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 asRecognizingan 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 ofschizophreniabecause 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.butthe fact that it affects aperson’sof what he thinks,of thinking, feelings or behaviours.It is likeThey have lost touch in realworld and living in some sort of imaginary world.(REFERENCE)This disorderThe symptoms of the disorder can be positive, negative and cognitive in nature.Positive symptoms for example are likepsychotic behaviours; likehallucination whereas negativebehaviour is associated with normal emotion and behaviourlikeof reduced feeling and speaking.The cognitive symptomssubtle whichcan be mild or severe thus our study focused on thecognitive abilities;especiallythe facial changes that we can notice with a person facing suchmental disorder. For thepurpose of study, we took a student who has been previously doubted tobe facing some sort of cognitive disorder and anormal persona 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 isbasicallythe 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 thewhich was eye movement.HereWe found thatthe person is not able to concentrate on most of the informative regionslikeof the eyes. It is foundthat there is lack of efficiency in finding information from inverse face. To find whether inverse facehas any effect onhimthe participant ,we tried even withnoise manipulation was used.Here wefound thatThe participant has an increased internal noise with coordinates with decreasedinformation efficiency resulting impair face discrimination and reduced face inversion effect.Day-2- Experimental strategiesFor the purpose of study a line drawn schematic hastakenbeen used as the stimuli. It is not theusual photo image rather a face like object containingaminimal 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 –
