7Psycholinguistics : A brief history1900102050607080902000Pre-psycholinguistics (1800s):Philosophers of Language: Wittgenstein: underlying logic of language Russell: reference and language universals Frege: sense and reference (meaning)

psycINFO16Pre 192010Wundt suggesteed that the fundamental unit of language is the sentence -- not the word or the sound. He identified the sentence not just with a sequence of words and sounds, but as a special mental state. Sounds, words, the rules of grammer, etc., all have their meaning only in relation to that underlying mental sentence.

Wundt actually invented the tree diagram of syntax we are all familiar with in linguistics texts! Language starts with S (the sentence) at the top, and selective attention separates the subject (the focus or figure) from the predicate (the ground), and so on, in contrast to the popular bottom-up, associationistic conception the behaviorists proposed. Wundt's ideas are now the standard -- yet no one remembers they were his in the first place!

language processes = mental processesPsycholinguistics : A brief history1900102050607080902000Pre-psycholinguistics:Ferdinand de Saussure: Linguist Separation of historical linguistics and descriptive linguisticspsycINFO16Pre 1920

11Historical linguistics - comparing languages (primarily IndoEuropean languages) and discovering the principles guiding the changes undergone by the languages had been the dominant Descriptive linguistics - describing a language as a whole at a particular point in time

Psycholinguistics : A brief history1900102050607080902000Pre-psycholinguistics: From the 1920s to the mid 1950s Psychology was dominated by behaviorism John B. Watson (1920): Is thinking merely the action of language mechanisms? Leonard Bloomfield (1935): LanguagepsycINFO39901920-50

12Viewed language as systems of stimulus-response patterns (kind of verbal habits), built up through conditioningFocus of the behaviorist tradition is to only make theories about observable behaviors (basic argument: mental processes arent directly observable, so they arent testable, so they dont belong in theories)Psycholinguistics : A brief history1900102050607080902000Dawn of psycholinguistics (50s):Lashley (1951): Neuropsychologist Argued that the structure of a sentences must be more than just associations between adjacent words

psycINFO29111951-6014Psycholinguistics : A brief history1900102050607080902000Dawn of psycholinguistics (50s):1953: Another conference Included psychologists, linguists, anthropologists, and communication engineers First time the term psycholinguistics is used Birth of Cognitive Science

psycINFO29111951-6017Psycholinguistics : A brief history1900102050607080902000Dawn of psycholinguistics (50s):Noam Chomsky : Linguist (1957) published Syntactic Structures (1959) book review of Verbal Behavior

psycINFO29111951-6018Among the arguments, perhaps the most famous is his example:colorless green ideas sleep furiouslyEven though the associations between these words are virtually absent, the sentence is recognized as syntactically correct.In contrastfuriously sleep ideas green colorless is recognized as ungrammatical.Chomskyan revolutionMajor proposals/innovations Develop a grammar that can generate an infinite number of grammatical sentencesTransformational-generative grammarLanguage acquisition - innate universal grammarLimited explicit instruction for language learnersArguments against behaviorist accounts of languageOften credited with the downfall of behaviorism

Linguistics: linguists and psycholinguists are interested in common issues such as how do we parse sentence?, how do we recognize words?

Philosophy: interested in the philosophy of language such as the nature of meaning and reference, rational thinking, learning, reasoning, logic etc.

Computer science and speech technology: includes several disciplines that use computers, computer technology andcomputer software to discover what language is and does.

Neuroscience: is multidisciplinary science of the nervous system including medicine, psychology, psychiatry, biology, and brain imaging. It studies neurological aspects of language including language/spee
