Abstract
The dual-process theory of human cognition proposes the existence of two systems for decision-making: a slower, deliberative, problem-solving system and a quicker, reactive, pattern-recognition system. We alter the balance of these systems in a number of computational simulations using three types of agent equipped with a novel, hybrid, human-like cognitive architecture. These agents are situated in the stochastic, multi-agent Tileworld domain, whose complexity can be precisely controlled and widely varied. We explore how agent performance is affected by different balances of problem-solving and pattern-recognition, and conduct a sensitivity analysis upon key pattern-recognition system variables. Results indicate that pattern-recognition improves agent performance by as much as 36.5 % and, if a balance is struck with particular pattern-recognition components to promote pattern-recognition use, performance can be further improved by up to 3.6 %. This research is of interest for studies of expert behaviour in particular, and AI in general.

- 5.
A square in Tileworld can only contain one item (see Sect. 2), one item-on-square pattern encodes one item and the agent doesn’t encode its own location.

Due to an error in the simulation code used in a previous version of this paper [27], the results reported in this section consistently differ from those reported in the corresponding section of [27] by a factor of 10. The results reported in this section use a rectified version of the simulation code and are correct.
- 7.
All F and p values for the effects discussed are equal to those outlined for average frequency of pattern-recognition system use.
