| Summary: | Visual perceptual skills are important skills for an adult to carry out their daily activities
such as reading, writing and driving, successfully. This study was conducted to
determine the visual perceptual skills (non-motor) of a group of adults in Selangor,
Malaysia. A total of 120 subjects from Selangor with the age ranging from 20 to
59 years were randomly recruited in this cross-sectional study. This study involved
distance and near visual acuity measurements using Snellen chart and Universiti
Kebangsaan Malaysia (UKM) near vision chart, cognitive screening tests using the
Mini Mental State Examination questionnaire (MMSE) as well as visual perceptual
skills assessment (non-motor) using the Test of Visual Perceptual Skills (Non-Motor)-
Revised (TVPS-R). The mean age of the subjects was 39.41+11.81 years old. Results
showed that the mean standard scored obtained for Visual Discrimination (VD),
Visual Memory (VM), Visual-Spatial Relationships (VSR), Visual Form Constancy
(VFC), Visual Sequential Memory (VSM), Visual Figure-Ground (VFG) and Visual
Closure (VC) subtests were 14.12+1.10, 13.42+1.58, 14.53+1.26, 12.47+1.03,
12.35+2.26, 13.67+1.64 and 13.73+2.23, respectively. Analysis of ANOVA shows
that the VD, VM, and VSM scores are influenced by educational level (p<0.05).
Pearson correlation showed a significant negative correlation between all the
sub-tests of TVPS-R scores with age variation (p<0.05) except the VFC. Linear
regression showed significant negative relationship between VD, VM, VSR and
VSM with age. This research provided normative data of TVPS-R test on Malaysian
adults for future reference and study. |
