1. Introduction Psycholinguistics = the study of language and mind mind versus brain • mind as understanding, senses, spirit, psyche • mind as total of cognitive capacities
Psycholinguistics is: study of language production & comprehension reflecting distinction of competence versus performance Psycholinguistics versus neighbor disciplines: Sociolinguistics, Neurolinguistics, Cognitive Linguistics
2. Biological foundations of speech 2.1 Organs of speech humans have no specific organs of speech, but we find specialization for speech in many parts of system
2.2 Nervous system central versus peripheral descending, versus ascending, motor sensory but both systems function together in complex activity, so that brain gets feedback on effects nerve development from birth to two years reflects growth in motor and language skills
special areas of brain for language skills organization of perception, language and articulation in the brain:
2.3 Brain Lateralization specialization of function in left and right hemispheres as part of evolutionary development in brain still, corpus callosum connects the two hemispheres
3. Linguistics and mental entities 3.1 Words and concepts • word meaning as mental image • words as signs of concepts, labels for concepts • concepts might be figures, images, models etc • concepts include perceptual and functional information
3.2 Sounds and phonemes phonemes as psychologically real entities abstract phoneme /p/ versus positionally variant allophones: • aspirated [ph] word-initial, as in pill • preglottalized [p] word-final, as in lip • unaspirated [p-]after initial s, as in spill
these allophones are predictable variants they don't distinguish meanings ability to distinguish meanings defines phonemes hence: minimal pair test pill - bill
but experiments show: words are recognized faster than phonemes we recognize the letter b and the sound /b/ faster in the word bat than in isolation words are more salient than phonemes suprasegmental features are also psychologically salient
intonation distinguishes statements and questions Sally's here. versus Sally's here? stress focuses on any constituent in questions Sally gave the new car to Judy today? • can question whether it was Sally (not Suzy), • whether she gave (not loaned) the car, • whether it was the new (not the old) car etc
3.4 Sapir-Whorf Hypothesis Sapir-Whorf Hypothesis sees language and human cognition as related in non-arbitrary ways Sapir 1921, 1929, 1949, Whorf 1950, 1956 proposed a relationship between language, meaning, culture, and personality, generally called the Sapir-Whorf Hypothesis
The strong version of the hypothesis says our language determines our perception. We see the things and processes our language has names for and ignore or cannot see what our language doesn't name. The weak version of the hypothesis says our language influences our perception. We attend to the things and processes our language has names for and tend to ignore or find it difficult to attend to what our language doesn't name.
Slobin's ‘thinking for speaking’ notes that any language system enforces certain choices in grammar and lexis, no matter how our underlying thought patterns work,
Compare: I like it, mir gefällt es, mi piace, I'm cold, mich friert, mir ist kalt, isch hann kalt, j'ai froid If we must always attend to certain distinctions and ignore others, in speaking and thinking, shouldn't that influence the way we think?
4. Words in the Mental Lexicon Mental Lexicon versus dictionary • words accessible via sound, meaning, related words Mental Lexicon versus encyclopedia • Encyclopedia contains all kinds of knowledge, usually unnecessary for normal word use, e.g. for dog
4.1 Word Association Tests (WATs) Experiments show: we recognize concrete words like table faster than abstract words like trouble table chair faster, more consistent trouble bad lower, less consistent
WATs also show paradigmatic versus syntagmatic relations: • paradigmatic apple, pear, banana, plum • syntagmatic apple, red, juicy, eat in WATs: • adults respond paradigmatically: pillow bed • children respond syntagmatically: pillow soft
WATs show faster recognition after associated words: we recognize roof faster after house than after some unrelated word like apple so Lindsay & Norman (1972) postulate lexical networks
4.2 Tip-of-the-Tongue Phenomena Thinking on Tip-of-the-Tongue (TOT) phenomena begins with James (1890) James speaks of “a gap that is intensively active” in consciousness when we try to recall a forgotten name. Meringer and Mayer (1895), Fromkin (1973) kept personal catalogues of error types to gather natural data.
Brown and McNeill (1966) collected intuitions on remembering in diary studies, e.g. unable to recall the name of the street on which a relative lives, one of us thought of Congress and Corinth and Concord and then looked up the address and learned that it was Cornish.
Burke et al. (1991) write, “When a TOT occurs, a lexical node in a semantic system becomes activated, giving access to semantic information about the target word, but at least some phonological information remains inaccessible.” Subjects in the TOT state often report that a word related to the target comes repeatedly and involuntarily to mind, yielding ‘blockers’,‘interlopers’ or ‘persistent alternates’, e.g. sexton or sextet for sextant
Burke et al. (1991) identify a semantic system or network of nodes connecting concepts • the concept chastity is connected with “is a virtue,” “take a vow of” etc • the concept baker with “bake bread” “get up early” “sell cakes” “knead dough” etc
4.3 Discourse, frames, prototypes Cognitive linguists look at discourse contexts where words occur, e.g. if, for an item like roof, The house needs a new roof Then "house has a roof" is part of discourse frame Consider also frame effects: We saw an old house. The roof was in need of repair.
Consider typical collocations and metaphors: she has no roof over her head - for 'no house' we're finally under one roof - for 'in the same house‘ Moreover, Rosch and her co-workers have shown: • some properties are more salient than others • some members of a category are more typical
it may be impossible to define certain words without exemplification, e.g. colors, fruits, games etc instead of: "a fruit is the edible part of a plant etc" we find: "a fruit is like an apple, a peach or a banana" • word meanings and categories are generally not defined by features or propositions, but by prototypes
Testing for prototypes A. Ask subjects to identify the most typical bird:
Prototype Effects: prototype: A trout is a typical fish marginal: A tadpole is a kind of a fish non-member: Their daughter is a regular fish Note: real members don't fit here: *This trout is a regular fish
5. First Language Acquisition Natural acquisition with no special learning necessary critical period resulting from a combination of factors: • development of connections between nerve cells • myelination of nerve cells
lateralization of brain functions • dominance of left hemisphere • corresponding development of motor skills • general cognitive stages of development (Piaget)
5.1 Developmental sketch Age Language General (months) 9 babbling crawling 10 first words standing, recurrent, maintained

What the lady said? • counting: 1 2 3 4 5 6 20 14 fiveteen 16
Mean Length of Utterance (MLU) as standard measure of first language development as opposed to age
5.2 Natural order of acquisition: 5.2.1 "Why mama and papa?“ Jakobson's order for phoneme acquisition • in babbling, children produce all kinds of sounds and sound combinations; many children produce imitations after babbling • but around age 2, children narrow their sound repertory and begin to produce sounds of their language in fixed order
order reflects an attempt to create the clearest possible set of distinctions at any given point, within the given physiological limits • this order of acquisition also reveals parallel • between different languages • most salient distinction is between Vowels (V) and • Consonants (C)
Vowels are characteristically open and resonant: • the prototypical V is a • Consonants are characteristically closed and obstruent: • stops are prototypical Cs • the prototypical stop is p • the prototypical syllable is CV: maximizing the C-V distinction, a child's first syllable should be pa • given children's tendency to reduplication, • a child's first real word should be papa
after the Cs p and m , the child usually acquires t , then the third voiceless stop k and so on: • p m t k • child moves on to ever larger patterns with increasing numbers of distinctive features
5.2.2 Order of acquisition for syntax at first, kids produce: • one-word utterances with holistic meaning • two-word utterances with no fixed word order • three-word utterances without inflections • prepositions or other markers then they begin to acquire syntax
