Sydney residents are resorting to increasingly sophisticated measures to prevent sulphur-crested cockatoos from opening and raiding household wheelie bins, detailed in new research published in the journal Current Biology.
But despite the nuts' value -- or perhaps because of it -- parrots are also willing to share their treats and the tokens to buy them with other birds. Given the option, the birds will transfer the precious metal rings to a friend in a neighboring cage so they, too, can enjoy some nutty nosh -- even without the promise of reciprocation, Brucks' latest research shows.

It is generally accepted that vertebrate animals experience pain; however, there is currently inconclusive evidence that the affective component of pain occurs in any invertebrate. Here, we show that octopuses, the most neurologically complex invertebrates, exhibit cognitive and spontaneous behaviors indicative of affective pain experience. In conditioned place preference assays, octopuses avoided contexts in which pain was experienced, preferred a location in which they experienced relief from pain, and showed no conditioned preference in the absence of pain. Injection site grooming occurred in all animals receiving acetic acid injections, but this was abolished by local anesthesia. Thus, octopuses are likely to experience the affective component of pain.

"What is striking," the investigators write, "is that simply being alone with their own thoughts for 15 minutes was apparently so aversive that it drove many participants to self-administer an electric shock that they had earlier said they would pay to avoid."

What’s going on is that without some kind of direct experience to use as a touchstone, people don’t have the context that gives them a place in their minds to put the things you are telling them. The things you say often don’t stick, and the few things that do stick are often distorted. Also, most people aren’t very good at visualizing hypotheticals, at imagining what something they haven’t experienced might be like, or even what something they have experienced might be like if it were somewhat different.
Time is seen in a particularly different light by Eastern and Western cultures, and even within these groupings assumes quite dissimilar aspects from country to country.

But here is the real challenge: How can we learn to recognize our own ignorance and misbeliefs? To begin with, imagine that you are part of a small group that needs to make a decision about some matter of importance. Behavioral scientists often recommend that small groups appoint someone to serve as a devil’s advocate—a person whose job is to question and criticize the group’s logic. While this approach can prolong group discussions, irritate the group, and be uncomfortable, the decisions that groups ultimately reach are usually more accurate and more solidly grounded than they otherwise would be.
For individuals, the trick is to be your own devil’s advocate: to think through how your favored conclusions might be misguided; to ask yourself how you might be wrong, or how things might turn out differently from what you expect. It helps to try practicing what the psychologist Charles Lord calls “considering the opposite.” To do this, I often imagine myself in a future in which I have turned out to be wrong in a decision, and then consider what the likeliest path was that led to my failure. And lastly: Seek advice. Other people may have their own misbeliefs, but a discussion can often be sufficient to rid a serious person of his or her most egregious misconceptions.

This is not to say that skill doesn’t matter — merely that in a competition in which all the leaders are highly skilled, randomness may explain the difference between triumph and failure. Good luck plus skill beats bad luck plus skill any time.

The reason why purple and violet look similar to us is because they stimulate our cones in a similar way, but most other animals don’t share the same types of cones and “post-processing”. This means that to other animals, purple and violet may look completely different!
Now imagine a violet flower petal with a purple pattern on it. Depending on the particular shades, this pattern might be completely invisible to us, while many other animals could see it as clearly as we can see an orange pattern on green background.

It’s especially important that kids get bored — and be allowed to stay bored — when they’re young. That it not be considered “a problem” to be avoided or eradicated by the higher-ups, but instead something kids grapple with on their own.
We’ve stopped training children to do this. Rather than teach them to absorb material that is slower, duller and decidedly two-dimensional, like a lot of worthwhile information is, schools cave in to what they say children expect: fun. Teachers spend more time concocting ways to “engage” students through visuals and “interactive learning” (read: screens, games) tailored to their Candy Crushed attention spans. Kids won’t listen to long lectures, goes the argument, so it’s on us to serve up learning in easier-to-swallow portions.
