Final answer:
The correct terms that describe how a child's interaction with their environment can lead to maladaptive behaviors are 'transaction' and 'interdependent', and the attachment style where a child uses the parent as a base to explore is called 'secure attachment'.
Step-by-step explanation:
The two terms used to explain how a child's interaction with his/her environment can lead to the development of maladaptive behaviors are transaction and interdependent. These terms reflect the dynamic and complex exchange between the child and their environment, which can lead to either positive or negative behavior patterns. On the other hand, the attachment style where a child uses the parent as a base from which to explore their world is known as secure attachment. In this style, the child feels comfortable venturing out and then returning to the parent for comfort and safety, exemplifying a strong and healthy bond.
