Final answer:
Janet Spector's work was distinctive for its holistic approach, integrating cultural contexts and indigenous perspectives in her archaeological interpretation.
Step-by-step explanation:
Janet Spector's archaeological work was unusual due to her incorporation of different perspectives into the interpretation of past cultures, particularly those of Native Americans. Her approach shifted from a purely scientific examination of artifacts to include the societal and cultural contexts that accompanied them, which was pioneering at the time. Moreover, she sought to understand the past not just through the lens of the archaeologist but by integrating the voices and views of the people connected to the artifacts she studied.
