Effects of Lexical Density and Lexical Variety in Language

Performance and Proficiency

ABSTRACT

The aim of the present study is to explore the effects of lexical density and lexical variety in language 

performance and proficiency of the written scripts of tenth 

class regional medium students. The exam scripts are 

collected as data, the learners aged between 14 and 16

years. The main purpose of the study is to establish the use 

of lexicon in the written scripts would exhibit language 

knowledge of the learners. The cognitive theory of 

learning used in the present study to ascertain the use of 

measures i.e. lexical density and variety would aid in the 

language learning. Brown’s (1973) observations showed 

that there was a predictable order of acquisition of certain 

morpheme in English. Jean Ure’s (1971) basic method of 

lexical density is used to analyze the data. Robinson’s 

(1995) measure of complexity is used to find out the 

lexical variety. This reliable and valid measure of lexical 

density and variety in the written scripts will be useful for 

determining the factors that affect the language 

performance and proficiency which is related lexicon.
