Development of Bengali Audio-Visual Test Battery for Assessment of Pragmatic Skills: Preliminary Normative Data Based on Educational Level.

Pragmatic competence may be disrupted due to psychological and neurological causes. For appropriate remedy and rehabilitation, a precise assessment of pragmatic skills is important. However, there is no test battery in the Bengali language, and consequently, there is no published data on pragmatic ability of Bengali speakers. Due to the vast diversity of the population, it becomes increasingly difficult to assess pragmatic ability of an individual without a proper knowledge of the normal variations. To address this problem we have developed a test battery in Bengali, and to begin with, we have administered it to one hundred and five (105) normal healthy persons having different levels of education. The four groups having 17 years and above, 15 to < 17 years, 12 to < 15 years and 10 to < 12 years of education yielded a normative score of 193, 189, 171 and 150, respectively. These normative scores will allow clinicians to make a proper assessment of patients suffering from pragmatic deficits and help avoid interpreting social differences as neurological deficits.
