Abstract
This study aimed to adapt Cognitive Abilities Scale-2 (CAS-2) Preschool (24-47 months) Form into Turkish by focusing on 24-36-month children and conduct validity and reliability studies. The study utilized the survey model and a study group which consisted of 60 socio-culturally disadvantaged 24-36-month children in Bolu province. CAS-2 Preschool Form includes five subscales: oral language, reading, mathematics, handwriting, and enabling behaviors. Translation and reverse translation procedures were used to adapt the scale developed in English into Turkish. Expert opinion was sought for content validity. Test-retest correlation and item-total score correlation consistency measures were used to examine the psychometric properties of the Turkish form. Results demonstrated that the scale is a valid and reliable instrument to determine cognitive abilities in 24-36-month Turkish children. Infant and pre-school forms are recommended to be used for 3-47-months at every socio-cultural level.
TopCognitive development consists of perception, attention, concept, memory and recall, thinking and reasoning, problem solving and creativity, each of which develops and works in coordination with each other.
