Abstract
Dichotic listening (DL) is an auditory task to investigate brain lateralization, or hemispheric asymmetry. DL is the commonest tool to study the dominance of the left-hemisphere for language perception. A wide range of DL paradigms are used to examine hemispheric asymmetry in language processing. DL serves as a valid method in both research and clinical fields (Lezak et al., 2004, Ocklenburg and Güntürkün, 2018). However, almost six decades of research also have revealed a series of experimental variables with systematic modulatory effects on task performance. These variables are a source of systematic error variance in the data and, when uncontrolled, affect the reliability and validity of the obtained laterality measures (Westerhausen, 2019).
