This is the full quote with the information about other terminology is:

In the sociology of scientific knowledge (SSK), for example, reflexivity has been used to refer to the application of the same approaches used to analyse the process of scientific knowledge production to SSK itself (Wynne 1993). In social research, it can refer to the researcher’s awareness of his or her own positioning in relation to the subject of research and how this affects both what is being researched and the researcher’s observations (which always entail interpretation, as nothing speaks for itself) (Anderson 2008). Generally speaking, reflexivity requires self-questioning, in particular a willingness and ability to question one’s own assumptions, how they relate to societal power structures, and how they shape one’s actions. More specifically, here, we use reflexivity to mean a theoretically informed capacity to critically analyse one’s underlying assumptions, expectations, and positioning in relation to one’s involvement in outreach. It is not simply an internal thought process, but rather a type of thinking tied to action. Reflexive thinking makes possible ways of acting that would not otherwise be possible.
