Answer:
practice is confounded with the time of day
Explanation:
Gross motor coordination is also known as Gross motor skills, and can be described as those things that are involved in movement and coordination of the arms, legs, and other large body parts and movements.
They involve the large muscles of the body that enable such functions or activities as walking, kicking, sitting upright, lifting, and throwing a ball.
In this case, the experiment or research that the researcher is carrying out on the gross motor coordination at some specific times of the day, indicates that practice is confounded with the time of the day.
This is an example of Substage 3: Secondary circular reactions. This substage includes organizing sensation and new plans. For instance, a kid may suck his or her thumb unintentionally and after that later purposefully rehash the activity. These activities are rehashed in light of the fact that the newborn child discovers them pleasurable.
