A dataset of subjective frequency estimates of the words of the peabody vocabulary test by Arabic-English bilingual speakers.

Abstract

A data set was developed for research on word recognition and comprehension as well as for vocabulary knowledge estimation of Arabic-English bilingual speakers (i.e., an understudied population). Subjective frequency (i.e., familiarity) ratings, which reflect language exposure, were collected from 1000 Arabic-English speakers (age range: 18-25) for the printed words of the Peabody Picture Vocabulary Test (PPVT). They were obtained from speakers who had received at least a score of 6 (i.e., competent user of the English language) on the International English Language Testing System (i.e., IELTS). Reading comprehension scores were also obtained from 61 speakers from the same population. In the developed data set, printed words are displayed with their subjective frequency ratings and comprehension scores alongside objective word properties.
