An Information Search Model Integrating Visual, Semantic and Memory Processes

This study aims at presenting a computational model of visual search including a visual, a semantic and a memory process in order to simulate human behavior during information seeking. We implemented the memory process, which is the most important part of the model based on the Variable Memory Model (Arani, Karwan, & G., 1984; Horowitz, 2006). To compare model and humans, we designed two experiments where participants were asked to find the word among forty distributed on the display, which best answers a question. The results showed good fits on different features extracted between empirical and simulated scanpaths.
