Behavior of all foxes included in the study is tested by the standardized scheme. Videos 1 and 3 demonstrate behavior of foxes from aggressive and tame populations in the standard test.

The standard test includes five steps:
1- observer approaching fox cage;
2- observer stays near closed cage;
3- observer is near open cage but does not initiate tactile contact;
4- tactile contact;
5- observer stays near closed cage.

Each step (except step one) is 1 minute long (in the movie the length of each step was decreased about two times). Fox behavior during the entire test is videotaped to preserve a permanent record, and to allow subsequent detailed analyses of fox behavior during the test. Each fox is tested at least twice at several age points by the same observer.
