If IB in the earlier studies and in this replication were due to some oddity caused by the transparent displays, then subjects should easily detect the umbrella woman and gorilla in these opaque conditions. However, they did not, as approximately 35% of subjects did not see the fully visible umbrella woman and gorilla. In one extra condition, the opaque gorilla stopped halfway across the display, turned to face the camera, thumped its chest, and then exited on the other side of the screen. Even in this condition, half of the observers did not see it. In the static IB paradigm, observers often fail to notice the onset of a new, un ...

    Digital photography, which is also called digital imaging since it does not involve the use of film started in the sixties. The original development of the technology is at NASA when they required that exploration spacecraft, unable to return to earth, to be capable of sending back pictures of their voyages. The digital camera, like the standard film camera, uses a lens to focus the image on a sensor. The usual film camera depends on a film to capture the image but the digital relies on a sensor, either CCD or CMOS . As light hits the pixels that make up the sensor, it is converted to a current that is then sent to the Analogue to Digital Converter or A-D converter. When a photo is digitised ...

  • King Lear Vision - 1,379 words
    King Lear Vision In Shakespeare's tragedy, King Lear, a prominent reoccuring theme is vision and its relovence. The characters, Lear and Gloucester are Shakespeare's principal means of portraying this theme. Although Lear can physically see, he is blind in the sense that he lacks insight, understanding, and direction. In contrast, Gloucester becomes physically blind but gains the type of vision that Lear lacks. It is evident from these two characters that clear vision is not derived solely from physical sight. Lear's failure to understand this is the principal cause of his demise, while Gloucester learns to achieve clear vision, and avoids a fate similar to Lear's. Throughout most of the pla ...

    ... the nausea and vomiting that go along with certain cancer treatments. Another chemical related to THC (nabilone) has also been approved by the Food and Drug Administration for treating cancer patients who suffer nausea. The oral THC is also used to help AIDS patients eat more to keep up their weight. Scientists are studying whether THC and related chemicals in marijuana (called cannabinoids) may have other medical uses. Some think that these chemicals could be useful for treating severe pain. But further research is needed before such compounds can be recommended for treatment of medical problems.
