Results for Cech Mental Comparison Lab - Fall 2007


        CONGRUITY EFFECT
 results based on 13 people (I excluded 1 person for very high error 
 rates, and I also counted long RTs (over 3817 msec:  4 standard
  deviations above the group mean) as errors)

(1= smallest animal; 4= largest, so 12 = comparison of 1 & 2; 
   23 = comparison of 2 & 3, and 34 = comparison of 3 & 4)

      1          2         3
LA: 1161.5     1192.4      848.9
SM:  986.0     1173.1      903.6


        DISTANCE EFFECT
 results based on 13 people as above

(1 = comparisons of adjacent animals (12, 23, 34); 
 2 = comparisons of animals separated by 1 intervening animal (13, 24); 
 and 3 = most separated animals (14)

      1          2         3
    1034.3      978.5     873.3

error rate:  0.099 (actually, on the high side for this type of experiment!)
