CHREST (Chunk Hierarchy and REtrieval STructures) is a cognitive architecture that models human perception, learning, memory, and problem solving. It is distinctive in its emphasis on the importance of perception and attention, and in following human constraints such as limitations on short-term memory and processing speed. EPAM (Elementary Perceiver and Memoriser) and MOSAIC (Model of Syntax Acquisition in Children) are closely related to CHREST.

CHREST has been shown to accurately model many different aspects of human cognition across different domains. It is currently the only cognitive architecture being developed in the United Kingdom.
