Öz

Sağ ve sol beyin görünümü bakımından benzer olmasına karşın, işlevleri yönünden çeşitli özelleşmeler göstermektedir. Yetişkinlerle yapılan çok sayıdaki çalışma tipik olarak sol hemisferin sözel ve sayısal işlemlerde; sağ hemisferin ise yüz işleme ve görsel-uzamsal becerilerde uzmanlaştığını ortaya koymuştur. Öte yandan gelişmekte olan beyne sahip olan çocuklardaki hemisferik asimetrilerin yetiş-kinlerden bazı farklılıklar gösterebileceği düşünülmektedir. Bu nedenle sunulan makalede yetişkinlere göre daha az çalışılmış bir grup olan çocuklarda sol hemisferin özelleşme gösterdiği sözel ve sayısal işlemlere ve sağ hemisferin özelleşme gösterdiği yüz işleme ve görsel-uzamsal işlemlere ilişkin literatüre yer verilmiştir. Ayrıca çocuklarda iki hemisfer arasındaki etkileşiminin gelişimine dair çalışmalara değinilmiştir.
