Visual processing of pictures

Word responses have been used to dedde whether pictures of expressive faces or postures portray truthful expressions. Previous investigators have assumed words are used only as symbols of “meaning”. They did not appreciate the use of words as symbols of “sorting”. If one viewer calls two photographs “angry” and another viewer calls the same two photographs “happy,” the viewers may disagree in their “meanings” but they agree in their ‘sortings” both agree each photograph portrays the same expression. Sorting groups reveal how the visual system processes photographic images.
