Factors affecting conscious awareness in the recollective experience of adults with Asperger’s syndrome

Bowler, Gardiner, and Grice (2000a) have shown a small but significant impairment of autonoetic awareness or remembering involved in the episodic memory experiences of adults with Asperger’s syndrome. This was compensated by an increase in experiences of noetic awareness or knowing. The question remains as to whether the residual autonoetic awareness in Asperger individuals is qualitatively the same as that of typical comparison participants. Three experiments are presented in which manipulations that have shown differential effects on different kinds of conscious awareness in memory in typical populations are employed with a sample of adults with Asperger’s syndrome. The results suggest that the experiences of remembering reported by such individuals, although reduced in quantity, are qualitatively similar to those seen in the typical population. The results are discussed in the context of current theories of awareness in episodic memory.
