عمر عقلي

The pruning process is shown in this clip that was constructed from MRI scans of healthy children and teens. The time-lapse animation compresses 15 years of brain development (ages 5-20) into just a few seconds. Red indicates more gray matter, blue less gray matter. The changes in color from yellow/red to blue show the pruning process. (source: NIMH)

العمر العقلي يعني درجة ذكاء الفرد بالنسبة بالنسبة إلى الافراد في نفس سنه, فمثلا عندما نقول ان عمره العقلي 9 سنوات فيعني أنه يتجح في اختبارات الذكاء التي يجتازها طفل عمره 9 سنوات, والعمر العقلي يستخدم في قياس نسبة الذكاء IQ وذلك بقسمة العمر العقلي على العمر الزمني وضرب الناتج في 100

The limitations of the Standford-Binet caused David Wechsler to publish the Wechsler Adult Intelligence Scale (WAIS) in 1955. These two test were split into two different ones for children. The WAIS-IV is the known current publication of the test for adults. The reason for this test was to score the individual and compare it to others of the same age group rather than to score by chronological age and mental age. The fixed average is 100 and the normal range is between 85 and 115. This is a standard currently used and is used in the Stanford-Binet test as well.
