Subjective experience of episodic memory and metacognition: a neurodevelopmental approach.

[22q11.2 deletion syndrome]

Episodic retrieval is characterized by the subjective experience of remembering . This experience enables the co -ordination of memory retrieval processes and can be acted on metacognitively . In successful retrieval , the feeling of remembering may be accompanied by recall of important contextual information . On the other hand , when people fail (or struggle ) to retrieve information , other feelings , thoughts , and information may come to mind . In this review , we examine the subjective and metacognitive basis of episodic memory function from a neurodevelopmental perspective , looking at recollection paradigms (such as source memory , and the report of recollective experience ) and metacognitive paradigms such as the feeling of knowing ). We start by considering healthy development , and provide a brief review of the development of episodic memory , with a particular focus on the ability of children to report first -person experiences of remembering . We then consider neurodevelopmental disorders (NDDs ) such as amnesia acquired in infancy , autism , Williams syndrome , Down syndrome , or 22 q 11 .2 deletion syndrome . This review shows that different episodic processes develop at different rates , and that across a broad set of different NDDs there are various types of episodic memory impairment , each with possibly a different character . This literature is in agreement with the idea that episodic memory is a multifaceted process .
