Phonological loop

The phonological loop, also called the phonetic loop or the articulatory loop, is the part of working memory that rehearses verbal information. It consists of two parts: a short-term phonological store with auditory memory traces that are subject to rapid decay and an articulatory rehearsal component that can revive the memory traces.The first component is a phonological memory store which can hold traces of acoustic or speech based material. Material in this short term store lasts about two seconds unless it is maintained through the use of the second subcomponent, articulatory subvocal rehearsal. Prevention of articulatory rehearsal results in very rapid forgetting (a process known as decay). When a song or tune gets latched onto the phonological loop, it is rehearsed in a constant loop. This is to prevent decay. This explains why sometimes, you can't seem to get a song out of your head. The best way to overcome this phenomenon is to distract your attention away from the tune. This will allow the natural process of decay to rapidly set in on the memory, thereby ending the rehearsal process. Se supone que cualquier información verbal auditiva entra automáticamente en el almacén fonológico.. El lenguaje presentado visualmente puede transformarse en código fonológico mediante la articulación silenciosa y, por lo tanto, codificarse en el almacén fonológico.. This transformation is facilitated by the articulatory control process. El almacén fonológico actúa como un 'oído interno', recordar los sonidos del habla en su orden temporal, mientras que el proceso articulatorio actúa como una 'voz interior' y repite la serie de palabras (u otros elementos del habla) on a loop to prevent them from decaying. The phonological loop may play a key role in the acquisition of vocabulary, particularly in the early childhood years.[1] It may also be vital for learning a second language. Five main findings provide evidence for the phonological loop: El efecto de la similitud fonológica: Las listas de palabras que suenan similares son más difíciles de recordar que las palabras que suenan diferente.. similitud semántica (similitud de significado) tiene un efecto relativamente pequeño, supporting the assumption that verbal information is coded largely phonologically in working memory.[2] El efecto de la supresión articulatoria: La memoria para el material verbal se ve afectada cuando se le pide a la gente que diga algo irrelevante en voz alta.. Se supone que esto bloquea el proceso de ensayo articulatorio., thereby leaving memory traces in the phonological loop to decay.[3] Transfer of information between codes: With visually presented items, adults usually name and sub-vocally rehearse them, so the information is transferred from a visual to an auditory code. Articulatory suppression prevents this transfer, and in that case the above mentioned effect of phonological similarity is erased for visually presented items.[4] Neuropsychological evidence: A defective phonological store explains the behavior of patients with a specific deficit in phonological short-term memory. Aphasic patients with dyspraxia are unable to set up the speech motor codes necessary for articulation, caused by a deficiency of the articulatory rehearsal process.[5] Por otro lado, patients with dysarthria, whose speech problems are secondary, show a normal capacity for rehearsal. This suggests that it is the subvocal rehearsing that is crucial.[6] Contenido 1 Ver también 2 References & Bibliography 3 Textos clave 3.1 Libros 3.2 Papeles 4 Material adicional 4.1 Libros 4.2 Papeles 5 External links See also Baddeley's model of working memory References & Bibliography ↑ Baddeley A, Gathercole S, Papagno C (Enero 1998).
