    A few film studies I have watched on The Shining have suggested that these aren't continuity errors at all.. ha ha. It turns out that Kubrick intentionally did a lot of them in the film to create a sense of disorientation and unease. He created impossible sets with bold geometric shapes that were all designed to confuse and again give false representations of the reality of space. Kubrick, OG gaslighter! Its all through through 2001 as well. Great video btw thanks! Im doing psychology of the moving image at uni and this really helped with an assignment :)

    Just several days ago, I was working, wearing a blue shirt. And then at lunch break, I spilled coffee on it, so I went home and changed my clothes to a grey one and then I came back to office. Nobody noticed, even that particular girl who usually comments at everything. Intrigued, here I am, trying to find out what this psychological phenomena is called.

      Maybe you're just not that interesting? It's not necessarily change blindness.

    Not only the shadow of the tree but also a piece of wood at the end of the shadow. The piece appears and disappear along with the shadow.

      And the bush above the shadow

    2:00 AHHH, but did you also notice that the log lying on the ground, next to the shadow, ALSO disapeared?

    Nice demonstration and explanation of the role of a mask in producing change blindness!
    BTW, even a 100 ms mask is enough to produce strong change blindness. The "flicker" screen (often neutral gray) duration that is commonly in change blindness studies is 80 ms, so a bit less, but pretty much equally effective. An interesting question is what the lower bound would be for an effective mask. That probably also depends on the nature of the mask. Given that visual sensory memory has been hypothesized by some to be based on the residual firing of cones after the first stimulus was removed, then any stimulus that would create a different pattern of activation by the cones would suffice. If so, then the lower bound would have to be something too brief, or weak, for cones to respond to. That could be extremely brief, perhaps on the order of 1 ms or less. I don't know of studies that have established this lower bound, but I'm pretty sure they exist, and again, the masking of iconic memory will depend not only its duration, but just as importantly on its visual-spatial nature (e.g., brightness, luminance contrast, spatial frequencies, etc.).

    Thanks for such a thorough and well presented explanation!

    I didn't notice the change in the shadow even with the 0.1 second flicker. I guess that means my sensory memory doesn't even last a tenth of a second.

    The photos on the wall behind Forest at the end are way more dramatic change. While the iron is practically hidden in the video. Rewatching will show you.

    never noticed the ice cube, just the lights flickering throughout the scene

    I missed the shadow change because the mask kept alternating positions on the screen and counted that as the image with one change, so stopped looking.

    i saw the change in the first example but not the second 🤦🏾‍♀️

      I had the opposite, didn’t see anything in the first but i did in the second

    And what about the stick on the ground? That’s what I saw 😂

    In the shining he also takes a scoop of nuts to eat, and there are still a few in the glass. Unless I’m mistaken then there are none in the next shot
