PSY 369: Psycholinguistics Language Comprehension: Methods for sentence comprehension
Other Relevant Findings? • Bias towards “well-formed” stimuli • Misidentify words with uncommon spelling patterns • BOUT as BOAT • misidentify nonwords (e.g., SALID) as words that are like it (SALAD). • Difficulty identifying nonwords with irregular spelling patterns (e.g., ITPR) more than those with regular spelling patterns (e.g., PIRT).
Sublexical units • Sublexical units bigger than phonemes and graphemes? • onsets and rimes • onset: initial consonant or consonant cluster in a word or syllable • rime: following vowel and consonants • if words broken at onset-rime boundary, resulting letter clusters more easily recognized as belonging together than if broken at other points • example: FL OST ANK TR vs. FLA ST NK TRO
Adding a bigram level By adding a frequency-sensitive bigram level, we can account for the findings of well-formedness along with the others.
Summing up • Word recognition is based on a feature-detector system • Biased to perceive common or recently occurring features
Studying Word Identification • Generally people ask: what makes word identification easy or difficult? • The assumption: • Time spent identifying a word can be a measure of difficulty • Measures of identification time are usually indirect
Some Identification Time Measures • Measure how long people take to say a string of letters is (or is not) a word (lexical decision) • Measure how long people take to categorise a word (“apple” is a fruit) • Measure how long people take to start saying a word (naming or pronunciation time) • Measure how long people actually spend looking at a word when READING • Line by line reading • Word by word reading • using eye movement monitoring techniques
Line-by-line A banker is a fellow
Line-by-line who lends you his umbrella
Line-by-line when the sun is shining
Line-by-line but wants it back
Line-by-line the minute it begins to rain.
Line-by-line • Problem: • Overall reading time for entire sentence or phrase • need for more “on-line” measurements • Timing on a smaller scope • See effects at level of word
Word-by-word • RSVP (rapid serial visual presentation)

Word-by-word • A couple of methods • RSVP (rapid serial visual presentation) • Moving window • Better, more “on-line” • But, these measures are also a little bit unnatural (especially RSVP) • e.g., Don’t allow regressions (looking back)
