Which of the following represents the correct sequence of stages in prenatal development, beginning with the earliest?

A. Proximal versus distal influences: This contrasts immediate (proximal) versus more distant (distal) causes; while relevant, Bella’s cross-cultural comparison targets a different theoretical question.
B. Nature versus nurture: This debate concerns biological versus environmental origins of behavior; comparing cultures could inform it, but Bella’s focus on cultural differences in grandmother roles is more about context-specific vs universal patterns.
C. Universal versus context-specific factors: comparing North American and African cultural groups tests whether grandmother roles are universal (same across cultures) or context-specific (vary by culture).
D. Quantitative versus qualitative factors: This contrasts types of differences (amount vs kind); Bella’s question is about cultural patterning, not measurement style.
E. Continuity versus discontinuity: This concerns whether development is gradual or stage-like; Bella’s cross-cultural role analysis isn’t directly addressing that issue.

A. Kent (conditions for conformity): Studying conformity focuses on social influence processes (social psychology), not the multi-layered environmental systems emphasized by ecological systems theory.
B. Ella (observations in homes, schools, neighborhoods): Bronfenbrenner’s ecological systems theory emphasizes multiple environmental contexts (microsystem, mesosystem, exosystem, macrosystem), so observing homes, schools, and neighborhoods fits that framework.
C. Sidney (questionnaires measuring cognitive, social, emotional development): Measuring developmental domains is core to developmental psychology but doesn’t specifically indicate an ecological-systems focus on nested environmental contexts.
D. Jeanne (tracking IQ over ten years): That’s a longitudinal interest in stability/change of intelligence; it’s not specifically an ecological-systems approach unless she’s also examining environmental layers.
E. Clint (visual stimuli and looking time): This describes infant perception/attention research (preferential looking), not ecological systems theory.
