Dr. Penrose is studying the reflexes that infants exhibit at or shortly after birth. He speculates about the ways in which these reflexes might be, or perhaps were at one time, important for infants' survival. Dr. Penrose's approach illustrates which one of the following theoretical perspectivesa. Biological
b. Behaviorist
c. Sociocultural
d. Developmental systems

a. Biological

Explanation:

In psychology, the Biological perspective is a perspective that takes into account the physical factors that can influence behavior or psychological development. In other ways, it explains physical and psychological development based on physical factors people are exposed to.

In this example, Dr. Penrose is studying the reflexes that infants exhibit at or shortly after birth (which is something physical) and she speculates how this reflexes were important for infants survival. Since she is taking a physical factor into consideration to explain infants' survival, this would be an example of a Biological perspective.
