Abstract

The goal of this study was to obtain the event-related potentials (ERP) under one cognitive paradigm and to examine the relationships between the ERP components and the neuropsychological test (NPT) scores. The sample consisted of participants who had at least 12 years of education, were between 19-67 years of age, were free of reported psychiatric or neurological disorders, and were not or had not been under medication that affects cog-nitive processes. Principle component analysis with varimax rotation was used to examine the relations between the ERPs that were obtained under the oddball paradigm (OB) from the Fz, Cz and Pz electrode locations with the Stroop Test TBAC Version. Results: The ERP pattern that was obtained in this study was similar to those obtained with the standard paradigm of the literature. Such findings show that ERP components of the present study are the reliable components of the literature. The results further showed that there were selective relations between cognitive ERPs values and NPT scores. According to these findings, the early electrophysiological activity, as indexed by the ERP components, can be used as predictors of specific long-lasting cognitive processes of humans, as indexed by NPT scores.

Özet

Bu çalışmanın amacı, bir bilişsel paradigma altında elde edilen olay-ilişkili potansiyelleri (OİP) belirlemek ve bu bileşenlerle nöropsikolojik test (NPT) puanları arasındaki ilişkileri incelemektir. Çalışmada, en az 12 yıl eğitim düzeyinde eğitim görmüş olan, psikiyatrik ve nörolojik hastalık öyküsü bulunmayan ve bilişsel süreçleri etkileme potansiyeline sahip ilaçları geçmişte ve halen kullanmamış olan, 19-67 yaş aralığında 53 denek yer almıştır. Seyrek uyarıcı paradigması (SUP) altında Fz, Cz ve Pz elektrot lokasyonlarından kaydedilen OİP'ler ile Stroop Testi TBAG Formu'ndan elde edilen puanlar arasındaki ilişkileri incelemede temel bileşenler analizi kullanılmıştır. Çalışmada elde edilen tepki örüntüsü, literatürün standart paradigması altında elde edilenlerle benzeşmektedir. Söz konusu bulgular, mevcut çalışmada elde edilmiş olan OİP bileşenlerinin literatürün güvenilir tepkileri olduğunu göstermiştir. Analizlerden elde edilen genel sonuçlar ise, bilişsel OİPler ile NPTlerin birbirleriyle seçici olarak ilişkili olduğunu göstermiştir. Bulgular, elde edilen OİP bileşenleriyle temsil edilen erken elektrofizyolojik aktivitenin, insanlarda, uzun süreli ayırt edilmiş bilişsel süreçlerin yordanmasında kullanılabileceğini göstermiştir.
