00:00:01,920 --> 00:00:06,440
Speaker 1: Welcome to brain Stuff production of I Heart Radio. Hey

2
00:00:06,519 --> 00:00:09,560
Speaker 1: brain Stuff, Lauren Vogelbaum. Here. If you're like me, you

3
00:00:09,680 --> 00:00:13,800
Speaker 1: love dogs, possibly more than people. Some days, their warm

4
00:00:13,880 --> 00:00:16,720
Speaker 1: eyes and doggie grins have me wrapped around their fluffy

5
00:00:16,760 --> 00:00:20,360
Speaker 1: pupper tails, and according to new research from the University

6
00:00:20,360 --> 00:00:24,720
Speaker 1: of Portsmouth's Dog Cognition Center, dogs deliberately make more facial

7
00:00:24,720 --> 00:00:27,720
Speaker 1: expressions when we're watching them, and it could be their

8
00:00:27,760 --> 00:00:30,480
Speaker 1: way to communicate with us. The study was led by

9
00:00:30,560 --> 00:00:34,000
Speaker 1: Dr Julienne Kaminsky and published in a seventeen issue of

10
00:00:34,040 --> 00:00:37,800
Speaker 1: Scientific Reports. Kaminski and her research team came to their

11
00:00:37,800 --> 00:00:41,680
Speaker 1: conclusion after watching twenty four different dogs, all family pets

12
00:00:41,680 --> 00:00:45,280
Speaker 1: of varying breeds and ages. Each dog was filmed individually

13
00:00:45,360 --> 00:00:47,519
Speaker 1: in a room with a person who went through various

14
00:00:47,520 --> 00:00:51,000
Speaker 1: scenarios including looking at the dog, looking away from the dog,

15
00:00:51,080 --> 00:00:54,840
Speaker 1: and giving the dog food. The scientists then studied the

16
00:00:54,840 --> 00:00:58,440
Speaker 1: dog's facial expressions using the Dog Facial Action Coding System

17
00:00:58,720 --> 00:01:01,960
Speaker 1: or Dog FACTS, which is a scientific tool for coding

18
00:01:02,080 --> 00:01:05,800
Speaker 1: canines facial movements. It was adapted from the FACTS system

19
00:01:05,880 --> 00:01:09,880
Speaker 1: created for humans back in night. Kaminsky and her team

20
00:01:09,920 --> 00:01:13,080
Speaker 1: discovered that each dog made animated faces when the person

21
00:01:13,120 --> 00:01:15,600
Speaker 1: in the room was looking at it, including raising its

22
00:01:15,600 --> 00:01:18,400
Speaker 1: eyebrows and sticking out its tongue a much more than

23
00:01:18,440 --> 00:01:21,360
Speaker 1: when the person's back was turned. In a press statement,

24
00:01:21,480 --> 00:01:24,920
Speaker 1: Dr Kaminsky said the findings appear to support evidence that

25
00:01:24,959 --> 00:01:28,240
Speaker 1: dogs are sensitive to humans attention and that expressions are

26
00:01:28,280 --> 00:01:33,759
Speaker 1: potentially active attempts to communicate, not simple emotional displays. Most

27
00:01:33,840 --> 00:01:37,520
Speaker 1: surprisingly is that even the presence of food didn't influence

28
00:01:37,560 --> 00:01:40,880
Speaker 1: the dogs as much as human affection. Kaminski said, we

29
00:01:41,040 --> 00:01:44,160
Speaker 1: knew domestic dogs paid attention to how attentive a human is.

30
00:01:44,480 --> 00:01:47,080
Speaker 1: In a previous study, we found, for example, the dogs

31
00:01:47,080 --> 00:01:49,720
Speaker 1: stole food more often when the human's eyes were closed

32
00:01:49,800 --> 00:01:52,520
Speaker 1: or when they had their back turned. In another study,

33
00:01:52,760 --> 00:01:54,920
Speaker 1: we found dogs follow the gaze of a human if

34
00:01:54,920 --> 00:01:58,080
Speaker 1: the human first establishes eye contact with the dog, so

35
00:01:58,160 --> 00:02:01,880
Speaker 1: the dog knows that the gaze shift is erected at them.

36
00:02:02,000 --> 00:02:04,880
Speaker 1: Kabinski says it's possible that the expressions of dogs have

37
00:02:05,080 --> 00:02:08,840
Speaker 1: changed as they've become more domesticated, but the study does

38
00:02:08,880 --> 00:02:11,800
Speaker 1: have its limits. Twenty four canines makes for a small

39
00:02:11,840 --> 00:02:14,760
Speaker 1: study sample, so it's likely that more dogs should be

40
00:02:14,800 --> 00:02:18,160
Speaker 1: studied to confirm these findings, which sounds like an excellent

41
00:02:18,200 --> 00:02:26,000
Speaker 1: research session to me. Today's episode was written by Sarah
