Measuring Verbal Intelligence Using Linguistic Analysis

In this paper we present a study on language use of people with different verbal intelligence. We asked test persons of different ages and educational background to describe the same event. Verbal intelligence was measured using the Hamburg Wechsler Intelligence Test for Adults. The transcribed monologues were analyzed using the DeLite readability checker and different linguistic features used for readability calculations were extracted. The test persons were then divided into two groups according to the results of the intelligence test using the SEM algorithm. For each group the averaged values of the features extracted from the monologues were compared using a one-way analysis of variance.
