Is that your only concept of abstract thought? It's pretty narrow.Do they also talk about meanings?
A common yardstick for abstract thought is called "theory of mind":
"...non-human animals have the ability to attribute mental states (such as intention, desires, pretending, knowledge) to themselves and others, including recognition that others have mental states that are different from their own..."
An example, which scientists believe indicate the ability for abstract thought:
"Western scrub jays both cache food and pilfer other scrub jays' caches. They use a range of tactics to minimise the possibility that their own caches will be pilfered. One of these tactics is to remember which individual scrub jay watched them during particular caching events and adjust their re-caching behaviour accordingly. One study with particularly interesting results found that only scrub jays which had themselves pilfered would re-cache when they had been observed making the initial cache. This has been interpreted as the re-caching bird projecting its own experiences of pilfering intent onto those of another potential pilferer, and taking appropriate action."
