Answer:
Reflexivity.
Step-by-step explanation:
The technique of reflexivity is applied when the researcher has the aim to discover, as he/she is researching, the best approach for his/her study. As the example given in the exercise, Barbara was trying to determine which was her role within that community, which shaped her study as well. Reflexivity is just that; the aim of a researcher to find the best approach when studying a particular subject, allowing it as well to influence him/her.
