Right = Left ? The concepts of “right-left” and brain asymmetrySag = Sol ? “Sag-sol” kavramlari ve beyin asimetrisi

SUMMARY

Although “right” and “left” are neutral words those describe directions, they have some positive and negative meanings in cultural contexts. Attributing positive meanings for right and negative meanings for left is observed in different cultures, languages and belief systems including Turkish culture. In the presented study, Turkish words, sayings and phrasses including right, left and right-left together were examined according to their meanings (positive, negative, neutral) by referencing Turkish Language Instituion. It was observed that the word “right” had 15 positive meanings and the word “left” had no positive meanings.  On the other hand, it was found that the word “right” had no negative meanings and “left” had four negative meanings and there were eight negative meanings including the words “left” and “right” together.  The predisposition of attributing positive/negative meanings to right and left is discussed in a neuroscientific perspective and it is assessed in the context of two hemispheric specializations in the brain: 1. Motor asymmetries and handedness 2. Emotions and Valence Hypothesis.  Generally, attributing positive meanings for right and negative meanings for left seems to be related to human physiological system, structural and functional brain asymmetries and dependently human cognition and comprehension. ÖzetSag ve sol kavramlari ilk anlamlari itibariyle yön belirten nötr sözcükler olmasina ragmen kültürel baglamda bu sözcüklerin olumlu ve olumsuz anlamlara sahip oldugu görülmektedir. Saga olumlu, sola olumsuz anlam atfetme Türk kültürü de dahil olmak üzere farkli kültürlerde, dillerde ve inanç sistemleri içerisinde gözlenmektedir. Sunulan makalede Türk Dil Kurumu referans alinarak sag, sol ve sag ile solun birlikte kullanildigi sözcük, birlesik sözcük, deyim ve atasözleri içerdikleri olumlu, olumsuz ve nötr anlamlara göre gruplandirilmistir. Buna göre Türk Dilinde “sag” sözcügüne iliskin 15 olumlu anlamin oldugu, buna karsin “sol” sözcügüne iliskin hiçbir olumlu anlamin olmadigi gözlenmistir. Öte yandan, “sag” sözcügüne iliskin hiçbir olumsuz anlamin olmadigi, “sol”sözcügüne iliskin dört ve “sol” ile “sagin” birlikte kullanildigi sekiz olumsuz anlamin oldugu bulunmustur. Sunulan makalede insanlarin saga ve sola olumlu/olumsuz anlam atfetme egilimi nörobilim bakis açisindan ele alinarak beyinde yer alan iki hemisferik özellesme temelinde degerlendirilmistir: 1. Motor Asimetriler ve El Kullanimi 2. Duygular ve Degerlik Hipotezi. Genel olarak saga olumlu, sola olumsuz anlamlar atfetmek insanin fizyolojik sistemiyle, yapisal ve islevsel beyin asimetrileriyle ve buna bagli olarak ortaya çikan insan bilisi ve kavrayisi ile ilgili gibi görünmektedir.
