Self -consciousness is a person's consciousness of his physical and mental state and the relationship between himself with the objective world，Its development process is a process of continuous socialization，is a process formed by personal characteristics，It is also an important part of the person's personality structure，It is a self -regulating system in a personality structure。Therefore，Good self -consciousness has a vital role in forming a good personality of people。2002，Psychologist Philippe Rochat and Tricia Striano thinks，Self -facial recognition is an important indicator of self -consciousness，It is important for the development and understanding of self -awareness。

Face is our unique physiological characteristics，Have a very close contact with yourself。2003，psychologist Julian P. Keenan and others believe that，Different from other self -related information，Self -faces are not shared with others，It has uniqueness and specificity。2006，Serge Brédart and others proof，Face is the most unique part of our body，It has become a symbol of self。2011，Researchers from Christel Devue and others，Self -face recognition has different neurological indicators。Therefore，A large number of psychological experiments conducted behavior and nervous research on self -facial recognition。

A large number of behavior research provides reliable evidence for the advantages of self -facial recognition。2008，Du Wen et al. Research on self -facial recognition discovered the advantages of self -facial recognition，That is, when people have more attention to their Bet365 lotto review faces and respond faster。2010，Oliver Hirsch and others discovered，Even under the condition of the launch of the threshold，Test will also recognize self -faces faster。2013，Hu Yuanyan and others have also discovered the relationship between self -esteem and face recognition，That is、Parents' faces and celebrity faces have more attention，and low self -esteem have the same attention to all faces。

other，Eye movement also found the advantages effect of self -facial recognition。2008，Du Wen and others discovered，Eye reaction of self -facial recognition is faster than others face recognition，less eyes jump。2011，Heinisch Christine and others studied at the study，The recognition of self -faces needs to be positioned from a decentralized position to self -position，and show high attention to self -related stimuli，There are more gaze points for self -faces。2012，Clara J. HUNGR and others studied discovery，Compared with the stimulus different from the self -faces，Stimulation similar to self -faces has a stronger gaze effect。To examine the visual processing of whether there is similar to the face and familiarity with the face，2017，Chakraborty Anya and others also use themselves — others' face recognition paradigms to examine what kind of gaze response mode does the subject's face and face that belongs to others。As a result, I found，When the overlapping reduction between self and others' facial representation，People will spend more time to observe the upper area of ​​being recognized as a self -facial face。

In addition to the research on health testing and found the advantages of self -facial recognition，Researchers' research on patients with mental illness or dysfunction also discovered this effect。Early research indicates，Self -faced recognition will be in various nerves or developmental disorders bet365 Play online games (such as autism、acquired brain injury、Alzheimer's disease, etc.) is damaged。but，Anya and others recently discovered，Autism features are related to the facial view time of the upper half，That is, compared with the faces of recognition as "self"，The autistic characteristics of the faces identified as "others" have stronger negative correlation with the eyes of the eye area。The research of Anya and others did not find the characteristics of the characteristics of autism patients with the uniqueness of the self -uniqueness，This indicates that the features related to autism may be related to self -processing in specific fields。

People have obtained inconsistent results of patients with schizophrenia。2006，Farzin Irani research discovery，Patients will have a specific face to recognize it before recognizing。and Kristin and others found that patients will have the overall face -related face -to -face facial for patients in 2013.，Patients with poor grades of self -faces。2002，Carmel M. Loughland and others' eye movement research discovery，Patient's eye movement scanning path is limited，For example, less gaze、less eyes jump，and avoiding relevant information of the face。2010，Céline Delerue and others studied discovery，Conditions that do not provide any commands than passive，Under the active conditions of the self -faces directly，Patients will notice the characteristics of the self -facial features。2011，Sara A. Beedie and other people studied discovery，Patient's visual search for visual scenes is damaged，This indicates that the low -level visual search of the opposite side will also be damaged，But this requires further exploration。Recent，Bortolon Catherine and others discovered，Patients can recognize their own faces，And focusing on the relevant features of the face in a way similar to healthy people。

bet365 live casino games other，Research found out，Patients with Tang's syndrome have atypical gaze mode in terms of facial recognition，Especially they seem to deliberately avoid watching the emotional face，Cognitive processing of this kind of emotional and psychological information follows a acquired emotional style。

　　Evidence at the nervous level

A large number of research from the nervous level also provides sufficient evidence for the advantages of self -facial recognition。2005，Lucina Q. Uddin et al. Research on the brain area of ​​self -facial recognition，The self -faced activation activates the right side and goes back。2006，Steven M. Platek and others further discovered，Compared with the faces of others who are familiar with different degrees of familiarity with others，The brain area of ​​the self -facial recognition activation is different。

Another，Studies at the nervous level found that self -facial processing is related to some ease and electrical components。2002，Stéphanie Caharel and others found that the N170 volatility was adjusted by self -faces。2010，Helen Keyes and others further discovered，Compared with familiar and unfamiliar faces，The self -facial recognition of the subject has triggered a larger N170 volatility。Therefore，N170 volatility is a specific facial Electrical composition，Structure coding of the face。Some people think，The N170 volatility that appears during self -facial recognition may be caused by some facial stimulation。but but，N170's self -facial effect is not always possible to appear，Puting it as an effective physiological indicator for self -faces needs to be further explored。

At the same time，In the identification task，N250 volatility is another important component related to faces。2006，James W. Tanaka and others discovered，The subject has a larger volatility for the N250 familiar to the face，This Bet365 app download ingredient is also very sensitive to the self -facial face。Compared with unfamiliar faces，Self -faces can cause larger N250 wave amplitude。Another，P200 also began to attract the attention of researchers。Johanna Stahl and others discovered in 2008，Compared with self -ethnic faces，Alien faces have triggered a smaller P200 volatility。2009，Seth n. Greenberg and others discovered，Compared to familiar faces，Test the overall psychological appearance of the subject's face is slower，Fast speed of the characteristics of a certain part of others，For example, nose。This description，Compared with others' faces，Self -faced recognition is more distinctive。2010，Case and others also found that the self -facial recognition is related to P200 volatility，Compared with familiar and unfamiliar faces，The self -facial recognition of the examiner has triggered a smaller P200 volatility。，Different processing methods for self -faces will also lead to different qualitatives of P200 volatility，For example, different overall cognitive processing。Therefore，P200's cognitive significance for explanation of self -facial recognition is a question worth exploring，Because this composition may be an important indicator of self -facial recognition。as an indicator of the face，N170 waves and N250 waves still have some problems in terms of reliability and specific。P200 volatility is more effective for self -facial recognition、Reliable and specific indicators。In the future research，For example, the face familiar to the individual、Alien face、Facial faces of other ages, etc.，This can support P200 volatility as an indicator for self -facial recognition。

other，Research also found，P300 is also an indicator for self -facial recognition advantages effect。1998，Hideaki ninomiya and others discovered，Under passive attention conditions, self -faces are more P300 in the face of self -faces Bet365 lotto review than familiar others。2006，Sui Jie and others discovered，Self -faces in the right forehead cause a larger P300 volatility than others' faces。2010，Pawel Tacikowski and others further discovered，The response time of the subject's face faces is shorter，and caused a larger P300 volatility。At the same time，Research on high -level cognitive activities found，Self -faces will cause a larger P300 volatility。For example，Zhan Youlong and others discovered in the clue mission of the 2016 Money Reward，The perception of self -facial information on the subject has triggered a larger P300 and LPP volatility。2017，Zhan Youlong and others further the ERP Studies Impact on Self -Facial recognition time process of consciousness and unconscious cognitive rewards，Awards value、There is a significant tripartite interaction between the reward type and the type of facial type，Whether it is upper or down the threshold，Self -faces will cause a larger P300 volatility after high rewards。This indicates，Consciously handle the reward and unconsciously handle the reward，By effectively combining the value -related value with self -association，It has obvious advantages in promoting self -facial recognition。

At the same time，2017，Ilona Kotlewska et al.，SSVEP) method，It has been found that there is a significant difference in the nervous level of the past and the current self -facial faces in the past，Now self -faces induces a larger SSVEP volatility。

In short，The speed of searching and recognition as a target stimulation is faster than other faces，in behavior、Eye movement、The processing characteristics of the facial imaging and the composition of the brain and electrical composition。An important indicator of self -consciousness，Self -face recognition advantages are conducive to the development of self -consciousness，Let people better accept their faces，It is also conducive to forming a good personality，Bet365 app download to improve the level of mental health。
