Comparing monotic and diotic selective auditory attention abilities in children

Area of Science:

• Audiology
• Neuroscience
• Developmental Psychology

Background:

• Auditory processing ability is often assessed using speech recognition tasks.
• Normative data for these tasks typically relies on diotic administration (both ears simultaneously).
• The impact of monotic (one ear) versus diotic administration on test results is not fully understood.

Purpose of the Study:

• To investigate if monotic and diotic administrations of the Selective Auditory Attention Test yield similar results.
• To compare ear-specific performance in auditory processing ability between monotic and diotic conditions.

Main Methods:

• Seventy-two typically developing children participated in the study.
• Children were tested using the Selective Auditory Attention Test under both monotic and diotic conditions.
• A counterbalanced, repeated measures design was employed.

Main Results:

• Diotic administration resulted in significantly higher speech recognition scores compared to monotic administration.
• No significant differences were observed between the performance of the right and left ears.
• A binaural advantage was suggested under challenging listening conditions.

Conclusions:

• Ear-specific normative data is crucial for accurate auditory processing ability assessments.
• Extrapolating normative data from diotic tests to monotic conditions may be misleading.
• The practice of ear occlusion for children with (central) auditory processing disorder should be re-evaluated due to potential binaural advantages.
