The LICAI Model

The LInked model of Comprehension-based Action planning and Instruction taking

[li kai]


LICAI is a model that simulates performing tasks by exploration where the tasks are given to the user in the form of written exercises that contain no information about the correct action sequences (Kitajima and Polson, 1997). LICAI's comprehension processes and the action planning processes (Kitajima and Polson, 1995) are based on Kintsch's (1988) construction-integration theory for text comprehension. The model comprehends the instructions and generates goals which are then stored in episodic memory (Kintsch and Welsch, 1991). The action planning process is controlled by goals retrieved from memory cued by displays generated by the application.

The model assumes that the instruction comprehension is a strategic process; instruction texts must be elaborated using specialized strategies that guide generation of goals. Representations of goals that lead to correct actions are restricted by the construction-integration architecture. The model predicts that successful exploration requires perfect matching of goal representation and the label on the correct object.

Extension to LICAI

A new model, CoLiDeS, simulating users Web navigation, has been developed as an extension of LICAI. Visit CoLiDeS model demo page for more information. (November 23, 2001)
