Humans have an innate understanding of the abstract principles of language. Language learning involves the more superficial characteristics of a particular language. Language is modular (language is special, not processed the same as other cognitive tasks). surface structure vs. deep structure of sentences transformational rules ambiguous sentences Reactions to Chomsky's Theory early enthusiasm and later revisions transformations universal patterns Recent theories propose that young language learners make only a limited number of hypotheses about the structure of their language. Information is conveyed in individual words. ©2013 John Wiley & Sons, Inc. Margaret W. Matlin, Cognition, 8e Outline Chapter 9 Page 3 of 14 A Brief History of Psycholinguistics (continued) Psycholinguistic Theories that Emphasize Meaning emphasis on human mind and semantics, rather than on the grammatical aspects of language cognitive-functional approach—Tomasello The function of human language in everyday life is to communicate meaning to other individuals. Cognitive processes are intertwined with language comprehension and production. Children use flexible strategies to create increasingly complex language. Adults use language strategically. Demonstration 9.2; different perspectives on the same event People can use language creatively. Factors Affecting Comprehension Negatives Clark & Chase (1972) Negative statements require more processing time than affirmative statements. Affirmative statements produce fewer errors. Multiple negatives decrease performance. The Passive Voice Ferreira and her coauthors (2002) sentence plausibility The active form of a sentence is easier to understand than the passive form. Complex Syntax difficult to understand can result in memory overload nested structure working memory ©2013 John Wiley & Sons, Inc. Margaret W. Matlin, Cognition, 8e Outline Chapter 9 Page 4 of 14 Factors Affecting Comprehension (continued) 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. 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 Ambiguous Sentences wandering down the wrong path especially difficult when initial interpretation is confirmed by long string of words before error becomes apparent We can usually understand ambiguous or complicated language, but we respond more quickly and more accurately when language is straightforward. The "Good-Enough" Approach to Language Comprehension People typically manage to read quite rapidly. The good-enough approach—Ferreira and colleagues People frequently process only part of a sentence. People usually do not work hard to create the most accurate, detailed interpretation of every sentence they read or hear. People read quickly, and they try to grasp the general meaning of a sentence. Knowledge of language typically leads to an accurate interpretation. This strategy can sometimes lead to errors in language comprehension. ©2013 John Wiley & Sons, Inc. Margaret W. Matlin, Cognition, 8e Outline Chapter 9 Page 5 of 14 In Depth: Neurolinguistics neurolinguistics The neurological basis of language is very complicated. Individuals with Aphasia aphasia Figure 9.1: Broca's Area & Wernicke's Area Broca's area/Broca's aphasia—expressive-language deficit Wernicke's area/Wernicke's aphasia—receptive-language deficit People with Broca's aphasia may also have some trouble with language comprehension. Many people with Wernicke's aphasia have problems with language production as well as language comprehension. The two kinds of aphasia are more similar than researchers once believed. Some difficulties are only revealed when speakers of particular languages are studied. Hemispheric Specialization lateralization variations related to handedness Role in language left hemisphere speech perception/sound interpretation meaning imagery right hemisphere emotional tone humor more abstract language tasks The hemispheres work together: interpreting subtle word meanings resolving ambiguities combining the meaning of several sentences ©2013 John Wiley & Sons, Inc.

Matlin, Cognition, 8e Outline Chapter 9 Page 6 of 14 In Depth: Neurolinguistics (continued) Neuroimaging Research in Adults Without Aphasia functional magnetic resonance imaging (fMRI) detects change that occur very quickly safer than PET scan inaccurate when participants move their heads even slightly better for language comprehension than language production 1. Using the fMRI method to study language in the left hemisphere. Kanwisher and colleagues attempts to identify specific areas responsible for language comprehension tasks individual differences language-localizer task compensates for individual differences creates linguistic map for each person using complex language tasks later, test each person on language and non-language tasks Specific regions of left frontal lobe responded only to language tasks, but not to other kinds of cognitive tasks. Other research has located portions of the left hemisphere that process specific linguistic information (e.g., sentences vs. non-words). 2. Using the fMRI method to study language in the right hemisphere. Demonstration 9.4: Reading Two Sets of Sentences Gernsbacher and Robertson (2005)—"A"/"The" study virtually identical patterns of activation in left hemisphere right hemisphere responded differently to connected language ("The" sentences) than to disconnected language ("A" sentences) ©2013 John Wiley & Sons, Inc. Margaret W. Matlin, Cognition, 8e Outline Chapter 9 Page 7 of 14 In Depth: Neurolinguistics (continued) How the Mirror System Can Facilitate Communication mirror system—a network of neurons in the brain’s motor cortex that are activated when you watch someone perform an action Rizzolatti and colleagues measure responses of single neurons monkeys watching a researcher break open a peanut Monkeys' responses while watching were similar to when the monkeys themselves broke open a peanut. Calvo-Merino and colleagues (2005) fMRI data for experts in classical ballet or martial arts videos of classical ballet vs. videos of martial arts fMRIs for experts in classical ballet showed significantly greater activation in the motor-cortex areas relevant to ballet movements, and relatively little activation in the areas relevant to martial arts. Individuals who were experts in martial arts showed the reverse activation pattern. In other words, experts can grasp meaning by watching another person, when they have fully developed the appropriate motor ‘‘vocabulary.’’ Language is not limited to spoken and written messages; physical actions also important. Sound-based language is not the only way people communicate. Mirror neurons may be especially active when we try to listen to someone talking in a noisy setting—a setting where we really need assistance. Apparently, we can also comprehend messages from the actions of other people. ©2013 John Wiley & Sons, Inc. Margaret W. Matlin, Cognition, 8e Outline Chapter 9 Page 8 of 14 BASIC READING PROCESSES Reading requires virtually every cognitive process. Reading is remarkably efficient and accurate. Demonstration 9.5: Many challenges (in English) are due to irregular pronunciations, i.e., lack of one-to-one correspondence between alphabet and speech sounds (phonemes). Comparing Written and Spoken Language 1. Reading is visual and is spread out across space, whereas speech is auditory and is spread out across time. 2. Readers can control the rate of input, whereas listeners usually cannot. 3. Readers can re-scan the written input, whereas listeners must rely much more heavily on their working memory. 4. Readers usually encounter standardized, error free input, whereas listeners often need to cope with variability, grammatical errors, sloppy pronunciation, and interfering stimuli. 5. Readers can see discrete boundaries between words, whereas listeners often encounter unclear boundaries in spoken language. 6. Readers encounter only the stimuli on a page, whereas listeners encounter both nonverbal cues and auditory cues, such as emphasized words and variations in pace. 7. Children require elaborate teaching to master some written languages—such as written English—but they learn spoken languages much more easily. 8. Adult readers typically learn new words more quickly when they appear in a written form, rather than a spoken form. Both written and spoken language require us to understand words and appreciate the meaning of sentences. For adults, scores on reading comprehension tests are highly correlated with scores on oral comprehension tests. ©2013 John Wiley & Sons, Inc. Margaret W. Matlin, Cognition, 8e Outline Chapter 9 Page 9 of 14 Reading Words: Theoretical Approaches How do we look at a pattern of letters and actually recognize that word? dual-route approach to reading—skilled readers employ both a directaccess route (recognize word directly through vision) and an indirectaccess route (recognize word by first sounding out the word) The Direct-Access Route Bradshaw and Nettleton (1974) pairs of words with similar spelling, but different sounds first word read silently, second word pronounced out loud no interference indicated by no hesitation in pronouncing second word Results suggest that people do not silently pronounce each word during normal reading. The Indirect-Access Route People often translate visual stimuli into sound during reading. Sound coding may enhance working memory. Luo and coauthors (1998) pairs of words judged as 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) Word sounds may be especially important when children begin to read. Children with high phonological awareness have superior reading skills. children vs. adults—tongue twisters (Demonstration 9.6) 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 (e.g., beginning vs. advanced readers; poor vs. good readers) consistent with brain-imaging research ©2013 John Wiley & Sons, Inc. Margaret W. Matlin, Cognition, 8e Outline Chapter 9 Page 10 of 14 Implications for Teaching Reading to Children Language predictability and reading-accuracy scores—less predictable languages associated with lower reading-accuracy scores in children Whole-word approach (direct access) argues readers can directly connect the written word—as an entire unit—with the meaning that this word represents argues that children should not learn to emphasize the way a word sounds emphasizes context within a sentences problem—Even skilled adult readers achieve only about 25% accuracy when they look at an incomplete sentence and guess which word is missing. 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. Most educators and researchers support some sort of compromise. Whole-language approach Reading instruction should emphasize meaning. Reading instruction should be enjoyable, to increase children's enthusiasm about learning to read. Other issues Children need to have books they can read outside of school. reading and social awareness the importance of basic literacy ©2013 John Wiley & Sons, Inc. Margaret W. Matlin, Cognition, 8e Outline Chapter 9 Page 11 of 14 UNDERSTANDING DISCOURSE discourse—interrelated language units larger than a sentence Frederick Bartlett's research—People’s recall of stories becomes more consistent with their schemas after a long delay. importance of context, general background knowledge, expertise, scripts, and schemas interaction of bottom-up and top-down processing inferences Forming an Integrated Representation of the Text How do we gather information together and remember the various concepts to form an cohesive and memorable message? theory of mind—In everyday life, people try to figure out the mental state of other people in their lives. Skilled readers frequently organize and integrate information into a cohesive story (e.g., "A" vs. "The" in Demonstration 9.4). mental models during reading (e.g., mental map of locations described in writing) construct internal representations (e.g., characters in a story) make inferences going beyond the information given ©2013 John Wiley & Sons, Inc. Margaret W. Matlin, Cognition, 8e Outline Chapter 9 Page 12 of 14 Drawing Inferences During Reading inference during reading—People draw on world knowledge in order to access information that is not explicitly stated in a written passage. People combine the information they are reading, together with the information presented in a passage. Then they draw a reasonable conclusion based on that combination. Consistent with Theme 1, people are active information processors. The Constructionist View of Inferences Readers usually draw inferences about the causes of events and the relationships between events. Readers actively integrate current information with all the relevant information from previous parts of the text, as well as background knowledge. Huitema and coauthors (1993) brief story (e.g., Demonstration 9.7) far/near placement of test sentence from statement of goal consistent/inconsistent relationship between goal and test sentence measure reading time for test sentence reading time longer for inconsistent statements Readers try to connect material within a text passage; consult information stored in long-term memory; try to construct an internally consistent representation. Other research—Readers create causal inferences in order to integrate discourse and construct a well-organized story. Factors That Encourage Inferences working-memory capacity metacomprehension skills expertise scientific texts Higher-Level Inferences Some genres of books activate different expectations. Inferences may be based on how the reader wants the story to turn out. Mental preferences for a particular outcome may interfere with judgments about how the story actually turned out. ©2013 John Wiley & Sons, Inc. Margaret W.

People who were highly anxious tended to report poorer study skills. Study skills were not strongly correlated with scores on the multiple-choice test. People with high scores on the Cognitive Test Anxiety scale also made more errors in summarizing textbook material and more errors on a test of ability to make correct inferences. ©2013 John Wiley & Sons, Inc.
