Final answer:
Clarence's behavior indicates a preoccupied internal model of attachment, which is akin to the insecure ambivalent-resistant attachment style in children, where individuals are clingy yet doubt the security of their attachment, leading to anxiety and fear of abandonment.
Step-by-step explanation:
In his relationship with his wife, Clarence experiences jealousy, anxiety about whether she returns his feelings, and a general sense of insecurity about himself. This pattern of behavior is characteristic of individuals with a preoccupied internal model of attachment.
Preoccupied attachment in adults corresponds to the resistant or insecure ambivalent-resistant attachment style observed in children. In this style, individuals may exhibit clingy behavior while also struggling to trust or feel reassured by their attachment figure. This pattern can lead to higher levels of anxiety concerning the attachment and fears of abandonment.
The child who uses the parent as a base from which to explore the world is demonstrating a secure attachment style. In this style, the child feels safe to explore their environment, and they seek comfort from their caregiver upon experiencing distress or when reunited after separation.
