Identify the AAIDD and the DSM criteria for intellectual disability and describe how the two approaches differ. Answer: The American Association on Intellectual and Developmental Disabilities (AAIDD) and the Diagnostic and Statistical Manual of Mental Disorders (DSM) provide criteria for diagnosing intellectual disability (ID), but they differ in their approach. AAIDD Criteria: 1. Intellectual Functioning (IQ): Significantly below average intellectual functioning, typically indicated by an IQ of approximately 70 or below. 2. Adaptive Behavior: Significant limitations in adaptive behavior, which includes conceptual, social, and practical skills necessary for everyday life. 3. Onset Before Adulthood: The limitations in intellectual functioning and adaptive behavior must be present before the age of 18. DSM Criteria (DSM-5): 1. Deficits in Intellectual Functioning: IQ score approximately two standard deviations below the mean (usually around 70 or below). 2. Deficits in Adaptive Functioning: Significant limitations in adaptive behavior in at least one of the following areas: conceptual, social, or practical. 3. Onset During the Developmental Period: The intellectual and adaptive deficits must have onset during the developmental period, which is defined as before the age of 18. Differences: 1. IQ Cutoff: The AAIDD does not specify a strict IQ cutoff, while the DSM-5 uses an IQ of approximately 70 as a guideline. 2. Adaptive Behavior: The AAIDD emphasizes adaptive behavior and its limitations, while the DSM-5 includes adaptive functioning as part of the diagnostic criteria but focuses more on intellectual deficits. 3. Approach: The AAIDD approach is more comprehensive, considering intellectual functioning, adaptive behavior, and age of onset, while the DSM-5 approach is more structured and diagnostic-oriented, focusing on specific criteria for diagnosis. In summary, while both the AAIDD and DSM criteria consider intellectual functioning, adaptive behavior, and onset before adulthood, they differ in their specific guidelines and emphasis, with the AAIDD taking a broader and more holistic approach to diagnosing intellectual disability. 94. Describe the stability over time of intelligence test scores of both the general population and those with intellectual disability. Answer: General Population: Intelligence test scores of the general population tend to be relatively stable over time, especially after childhood. Studies have shown that IQ scores remain fairly consistent from childhood to adulthood, with correlations between childhood and adult IQ scores typically ranging from 0.65 to 0.85. However, there can be some variability, and factors such as education, health, and life experiences can influence IQ scores over time. Intellectual Disability (ID): In individuals with intellectual disability, the stability of intelligence test scores can vary more widely. While some individuals with ID may show stable IQ scores over time, others may experience fluctuations. Factors such as the severity of ID, the presence of other developmental disabilities or mental health conditions, and the availability of supportive interventions and environments can all impact the stability of IQ scores in individuals with ID. 95. Describe the Flynn effect. How do we control for this effect? Answer: The Flynn effect refers to the observed phenomenon of increases in intelligence test scores over time, across generations. This means that individuals in later generations tend to score higher on IQ tests than those in earlier generations, even when the tests are the same. The effect is named after psychologist James Flynn, who extensively researched and popularized this phenomenon. Several explanations have been proposed for the Flynn effect, including improvements in education, nutrition, health care, and living conditions, as well as increased access to information and technology. These factors are believed to contribute to cognitive stimulation and the development of cognitive skills, leading to higher IQ scores over time. To control for the Flynn effect in research, researchers often use "renorming" or "restandardizing" procedures. This involves periodically updating the norms or standards used to score IQ tests to account for the increase in scores over time. By doing this, researchers can ensure that IQ scores are interpreted relative to the performance of individuals in the same time period, rather than compared to individuals from earlier generations. 96. What domains are evaluated for adaptive functioning? How are intelligence and adaptive functioning related? Answer: Adaptive functioning refers to the collection of conceptual, social, and practical skills that individuals need to effectively function in everyday life. These skills are typically divided into several domains, which may include: 1. Conceptual Skills: This domain includes skills related to language and literacy, money, time, and number concepts, as well as the ability to solve practical problems. 2. Social Skills: Social skills involve the ability to interact and communicate with others, form relationships, and understand social cues and norms. 3. Practical Skills: Practical skills encompass activities of daily living, such as personal care (e.g., dressing, bathing), home living (e.g., cooking, cleaning), health and safety, and use of transportation. Assessment of adaptive functioning involves evaluating an individual's abilities in these domains to determine their level of independence and need for support in daily life. Intelligence and adaptive functioning are related but distinct constructs. Intelligence, as measured by IQ tests, reflects cognitive abilities such as reasoning, problem-solving, and abstract thinking. Adaptive functioning, on the other hand, reflects how well an individual can apply their cognitive abilities to everyday tasks and situations. While there is a correlation between intelligence and adaptive functioning, they are not synonymous. It is possible for an individual to have intellectual deficits (e.g., low IQ) but still demonstrate adequate adaptive functioning, especially with appropriate support and accommodations. Conversely, some individuals may have average or above-average intelligence but struggle with adaptive skills, such as those with certain autism spectrum disorders or specific learning disabilities. Overall, intelligence and adaptive functioning are interrelated aspects of an individual's overall functioning, with each contributing to their ability to navigate and succeed in the world. 97. Pick a level of functioning (mild, moderate, severe, or profound) and describe the functioning common to that level. Answer: Moderate Intellectual Disability: Intellectual Functioning: Individuals with moderate intellectual disability typically have IQ scores ranging from 35 to 49. They often have delays in language development and may have difficulty with abstract thinking and problem-solving. Adaptive Functioning: In terms of adaptive functioning, individuals with moderate intellectual disability often require support in various domains. They may be able to perform some activities of daily living independently, such as feeding and dressing themselves, but they may need assistance with more complex tasks. They may have some communication skills but may struggle with more advanced language and social skills. Social and Practical Skills: Individuals with moderate intellectual disability may have basic social skills and can form relationships with others, but they may struggle with understanding social cues and norms. They may also have some basic practical skills, such as simple household chores, but they may need supervision and support to complete more complex tasks. Educational and Occupational Skills: In terms of education, individuals with moderate intellectual disability may benefit from special education programs that focus on functional skills and life skills. They may be able to learn basic reading, writing, and math skills, but they may require additional support and accommodations. In terms of employment, individuals with moderate intellectual disability may be able to work in supported environments, where they receive assistance and supervision. Overall Functioning: Individuals with moderate intellectual disability typically require some level of support in all areas of life, including personal care, communication, social interactions, and daily activities. With the right support and interventions, they can lead meaningful and fulfilling lives, but they may require ongoing assistance and accommodations to achieve their full potential. 98. What is diagnostic overshadowing? Answer: Diagnostic overshadowing refers to the phenomenon where the presence of a known condition or disability influences the assessment and diagnosis of other conditions. In the context of intellectual disability, diagnostic overshadowing occurs when a person's intellectual disability leads healthcare professionals to overlook or misattribute symptoms of other conditions, such as mental health disorders or physical illnesses. For example, a healthcare provider may attribute symptoms of depression or anxiety in a person with intellectual disability solely to their intellectual disability, without considering that these symptoms may indicate a separate mental health disorder that requires specific treatment. Diagnostic overshadowing can lead to underdiagnosis or misdiagnosis of co-occurring conditions, which can have significant implications for the individual's overall health and well-being. It underscores the importance of comprehensive and careful assessment, especially in individuals with intellectual disabilities, to ensure that all potential conditions are identified and appropriately addressed. 99. Review the social-psychological factors that contribute to the psychological problems of individuals with intellectual disability. What predicts the continuance of externalizing disorders in young children who are developmentally delayed? Answer: Social-Psychological Factors Contributing to Psychological Problems in Individuals with Intellectual Disability: 1. Stigma and Discrimination: Individuals with intellectual disability may face stigma and discrimination, which can impact their self-esteem, social interactions, and access to resources and opportunities. 2. Social Isolation: Limited social skills and difficulties in forming relationships can lead to social isolation, which can contribute to feelings of loneliness and depression. 3. Communication Challenges: Communication difficulties can lead to frustration, misunderstandings, and difficulties in expressing needs and emotions, which can contribute to behavioral problems and psychological distress. 4. Limited Social Support: Lack of social support networks can exacerbate feelings of loneliness and isolation, as well as limit access to coping mechanisms and resources. 5. Environmental Factors: Adverse environmental conditions, such as poverty, family dysfunction, and lack of access to quality healthcare and education, can contribute to psychological problems in individuals with intellectual disability. Predictors of Continuance of Externalizing Disorders in Young Children with Developmental Delay: 1. Severity of Developmental Delay: Children with more severe developmental delay may be at higher risk for continuance of externalizing disorders, as they may have greater difficulty in regulating emotions and behaviors. 2. Family Environment: Family factors, such as parenting style, family stress, and the presence of other psychosocial stressors, can impact the continuance of externalizing disorders in young children with developmental delay. 3. Peer Relationships: Negative peer relationships or social rejection can contribute to the continuance of externalizing disorders, as children may struggle to develop positive social skills and relationships. 4. Co-occurring Mental Health Disorders: The presence of co-occurring mental health disorders, such as anxiety or depression, can increase the risk of continuance of externalizing disorders in young children with developmental delay. 5. Access to Interventions and Support: Early intervention programs and access to appropriate support services can mitigate the risk of continuance of externalizing disorders by addressing underlying issues and promoting positive development. 100. What is the prevalence of intellectual disability? How is prevalence impacted by age, gender and socio-economic status? Answer: The prevalence of intellectual disability (ID) varies depending on the definition and criteria used for diagnosis. According to the World Health Organization (WHO), the global prevalence of ID is estimated to be around 1-3% of the population. However, prevalence rates can differ across age groups, gender, and socio-economic status. Age: The prevalence of ID tends to be higher in children than in adults. This is partly due to the fact that some developmental disabilities may be outgrown or compensated for as individuals mature. Additionally, early intervention programs and advancements in healthcare have improved outcomes for children with intellectual disabilities, reducing the overall prevalence in older age groups. Gender: The prevalence of ID is slightly higher in males than in females. This difference is more pronounced in some specific syndromes or conditions that are associated with intellectual disability, such as fragile X syndrome or Down syndrome. However, the reasons for this gender difference are not entirely clear. Socio-economic Status (SES): There is evidence to suggest that there is a higher prevalence of intellectual disability among individuals from lower socio-economic backgrounds. This may be due to factors such as limited access to quality healthcare, nutrition, and educational resources, as well as higher rates of exposure to environmental risk factors. Overall, while the prevalence of intellectual disability is influenced by age, gender, and socio-economic status, it is important to note that each individual's experience of intellectual disability is unique, and factors such as early intervention, supportive environments, and access to resources can significantly impact outcomes for individuals with ID. 101. Describe the stability, rate and sequence of development for individuals with intellectual disability. Answer: Individuals with intellectual disability (ID) may experience slower or inconsistent development compared to typically developing individuals. Their development can be non-linear, with periods of rapid progress followed by plateaus. The rate and sequence of development vary widely depending on the individual and the specific challenges they face. Early intervention and supportive environments are crucial for promoting positive development and improving outcomes for individuals with ID. 102. Describe the two-group approach to intellectual disability. What are some common characteristics of each group? Answer: The two-group approach categorizes intellectual disability (ID) into mild/moderate and severe/profound. Mild/Moderate ID: • IQ: 50-70 (mild), 35-49 (moderate) • Adaptive Functioning: Better than severe/profound, may need support in complex situations • Communication: Varies, basic to advanced • Social Skills: Basic to moderate, struggles with complex interactions Severe/Profound ID: • IQ: Below 35 (severe), below 20 (profound) • Adaptive Functioning: Extensive support needed in daily life • Communication: Limited, relies on nonverbal or basic language • Social Skills: Limited, struggles with relationships and social situations 103. Discuss how psychosocial variables might play a role in the etiology of intellectual disability, especially mild intellectual disability. Answer: Psychosocial variables can play a significant role in the etiology of intellectual disability, particularly in cases of mild intellectual disability (ID). These variables can interact with genetic, neurological, and environmental factors to influence cognitive development and functioning. Some key psychosocial factors include: 1. Prenatal and Early Childhood Experiences: Exposure to toxins, infections, or trauma during pregnancy can impact brain development and lead to intellectual impairments. Additionally, early childhood experiences, such as neglect, abuse, or lack of stimulation, can affect cognitive development. 2. Parenting Style and Family Environment: The quality of parenting and the family environment can have a profound impact on cognitive development. Positive and supportive environments can promote healthy cognitive development, while negative or stressful environments can hinder it. 3. Socioeconomic Status (SES): Low SES is associated with an increased risk of intellectual disabilities. Factors such as limited access to quality healthcare, nutrition, and educational resources can contribute to cognitive impairments. 4. Education and Stimulation: Adequate education and cognitive stimulation are essential for optimal cognitive development. Lack of access to quality education and intellectual stimulation can contribute to intellectual disabilities. 5. Peer Relationships and Social Integration: Positive peer relationships and social integration can support cognitive development. Individuals with limited social interactions may experience delays in cognitive development. 6. Nutrition and Health: Proper nutrition and overall health are critical for brain development. Malnutrition, exposure to toxins, and untreated medical conditions can contribute to intellectual disabilities. In cases of mild intellectual disability, these psychosocial factors may play a more significant role, as individuals with mild ID often have higher levels of cognitive functioning and may be more susceptible to environmental influences. Early intervention programs that address these psychosocial factors can help mitigate the impact of intellectual disabilities and support optimal cognitive development. 104. List and give examples of the four AAIDD categories of risk and etiology pertaining to intellectual disabilities. Answer: 1. Biological Factors: Genetic conditions (e.g., Down syndrome), prenatal factors (e.g., infections), perinatal factors (e.g., birth complications), and postnatal factors (e.g., head injuries) can contribute to intellectual disabilities. 2. Psychosocial Factors: Neglect, abuse, poor nutrition, and limited educational opportunities can increase the risk of intellectual disabilities. 3. Environmental Factors: Socioeconomic status, exposure to toxins, and lack of early intervention can impact the development of intellectual disabilities. 4. Idiopathic Factors: In some cases, the cause of intellectual disabilities is unknown despite thorough evaluation. 105. Describe the etiology and clinical manifestations of two of the following: Down syndrome, Fragile X syndrome, Williams syndrome, or Prader Willi syndrome. Answer: Down Syndrome: • Etiology: Down syndrome is caused by the presence of an extra copy of chromosome 21, known as trisomy 21. This additional genetic material alters the course of development and results in the characteristics associated with Down syndrome. • Clinical Manifestations: Individuals with Down syndrome often have characteristic physical features, such as a flat facial profile, upward slanting eyes, and a small nose. They may also have developmental delays, intellectual disabilities, and an increased risk of certain medical conditions, such as heart defects, hearing loss, and thyroid problems. Despite these challenges, individuals with Down syndrome can lead fulfilling lives with appropriate support and interventions. Fragile X Syndrome: • Etiology: Fragile X syndrome is caused by a mutation in the FMR1 gene on the X chromosome. This mutation leads to a deficiency in the FMRP protein, which is important for brain development and function. • Clinical Manifestations: Individuals with Fragile X syndrome may have intellectual disabilities ranging from mild to moderate. They may also exhibit behavioral and emotional challenges, such as hyperactivity, anxiety, and social difficulties. Physical features may include a long face, large ears, and a prominent jaw. Additionally, individuals with Fragile X syndrome may have sensory sensitivities and may be at risk for certain medical conditions, such as seizures and connective tissue disorders. Williams Syndrome: • Etiology: Williams syndrome is caused by the deletion of genetic material from chromosome 7. This deletion affects the genes responsible for the development of various systems in the body, including the cardiovascular system and the brain. • Clinical Manifestations: Individuals with Williams syndrome often have a unique combination of traits, including a distinctive facial appearance, cardiovascular abnormalities (such as supravalvular aortic stenosis), intellectual disabilities, and a friendly and outgoing personality. They may also have specific cognitive strengths, such as strong language skills and an affinity for music. However, they may also experience challenges with spatial tasks and abstract reasoning. Prader-Willi Syndrome: • Etiology: Prader-Willi syndrome is caused by the loss of genetic material from a specific region of chromosome 15, which is inherited from the father. This loss leads to a variety of physical, cognitive, and behavioral abnormalities. • Clinical Manifestations: Infants with Prader-Willi syndrome may have poor muscle tone (hypotonia) and feeding difficulties. As they grow older, they may develop an insatiable appetite, which can lead to obesity if not controlled. Individuals with Prader-Willi syndrome may also have intellectual disabilities, behavioral problems (such as obsessive-compulsive behaviors), and hormonal imbalances (such as growth hormone deficiency and hypogonadism). In summary, each of these syndromes has a distinct genetic cause and presents with unique clinical manifestations. Early diagnosis and appropriate interventions can help individuals with these syndromes reach their full potential and improve their quality of life. 106. Report on the stressors that parents and siblings of individuals with intellectual disabilities often face. What factors can affect parent coping? Answer: Stressors Faced by Parents and Siblings of Individuals with Intellectual Disabilities: 1. Emotional Stress: Parents and siblings may experience feelings of grief, guilt, and worry about the future of their loved one with an intellectual disability. 2.

Overall, while caring for a child with an intellectual disability can be challenging, many families find that the rewards far outweigh the difficulties, enriching their lives in profound and meaningful ways. 108. Discuss the changing views of intellectual disability from the late 1700s to present. Answer: Late 1700s - Early 1800s: • Perceived as Moral Deficiency: In the late 1700s and early 1800s, intellectual disability was often viewed as a moral deficiency or a result of divine punishment for sin. This led to the segregation and institutionalization of individuals with intellectual disabilities. Late 1800s - Early 1900s: • Emergence of Medical Models: Towards the late 1800s and early 1900s, there was a shift towards viewing intellectual disability as a medical condition rather than a moral failing. This period saw the rise of eugenics movements, which promoted selective breeding to eliminate intellectual disabilities from the gene pool. Mid-1900s: • Focus on Education and Rehabilitation: In the mid-1900s, there was a growing recognition of the importance of education and rehabilitation for individuals with intellectual disabilities. This led to the establishment of special education programs and the deinstitutionalization movement, which aimed to integrate individuals with disabilities into the community. Late 1900s - Present: • Shift towards Inclusion and Rights: In the late 1900s and continuing into the present day, there has been a strong push towards inclusion and the recognition of the rights of individuals with intellectual disabilities. This has been driven by movements such as the disability rights movement, which advocates for equal rights and opportunities for individuals with disabilities. Current Views: • Focus on Diversity and Inclusion: Today, intellectual disability is increasingly viewed through a lens of diversity and inclusion. There is a greater emphasis on supporting individuals with intellectual disabilities to live fulfilling lives in the community, access education and employment opportunities, and participate fully in society. Overall, the changing views of intellectual disability reflect broader shifts in society's understanding of disability, moving away from a medical or moral model towards a more inclusive and rights-based approach. 109. Review the pros and cons of inclusion for students with intellectual disabilities. Answer: Pros of Inclusion: 1. Social Interaction: Inclusion provides opportunities for students with intellectual disabilities to interact with their peers without disabilities, potentially reducing social isolation and fostering friendships. 2. Improved Self-Esteem: Being included in regular classrooms can boost the self-esteem of students with intellectual disabilities, as they feel accepted and valued by their peers. 3. Academic Benefits: Inclusion can lead to improved academic outcomes for students with intellectual disabilities, as they may have access to the same curriculum and educational resources as their peers. 4. Enhanced Communication Skills: Interacting with peers and teachers in inclusive settings can help students with intellectual disabilities develop their communication skills. 5. Promotes Diversity and Understanding: Inclusion promotes a culture of diversity and understanding, teaching all students to appreciate individual differences. Cons of Inclusion: 1. Lack of Individualized Attention: In inclusive settings, students with intellectual disabilities may not receive the individualized attention and support they need to succeed academically. 2. Negative Peer Interactions: Some students without disabilities may exhibit negative behaviors towards their peers with intellectual disabilities, leading to bullying or social exclusion. 3. Curriculum Challenges: The general curriculum in inclusive classrooms may not always be appropriate or accessible for students with intellectual disabilities, requiring significant modifications. 4. Teacher Preparedness: Teachers may not always have the training or resources needed to effectively support students with intellectual disabilities in inclusive settings. 5. Potential for Stigmatization: Despite efforts to promote inclusivity, there is a risk that students with intellectual disabilities may feel stigmatized or different from their peers in inclusive settings. It's important to note that the effectiveness of inclusion for students with intellectual disabilities can vary depending on individual needs, the level of support available, and the overall school environment. 110. Review the following treatments and discuss the usefulness/effectiveness in regard to the ID population: Positive Behavioral Support (be sure and address functional assessment) and Behavioral Intervention to Enhance Adaptive Behavior or Reduce Maladaptive Behavior (be sure and mention discrete trial learning vs. naturalistic learning). Answer: Positive Behavioral Support (PBS) is a comprehensive approach to addressing challenging behaviors in individuals with intellectual disabilities (ID). It focuses on understanding the function or purpose of a behavior and using this information to develop interventions that teach alternative, more appropriate behaviors. PBS includes a functional behavior assessment (FBA), which is a process used to identify the function of a behavior by examining the antecedents (triggers), behavior itself, and consequences. Functional Assessment: The FBA is a critical component of PBS. It involves collecting data to understand the specific triggers and consequences of a behavior. This helps in developing a behavior support plan that targets the underlying function of the behavior, rather than just trying to suppress the behavior itself. By understanding why a behavior occurs, interventions can be more targeted and effective. Behavioral Intervention to Enhance Adaptive Behavior or Reduce Maladaptive Behavior: This type of intervention focuses on teaching new skills to replace maladaptive behaviors or enhance adaptive behaviors. There are two main approaches to behavioral intervention: discrete trial learning and naturalistic learning. 1. Discrete Trial Learning: This is a structured, teacher-led approach that breaks down skills into smaller, more manageable components. It involves presenting a stimulus, prompting a response, and providing reinforcement for correct responses. Discrete trial learning is often used to teach foundational skills and is highly structured and controlled. 2. Naturalistic Learning: This approach focuses on teaching skills in natural settings and situations. It emphasizes capturing teachable moments and using natural reinforcers. Naturalistic learning is less structured than discrete trial learning and aims to promote generalization of skills to real-life settings. Usefulness/Effectiveness: • Positive Behavioral Support (PBS) has been shown to be effective in reducing challenging behaviors and improving quality of life for individuals with ID. • Functional behavior assessments (FBA) are crucial in developing effective behavior support plans as they help identify the function of the behavior. • Behavioral interventions, including both discrete trial learning and naturalistic learning, can be effective in teaching new skills and reducing maladaptive behaviors. • Discrete trial learning is often used for teaching foundational skills, while naturalistic learning promotes generalization of skills to natural settings. • Both approaches should be tailored to the individual's needs and preferences for the best outcomes. Overall, both Positive Behavioral Support (PBS) and behavioral interventions to enhance adaptive behavior or reduce maladaptive behavior can be highly useful and effective in improving outcomes for individuals with intellectual disabilities.
