Could signallers use size contrast illusions to dishonestly exaggerate their attractiveness to potential mates? Using composite photographs of women from three body mass index (BMI) categories designed to simulate small groups, we show that target women of medium size are judged as thinner when surrounded by larger women than when surrounded by thinner women. However, attractiveness judgements of the same target women were unaffected by this illusory change in BMI, despite small true differences in the BMIs of the target women themselves producing strong effects on attractiveness. Thus, in the context of mate choice decisions, the honesty of female body size as a signal of mate quality appears to have been maintained by the evolution of assessment strategies that are immune to size contrast illusions.
Our results suggest that receiver psychology is more flexible than previously assumed, and that illusions are unlikely to drive the evolution of exploitative neighbour choice in human sexual displays. Previous article in issue. Next article in issue.
Description Presented here is a vast gallery of many different forms of Optical Illusions. Whether these optical illusions are conveyed through fractals, photographs, architecture, art, or old fashioned pen and ink, they are bound to remind you that 'seeing is not believing.' Some of the optical illusions on this blog may cause dizziness or possibly epileptic seizures. The latter happens when the brain can't handle the conflicting information from your two eyes. If you start feeling unwell when using this website, immediately cover one eye with your hand and then leave the page. Do not close your eyes because that can make the attack worse. I don't know how many of you have seen on the Sci-fi channel.
I have been watching it and they follow a group called (The Atlantic Paranormal Society) that investigates sites to disprove hauntings. Occasionally though they come across evidence that they can't disprove or provide an explanation for.They set up cameras and record audio and video then afterwards they return to their home base where they examine every second of the video and audio to see if anything happened.
They have picked-up voices from people that weren't there and chairs moving on their own.What I am about to link to is not from this group but is of a similar ilk. There is about 60 seconds of video of a well lit room(even more amazing this was during the day). What the cameras picked up may scare you or amaze you. If you listen close and pay attention to the screen I think you may be able to pick up on the sound of what may only be referred to as a ghost and an image that seems to come out of no where.The only thing I don't like about this is that they could have edited it better. Although the sound (while quiet) can be heard early, the image doesn't appear for about 38 seconds.If you still wish, go to and tell me what you think?Is this real proof of live after death? 53comments:Johnnysaid.That scared the shit out of me.
