      Yes, and if you read the article, it's clear that the study does not show what it claims to:

      Even though the images flashed up for just 50 milliseconds, roughly the duration of a single frame of standard television footage, their verdicts tallied well with judgements made after a longer period of scrutiny.

      But there is a major flaw. When the image is gone, the participants don't automatically stop making judgements about it.

      50 ms (a.k.a. three refreshes at 60 Hz) is long enough for a person to see something and remember basically what it looks like. In fact, your mind will continue to perceive the image well after the display has gone away. This phenomenon is part of what used to be called 'persistence of vision'.

      So when the experimenters ask the subject a few seconds later what their impression was, and the subject takes a second or two to indicate a preference, this is not necessarily a 50 ms snap judgement. There are whole seconds during which the image was probably being thought about.

      Now, it may be possible that a snap judgement really can be made in 50 ms. But this study does nothing to prove that.

    1. Re:Oh Dear by SnowZero · · Score: 4, Informative

      You are definitely on the right track, though its not clear if its the article summary that's botched or the study itself. Trained cognitive psychologists at least should know better, so I'd lean toward an innacurate summary. The title should probably read "users can judge websites after seeing them for only 50 msec". The "photographic" effect you are referring to is called after-image, and can last long after the initial stimulus is gone. They could make a stronger claim than I stated above if they put up a visual distraction image after the 50 msec (visual memory studies do this a lot). But the summary doesn't mention it so we can't know for sure.

      Regarding human reaction time, it varies depending on the task, but rarely is less than 100 msec (usually when you expect something to happen, such as runners starting a race). That means some tasks can be completed faster than 250 msec thouch, so that's not a good lower bound to quote if you are trying to debunk something. 50 msec certainly is too fast for anything I'd call "judgement" though, as people usually cannot even press a button that fast in response to an event.

      At any rate, the slashdot summary is far from an accurate description of the phenomenon, but since when is that news...

    Probably a way to take better advice from this is to design your pages so they load *FAST* without too many animations, images, and effects.

    What you're referring to is prejudice, or prejudgement. Racism, as defined on wikipedia, is: Racism refers to beliefs, practices, and institutions that discriminate against people based on their perceived or ascribed "race". Primarily, it refers to an assumption that the human species can meaningfully be divided into races, together with hostility to people of certain races or a belief, conscious or unconscious, that people of different races differ in value. Some people whose thinking about others uses racial categories believe that different races can be placed on a ranked, hierarchical scale.

    While prejudice on the other hand is: Prejudice is, as the name implies, the process of "pre-judging" something. It implies coming to a judgment on a subject before learning where the preponderance of evidence actually lies, or forming a judgment without direct experience. Holding a politically unpopular view is not in itself prejudice, and politically popular views are not necessarily free of prejudice. When applied to social groups, prejudice generally refers to existing biases toward the members of such groups, often based on social stereotypes; and at its most extreme, results in groups being denied benefits and rights unjustly or, conversely, unfairly showing unwarranted favor towards others.
