Psycholinguistics investigates the cognitive processes underlying language comprehension, production, and acquisition — and the relationship between language and thought has been one of the most debated questions in cogn
ZD_1_10 — Automata Theory and Formal Languages
Automata theory studies abstract computational machines and the classes of languages they recognize, forming the mathematical backbone of computer science. The Chomsky hierarchy (1956–59) classifies formal languages into
ZD_3_11 — History of Programming Languages: From Machine Code to Modern Paradigms
The history of programming languages traces the evolution of formal notations for instructing computers — from the raw binary patterns of machine code and the mnemonic abbreviations of assembly language through the devel

ZG_5_04 — Writing System Reform: Simplified Chinese, Turkish Latin, Hangul
Writing system reforms — deliberate, planned changes to a language's script, orthography, or writing conventions — represent some of the most dramatic and consequential acts of language planning in history. Three landmar
