Inattention Blindness Test

Hi Speed

You Have “Inattention Blindness”
First let’s start with a little test for you to take. Watch the video below.

This is an example of what is called “inattention blindness” or “change blindness”. The idea is that people often miss large changes in their visual field. This has been shown in many experiments.
Remember, just because something happens in the visual field doesn’t mean that people are consciously aware of it.

Hi Speed

Creative clothing made from condoms popping up all over the internet in such versatile and surprisingly beautiful styles, we have to wonder – could condom garments be an innovative new eco-fashion trend? And would you actually be willing to wear prophylactic couture?

Photos of wild Stallions Fighting

01:29

Hi Speed

This is the dramatic moment two proud stallions faced off in a bloody fight for dominance and mating rights in a herd of wild horses.

The Koniks, or Polish primitive horses, reared up on their hind legs with their teeth bared during the ferocious attack.

Photographer Henri Ton, 41, captured the fight over females at a nature reserve in Loevenstein, The Netherlands.

One stallion could be seen chasing a mare while others fought among themselves.

Mr Ton, who works as an electronic engineer, spends several hours a week observing the herd of 36 horses to better understand their behaviour.

He said: 'The Koniks were put in a nature reserve and left to fend for themselves.

'The public are told to keep their distance and not to feed them so they can remain wild.

'I go looking for them about once a week and have done for over a year now.

'I try to avoid attracting their attention so their behaviour in my pictures is as natural as possible.'
Dominance: Teeth bared, the two horses continue to fight as other members of the herd watch on in the background.

Fierce: Polish primitive horses were introduced into a nature reserve in Loevenstein and have begun to thrive

The battle among the Koniks, or Polish primitive horses, took place at a nature reserve in Loevenstein, The Netherlands.

He said the herd is formed from a mix of bachelor groups - young stallions who have been abandoned or rejected and need to play to build up their strength before returning - and harem groups which feature one stallion, around six mares and foals.

There is one lead stallion in the herd, which is the only male allowed to breed.

'Fights with the lead stallion can be very rough and if he is injured the other stallions try to take over.

'Sometimes it is playful, almost like an act or dance, but it can also be very aggressive with bloody injuries.

'The Konik horse is one of the few types of horses able to survive in the wild. They are wild but they have never been aggressive towards me.'
