these programs, that there would be supervisors involved that have 

 that specific kind of expertise. 



Senator Kerry, Did I hear you correctly in suggesting, or maybe 

 not suggesting but stating overtly that this one dolphin's aberrant 

 behavior that has been publicized — I should not say aberrant, prob- 

 ably natural behavior tnat has been reinforced. But are you sug- 

 gesting that it was taught or reinforced somehow to engage in 

 that? 



Dr. Stone. I am suggesting that by not directing those animals' 

 behavior toward appropriate interactions, that kind of behavior be- 

 comes self-reinforcing. Using modem techniques of behavioral con- 

 ditioning and positive reinforcement, there is no reason why those 

 dolphins would not prefer a more appropriate type of interaction. 



Senator Kerry. OK. Well, let me wrap this up regrettably. I 

 think there are a number of interesting areas that I did want to 

 pursue a little more, but we are going to have to leave the record 

 open. We will leave it open just for a few days, long enough so that 

 staff can get some of these additional questions to you. 



And I would ask your cooperation in getting tne answers back 

 and writing as fast as you can so that we can complete the record 

 here, which I really want to do. And, you know, what I really want 

 to do is build both sides of the arguments here as strongly as pos- 

 sible so that we have explored this as thoroughly as we can, and 

 then we will kind of work with the administration and see where 

 we come up on the reauthorization. 



I think it has been very interesting and I think you have all ac- 

 quitted yourselves very very well. It has been very educational and 

 I appreciate enormously the time and for some of you the distance 

 traveled to be here. It has been very instructive. Thank you. We 

 stand adjourned. 



[Whereupon, at 4:25 p.m., the hearing adjourned.]
