Janet designed an experiment on the relationship between age of first human contact and friendliness in cats. She was interested in whether having their first contact with humans at a younger age would predict later friendliness in cats. She randomly assigned kittens to one of three groups. The first group was first handled at birth, the second group was first handled at 6 weeks, and the third group was first handled at 12 weeks. Each group of kittens were a litter born from a different mother cat. All kittens were handled by the same experimenter, who handled them the exact same way every time. All kittens were measured on friendliness at the conclusion of the experiment (when they were 14 weeks old), to determine whether age at first handling affected friendliness. Which of the following is a threat to internal validity in Janet's study? A. age of first human contact B. the friendliness of the kittens at 14 weeks C. each group of kittens were a litter born from a different mother cat D. the same experimenter handled the kittens in the same way eventimo
