How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

Article
As we age, language reflects patterns of both stability and change. On the one hand, vocabulary and semantic abilities are largely stable across the adult lifespan, yet lexical retrieval is often slower and less successful (i.e., slower picture naming times, increased tip of the tongue incidents). Although the behavioral bases of these effects have...
Article
Full-text available
Speakers can refer to previously-mentioned words (e.g., the actor) using attenuated referring expressions such as pronouns (he), or elaborated referential forms such as repeating the original word (the actor). Predictability is theorized to influence form of reference during language production: More attenuated forms may be used to refer to more pr...
Article
Full-text available
We investigated how phonologically similar words are encoded and retrieved from memory during sentence processing across younger and older adults. Critical sentences included two phonologically similar or dissimilar noun phrases (henceforth NPs) followed by a pronoun. We examined brain activity time-locked to the onsets of the second NP, and the pr...

Language comprehension relies on encoding, storage, and retrieval of words for integration with incoming input. A fundamental question is what factors impede or facilitate this process. Previous research has shown a "modification effect": Modified words (e.g., the injured and dangerous bear, or, the bear that was injured and dangerous) are subseque...
Article
Full-text available
Aging is often associated with declines in language production. For example, compared to younger adults, older adults experience more tip-of-the-tongue (TOT) states, show decreased speed and accuracy in naming objects, and have more pauses and fillers in speech, all of which indicate age-related increases in retrieval difficulty. While prior work h...
Article
Full-text available
Everyday speech contains disfluencies, including unintentionally spoken words. What is the fate of the misspoken word in the comprehender's memory? In this study, we asked whether: (1) the gender of misspoken words lingers and affects how the intended word is perceived, and (2) whether and how lingering representations can cause interference during...
Conference Paper
Full-text available
Previous research has shown that modified noun phrases (henceforth NPs) are subsequently retrieved faster than unmodified NPs. This effect is often called the "semantic complexity effect". However, little is known about its mechanisms and underlying factors. In this study, we tested whether this effect is truly caused by the semantic information ad...
Article
Full-text available
The number of similar-sounding words that a target word has, or its Phonological Neighborhood Density (PND), has been shown to influence word production. However, reported results are sometimes inconsistent, with studies showing facilitation, inhibition, and null effects of phonological neighbors. These mixed results may be due to the influence of...
Article
As individuals age, they experience increased difficulties producing speech, especially with infrequent words. Older adults report that word retrieval difficulties frequently occur and are highly frustrating. However, little is known about how age affects the neural basis of language production. Moreover, age-related increases in brain activation a...
Article
Full-text available
We examined whether the position of modifiers in English influences how words are encoded and subsequently retrieved from memory. Compared with premodifiers, postmodifiers might confer more perceptual significance to the associated head nouns, are more consistent with the "given-before-new" information structure, and might also be easier to integra...
Article
Full-text available
We review previous research showing that representations formed during language processing are sometimes just “good enough” for the task at hand and propose the “online cognitive equilibrium” hypothesis as the driving force behind the formation of good-enough representations in language processing. Based on this view, we assume that the language co...
Article
Full-text available
The amount of information attached to a noun phrase (henceforth, NP) has been shown to enhance accessibility and increase pronominal reference in language production. However, both the effect of information quantity on the comprehension of ambiguous pronouns and the time course of any informativity effect have been left unexplored. In two eyetracki...
Article
Full-text available
Previous research has shown that viewing images of nature scenes can have a beneficial effect on memory, attention, and mood. In this study, we aimed to determine whether the preference of natural versus man-made scenes is driven by bottom-up processing of the low-level visual features of nature. We used participants' ratings of perceived naturalne...
Chapter
Full-text available
If a pause occurs in the middle of a sentence, is it attributable to prosodic structure, planning problems, or both? And if both prosodic representation and performance constraints conspire to cause a speaker to divide a sentence into two units, can the durational effects that result be parsed into those two different sources? In this chapter, we a...
Article
Full-text available
Previous research has shown that interacting with natural environments vs. more urban or built environments can have salubrious psychological effects, such as improvements in attention and memory. Even viewing pictures of nature vs. pictures of built environments can produce similar effects. A major question is: What is it about natural environment...
Article
Full-text available
The length of a noun phrase has been shown to influence choices such as syntactic role assignment (e.g., whether the noun phrase is realized as the subject or the object). But does length also affect the choice between different forms of referring expressions? Three experiments investigated the effect of antecedent length on the choice between pron...
