Theory of Mind (Adult Conceptions)
ADULTSThoughts are different than things
Beliefs are different from actuality
Desires are different from outcomes
Fantasy is unconstrained by factuality
Mind is private and individual
False Belief Tasks: Stories often depend on them
Multiple layers of mental processing representation
My wife knew I didn’t take out the trash last night, and I knew she knew this, but I didn’t know she knew that I knew she knew…
#5 Seeing leads to knowing The role of eyes in cognition, emotional expression, social communication
#9 Eyes reveal intentions, thoughts
#19 Decode complex mental states from eye region
#10 Monitor own intentions
#8 Social JudgmentsJudge social normalcy of each [ ]
The market where Tommy always shopped had a small sign on the door that read “Bare Feet Prohibited in this Shop by Law”. One summer day Tommy saw a girl his age enter the store without shoes. Tommy wanted to warn her about the sign but he was too shy to speak up. So he pushed his cart close behind hers down aisle after aisle [ abnormal; HFA normal].
Once or twice the girl looked back at him with a cross expression. Suddenly she wheeled into the express checkout with 12 items in her basket although the sign said “FOR 10 OR FEWER ITEMS [ normal; HFA abnormal].
Tommy was more upset than ever. This girl was tempting fate, but he relaxed when the checkout person let the girl through. Just then the barefoot girl turned back and said to him “Buzz off or I’ll call the cops [normal; HFA abnormal ]
HFA= high functioning autistic
Theory of Mind tests1. Mental-physical distinction (e.g. thinking vs holding dog) 2. Function of the mind3. Reality-appearance distinction (Apple-shaped candle)4. False belief tasks (1st order) (What might she be thinking?)5. Seeing leads to knowing6. Recognizing mental-state words; spontaneous use7. Spontaneous pretend play8. Understanding complex causes of emotion (stories)9. Eyes reveal intentions, thoughts10. Monitor own intentions11. Deception12. Understanding metaphor, sarcasm, irony13. Pragmatics in speech, violations14. Sensitivities to listener’s mental state (faux pas test)15. Imagination (draw unreal object like 2-headed platypus)16. Real life social skills17. 2nd-order FB tests (mental states about others’ mental states >6y)18. Understanding complex mental stories (e.g., double bluff)19. Decoding complex mental states from eye region
AQ – Autism Quotient (modified) for high
functioning autistics1. I find it hard to make new friends. 2. I do not usually enjoy social occasions
3 I prefer to do things the same way over and over again. 4. I find it difficult to do more than one thing at once.
5. I often notice small sounds when others do not.6. I usually concentrate more on the small details than the whole picture. 7. I like to collect information about categories of things (e.g., types of cars, birds, trains, plants). 8. I find it very easy to play games with children that involve pretending.
9. I find it easy to 'read between the lines' when someone is talking to me. 10. When I talk on the phone, I'm not sure when it's my turn to speak.

AUTISMa neurodevelopmental disorder that impacts cognition and behavior
Schizophrenia also a neurodevelopmental disorder
In 1943 Leo Kanner studied 11 children in USA with “early infantile autism”. In 1940s Hans Asperger in Austria studied 400 children with “autistic psychopathy.” “Auto” –child is locked within him/herselfConsidered an emotional disturbance for first 30-40 years of study
WHAT IS AUTISM?Abnormal brain development affecting social interaction and communication skills.
Difficult to communicate with others and relate to the outside world.
Hans Asperger (1906-1980)
Pediatrician described group of boys with:
poor social interactions failures in communication narrow interests
“a personality disorder”His work, translated into English in 1981, challenged view of autism as silent, aloof child caused by lack of mothering
Led to Autistic Spectrum model
“ The nature of these children is revealed most clearly in their behavior towards other people. Indeed, their behavior in the social group is the clearest sign of their disorder and the source of conflicts from earliest childhood.”
WHAT IS AUTISM SPECTRUM?
Broad group of pervasive developmental disordersTypically appears first 3 years of life
Unusual responses to peopleAttachment to objectsResistance to change in routineSensory sensitivitiesRepeated body movements (hand flapping, rocking).
Pervasive Developmental Disorders
Autism
Disorder
Asperger’s
Syndrome
PDD-NOS Rett’s DisintegrativeDisorder
1. Autistic DisorderImpairments in 1. social interaction2. communication, and 3. motor function
Apparent before age 3.Restricted interests and activities
2. Asperger’s DisorderImpairments in 1. social interaction2. no significant general delay in language
Sometimes hyperverbal
3. motor function
Restricted interestsDiagnosed at 7 to 9 years of age or older
3. Pervasive Developmental Disorder – Not Otherwise Specified
(PDD-NOS)
Often referred to as atypical autismUsed when child does not meet specific diagnostic criteria, but show severe and pervasive impairment in social behavior, nonverbal communication
Causes of autismAbnormalities in brain development/neurochemistry, with genetic factorsNot Bettleheim’s psychogenesis
Autism PrevalencePredominantly in boys
(80%, 90% Aspergers)Hypermale modelSystems vs Empathy
1 in 200 births,with 1/16 repeated chance
Runs in families (and with schizophrenia)
1. Communication disturbances
Broad range of abilities, from no verbal communication to hyper-verbal
About half will never develop useful language
A. Delayed languagePronoun reversal: “You want a popsicle.”Difficulty in shifting topics
B. EcholaliaC. Pragmatic shortcomings
No knack for the “conversational arts”.Lack of reciprocity --talks ‘at you’ Inappropriate topics (e.g., train schedules)
2. Impaired Social Interactions
Impaired use of nonverbal behavior such as poor eye contact
Lack of peer relationshipsLack of joint attention
spontaneously share enjoyment with others
Lack of reciprocityTheory of mind deficits
3. Behaviors
Repetitive behaviorsobsessions, tics, perseverationsself-stims like hand flapping and rockinginflexible adherence to nonfunctional routines or rituals
May insist on particular furniture arrangement, food at meals, TV showsNeed for symmetry
4. Intellectual functioningAutism occurs in children of all levels of intelligence, from gifted to mentally impairedOriginally judged as mental retarded
75% below 70 IQ in previous decades
Verbal and reasoning skills difficultWeak central coherence
Savant syndrome
Savant Syndrome (previously Idiot Savant)
1 in 10 autistics exhibit savant skills

Autism & Science Hans Asperger (1979)
“It seems that for success in science or art, a dash of autism is essential. For success, the necessary ingredient may be an ability to turn away from the everyday world, from the simply practical, an ability to re-think a subject with originality so as to create in new untrodden ways, with all abilities (channeled) into the one’s speciality.” (1979).
