People interpret dogs' emotions based on context. When shown a picture of a dog adjacent to a leash, they interpret the dog as being happy; when the same picture is manipulated to show the dog adjacent to a vacuum cleaner, they interpret the dog as being unhappy.

Knowridge Science Report · Are we misreading our dogs? New research says yesMany dog owners believe they can easily understand their pets’ emotions. A wagging tail means happiness, a guilty look means regret, and a lowered head means sadness. But new research from Arizona State University suggests that humans often misread their dogs’ emotions. The study, published in Anthrozoös, found that people judge their dog’s emotions based […]

Do we all see red as the same colour? We finally have an answer

It is impossible for us to know exactly how another person's experience of the world compares to our own, but a new experiment is helping to reveal that colour is indeed a shared phenomenon

One of the trickiest things to make people understand about perception (at least the way I do it), is that colors are all in the mind.

I've thought of a new way to do it, sorta.

Let's imagine a wonderbeast.
It has eyes that detect every single wavelength of electromagnetic radiation, from some gamma ray nonsense to actual meter-long radio waves.
And it perceives these wavelengths as distinct grayscales.

Does it see any colors?
It sees the wavelength that we would call "yellow", and would be able to agree with us that it is "yellow" if it has been trained in English... but it's "yellow" is a grayscale in a set that is near-infinitely larger than our set of colors.

Hopefully this makes clear the idea that wavelengths are not colors. Wavelenghts are just wavelengths. We either detect them or we do not.
If we do detect them, and iff our brains "colorize" them to make them stand out, only then do we perceive color.

Because "color" refers not to any wavelengths, but to the visceral visual experience.
Something unique to the perception system, that certain sorts of nerve impulses (not light) get interpreted as completely non-real color experiences.

idk, does that work?
