Right Hemisphere Language Battery in Hindi

Abstract

Communicative deficits are identified by the Speech-Language Pathologists (SLPs) which are otherwise attributed to a loss of memory, attention, or visual-perceptual skills. Tools to measure right hemisphere functions have been developed in only two Indian languages (Kannada and Malayalam), but no test has been developed in Hindi. Hundred participants were considered for the study. They were divided into three groups- eighty normal participants (Group-I) and ten Hindi speaking diagnosed right hemisphere vascular damaged participants (Group- II) and ten Hindi speaking diagnosed left hemisphere vascular damaged participants (Group-III). There is no significant difference existed between the performance of the participants between Right Hemisphere Language Battery (RHLB) and Right Hemisphere Language Battery in Hindi (RHLB-H) across all the subtests at α = 0.05 level of significance. A significant difference exists between the obtained mean scores among the normal control participants and Right Hemisphere Disorder (RHD) participants at α = 0.05 level significance. ANOVA test results showed that RHD participants had a significantly higher discourse error rating than either Left Hemisphere Disorder (LHD) or controls. Furthermore, the Tukey’s Honest Significant Difference (HSD) Post-Hoc test reveals that there is a decrease in the obtained mean scores from Normal Control participants to the LHD and RHD groups in order. It can thus be concluded that there is a significant difference in the mean scores across all the three groups
