Subclaims¶

q2 i? Providing subgoals was not beneficial on the Missionaries and Cannibals problem due to limited alternative moves and problem space. → Ahmad Tarmizi 1991 q2 i? On an extended 5-Missionaries and 5-Cannibals variant, providing subgoals facilitated subjects' performance. → Ahmad Tarmizi 1991 (2)

The thesis reports, citing Reed and Abramson's experiments on the Missionaries and Cannibals problem with two subgoal variations, that "providing subgoals was not beneficial" on the shorter problem. No effect size is printed.

"Results indicated that providing subgoals was not beneficial due to a lack of alternative moves at most states and the limited problem space."
