The question of interpreting the concept codes with respect to level of abstractionwas investigated by having three experienced laddering interviewers (minimum of500 ladders) assign level designations to the 25 revised concept codes. The resultsare presented in the third column of Figure 3, with the differences between conceptcodes assigned boxed. Note the relatively high correspondence between coders(#1 vs #2 with 23 matches; #1 vs #3 with 22 matches; and #2 vs #3 with 22matches), which suggests a high degree of commonality of meanings can beachieved when the appropriate level-specific phraseology in developing concept codenames is utilized
