of ___.

Secondary circular reaction: In psychology, the term "secondary circular reaction" is described as one of the different sub-stages of the very first stage of cognitive development theory i.e., sensorimotor stage and it was proposed by Jean Piaget. The given sub-stage starts from the age of four months and lasts through eight months of age.

At this stage, the child tends to repeat pleasurable activities that generally involves actions and objects as well by engaging one's own body. In this period, a child shows clear intended actions and often combine different schemas to achieve specific goals.

In the question above, Lucienne’s behavior could be viewed as a naturalistic example of secondary circular reaction.
