Men lose their minds speaking to pretty women

The research shows men who spend even a few minutes in the company of an attractive woman perform less well in tests designed to measure brain function than those who chat to someone they do not find attractive.

Researchers who carried out the study, published in the Journal of Experimental and Social Psychology, think the reason may be that men use up so much of their brain function or ‘cognitive resources’ trying to impress beautiful women, they have little left for other tasks.

The findings have implications for the performance of men who flirt with women in the workplace, or even exam results in mixed-sex schools.

Women, however, were not affected by chatting to a handsome man.

This may be simply because men are programmed by evolution to think more about mating opportunities.

Psychologists at Radboud University in The Netherlands carried out the study after one of them was so struck on impressing an attractive woman he had never met before, that he could not remember his address when she asked him where he lived.

Researchers said it was as if he was so keen to make an impression he ‘temporarily absorbed most of his cognitive resources.’

To see if other men were affected in the same way, they recruited 40 male heterosexual students.

Each one performed a standard memory test where they had to observe a stream of letters and say, as fast as possible, if each one was the same as the one before last.

The volunteers then spent seven minutes chatting to male or female members of the research team before repeating the test.

The results showed men were slower and less accurate after trying to impress the women. The more they fancied them, the worse their score.

But when the task was repeated with a group of female volunteers, they did not get the same results. Memory scores stayed the same, whether they had chatted to a man or a woman.

In a report on their findings the researchers said: ‘We conclude men’s cognitive functioning may temporarily decline after an interaction with an attractive woman.’

Psychologist Dr George Fieldman, a member of the British Psychological Society, said the findings reflect the fact that men are programmed to think about ways to pass on their genes.

‘When a man meets a pretty woman, he is what we call ‘reproductively focused’.

‘But a woman also looks for signs of other attributes, such as wealth, youth and kindness. Just the look of the man would be unlikely to have the same effect.’

Humongous Earthworms

Is this real? If you have the stomach, click on the image to head to an image gallery and our very ordinary investigation.

So, are these photos real? And the answer, amazingly is… probably yes.

Here in Brazil we have our very own Minhocuçu (Rhinodrilus e Glossoscolex spp) which can easily grow beyond half a meter in length an almost an inch in diameter.

And it’s not by far the longest earthworm recorded.

The Microchaetidae family in South Africa is a group where all species can reach over a meter in length. This is no folk tale or cryptozoological rumor: specimens of this size have been duly recorded for over a century already.

And even those are not the champions. The title goes to the Megascolecidae family from Australia. The record: 2,1 meters by 24 millimeters thick.

The worms in the images all look they are up to a meter in length, compatible with the recorded dimensions for the many species of the families we discussed. They are probably real, though exactly from where and what species my ordinary investigation didn’t come up with. Specialists, do enlighten us with further confirmation and identification! The first image of a girl holding up one, for instance, may not be of an earthworm but of is a caecilian.

Giant earthworms are harmless, but perhaps because of their plain appearance and our instinctive disgust of them all kinds of legends are associated with them, even in places where we can’t find those “little” couple-meter-earthworms.

The most curious legend is not exactly about an earthworm, but of a worm. A death worm. The Mongolian Death Worm. It can allegedly kill its victims by either spraying a lethal and blinding venom, or sending electrical discharges.

In Brazil, where we do have our Minhocuçus, there’s also the legend of Minhocão, 25 meters in size. Like the Mongolian Death Worm, its not very plausible such a creature exists.

Earthworms over a couple of meters in length are real and they can more than make up for a mix of disgust and fascination. Not only they can harm nobody and are actually important part of the ecosystem, in Brazil they are in danger as they make really excellent fishing bait. This is no joke (link in Portuguese).

UPDATE: Identified! Well, at least the where and who for the second photo. It’s from Lisa B, available on her flickr account. As Lisa wrote in the comments below, “that image was taken in the Bellavista Cloud Forest Reserve in Ecuador, and it is indeed a real worm.” Thank you! Apologies for not including credit beforehand, I reproduced the original gallery from erueru, linked below, and I’m happy to include the sources.
