Me: I make decimal porcelain under the page frock of every hapless field mouse diver. No glimpses of syringes from the corner of my eye for me -1 just went to sleep in one place and woke in another.) A note taped to my chest hinted that I was now in my own form of Witness Protection - call it Betrayer Protection. Could it be that I am the only prisoner here, that everyone else, rather than being in the same boat, is standing in shallow water, just watching me, waiting for the day when I make an inevitable slip of the tongue? How, then, could there even be a high school where he could teach history?

Freud proposed that slips of the tongue, including apparently simple ones, always have a sense and constitute « a half-success and a half-failure » compromise resulting from defensive mechanisms. A total of 55 subjects participated in a French adaptation of the or SLIP-technique including 32 \"neutral\" and 32 taboo spoonerisms and measures of defensiveness. In accordance with a psychoanalytical and empirically supported distinction, we considered two kinds of defenses: elaborative or primary process and inhibitory or secondary process defenses, which were operationalized with the GeoCat and the Phonological-Nothing (PN) WordList, respectively. The GeoCat is a validated measure of primary process mentation and the PN WordList was shown to measure the defensive avoidance of language ambiguity. Participants produced 37 slips, with no significant difference in the number of \"neutral\" and taboo slips. The GeoCat and the N/PN parameters explained 30% of the variance in the production of parapraxes, confirming the defensive logics of slips. When dividing the population into lowly and highly defensive participants (with the Marlowe Crowne Social Desirability scale), primary process mentation appears as a baseline default defense, but only highly defensive participants mobilize an additional inhibitory secondary process type of defense. Taking into account the difference between taboo and \"neutral\" parapraxes, highly defensive participants made 2.7 times more taboo parapraxes than lowly defensive participants. However, if \"neutral\" parapraxes in both subgroups followed the same logic as the total group of parapraxes (significant contribution of primary process mentation in lowly defensives and of primary and secondary process mentation in highly defensives), these measures had no contribution to explain the occurrence of taboo parapraxes. We propose that Motley et al.'s prearticulatory editor, ensuring the censorship over taboo parapraxes, is an external instance of inhibition, proximal to uttering, equivalent to the censorship between the systems Preconscious and Conscious in Freud's metapsychology. By contrast, the defenses measured in this research are internal, intimate control systems, probing for the censorship between the systems Unconscious and Preconscious, this is, for repression. This study contributes to support a psychodynamic explanatory model for the production of parapraxes.

The present study was aimed at investigating different aspects of Executive Functions (EF) in children with Developmental Dyslexia (DD). A neuropsychological battery tapping verbal fluency, spoonerism, attention, verbal shifting, short-term and working memory was used to assess 60 children with DD and 65 with typical reading (TR) abilities. Compared to their controls, children with DD showed deficits in several EF domains such as verbal categorical and phonological fluency, visual-spatial and auditory attention, spoonerism, verbal and visual short-term memory, and verbal working memory. Moreover, exploring predictive relationships between EF measures and reading, we found that spoonerism abilities better explained word and non-word reading deficits. Although to a lesser extent, auditory and visual-spatial attention also explained the increased percentage of variance related to reading deficit. EF deficits found in DD are interpreted as an expression of a deficient functioning of the Central Executive System and are discussed in the context of the recent temporal sampling theory.

Purpose: Delayed auditory feedback (DAF) interferes with speech output. DAF causes distorted and disfluent productions and errors in the serial order of produced sounds. Although DAF has been studied extensively, the specific patterns of elicited speech errors are somewhat obscured by relatively small speech samples, differences across studies, and uncontrolled variables. The goal of this study was to characterize the types of serial order errors that increase under DAF in a systematic syllable sequence production task, which used a closed set of sounds and controlled for speech rate. Method: Sixteen adult speakers repeatedly produced CVCVCV (C = consonant, V = vowel) sequences, paced to a \"visual metronome,\" while hearing self-generated feedback with delays of 0-250 ms. Listeners transcribed recordings, and speech errors were classified based on the literature surrounding naturally occurring slips of the tongue. A series of mixed-effects models were used to assess the effects of delay for different error types, for error arrival time, and for speaking rate. Results: DAF had a significant effect on the overall error rate for delays of 100 ms or greater. Statistical models revealed significant effects (relative to zero delay) for vowel and syllable repetitions, vowel exchanges, vowel omissions, onset disfluencies, and distortions. Serial order errors were especially dominated by vowel and syllable repetitions. Errors occurred earlier on average within a trial for longer feedback delays. Although longer delays caused slower speech, this effect was mediated by the run number (time in the experiment) and small compared with those in previous studies. Conclusions: DAF drives a specific pattern of serial order errors. The dominant pattern of vowel and syllable repetition errors suggests possible mechanisms whereby DAF drives changes to the activity in speech planning representations, yielding errors. These mechanisms are outlined with reference to the GODIVA (Gradient Order Directions Into Velocities of Articulators) model of speech planning and production.

Purpose: A dual-task paradigm was implemented to investigate how noise type and sentence context may interact with age and hearing loss to impact word recall during speech recognition. Method: Three noise types with varying degrees of temporal/spectrotemporal modulation were used: speech-shaped noise, speech-modulated noise, and three-talker babble. Participant groups included younger listeners with normal hearing (NH), older listeners with near-normal hearing, and older listeners with sensorineural hearing loss. An adaptive measure was used to establish the signal-to-noise ratio approximating 70% sentence recognition for each participant in each noise type. A word-recall task was then implemented while matching speech-recognition performance across noise types and participant groups. Random-intercept linear mixed-effects models were used to determine the effects of and interactions between noise type, sentence context, and participant group on word recall. Results: The results suggest that noise type does not significantly impact word recall when word-recognition performance is controlled. When data from noise types were pooled and compared with quiet, and recall was assessed: older listeners with near-normal hearing performed well when either quiet backgrounds or high sentence context (or both) were present, but older listeners with hearing loss performed well only when both quiet backgrounds and high sentence context were present. Younger listeners with NH were robust to the detrimental effects of noise and low context. Conclusions: The general presence of noise has the potential to decrease word recall, but type of noise does not appear to significantly impact this observation when overall task difficulty is controlled. The presence of noise as well as deficits related to age and/or hearing loss appear to limit the availability of cognitive processing resources available for working memory during conversation in difficult listening environments. The conversation environments that impact these resources appear to differ depending on age and/or hearing status.

The sixteen SOTs examined are on-air ones produced by native English TV presenters and anchors. Although these SOTs seem funny, they reflect a great deal about how naturalistic speech is assembled and produced. Acoustic analysis is also brought to bear on the present investigation with the aim of providing accurate findings. Several psycholinguistic models are invoked in the analysis, and Praat 6 is used to provide spectrograms and waveforms for the errors detected. The present study concludes that the SOTs examined in the present corpus reveal much about the processing of erroneous speech. Substitution errors, being the most prominent, exhibit uniform processing through a replacement on phonemic or higher levels. As for anticipation errors, they prove to be irregular in their production. Other errors are sparse in the present corpus, and cannot be generalized over a wide range of instances, since they occur either once or twice.

Many have thought that exercises of skill are intentional. The argument of the paper is that this thesis fails to account for important types of mistakes and errors. In what psychologists and linguists call “verbal slips with semantic bias”, a speaker mistakenly switches, reverses, or blends certain conceptual contents. Nevertheless, the speaker has successfully exercised an intellectual skill, insofar as her slip uses concepts in conformity to semantic and logical rules. To flesh out how one might successfully exercise skills without doing so intentionally, the paper appeals to the idea of habit. Verbal slips thus show how human skillfulness has a considerably wider scope than is often supposed.

The constant internal monitoring of speech is a crucial feature to ensure the fairly error-free process of speech production. It has been argued that internal speech monitoring takes place through detection of conflict between different response options or “speech plans”. Speech errors are thought to occur because two (or more) competing speech plans become activated, and the speaker is unable to inhibit the erroneous plan(s) prior to vocalization. A prime example for a speech plan that has to be suppressed is the involuntary utterance of a taboo word. The present study seeks to examine the suppression of involuntary taboo word utterances. We used the “Spoonerisms of Laboratory Induced Predisposition” (SLIP) paradigm to elicit two competing speech plans, one being correct and one embodying either a taboo word or a non-taboo word spoonerism. Behavioral data showed that inadequate speech plans generally were effectively suppressed, although more effectively in the taboo word spoonerism condition. Event-related potential (ERP) analysis revealed a broad medial frontal negativity (MFN) after the target word pair presentation, interpreted as reflecting conflict detection and resolution to suppress the inadequate speech plan. The MFN was found to be more pronounced in the taboo word spoonerism compared to the neutral word spoonerism condition, indicative of a higher level of conflict when subjects suppressed the involuntary utterance of taboo words.

Phonological awareness is a complex and multifaceted skill which plays an essential role in the development of an individual’s language and literacy abilities. Phonological skills are indeed dramatically impaired in people with dyslexia, at any age and across languages, whereas their development in bilinguals is less clear. In addition, the interaction between bilingualism and dyslexia in this domain is still under-investigated. The aim of this paper is to provide new experimental evidence on this topic by exploring the phonological competence in Italian of monolingual and bilingual children with and without dyslexia. To this purpose, we developed three tasks, assessing nonword repetition, rhyme detection and spoonerisms, which we administered to 148 10-year-old children in two distinct studies. In Study 1, we found that two groups of L2 Italian typically developing bilinguals, having either Arabic or Romanian as L1, performed similarly to Italian monolinguals in all measures, pointing to absence of both bilingualism-related and L1-related effects in these tasks. In Study 2, we administered the same tasks to four groups of children: Italian monolinguals with dyslexia, Italian monolingual typically developing children, L2 Italian bilinguals with dyslexia and L2 Italian bilingual typically developing children. Results showed that children with dyslexia, both monolingual and bilingual, exhibited significantly more difficulties than typically developing children in all three tasks, whereas bilinguals, consistent with Study 1, performed similarly to their monolingual peers. In addition, no negative effects of bilingualism in dyslexia were found, indicating that being bilingual does not provide additional difficulties to children with dyslexia.

In computational models of reading, written words can be read using print-to-sound and/or print-to-meaning pathways. Neuroimaging data associate dorsal stream regions (left posterior occipitotemporal cortex, intraparietal cortex, dorsal inferior frontal gyrus [dIFG]) with the print-to-sound pathway and ventral stream regions (left anterior fusiform gyrus, middle temporal gyrus) with the print-to-meaning pathway. In 69 typical adults, we investigated whether resting state functional connectivity (RSFC) between the visual word form area (VWFA) and dorsal and ventral regions correlated with phonological (nonword reading, nonword repetition, spoonerisms), lexical-semantic (vocabulary, sensitivity to morpheme units in reading), and general literacy (word reading, spelling) skills. VWFA activity was temporally correlated with activity in both dorsal and ventral reading regions. In pre-registered whole-brain analyses, spoonerisms performance was positively correlated with RSFC between the VWFA and left dorsal regions (dIFG, superior parietal and intraparietal cortex). In exploratory region-of-interest analyses, VWFA-dIFG connectivity was also positively correlated with nonword repetition, spelling, and vocabulary. Connectivity between the VWFA and ventral stream regions was not associated with performance on any behavioural measure, either in whole-brain or region-of-interest analyses. Our results suggest that tasks such as spoonerisms and spellings, which are both complex (i.e., involve multiple subprocesses) and have high between-subject variability, provide greater opportunity for observing resting-state brain-behaviour associations. However, the complexity of these tasks limits the conclusions we can draw about the specific mechanisms that drive these associations. Future research would benefit from constructing latent variables from multiple tasks tapping the same reading subprocess.
