A Case Study on Vocal Loudness With a Young Adult With Autism Spectrum Disorder and Developmental Delay
American Journal of Speech-Language Pathology
|August 9, 2015
Summary
This study shows that a young adult with autism spectrum disorder (ASD) and developmental delay significantly improved vocal loudness control. The intervention demonstrated effective generalization of skills in a group setting.
Area of Science:
- Speech-Language Pathology
- Developmental Disabilities Research
Background:
- Autism spectrum disorder (ASD) and developmental delay can impact speech and communication skills.
- Vocal loudness regulation is a crucial aspect of communicative competence.
Observation:
- A case study involving a young adult with ASD and developmental delay focused on reducing vocal loudness.
- Intervention included individual sessions with feedback and generalization in a group setting.
Findings:
- The participant's spontaneous speech volume improved from 42% to 92% of utterances during individual treatment.
- Generalization of appropriate vocal loudness was observed in the group setting post-treatment.
Implications:
- This case study highlights the importance of addressing suprasegmental features in communication interventions.
- Further research and services are needed for young adults with developmental disabilities to enhance communicative competence.

Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

01:26Modeling in Therapy
721
Modeling, a key technique in therapy, uses observational learning to help clients acquire and practice new skills by watching therapists demonstrate desired behaviors. This approach, rooted in Albert Bandura's concept of vicarious learning, plays a significant role in therapeutic interventions for various psychological conditions, including social anxiety, ADHD, and depression.

01:25Learning Disabilities
741
Learning disabilities are cognitive disorders caused by neurological impairments that affect cognitive functions like language and reading, without indicating overall intellectual or developmental challenges. These disabilities differ from global intellectual or developmental disabilities as they are limited to distinct cognitive functions. Common learning disabilities include dysgraphia, dyslexia, and dyscalculia, each of which impacts unique aspects of learning.

01:21Perceiving Loudness, Pitch, and Location
1.3K
The human brain perceives pitch through two primary mechanisms reflected in place theory and frequency theory. Each mechanism describes how sound waves are interpreted as specific pitches by the brain, offering insights into the intricate processes of auditory perception.
Place theory, or place coding, suggests that different pitches are heard because various sound waves activate specific locations along the cochlea's basilar membrane. The brain determines the pitch of a sound by...

The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids,...

Conduct disorder is a complex mental health diagnosis characterized by a repetitive and persistent pattern of behavior that violates societal norms, the rights of others, or age-appropriate rules. The diagnostic criteria for conduct disorder require the presence of at least three problematic behaviors within the past 12 months, with at least one occurring in the past six months. These behaviors are grouped into four categories: aggression toward people and animals; destruction of property;...
