Resumen
Los cambios en la percepción del habla, incluso de sonidos no vocales, pueden alterar la producción del habla. Esto desafía los modelos existentes de control motor del habla e interacciones sensoriomotoras.
Área de la Ciencia:
- Psicolingüística
- Ciencia del Habla
- Neurociencia Auditiva
Sus antecedentes:
- Creciente evidencia vincula los cambios a corto plazo en la percepción del habla con la producción del habla.
- La convergencia fonética describe la alineación de patrones del habla entre los compañeros de comunicación.
Objetivo del estudio:
- Investigar las representaciones subyacentes de los efectos perceptuales en la producción del habla.
- Determinar si la alteración de la percepción del habla influye en los patrones de producción del habla.
Principales métodos:
- Tres experimentos que manipulan el contexto auditivo para cambiar la percepción del habla.
- Análisis de los patrones acústicos de la producción del habla después de los cambios perceptuales.
Principales resultados:
- Los contextos articulatorio-fonéticos alteraron tanto la percepción como la producción del habla.
- El habla natural filtrada (sin cambios fonéticos) también afectó la percepción y la producción.
- Los tonos no vocales indujeron efectos perceptuales que influyeron en la producción del habla.
Conclusiones:
- La transferencia percepción-producción es más amplia de lo que se pensaba anteriormente.
- Desafía la necesidad de interacción social, imitación o detalle fonético para el habla sensoriomotora.
- Recomienda extender los modelos de control motor del habla para incluir influencias perceptuales y procesos auditivos generales.

Higher Mental Functions of the Brain: Language
3.4K
Language is a system of communication that allows the expression of thoughts, ideas, and feelings. The brain processes language in both hemispheres.
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...

Hierarchy of Motor Control
5.9K
The hierarchy of motor control refers to the different levels of organization and processing involved in controlling movement in the body. These levels range from higher cortical areas involved in planning and decision-making to lower spinal cord reflexes that respond automatically to external stimuli.

Motor and Sensory Areas of the Cortex
6.9K
The cerebral cortex, the brain's outermost layer, is pivotal in processing complex cognitive tasks, emotions, and various sensory inputs and executing voluntary motor activities. This intricate structure is divided into three primary functional areas: the motor areas, sensory areas, and association areas.
Motor Areas
The motor areas located in the frontal lobe are central to controlling voluntary movements. This region is further subdivided into the primary motor cortex and the premotor cortex....

Brainstem
5.7K
The brainstem, located inferior to the brain and superior to the spinal cord, serves as a bridge between the cerebrum and the spinal cord. It plays a vital role in relaying information and controlling critical life functions. It comprises three primary regions: the midbrain, pons, and medulla oblongata.
The Midbrain
The midbrain is located beneath the diencephalon and connects the cerebrum with the lower parts of the brain. The cerebral peduncles are prominent midbrain structures that house the...

Major Somatic Sensory Pathways
2.4K
Sensory impulses related to touch, pressure, vibration, and proprioception from various body parts, such as the limbs, trunk, neck, and posterior head, travel to the cerebral cortex through the posterior column-medial lemniscus pathway. The pathway’s name derives from the two white-matter tracts that convey the impulses: the spinal cord's posterior column and the brainstem's medial lemniscus. First-order sensory neurons extend their axons into the spinal cord, forming the...

Auditory Pathway
7.1K
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.
