Dr. Sue Johnson opens by presenting attachment science research revealing the genuine biological and neurological basis underlying romantic love and connection, extending established attachment theory research beyond its original primarily parent-child research context.

Why this biological grounding matters for understanding romantic love:

• This research provides scientific grounding for understanding romantic attachment bonds as reflecting genuine biological and neurological processes, not merely subjective emotional experience or cultural construction alone
• Johnson's extension of established attachment theory into adult romantic relationships specifically provides important scientific foundation for her broader Emotionally Focused Therapy approach
• This opening establishes the book's foundational scientific grounding, motivating its subsequent detailed practical relationship guidance
