The aim of this study was to construct a visual working memory scale that suits different age groups and differentiate the talented students in the Kingdom of Saudi Arabia. The visual-spatial components were used in constructing the visual working memory test (VWMT) which contains 40 questions. Its psychometric properties were verified. The scale was presented to a group of specialized arbitrators to examine the items validity. Testing the construct validity identified a significant (α ≤ 0.05) correlation coefficients between the items and the overall score. Pilot study was conducted on a sample of (56) individuals from different age groups and re-applied four weeks later to evaluate test- retest reliability, the degree of stability of the scale was (0.79), and the coefficient of Cronbach alpha was (0.893), the overall stability coefficient by the half-segmentation method reached (0.855). This proves the validity and reliability of the scale. The (VWMT) revealed good acceptance, reliability, and validity and shows excellent psychometric properties. The scale also was applied to a sample of (540) individuals whose ages ranged between (6) to (30) to distinguish the talented in working memory from the normal ones. The results revealed that there were statistically significant differences (α ≤ 0.05) in working memory for the benefit of the higher age group, and the study recommended applying the scale to different samples to reduce the challenges facing education, and also recommended conducting more studies in this field.
