Harre's positioning theory posits discourse as the concrete context within
which selves are produced, but accentuates the dissociation between the phy
sical engagement in a conversation and 'location' in a conceptual interpers
onal space. The thesis that positioning involves selective attention, and t
hat selected positions express ongoing transformations in the hearer's expe
riential realm is expanded here initially by reference to Gibson's direct-p
erception theory. The concepts of indexical and symbolic affordances are in
troduced to describe the function of utterances in setting parameters for h
earer's behavioural and social-relational engagement, respectively. This im
plicates a construct of 'psychological value' (i.e., the affective intensit
y and valence of elements of experience), as proposed by C. G. Jung. The es
say draws attention to the idea of symbol forming as a process whereby abst
ract self/world relations are articulated in one's actions and thoughts, an
d in which context the 'reception' of others' actions and utterances as hav
ing positioning implications may be understood.
