SPEECH – A PSYCHOPHYSIOLOGICAL AND INTELLECTUAL PHENOMENON

This article analyzes psychophysiological and intellectual speech aspects emphasizing its complex nature, and also a key role in a human being. Speech is presented not only as means of information transmission, but also, as a dynamic phenomenon deeply rooted in different processes as cognitive, emotional, and social. The authors research how speech functions as a link between individual mechanisms and social context, showing the important role in communication and personal identity. Special attention is given to the neurophysiological basis, including the brain structures and the other processes which are responsible for language perception and speech articulation. Based on current research in such disciplines as neuroscience, psychology, and linguistics, the authors indicate that speech brain activity reflects a wide range of higher cognitive abilities like reasoning, decision-making, and emotional regulation. In addition, the role of speechin intellectual development is tested: how it contributes to learning, abstract concepts formation and critical thinking ability. The relationship between language and thinking is analyzed from psychological and philosophical points of view, and the thesis is put forward that language not only expresses ideas, but also shapes the perception of reality. The social and cultural aspects of speech are also being researched, including its importance for self-expression, interpersonal communication, and the transmission of collective knowledge, and cultural values. The article offers new scientific approaches for understanding the speech nature, and emphasizes its integrative role, uniting biological, mental, and social aspects of human existence, as well as itsimportance as a driving force in the civilization development.
