Chapter 9 Notes

Intellectual and Developmental Disabilities

1. Identify the major components of the American Association on Intellectual and Developmental Disabilities (AAIDD) definition and classification system for people with intellectual and developmental disabilities.

· There are significant limitations in intellectual abilities

· There are significant limitations in adaptive behavior as ex-pressed in conceptual, social, and practical adaptive skills.

· Disability originates before the age of 18.

· The severity of the condition is tempered by the individual’s participation, interactions, and social roles within the com-munity; by her or his overall physical and mental health; and by the environmental context.

· Classification for severity of the condition may be described in terms of mild, moderate, severe, or profound intellectual disabilities.

· Educability expectations as a classification are designated for groups of children who are educable and children who are trainable.

· Medical descriptors classify intellectual disabilities on the basis of the origin of the condition (e.g., infection, intoxication, trauma, chromosomal abnormality).

· Classification based on the type and extent of support needed categorizes people with intellectual disabilities as having intermittent, limited, extensive, or pervasive needs for support to function in natural settings,

2. What is the prevalence of intellectual disabilities?

· The prevalence of intellectual disabilities world-wide and across all ages is estimated at 1 percent of the total population.

· There are approximately 600,000 students between the ages of 6 and 21 labeled as having intellectual disabilities and receiving service under IDEA. Approximately 10 percent of all students with disabilities between the ages of 6 and 21 have intellectual disabilities.

· Overall, students with intellectual disabilities constitute about 0.88 percent of the total school population.

3. Identify intellectual, self-regulation, and adaptive skills characteristics of individuals with intellectual disabilities

· Intellectual characteristics may include learning and memory deficiencies, difficulties in establishing learning sets, and inefficient rehearsal strategies

Intellectual and Developmental Disabilities

· Self-regulation characteristics include difficulty in mediating or regulating behavior.

· Adaptive skills characteristics may include difficulties in coping with the demands of the environment, developing inter-personal relationships, developing language skills, and taking care of personal needs.

4. Identify the academic, motivational, speech and language, and physical characteristics of children with intellectual disabilities.

· Students with intellectual disabilities exhibit significant deficits in the areas of reading and mathematics.

· Students with mild intellectual disabilities have poor reading mechanics and comprehension, compared to their same-age peers.

· Students with intellectual disabilities may be able to learn basic computations but be unable to apply concepts appropriately in a problem-solving situation.

· Motivational difficulties may reflect learned helplessness—“No matter what I do or how hard I try, I will not succeed.”

· The most common speech difficulties involve articulation problems, voice problems, and stuttering.

· Language differences are generally associated with delays in language development rather than with the bizarre use of language

· Physical differences generally are not evident for individuals with mild intellectual disabilities because these intellectual disabilities are usually not associated with genetic factors

· The more severe the intellectual disabilities, the greater the probability of genetic causation and of compounding physiological problems.

5. Identify the causes of intellectual disabilities.

· Intellectual disabilities are the result of multiple causes, some known, and many unknown. The cause of intellectual disabilities is generally not known for individuals with mild intellectual disabilities.

· Causes associated with moderate to profound intellectual dis-abilities include sociocultural influences, biomedical factors, behavioral factors, and unknown prenatal influences.

6. Why are early intervention services for children with intellectual disabilities so important?

· Early intervention services are needed to provide a stimulating environment for children to enhance growth and development.

· Early intervention programs focus on the development of communication skills, social interaction, and readiness for formal instruction.

7. Identify five skill areas that should be addressed in programs for elementary-age children with intellectual disabilities

· Motor development skills

· Self-help skills

· Social skills

· Communication skills

· Academic skills

8. Identify four educational goals for adolescents with intellectual disabilities.

· To increase the individual’s personal independence

· To enhance opportunities for participation in the local community

· To prepare for employment

· To facilitate a successful transition to the adult years

9. Why is the inclusion of students with intellectual disabilities in general education settings important to an appropriate educational experience?

· Regardless of the severity of their condition, students with intellectual disabilities benefit from placement in general education environments where opportunities for inclusion with nondisabled peers are systematically planned and implemented.

Communication Disorders

1. Identify four ways in which speech, language, and communication are interrelated.

· Both speech and language form part, but not all, of communication.

· Some components of communication involve language but not speech.

· Some speech does not involve language.

· The development of communication—language and speech—overlap to some degree

2. Explain how language delay and language disorder differ

· In language delay, the sequence of development is intact, but the rate is interrupted.

· In language disorder, the sequence of development is interrupted.

3. Identify three factors that are thought to cause language disorders.

· Defective or deficient sensory systems.

· Neurological damage occurring through physical trauma or accident

· Deficient or disrupted learning opportunities during language development

4. Describe how treatment approaches for language disorders generally differ for children and for adults.
