[edit] Comments

EntmootsOfTrolls would have liked this article to be part of User:EntmootsOfTrolls/WikiProject Body, Cognition and Senses, which provides guidelines for articles on those topics, and seeks stronger cross-linkage and cross-cultural treatment of all of these topics.—The preceding unsigned comment was added by 142.177.92.68 (talk • contribs) 01:08, 24 September 2003 (UTC).

[edit] Can be psychologically studied

Visual Perception falls under the auspices of psychological study so long as it is studied from a psychological perspective. Clearly it can be studied from many points of view, and I know so many psychology professors who work on this multidisciplinary subject that to not list it would almost seem laughable to me. I thought the article conveyed pretty well that it can be (and IS!) psychologically studied. --ABQCat 09:15, 10 Oct 2004 (UTC)

[edit] categorization

I removed the psychology category, because its redundant. Visual perception is a part of psychology through the 'perception' subcategory.

"An article should not be in both a category and its subcategory, e.g. Microsoft Office is in Category:Microsoft software, so should not also be in Category:Software." -- Wikipedia:Categorization

--Johnkarp 09:29, 10 Oct 2004 (UTC)

Then remove it from the "perception" category or something. It's clearest and easiest to find by browsing through a list of psychology category items. Common sense should also always prevail, despire wikipedia guidelines. --ABQCat 11:06, 10 Oct 2004 (UTC)
I agree we should go along with common sense. But I'd be interested in hearing exactly why you believe visual perception should be a top-level subject under psychology, and referring to 'common sense' doesn't communicate anything.
What I'm trying to do is have a simple, clear Psychology category system, where related subjects are clustered. If people are looking for visual perception, they're going to type it in directly as 'visual perception' or 'perception' and get there directly without using categories. If they're browsing, they want related subjects. Now psychology is a really big field, so having everything related to psychology in one gigantic pile I don't think is helpful. For example, finding visual perception among 'illusions' and 'gestalt' is helpful, whereas finding it among 'vicarious conditioning' and 'vulnerability theory of schizophrenia' is not.
My conception of how the psychology should work category-wise is have sub-categories for the schools (behaviorism, cognitivism, etc.) and divisions (social, cognitive, personality, perception, etc). Most individual subjects would fall under at least one of these groups, and not need to clog up the parent psychology category. The subjects directly listed in psychology would be fundamental issues in psychology, such as research techniques.
I think this conception agrees with the conventions here on Wikipedia. For example, Napoleon is listed under Category:French_heads_of_state, but not directly under Category:French_politicians, even though Napoleon is a very notable French politician. If you want to break the conventions of Wikipedia, you should have a good reason you can clearly explain.

I can't say that I'd see any problem with such a categorization scheme. I do think that perhaps there should be a recursive link to navigate upwards within the nested category schemes. Perhaps something along the lines of [[Category:Perception]], a subtopic of [[http://en.wikipedia.org/Category:Psychology|Psychology]] or some such. Something analogous to directory browsing with a fully qualified path statement, if you get my meaning? Not sure how well this could be implemented with the current method of listing categories at the end of the page, but I think it would be useful for those who stumble instead across "Visual Perception" and are interested in topics related to it. It has relationships to areas of psychology which are just as valid as relationships to other perceptual modalities. --ABQCat 21:47, 10 Oct 2004 (UTC)
Infobox for psychology looks good to me. If there are any improvements other folks want to make to it, that'd be fine, but I think it's clear, succinct, and makes obvious how visual perception fits into psychological studies. --ABQCat 07:00, 11 Oct 2004 (UTC)

[edit] Illustrations !

Isn't it paradoxical that an article on visual perception has no illustration whatsoever ? Pictures would really help explain unconscious inference, Gestalt laws, etc. If anyone feels like sketching up a few doodles, here's a great opportunity. Sbarthelme 11:30, 11 May 2005 (UTC)

There's currently a photograph of a pair of eyes on the right-hand side of the article overlapping and obstructing the text of the article itself. I tried several times to change the alignment of the image, but I couldn't figure out how to prevent the overlapping effect. Would any of you wiki-savvy users be willing to correct this glitch?.—The preceding unsigned comment was added by 65.25.231.4 (talk • contribs) 05:08, 8 August 2005 (UTC).

At the current moment, I see nothing wrong. If someone can duplicate this error, reply here with your browser+version.--M1ss1ontomars2k4 23:51, 7 May 2006 (UTC)

On the other hand, why include illustrations if they add nothing to the article? I'm particularly talking about the picture of 'human eyes', which seems completely pointless. 163.1.143.162 (talk) 17:07, 4 March 2008 (UTC)

I completely agree. Also the illustration "The visual dorsal stream (green) and ventral stream (purple) are shown. Much of the human cerebral cortex is involved in vision." should be moved to another place. I could upload an illustration of the human eye by Leonardo DaVinci. --Hans-Werner34 (talk) 13:14, 24 April 2008 (UTC)

[edit] A Primer on Probabilistic Approaches to Visual Perception

I removed that paragraph because it was copied from http://www.purveslab.net/research/. Unless that piece of text is copyleft we can't use for this article. Also sounds a bit like self-prom.

I linked to it in the "unconscious inference" paragraph. Sbarthelme 17:58, 3 April 2006 (UTC)

I removed it again. Medtopic 06:47, 2 June 2006 (UTC)

[edit] Removed from article

Unsourced and addresses the reader:

Up to 90% of information obtained by humans is from their vision. This is why people with eye problems struggle more than other conditions of the other senses because seeing is so common that people take it for granted but the simple tasks of walking down the street or taking a bath seem much harder when you think about that you can't see what you're doing.

[edit] Merge

Underwater vision appears to be an essay or such. I believe the article would be better suited being merged into this article (Visual perception). --Midnightcomm 17:59, 29 August 2006 (UTC)

They should stay separate - the merge is not required as the topics are disparate. Visual perception is about photochemistry, neurological and psychological aspects of vision in humans. Underwater vision is a physical concept of visual distortions expected for aquatic life and divers - it is of sufficient scientific interest to deserve its spot on Wikipedia.

[edit] "See also" section

Anyone else think the "See also" section is getting out of hand? -AED 23:10, 20 October 2006 (UTC)

Yea, it seems that most of those topics currently in the "See also" section would be more appropriately linked through content in the article. Privong 03:34, 22 October 2006 (UTC)

[edit] Human Visual System

The 'visual system' section repeats information found easily elsewhere - if people want detail they can follow the links. I don't think that this should be the focus of this article. Famousdog 13:16, 11 April 2007 (UTC)

[edit] Computer vision category

I removed this article from the computer vision category. VP is already listed under the vision category which is linked to the CV category. --KYN 16:27, 28 July 2007 (UTC)

[edit] Study?

Wasn't there some sort of study where a group were asked to wear special glasses that flipped their vision upside down and after a while their brain caused the image in their head to flip back to normal perception and then when they took the glasses off the image was upside down again until their brain adjusted again? That was a long sentence, but if that study was real I think it is very pertinent to this subject and should be added...in addition to being extremely interesting. Chitchin13 (talk) 02:32, 7 May 2008 (UTC)

The initial study was published in 1896: G.M. Stratton, Some preliminary experiments on vision without inversion of the retinal image. Psychol. Rev. 3 (1896), pp. 611–617. A more recent paper on the topic is here: [1] Famousdog (talk) 13:44, 7 May 2008 (UTC)
