IQ test
Wednesday, September 30th, 2009 | Uncategorized | Comments Off
Test that tries to find innate intellectual ability, and not learned ability.
It is now widely thought that a child’s results in an i q test can be affected by his or her environment, cultural and ethnic background, and teaching.
There is widespread questions over the accuracy of iq tests, however they are still commonly used as a diagnostic tool when children display learning problems.
The French psychologist Alfred Binet (1857–1911) devised the first intelligence test in 1905.
The IQ (from the German Intelligenz-Quotient), was coined by the German psychologist William Stern in 1912 as a proposed method of scoring early modern children’s intelligence tests.
It is calculated according to the formula: IQ = MA/CA x 100 in which MA is ‘mental age’ (the age at which an average child is able to perform given tasks) and CA is ‘chronological age’, hence an average person has an IQ of 100 ± 10.
Although the term “IQ” is still in common use, the scoring of modern IQ tests such as the Wechsler Adult Intelligence Scale is now based on a projection of the subject’s measured rank on the Gaussian bell curve with a center value (average IQ) of 100, and a standard deviation of 15, although different tests may have different standard deviations.
Intelligence tests were first used on a large scale in the USA in 1917 during World War I for two million drafted men, and their subsequent widespread use for education and employment decisions has provoked protests from minority groups who contend the tests are culturally biased and discriminatory.
IQ scores have been shown to be associated with such factors as morbidity and death rate, parental social status, and to a considerable degree, parental IQ. While its inheritance has been investigated for almost a century, controversy remains as to how much is inheritable, and the mechanisms of inheritance are still a subject to some debate.
IQ scores are used in many contexts: as predictors of educational achievement or special needs, by social scientists who study the statistical distribution of IQ scores in populations and the relationships between IQ score and other variables, and as predictors of job performance and income.
The average IQ scores for many populations have been rising at an average rate of three points per decade since the early 20th century with most of the gain in the lower half of the IQ range: a phenomenon called the Flynn effect. It is disputed whether these changes in scores reflect real changes in intellectual abilities, or merely problems with past or present testing methods.
We All Have Heard of Weight Watchers

A Closer Look
Well, they say that it is not a diet. However, they do believe that it is a way of life. Sounds interesting enough! You basically get to eat what you like while putting your main focus on the nutrition intake. Basically, you choose foods that you like and Weight Watchers also provides you with a wide variety of recipes that you can choose from. Some of the plans include whole grains and low fat foods with fruits and vegetables. There are two main plans that you can choose from and stick to. You have the choice of the Flex Plan where you basically eat anything while keeping track of the point values. Then there is the Core Plan where you can eat as much nutritional food as you want to because they help to keep you fuller for a longer period of time.
More than Just Food
You would probably think that, just like with any other diet, all you basically have are the instructions laid out for you. Maybe a couple of books that you probably would never read and the choice of foods and supplements that you will need all conveniently written on a list. Well, think again because, with the Weight Watchers Diet, you get more than all of that. There are actual meetings that you can attend, even online. There is a newsletter as well as several recipes. Have you ever noticed that there is also a line of Weight Watchers foods in your grocers freezer? Well, that is another great thing about this ‘diet’. They offer frozen foods but they are not required to be eaten for this diet.
Is this the Right Diet for Me?
Consider this: being able to prepare foods that your family can even eat. There is no more special dinner preparations for you. That is one thing that you can consider. Are you willing to continue the diet as a way of life and not just some short term fad diet? Are you willing to count calorie intake and keep up with balancing your nutritional intake as well as calories and fat? As with most diets, exercise is important; so, are you willing to add exercise to your diet as well? Consider the meetings and undivided support that you will have. There is no doubt that a combination of 45 years of expertise and leaders will be there to walk you through anything that you need help with. The leaders have been successful with the diet, so they aren’t just a so called expert, they actually have hands on experience and a success story to share with you.
Maybe it isn’t the Right Diet?
Well, that is definitely something that you will want to talk to your doctor about first. Perhaps it is overwhelming because of all it entails and you don’t know whether you can handle it. Keeping up with all of the calories, weight, fat intake or counting everything; who has the time for all of that? You don’t think that you could continue this for any length of time? These are questions that you will definitely want to ask yourself. Your answers will help you decide.
So What Can I Eat?
There are so many recipes to choose from that there is bound to be something that you will like. Not to mention the wide variety of Weight Watchers frozen food. You have a choice to pretty much eat what you want but keep up with counting calories and fat that you consume. Then, of course, there is another plan in which you choose to eat nutritional foods and eat as much as you like to eat because they are nutritional. There is even a plan for men. This is a program designed specifically for men because their structure is different than a woman’s. They tell you the proper exercising to follow, etc.
There are many things that you should take into consideration when you are initiating a diet. First of all, be sure that you are fully aware of all that is entailed in the diet. Make sure that you understand what is expected of you as well. Then, of course, you are going to want to talk with your doctor about it. This may not be the right one for you and he will help you make that decision. Know their philosophy and the ins and outs of the diet. Speak to others who have tried it. Keep in mind that like with any diet, it is wise to exercise while on it. This may just be the right diet for you considering the great support system that they have. When considering this diet, the pro’s may have out done the con’s.
