ABSTRACT
 Objective: This study was conducted to investigate the impact of brain dominance on problem-solving skills and hopelessness in individuals with visual impairment as a special group. Material and Methods: This descriptive study was conducted on 100 visually impaired individuals who were members of a private association in Turkey and met the inclusion criteria. The study data were collected using a Personal Information Form, Brain Dominance Inventory, Problem Solving Inventory and Beck Hopelessness Scale. In analysing the data, the study used percentage, mean, and the Mann-Whitney U and Kruskal-Wallis tests. Results: The analysis of the study results indicated that 48% of the participants used their right brain, 50% used their left brain, and 2% of the participants used both. It was found that visually impaired individuals who used their left brain more actively had lower mean scores on feelings and expectations about the future, hopelessness and loss of motivation, which are the subscales of the Beck Hopelessness Scale, whereas the mean score of their problem-solving skills was higher (p>0.05). Conclusion: The results of the study revealed that visually impaired individuals used one of the brain hemispheres predominantly and the used hemisphere actively affected problem solving and hopelessness. Visually impaired individuals can be trained according to the brain hemispheres they are dominant to use both brain regions. If so, problem solving skills will also increase.It is important to recognise that identifying visually impaired individuals' dominant learning styles is a significant factor in enhancing their problem-solving, decision making, analytical thinking and systematic planning skills.

Keywords: Visually impaired individuals; brain dominance; problem-solving; hopelessness
ÖZET
 Amaç: Bu çalışma, özel bir grup olan görme engelli bireylerin beyin baskınlık durumlarının problem çözme becerileri ve umutsuzluk düzeylerine etkisinin incelenmesi amacıyla yapılmıştır. Gereç ve Yöntemler: Tanımlayıcı tipte yapılan araştırma Türkiye'de özel bir derneğe üye olan, çalışma ölçütlerine uyan 100 görme engelli bireyle yürütülmüştür. Verilerin toplanmasında Kişisel Bilgi Formu, Beyin Baskınlığı Envanteri, Problem Çözme Envanteri ve Beck Umutsuzluk Ölçeği kullanılmıştır. Verilerin değerlendirilmesinde, yüzdelik, ortanca, MannWhitney U ve Kruskal-Wallis testleri kullanılmıştır. Bulgular: Araştırma sonuçları incelendiğinde, sağ beynini kullananların oranı %48, sol beynini kullananların %50, hem sağ hem de sol beynini kullananların oranı ise %2 olarak tespit edilmiştir. Görme engelli bireylerde sol beynini daha aktif kullanan görme engelli bireylerin Beck Umutsuzluk Ölçeği'nin alt boyutları olan gelecekle ilgili duygu ve beklentiler, umutsuzluk düzeyleriyle motivasyon kaybı ortanca değerlerinin daha düşük, problem çözme becerileri ortanca değerinin ise daha yüksek olduğu belirlendi (p>0,05). Sonuç: Araştırma sonuçlarına göre görme engelli bireylerin, beyin yarı kürelerinden yalnızca birini kullandıkları, aktif kullanılan beyin bölgesinin problem çözme ve umutsuzluk düzeyi üzerine etkili olduğu belirlendi. Görme engelli bireylere, her 2 beyin bölgesini de kullanmak için beyin hemisferlerine göre eğitim verilebilir. Böyle bir durumda, problem çözme becerileri de artacaktır. Görme engelli bireylerin beyin bölümlerini baskın kullanma hususunda problem çözme, karar verme, analitik düşünme ve sistematik planlama becerilerini geliştirmede önemli bir faktör olduğunu kabul etmek önemlidir.

Anahtar Kelimeler: Görme engelli bireyler; beyin baskınlığı; problem çözme; umutsuzluk
