Jb. Asendorpf et al., SELF-AWARENESS AND OTHER-AWARENESS .2. MIRROR SELF-RECOGNITION, SOCIAL CONTINGENCY AWARENESS, AND SYNCHRONIC IMITATION, Developmental psychology, 32(2), 1996, pp. 313-321
Eighteen-month-old children were tested for mirror self-recognition us
ing the classic rouge test or an alternative procedure, for social con
tingency awareness by being closely imitated for a long time, and for
the capacity for communication by synchronic imitation. The classic mi
rror rouge test was shown to produce false negatives. Most recognizers
and nonrecognizers became aware of being imitated and imitated the ac
tivity of a model, but only recognizers engaged in sustained synchroni
c imitation of the model. The results support our hypothesis that self
-recognition and spontaneous perspective-taking develop in close synch
rony because both require a capacity for secondary representation.
