Cognitive Polyphasia, Themata and Blood Donation: Between or Within Representation
Abstract
Cognitive polyphasia has typically been understood through the notion of situated
knowledge. This paper adds to this body of work by suggesting that the processes
involved in representation, namely themata, be considered in concert with the content of
the representation. We present research that investigated why so few people in Australia
donate blood when most people agree that blood donation is a worthwhile, altruistic act.
Using word association data we show that the representational field associated with
blood donation has contradictory normative and functional meanings that are not
delineated by donor status. We suggest that the thema of self/other gives rise to a
heterogeneous field that manifests as polyphasic responses bound to the salience of the
social context.
