Abstract: Cognitive Load Theory (CLT) and Dual Space Theory (DST) offer differing accounts of learning in complex settings. CLT argues that reducing processing demands on working memory (i.e. reducing cognitive load) will facilitate learning. Conversely, DST suggests that learning is improved by encouraging learners to focus on task rules (rule space search) rather than task instances (instance space search). Despite these differences, CLT researchers have proposed that the theories are complementary, suggesting that rule space search is contingent on low cognitive load. Three studies were conducted to examine this proposal with particular focus on the goal free effect. Study 1 trained participants on a complex task under conditions of high or low rule space search with cognitive load held constant. Results indicated that the high rule space search group acquired greater knowledge despite equivalent cognitive load between the groups. However, results may have been confounded by motivational differences. Study 2 manipulated rule space search and cognitive load in a 2 (goal type) x 2 (information level) between-subjects design. Manipulations were intended to create conditions where cognitive load and rule space search were both high or low, contrary to their proposed dependence. Results however were mixed. Whilst cognitive load and rule space search were unrelated in between-group comparisons, they were negatively related overall, consistent with CLT’s proposal. Study 3 refined the previous 2 x 2 design to clarify these findings. Results indicated that groups encouraged to search rule space did so independently of cognitive load, though results were not entirely consistent with either theory. Taken together, results tentatively suggest that cognitive load does not influence rule space search in all situations. The theories may therefore be independent explanations of learning in complex settings.
