The benefits extend far beyond a higher IQ. In order to solve problems we hold information in our working memory, a greater amount of information means you'll improve your chances of solving the problem. You'll stand the most hope of improving your IQ if you manage to improve your working memory. Jaeggi and Martin Buschkuehl is now indicating that with specific and targeted training of working memory we may be able to improve our fluid intelligence. Like many aspects of cognition we're being forced to rethink this model. No matter the amount of learning or training you undertook your fluid intelligence remained constant for the duration of your life.

This part of your intelligence was always believed It describes your ability to solve abstract problems which do not depend upon skills and knowledge you've learned in the past. One aspect IQ tests measure is what's known as fluid intelligence.

Until recently most research has indicated that our IQ remains relatively fixed throughout our lives. Half of the population have an IQ score between 85 and 115. Only 2% of the population have an IQ greater than 128. How far you fall either side of this number determines roughly how unusual your IQ is.

Normalizing means the average IQ score is 100. It's best to think of your score as a number which represents your IQ compared to others, not as a measure of intelligence. Normalized scoring can be difficult to understand for those without a background in statistics. Once you've provided your answers we compare your results to people of your age and then we provide a normalized score. Like all IQ tests it does not attempt to measure the amount of information you have learned but rather your capacity to learn. The IQ test consists of a number of tasks measuring various measures of intelligence including short-term memory, analytical thinking, mathematical ability and spatial recognition.
