Summary of "Aerobic fitness relates to differential attentional but not language-related cognitive processes."

Compelling evidence supports an association between the attribute of aerobic fitness and achievement scores on standardized tests of reading. However, such standardized assessments provide only a broad valuation of a complex network of language related sub-processes that contribute to reading and are heavily confounded by other attention-related processes. The present investigation sought to clarify the nature of the association between aerobic fitness and language processing in a sample of college-aged adults. Participants were bifurcated based on aerobic fitness level and on a separate day were asked to complete a lexical decision task while neuroelectric activity was recorded. Analysis of word-level language-related ERP components revealed no fitness differences. However, lower aerobically-fit individuals elicited smaller amplitude for attention-related ERP components relative to the higher aerobically-fit group. These data provide initial evidence to suggest that fitness-related differences in reading achievement may result from attentional processes rather than acting upon specific language-related processes.

Medical and Biotech [MESH] Definitions

A neuropsychological test designed to assess different memory functions. It may incorporate an optional cognitive exam (Brief Cognitive Status Exam) that helps to assess memory related cognitive function.

A cognitive disorder marked by an impaired ability to comprehend or express language in its written or spoken form. This condition is caused by diseases which affect the language areas of the dominant hemisphere. Clinical features are used to classify the various subtypes of this condition. General categories include receptive, expressive, and mixed forms of aphasia.

Temporary visual deficit or impaired visual processing occurring in a rapid serial visual presentation task. After a person identifies the first of two visual targets, the ability to detect the second target is impaired for the next few hundred milliseconds. This phenomenon is called attentional blink.

Tests designed to assess language behavior and abilities. They include tests of vocabulary, comprehension, grammar and functional use of language, e.g., Development Sentence Scoring, Receptive-Expressive Emergent Language Scale, Parsons Language Sample, Utah Test of Language Development, Michigan Language Inventory and Verbal Language Development Scale, Illinois Test of Psycholinguistic Abilities, Northwestern Syntax Screening Test, Peabody Picture Vocabulary Test, Ammons Full-Range Picture Vocabulary Test, and Assessment of Children's Language Comprehension.

A progressive form of dementia characterized by the global loss of language abilities and initial preservation of other cognitive functions. Fluent and nonfluent subtypes have been described. Eventually a pattern of global cognitive dysfunction, similar to ALZHEIMER DISEASE, emerges. Pathologically, there are no Alzheimer or PICK DISEASE like changes, however, spongiform changes of cortical layers II and III are present in the TEMPORAL LOBE and FRONTAL LOBE.
