The research group also assessed the two lines of dogs on tests used by Scott and Fuller (1965). dogs showed less exploratory behavior in an empty room, had more subjects that froze in response to a loud horn, and a greater percentage of individuals avoided humans (Murphree, Dykman, & Peters, 1967a). These differences appeared at months of age and persisted through to the last test at 18 months of age. Some differences remained stable, and some became amplified with increasing age. The Arkansas researchers also investigated the behavior of crosses between the two lines. They conducted reciprocal crosses and tested the crossbred puppies for the and on the behavioral tests taken from Scott and Fuller (1965). Between offspring of reciprocal crosse, there was no apparent difference. Both crosses behaved nearly identically to the dogs when assessed for as well as on the behavioral tests. McBryde and Murphree (1974) undertook an investigation of whether it was possible to change an pointer into a normal onequestion with both theoretical and practical importance. They noted that the pointers still retained the normal behavior of the scent of quail. Using this kernel of normal behavior, the reinforcer of “pointing”to access to a quail wing, and sometimes a normal dog for social facilitation of responses, the authors trained five nervous pointers to hunt succesfully, including retrieval which necessarily involve approaching a human. This behavioral improvement did not, however, generalize to the standard behavioral tests administered to the dogs.
