Language Comprehension
Depends upon the integration of denotative Depends upon the integration of denotative meaning and the impact of syntaxmeaning and the impact of syntax
Semantic analysis requires considerable Semantic analysis requires considerable simultaneous processing of auditory and simultaneous processing of auditory and visual cuesvisual cues

Language Comprehension
Neural Correlations of Syntactic and Neural Correlations of Syntactic and Semantic Processing Semantic Processing Receptive auditory analysis depends Receptive auditory analysis depends
upon temporal region functions, upon temporal region functions, especially posterior functionsespecially posterior functions
Receptive reading requires more Receptive reading requires more integrated analysisintegrated analysis
Significant impairment in reading may Significant impairment in reading may reflect dyslexia reflect dyslexia
Language Comprehension
Neural Correlations of Syntactic and Neural Correlations of Syntactic and Semantic Processing Semantic Processing ERP studiesERP studies
Looks for EEG activation by syntax Looks for EEG activation by syntax or semantic violationsor semantic violations
Syntactical error yielded spike in Syntactical error yielded spike in central (S/M) region functionscentral (S/M) region functions
Semantic error yielded spike in Semantic error yielded spike in parietal region functions parietal region functions

Claims that syntax and semantic Claims that syntax and semantic analyses are processed by different analyses are processed by different processesprocesses
Language Comprehension

Language Comprehension
Examples of inferencesExamples of inferences Direct Direct
““The dentist pulled the tooth. The The dentist pulled the tooth. The patient liked the method.”patient liked the method.”
BackwardBackward““The tooth was pulled painlessly. The The tooth was pulled painlessly. The
dentist used a new method.” dentist used a new method.”
Language Comprehension
Examples of inferencesExamples of inferences ForwardForward
““The tooth was pulled painlessly. The The tooth was pulled painlessly. The patient liked the new method.”patient liked the new method.”
Forward inferences flow more readily to Forward inferences flow more readily to new materials, while backwards new materials, while backwards inferences are made in increase inferences are made in increase coherence, hence are more rapidcoherence, hence are more rapid
Language Comprehension
Language and Memory Language and Memory Loftus and Zanni (1975) nicely Loftus and Zanni (1975) nicely
demonstrated linguistic impact on demonstrated linguistic impact on memorymemory
““Did you see a broken headlight?”Did you see a broken headlight?”““Did you see the broken headlight?”Did you see the broken headlight?”
The later question elicited higher recall The later question elicited higher recall

Example:Example:• 1. “Tom shouted at Bill because he 1. “Tom shouted at Bill because he
spilled the coffee.”spilled the coffee.”• 2. “Tom shouted at Bill because 2. “Tom shouted at Bill because
he had a headache.”he had a headache.”
