Language and Cognition

Language and Cognition

Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.

Cognitive Development During Adulthood

Cognitive Development During Adulthood

Cognitive development continues throughout adulthood, undergoing significant shifts across early, middle, and late stages. Individual transition occurs from adolescent idealism to pragmatic and adaptable thinking in early adulthood. During this period, individuals learn to integrate personal beliefs with the recognition that other perspectives are equally valid. Exposure to the complexities of modern society, diverse experiences, and higher education contribute to this adaptive thought process,...

Summary

Auditory assessments can predict neurocognitive deficits in people living with HIV (PLWH). Machine learning models using auditory data significantly improved prediction accuracy compared to demographic factors alone, offering potential for early intervention.

Neuroscience
Infectious Diseases
Machine Learning

Background:

Cognitive dysfunction is a concern in people living with HIV (PLWH), particularly in low-resource settings.
Early detection of cognitive impairment is crucial for timely intervention.
The predictive value of auditory assessments for neurocognitive deficits, beyond demographics, requires further investigation.

Purpose of the Study:

To utilize machine learning to predict neurocognitive deficits.
To evaluate the efficacy of auditory tests and demographic factors in predicting cognitive impairment.

Main Methods:

A longitudinal study was conducted in Dar es Salaam, Tanzania, involving 478 participants (349 PLWH, 129 HIV-negative).
Machine learning algorithms were trained and tested using auditory variables and demographic data.
Neurocognitive dysfunction was defined as a score <26 on the Kiswahili Montreal Cognitive Assessment.

Main Results:

Machine learning models incorporating auditory variables demonstrated superior prediction of neurocognitive deficits.
Gaussian and kernel naïve Bayes classifiers showed high predictive performance, with AUC values of 0.91 and 0.87, respectively.
Models without auditory features performed significantly worse (p < .001), highlighting the incremental predictive value of auditory assessments.

Conclusions:

Auditory variables significantly enhance the prediction of cognitive function.
Easy-to-administer auditory tests can serve as objective predictors of neurocognitive performance, suitable for global application.
Further research into machine learning algorithms for predicting cognitive outcomes is warranted.
