Abstract:
Setting the alarm: Word emotional attributes require consolidation to be operational.
Demonstrations of emotional Stroop in conditioned made-up words are flawed because of the lack of task ensuring similar word encoding across conditions. Here, participants were trained on associations between made-up words (e.g. 'drott') and pictures with an alarming or neutral content (e.g. 'a dead sheep' vs. 'a munching cow') in a situation that required attention to both ends of each association. To test whether word emotional attributes need to consolidate before they can hijack attention, one set of associations was learned seven days before the test, whereas the other set was learned either six hrs or immediately before the test. The novel words' ability to evoke their emotional attributes was assessed by using both Stroop and an auditory analogue called pause detection. Matching words and pictures was harder for alarming associations. However, similar learning rate and forgetting at seven days were observed for both types of associations. Pause detection revealed no emotion effect for same-day (i.e. unconsolidated) associations, but robust interference for seven-day-old (i.e. consolidated) alarming associations. Attention capture was found in the emotional Stroop as well, though only when trial n'1 referred to a same-day association. This task also showed stronger response repetition priming (independently of emotion) when trials n and n'1 both tapped into seven-day-old associations. Word emotional attributes hence take between six hrs and seven days to be operational. Moreover, age interactions between consecutive trials can be used to gauge implicitly the indirect (relational) episodic associations that develop in the meantime between the memories of individual items.

Abstract:
Generalization from newly learned words reveals structural properties of the human reading system
Connectionist accounts of quasiregular domains, such as spelling-sound correspondences in English, represent exception words (e.g. pint) amid regular words (e.g. mint) via a graded "warping" mechanism. Warping allows the model to extend the dominant pronunciation to nonwords (regularization) with minimal interference (spillover) from the exceptions. We tested for a behavioral marker of warping by investigating the degree to which participants generalized from newly learned made-up words, which ranged from sharing the dominant pronunciation (regulars), a subordinate pronunciation (ambiguous), or a previously nonexistent (exception) pronunciation. The new words were learned over 2 days, and generalization was assessed 48 hr later using nonword neighbors of the new words in a tempo naming task. The frequency of regularization (a measure of generalization) was directly related to degree of warping required to learn the pronunciation of the new word. Simulations using the Plaut, McClelland, Seidenberg, and Patterson (1996) model further support a warping interpretation. These findings highlight the need to develop theories of representation that are integrally tied to how those representations are learned and generalized.

Abstract:
Improved memory for information learnt before alcohol use in social drinkers tested in a naturalistic setting
Alcohol is known to facilitate memory if given after learning information in the laboratory; we aimed to investigate whether this effect can be found when alcohol is consumed in a naturalistic setting. Eighty-eight social drinkers were randomly allocated to either an alcohol self-dosing or a sober condition. The study assessed both retrograde facilitation and alcohol induced memory impairment using two independent tasks. In the retrograde task, participants learnt information in their own homes, and then consumed alcohol ad libitum. Participants then undertook an anterograde memory task of alcohol impairment when intoxicated. Both memory tasks were completed again the following day. Mean amount of alcohol consumed was 82.59 grams over the evening. For the retrograde task, as predicted, both conditions exhibited similar performance on the memory task immediately following learning (before intoxication) yet performance was better when tested the morning after encoding in the alcohol condition only. The anterograde task did not reveal significant differences in memory performance post-drinking. Units of alcohol drunk were positively correlated with the amount of retrograde facilitation the following morning. These findings demonstrate the retrograde facilitation effect in a naturalistic setting, and found it to be related to the self-administered grams of alcohol.

Abstract:
Sleep not just protects memories against forgetting, it also makes them more accessible
Two published datasets (Dumay & Gaskell, 2007, Psychological Science; Tamminen, Payne, Stickgold, Wamsley, & Gaskell, 2010, Journal of Neuroscience) showing a positive influence of sleep on declarative memory were re-analyzed, focusing on the "fate" of each item at the 0-h test and 12-h retest. In particular, I looked at which items were retrieved at test and "maintained" (i.e. not forgotten) at retest, and which items were not retrieved at test, but eventually "gained" at retest. This gave me separate estimates of protection against loss and memory enhancement, which the classic approach relying on net recall/recognition levels has remained blind to. In both free recall and recognition, the likelihood of maintaining an item between test and retest, like that of gaining one at retest, was higher when the retention interval was filled with nocturnal sleep, as opposed to day-time (active) wakefulness. And, in both cases, the effect of sleep was stronger on gained than maintained items. Thus, if sleep indeed protects against retroactive, unspecific interference, it also clearly promotes access to those memories initially too weak to be retrieved. These findings call for an integrated approach including both passive (cell-level) and active (systems-level) consolidation, possibly unfolding in an opportunistic fashion.

Abstract:
Overnight lexical consolidation revealed by speech segmentation.
Two experiments explored the consolidation of spoken words, and assessed whether post-sleep novel competitor effects truly reflect engagement of these novel words in competition for lexical segmentation. Two types of competitor relationships were contrasted: the onset-aligned case (such as "frenzylk"), where the novel word is a close variant of the existing word: they start at the same time point and overlap on most of their segments; and the fully embedding case (such as "lirmucktoze"), where the existing word corresponds to a smaller embedded portion of its novel competitor and is thus less noticeable. Experiment 1 (pause detection) revealed a similar performance for both cases, with no competitor effect immediately after exposure, but significant inhibition after 24 h and seven days. Experiment 2 (word spotting) produced exactly the same pattern; however, as is the case with existing word carriers (cf. McQueen, Norris, & Cutler, 1994), the inhibition was much stronger for fully embedded than for onset-aligned targets (e.g. "lirmuckt" vs. "frenzyl"). Meanwhile, explicit measures of learning, i.e. free recall and recognition, improved over time. These results cannot be explained by either consolidation of episodic traces or acquisition of new phonological/dialectal variants. We argue instead that they reflect a general trait of vocabulary learning and consolidation.

Abstract:
Auditory Selective Adaptation Moment by Moment, at Multiple Timescales
Over the course of a lifetime, adults develop perceptual categories for the vowels and consonants in their native language, based on the distribution of those sounds in their environment. However, in any given listening situation, the short-term distribution of sounds can cause changes in this long-term categorization. For example, if the same sound (the “adaptor”) is heard many times in a short period of time, listeners adapt and become less prone to hearing that sound. Although hundreds of speech selective adaptation experiments have been published, there is almost no information about how long this adaptation lasts. Using stimuli chosen to produce very large initial adaptation, we test adaptation effects with essentially no delay, and with delays of 25 min, 90 min, and 5.5 hr; these tests probe the duration of adaptation both in the (single) ear to which the adaptor was presented, and in the opposite ear. Reliable adaptation remains 5.5 hours after exposure in the same-ear condition, whereas it is undetectable at 90 min in the opposite ear. Surprisingly, the amount of residual adaptation is largely unaffected by whether the listener is exposed to speech between adaptation and test, unless the speech shares critical acoustic properties with the adapting sounds. Analyses of the shifts on three time scales (seconds, minutes, and hours) provide information about the multiple levels of analysis that the speech signal undergoes.

Abstract:
Searching for syllabic coding units in speech perception
Two auditory priming experiments tested whether the effect of final phonological overlap relies on syllabic representations. Amount of shared phonemic information and syllabic status of the overlap between nonword primes and targets were varied orthogonally. In the related conditions, CV.CCVC items shared the last syllable (e.g.. vi.klyd-pε ̃.klyd) or the last syllable minus one phoneme (e.g.. vi.flyd-pε ̃.klyd); conversely, CVC.CVC items shared the last syllable (e.g.. ) or the last syllable plus one phoneme (e.g.. ). Both experiments required participants to repeat back the targets, with Experiment 2 including foils (e.g.. vyglεt-buglεf). Foils made shadowers adopt a more conservative mode, but had no systematic influence on the magnitude of the final facilitation. More importantly, neither set of data fully aligned itself with the syllabic hypothesis. These results therefore argue against the idea that syllables serve as coding units in speech perception. © 2012 Elsevier Inc.

Abstract:
Exploring phonological encoding through repeated segments
Five experiments explored the influence of repeated phonemes on the production of short utterances. In Experiment 1 coloured object naming showed faster latencies when colour and object started with the same phoneme ('green goat') than when they did not; the opposite was found when colour and object were named on consecutive trials ('green' - 'goat'). Experiments 2 and 3 focused on adjective-noun phrases and showed no effect of repeated phonemes on either acoustical duration of speeded responses, or latencies in a delayed variant of the task, suggesting a higher-level - rather than articulatory - locus of the effect. Experiments 4 and 5 demonstrated that the facilitation induced by repeated segments is not specific to word onset ('green chain') and is independent of whether or not the repeated phonemes occupy the same within-word position ('green flag'). These results indicate that in the production of multiple words, word forms are concurrently activated and evoke phonological segments represented in a position-nonspecific manner. © 2008 Psychology Press, an imprint of the Taylor & Francis Group.

Abstract:
Reading spoken words: orthographic effects in auditory priming.
Three experiments examined the involvement of orthography in spoken word processing using a task - unimodal auditory priming with offset overlap - taken to reflect activation of prelexical representations. Two types of prime-target relationship were compared; both involved phonological overlap, but only one had a strong orthographic overlap (e.g. dream-gleam vs. scheme-gleam). In Experiment 1, which used lexical decision, phonological overlap facilitated target responses in comparison with an unrelated condition (e.g. stove-gleam). More importantly, facilitation was modulated by degree of orthographic overlap. Experiment 2 employed the same design as Experiment 1, but with a modified procedure aimed at eliciting swifter responses. Again, the phonological priming effect was sensitive to the degree of orthographic overlap between prime and target. Finally, to test whether this orthographic boost was caused by congruency between response type and valence of the prime-target overlap, Experiment 3 used a pseudoword detection task, in which participants responded "yes" to novel words and "no" to known words. Once again phonological priming was observed, with a significant boost in the orthographic overlap condition. These results indicate a surprising level of orthographic involvement in speech perception, and provide clear evidence for mandatory orthographic activation during spoken word recognition.

Abstract:
Sleep-associated changes in the mental representation of spoken words.
The integration of a newly learned spoken word form with existing knowledge in the mental lexicon is characterized by the word form's ability to compete with similar-sounding entries during auditory word recognition. Here we show that although the mere acquisition of a spoken form is swift, its engagement in lexical competition requires an incubation-like period that is crucially associated with sleep. Words learned at 8 p.m. do not induce (inhibitory) competition effects immediately, but do so after a 12-hr interval including a night's sleep, and continue to induce such effects after 24 hr. In contrast, words learned at 8 a.m. do not show such effects immediately or after 12 hr of wakefulness, but show the effects only after 24 hr, after sleep has occurred. This time-course dissociation is best accommodated by connectionist and neural models of learning in which sleep provides an opportunity for hippocampal information to be fed into long-term neocortical memory.

Abstract:
Time pressure and phonological advance planning in spoken production
Current accounts of spoken production debate the extent to which speakers plan ahead. Here, we investigated whether the scope of phonological planning is influenced by changes in time pressure constraints. The first experiment used a picture-word interference task and showed that picture naming latencies were shorter when word distractors shared the final segments with the picture name. Experiment 2 used the same paradigm but with colored pictures to elicit determiner + adjective + noun phrases. Latencies were shorter when the distractor overlapped phonologically with the picture name. Finally, Experiment 3 demonstrated that in colored picture naming without distractors, latencies were shorter when the object noun began with the same phoneme as the color adjective. Crucially, in all experiments introduction of a response deadline accelerated latencies, but did not alter the relative magnitude of the priming effects. In sum, pressure to provide a swift response does not reduce the scope of phonological planning. © 2006 Elsevier Inc. All rights reserved.

Do words go to sleep? Exploring consolidation of spoken forms through direct and indirect measures
We address the notion of integration of new memory representations and the potential dependence of this phenomenon on sleep, in light of recent findings on the lexicalization of spoken words. A distinction is introduced between measures tapping directly into the strength of the newly acquired knowledge and indirect measures assessing the influence of this knowledge on spoken word identification.

Abstract:
Lexical competition and the acquisition of novel words.
Three experiments examined the involvement of newly learnt words in lexical competition. Adult participants were familiarized with novel nonsense sequences that overlapped strongly with existing words (e.g. cathedruke, derived from cathedral) through repeated presentation in a phoneme-monitoring task. Experiment 1 looked at the immediate effects of exposure to these sequences, with participants showing familiarity with the form of the novel sequences in a two-alternative forced choice task. The effect of this exposure on lexical competition was examined by presenting the existing words (e.g. cathedral) in a lexical decision task. The immediate effect of the exposure was facilitatory, suggesting that the novel words had activated the representation of the closest real word rather than developing their own lexical representations. In Experiment 2, inhibitory lexical competition effects emerged over the course of 5 days for offset-diverging (e.g. cathedruke-cathedral) but not onset-diverging (e.g. yothedral-cathedral) novel words. Experiment 3 disentangled the roles of time and level-of-exposure in the lexicalization process and assessed the generality of the observed lexical inhibition using pause detection. A single, concentrated exposure session was used, which resulted in good recognition performance soon after. Lexicalization effects were absent immediately after exposure but emerged 1 week later, despite no intervening exposure to the novel items. These results suggest that integrating a novel word into the mental lexicon can be an extended process: phonological information is learnt swiftly, but full integration with existing items develops at a slower rate.

Abstract:
The role of the syllable in lexical segmentation in French: word-spotting data.
Three word-spotting experiments assessed the role of syllable onsets and offsets in lexical segmentation. Participants detected CVC words embedded initially or finally in bisyllabic nonwords with aligned (CVC.CVC) or misaligned (CV.CCVC) syllabic structure. A misalignment between word and syllable onsets (Experiment 1) produced a greater perceptual cost than a misalignment between word and syllable offsets (Experiments 2 and 3). These results suggest that listeners rely on syllable onsets to locate the beginning of words. The implications for theories of lexical access in continuous speech are discussed.

Abstract:
Behavioral and electrophysiological study of phonological priming between bisyllabic spoken words.
Phonological priming between bisyllabic (CV.CVC) spoken items was examined using both behavioral (reaction times, RTs) and electrophysiological (event-related potentials, ERPs) measures. Word and pseudoword targets were preceded by pseudoword primes. Different types of final phonological overlap between prime and target were compared. Critical pairs shared the last syllable, the rime or the coda, while unrelated pairs were used as controls. Participants performed a target shadowing task in Experiment 1 and a delayed lexical decision task in Experiment 2. RTs were measured in the first experiment and ERPs were recorded in the second experiment. The RT experiment was carried out under two presentation conditions. In Condition 1 both primes and targets were presented auditorily, while in Condition 2 the primes were presented visually and the targets auditorily. Priming effects were found in the unimodal condition only. RTs were fastest for syllable overlap, intermediate for rime overlap, and slowest for coda overlap and controls that did not differ from one another. ERPs were recorded under unimodal auditory presentation. ERP results showed that the amplitude of the auditory N400 component was smallest for syllable overlap, intermediate for rime overlap, and largest for coda overlap and controls that did not differ from one another. In both experiments, the priming effects were larger for word than for pseudoword targets. These results are best explained by the combined influences of nonlexical and lexical processes, and a comparison of the reported effects with those found in monosyllables suggests the involvement of rime and syllable representations.
