uncanny valley

how are we hypersensitive to faces

-aware of very subtle changes -we see faces everywhere -ex. cars -we can subliminally "recognize" faces shown for 1/50

what do subliminal faces shown to us have an effect on

-emotion -opinion (chinese character) -your face as well (smiles)

we can subliminally "recognize" faces shown for 1/50

-famous vs. infamous

what can a face communicate to us

-identity -intent -fitness -language (lipreading) -facial expression

Facial Inversion Effect

-inversion inhibits face recognition disproportionately

do we judge personalities from faces

-our impressions are formed at 1/10 sec -self fulfilling prophecy -expressive habits throughout our life show on our faces (happy and frowning wrinkles) in elderly faces

prosopagnosia

-say they cant know someone they know but have a subliminal reaction to dictate they subliminally "recognize" faces -just not aware they can recognize them -inability to recognize faces after stroke or something

cultural universality in facial expressions?

-so a smile is a smile everywhere but the degree is different -display rules -strength of emotion ans expression -positive vs. negative: interpretation of faces are diffrent but they catagorize them as positive or negative more universally

reserch in recognizing faces by the way they move

-using white dots on faces to detremin the movement -we would be able to recognize friends by how they move their face

Development of face perception

9 minutes old -face patterns preferred 36 hours -expression imitation 1-3 months -parent recognition -predisposition for faces Faces have profound adaptive significance

Film:the curious case of benjamin button -might have solved the uncanny valley by animating brad pitts character aging so well people didn't know it was animated

what do faces precieve

From a face, you can rapidly determine an individual's identity, gender, emotional state, intentions, genetic health, reproductive potential, and even linguistic message (through lip-reading). move. And facial motion can also convey information about the age, gender, expression, and even attractiveness of an unfamiliar face.

All or none principle of uncanny valley

Once something looked good all of a sudden something else started to look face in animating a face -ex. eye moisture

why do covertly do facial expressions

Research shows that if your covert reactions are inhibited by either high-tech means (transcranial magnetic stimulation) or low-tech means (firmly biting down on a stick), your ability to recognize expressions would be changed. -used to recognize expression -use it to emaphize somone elses emotion - interact with your own emotions. For example, covert reactions are influenced by emotional context.

why do we feel disgusting to things in the uncanny valley

appearance of natural but not alive makes us wanna avoid corpses

why does looking at a face upside down harder

configural information (how fae each part of face is) is no longer available: the eyes are now below the nose which is below the mouth.

we subtly inadvertently imitate facial expressions when looking at a face

if a face is smiling in a picture they find subtle changes in the person whose looking at it -"smiles are contagious" -muscle, visible changes -subliminally induced -influences emotion - not trusted research

preventing facial extressions does what

influences emotion and lowers you well being

Uncanny Valley

is a common unsettling feeling people experience when androids (humanoid robots) and audio/visual simulations closely resemble humans in many respects but are not quite convincingly realistic. -specific to human forms -we are super sensitive to human faces because we are expert face percievers

what doesnt activate when watching a humaniod rather than a human doing something

mirror systems activate when watching a person but not a robot -Similarly, mirror neuron sites engage when you watch an animation of a near-human figure walking, but not a stick figure walking. It seems that a degree of human realism is important for your brain to internally mirror the actions of others.

why are we expert face precievers

nothing communicates as efficiently as the human face -hypersensitivity to faces

we unconsciously recognize facial expressions

rate Chinese characters but then flash positive or negative things subliminaly influences aesthetic judgments, hypothetical decisions, mood to when rating the chinese characters

why are we right at judging personalities by looking at a face

self fulfilling prophecy: we might grow into our faces so if we look mean ppl are going to treat us that way

what do we do to recognize a face

to recognize a face, you not only look at its features, but you also look at how those features are configured relative to each other.
