Very interesting, very curious what effect alcohol would have on my actions.

Alcohol myopia

According to a growing body of evidence collected over the last three or more decades, people’s Jekyll and Hyde behaviour while drinking can be understood by a simple idea which has some intriguing ramifications.
The alcohol myopia model says that drink makes our attentional system short-sighted and the more we drink, the more short-sighted it becomes. With more alcohol our brains become less and less able to process peripheral cues and more focused on what is right in front of us. It’s this balance between what is right in front of us and what we don’t notice around the edges that determines how alcohol affects us in different situations.
Here are a few effects which imbibers will recognise immediately:

• An ego boost: when people drink, they often feel better about themselves. This may be because the attentional short-sightedness induced by alcohol makes all our shortcomings float away and so we feel closer to our ideal selves. This is probably one of the reasons it is so potentially addictive, it is self-actualisation in bottle form.
• Real worries can get worse: if we’ve had a bad day and we sit quietly with a drink, alcohol can make it worse because all the peripheral cues which are potential distractors are cut out and all we see are our problems.
• Pleasure in the moment: the flip-side of this attentional focus is that if, while drinking, we are doing something enjoyable, we find it easier to ignore any nagging doubts or stray worries wandering through our minds. We can be totally in the moment listening to music, watching sports or talking with a good friend.
• In the zone: it’s even possible that for some types of task it may increase performance as we let go of our insecurities. Perhaps that’s why so many writers wrote with a glass of whisky at their side.

What this means for me would be drink coffee while coding and don’t drink it while thinking about design and while trying to study the requirement documents.

So:
Use caffeine for short-term performance on a focused task (such as an exam).
Avoid caffeine for tasks that require broad creativity and long-term learning.
(Disclaimer: The greater altertness, larger short-term memory capacity, and eased recall might make the memories you do make of higher quality.)

This is why I love the saying the plural of anecdotes is not data.

In other words,
1. In a popular area there’s more temptation to fiddle with the data or analysis until you get what you expect.
2. The more people who test an idea, the more likely someone is going to find data in support of it by chance.
The authors produce evidence of the two effects above in the context of papers written about protein interactions in yeast. They conclude that “The second effect is about 10 times larger than the first one.”

can you train yourself to see this change? I think I’m too slow or absent minded to notice this.

The researchers used an infrared eye-tracking device to measure the diameter of the participants’ left pupils up to 2,000 times per second while they performed the tasks. They found that pupil dilation was tightly coupled with the time at which the decisions were made, and betrayed the participants’ decisions before they were openly revealed. In the first experiment, maximum pupil dilation was observed during the 2-second interval in which the button was pressed. In the second, where there was a delay between the choice and the participants’ report of which number they had chosen, their pupils were maximally dilated during the interval at which they chose the digit. During task three, maximum dilation was again observed during the time at which the participants “chose” the underlined number.

Now I just need to wake up earlier than usual to get some sunlight and exercise!!! although my problem with waking up early has always been about having my creative times between late nights and early mornings.

The new research has applications for more than 3 million shift workers and Alzheimer’s patients who suffer from lack of a regular sleep pattern.
Studies have shown that this lack of synchronization between a shift worker’s rest and activity and light/dark patterns leads to a much higher risk of cardiovascular disease, diabetes, seasonal depression and cancer over decades.

The ability to speak a second language isn’t the only thing that distinguishes bilingual people from their monolingual counterparts—their brains work differently, too. Research has shown, for instance, that children who know two languages more easily solve problems that involve misleading cues. A new study published in Psychological Science reveals that knowledge of a second language—even one learned in adolescence—affects how people read in their native tongue. The findings suggest that after learning a second language, people never look at words the same way again.

Apple are evil?

by John on February 8, 2010
Mike Croucher wrote a post the other day explaining why he’s going to buy an iPad. He said that one of the objections to the iPad he’d heard was
Apple are evil because they take away control of how we use their devices.
I teased Mike that I would never say “Apple are evil.” On this side of the Atlantic we’d say “Apple is evil.” But in the UK it is accepted usage to say “Apple are evil.”
“Apple” is a collective noun when used to refer to Apple Inc. British English treats collective nouns as plural, but American English treats them as singular. Although the British usage sounds odd to my American ears, it makes sense just as much sense as the American convention. You could argue for plural verbs because corporations are made of individual people, or you could argue for singular verbs because the corporations act as a single entity. See Grammar Girl’s tip on collective nouns for more background.

Again with the numbers:
30
32
The first number is the likelihood, expressed as a percentage, that a child born to parents whose incomes fall within the top 10 percent of Americans will grow up to be at least as wealthy.
The second is the percentage likelihood that a person born into the bottom 10 percent of society will stay at the bottom.
Just to drive the point home, here’s a third number: 1.3
That’s the percentage likelihood that a bottom 10 percenter will ever make it to the top 10 percent. For 99 out of 100 people, rags never lead to riches.
