When readers are asked to detect a target letter while reading for comprehension, they miss it more frequently when it is embedded in a frequent function word than in a less frequent content word. This missing-letter effect has been used to investigate the cognitive processes involved in reading. A similar effect, called the missing-phoneme effect…

Working memory allows us to hold specific pieces of information in an active and easily retrieved state, but what happens to that information during an unexpected interruption between study and test? To answer this question, we used a surprise trial paradigm in which an unexpected event precedes a probe of the observer's memory for a search…

Previous research in alphabetic languages has shown that both position (external, internal) and distance (adjacent, nonadjacent) modulate letter position encoding during reading. To examine the generality of this pattern for a comprehensive model of word recognition and reading, we examined these effects during Chinese reading (i.e., an unspaced…

Numerous studies have provided evidence that readers generate phonological codes while reading. However, a central question in much of this research has been how early these codes are generated. Answering this question has implications for the roles that phonological coding might play for skilled readers, especially whether phonological codes…

In Simon-type interference tasks, participants are asked to perform a 2-choice reaction on a stimulus dimension while ignoring the stimulus position. Commonly, robust congruency effects are found; that is, reactions are faster when the relevant stimulus attribute and the assigned response match the location of the stimulus. Simon congruency…

The present study utilized a novel methodological combination of eye tracking and postural movement recordings to study task-induced changes in cognitive engagement during expository text reading. Thirty-three participants read an expository text with a specific task in mind while their eye and postural movements were concurrently recorded, and…

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…

Stimuli that are fluently processed are more likely to be called "old" on a recognition memory test compared with less fluently processed stimuli. The goal of the current study was to investigate how the perceived diagnostic value of fluency is affected by a match between encoding and test conditions. During the encoding phase,…

Although previous research has shown that letter position information for the first letter of a parafoveal word is encoded less flexibly than internal word beginning letters (Johnson, Perea & Rayner, 2007; White et al., 2008), it is not clear how positional encoding operates over the initial trigram in English. This experiment explored the…

In 4 experiments, we used self-paced reading and eye tracking to demonstrate that readers are, under some conditions, sensitive to the presuppositions of definite versus indefinite determiner phrases (DPs). Reading was faster when the context stereotypically provided a single possible referent for a definite DP or multiple possible referents for…

Recent research has shown contextual diversity (i.e., the number of passages in which a given word appears) to be a reliable predictor of word processing difficulty. It has also been demonstrated that word-frequency has little or no effect on word recognition speed when accounting for contextual diversity in isolated word processing tasks. An…

A number of memory phenomena evident in recall in within-subject, mixed-lists designs are reduced or eliminated in between-subject, pure-list designs. The item-order account (McDaniel & Bugg, 2008) proposes that differential retention of order information might underlie this pattern. According to this account, order information may be encoded…

Additive and interactive effects of word frequency, stimulus quality, and semantic priming have been used to test theoretical claims about the cognitive architecture of word-reading processes. Additive effects among these factors have been taken as evidence for discrete-stage models of word reading. We present evidence from linear mixed-model…

Statements of the form if… then… can be used to communicate conditional speech acts such as tips and promises. Conditional promises require the speaker to have perceived control over the outcome event, whereas conditional tips do not. In an eye-tracking study, we examined whether readers are sensitive to information about perceived speaker control…

The present set of 7 experiments systematically examined the effectiveness of adding causal explanations to simple refutations in reducing or eliminating the impact of outdated information on subsequent comprehension. The addition of a single causal-explanation sentence to a refutation was sufficient to eliminate any measurable disruption in…
