Herzog comments on the transformation of intrapsychic representations
as it occurs through the vicissitudes of an interaction as well betwee
n infant and parent in a developmental course as between patient and p
sychoanalyst during psychoanalysis. The author illustrates by means of
a child analytic case study that this change of representation depend
s mainly on an open exchange between perception, memory, and represent
ations. If this dynamic fluency is forestalled - a state which Herzog
terms ''mimetic occlusion'' - an opening has to be regained in psychoa
nalytic treatment. In child analyses an access for a representational
reopening can be provided by playing. The author differentiates betwee
n a ''displacement play mode'' in which intrapsychic conflicts are ext
ernalized through the manipulation of symbolic objects, and ''interact
ive enactment'', a play mode in which conflictual issues are negotiate
d directly between patient and psychoanalyst. A mimetic reopening of t
he representational world following an aporia can be reached according
ly to the libidinous cathexes, the object relations, and the shape of
the inner relationship of the self to the self of the other - the obje
ct.
