Final answer:
The internal working model significantly influences the development of self-concept and a social self by shaping how individuals perceive themselves and their interrelations with others, thereby affecting their behavior and social interactions.
Step-by-step explanation:
The internal working model is a concept in psychology that refers to the mental representations a person has of themselves, their relationships with others, and the world around them. This model plays a critical role in the development of a child's self-concept, which is one's perception of oneself. A positive self-concept is crucial as it leads to greater confidence, independence, and willingness to engage in new activities. During the toddlerhood stage, as per Erikson's stages of psychosocial development, children begin to establish autonomy and build confidence in their abilities. As children grow, particularly in elementary school, they engage in social comparison, which can further refine their self-concept by comparing themselves with others.
In adolescence, Erikson posits that individuals reassess their self-concept and strive for identity formation. Drawing from these ideas, along with the influence of social experiences that affect our level of self-efficacy as described by Bandura, we understand that the internal working model is intimately tied to how individuals develop a sense of self within a social context and how they interpret and respond to varying social situations.
Therefore, the internal working model primarily influences the development of self-control, self-concept, and a social self, as it determines how individuals perceive themselves and their capabilities, which in turn shapes their behavior and interactions with others.
