1 00:00:02,040 --> 00:00:07,080 Speaker 1: Welcome to brain Stuff. From How Stuff Works, Hey, brain Stuff, 2 00:00:07,120 --> 00:00:11,400 Speaker 1: Lauren vogelbam here, Researchers from Johns Hopkins University have confirmed 3 00:00:11,440 --> 00:00:14,760 Speaker 1: what most dog owners already know. The dogs have strong 4 00:00:14,800 --> 00:00:17,400 Speaker 1: emotional bonds with their owners and want to help when 5 00:00:17,400 --> 00:00:20,720 Speaker 1: we're upset. In a paper titled in homage to Lassie 6 00:00:20,880 --> 00:00:24,200 Speaker 1: Timmy's in the Well, Empathy and pro Social Helping in Dogs, 7 00:00:24,320 --> 00:00:27,480 Speaker 1: published in eighteen issue of the journal Learning and Behavior, 8 00:00:27,920 --> 00:00:31,320 Speaker 1: researchers described how dogs pushed through a door when they 9 00:00:31,360 --> 00:00:36,000 Speaker 1: heard their owners crying. Lead author Emily Sandford, a graduate 10 00:00:36,000 --> 00:00:39,000 Speaker 1: student in psychological and brain sciences, set in the paper 11 00:00:39,520 --> 00:00:42,479 Speaker 1: we found dogs not only sense what their owners are feeling. 12 00:00:42,760 --> 00:00:44,560 Speaker 1: If a dog knows a way to help them, they'll 13 00:00:44,600 --> 00:00:49,120 Speaker 1: go through barriers to provide that help to them. Study 14 00:00:49,159 --> 00:00:51,920 Speaker 1: found dogs may be hardwired to comfort us when we're sad, 15 00:00:52,120 --> 00:00:54,680 Speaker 1: regardless of whether the dog knows us or not. When 16 00:00:54,680 --> 00:00:58,000 Speaker 1: a stranger and the dog's owner cried, the dogs approached 17 00:00:58,000 --> 00:01:01,160 Speaker 1: whoever was bawling in a submissive way. The dogs, the 18 00:01:01,160 --> 00:01:05,280 Speaker 1: researchers concluded, responded empathetically to the person's emotions and not 19 00:01:05,400 --> 00:01:08,520 Speaker 1: their own needs. But Sandford's research is the first to 20 00:01:08,560 --> 00:01:12,039 Speaker 1: show that our beloved four legged friends are specifically moved 21 00:01:12,040 --> 00:01:14,959 Speaker 1: to action when they see their owners in emotional distress. 22 00:01:15,560 --> 00:01:18,880 Speaker 1: The experiment involved thirty four pet dogs of varying breeds. 23 00:01:19,160 --> 00:01:22,440 Speaker 1: Some were big, some small. Here's how it all played out. 24 00:01:22,880 --> 00:01:25,800 Speaker 1: Researchers told the dogs owners wanted a time to stand 25 00:01:25,840 --> 00:01:29,640 Speaker 1: behind a clear door held shut by magnets. The owners 26 00:01:29,680 --> 00:01:33,240 Speaker 1: dogs could see and hear what was going on. Researchers 27 00:01:33,240 --> 00:01:36,240 Speaker 1: then had the humans hum Twinkle Twinkle, Little Star or 28 00:01:36,600 --> 00:01:39,960 Speaker 1: pretend to cry. While not all the dogs opened the door, 29 00:01:40,280 --> 00:01:43,280 Speaker 1: those that did opened it three times faster when they 30 00:01:43,280 --> 00:01:47,760 Speaker 1: heard their owners crying instead of humming. Researchers also measured 31 00:01:47,840 --> 00:01:51,000 Speaker 1: the dog's stress level. Those that were able to bolt 32 00:01:51,040 --> 00:01:54,240 Speaker 1: through the door to rescue their owners showed less stress, 33 00:01:54,440 --> 00:01:57,120 Speaker 1: even though they were upset by the crying. Even though 34 00:01:57,160 --> 00:01:59,840 Speaker 1: they were upset, they weren't too frazzled to take action. 35 00:02:00,040 --> 00:02:03,360 Speaker 1: Researchers concluded the dogs that didn't push the door open 36 00:02:03,480 --> 00:02:07,559 Speaker 1: were more stressed out. It seems the researchers surmised those 37 00:02:07,600 --> 00:02:10,240 Speaker 1: dogs were so troubled by their owners crying that they 38 00:02:10,280 --> 00:02:14,200 Speaker 1: couldn't do anything to help. Sandford said dogs have been 39 00:02:14,200 --> 00:02:16,720 Speaker 1: by the side of humans for tens of thousands of years, 40 00:02:16,800 --> 00:02:19,680 Speaker 1: and they've learned to read our social cues. Dog owners 41 00:02:19,680 --> 00:02:22,720 Speaker 1: can tell that their dogs sense their feelings. Our findings 42 00:02:22,720 --> 00:02:26,119 Speaker 1: reinforced that idea and show that, like Lassie, dogs who 43 00:02:26,120 --> 00:02:28,640 Speaker 1: know their people are in trouble might spring into action. 44 00:02:33,919 --> 00:02:36,720 Speaker 1: Today's episode was written by John Paritano and produced by 45 00:02:36,760 --> 00:02:39,120 Speaker 1: Tyler Clang.
