Psychological models developed elsewhere often mischaracterise African childhoods because they separate the child from the relationships, work and moral worlds that organise growth. Drawing on the developmental niche, sociocultural and resilience traditions, it proposes three carrying mechanisms: distributed co-regulation through sibling and kin care, guided participation in domestic, economic and school tasks, and collective meaning-making after adversity. The article then specifies what would count as credible evidence for each mechanism and how standard instruments would require cultural adaptation and qualitative anchoring before any quantitative comparison. The proposed mixed-methods architecture sequences ethnographic description, narrative inquiry and adapted measurement within longitudinal case comparison, with explicit attention to language, informant structure and ethical care. The contribution is a bounded, testable account of how African relational ecologies shape psychological growth and how that shaping can be studied without distortion.
