Speech processing ability in alcoholics: a transient impairment and its relation to field dependence

Area of Science:

• Neuroscience
• Psychology

Background:

• Alcoholism is associated with cognitive impairments.
• Understanding the relationship between alcoholism and perceptual abilities is crucial.

Purpose of the Study:

• To investigate the relationship between alcoholism, speech processing, and field dependence.
• To determine if field dependence is a cause or consequence of alcoholism.

Main Methods:

• Administered Synthetic Sentence Identification (SSI) and Embedded-Figures Test (EFT) to alcoholic and non-alcoholic subjects.
• Analyzed cross-sectional and longitudinal data.

Main Results:

• No significant correlation between speech processing (auditory figure-ground differentiation) and field dependence.
• Recently-drinking alcoholics exhibited temporary impairments in speech processing.
• Speech processing ability improved after several months of alcohol abstinence.
• A correlation was found between the chronicity of alcoholism and field dependence.

Conclusions:

• Temporary deficits in speech processing are linked to recent alcohol consumption.
• Field dependence may be a consequence rather than a precursor of alcoholism.
• Further research is needed to clarify the causality of field dependence in alcoholism.
