To find out the superiority of human heuristic search to set up new web search model based on cognition,an integrate strategy combined visual perception and goal recursion is proposed.A method of(fMRI functional magnetic resonance imaging) meeting ACT-R(adaptive control of thought-rational) is used.An fMRI experiment on simplified 4€? Sudoku paradigm is preformed to get the activation pattern of brain regions associated to the mental processing.Based on tasks analysis,an integrate strategy combined visual perception strategy and goal recursion strategy is assumed and a production system is presented.Based on the procedural system,an ACT-R cognitive system is programmed to simulate the integrated strategy used.Compared ACT-R prediction with fMRI result,difference on response time is 0.3 seconds and the average correlation on BOLD(blood oxygen level-dependent) response is about 0.95.It is indicated that integrated strategies is one of superiority of human heuristic search,which help to select efficient information,shorten the scale of processing,weaken the memory burden and speed up search.
