|This article is/was the subject of an educational assignment in Fall 2014. Further details are available on the course page.|
|This is the talk page for discussing improvements to the Perceptual adaptation article.|
Why is this article visible to the public? One paragraph in the "Effectiveness in compensating for alterations in the visual field" section is repeated over twenty times. --Gary S. Hart (talk) 15:54, 20 December 2012 (UTC)
- Schoolkid vandalism from yesterday. Thanks for catching and fixing. NawlinWiki (talk) 16:01, 20 December 2012 (UTC)
The content is very repetitive. As stated on the talk page, certain phrases and sentences are unnecessarily repeated in such a short article. Another big issue is the way this article is written, instead of being informative and unbiased, it sounds like personal opinions. Shelby.a.schields (talk) 22:07, 6 October 2014 (UTC)
As Shelby mentioned, the article appears biased and is very repetitive. Additionally, is does not talk about any current research and does not provide any examples or discussions about the applications of perceptual adaptation or any research done on the subject.

- Add images, photos, graphs, etc.
- Make page more visually appealing --- I can work on points 1 and 2 here KatVoronova (talk) 14:20, 17 October 2014 (UTC)
What would be some good images to include? We can think of ideas and I can work on looking for images and adding them to the article. Any images/experiments you think should be included? KatVoronova (talk) 15:33, 7 November 2014 (UTC)
- Connect to other research and link to articles on that research, if applicable
- Insert a conclusion section
- Re-write the other sections to reduce the repetitiveness.
- Broaden the topic beyond just senses --- I can work on 2 and 3. I think this would be a good group effort to make the article as best as possible KatVoronova (talk) 14:20, 17 October 2014 (UTC)
- Add current research --- I can work on this for face recognition, vision, and some other articles I have found KatVoronova (talk) 14:20, 17 October 2014 (UTC)
- Add information about other senses like hearing
- Link this article to others in wikipedia
Intro: Perceptual adaptation is the idea that when one’s visual field is altered (e.g., when images are shifted to the left or right from their normal locations while wearing special glasses, which will be discussed later) one’s brain adapts to these new perceptions automatically and unconsciously in the visual field.  Shelby.a.schields (talk) 18:26, 6 November 2014 (UTC)
Perceptual adaptation is a unique function of the brain that accounts for the differences viewed in the world, most specifically in vision. Images sensed through the eyes are relayed to the visual cortex of the brain, and if vision is altered slightly, the brain accounts for the difference and will allow one to perceive the world as "normal." This is a compensation mechanism the brain uses for the world to appear normal in our minds. For example, the brain responds to a change in perceived vision when glasses are worn to distort images any subject sees by forty five degrees. Over time, the brain processes the acute difference as normal. As a result of this adaptation, the brain makes to this difference in perception, the subject, with the glasses, is able to perform daily tasks as before the glasses were applied. Contrary to perceptual adaptation, if the distortion in vision is repealed, then the brain will perceive images as when the distortion was first applied.

Herman Helmholtz, a distinguished scientist from the 1800s, thoroughly researched conscious sensations and how they converted into meaningful perceptions of events. He defined sensations as the "raw elements" of conscious experience that required no learning and perceptions contrarily as the meaningful interpretations he gave to senses . He studied the physical properties of the eye, color vision, and visual perception including perceptual adaptation. One of his classic experiments regarding how space perception could be altered by experience involved participants wearing certain glasses that distorted the visual field several degrees to the right of the normal location. Participants were asked to look at an object, close their eyes, and try to reach out and touch it. At first, the participants understandably reached to the right of the object, but over time perceptual adaptation occurred and they could consciously place their hands to the left in order to touch the objects. After some time, this action became automatic and natural. Helmholtz also theorized that this phenomena could also result from unconscious inference.

According to Rhodes (2010), individuals can become adapted to a face as early as after five minutes of looking at it. Individuals become accustomed to the features, grouping similar features together. This type of visual perceptual adaptation frees up sensory systems, vision in this case, to focus on other, more unique traits, using them to recognize faces on a case-by case basis. KatVoronova (talk) 14:26, 7 November 2014 (UTC)
Webster (2011) looks at visual adaptation more broadly, not only focusing on faces. She mentions that visual adaptation occurs on both higher and lower levels of visual pathways, and vision is, in fact, highly adaptive, despite previous beliefs that it is not. Lastly, it is interesting to know that we still do not know why visual coding adapts. KatVoronova (talk) 14:26, 7 November 2014 (UTC)
- Cite secondary sources to broaden and update the current research
- Give specific experiments that deal with this topic (Face Recognition, etc.) KatVoronova (talk) 14:14, 17 October 2014 (UTC)
Sekiyama (2012) did research about the adaptation to reversal after individuals wore reversing prism spectacles long term, roughly 35 days. INdivuduals responded to visual-motor and somato-visual stimuli once wearing the spectacles, as time went on the had ore correct answers, similar to Helholtz. After the glasses were removed an MRI was done and Sekiyma found "perceptual adaptation to reversed vision does occur, and that it proceeds to visuo-somatosensory reorganization, which seems to transiently accompany global cross-modal interactions."Kileysmith (talk) 15:42, 7 November 2014 (UTC)
Perceptual Adaptation helps us identify faces.
Face Adaptation Improves Gender Discrimination
Adaptation and visual coding by M. Webster http://www.journalofvision.org/content/11/5/3.short Perceptual adaptation helps us identify faces by G. Rhodes et al. http://www.sciencedirect.com/science/article/pii/S0042698910001185 The Journal of the Acoustical Society of America has a lot of interesting articles related to perceptual adaptation. KatVoronova (talk) 14:18, 17 October 2014 (UTC)
I can work on the research related to face recognition and some other related experiments, as well as rewriting the existing info and making it more condensed. KatVoronova (talk) 14:18, 17 October 2014 (UTC)
After reviewing the new information put in here by others, I will be finding new research since some of my old sources do not fit the definition in the introduction, since this is specific for vision. I will be finding more current research about vision to include on this page instead. I will be looking up studies that used prism adaptation as well since this is often used to alter vision. Kileysmith (talk) 15:30, 7 November 2014 (UTC)
I found this new article about the reorganization after vision was reversed: http://web.a.ebscohost.com.ezproxy.lib.ndsu.nodak.edu/ehost/detail/detail?vid=5&sid=54779ea8-a18f-4adf-b3ce-b1b4da0f6885%40sessionmgr4003&hid=4114&bdata=JnNpdGU9ZWhvc3QtbGl2ZSZzY29wZT1zaXRl#db=aph&AN=82200670 Kileysmith (talk) 15:30, 7 November 2014 (UTC)
You guys have done a great job working together on this part of the assignment! Time to start developing the article. Yes Kiley, remember to log on and sign your posts to get credit. J.R. Council (talk) 22:33, 22 October 2014 (UTC)
- Just a couple of other things.
- I can't see where Shelby has indicated which sections she'll be working on.
- There is a section in the textbook that describes work Helmholtz was doing on perceptual adaptation back in the 1800s.
Feedback for Assignment 9
General comment: You’ve added content to the main article, but it is still pretty sketchy. The banner on the top that warns of multiple issues still holds – needs a lot of improvement. You have a lot of good information and ideas sitting on the talk page. Time to move all this to the main article. Comments on Specific Sections:
- Perceptual adaptation can occur in other senses besides vision. Need to reword first sentence.
2. Experimental support
- This section could be expanded a lot. As I commented before, Helmholtz was working on this in the 19th century.
- Add citation for Stratton’s later study.
- Try to find acceptable image for goggles.
3. Potential alterations to the visual field
- The title of this section doesn’t make much sense.
- Also, what does this phrase mean? “fashion the subject with glasses”
4. Research on Perceptual Adaptation
- Move 3 preceding sections to this major section. (Experimental support Potential alterations to the visual field, Effectiveness in compensating for alterations in the visual field) These sections were also about research.
- Need more specific instructions for Lilac chaser. Have to fixate on cross in center in order to experience effect.
