Special conditions of set 11. The visual discrimination was 

 made less difficult by putting a cover over 15 by 40 cm, of the 

 nest box and by cutting out the openings over the electric boxes 

 until they were 36 by 13 cm. instead of 23.5 by 13 cm. The 

 strengths of stimuli were the same as in set 1, but only two 

 kittens were used for each strength.
