Final answer:
Speech segmentation is a complex cognitive process that even infants engage in, and it's not based on simple processes but rather on language regularities (option D) learned from the environment combined with innate biological predispositions.
Step-by-step explanation:
The question relates to the concept of speech segmentation, which is the process by which humans are able to perceive individual words in the continuous flow of speech. One claim that is NOT true of speech segmentation is D. Speech segmentation uses simple processes based on the regularities in language. While speech segmentation does rely on recognizing regularities, this process is complex and involves sophisticated cognitive abilities. From early on, even babies use the regularities in language to help with the segmentation process, and by around 8 months, they are able to use language cues to segment sounds into distinct words, demonstrating the complexity of the process.
Language development is a remarkable cognitive function where infants start learning language skills from a very early age, even before they can speak. Children acquire language through both innate biological predispositions and interactions with their environment, showing that both nature and nurture play a role in language acquisition. When considering the various theories and evidence regarding how children learn language, it is clear that the process is intricate, relying on both biology and learned behavior to develop proficiency in their native language.
