Your assignment is to prepare and submit a paper on learning sign language. SLN De.: Sign Language of the Netherlands, p. 520, C.2, L.1), PHS De.: Parental Hearing Status, p. 520, C.2, L. 10) and LP De.: Language Preference, p. 520, C.2, L.11)were defined appropriately in the article. The sample consisted of 87 deaf children (50 boys and 37 girls). All the participants had a hearing impairment over 80 decibels, diagnosed with deafness before the age of 3 years, had normal nonverbal intelligence and had no other known impairments (p.521, C.1, L.1-6). The settings were five special schools for deaf children in Netherlands and information regarding students’ use of SLN, Sign Supported Dutch (SSD) and spoken Dutch was taken from their teachers in individual questionnaires (p. 521, C.1, L.2, 27). The research design comprised of two reading vocabulary tests and a written comprehension tests in spoken Dutch and SLN followed by questions appearing on computer screens open-ended questions (p.521, C.2, L.1-6. p.522, C.1, L. 4-8). The reliability of the sign language tests was administered with the help of Cronbach’s alpha coefficients. For tabulation purposes, various SPSS tools were used (p. 522, C.1., L.31). Further factors related to short-term memory were also considered in tabulating results. For treatment, TaaltestAlleKinderen (TAK-R) was used which is a test battery for the assessment of Dutch spoken language skills of hearing children and sign language tests were used (p.521, C.2, L. 22). The research findings indicated that there is a positive relationship between vocabulary in SLN and written Dutch (p. 525, C.2, L. 12). Another finding was that deaf children of deaf parents have earlier and more intensive contact with SLN and, therefore, should score higher on the vocabulary and story comprehension tasks in SLN (p. 527, C.1, L. 11). As far as the impact of LP is concerned, deaf children who exclusively prefer SLN will be more proficient in SLN compared to deaf children who do not exclusively prefer SLN (p. 527, C.1, L. 23).
