Learning Outcomes

Upon completion of this assessment, students will be able to:

1. Analyze the interplay between biological predispositions and environmental influences on human development
2. Evaluate empirical evidence from feral child case studies in relation to major developmental theories
3. Synthesize research findings on critical periods, language acquisition, and attachment formation
4. Construct evidence-based arguments addressing contemporary debates in developmental psychology

Background Context

The nature-nurture debate represents one of the most enduring controversies in developmental psychology. While genetic factors establish the biological parameters of development, environmental experiences shape the expression of these potentials. Feral children—individuals raised in extreme social isolation with minimal or no human contact—provide unique natural experiments that illuminate the boundaries of human plasticity and the necessity of early socialization.

Cases such as Genie Wiley (discovered in California, 1970) and Oxana Malaya (discovered in Ukraine, 1991) demonstrate the devastating consequences of deprivation during critical developmental windows. These cases also raise profound questions about the existence of sensitive periods for language acquisition, the formation of attachment bonds, and the development of Theory of Mind. Your task is to examine how these extraordinary cases inform our understanding of normal developmental processes.

Task Description

Compose a critical analysis essay examining the influence of feral children on the nature-nurture debate. Your essay must address the following components:

Part A: Theoretical Framework (30%)

Provide a comprehensive overview of the nature-nurture debate, tracing its historical evolution from Galton’s initial formulation through to contemporary interactionist perspectives. Discuss how nativist (nature) and empiricist (nurture) positions conceptualize human development differently.

Part B: Case Study Analysis (40%)

Select two documented cases of feral children (e.g., Genie Wiley, Oxana Malaya, Victor of Aveyron, or the Indian wolf girls Kamala and Amala). For each case:

• Describe the circumstances of isolation and discovery
• Analyze the developmental outcomes observed post-rescue
• Evaluate what these outcomes suggest about critical periods in language, cognition, and social-emotional development
• Discuss the ethical considerations surrounding research with vulnerable populations

Part C: Synthesis and Implications (30%)

Synthesize your analysis to address the following questions:

1. Do feral child cases support a strong version of the critical period hypothesis, or do they suggest greater neural plasticity than previously assumed?
2. How do these cases inform contemporary child protection policies and early intervention strategies?
3. What limitations exist in drawing general conclusions from such extreme and rare cases?

Assessment Requirements

1. Academic Sources: Minimum of 6 peer-reviewed journal articles published between 2018–2026. Course textbooks may supplement but do not count toward this minimum.
2. Case Documentation: At least one primary source (original case study, documentary footage transcript, or first-hand research account) for each feral child discussed.
3. Theoretical Integration: Explicit engagement with at least two of the following: Bowlby’s Attachment Theory, Chomsky’s Language Acquisition Device, Lenneberg’s Critical Period Hypothesis, Bronfenbrenner’s Bioecological Model, or Vygotsky’s Sociocultural Theory.
4. Formatting: APA 7th Edition including title page, running head, page numbers, double-spacing, and hanging indent reference list.
5. Originality: Submit via Turnitin; similarity index must not exceed 15% excluding references.
