Reading Difficulties and ASD

transcript

Patricia Rakovic

• Based on the notion of a “ culture of autism”( Mesibov et al. 2005) the way individuals with ASD think and behave should not be seen as deficits. Rather, literacy experiences should build on each individual’s strengths and interests

• Reading instruction therefor requires differentiated instruction and support

Be discerning & selective when reading comprehension

The Fit with ASD

View thru the

ASD lens

Autism, Cognition and Reading Comprehension

• Literacy skills provide the foundation for improving quality of life for all regardless of ability of functioning level.

• Skilled readers do the following– Access relevant background knowledge– Make inferences– Monitor reading comprehension– Demonstrate fluency– Understand structure and vocabulary of text– Integrate relevant information from their own

world to make meaning

Autism, Cognition and Reading Comprehension

• It is important to have an understanding of the autism to be able to provide quality literacy instruction

• Individuals with ASD my be able to fluently decode because of their strength of word calling and decoding but struggle with comprehension.

• Characteristics of ASD include differences in – Socialization– Communication– Restricted interests and behaviors

Characteristics that impact Reading

• Three models of constructs provide insight into the nature of ASD: –Theory of Mind–Executive Function –Central Coherence

Theory of Mind

• First introduced by Baron-Cohen, Leslie and Frith refers to two important abilities– The capacity to recognize the thoughts,

beliefs, and intentions of others and understand that these mental states are different than our own.

– Using this understanding to predict the behavior of others.

Theory of Mind

• Challenges with perspective taking impacts reading or listening comprehension as one needs to understand how and why a character behaves in a certain way

• Literal interpretation of language, intense interest in certain topics and challenges in engaging in shared experiences impact literacy development.

• Will have difficulty making predictions and inferences

Executive Function• Executive function processes are critical for planning

and carrying out goal-directed behavior while tuning out unnecessary distractions or information. Some of these processes include planning and initiation, working memory, inhibition, cognitive flexibility and fluency.

• Some individuals have difficulty inhibiting responses or managing impulses

• Research suggests that while individuals with ASD are able to access background knowledge, applying the background knowledge across text can be challenging.

Executive Function• Monitoring and self-correcting is critical for

accurate understanding; difference in attention, memory, organizing and planning may make monitoring and self-correction challenging for individuals with ASD

• These differences impact literacy experiences

Central Coherence• Neuro-typicals tend to focus on meaning or the big

picture• Individuals with ASD focus on the specific details• Weak central coherence impacts literacy

development related to making meaning from text, as selecting important details to create a larger picture becomes critical to comprehension

• The ability to identify relationships between words, concepts and/or experiences leads to missed connections

• As the complexity of text increases the ability of individuals with ASD to integrate information for meaningful purposes may be challenged.

Language Comprehension• Differences exist in how individuals with ASD

construct meaning from text. These differences include:– Acquiring certain vocabulary forms before

others ( i.e, nouns before verbs)– Difficulty using bound morphemes( play versus

played)– Challenges with pronouns

Examining the Reading Process: What is Reading?

Defining Reading

• Our definitions of reading guide our understanding and views

• Different reading assessments are based on different definitions of things like “comprehension”

The Simple View of Reading R = D x C

Reading is the product of the processes(x not +). It involves language and cognition.It is not as simple as it sounds, because the

processes of decoding and understanding are complex and inter-related

If you can Decode and have Linguistic Comprehension, you are reading!

Gough & Tunmer, 1986

The Simple View of Reading R = D x C

Problems can arise with D, C or both →Problems with “D only” can be called dyslexia

Problems with “C only” can be called hyperlexia

(different than precocious hyperlexia)

HYPERLEXIA

“Strong mechanical word recognition with comparatively poor comprehension”

GOOD DECODING with POOR

COMPREHENSIONIN PEOPLE WITH ASD

A more complex definition of reading National Reading Panel (2005), p.28

“A form of dynamic thinking [that] includes • interpreting information through the filter of one’s

own knowledge and beliefs, • using the author’s organizational plan to think about

information (or imposing one’s own organization on ideas),

• inferring what the author does not tell explicitly, as well as many other cognitive actions.”

What is comprehension?

The purpose and the essence of reading

Effective Literacy Instruction

• Research has indicated that engaged behavior is the single best predictor of academic gains for students with disabilities

• Students with ASD demonstrate differences in executive functioning that make engagement in the classroom challenging

Comprehension=Constructing Meaning

1. Understand the text at the word and sentence level, “word knowledge”

2. Identify relevant information

3. Relate, compare and integrate to what is already known a.k.a. “world knowledge” or prior knowledge

4. Internalize to own experience

5. Create a new construct or idea, the gist or meaning

6. Store the new idea7. Retrieve upon demand

Factors contributing to reading comprehension

• Fluent word recognition skills• Vocabulary knowledge• World knowledge• Comprehension monitoring• Active use of comprehension strategies

Pressley, M. (2001). Comprehension Instruction: What Makes Sense Now, What Might Make Sense Soon

http://www.readingonline.org/articles/handbook/pressley/

What good comprehenders do

• Know why they are reading• Understand the point• Relate to prior knowledge• Relate to other text• See cause and effect• Interpret characters’ actions and emotions• Understand the author’s intentions

What good comprehenders do• Monitor understanding• Use strategies flexibly and in

combination– Re-read– Look back

• Predict• Revise/repair• Infer• Summarize• Mark, highlight

5 types of reading comprehensionAll five types of reading comprehension may be challenges for readers with ASD who can decode but don’t understand

1. Literal2. Inferential3. Critical4. Affective5. Lexical

(Adapted from Salvia & Ysseldyke, 2004. Assessment in inclusive and special education, ninth edition. Boston: Houghton Mifflin.)

1. Literal comprehension

Understanding explicit material in text

2. Inferential comprehension

Understanding ideas beyond the literal text by interpreting, synthesizing and extending meaning

3. Critical comprehension

Meaning derived by evaluating, analyzing, and making judgments about material that was read.

4. Affective comprehension

Relating to the material at a personal and emotional level.

5. Lexical comprehension

Making sense of text by knowing the meaning of key vocabulary words.

CommunicationThe language-literacy link

• Understanding oral language• Language processing• Auditory processing

Difficulties with speaking, listening and understanding affect literacy:

reading and writing

The language-literacy link

• A different timeline/uneven development• Receptive and Expressive Vocabulary

(number of words) • Vocabulary Gap• Literal and concrete vs. figurative, abstract and

inferred• Difficulty with images, imagination & imagery

Communication Affects Comprehension• Good readers ask questions before, during and after

reading.• Generating questions before reading helps establish

purpose and focus.• Questioning text while reading helps integrate the

material with background knowledge.• Questioning while reading is a way to monitor

comprehension.• After reading, good readers ask questions about the

meaning of what they read and how to apply the information to their own lives.

Shades of Meaning Activity

• Teaches synonyms, expands vocabulary• Reveals the hidden meaning behind words• Teaches connotation: the emotion and

intention attached to specific words• Clarifies the perspective and intention of

characters or the author (social thinking)

Shades of Meaning RATE (+ – or =) & RANK (light to heavy)

– SLENDER– ANOREXIC– THIN– SKINNY

– PLUMP– CURVY– OBESE– PLUS-SIZED

– UGLY– UNATTRACTIVE– UNSIGHTLY– PLAIN

– INTELLECTUAL– SHREWD– CLEVER– ASTUTE

Effective Literacy InstructionWell implemented instructional strategies can build upon identified strengths. These include:– Visual spatial processing– Keen awareness of visual and/or cognitive

detail– Rote memory– Attachment to routine

Comprehension Activity: Social Thinking and Theory of Mind

1. In random order, write down two things about yourself that are true, AND one “believable lie” on an index card.

2. A volunteer will read to the class3. Try to guess which statement is not true. Talk

about it! 4. .Relationship to comprehension

R &R affects CPoverty of Experience

is not experienced only by the poor

• Perseveration: The knowledge and experience base in ASD are narrow and deep instead of shallow and wide

• Limited background knowledge and exposure to a wide range of topics…and the language that goes with it.

• Affects vocabulary, word knowledge, world knowledge and conversation

• Disinterest in stories about non-preferred topics, less motivation, less reading:

Effective Literacy InstructionSix categories of instructional strategies with strong evidenced based are:• Organized classroom environment• Visual supports• Structured instruction• Curricular modifications• Embedded supports• Maintenance and generalization planning

Effective Literacy InstructionTwo steps to assist in clarifying expectations and reducing competing information are • Segment the space– Clear boundaries to specify the different areas

of the classroom – Only relevant materials in each segmented

space• Minimize auditory and visual distractions

Effective Literacy InstructionVisual Supports• Provide information that is accessible and stable

over time• Reduces anxiety and difficulty around transitions

since students are able to ‘see’ upcoming events and activities

• One type of these is the schedule, there should be two ( classroom and individual)– Individual is for those that benefit from

additional concrete information

Effective Literacy InstructionVisual Supports: Work SystemsWork Systems visually answer four questions• What task or activity is the student to engage in ?• How much work is required OR how long will it take ?• How will the student know that progress is being made or

the activity is finished?• What happens next, after the work or activity is finished

Effective Literacy InstructionABA strategies that are helpful in literacy instruction• Task analysis• Prompting• Reinforcement• Chaining

Task Analysis

• This involves breaking down complex behavior into its component parts.

• Skills can be broken into many steps and taught in a number of phases

Prompt• In ABA framework a prompt or a cue ( stimulus)

is provided to the student; the child responds, and a consequence follows

• Least to most prompts is a prompting strategy that can be used in effective literacy instruction. Least to most prompts may follow this hierarchy:– Gestural– Visual– Verbal– Model– Physical

Reinforcement

• Reinforcement is used to increase the use of a target skill or behavior. It is the contingent presentation of a reinforcer immediately following a student’s use of the skill

• To effectively use positive reinforcement, teachers must first establish a target skill and performance criteria

• The steps in a task analysis form a behavioral chain that can be taught. The process of reinforcing responses that occur in a sequence to form complex behavior is called chaining

Contexts for Building Emergent Literacy Skills

• Shared Book Reading– Style of book reading in which the adult and child have rich

conversations about the content and pictures in the text• Interactive or dialogic book reading

• Dramatic Storytelling and Retelling– Activity in which children invent and act out stories or retell

stories heard or read• Interactive Routines– Predictable, repeated actions written down as a schedule

or chart

Contexts for Building Emergent Literacy Skills

• Music and movement– Enlarged print versions of lyrics written as interactive

charts• Language Experience activities

– Activity in which the teacher guides a discussion and written record of shared experience

• Signing-in and signing-up– Activity in which children write their name on a piece of

paper when they come to school in the morning or for turn taking purposes

• Games– Type of play for targeting emergent literacy skills
