Teknoloji çağında doğan ve büyüyen gençler, dijital
cihazları az bir çaba ile adeta uzman düzeyinde kullanabilmektedir. Öyle ki,
birden fazla medya cihazının eş zamanlı veya aralarında geçişler yapılarak
kullanımı olarak tanımlanan Çoklu medya görevi (ÇMG) davranışı özellikle
gençler tarafından sıklıkla gerçekleştirilmektedir. Teknoloji tüketimi günden
güne artış gösterirken, teknoloji kullanımının bilişsel düzeydeki sonuçları ile
ilgili çalışmalar da artış göstermektedir. Ancak bu çalışma sonuçları özellikle
çalışma belleği ve sürekli dikkat yetileri açısından karmaşık sonuçlar ortaya
koymaktadır. Mevcut araştırma ise, daha önce çalışılmamış olan Türk gençleri
örnekleminde çoklu medya davranışı ile sürekli dikkat ve çalışma belleği
performansları arasındaki ilişkiyi incelemeyi amaçlamıştır. Çalışmada çalışma
belleği ve sürekli dikkat yetilerini ölçmek için sırasıyla, Sayı menzili ve
Sürekli performans testi (SPT) görevleri kullanılmıştır. Sonuçlar, daha yüksek
ÇMG bildiriminin daha iyi çalışma belleği performansı ile ve daha kötü sürekli
dikkat performansı ile ilişkili olduğunu göstermiştir. Elde edilen bulgular,
kapasite ve çoklu kaynak teorileri ile nöroplastisite ışığında tartışılmıştır.

THE RELATIONSHIP BETWEEN MEDIA MULTITASKING, WORKING MEMORY AND SUSTAINED ATTENTION

Öz

Using
more than one device simultaneously is almost inevitable in our daily lives
because we face an overload of information and digital devices. As a result,
the effects of multitasking on working memory and sustained attention have
become a popular research topic in the literature, even if with inconsistent
results. The current study aims to examine the effects of media multitasking
behavior on sustained attention and working memory with a sample of Turkish
young adults. Continuous Performance Task (CPT) and Digit Span tasks were
employed for sustained attention and working memory, respectively. The results
showed that media multitasking correlated positively with digit span task
performance and negatively with the reaction time of false response in the CPT
task. That is to say, media multitasking may improve working memory performance
but inhibit maintaining attention. The results are discussed in the light of
theories of limited capacity, multiple resources, and neural plasticity.
