The following article undertakes another analysis of affixation in Polish Sign Language (PJM). This time the question concerns affixes carrying temporal significance. In a previous issue of this journal, negative affixation in PJM was discussed. As it turns out, in addition to these negative morphemes, PJM also possesses suffixes that relate to…

The following article looks into the question of negative affixation in Polish Sign Language. Until today only one negative prefix and one negative suffix were recognized in Polish Sign Language. Our research investigates farther these two affixes looking into their etymologies, constraints and new examples of their use. The negative prefix…

Bimodal bilingualism involves the use of a sign language and a spoken language, and offers a unique opportunity to explore the cognitive effects of growing up bilingual. The aim of this study was to investigate the relationship between bimodal bilingualism and executive function (EF) in hearing children who are native users of a sign language. We…

The aim of this study is twofold: To examine if deafness is invariably associated with deficits in executive function (EF) and to investigate the relationship between sign language proficiency and EF in deaf children of deaf parents with early exposure to a sign language. It is also the first study of EF in children acquiring Polish Sign Language.…

This article describes the project of producing Polish Sign Language (PJM) translations of a series of Polish primary-school textbooks. We discuss the multimedia software application that presents the resulting bilingual textbooks, which allows video clips to be played back by clicking on the corresponding original Polish text. We also explain the…

The evaluation of sign language proficiency needs to be based on measures with well-established psychometric proprieties. To date, no valid and reliable test is available to assess Polish Sign Language ("Polski Jezyk Migowy," PJM) skills in deaf children. Hence, our aim with this study was to adapt the British Sign Language Receptive…

In recent years, research has progressed steadily in regard to the use of computers to recognize and render sign language. This paper reviews significant projects in the field beginning with finger-spelling hands such as "Ralph" (robotics), CyberGloves (virtual reality sensors to capture isolated and continuous signs), camera-based…

The natural sign language used by deaf children in Poland makes no distinction between present, future, and past tenses. Deaf pupils do not understand the notions of temporal sequence and duration of time intervals, and so are prevented from thinking of and planning for the future. The study with 15 deaf 12-year-old pupils and 15 deaf 14-year-old…

The purpose of this article is to analyze the results of a study of the development of analogical reasoning in deaf children coming from two different linguistic environments (deaf children of deaf parents--sign language, deaf children of hearing parents--spoken language) and in hearing children, as well as to compare two groups of deaf children…
