The Seattle Longitudinal Study of Adult Intelligence has followed a group of more than 5000 people for well over four decades. The program began in 1956 and participants have been tested across a whole gamut of mental and physical abilities at seven year intervals since that date.
The study has found:
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.
As I said in my discussion of different scripts, the Hellenic languages use the Greek alphabet. Here it is. I’m afraid the table is a little complicated, because (a) each letter has a name, which it’s useful to know, and (b) there are some differences in pronunciation between Ancient Greek (which is still a language that people want to learn today), and Modern Greek.
Children’s understanding, and their use of memory and learning strategies, is a considerably more complex situation than most of us realize. To get some feeling for this complexity, let’s start by looking at a specific area of knowledge: mathematics.
Here’s a math problem:
Pete has 3 apples. Ann also has some apples. Pete and Ann have 9 apples altogether. How many apples does Ann have?
This seems pretty straightforward, right? How about this one:
It does appear that most component processes of cognition decline with advanced age if the difficulty level is sufficiently high. For example, the following processes have all shown age effects:
Reading is a deceptive skill, for it is not a single process, but a number of processes. Thus, while you might be a fluent reader, in that you can swiftly and easily decode the letter-markings, and quickly access the meaning of the words, that doesn't mean you're a skilled reader of informational texts.
Here are some notes on the water cycle:
Precipitation & flow: “whether they are typhoons or Scotch mists, mountain torrents or field ditches or city sewers, they are simply water sinking back to base level, the sea.”
Evaporation = the act of passively presenting water to the atmosphere to be soaked up + vaporized by the sun’s energy.
Transpiration= evaporation thru plants
I don't think anyone's going to try arguing that fruit and vegetables are not good for your health! We know they're good. But that's just general "oh, I know it's good for me" — do you know that the benefits are not only for your general health, your protection against obesity and diabetes, cancer and heart disease, but also for your brain. Actually, there's two aspects to this. An unhealthy diet (one rich in junk food, in saturated fat and sugar) is actively bad for your brain, and (the right) healthy diet is actively good for your brain.
Let me start by saying that if you're healthy and are eating a good balanced diet, there should be no need for you to take supplements. I also want to emphasize that the best way of meeting your body's needs for certain vitamins and minerals is to get them from food. In some cases, for one reason or another, this may not be possible. For example, as a (mostly) vegan, I take iron and B12 supplements, to make up for these deficiencies in my diet. Elderly adults with small appetites may also find it hard to get all the nutrients they need from their diet.
In a 1987 experiment (1), readers were presented with a text that included one or other of these sentences:
or
Both texts went on to say:
