Islam telah lama menyuruh kita menjauhi sebarang perkara yang boleh mendekatkan kita kepada zina. Sekarang saintis barat membuktikan kebenaran tersebut. Kajian dilakukan oleh Dr David Zald, dari Vanderbilt University di Nashville, Tennessee, Amerika Syarikat.
Akhbar, majalah, novel, televisyen, filem malah komik di Malaysia , negara yang majoritinya umat Islam dilambakkan dengan gambar seksi dan ghairah untuk menarik pelanggan yang akhirnya bukan hanya membutakan hati umat Islam , malah membutakan mata kita semua.
Berikut ialah petikan kajian Dr David Zald :
Para penyelidik akhirnya menjumpai bukti apa yang budak-budak Katolik ketahui sejak sekian lama gambar ghairah akan membuatkan anda buta. Kesannya sementara, akan tetapi para penyelidik menggesa kepada pihak majlis keselamatan jalanraya agar mengharamkan papan tanda iklan seksi terutamanya di jalan-jalan yang sibuk, supaya kemalangan dapat dielakkan.
Penemuan terbaru oleh ahli saikologi US itu
mendapati mereka yang melihat gambar ghairah/seksi akan tidak dapat melihat imej yang terpapar selepas itu.
Para penyelidik ini mendapati mereka yang buta akibat rangsangan emosi ini menyebabkan mereka tidak nampak kenderaan lain atau pejalan kaki.

Erotic images can turn you blind

The new study by US psychologists found that people shown erotic or gory images frequently fail to process images they see immediately afterwards. And the researchers say some personality types appear to be affected more than others by the phenomenon, known as emotion-induced blindness.
David Zald, from Vanderbilt University in Nashville, Tennessee, and Marvin Chun and colleagues from Yale University in Connecticut, showed hundreds of images to volunteers and asked them to pick a specific image from the rapid sequence. Most of the images were landscape or architectural scenes, but the psychologists included a few emotionally charged images, portraying violent or sexually provocative scenes.
The closer these emotionally charged images occurred prior to the target image, the more frequently people failed to spot the target image, the researchers found.
We observed that people failed to detect visual images that appeared one-fifth of a second after emotional images, whereas they can detect those images with little problem after neutral images, Zald says.
Primitive brain
We think there is essentially a bottleneck for information processing and if a certain type of stimulus captures attention, it can jam up the bottleneck so subsequent information cant get through, Zald explains. It appears to happen involuntarily. The stimulus captures attention and once allocated to that particular stimulus, no other stimuli can get through for several tenths of a second.
He believes that a primitive part of the brain, known as the amygdala, may play a part. That region is involved in evaluating sensory input according to its emotional relevance and has an autonomic role, influencing heart rate and sweating.
It is possible that emotionally-charged stimuli produce preferential rapid routing of the impulse that bypasses the slower cortical route via the amygdala," Zald told New Scientist. "Patients with amygdala lesions pick out the target image without reacting to violent images, although they show normal blindness reactions when sexual images are introduced, which suggests another mechanism may also be involved.
Harm avoiders
The researchers think emotion-induced blindness could lead to drivers simply not seeing another car or pedestrian if they have just witnessed an emotionally charged scene, such as an accident or sexually explicit billboard.
The effect could exacerbate the more obvious problem of drivers simply being distracted by large, arresting images. "It's the responsibility of drivers to ensure that when they are behind the wheel they keep their eyes on the job in hand," says a spokeswoman from Brake, a UK road safety organisation.
And some people are more vulnerable than others. The study assessed participants using a personality questionnaire, rating them according to their level of harm avoidance. Those scoring highly were more fearful, careful and cautious; those scoring low were more carefree and more comfortable in difficult or dangerous situations.
The researchers found that those with low harm avoidance scores were better able to stay focused on a target image than those with high harm avoidance scores.
People who are more harm avoidant may not be detecting negative stimuli more than other people, but they have a greater difficulty suppressing that information, Zald suggests.
The Brake spokeswoman says companies should think about the consequences of placing emotionally charged billboards at dangerous road junctions: We should be concerned if drivers are experiencing split-second breaks in concentration, which could result in an accident or death on the roads.
