Introduction

• human language is probably one of the most
  complex processes to be found anywhere on our
  planet
• productivity of language
• psycholinguistics

3
The Nature of Language

• phoneme
• morpheme
• morphology
• syntax
• grammar
• semantics
• pragmatics

4
The Nature of Language

• Background on the Structure of Language
• phrase structure
• constituents
• nouns
• verbs
• working memory

6
The Nature of Language

• A Brief History of Psycholinguistics
• Chomsky's Approach
• language abilities explained in terms of a
  complex system of rules and principles
  represented in the minds of speakers
• humans have innate language skills
• language is modular (language is special, not
  processed the same as other cognitive tasks)
• surface structure vs. deep structure of sentences
• ambiguous sentences

7
The Nature of Language

• A Brief History of Psycholinguistics
• Reactions to Chomsky's Theory
• early enthusiasm and later revisions
• research failed to support the prediction that
  people would take longer to process sentences
  requiring numerous transformations
• later theories provided constraints on language
  learner's inborn knowledge
• information conveyed in individual words

8
The Nature of Language

• A Brief History of Psycholinguistics
• Psycholinguistic Theories Emphasizing Meaning
• emphasis on human mind rather than on structure
  of language
• semantics

9
The Nature of Language

• A Brief History of Psycholinguistics
• Psycholinguistic Theories Emphasizing Meaning
• Cognitive-Functional Approach (usage-based
  linguistics)Tomasello
• the function of human language in everyday life
  is to communicate meaning to other individuals
• cognitive processes intertwined with language
  comprehension and production
• children use flexible strategies to create
  increasingly complex language
• adults use language strategically

10
The Nature of Language

• Factors Affecting Comprehension
• Negatives
• negative statements require more processing time
  than affirmative statements
• affirmative statements produce fewer errors
• The Passive Voice
• active form of a sentence is easier to understand
  than the passive form
• Nested Structures
• can result in memory overload

11
The Nature of Language

• Factors Affecting Comprehension
• Ambiguity
• Ambiguous Words
• people pause longer when they are processing an
  ambiguous word
• when people encounter a potential ambiguity, the
  activation builds up for all the well-known
  meanings of the ambiguous item

12

• And some communications are just hard to
  understand
• YouTube - The missile knows where it is
  (portfolio length)

13
The Nature of Language

• Factors Affecting Comprehension
• Ambiguity
• Ambiguous Words
• People are likely to choose one particular
  meaning
• 1. if that meaning is more common than the
  alternate meaning
• 2. if the rest of the sentence is consistent with
  that meaning

14
The Nature of Language

• Factors Affecting Comprehension
• Ambiguity
• Ambiguous Sentence Structure
• wandering down the wrong path
• we can usually understand ambiguous language, but
  we respond more quickly and more accurately when
  the language is straightforward
• Ambiguous headlines

15
The Nature of Language

• In Depth Neurolinguistics
• Neurolinguistics
• Individuals with Aphasia
• aphasia
• Broca's area/Broca's aphasiaexpressive-language
  deficit
• Wernicke's area/Wernicke's aphasiareceptive-langu
  age deficit
• both kinds of aphasia can decrease grammatical
  accuracy

17
The Nature of Language

• In Depth Neurolinguistics
• Hemispheric Specialization
• lateralization
• the left-hemisphere's role in language
• the right-hemisphere's role in language
• the hemispheres working together

18
The Nature of Language

• In Depth Neurolinguistics
• Neuroimaging Research with Normal Individuals
• functional magnetic resonance imaging (fMRI)
• left temporal lobe
• Gernsbacher and Robertson (2005)"A"/"The" study
• virtually identical patterns of activation in
  left hemisphere
• right hemisphere response differently to
  connected language ("the" sentences) than to
  disconnected language ("a" sentences)

19
Basic Reading Processes

• Reading requires virtually every cognitive
  process
• Reading is remarkably efficient and accurate
• Many challenges including (in English) irregular
  pronunciations due to lack of one-to-one
  correspondence between alphabet and speech sounds
  (phonemes)

20
Basic Reading Processes

• Discovering the Meaning of Unfamiliar Words
• Context
• perceiving familiar words
• resolving the meaning of ambiguous words
• discovering the meaning of unfamiliar words

21
Basic Reading Processes

• Discovering the Meaning of Unfamiliar Words
• Sternberg and Powell (1983)
• context can provide several kinds of information
  cues about the meaning of an unknown word (e.g.,
  when and where an unknown item occurs)
• words that appear in a rich context of different
  cues are more likely to be accurately defined

22
Basic Reading Processes

• Discovering the Meaning of Unfamiliar Words
• Sternberg and Powell (1983) (continued)
• large individual differences
• ability to use contextual cues and provide
  accurate definitions for unfamiliar words
  correlated with tests of vocabulary, reading
  comprehension, and general intelligence

23
Basic Reading Processes

• Reading and Working Memory
• readers who have a relatively large
  working-memory span can quickly process ambiguous
  sentences
• people with large working-memory spans are
  especially skilled in reading difficult passages
  and solving complex verbal problems
• working memory helps us to understand complicated
  sentences

24
Basic Reading Processes

• Two Pathways for Reading Words
• How do we look at a pattern of letters and
  actually recognize that word?
• Dual-route approach to readingskilled readers
  employ both a direct-access route (recognize word
  directly through vision) and an indirect-access
  route (recognize word by first sounding out the
  word)

25
Basic Reading Processes

• Two Pathways for Reading Words
• Research on the Dual-Route Approach
• Bradshaw and Nettleton (1974)direct-access
  approach
• pairs of words with similar spelling, but
  different sounds
• read first word silently and then pronounce
  second word out loud
• no interference indicated by no hesitation in
  pronouncing second word
• suggests that we do not silently pronounce each
  word during normal reading

26
Basic Reading Processes

• Two Pathways for Reading Words
• Research on the Dual-Route Approach
• Luo and coauthors (1998)indirect-access approach
• pairs of words judged related or unrelated in
  meaning
• students made errors on pairs where the second
  word sounds like a word that is semantically
  related to the first word (e.g., LION-BARE)
• suggests they were silently pronouncing the word
  pairs when they made the judgments
• few errors on pairs where the second word looked
  like a related word (e.g., LION-BEAN)

27
Basic Reading Processes

• Two Pathways for Reading Words
• Research on the Dual-Route Approach
• Word sounds may be especially important when
  children begin to read. Children with high
  phonological awareness have superior reading
  skills.
• Children vs. adultstongue twisters

28
Basic Reading Processes

• Two Pathways for Reading Words
• Research on the Dual-Route Approach
• Dual-route Approach
• flexible
• argues that the characteristics of the reading
  material determine whether access is indirect or
  direct
• argues that characteristics of the reader also
  determine whether access is indirect or direct
• individual differences

29
Basic Reading Processes

• Two Pathways for Reading Words
• Implications for Teaching Reading to Children
• Whole-word approach (direct access)
• argues readers can directly connect the written
  wordas an entire unitwith the meaning that this
  word represents
• argues that children should not learn to
  emphasize the way a word sounds
• emphasizes context within a sentences
• problemeven skilled adult readers achieve only
  about 25 accuracy when they look at an
  incomplete sentence and guess which word is
  missing

30
Basic Reading Processes

• Two Pathways for Reading Words
• Implications for Teaching Reading to Children
• Phonics approach (indirect access)
• readers recognize words by trying to pronounce
  the individual letters in the word
• "sound it out"
• argues that speech sound is a necessary
  intermediate step in reading
• emphasizes developing children's awareness of
  phonemes
• phonics training helps children who have reading
  problems

31
Basic Reading Processes

• Two Pathways for Reading Words
• Implications for Teaching Reading to Children
• Most educators and researchers support some sort
  of compromise
• Whole-language approachreading instruction
  should emphasize meaning, and it should be
  enjoyable, to increase children's enthusiasm
  about learning to read.
• The issue of basic literacy
