Final answer:
John Bowlby's attachment theory posits that an individual's internal working model of attachment consists of expectations about the nature of interpersonal relationships, specifically whether they will be rewarding. This framework affects an individual's approach to relationships throughout life. Thus, the correct answer to the student's question is a) expectations about whether interpersonal relationships will be rewarding.
Step-by-step explanation:
British psychologist John Bowlby developed the concept of attachment theory, which explores the strong emotional bonds formed between infants and their primary caregivers, typically the mother. According to Bowlby, an individual's internal working model of attachment is a cognitive framework comprising expectations about the nature of interpersonal relationships. This internal working model includes a) expectations about whether interpersonal relationships will be rewarding, which guides individuals in how they relate to others throughout their lives. It is within this framework that one anticipates and interprets others' responses and behaviors in various social contexts.
Bowlby's concept of a secure base is foundational to the idea of healthy attachment, where the caregiver provides a stable and safe environment for the child. The aspects of one's internal working model include how responsive caregivers are to needs, the nature of mutually enjoyable interactions, and the continuation of influence through adult relationships, including romantic partnerships and even attachments to deities or inanimate objects in some belief systems.
The options provided in the question are specific aspects of self-perception and beliefs about the external world, which while relevant to a person's overall social and psychological functioning, are not directly part of Bowlby’s internal working model of attachment. Therefore, the correct answer to the student's question would be a) expectations about whether interpersonal relationships will be rewarding.
