Psychology homework

Discuss the importance of these qualitative approaches of inquiry in building and sustaining a "critical psychology" that is interested in understanding how:
1) knowledge is produced, used and appropriated (depending on the different functions of knowledge and its contexts, including psychology) from a constructivist view that questions the fallacy of objectivity (or the "world as given")

2) experience is framed and signified (depending on the social, cultural and particular context of the group or individual), which critically questions the fallacy of the centrality of the individual.
3) the underlying ideologies, discourses and relations of power oppress, stigmatize or alienate certain sections of society, which assumes the importance of studying the uses of language and knowledge (which are not neutral or "objective").
