Abstract
The current study aimed to construct Battery of a Developmental
Aptitude Diagnostics Scales (Attention-Perception-Memory) for primary
school students in the Kingdom of Bahrain norms for the performance of age
groups (6.5-13) on battery scales. The tool consisted of 19 subscales
distributed under three main dimensions: attention, perception, and memory.
The study followed the descriptive survey method in a stratified, multi-stage
random sampling method. The initial version of the battery applied in 3 pilot
samples totaling (540) to reach the battery's initial characteristics and verify
the indicators of validity and reliability of the scores obtained from the
battery scales. The basic standardization sample consisted of (2417)
students. The results showed coefficient's validity ranged between (0.50-
0.82), and the coefficients of reliability values ranged between (0.88 -0.60).
It also found differences in performance on DADS battery scales, with
increasing age, in favor of the older age group. The study recommended
adopting the DADS battery and its application in the uses for which it
developed.
Keywords: standardization, battery, developmental aptitude, attention,
perception, memory.
