Psycholinguistics is the study of the relationship between language, thought and psychology. It draws from the natural sciences, the social sciences and the cognitive sciences. Psycholinguists are typically well-versed in one or more of the three.
Psycholinguistics became an accepted academic field of inquiry between the 1970's and the 1980's. At this time, academia started to embrace the idea of interdisciplinary studies.
Noam Chomsky was among the first strong advocates of Psycholinguistics. He tied language to perception, politics and global economics. George Lakoff did similar work in his book "Women, Fire, and Dangerous Things: What Categories Reveal about the Mind."
Current scholars in the field include Steven Pinker, Trevor Harley, and Natalia Sciarini.
