Abstract: David Herman regards scripts, sequences and stories as narrative microdesigns of storyworlds construction, and explores the ways scripts cue the sequences recipients to process the sequences as stories in ways of activating the world knowledge stored in their mind, which is a study on script-story interface. Based on and going beyond structuralist and cognitive-scientific perspectives on sequences, Herman’s study on sequences not only examines the interrelations between scripts and narrativity, but also discusses the effects of scripts on literary interpretation diachronically and synchronically. Undoubtedly, Herman’s study on sequences lays the foundation for the establishment of postclassical narratology to a certain degree, and is a successful attempt to set up the research paradigm of cognitive narratology by himself.
