Resumen
Los adultos que tartamudean (AWS) muestran una fluidez fonémica y un control ejecutivo más débiles en comparación con los adultos que no tartamudean (AWNS). Sus habilidades de almacenamiento y organización de palabras parecen intactas, lo que sugiere desafíos específicos en el acceso a la información fonológica.
Área de la Ciencia:
- Patología del Habla y del Lenguaje
- Neurociencia Cognitiva
- Psicolingüística
Sus antecedentes:
- La tartamudez (AWS) es un trastorno complejo que afecta la fluidez del habla.
- Las funciones ejecutivas y el acceso léxico son cruciales para la producción fluida del habla.
Objetivo del estudio:
- Investigar el acceso léxico y el control ejecutivo en adultos que tartamudean (AWS) y adultos que no tartamudean (AWNS).
- Identificar procesos cognitivos específicos que son desafiantes para los AWS, contribuyendo a sus dificultades del habla.
Principales métodos:
- Los participantes completaron tareas de fluidez fonémica y semántica.
- Se analizó el rendimiento basándose en respuestas precisas, agrupación y cambios entre categorías de respuesta.
Principales resultados:
- Los AWS produjeron menos respuestas precisas en fluidez fonémica en comparación con los AWNS.
- No se observaron diferencias significativas en la agrupación entre AWS y AWNS.
- Los AWS exhibieron significativamente menos cambios que los AWNS.
Conclusiones:
- Los AWS demuestran un acceso léxico y un control ejecutivo más débiles basados en fonemas en comparación con los AWNS.
- Los hallazgos sugieren que los desafíos en el acceso a la información fonológica contribuyen a la tartamudez.
- El almacenamiento de palabras y la organización de la información semántica parecen no verse afectados en los AWS.

01:20Taste Buds and Receptors
5.6K
Gustation, or the sense of taste, is intrinsically linked to the anatomical structures located on the tongue. This organ's surface, along with the entirety of the oral cavity, is adorned with stratified squamous epithelium. Evident on the tongue are elevated structures known as papillae (singular = papilla), which house the mechanisms for the transduction of gustatory stimuli. Four distinct types of papillae exist, each identified by their unique morphological attributes: the circumvallate,...

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

01:25Deglutition
7.7K
Swallowing, otherwise known as deglutition, facilitates the transport of food from the mouth to the stomach. It is a multifaceted process that involves both the tongue and the muscles of the throat and esophagus. Saliva and mucus aid in this process, which takes approximately 4 to 8 seconds for semi-solid or solid food and around 1 second for liquids or very soft food.
Swallowing can be divided into three stages: the voluntary phase, the pharyngeal phase, and the esophageal phase. Although the...

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...

01:16Psychosexual Stages of Personality: Oral
3.9K
The oral stage is the initial phase of Sigmund Freud's theory of psychosexual development, occurring from birth to approximately 12 to 18 months. During this period, the infant's mouth serves as the primary source of pleasure, with actions such as sucking, chewing, biting, and drinking playing a crucial role in reducing tension. These activities are essential not only for nourishment but also for the infant's psychological and emotional satisfaction.

1.1K
Bulimia nervosa is a complex and severe eating disorder characterized by a cyclical pattern of binge-and-purge eating pattern. It generally involves an episode of binge eating, followed by compensatory behaviors such as vomiting, excessive exercise, laxative use, or fasting, to prevent weight gain. Despite often maintaining a normal weight, individuals with bulimia are intensely preoccupied with their body image and harbor an overwhelming fear of gaining weight. This can contribute to the...
