Humanitarian Crisis in Indian Jammu and Kashmir: An Analysis

Human rights violations in the part of Kashmir ruled by India are the subject of this article. The part of Kashmir under Indian administration suffers from the ongoing violation of human rights. Their daily lives now involve everything from political repression and the oppressive conditions of free speech to mass murders, forced disappearances, torture, rape, and sexual abuse. Extremist organizations, border guards, and the Indian Central Reserve Police Force have all been charged with and found guilty of serious violations of human rights against Kashmiri civilians. The rebels in Kashmir believe that the part of the country that is ruled by India is a part of Pakistan. Thus, the only people who are allowed to live on that area are Pakistanis. However, the question of how far it is acceptable to create one's existence at the expense of ending the lives of people who are completely innocent and have no fault of their own other than the fact that they were born on that property emerges. Numerous questions have been raised by this upheaval, all of which deserve our serious attention and prompt resolution.

Functional and pragmatic parameters of speech acts with the explicit mode of ignorance in scientific dialogue

The article is about identifying functional aspects of 1st-person statements with the explicit mode of ignorance (messages like I do not know… / We don’t know… I don’t know / We don’t know ...) in scientific discussions as a genre of scientific discourse. The relevance of the analysis is predetermined by the necessity to study various parameters of discourse (including both epistemic and pragmatic) as closely connected. The main research method is contextual and pragmalinguistic analysis. The sources of the material are transcripts of modern English and Russian scientific discussions in various fields of knowledge. The article identifies the illocutionary properties of ignorant statements, establishes their pragmatic functions, as well as determines their position in the traditional classification of speech acts. Taking into account the illocutionary orientation of references to ignorance makes it possible to identify representative, interrogative, axiological varieties of ignorance messages as well as their subtypes differentiated on the basis of the degree of their expressiveness, their vector of evaluation, the nature of the representative and interrogative role of speech acts with the mode of ignorance: fully expressive and conditionally expressive, positive and negative, preventive and hesitative, etc. The criterion “pragmatic functions” helps us specify additional functions of references to ignorance in scientific dialogue: to indicate a certain degree of the speaker’s epistemic responsibility for their words, to serve as a means of avoiding the answer, a way to prevent criticism, etc. Moreover, the work identifies factors determining the illocutionary nature of ignorance speech acts: the surface structure of the message, the general context of utterance, the position of the ignorance message in the dialogical unity, sincerity and felicity conditions of speech acts formulated as ignorance messages. References to ignorance are concluded to be quite a significant phenomenon in the structure of scientific dialogue, since they perform a number of important functions in it. The analysis scheme can be used to study statements with other explicit modes (knowledge, opinions, etc.) in various types of discourse.

Understanding discourse in face-to-face settings: The impact of multimodal cues and listening conditions.

In face-to-face contexts, discourse is accompanied by various cues, like gestures and mouth movements. Here, we asked whether the presence of gestures and mouth movements benefits discourse comprehension under clear and challenging listening conditions and, if so, whether this multimodal benefit depends on the communicative environment in which interlocutors are situated. In two online experiments, participants watched videoclips of a speaker telling stories, and they answered yes-no questions about the content of each story. The speaker in the videos was spontaneously gesturing (or kept her hands still) and was wearing a surgical mask (or had her lips visible). The experiments differed in the communicative environment. In Experiment 1, the speaker narrated stories in silence, whereas the listener (participants) heard them in clear or degraded speech conditions (analogous to watching the news on TV in a quiet or noisy café). In Experiment 2, the speaker narrated the stories once in silence and once while listening to background noise, and the listener heard them in clear or degraded speech condition, respectively (analogous to listening to a friend in a quiet or noisy café). Across the experiments, we found that cospeech gestures facilitated discourse comprehension regardless of the listening conditions or the presence of a mask. In contrast, mouth movements were primarily helpful in challenging listening conditions. These findings indicate that both cues matter to listeners but to a different extent. Moreover, we found that the multimodal benefit to comprehension was similar regardless of the communicative environment. Thus, this study demonstrates the importance of both cospeech gestures and mouth movements to discourse comprehension, offering insights into the dynamic interplay between these cues under different communicative environments.

Hearing Impairment: Reduced Pupil Dilation Response and Frontal Activation During Degraded Speech Perception.

A relevant aspect of listening is the effort required during speech processing, which can be assessed by pupillometry. Here, we assessed the pupil dilation response of normal-hearing (NH) and hard of hearing (HH) individuals during listening to clear sentences and masked or degraded sentences. We combined this assessment with functional magnetic resonance imaging (fMRI) to investigate the neural correlates of the pupil dilation response. Seventeen NH participants (Mage = 46 years) were compared to 17 HH participants (Mage = 45 years) who were individually matched in age and educational level. Participants repeated sentences that were presented clearly, that were distorted, or that were masked. The sentence intelligibility level of masked and distorted sentences was 50% correct. Silent baseline trials were presented as well. Performance measures, pupil dilation responses, and fMRI data were acquired. HH individuals had overall poorer speech reception than the NH participants, but not for noise-vocoded speech. In addition, an interaction effect was observed with smaller pupil dilation responses in HH than in NH listeners for the degraded speech conditions. Hearing impairment was associated with higher activation across conditions in the left superior temporal gyrus, as compared to the silent baseline. However, the region of interest analysis indicated lower activation during degraded speech relative to clear speech in bilateral frontal regions and the insular cortex, for HH compared to NH listeners. Hearing impairment was also associated with a weaker relation between the pupil response and activation in the right inferior frontal gyrus. Overall, degraded speech evoked higher frontal activation than clear speech. Brain areas associated with attentional and cognitive-control processes may be increasingly recruited when speech is degraded and are related to the pupil dilation response, but this relationship is weaker in HH listeners. https://doi.org/10.23641/asha.27162135.

EEG based depression detection by machine learning: Does inner or overt speech condition provide better biomarkers when using emotion words as experimental cues?

BackgroundObjective diagnostic approaches need to be tested to enhance the efficacy of depression detection. Non-invasive EEG-based identification represents a promising area. AimsThe present EEG study addresses two central questions: 1) whether inner or overt speech condition result in higher diagnositc accuracy of depression detection; and 2) does the affective nature of the presented emotion words count in such diagnostic approach. MethodsA matched case-control sample consisting of 10 depressed subjects and 10 healthy controls was assessed. An EEG headcap containing 64 electrodes measured neural responses to experimental cues presented in the form of 15 different words that belonged to three emotional categories: neutral, positive, and negative. 120 experimental cues was presented for every participant, each containing an “inner speech” and an “overt speech” segment. An EEGNet neural network was utilized. ResultsThe highest diagnostic accuracy of the EEGNet model was observed in the case of the overt speech condition (i.e. 69.5%), while a an overall subject-wise accuracy of 80% was achieved by the model. Only a negligible difference in diagnostic accuracy could be found between aggregated emotion word categories, with the highest accuracy (i.e. 70.2%) associated with the presentation of positive emotion words. Model decision was primarily influenced by electrodes representing the regions of the left parietal, the left temporal lobe and the middle frontal areas. ConclusionsWhile the generalizability of our results is limited by the small sample size and potentially uncontrolled confounders, depression was associated with sensitive and presumably network-like aspects of these brain areas, potentially implying a higher level of emotion regulation that increases primarily in open communication.

Neuroplasticity of Speech-in-Noise Processing in Older Adults Assessed by Functional Near-Infrared Spectroscopy (fNIRS)

Functional near-infrared spectroscopy (fNIRS), a non-invasive optical neuroimaging technique that is portable and acoustically silent, has become a promising tool for evaluating auditory brain functions in hearing-vulnerable individuals. This study, for the first time, used fNIRS to evaluate neuroplasticity of speech-in-noise processing in older adults. Ten older adults, most of whom had moderate-to-mild hearing loss, participated in a 4-week speech-in-noise training. Their speech-in-noise performances and fNIRS brain responses to speech (auditory sentences in noise), non-speech (spectrally-rotated speech in noise) and visual (flashing chequerboards) stimuli were evaluated pre- (T0) and post-training (immediately after training, T1; and after a 4-week retention, T2). Behaviourally, speech-in-noise performances were improved after retention (T2 vs. T0) but not immediately after training (T1 vs. T0). Neurally, we intriguingly found brain responses to speech vs. non-speech decreased significantly in the left auditory cortex after retention (T2 vs. T0 and T2 vs. T1) for which we interpret as suppressed processing of background noise during speech listening alongside the significant behavioural improvements. Meanwhile, functional connectivity within and between multiple regions of temporal, parietal and frontal lobes was significantly enhanced in the speech condition after retention (T2 vs. T0). We also found neural changes before the emergence of significant behavioural improvements. Compared to pre-training, responses to speech vs. non-speech in the left frontal/prefrontal cortex were decreased significantly both immediately after training (T1 vs. T0) and retention (T2 vs. T0), reflecting possible alleviation of listening efforts. Finally, connectivity was significantly decreased between auditory and higher-level non-auditory (parietal and frontal) cortices in response to visual stimuli immediately after training (T1 vs. T0), indicating decreased cross-modal takeover of speech-related regions during visual processing. The results thus showed that neuroplasticity can be observed not only at the same time with, but also before, behavioural changes in speech-in-noise perception. To our knowledge, this is the first fNIRS study to evaluate speech-based auditory neuroplasticity in older adults. It thus provides important implications for current research by illustrating the promises of detecting neuroplasticity using fNIRS in hearing-vulnerable individuals.

Effect of early versus late onset of partial visual loss on judgments of auditory distance.

It is important to know whether early-onset vision loss and late-onset vision loss are associated with differences in the estimation of distances of sound sources within the environment. People with vision loss rely heavily on auditory cues for path planning, safe navigation, avoiding collisions, and activities of daily living. Loss of vision can lead to substantial changes in auditory abilities. It is unclear whether differences in sound distance estimation exist in people with early-onset partial vision loss, late-onset partial vision loss, and normal vision. We investigated distance estimates for a range of sound sources and auditory environments in groups of participants with early- or late-onset partial visual loss and sighted controls. Fifty-two participants heard static sounds with virtual distances ranging from 1.2 to 13.8 m within a simulated room. The room simulated either anechoic (no echoes) or reverberant environments. Stimuli were speech, music, or noise. Single sounds were presented, and participants reported the estimated distance of the sound source. Each participant took part in 480 trials. Analysis of variance showed significant main effects of visual status (p<0.05) environment (reverberant vs. anechoic, p<0.05) and also of the stimulus (p<0.05). Significant differences (p<0.05) were shown in the estimation of distances of sound sources between early-onset visually impaired participants and sighted controls for closer distances for all conditions except the anechoic speech condition and at middle distances for all conditions except the reverberant speech and music conditions. Late-onset visually impaired participants and sighted controls showed similar performance (p>0.05). The findings suggest that early-onset partial vision loss results in significant changes in judged auditory distance in different environments, especially for close and middle distances. Late-onset partial visual loss has less of an impact on the ability to estimate the distance of sound sources. The findings are consistent with a theoretical framework, the perceptual restructuring hypothesis, which was recently proposed to account for the effects of vision loss on audition.

Does meaningful background speech modulate predictability effects during Chinese reading?

ABSTRACT Previous research indicates that background speech disrupts reading comprehension processes, but it remains unclear whether the disruption derives from semantic or phonological speech properties, and whether it affects early lexical processing or later sentence integration. Native Chinese speaking participants read sentences containing high- or low-predictability words under meaningful Chinese speech, meaningless Uyghur speech or silence conditions. Results showed that Chinese but not Uyghur speech produced increased total fixations compared to reading in silence, suggesting disruption was semantic in nature. While a standard predictability effect was comparable across background speech conditions in target word analyses, this effect disappeared in the Chinese speech condition in later measures and regions. The findings suggest that Chinese background speech may delay higher order (post-lexical) processing associated with sentence integration during reading, with implications for the Interference-by-Process hypothesis.

Changes in visually and auditory attended audiovisual speech processing in cochlear implant users: A longitudinal ERP study

Limited auditory input, whether caused by hearing loss or by electrical stimulation through a cochlear implant (CI), can be compensated by the remaining senses. Specifically for CI users, previous studies reported not only improved visual skills, but also altered cortical processing of unisensory visual and auditory stimuli. However, in multisensory scenarios, it is still unclear how auditory deprivation (before implantation) and electrical hearing experience (after implantation) affect cortical audiovisual speech processing.Here, we present a prospective longitudinal electroencephalography (EEG) study which systematically examined the deprivation- and CI-induced alterations of cortical processing of audiovisual words by comparing event-related potentials (ERPs) in postlingually deafened CI users before and after implantation (five weeks and six months of CI use). A group of matched normal-hearing (NH) listeners served as controls. The participants performed a word-identification task with congruent and incongruent audiovisual words, focusing their attention on either the visual (lip movement) or the auditory speech signal. This allowed us to study the (top-down) attention effect on the (bottom-up) sensory cortical processing of audiovisual speech.When compared to the NH listeners, the CI candidates (before implantation) and the CI users (after implantation) exhibited enhanced lipreading abilities and an altered cortical response at the N1 latency range (90–150 ms) that was characterized by a decreased theta oscillation power (4–8 Hz) and a smaller amplitude in the auditory cortex. After implantation, however, the auditory-cortex response gradually increased and developed a stronger intra-modal connectivity. Nevertheless, task efficiency and activation in the visual cortex was significantly modulated in both groups by focusing attention on the visual as compared to the auditory speech signal, with the NH listeners additionally showing an attention-dependent decrease in beta oscillation power (13–30 Hz).In sum, these results suggest remarkable deprivation effects on audiovisual speech processing in the auditory cortex, which partially reverse after implantation. Although even experienced CI users still show distinct audiovisual speech processing compared to NH listeners, pronounced effects of (top-down) direction of attention on (bottom-up) audiovisual processing can be observed in both groups. However, NH listeners but not CI users appear to show enhanced allocation of cognitive resources in visually as compared to auditory attended audiovisual speech conditions, which supports our behavioural observations of poorer lipreading abilities and reduced visual influence on audition in NH listeners as compared to CI users.

The Association Between Stuttering Burden and Psychosocial Aspects of Life in Adults.

Stuttering is a speech condition that can have a major impact on a person's quality of life. This descriptive study aimed to identify subgroups of people who stutter (PWS) based on stuttering burden and to investigate differences between these subgroups on psychosocial aspects of life. The study included 618 adult participants who stutter. They completed a detailed survey examining stuttering symptomatology, impact of stuttering on anxiety, education and employment, experience of stuttering, and levels of depression, anxiety, and stress. A two-step cluster analytic procedure was performed to identify subgroups of PWS, based on self-report of stuttering frequency, severity, affect, and anxiety, four measures that together inform about stuttering burden. We identified a high- (n = 230) and a low-burden subgroup (n = 372). The high-burden subgroup reported a significantly higher impact of stuttering on education and employment, and higher levels of general depression, anxiety, stress, and overall impact of stuttering. These participants also reported that they trialed more different stuttering therapies than those with lower burden. Our results emphasize the need to be attentive to the diverse experiences and needs of PWS, rather than treating them as a homogeneous group. Our findings also stress the importance of personalized therapeutic strategies for individuals with stuttering, considering all aspects that could influence their stuttering burden. People with high-burden stuttering might, for example, have a higher need for psychological therapy to reduce stuttering-related anxiety. People with less emotional reactions but severe speech distortions may also have a moderate to high burden, but they may have a higher need for speech techniques to communicate with more ease. Future research should give more insights into the therapeutic needs of people highly burdened by their stuttering. https://doi.org/10.23641/asha.25582980.

LANGUAGE ASSESSMENT OF PRESCHOOL AND SCHOOL-AGE CHILDREN AT RISK FOR LANGUAGE DISORDERS IN RESIDENTIAL CARE SETTINGS

Adequate language development is central to a child's academic and social development. This study aimed to assess the language of 35 preschool and school-aged Portuguese children in residential care in four social institutions, using the Grelha de Observação da Linguagem (GOL-E) developed by Kay and Santos (2014), a validated tool in Portuguese. The results of the study showed that in terms of language competence, compared to the normative results expected for their age: a) Of the thirty-five children assessed, only three were at or above the 50th percentile; b) Twelve children were between the 5th and 25th percentiles; c) Eight children were in the 10th percentile; d) Of the children between the 11th and 12th percentiles, only one was in the 90th and 75th percentiles; e) Eleven children were in the 10th and 25th percentiles; f) One child at the age of 12 was in the 5th percentile. Most of the children were in percentiles below those expected for their age group. According to the definition of speech and language disorders, we can observe that a group of these children fall under the condition of speech and language disorders, but have not been formally identified in the educational system, putting them at risk of failure in school and life. This study highlights the importance of language assessment and special education services for children living in institutions in Portugal. More studies with this population in these age groups are needed to better understand the language competencies of children living in residential care.&lt;p&gt; &lt;/p&gt;&lt;p&gt;&lt;strong&gt; Article visualizations:&lt;/strong&gt;&lt;/p&gt;&lt;p&gt;&lt;img src="/-counters-/edu/0058/a.php" alt="Hit counter" /&gt;&lt;/p&gt;

Academia’s next top bottom: Title IX as performative advocacy

ABSTRACT In this complaint biography, I consider how Title IX’s peri-performative protocols fail to address structural homophobia and transphobia. Peri-performativity is a spatial metaphor that theorizes conditions for speech and is explored in three ways. First, I use peri-performativity to investigate speech acts and silences that surround sexual harassment in academia. Second, Title IX’s peri-performative protocols often result in performative advocacy, which does not result in structural change. Third, the essay’s creative structure spatially renders peri-performativity to demonstrate how incidents of harassment operate in a larger heteroprofesssional network of signification that uniquely harms LGBTQ academicians.

Understanding speech in everyday conditions—Effects of room acoustics and noise

Understanding speech in noisy, indoor settings is a considerable challenge for listeners. Room acoustics, such as reverberation and heating, ventilation, and air conditioning (HVAC) noise, all contribute to such challenges. In the current study, the effects of different backgrounds were examined in anechoic versus reverberant conditions at two different signal-to-noise ratios (SNRs) were examined. 60 monolingual American English listeners transcribed spoken English sentences under different noisy conditions. Overall, we tested two acoustic conditions: anechoic and reverberant, reverberation time = 1.5 s, with four speech conditions (target speech only, or combined with HVAC noise, two-talker babble, or both) and two different SNRs (0 dB and -3 dB). Both the target and babble speech were female voices speaking in English. Complex backgrounds resulted in decreased performance, and the detrimental effects of such masking were accentuated by reverberation and lower SNR. This study serves as a basis for future research exploring the effects of room acoustics on speech intelligibility to gain a more wholistic understanding of speech perception under realistic conditions.

Neurophysiological correlates of the perceptual magnet effect in speech perception

This study investigated the Perceptual Magnet Effect (PME) in speech perception using behavioral and Event-Related Potentials (ERP) measures. There were two primary research questions: (1) whether category goodness rating influences speech discrimination with reduced sensitivity near the prototype and increased sensitivity in the vicinity of a poor exemplar, (2) whether the PME is domain-specific to speech sounds. Twenty adult native English speakers participated in identification, goodness rating, and discrimination tasks. The stimuli were synthesized vowels for /a/ and their nonspeech analogs by systematically varying the first two formants. ERP oddball conditions included four conditions presented in a counter-balanced order with the prototypical /a/ as the standard stimuli and its variants as deviants, and a non-prototypical /a/ as the standard and its variants as deviants, as well as the nonspeech matches. Results indicated that participants rated vowel category goodness based on the F2/F1 ratio for the /a/ sounds. Mismatch negativity amplitudes in the two speech conditions aligned with PME predictions, but similar patterns were also observed in the nonspeech conditions. The findings collectively demonstrated neurophysiological evidence for the perceptual organization of within-category variations in line with PME, which may transfer to auditory processing of similar acoustic patterns in nonspeech.

Listening effort under different rates of speech

Listening effort, the cognitive resources allocated to understand spoken language, is a critical issue in communication under adverse listening environments. The present study investigated how listening effort would be affected by differing speech tempos. The experiment involved 23 native Korean adults with normal hearing, who were presented with linguistically complex Korean sentences at five different speeds (35%∼200% of original time). The cognitive load associated with listening under various speech rate conditions was quantified employing a dual-task paradigm, where the increased listening effort would impair the performance on an additional cognitive task. Participants listened to the sentences while performing an n-back task and then repeated back the sentence they heard. The results found a significant effect of speech rate on the n-back task, with lower accuracies in the faster speech conditions. The additional task also increased the overall cognitive load of sentence recognition, leading to various speech errors, such as the omission of key content words, unnecessary additions, and substitutions with similar words. This demonstrates that increased cognitive load during listening impairs speech processing at multiple levels (e.g., semantic processing, retention of words in working memory), emphasizing the need to adjust speech tempos for better understanding and comfort in listeners.

Neural correlates of audiovisual narrative speech perception in children and adults on the autism spectrum: A functional magnetic resonance imaging study.

Autistic individuals show substantially reduced benefit from observing visual articulations during audiovisual speech perception, a multisensory integration deficit that is particularly relevant to social communication. This has mostly been studied using simple syllabic or word-level stimuli and it remains unclear how altered lower-level multisensory integration translates to the processing of more complex natural multisensory stimulus environments in autism. Here, functional neuroimaging was used to examine neural correlates of audiovisual gain (AV-gain) in 41 autistic individuals to those of 41 age-matched non-autistic controls when presented with a complex audiovisual narrative. Participants were presented with continuous narration of a story in auditory-alone, visual-alone, and both synchronous and asynchronous audiovisual speech conditions. We hypothesized that previously identified differences in audiovisual speech processing in autism would be characterized by activation differences in brain regions well known to be associated with audiovisual enhancement in neurotypicals. However, our results did not provide evidence for altered processing of auditory alone, visual alone, audiovisual conditions or AV- gain in regions associated with the respective task when comparing activation patterns between groups. Instead, we found that autistic individuals responded with higher activations in mostly frontal regions where the activation to the experimental conditions was below baseline (de-activations) in the control group. These frontal effects were observed in both unisensory and audiovisual conditions, suggesting that these altered activations were not specific to multisensory processing but reflective of more general mechanisms such as an altered disengagement of Default Mode Network processes during the observation of the language stimulus across conditions.

Neural Speech Tracking Highlights the Importance of Visual Speech in Multi-speaker Situations.

Visual speech plays a powerful role in facilitating auditory speech processing and has been a publicly noticed topic with the wide usage of face masks during the COVID-19 pandemic. In a previous magnetoencephalography study, we showed that occluding the mouth area significantly impairs neural speech tracking. To rule out the possibility that this deterioration is because of degraded sound quality, in the present follow-up study, we presented participants with audiovisual (AV) and audio-only (A) speech. We further independently manipulated the trials by adding a face mask and a distractor speaker. Our results clearly show that face masks only affect speech tracking in AV conditions, not in A conditions. This shows that face masks indeed primarily impact speech processing by blocking visual speech and not by acoustic degradation. We can further highlight how the spectrogram, lip movements and lexical units are tracked on a sensor level. We can show visual benefits for tracking the spectrogram especially in the multi-speaker condition. While lip movements only show additional improvement and visual benefit over tracking of the spectrogram in clear speech conditions, lexical units (phonemes and word onsets) do not show visual enhancement at all. We hypothesize that in young normal hearing individuals, information from visual input is less used for specific feature extraction, but acts more as a general resource for guiding attention.

God as the Condition of Speech: An Interpretation of Eugen Rosenstock‐Huessy's and Franz Rosenzweig's New Thinking

AbstractThe article offers an interpretation of the New Thinking of Rosenstock‐Huessy and Rosenzweig. It first explains the New Thinking in juxtaposition with a philosophical tradition that views reality as a problem of knowledge and conceptualizes the I's relation to reality as accomplished primarily through thought. The New Thinking is defined by its effort to understand the human being's relation to reality as constitutively shaped by speech, and speech not as means of knowing or representing things but as means of establishing relations among speakers. The article then reconstructs an argument central to the New Thinking that begins with the analysis of the structure of speech in order to discover the relations between the human being, the world, and God that are the conditions without which speech would not accomplish what it always already accomplishes, namely, to establish relations among speakers. The idea that emerges from this analysis is that prior to, and presupposed by, our capacity to know reality objectively, our very encounter with reality in speech and time is inescapably a response to God's address. For the New Thinking, God is not an object of knowledge or experience, but the perpetual address that is the condition of speech.

Monitoring the neural activity associated with praying in Sahaja Yoga meditation.

Sahaja Yoga Meditation draws on many religious traditions and uses a variety of techniques including Christian prayer to reach a state known as thoughtless awareness, or mental silence. While there are many studies on the neural correlates of meditation, few studies have focused on the neural correlates of praying. Thus, the aim of our research was to study the neural activity associated with the prayer practices in Sahaja Yoga Mediation, which have not been studied before, to explore effects beyond repetitive speech or "mantra effects". Sixteen experienced Sahaja Yoga Meditation practitioners were scanned using task based functional Magnetic Resonance Imaging while performing formalised and improvised forms of praying and their equivalent secular tasks. Our results showed the deactivation of bilateral thalamus during both prayers compared to secular conditions and the activation in the medial prefrontal cortex that was reduced by religious and formalised secular speech conditions but increased during improvised secular speech; similarly, frontal regions were deactivated when comparing prayers to their secular equivalents. These results seem to depict two important factors related with praying in Sahaja Yoga Meditation merging inner concentration and social cognition. First, the perception of the surroundings mediated by the thalamus may be decreased during these prayers probably due to the establishment of inner concentration and, second, frontal deactivation effects could be related to reduced social judgement and 'mentalizing', particularly in the medial prefrontal cortex. Our findings suggest that praying by Sahaja Yoga Meditation practitioners is neurophenomenologically different from the social cognitive attempt of praying within Christian praying practices.

Neurophysiological evidence of motor preparation in inner speech and the effect of content predictability.

Self-generated overt actions are preceded by a slow negativity as measured by electroencephalogram, which has been associated with motor preparation. Recent studies have shown that this neural activity is modulated by the predictability of action outcomes. It is unclear whether inner speech is also preceded by a motor-related negativity and influenced by the same factor. In three experiments, we compared the contingent negative variation elicited in a cue paradigm in an active vs. passive condition. In Experiment 1, participants produced an inner phoneme, at which an audible phoneme whose identity was unpredictable was concurrently presented. We found that while passive listening elicited a late contingent negative variation, inner speech production generated a more negative late contingent negative variation. In Experiment 2, the same pattern of results was found when participants were instead asked to overtly vocalize the phoneme. In Experiment 3, the identity of the audible phoneme was made predictable by establishing probabilistic expectations. We observed a smaller late contingent negative variation in the inner speech condition when the identity of the audible phoneme was predictable, but not in the passive condition. These findings suggest that inner speech is associated with motor preparatory activity that may also represent the predicted action-effects of covert actions.
