Higher Mental Functions of the Brain: Language01:10

Higher Mental Functions of the Brain: Language

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...
Negative and Cognitive Symptoms of Schizophrenia01:30

Negative and Cognitive Symptoms of Schizophrenia

Negative symptoms of schizophrenia indicate a reduction or absence of typical behaviors and emotional responses found in healthy individuals, while positive symptoms reflect an excess or distortion of normal functioning.
Negative Symptoms
Negative symptoms of schizophrenia manifest as deficits in normal emotional and behavioral functioning, profoundly impacting daily life. Individuals with schizophrenia often display a flat affect, characterized by a near-total absence of emotional expression,...
Dissociative Amnesia01:21

Dissociative Amnesia

Dissociative amnesia is a complex psychological condition that manifests as an inability to recall personal information, often tied to traumatic or stressful events. Unlike general amnesia, individuals with this condition retain the ability to perform routine activities and procedural tasks, such as operating a phone or navigating public transportation, yet experience profound gaps in autobiographical memory. These lapses may encompass significant life events, such as suicide attempts or...
Visual Agnosia01:12

Visual Agnosia

Visual agnosia is a condition characterized by the inability to recognize visually presented objects despite having normal vision. For instance, a person with visual agnosia can describe the shape and color of an object but cannot identify or name it. This impairment does not affect their visual field, acuity, color vision, brightness discrimination, language, or memory. An example of this condition in a social setting is someone at a dinner party asking for "that silver thing with a round end"...
Amnesia01:13

Amnesia

Amnesia is a condition marked by long-term memory loss, which impairs the ability to recall past events or create new memories.
The severity and duration of memory loss vary depending on the type and underlying cause. Amnesia is classified into two main types: retrograde and anterograde.
Retrograde amnesia is marked by the loss of memories formed before the onset of the condition. Patients may recall distant past events but often forget those occurring shortly before the incident.
Anterograde...
Amyloid Fibrils03:03

Amyloid Fibrils

Amyloid fibrils are aggregates of misfolded proteins.  Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils. 
Amyloid deposits were observed as early as 1639 in the liver and the spleen.   In 1854, Rudolph Virchow performed iodine staining, normally used to...

Summary

Anomic aphasia, a language disorder, impairs narrative coherence by affecting lexical retrieval. This study reveals lexical deficits directly impact macrolinguistic skills in individuals with anomia.

Area of Science:

  • Neuroscience
  • Psycholinguistics
  • Speech and Language Pathology

Background:

  • Anomic aphasia primarily affects lexical retrieval, but its impact on narrative construction remains debated.
  • It is unclear if macrolinguistic difficulties in anomia stem from the disorder itself or from lexical impairments.

Purpose of the Study:

  • To investigate the influence of lexical retrieval deficits on macrolinguistic processing in narrative production.
  • To compare narrative skills between individuals with chronic anomic aphasia and healthy controls.

Main Methods:

  • Compared narrative production in 10 individuals with anomic aphasia and 10 matched healthy controls.
  • Analyzed speech rate, utterance length, sentence grammaticality, semantic paraphasias, cohesion, global coherence, and lexical information units.

Utilizing Repetitive Transcranial Magnetic Stimulation to Improve Language Function in Stroke Patients with Chronic Non-fluent Aphasia

Published on: July 2, 2013

Main Results:

  • Anomic participants exhibited reduced speech rate, shorter utterances, fewer complete sentences, and more semantic paraphasias.
  • Macrolinguistic analysis revealed increased cohesion and global coherence errors, and fewer lexical information units in the anomic group.
  • Correlations indicated lexical retrieval issues negatively impact sentence completeness, cohesion, and global coherence.

Conclusions:

  • Lexical retrieval deficits in anomic aphasia significantly impair macrolinguistic processing during narrative construction.
  • Interrupted utterances due to lexical retrieval difficulties reduce sentence completeness and cohesion.
  • Coping strategies for lexical impairment lead to fillers and repetitions, further reducing global coherence.
