İçsel Konuşma Sıklığına Göre Bilişsel ve Fizyolojik Stres Tepkilerinin Karşılaştırılması

Abstract

İçsel konuşmanın sıklığı ve buna duyulan ihtiyaç kişiler arası farklılılar göstermekle birlikte içsel konuşma sıklığı, duygu düzenleme ve dürtü kontrol süreçleriyle ilişkili görülmektedir. Bu çalışma, içsel konuşma (İK) sıklığının bireylerin duygu düzenlemesi, dürtüsel davranışları ve fizyolojik stres tepkileri ile ilişkisini incelemiştir. Örneklem, 18–39 yaş aralığında ikinci dili İngilizce olan 35 üniversite öğrencisinden oluşmaktadır. Katılımcılar içsel konuşma sıklığını ölçen VISQ (varieties of inner speech questionaire) anketinden alınan puana göre yüksek ve düşük içsel konuşma olmak üzere iki gruba ayrılmıştır. Bu çalışma Duygu düzenleme ölçeği (ERQ) ve Dürtüsel Davranış Ölçeği (UPPS) puanlarının yüksek ve düşük içsel konuşma grupları arasında farklılaşacağı; stres koşulu ile dinlenim koşulu karşılaştırıldığında düşük ve yüksek içsel konuşma grubunun fizyolojik tepkilerinin (deri iletkenliği yanıtı ve kalp ritmi (HR)) farklılaşacağı hipotezini araştırmaktadır. Stres koşulu, zaman limitli Stroop ve zihinsel aritmetik görevleriyle oluşturulmuştur ve fizyolojik tepkiler BIOPAC® MP36 sistemi kullanılarak kaydedilmiştir. Gruplar arası (İK düşük-İK yüksek) analizler bağımsız örneklemler t-testi ile, grup içi analizler (baseline SCL, HR- görev SCL, HR) ise tekrarlı ölçümlü ANOVA ile gerçekleştirilmiştir. Bulgular, duygu düzenleme ölçeği ve dürtüsellik ölçeği puanlarında gruplar arasında (düşük ve yüksek içsel konuşma) anlamlı bir fark olmadığını göstermiştir. Deri iletkenliği düzeyi (SCL) ve HR tepkileri zihinsel aritmetik görevi boyunca dinlenim durumuna göre anlamlı biçimde artmış ve zaman limitli Stroop görevindeki tepki süreleri ve doğruluk oranlarında ise anlamlı farklılık bulunmamıştır. SCL veya HR tepkilerinde gruplar arasında (düşük ve yüksek içsel konuşma) anlamlı bir fark gözlenmemiştir. Bu sonuçlara göre, zihinsel artimetik görev ile oluşturulmuş stres koşulunda fizyolojik stres tepkileri oluşmasına karşın, içsel konuşma sıklığının strese verilen emosyonel veya fizyolojik tepkiler üzerinde anlamlı bir etkisi olmadığını göstermektedir. İçsel konuşma sıklığının yüksek ve düşük olarak belirlenmesinde kullanılacak ölçeği dikkate alarak, gelecek çalışmaların örneklem büyüklüğü ve görev sırası etkileri gibi faktörleri ele alması gerekmektedir.

The Role of Inner Speech in Modulating Electrophysiological Stress Responses

Abstract

The frequency and reliance on inner speech (IS) vary across individuals and may influence self-regulation processes such as emotion regulation and impulse control. This study examined whether IS frequency is associated with differences in emotion regulation, impulsive behavior, and physiological stress responses. The sample consisted of 35 university students aged 18–39 who completed self-report measures and were categorized into high and low IS groups based on the Varieties of Inner Speech Questionnaire (VISQ-R). Emotion regulation (ERQ), impulsive behavior (UPPS), and cognitive status (MMSE) were also assessed. Stress was induced through Stroop and mental arithmetic tasks, and physiological responses, skin conductance level (SCL) and heart rate (HR), were recorded during baseline and task phases using the BIOPAC® MP36 system. It was hypothesized that IS frequency would differentiate self-report measures as well as HR and SCL responses, reflecting variations in autonomic nervous system activity. Between-group comparisons were conducted using independent samples t-tests, and within-group changes were assessed using repeated-measures ANOVA. Results showed no significant group differences in emotion regulation or impulsivity. Although SCL and HR increased significantly during the task phases, indicating successful stress induction, no IS-related differences were found in physiological responses, reaction times, or accuracy on Stroop tasks. These findings suggest that while the stress manipulation was effective, IS frequency did not substantially affect cognitive or physiological outcomes. Future research should consider larger sample sizes and counterbalancing task order.
