Decoding dogs: optimists or pessimists?

Can science help decode the emotional life of dogs? A series of articles highlight the process of research, from experiment to science writing to public reaction.

Animal psychology challenges our best research methods. Just because the original article is critiqued, doesn’t mean it’s not valuable. We need more feasable experiments, even if they are far from perfect. They are all steps in getting from anecdote to what can be considered facts and scientific consensus.

The original science article:

quote:
“Here we use a new ‘cognitive bias’ measure of animal affect to show that dogs which exhibit high levels of SRB [ undesirable separation-related behaviour ] in a separation test also appear to have a more negative underlying mood.”

When a Dog’s Dish Seems Half Empty

By SINDYA N. BHANOO, October 11, 2010

quote:
“What the scientists say is that dogs that exhibit anxiety when left home alone by their owners may have bigger problems — they may be in a permanent bad mood.”

Insightful NYT commenters already hint at problems with the scientific conclusions, tongue in cheek posts hinting at both liking the article while not entirely trusting its conclusions:

Maybe the dogs who always looked for the food bowl were in the grips of a compulsive eating disorder!— Liz

Wondering… if the owner’s perception on life impacts on their pet’s perception…

An in-depth critique:
A scientist blogger takes time to dissect the original methods. Link was posted next to the NYT article, I like that.

Pessimistic Pooches? Depressed Doggies? Not So Fast!

by Jason G. Goldman, October 13, 2010

quote:
“Does Fido see the cup as half full? Is your dog pessimistic? Last time we saw headlines like these they were about a certain barnyard animal. Remember “Pampered pigs ‘feel optimistic'”? I didn’t like it then, and I don’t like it now.”

Goldman’s post goes to the core of methodology. Really interesting, it’s not really about the dogs but about how we go about refining our knowledge of our best friends.

I looked up the pig posts link, as a reference to myself for future musings:
