Word features in parafoveal vision influence eye movements during reading. The question of whether readers extract semantic information from parafoveal words was studied in 3 experiments by using a gaze-contingent display change technique. Subjects read German sentences containing 1 of several preview words that were replaced by a target word during the saccade to the preview (boundary paradigm). In the 1st experiment the preview word was semantically related or unrelated to the target. Fixation durations on the target were shorter for semantically related than unrelated previews, consistent with a semantic preview benefit. In the 2nd experiment, half the sentences were presented following the rules of German spelling (i.e., previews and targets were printed with an initial capital letter), and the other half were presented completely in lowercase. A semantic preview benefit was obtained under both conditions. In the 3rd experiment, we introduced 2 further preview conditions, an identical word and a pronounceable nonword, while also manipulating the text contrast. Whereas the contrast had negligible effects, fixation durations on the target were reliably different for all 4 types of preview. Semantic preview benefits were greater for pretarget fixations closer to the boundary (large preview space) and, although not as consistently, for long pretarget fixation durations (long preview time). The results constrain theoretical proposals about eye movement control in reading. (PsycINFO Database Record (c) 2013 APA, all rights reserved).

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 eye-movement experiment was conducted wherein the effects of word-frequency and contextual diversity were directly contrasted in a normal sentence reading scenario. Subjects read sentences with embedded target words that varied in word-frequency and contextual diversity. All 1st-pass and later reading times were significantly longer for words with lower contextual diversity compared to words with higher contextual diversity when controlling for word-frequency and other important lexical properties. Furthermore, there was no difference in reading times for higher frequency and lower frequency words when controlling for contextual diversity. The results confirm prior findings regarding contextual diversity and word-frequency effects and demonstrate that contextual diversity is a more accurate predictor of word processing speed than word-frequency within a normal reading task.

Although a group of people working together remembers more than any one individual, they recall less than their predicted potential. This finding is known as collaborative inhibition and is generally thought to arise due to retrieval disruption. However, there is growing evidence that is inconsistent with the retrieval disruption account, suggesting that additional mechanisms also contribute to collaborative inhibition. In the current studies, we examined 2 alternate mechanisms: retrieval inhibition and retrieval blocking. To identify the contributions of retrieval disruption, retrieval inhibition, and retrieval blocking, we tested how collaborative recall of entirely unshared information influences subsequent individual recall and individual recognition memory. If collaborative inhibition is due solely to retrieval disruption, then there should be a release from the negative effects of collaboration on subsequent individual recall and recognition tests. If it is due to retrieval inhibition, then the negative effects of collaboration should persist on both individual recall and recognition memory tests. Finally, if it is due to retrieval blocking, then the impairment should persist on subsequent individual free recall, but not recognition, tests. Novel to the current study, results suggest that retrieval inhibition plays a role in the collaborative inhibition effect. The negative effects of collaboration persisted on a subsequent, always-individual, free-recall test (Experiment 1) and also on a subsequent, always-individual, recognition test (Experiment 2). However, consistent with the retrieval disruption account, this deficit was attenuated (Experiment 1). Together, these results suggest that, in addition to retrieval disruption, multiple mechanisms play a role in collaborative inhibition. (PsycINFO Database Record (c) 2015 APA, all rights reserved).

Several recent papers have reported long-term structural priming effects in experiments where previous patterns of experience with the double object and prepositional object constructions are shown to affect later patterns of language production for those constructions. The experiments reported in this paper address the extent to which these long-term priming effects are modulated by the participants' patterns of experience with particular verbs within the double object and prepositional object constructions. The results of three experiments show that patterns of experience with particular verbs using the double object or prepositional object constructions do not have much effect on the shape of the longterm structural priming effects reported elsewhere in the literature. These findings lend support to the claim that structural priming is the result of adaptations to the language production system that occur on an abstract, structural level of representation that is separate from representations regarding the behavior of particular lexical items in particular constructions [e.g., Chang, F., Dell, G. S., & Bock, K. (2006). Becoming syntactic. Psychological Review, 113, 234-272]. 2007 Elsevier Inc. All rights reserved.

Research has shown that adults' lexical-semantic representations are surprisingly malleable. For instance, the interpretation of ambiguous words (e.g., bark) is influenced by experience such that recently encountered meanings become more readily available (Rodd et al., 2016, 2013). However, the mechanism underlying this word-meaning priming effect remains unclear, and competing accounts make different predictions about the extent to which information about word meanings that is gained within one modality (e.g., speech) is transferred to the other modality (e.g., reading) to aid comprehension. In two Web-based experiments, ambiguous target words were primed with either written or spoken sentences that biased their interpretation toward a subordinate meaning, or were unprimed. About 20 min after the prime exposure, interpretation of these target words was tested by presenting them in either written or spoken form, using word association (Experiment 1, N = 78) and speeded semantic relatedness decisions (Experiment 2, N = 181). Both experiments replicated the auditory unimodal priming effect shown previously (Rodd et al., 2016, 2013) and revealed significant cross-modal priming: primed meanings were retrieved more frequently and swiftly across all primed conditions compared with the unprimed baseline. Furthermore, there were no reliable differences in priming levels between unimodal and cross-modal prime-test conditions. These results indicate that recent experience with ambiguous word meanings can bias the reader's or listener's later interpretation of these words in a modality-general way. We identify possible loci of this effect within the context of models of long-term priming and ambiguity resolution. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

The current research looked at how listening to music affects eye movements when college students read natural passages for comprehension. Two studies found that effects of music depend on both frequency of the word and dynamics of the music. Study 1 showed that lexical and linguistic features of the text remained highly robust predictors of looking times, even in the music condition. However, under music exposure, (a) readers produced more rereading, and (b) gaze duration on words with very low frequency were less predicted by word length, suggesting disrupted sublexical processing. Study 2 showed that these effects were exacerbated for a short period as soon as a new song came into play. Our results suggested that word recognition generally stayed on track despite music exposure and that extensive rereading can, to some extent, compensate for disruption. However, an irrelevant auditory signal may impair sublexical processing of low-frequency words during first-pass reading, especially when the auditory signal changes dramatically. These eye movement patterns are different from those observed in some other scenarios in which reading comprehension is impaired, including mindless reading.

We investigated the mechanisms underlying sandwich priming, a procedure in which a brief preprime target presentation precedes the conventional mask-prime-target sequence, used to study orthographic similarity. Lupker and Davis (2009) showed the sandwich paradigm enhances orthographic priming effects: With primes moderately related to targets, sandwich priming produced significant facilitation, but conventional priming did not. They argued that unlike conventional priming, sandwich priming is not susceptible to an uncontrolled counteractive inhibitory process, lexical competition, that cancels out moderate facilitation effects. They suggest lexical competition is eliminated by preactivating the target's representation, privileging the target over similar lexical units (competitors). As such, it better measures orthographic relatedness between primes and targets, a key purpose of many priming studies. We tested whether elimination of lexical competition could indeed account for the observed orthographic priming boost with sandwich priming. In three lexical decision experiments and accompanying simulations with a competitive network model, we compared priming effects in three preprime procedures: no preprime (conventional), identity (target) preprime (sandwich), and competitor preprime (included to exacerbate lexical competition). The related prime conditions consisted of replaced-letters, shared neighbor (one-letter-different from both competitor preprime and target), and transposed-all-letter nonword primes. Contrary to the model's predictions, the competitor preprime did not attenuate (Experiment 1) or even reverse the priming effect (Experiment 2). Moreover, the competitor enabled facilitatory priming that was absent with no preprime (Experiment 3). These data suggested that the sandwich orthographic boost could not be attributed to reduced lexical competition but rather to prelexical processes in word recognition.

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 after reading recalled the text from memory. The results showed that readers spent longer total fixation time and had better memory for task-relevant than irrelevant text information. During the course of reading, head-to-screen distance and the speed of head motion decreased more for relevant than irrelevant text segments. The results support the dynamic engagement hypothesis: there is task-induced fluctuation in cognitive engagement during reading. Moreover, the results suggest two types of engagement processes: transient and sustained engagement. The former refers to fast, momentary changes, whereas the latter refers to slower changes in the level of engagement observed across the reading task. The novel combination of eye and postural movement recordings proved to be useful in studying how readers embody the cognitive task demands during reading.

It has often been shown that intentional recollection is influenced by context manipulations, such as context reinstatement (e.g., Smith, 2013; Smith & Vela, 2001), but whether or not automatic retrieval (e.g., Jacoby, 1991) is likewise context dependent remains an open question. Here, we present two experiments that examined effects of context manipulations on indirect measures of memory. The first experiment tested anagram completion, and the second experiment used word fragment completion to test effects of context reinstatement; both experiments found reinstatement effects. To address potential problems of explicit contamination, we also asked participants if they were aware of the priming manipulations. Separating participants according to their test awareness showed effects of context manipulations for both aware and unaware participants. A greater effect size was found for aware participants only in Experiment 1, in which participants had enough time on each test trial for recollection to be used. We conclude that context reinstatement does affect automatic retrieval. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

Recollection without remembering is a counterintuitive phenomenon that violates a traditional assumption of source memory models-namely, that accurate item memory is a necessary precondition for remembering source details that accompanied an item's presentation. The dual-recollection model explains recollection without remembering as a by-product of the contrasting effects of target and context recollection on item tests versus source tests. We pitted that explanation against 2 others that preserve the traditional assumption, one based on hypothesized testing artifacts and the other derived from multivariate signal detection theory. Our experiments focused on a manipulation that, according to dual-recollection theory, should drive source memory and item memory in opposite directions. In 2 experiments, studied items were tagged with 3 source details (voice gender, taxonomic category, and list), such that either (a) the 3 details were consistent with each other or (b) 1 detail was inconsistent with the other 2. As predicted, source memory was better but item memory was worse when source details were consistent with each other. The recollection without remembering effect was observed in both experiments, and as predicted by dual-recollection theory, it was more robust when item memory was worse than when it was better. A further instance of recollection without remembering was detected that involved distractors rather than presented items. (PsycINFO Database Record (c) 2018 APA, all rights reserved).
