Explanation:

Jean Piaget was a psychologist who developed a cognitive theory according to which, infants go through different stages since the moment they are born and until adolescence and with each stage their thinking gets more complex and logical.

The first of the stages according to Piaget is called the sensorimotor stage and it takes place since birth to approximately 2 years of age. During this time, the kids rely in their senses to gain understanding of the world around them.

There are some substages in this stage and one of them is the stage known as coordination of secondary circular reactions which takes place between 8 and 12 months of age. During this stage, the behavior of the infants is goal oriented trying to reach for objects or finding hidden objects.

In this example, Jenny is eleven-months-old and she uses the toy golf club to bring another toy within reach, we can see that she is oriented to trying to reach for objects and also she falls between the age range for the coordination of secondary circular reactions. Therefore, Jenny is in the coordination of secondary circular reactions of the sensorimotor stage.
