Dogs Don't Remember

Dogs Don't Remember: Episodic Memory May Distinguish Humans

Dogs are wonderful creatures. Our dogs recognize me and are always happy to see me. Dogs are also smart and successful creatures. Our dogs have learned several cute tricks. But dogs (and other non-human animals) are missing something we take for granted: episodic memory. Dogs don't remember what happened yesterday and don't plan for tomorrow.

In defining episodic memory, Endel Tulving argued that it is unique to humans. Experience influences all animals. Most mammals and birds can build complex sets of knowledge or semantic memory. You and I also remember the experience of learning these complex sets of information. Dogs don't.

Episodic remembering is mental time travel and depends on a few crucial cognitive capabilities. First, in order to experience episodic remembering, an individual must have a sense of self. Most non-human animals have a dramatically different experience of self than we do. For example, most animals (and young humans) fail to identify themselves in mirrors. If I look in a mirror and see that I have something stuck between my teeth, I try to correct the problem. (I also wonder why my friends didn't tell me I had something stuck between my teeth.) In contrast, put a red dot on a child's forehead, put the child in front of a mirror, and watch what happens. Young children are more likely to reach for the baby in the mirror than for their own foreheads. Dogs treat the dog in the mirror as another dog; not as themselves. Most animals fail at the red dot mirror task.

A self concept is not, however, enough to ensure episodic remembering. Mental time travel is the other critical cognitive capability. I understand that yesterday is different from today and that tomorrow will be different as well. We realize that when we remember, the mental experience is a disjointed slice of time. Thus episodic remembering is the combination of a self concept and mental time travel: recollecting the self in that other time period. Mental time travel also enables planning for the future. Dogs don't plan for particular future events although they have a general expectation of when dinner will appear.

Tulving also argued that since episodic memory in a recent evolutionary development, it is particularly likely to suffer damage and loss. Anterograde amnesia is the failure to encode and remember new episodic memories. Anterograde amnesiacs can learn from single experiences without recollecting the experience. They retain a clear sense of self, but they have difficulty with time as personally experienced. Because they lack episodic memory, they can't recall what occurred just before the present moment and constantly feel like they just woke up. If you meet an anterograde amnesiac, leave the room, and return after 10 minutes, you'll remember having met the individual, but the amnesiac won't remember having met you.

My dogs display this particular failure of episodic remembering. If I walk into the backyard, the dogs are overjoyed to see me and act like they haven't seen me for days. If I stay in the backyard, they quickly become bored with me. If I go inside and return after 10-15 minutes, my dogs are overjoyed to see me and act like they haven't seen me in days. They don't remember that I was in the backyard just a few minutes ago.

Arguing against Tulving's notion that episodic remembering is unique to humans is hard. Showing the impact of a single experience is not enough. Even without episodic memory, humans can show the impact of single events. Anterograde amnesiacs can learn fear, learn new skills, and gain new conceptual knowledge. Normal humans also gain knowledge without remembering when and where they learned the information (see my earlier post on Haven't I Seen You Somewhere Before).

Although I appreciate Tulving's conception of episodic memory, I've always been troubled by the difficulty of documenting that other animals have episodic memory. Episodic remembering hinges on the conscious experience of the self in some other time and place. Episodic memory is thus hard to demonstrate without the verbal ability to describe conscious experience.

Nonetheless, in a recent edited volume (The Missing Link in Cognition: Origins of Self Reflective Consciousness, edited by Terrance and Metcalf), several individuals have taken up the challenge. In my next post, I'll present the counter-argument: Dogs don't remember, but maybe chimps do. Since some non-human primates can perform self recognition with mirrors, they may perform episodic remembering. Even if they can't describe their memories, chimps may engage in mental time travel. My dogs, however, are stuck in an eternal present.

Yikes! It sounds like you have a heck of a beta hound. If we could mix mine and yours, we would likely have a wonderfully middle of the road hound!

What kind of Coon Hound did you adopt? I have an American English coon hound. Have you studied the history of the breed?

Dogs exist in an entirely separate and superior plane of moral, spiritual, and cosmic existential plane of conceptual continuity to humans.

Witness your own dog and the freak show in D.C. and on the tube.

This guy is just a writer in search of a topic. :)

He is half coon hound and half basset hound is all we know. He certainly is a beta but he growls all of the time. He would be great as a singleton in a household full of children as he doesn't get along with our other four dogs but loves people.

He is a sweet dog but not good in the car as he barfs before the car is even started.

Here is a pic of him.

True dat, and he obviously doesn’t have a dog.

He looks to have some Plott hound in him. You should check out these 2 sources:

www.coonhoundcompanions.com

http://coonhoundgazette.com/index.html

Check out the history and you might have a new sense of pride in your Coon Hound! My hound’s breed was first introduced by George Washington!

The current trend is tacks or nails hidden within meat and cheese placed in dog parks.

I can only think of one uniformly evil group of suspects.

That is disgusting! I’d wager only the disgusting vermin would do such disgusting actions!

The merciful part of me advises Googling for this stuff.

It’s pretty bad and spreading rapidly.

This just in: dogs are not people. Also, dogs can not tell time.

Otherwise, its amazing how accurately a dog knows, usually within minutes, it is meal time.

No matter, dogs are great!

Most animals fail at the red dot mirror task.

Maybe because not all of them can see color?
