I agree with you. I remember skimming the paper and finding it interesting but wondered if selecting that term might set too many imaginations running. I don't have a problem with their calling it imagination, though.

But consider that many would object if I stated jumping spiders have an active imagination. Yet, this is not far fetched if you accept that imagination includes planning against a learned model.

Insects are known to be capable of learning. They need to be able to remember routes or learn which locations to prefer or avoid. Jumping spiders are known for their ability to carry out and hold complex plans in their head. Though a form of imagination, most would hesitate to call it that.
