Summary
This study established reference data for auditory and oral sensory skills in children aged 9-15. Findings provide a baseline for assessing children with residual speech sound disorder (RSSD) and inform customized treatment recommendations.
Area of Science:
- Speech-language pathology
- Developmental psychology
- Auditory and somatosensory neuroscience
Background:
- Children with residual speech sound disorder (RSSD) often have underlying sensory processing deficits.
- Establishing normative sensory data is crucial for accurate diagnosis and targeted intervention in pediatric speech disorders.
Purpose of the Study:
- To collect normative data on auditory-perceptual and oral somatosensory acuity in typically developing children (9-15 years).
- To examine the relationship between age and sensory performance, and potential trade-offs between auditory and somatosensory domains.
- To provide a basis for comparison for individuals with RSSD, particularly those affecting American English rhotics.
Main Methods:
- Ninety-eight children (9-15 years) completed auditory tasks (stimulus identification/discrimination, category goodness) and oral somatosensory tasks (bite block, stereognosis, articulatory awareness).
- Concurrent validity between tasks and associations with age were analyzed.
- Composite measures were used to investigate sensory trade-offs.
Main Results:
- Significant associations were found between auditory identification/discrimination and oral tasks (bite block, articulatory awareness).
- Age-related improvements were observed in category goodness and bite block tasks.
- No significant trade-off was detected between auditory-perceptual and somatosensory performance.
Conclusions:
- This study offers a comprehensive characterization of speech-related sensory function in older children and adolescents.
- Shared data and methods can aid in developing customized treatment plans for children with RSSD based on individual sensory profiles.
- Normative data are essential for understanding sensory contributions to speech sound disorders.

01:22Language Development

Children master language quickly and with relative ease, supported by both biological predisposition and reinforcement. B. F. Skinner (1957) proposed that language is learned through reinforcement, while Noam Chomsky (1965) argued that language acquisition mechanisms are biologically determined.
The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...

When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.

01:33Somatosensation
36.9K
The somatosensory system relays sensory information from the skin, mucous membranes, limbs, and joints. Somatosensation is more familiarly known as the sense of touch. A typical somatosensory pathway includes three types of long neurons: primary, secondary, and tertiary. Primary neurons have cell bodies located near the spinal cord in groups of neurons called dorsal root ganglia. The sensory neurons of ganglia innervate designated areas of skin called dermatomes.

01:15Auditory Pathway
5.6K
Auditory pathways constitute the complex neural circuits responsible for transmitting and interpreting auditory information from the peripheral auditory system to the brain. Sound waves are initially captured by the outer ear, funneled through the ear canal, and reach the tympanic membrane (eardrum). These vibrations are transmitted via the middle ear's ossicles to the inner ear's cochlea.

The somatosensory cortex in the parietal lobes is crucial for interpreting sensory data such as touch, temperature, and proprioception. The somatosensory cortex, situated in the parietal lobes, plays a vital role in interpreting sensory information like touch, temperature, and proprioception—awareness of body position. This specialized brain region features an organized structure wherein neurons at the top primarily process sensations originating from the lower body. In contrast, those at...

01:11Sensory Perception: Organization of the Somatosensory System
3.2K
The somatosensory system is the central and peripheral nervous system component that senses and processes touch, pressure, pain, temperature, and body position or proprioception. The process of sensation takes place at three levels:
The receptor level:
The receptor level is the first stage of sensation. It involves the detection of a stimulus by specialized sensory receptors. The stimulus must arrive within the receptor's receptive field. Next, the receptor converts the energy of the...
