WTF
is this article for real? delete (or move to uncyclopedia)! "Well known leaders of the free world are tested using Microexpressions when elected." any source for that? :) —Preceding unsigned comment added by 80.217.63.138 (talk) 00:47, 27 January 2009 (UTC)

WTF? Microexpressions will be red hot as we get to the next plateau of understanding human interaction. There was a WIRED article from 2003 - http://www.wired.com/culture/lifestyle/news/2003/09/60232 and from Science Daily in 2006. Granted, not as prestigious as the SIGGRAPH Proceedings, but not total psycho-babble. Neologism? When was the word neurophysiology coined? I just read about them in the book - Neuroscience of Human Relationships - I can't find the reference right now... Microexpressions will be well documented hard science in the near future. Wikipedia can be a little patient with the public misgivings and stay on the right side of science or a bunch of loopy luddites. Don't you need to impeach Paul Ekman before deleting? BTW, the above offending line is no loner there.

Microexpressions may be an up and coming area of scientific inquiry, but at the time this really seems more like the pet project of one person, or perhaps a few people. I imagine there must be studies that refute the idea of microexpressions, seems there should be a section on criticism or controversy regarding the subject.Mad05963 (talk) 00:03, 14 April 2009 (UTC)
 * Yes, where is the criticism? Seems like this subject is mostly supposition; while there may be similarities amongst cultures, 'universality' of expression is a long way from proved. Impeaching Ekman may not be needed, but according to his Wiki-entry, take note he was funded by an on-going gov't grant for most of his career, as many of these 'ivory tower' academics are. 66.81.252.120 (talk) 23:42, 7 June 2015 (UTC)

Truth Wizards
This line "Science calls these people 'Truth Wizards'" seems... well, unscientific. Science doesn't call anyone anything. Scientists do however, this line should actually stste who coined the term.Mad05963 (talk) 00:03, 14 April 2009 (UTC)
 * I agree. I'm removing this line because it obviously seems incorrect to say 'science calls them...'. Moreover, no citations given. Ankur Banerjee (talk) 16:51, 17 April 2009 (UTC)

Botox Section??
The Botox information is interesting, but fills the majority of the entry, which is not about Botox. It could use more integration/justification and balance by other information. WHY does it matter that botox can do this? Is it used to hide lies, or has it been used in research into microexpressions? The only connection I've found in searches are silly comments in threads discussing the research and a question/answer pair in an interview with the researcher. I'll try to clear this up when I can.Bigdoglover


 * It is also a vast oversimplification of the neurology to the point of being misleading. Different neural pathways are not linked to different motor nerves but will lead (in some way we don't understand) to different patterns of motor nerve excitation.  The black box of how different neural pathways might lead to different motor patterns is a huge gap in our understanding, as is the understanding of what, exactly, different neural pathways are.  What is probably going on in Botox is that both the microexpressions resulting from "truth-telling" and the microexpressions resulting from "fiction-telling" are distorted ("blurred" in effect) due to the lack of sufficient activation of certain muscles, thus inhibiting the ability of another person to accurately decipher them.  In either case, our knowledge on this subject is conjectural at best.  I would recommend removing the Botox section altogether, as it is both misleading and unnecessary. dwinetsk


 * Thanks for the info dwinetsk, I have used it to clarify the language in this section. Could you provide the sources for your info and add them to the article? Dr.Crawboney 11:54, 31 Octover 2006 (UTC)


 * There is a Discover magazine article about how Botox does reduce anger (as it paralyzes the face). So... --Heero Kirashami (talk) 00:54, 25 January 2009 (UTC)

"microsecond to microsecond"??
The statement "American psychologist John Gottman began video-recording living relationships, microsecond to microsecond, to study how couples interact." can't possibly be correct.

A microsecond is a millionth of a second. Video is typically 24 (or is it 30?) frames per second, or if you prefer, on the order of 30,000 - 40,000 microseconds per frame. Even if one could actually capture a million frames per second, it is highly unlikely that this would be useful. More likely, the image would not change at all for thousands of frames (milliseconds) at a time. Poring through a million frames in order to parse a second of interaction also seems incredibly time-consuming.

Anyway, it's pretty clear this is just a typo. The relevant question is, what time scale was Gottman actually using? -Dmh 17:15, 10 November 2006 (UTC)

Does the time scale really matter? It's most likely somewhere between 1/20th to 1/30th of a second (nowhere near a microsecond), but is that really relevant? I'm going to delete the part about microseconds. Snottywong 01:52, 2 October 2007 (UTC)

Here is a citation for the 1/25th of a second statement. http://www.youtube.com/watch?v=IA8nYZg4VnI#t=36m00s Source is an interview with Dr Ekmen, The creator of the Facial Action Coding System94.168.208.190 (talk) 18:40, 18 July 2010 (UTC)

Actually, Dr. Ekman says that it's 1/15th to 1/25th a second that a Microexpression can occur. Here is the citation to prove what he says: http://face.paulekman.com/aboutmett2.aspx froggy26rk (talk) 06:50, 28 August 2010 (UTC)

It's worth pointing out (here on the Talk page) that analysis of microanalysis of film was in place by the mid-teens by the Gilbreth's with inconsistent frame rae (circa 16fps). By the 30's Arnold Gesell was working at 24 fps and folks like the Palo Alto group through the 60s were at that frame rate. Video is 30 frames a second and microanalysis of microexpressions is stuck with that granularity. When audio is analyzed or a SMPTE code was used with video, much finer temporal decisions could be made, however, given that the microexpressions are encoded in the image data, it is difficult to talk about doing timing that's very good given standard recording equipment. It is relevant, then, to note that the expressions under discussion can be ridiculously brief and the sensors used to capture them need to be better than standard fare. Sadly, that's typically not the case.

The Diogenes Project?
I'm pretty sure the link to "the Diogenes Project" isn't the intended link -- the Diogenes to which it is linked is Diogenes of Sinope, which while a fascinating article, seems to have little to do with microexpressions. Sadly I think that either the link has to be removed, or some more research has to be done and a Diogenes Project stub created.--Iknowyourider (t c) 18:49, 17 June 2007 (UTC)

Hey i'm new to this thing, but i added some square brackets, because i want to study microexpressions, and at some point whatever i write should be linked to you. So yeah, if i've done something wrong. Je m'excuse :p But, i'm still learning the inn's and outs of this thing. —Preceding unsigned comment added by ToasterCoster (talk • contribs) 05:34, 27 December 2008 (UTC)

People who daydream while you talk
What if the person you're talking to is daydreaming? Wouldn't the microexpressions you see be mis-attributed to what you're talking about? Jigen III (talk) 06:32, 16 April 2010 (UTC)


 * I'm under the impression that if you were daydreaming the fact that your attention is elsewhere would also be detectable - But I have no sources Basiclife (talk) 08:51, 14 May 2010 (UTC)

MERA non profit organisation
I'd like to include a piece of information about Micro Expressions Research Association to the article : MERA (undone article history) (Note the MERA section) howether it gets moderated. I've read and learned a lot about micro expressions, and the association I added seems adding value to the article on wikipedia, because it has links to more articles and relevant resources, what is useful for the readers. It's a non-profit organisation and it's not spam, so I don't understand why you removed it. I beleive what I found there does contribute to more information about research and micro expressions. Can you redo the changes or let me know how it's more approriate to contribute with this resource? — Preceding unsigned comment added by Microexpress (talk • contribs)


 * The text you tried to include says nothing about the subject of this article and is therefore highly off-topic here. The text merely says something about a certain organisation with, by the way, a website that is not even accessible without registration. - DVdm (talk) 10:09, 17 October 2012 (UTC)

Amygdala
Would it be possible to leave the amygdala out of this?

People love to point to the amygdala when they talk about the brain and emotions but, truth be known, there's much more of the brain involved than the amygdala. You could look to the cingulate gyrus, the septum, the hippocampus; you could talk about the limbic system or Papez circuit. The Amygdala is the Marsha Brady of the emotional brain. It gets all the attention. Amygdala, Amygdala, Amygdala. I'm trying to be light-hearted about this and hope it doesn't come off as offensive. I don't mean it to be. I mostly wanted to note that while the amygdala performs an important role, it is part of an ensemble cast and that while removing it would have a deleterious effect on microexpressions, so would removing any number of other related structures. Important recent work on the neuroscience of emotion by Lisa Barrett is a real game changer and does not give this solo role to the amygdala. That said, the game even before this game changer didn't privilege the amygdala like this article.

I wonder if the person who wrote that section might want to defend their choice. I won't go in and change it as I'm knowledgeable but not an expert. Perhaps someone knows of expert opinion that would support the claims. I don't. — Preceding unsigned comment added by RichardBeckwith (talk • contribs) 00:41, 10 December 2019 (UTC)

I'm no expert either, but the parenthetical identification of the amygdala as "the emotional center of the brain" reads like a lie-to-children on the order of magnitude of "the mitochondria is (sic) the powerhouse of the cell." It's also tangential enough that deleting it would not hurt the paragraph even if the paragraph's exclusive identification of the amygdala as the source of microexpressions is 100% accurate. 35.40.127.104 (talk) 17:22, 10 February 2020 (UTC)

History of Microexpressions
The history section references "discovery" by 20th century studies of the subject. I personally witnessed and heard discussion of micro expressions used in ancient Khmer political art at Angkor Wat and in Khmer dance in modern day Cambodia. It was explained to me by a local guide long before the referenced discovery that micro-expressions were used in Khmer sculpture and dance by the ruling elite to communicate the desires of rulers and to control behavior of the masses. I suggest that there needs to be some more research about the history of "discovery" rather than strictly crediting such recent study. — Preceding unsigned comment added by 2600:8800:4980:1FBD:A98C:D612:BCA8:BAD2 (talk) 05:13, 28 January 2020 (UTC)
