This paper aims to describe a Malay version of the Boston Naming Test (MBNT) and its normative data. The M-BNT follows closely the general
administration procedures of the original Boston Naming Test (BNT) but is different in terms of item content. A total of 29 items from the original 60 items
on the test were deemed culturally and linguistically valid for the Malay population and were thus retained. A total of 41 additional items were added
to make a total list of 70 items for pilot testing. These items were first vetted by a panel of experts and then trialed on a sample of 40 Malay adults. Based on
the item analysis from the pilot study, the M-BNT was reduced to a 50 item test. This was administered to 230 normal Malay subjects in five age groups (20 –
29 years, 30 – 39 years, 40 – 49 years, 50 – 59 years, and 60 – 69 years), split into two main educational levels (i.e. < 12 years of education, and 12 years or
more) and across gender. The Malay subjects were chosen representative of the four major geographical regions in West Malaysia. Initial normative data
was computed according to the five age groups and two educational levels. It is hoped that the M-BNT will become a test useful in the identification of patients
with an expressive language word-finding disorder.

The paper describes the validation of the Malay Preschool Language Assessment Tool (MPLAT), a standardized normed referenced language assessment tool for Malay preschoolers within the ages of 4;0-6;11 and whose native language is Malay. The MPLAT (A Razak et al. 2010) is an assessment tool which is designed to assess the areas of receptive language, expressive language and early literacy skills. The MPLAT contains six subtests i.e. picture vocabulary, grammatical understanding, sentence repetition, referential meaning, relational meaning and early literacy skills. This paper is divided into 2 studies. Study 1 tested the psychometric properties and normative data of the diagnostic version of MPLAT on 300 participants recruited from preschools in the rural area of Gua Musang and the urban area of Kota Bahru located in the East Coast state of Kelantan. The construct validity is high with a strong correlation (r = 0.942) between test scores and age, validating the developmental nature of the test. There was also moderate to strong positive correlation between each subtest and the test total, as well as between subtests. It also has high test-retest reliability (r = 0.998 (p < 0.01) and inter-rater reliability (rho = 1.000). The second study looked at the psychometrics properties of the MPLAT short version (screening) compared to the full version diagnostic. The short version of MPLAT is about a quarter of the full (diagnostic) version. About 108 subjects in the urban area of the the Klang Valley, consisting of Kuala Lumpur and Selangor, were administered both versions of the MPLAT. The Pearson correlation revealed a strong positive correlation between the total scores and age (r = 0.718, p<.01), and strong positive correlation for the test-retest reliability (r = 0.881, n=12) for the short MPLAT version. For the full version, the Spearman correlation revealed a strong positive correlation between total scores and age (r = 0.791, p<.01) and a very strong positive Pearson correlation for test-retest reliability (r = 0.943). Cronbach's Alpha values demonstrated the internal consistency of the full version (0.972) and short version (0.929). In summary, both versions of the MPLAT were found to be valid tools to screen and diagnose language problems among Malay preschool children in Malaysia. MPLAT also has the potential to be a useful research tool to delineate language development of the preschool Malay children.

Children with Specific Learning Disorder (SLD) faces challenges in academic areas and are often negatively labelled. The learning problems in SLD children were mainly due to poor phonological skill but not much was known about the contribution of visuospatial difficulties. Therefore, this study aims to determine the relationship between phonological awareness skills and global visual-spatial abilities among Malay speaking children with SLD, and to compare children with SLD and typical readers on intellectual functioning, phonological awareness and global visual-spatial ability. An equal number of typical readers (n = 36) and children with SLD were recruited. Data were coded and analysed using Kendall’s Tau-b, independent samples t-test and Mann-Whitney U test. Results showed phonological skills have strong negative correlation with global visual-spatial ability (r = .55). The typical readers have significantly higher IQ and better phonological skills and better global visual-spatial skills as compared to the group with SLD. However, there is no conclusive evidence due to specificity of more than one area measured by the assessment tools. Nevertheless, it provides a direction for future research to look into global visual-spatial aspects of SLD to aid in educational instruction in the future, in addition to the long-standing phonology deficit theory.

This review aims to present an overview of current research findings on the possible relationship between phonologicalawareness and visual-spatial skills among individuals with dyslexia. Narrative review of the relevant articles wereobtained through computerized searches of databases such as PubMed, PubMed Central (PMC) and Google Scholarwhich included articles from SAGE, Taylor & Francis and Massachusetts Institute of Technology (MIT) Press from theyear 2000 to 2014. The key words were explored, both exclusively and in combination with each other, so as to provide abetter understanding of the relationship between them among individuals with dyslexia. Although it is evident that thereis a phonological deficit in individuals with dyslexia, however, it is inconclusive with regards to the visual-spatial deficitand strength. There is a consensus on the nature of phonological awareness skill deficits but not on the visual spatialabilities in dyslexia. In fact, the relationship between phonological awareness and visual spatial abilities in dyslexia isdependent on the area of visual ability measured.
