Subliminal learning achieved notoriety back in 1957, when James Vicary claimed moviegoers could be induced to buy popcorn and Coca-Cola through the use of messages that flashed on the screen too quickly to be seen. The claim was later shown to be false, but though the idea that people can be brainwashed by the use of such techniques has been disproven (there was quite a bit of hysteria about the notion at the time), that doesn’t mean the idea of subliminal learning is crazy.

People are poor at assessing their own memory
One thing research seems to show rather consistently is that, for older adults in particular, beliefs about one's own memory performance have little to do with one's actual memory performance¹. People who believe they have a poor memory are usually no worse at remembering than those who believe they have a good memory.
Humans are the animals that manipulate their cognitive environment.
This post is the second part in a four-part series on how education delivery is changing, and the set of literacies required in today’s world. Part 1 looked at the changing world of textbooks. This post looks at the oral equivalent of textbooks: direct instruction or lecturing.
Let's look a little deeper into the value of mnemonics for knowledge acquisition. By “knowledge acquisition”, I mean the sort of information you learn from textbooks — information that is not personal, that you need for the long-term.
In this context, I believe the chief value of mnemonic strategies is to help you recall information that needs to be remembered in a particular order. Thus we use mnemonics to help us remember the order of the planets, the order of musical notes on the stave, the order of the colors in a rainbow.
We forget someone’s name, and our response might be: “Oh I’ve always been terrible at remembering names!” Or: “I’m getting old; I really can’t remember things anymore.” Or: nothing — we shrug it off without thought. What our response might be depends on our age and our personality, but that response has nothing to do with the reason we forgot.
I have previously reported on how gait and balance problems have been associated with white matter lesions, and walking speed and grip strength have been associated with dementia and stroke risk.
Difficulty in remembering people’s names is one of the most common memory tasks that people wish to be better at. And the reason for this is not that their memory is poor, but because it is so embarrassing when their memory lets them down.
This isn’t just an issue at a personal level. It’s a particular issue for anyone who has to deal with a lot of people, many of whom they will see at infrequent intervals. Nothing makes a person — a client, a customer, a student — feel more valued than being remembered.
Speed-reading techniques
Like many memory improvement courses, speed-reading programs tend to make inflated claims. Also like memory programs, most speed-reading programs proffer the same advice. In essence, speed-reading techniques involve the following components:
Are you right-brained or left-brained?
One of the dumber questions around.
I think it’s safe to say that if you only had one hemisphere of your brain, you wouldn’t be functioning.
Of course, that’s not the point. But the real point is little more sensible. The whole idea of right brain vs left brain did come out of scientific research, but as is so often the case, the myth that developed is light years away from the considerably duller scientific truths that spawned it.
