Question Answer
What are the difficulties in face processing regarding Williams Syndrome? Integrating multiple features, abnormal processing. Williams Syndrome do not use right hemisphere to process faces like typical people do
What are the language features of someone with Williams Syndrome? Seem normal, but delayed in acquiring some aspects of language, seem to use more semantic information, less morphological information.
In Williams Syndrome what is found regarding sound? EEG response to auditory stimuli seems to be hypersensitive, parents report sensitivity to sound
What is the problem with neuroanatomy research with Williams Syndrome? All adult children, not relevant since behaviour develops in the developing brain. Doesn't tell us how it develops differently
Generally what is seen in adults with Williams Syndrome? Smaller volume of brain overall, and grey matter, particularly cerebrum. Neurons are also abnormally arranged
What do syndromes having distinct facial tells us as a whole? That we need to look at all aspects of a person, not just the brain
What do strong modularity theories imply? Some functions are impaired and others are unimpaired, over imparied vs less impaired. Also consistent in infancy.
Who said development itself is key to understanding developmental disorders? Karmiloff-Smith
What are the problem behavioural characteristics of someone with Fragile X? Poor performance IQ compared to verbal IQ. Weakness in attention, verbal short term memory, planning and verbal fluency. Act similar to child with ADHD.
What is executive function? a set of cognitive abilities that control and regulate other abilities and behaviors
Do Fragile X have a problem with or enhanced executive functioning? Problem (attention, planning, etc)
What abilities are enhanced in Fragile X Facial recognition, visual short term memory, syntax
Do patients with Fragile X have distinctive facial features? Yes
What does drinking a lot of alcohol (binge or chronic alcoholics) during pregnancy cause a baby to have? Foetal alcohol syndrome
What do distinctive facial features arise from in foetal alcohol syndrome? Prenatal problems, slow growth and small head.
Despite from psychological problems, what general problems do those with foetal alcohol syndrome have? Health problems
What are neural characteristics of someone with foetal alcohol syndrome? Impaired executive function, particularly in attention
What are behavioural characteristics of someone with foetal alcohol syndrome? Development delay, frontal lobe syndrome, including behavioural problems; aggression other social difficulties
How common is Williams syndrome? Not common
Does William Syndrome have distinctive facial features? Yes
What are the three factors of modularity? Implications, arguments and dissociation
Does autism have distinctive facial features? No
What is the triad deficits in autism? Social interaction, social communication, imaginative behaviour
How do people Autism with look at social interaction? Simply have no desire to interact with others, those with higher functioning learn to interact and go along with it
What causes have been identified for autism? Some genetic markers, but not all involved, nothing concrete.
What was previously thought to cause Autism, and why has it been thrown out? Not stimulating enough environment, but it has been disredited
What is Sigmon's theory of autism? Lack theory of mind, mind blindness. Have specific social difficulties, could be the basis of the lack of theory of mind.
What do autistic people have a problem with and a benefit in? Executive function, and benefit in central coherence tasks
What is key about the disabilities in Ausitics? They vary
Who found monozygotic twins have a higher incidence rate of both having autism, than diozygotic? Ronald et al.
What has found to be responsible for social difficulties and non-social difficulties? Genetics, different for each
What are the results of Sally-Anne task with autistic? Most have non-mentalising errors, but some don't have problems with it
What are neural characteristics of someone with autism? Poor/reversed lateralisation, cerebullum affected, brain stem/cranial nerves
What could cause the poor/reversed lateralisation of ausitic people? Language developing at an atypical rate
Thalidomide victims have higher risk of developing? Autism, cerebullum, brain stem and cranial nerve link
In autism what causes distinctive facial features? Other causes, ie other disorders
How is Williams syndrome seen to be a dissociation to austism? Very sociable and appear to have good language, but deficits in visuo-spatial processing and non-verbal processing.
In Williams syndrome, what is facial processing like? It seems normal but it is different
What is the genetic Williams syndrome? Deletion on long arm of chromosome 7.
Regarding Williams Syndrome, there are claims of specific genetic deficits lead to, what? And what is the problems with these claims? Specific phenotype features. Individuals can have only some of genes missing, and do not necessarily have correct deficits
Which disorders have a clear genetic cause? Downs syndrome, Williams syndrome, fragile X syndrome
What is the most common genetic disorder, and is it heritable? Downs syndrome, and it is not hertiable
Why does downs syndrome have the highest survival rate? Gene which is copied is not important
What does down syndrome lead to an increased risk of? Alizmers, heart problems, shorter life span
What are the distinctive features of someone with Down's Syndrome? Facial features, tongue out due to tongue being weak and smaller mouth cavity
What are the neural characteristics of someone with downs syndrome? Smaller temporal lobe (reflected in auditory problems) and bigger posterior areas (reflected in better visual)
What originally did down syndrome used to be seen as a learning disability? How has it changed? Originally thought to be a general learning disability, but has proven not to be true due to having some enhanced abilities
What is the abilities of someone with down syndrome like? Better visuo-spatial, but auditory, particularly short term auditory memory, is poor. Also have motor problems, reflected in speech
What are patients with downs syndrome have a higher risk of due to not having a social advantage? Autism
What is the second most common genetic disorder, and is it heritable? Fragile X and it is heritable.
What causes Fragile X? When there is a break in the X chromosome
Which gender is more likely to suffer from Fragile X and why? Boys, as they have two X chromosomes
Which gene is impaired in Fragile X, and what is it responsible for? How is it seen in the patient's brain? FMRP gene, responsible for the growth of dendrites. Shown in different growth of brain.
