The Inverted Face Effect: How does it work? “The disorders symptoms are like psychotic behaviours orhallucinations”Human facial recognition ability relies on specialized computations and dedication to brainnetworks. This simple demonstration can be studied through the ‘Inverted face effect’ which isdefined as Recognizing an upside down face is far more difficult to right side up. (ADD AREFERENCE)How does it works?Our perception of concave mask of face appears as a normal convex face. The convex face willappear in a single direction. The inverted face appears to move when the viewer is looking fromstraight. This is all possible due to strong presence of top-down influence in normal (BEFOREEXPLAIN BETTER HOW IT WORKS THEN THE CASE OF STUDY) AS AN EXAMPLE) peoplebut patient of schizophrenia because of the fact that they rely on stimulus driven processing andless conceptual driven processing. (ADD A REFERENCE)Schizophrenia, IS a disease or mental disorder that is debatable. but the fact that it affects aperson’s of what he thinks,of thinking, feelings or behaviours. It is like They have lost touch in realworld and living in some sort of imaginary world. (REFERENCE)This disorder The symptoms of the disorder can be positive, negative and cognitive in nature.Positive symptoms for example are like psychotic behaviours; like hallucination whereas negativebehaviour is associated with normal emotion and behaviour like of reduced feeling and speaking.The cognitive symptoms subtle which can be mild or severe thus our study focused on thecognitive abilities; especially the facial changes that we can notice with a person facing suchmental disorder. For the purpose of study, we took a student who has been previously doubted tobe facing some sort of cognitive disorder and a normal person a healthy individual with no suchsymptoms, has gone through 3 days observation to test in various way(how have they beentested)to arrive at result.
Inverted face effect is basically the loss of normal proficiency at face perception when faces areinverted. Inverted face is not perceived or recognized using the same processes as upright face.Inverted face are harder for normal objects to learn as measured to recognize the performance. Ina study it is found that inversion effect is nil in case of children. According to survey, it is gainfound that right hemisphere which is reported superior to left at recognizing face showedsignificant difference in inversion face effect. THIS SHOULD BE IN THE INTRODUCTION??Day-1 (participant 1)On first day, we found that the person is having problems or alterations in several domains ofvisual processing. This we came to know from the which was eye movement. Here We found thatthe person is not able to concentrate on most of the informative regions like of the eyes. It is foundthat there is lack of efficiency in finding information from inverse face. To find whether inverse facehas any effect on him the participant , we tried even with noise manipulation was used. Here wefound that The participant has an increased internal noise with coordinates with decreasedinformation efficiency resulting impair face discrimination and reduced face inversion effect.Day-2- Experimental strategies For the purpose of study a line drawn schematic has taken been used as the stimuli. It is not theusual photo image rather a face like object containing a minimal clues for identifying facial andemotional expressions. For measuring performance, we took a tree (a non-face object as stimuli.Like line drawn face, Line drawn tress are made with same number of line alignment. The first test –
