Autism from the inside

Left Hemisphere, Right Hemisphere & The “Mechanics” Of Autism “Fruit Salads”

Autism and Aspergers Hemishpere Image

When looking at autism “fruit salads” and function of both brain hemispheres it is interesting look at the difficulties in each area.

Looking at Donna Williams’ work on the subject of the differences between “Aspie” and “Autie” fruit salads was to do with hemisphere dominance and neglect a trade off between on or the other with “Aspinauts” being the “grey area” of in-between.

On a personal note I always thought she was on to something and looking at this simple table backs it up, consultancy observations, personal experiences and tireless effort to give people a better understanding of both DISablity and disABILITY with autism.

Right Hemishpere (Asperger’s) “Fruit Salad”

Extralinguistic Deficits

Again, RHD patients are unlikely to display the kinds of phonological, syntactic or semantic problems associated with aphasia. However, although they do not typically have many specific language problems, they definitely have difficulty communicating. This impairment seems to follow from an inability to integrate information; RHD patients apparently do not make adequate use of context in their interpretations of linguistic or nonlinguistic messages. They have difficulty distinguishing significant from unimportant information. For example a patient of mine when asked to describe the “Cookie Theft” picture card from the Boston focused on irrelevant features without describing the overall picture. Some aphasics with typical left hemisphere lesions present with executive function disturbance similar to right hemisphere syndrome.

Literal Interpretations

RHD patients may be able to comprehend only the literal meaning of language. Thus, they will often fail to understand many jokes, metaphors, irony, sarcasm, and common sayings that include figurative language. For example, if an RHD patient hears someone say that they are about to “hit the ceiling,” he might assume that the person is really about to begin striking the ceiling. Such a patient may also have trouble understanding indirect requests. For example, if he is asked if he “could open the window,” he may fail to identify this as a polite request and simply answer “yes” rather than opening the window.

These problems with figurative language may be viewed as one manifestation of the inability to base interpretations on context.

Difficulty identifying relevant information

When listening to a conversation or reading, an RHD patient may fail to abstract the main point contained in the information being shared. This happens in spite of the fact that, unlike an aphasic, the patient can understand all the individual words and grammatical structures used. For RHD patients, it appears that their comprehension of everyday language is impaired by a failure to distinguish important information from irrelevant detail and also by an inability to integrate According to Blake 2007, RH patients have difficulty comprehending non-literal language, humor, and multiple interpretations Furthermore, Blake says that their difficulty with language production includes: impulsivity, inefficiency, and egocentricity. She also says that the same problems are seen in traumatic brain injury.

Inability to interpret body language and facial expressions

In a conversation, RHD may miss out on important cues that should tell them about the emotional state and true intention of the person with whom they are interacting. This inability to interpret body language and facial expression may be related to an overall failure to use context in the interpretation of individual pieces of information. Problems with the interpretation of facial expression may also be due to the fact that RHD patients often fail to maintain eye contact with their conversation partners.

Flat affect

RHD patients may fail to display a wide range of facial expressions themselves. Also their speech is frequently aprosodic, or lacking variations in pitch and stress. Some patients will sound “robot-like,” and thus be unable to express emotion or changes in meaning via changes in intonation. These patients will no longer be able to vary pitch to signal the difference between a question and a statement or use word stress changes within a sentence to signal a difference in meaning.

Problems with Conversational Rules

RHD patients may fail to follow conversational rules, including those governing turn-taking, the initiation and closure of a conversation. RHD patients may tend to dominate conversations, as they are frequently verbose. They may also fail to properly estimate levels of shared knowledge, failing to give the listener enough background information to understand their statements. According to Myers and Mackisack (1990), RHD patients appear to not care about the needs of the listener. They, like children in an early developmental phase, may assume too much knowledge on the part of the listener; or not enough. They appear to answer without adequate search for the right answer. They also may fail to pick up on non verbal cues that signal listener’s reactions.

Impulsivity

RHD patients may exhibit poor judgment and problem solving abilities. They may require constant supervision due to a tendency to attempt tasks of which they are no longer physically capable. This may be related to anosognosia. They may also exhibit impulsivity in the sense of failing to censor the statements they make to other people.

Confabulation

RHD patients may make untrue statements. These do not usually seem to be deliberate lies. According to Brownwell et al. (1995), this may be the patient’s way of responding to his own confusion rather than attempts to mislead the listener

There tends to be a lower level of visual-verbal processing difficulties in this profile, social emotional agnosia, alexithymia, issues around a shared “sense” of social, self and other. Internal mentalising (to gain meaning)  would make sense.

Author: Paul Isaacs

Paul was branded as a “naughty & difficult child” at school. He was classically autistic and non-verbal due to speech articulation difficulties. He had complex sensory issues and appeared both deaf and blind. He gained functional speech around the age of 7 or 8 years old. He went through the mainstream school system with no additional help or recognition of his autism. Consequently, he did not achieve his academic or his social potential and had very low self-esteem. At age 11, Paul was referred to the children’s mental health service with childhood depression where he was regarded as “developmentally underage” and having speech problems. As an adult, Paul had a string of unsuccessful jobs, and his mental health suffered. He developed both Borderline and Schizotypal Personality Disorders in early 2007. He was referred to mental health services and misdiagnosed with “Asperger traits with a complex personality”, which did not satisfy Paul or his family. A local autism organisation put Paul in touch with an experienced psychiatrist, who diagnosed him with Autism at 24 years old. In 2012 Paul was also diagnosed with Scotopic Sensitivity Syndrome by an Irlen Consultant who confirmed that he also had face, object and meaning blindness – conditions which Paul describes eloquently in his speeches and training sessions. He also has dyslexia, dyscalculia and also a dissociative disorder. Having started working as an local autism organisation as a public speaker in 2010, Paul joined their mission to promote autism awareness. His hope is that others will not have to suffer as he did. Now also a core member of our Training Team, Paul continues to enhance true understanding of autism at every opportunity. Paul has released and published 5 books on the subject of autism published by Chipmunka publishing and has contributed to other books too. Having overcome many challenges to achieve the success that he now enjoys, Paul’s message is that Autism is a complex mix of ability and disability. He firmly believes that every Autistic person should have the opportunity to reach their potential and be regarded as a valued member of society. Apart from autism related blogs Paul also write about movies, fashion, art and anything that is of interest. As of August 2015 Paul now works as a freelance speaker, training and consultant in and around the Oxfordshire & Buckinghamshire area.
