This task looked at whether you prefer to empathise or systemise.

What does your result suggest?

Empathisers are better at accurately judging other people's emotions and responding appropriately. If you scored 15 and above, you are very empathic and would be an ideal person to comfort people in a time of crisis. Women in general are better at empathising.

What does your result suggest?

Systemisers prefer to investigate how systems work. A system can be a road map, flat pack furniture, or a mathematical equation – anything that follows a set of rules. A score of 15 and above suggests you're good at analysing or building systems. Men in general are better at systemising.

Scientists are keen to learn more about people who score high or low on both tests. They want to find out whether or not empathising and systemising are linked. Is a possible to make yourself more empathic?

Some scientists claim that our empathy and systemising abilities can be traced all the way back to prehistoric times. Find out more.

This task tested your ability to judge people's emotions.

What does your result suggest?

If you scored 0 - 3: Do you think you're good at judging how another person is feeling? Your score suggests this doesn't come to you quite so naturally.

If you scored 4 - 6: Your result suggests you have a balanced female-male brain and find it neither easy nor difficult to judge people's emotions.

If you scored 7 - 10: Your result suggests you are a good empathiser, sensitive to other people's emotions. Women generally fall into this category.

Professor Baron-Cohen at the University of Cambridge says that people usually perform better than they expect to on this test.

We asked you to measure your ring and index fingers. Your ratios came to:

It's thought that your ratio is governed by the amount of testosterone you were exposed to in your mother's womb. The ratio of the length of your index finger to the length of your ring finger is set for life by as early as three months after conception. Even during puberty, when we experience intensive hormonal changes, the ratio stays the same.

Men generally have a ring finger that is longer than their index finger, which gives them a lower ratio than women, whose ring and index fingers are usually of equal length.

This task looked at how you rate the attractiveness of a series of faces. The images you looked at were digitally altered to create slight differences in masculinity.

Your choices suggest you prefer more masculine faces.

Highly masculinised male faces possess more extreme testosterone markers such as a long, broad and lower jaw, as well as more pronounced brow ridges and cheekbones.

Interestingly, women's preferences are said to vary across the menstrual phase. A more masculine face is preferred during the 9 days prior to ovulation, when conception is most likely.

A typical 'attractive' female face possesses features such as a shorter, narrower, lower jaw, fuller lips and larger eyes than an average face.

This task tested your ability to mentally rotate 3D shapes.

Your score: 9 out of 12
Average score for men: 8.2 out of 12
Average score for women: 7.1 out of 12

What does your result suggest?

If you scored 0 - 6: Do you find yourself having to physically rotate a map to point in the direction in which you're travelling? This might explain why you scored in the lower range in the 3D shapes test. Twice as many women as men score in this category. Previous studies suggest that those with a female-type brain or with an arts background fall into this range.

If you scored 7 - 9: In past studies, 50 per cent of the people who scored in this range were women and 50 per cent were men.

If you scored 10 - 12: Are you an engineer or do you have a science background? People with these skills tend to score in this range. Past studies have concluded that people in this range have a more male brain.

Nearly a third of men who took this test got full marks, whereas less than 10 per cent of women managed the same. Find out why.

This task looked at your verbal fluency.

Your score: you associated 6 word(s) with grey and you named 3 word(s) that mean happy. We are assuming that all the words you entered are correct.

What does your result suggest?

If you produced 1 - 5 words: You are more of the strong, silent type with a male brain. You probably find it easier to express yourself in non-verbal ways, preferring action rather than words.

If you produced 6 - 10 words: Most people in this range have a female-type brain.

Women are said to use both sides of the brain when doing verbal tasks while men mainly use their left side. Studies have shown that girls develop vocabulary faster than boys. This difference in brain power is caused by levels of pre-natal testosterone. Find out more .

This task asked you how you would divide money.

If you had to split £50 with someone, you said you would demand £25

So far on the Sex ID test, men have demanded 51.6% (£25.80) of the pot and women have demanded 51.0% (£25.50), on average.

What does your response suggest?

Sex differences are small in this task. Demanding less than 60% of the pot (ie £30) is more typically female. Demanding more than 65% of the pot (ie £32.50) is more typically male.

Scientists believe that people with lower testosterone levels tend to take fewer risks so they are probably more willing to keep less for themselves. Those with higher testosterone levels tend to drive a harder bargain and are less compromising.

Men's testosterone levels fluctuate over the seasons and are at their lowest levels during the springtime. This is said to influence their bargaining power
