ANAGRAM PROBLEMS WERE ATTEMPTED AFTER 5 PRESENTATIONS OF A 10-WORD LIST; 3 DIFFERENT LISTS WERE USED. COMPARED TO A CONTROL CONDITION WITH NO LIST, POSITIVE TRANSFER WAS PRODUCED BY PRIOR EXPOSURE OF THE SOLUTIONS, OR OF WORDS ASSOCIATIVELY RELATED TO THE SOLUTIONS, WITH GREATER FACILITATION PRODUCED BY EXPOSURE OF THE SOLUTIONS. WHEN WORDS UNRELATED TO THE SOLUTIONS WERE PRESENTED, BUT INSTRUCTIONS STATED THAT ASSOCIATIONS EXISTED, NEGATIVE TRANSFER OCCURRED. THE FINDINGS ARE INTERPRETED IN TERMS OF DIFFERENCES IN THE AVAILABILITY OF SOLUTIONS AND ARE RELATED TO STUDIES OF CATEGORY SETS IN PROBLEM SOLVING.
