- Sound frequencies are represented in the primary auditory cortex (PAC) in a tonotopic structure which can be measured using functional magnetic resonance imaging (fMRI). A previous study has investigated vowels[ъ]and [i]and seen a correlation between the vowels¶ activation and the activation of simple tones corresponding to the vowels¶ formant frequencies. Other vowels have not \et been studied. In this study, we are investigating [ъ],[ѓ], [i], and [u]and compared those with activation of simple tones corresponding to their formant frequencies. This is ongoing work, and only five volunteers have participated. The preliminary results vary from high correlation between areas activated to low or no correlation. More data has to be collected to draw any further conclusions.

Phonemic and subphonemic cues in prediction : Evidence from ERP, eye-tracking and Danish words with and without stødbasis
- 2021
-
Ingår i: Proceedings of Fonetik 2021 : Lund, June 8–9, 2021 - Lund, June 8–9, 2021. - 0280-526X. ; 56, s. 27-32

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- The brain is constantly trying to predict the future and phonological and prosodic cues are used to anticipate forthcoming information. Even cues on the subphonemic level such as vowel transitions, nasalisation and assimilation across word boundaries are useful in anticipating upcoming speech. In event-related potential (ERP) studies examining subphonemic and lexical/phonological mismatches, only the latter yielded N400 effects, an ERP component associated with lexical prediction error. The results indicate that phonetic cues are resolved prelexically. However, subphonemic cues still seem to be used in prediction as evidenced by valid cues yielding faster fixations in eye-tracking studies and invalid cues modulating P600 amplitudes, indicating structural violations and context updating.

- The N400 has been seen to be larger for concrete than abstract words, and for pseudowords than real words. Using a word vector analysis to calculate semantic associates (SA), as well as ratings for emotional arousal (EA), and a measure of orthographic neighbourhood (ON), the present study investigated the relation between these factors and N400 amplitudes during a lexical decision task using Swedish word stimuli. Four noun categories differing in concreteness: specific (squirrel), GENERAL (animal) emotional (happiness) and abstract (tendency) were compared with pseudowords (danalod). Results showed that N400 amplitudes increased in the order emotional < abstract < GENERAL < specific < PSEUDOWORD. A regression analysis showed that the amplitude of the N400 decreased the more semantic associates a word had and the higher the rating for emotional arousal it had. The N400 also increased the more orthographic neighbours a word had. Results provide support for the hierarchical organisation of concrete words assumed in lexical semantics. They also demonstrate how affective information facilitates meaning processing.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Acoustic discrimination of speech sounds is affected by various factors, ranging from more universal acoustic properties of categories to the phoneme systems of the native language and dialect, and even influences from languages learned later in life. A discrimination experiment containing East Central Swedish vowels was carried out with 30 native Swedish listeners in order to explore the variation in vowel discrimination performance. Both phonetic and phonological variables have been found to have an effect on discrimination performance. Peripheral location of vowels in the F1/F2 vowel space was found to increase the discrimination performance. South Swedish dialectal area was associated with a decreased discrimination performance. Continuous exposure to foreign languages otherthan English was not a significant factor.

The predictive function of Swedish word accents
- 2022

Ingår i: Frontiers in Psychology. - : Frontiers Media SA. - 1664-1078. ; 13, s. 1-11
-
Tidskriftsartikel (refereegranskat)abstract
- Swedish lexical word accents have been repeatedly said to have a lowfunctional load. Even so, the language has kept these tones ever sincethey emerged probably over a thousand years ago. This article proposesthat the primary function of word accents is for listeners to be ableto predict upcoming morphological structures and narrow down thelexical competition rather than being lexically distinctive. Psycho- andneurophysiological evidence for the predictive function of word accents isdiscussed. A novel analysis displays that word accents have a facilitativerole in word processing. Specifically, a correlation is revealed betweenhow much incorrect word accents hinder listeners’ processing and howmuch they reduce response times when correct. Finally, a dual-route modelof the predictive use of word accents with distinct neural substrates isput forth.

The use of lexical tone in the segmentation of speech
- 2023
-
Ingår i: ; , s. 70-71
-
Konferensbidrag (refereegranskat)abstract
- IntroductionIn speech, there are no blank spaces to signal boundaries between words as there is in written language, but listeners can nevertheless recognise individual words rapidly. Without these blank spaces or commas, listeners have to divide up – segment – the continuous speech stream into discrete words using other means. This study aimed to investigate the tonal cues important for speech segmentation in Swedish. We know that that different languages use different cues in speech segmentation, such as stress (Norris, McQueen, & Cutler, 1995), syllable weight (Cutler & Norris, 1988) and vowel harmony (Suomi, McQueen, & Cutler, 1997), but we do not yet know the extent to which phonological cues are used in speech segmentation. In English, stressed and metrically strong syllables are heard as more reliable word onsets, leading the parser to initiate a lexical access attempt at these points. Accurate segmentation is crucial since words can always be embedded in larger words, and these spurious embedded words are activated in memory (Luce & Cluff, 1998): the phrase start writing potentially includes star, trite, try, rye and so on (Cutler, 2012). However, no study has yet investigated speech segmentation in languages like Swedish, where prosody systematically combines with morphology. This will allow us to more fully understand universal drivers behind speech segmentation.In Swedish, every word or word stem has a lexical tone known as a word accent, in addition to stress. In Central Swedish, this tone is either low (accent 1) or high (accent 2). All monosyllabic words have accent 1, and the majority of polysyllabic words – such as compounds – have accent 2 on the word stem, especially trochees. There is also an interaction between prosody and morphology, so that stem word accent is also determined by suffixation: the word stem båt (‘boat’) has accent 1 preceding the singular suffix -en (båt1-en) but accent 2 preceding the plural suffix -ar (båt2-ar). With regard to word embeddings, a frequent accent 2 word with a plural suffix like möten2 (‘meetings’) potentially contains mö (‘maiden’) and tenn (‘tin’), and the accent 2 on the word stem ensures it can also be heard as the compound mö-tenn (‘maiden tin’). However, the string möten1 with accent 1 can only be heard as two words, as in the phrase möt en ko (‘meet a cow’). Accent 2 has thus been proposed to be ‘connective’ (Elert, 1970; Malmberg, 1959): it signals that more syllables will follow, belonging to the same lexical item. A string with accent 2 can thus always contain other words, perhaps more so than accent 1, which might make it more difficult to segment – especially in the case of monosyllabic targets – than accent 1 strings.This study used a word spotting paradigm to investigate the segmentation of Swedish words embedded in non-word frames to determine how prosody and syllable structure interact to affect word spotting performance.MethodsNative speakers of Swedish listened to auditory stimuli – trisyllabic non-word frames – recorded by a native speaker of Central Swedish. They were asked to press a button when they heard a Swedish word at the beginning of a string, entering the word using the computer keyboard. Each participant heard 15 monosyllabic target words embedded in accent 1 frames (bal-ädi1 ‘ball’), 15 monosyllabic words in accent 2 frames (bal-ädi2), 15 disyllabic words in accent 2 frames (bagge-pi2 ‘ram’) and 15 disyllabic words in accent 1 frames (bagge-pi1). All target items were matched for word frequency. Word accent pairs were counterbalanced across subjects. There were 60 fillers, containing no possible Swedish words. For response times, only trials where participants spotted and typed in the correct word were included, whereas all trials were included in the accuracy analysis.Data analysis and resultsResponse times were analysed using a generalised linear mixed-effects model with an inverse Gaussian function and identity link using the lme4 package in R (Bates, Mächler, Bolker, & Walker, 2015). Word accent and number of target syllables were included as deviation-coded fixed effects with participant and item as random effects. The fastest response times were found for disyllabic words (e.g. bagge) in accent 2 frames, significantly faster than for monosyllabic words (e.g. bal) in accent 2 frames. Response accuracy was analysed using an identical model structure to response times but using a binomial function and logit link. An interaction between accent and number of target syllables showed that disyllabic words were spotted more successfully than monosyllabic words in accent 2 frames. DiscussionMonosyllabic targets were more difficult to spot in accent 2 strings, as shown by both response time and accuracy. This can possibly be explained by the fact that accent 2 strings can always contain other words, slowing down speech segmentation and recognition. It is also possible that the word accent triggers inappropriate syllabification, so that bal in bal-ädi2 is heard as the non-word ba (*ba-lädi), similarly to strong syllables signalling a segmentation point and prompting syllabification in English (Cutler & Norris, 1988).ReferencesBates, D., Mächler, M., Bolker, B., & Walker, S.

Pre-activation negativity (PrAN) : A neural index of predictive strength of phonological cues
- 2023
-
Ingår i: Laboratory Phonology. - : Open Library of the Humanities. - 1868-6354. ; 14:1, s. 1-28
-
Tidskriftsartikel (refereegranskat)abstract
- We propose that a recently discovered event-related potential (ERP) component—the pre-activation negativity (PrAN)—indexes the predictive strength of phonological cues, including segments, word tones, and sentence-level tones. Specifically, we argue that PrAN is a reflection of the brain’s anticipation of upcoming speech (segments, morphemes, words, and syntactic structures). Findings from a long series of neurolinguistic studies indicate that the effect can be divided into two time windows with different possible brain sources. Between 136 and 200 ms from stimulus onset, it indexes activity mainly in the primary and secondary auditory cortices, reflecting disinhibition of neurons sensitive to the expected acoustic signal, as indicated by the brain regions’ response to predictive certainty rather than sound salience. After ~200 ms, PrAN is related to activity in Broca’s area, possibly reflecting inhibition of irrelevant segments, morphemes, words, and syntactic structures.

Tidskriftsartikel (refereegranskat)abstract
- Background and purpose. Whereas traditional views of language processing in the brain have assumed that the language function is concentrated to a limited number of cortical areas (Broca’s and Wernicke’s areas), current knowledge points at a much more complex system of language and speech processing involving many brain areas, both cortical and subcortical. The purpose of the current study was to make an unbiased assessment of which cerebral areas are affected in first-ever acute ischemic stroke patients identified as having language and speech impairments according to the National Institute of Health Stroke Scale (NIHSS). Methods. Data from thirty-four patients with language and speech impairments, with a score of 1-3 on item 9 on the NIHSS, following ischemic stroke was collected from the Lund Stroke Register. MRI images acquired up to 20 days after stroke onset were used to create an overlap lesion image using MRIcron software. Results. The classical language areas, Wernicke’s and Broca’s area, were affected in less than one fourth of the patients. The most frequently affected region was a subcortical region - the left caudate nucleus and the adjacent corona radiata. Conclusions. These findings contribute to the growing body of evidence that the basal ganglia have a crucial role in the control over language and speech processing.

Different neural mechanisms for rapid acquisition of words with grammatical tone in learners from tonal and non-tonal backgrounds : ERP evidence
- 2020
-
Ingår i: Brain Research. - : Elsevier BV. - 0006-8993. ; 1729
-
Tidskriftsartikel (refereegranskat)abstract
- Initial second language acquisition proceeds surprisingly quickly. Foreign words can sometimes be used within minutes after the first exposure. Yet, it is unclear whether such rapid learning also takes place for more complex, multi-layered properties like words with complex morphosyntax and/or tonal features, and whether it is influenced by transfer from the learners’ native language. To address these questions, we recorded tonal and non-tonal learners’ brain responses while they acquired novel tonal words with grammatical gender and number on two consecutive days. Comparing the novel words to repeated but non-taught pseudoword controls, we found that tonal learners demonstrated a full range of early and late event-related potentials in novel tonal word processing: an early word recognition component (~50 ms), an early left anterior negativity (ELAN), a left anterior negativity (LAN), and a P600. Non-tonal learners exhibited mainly late processing when accessing the meaning of the tonal words: a P600, as well as a LAN after an overnight consolidation. Yet, this group displayed correlations between pitch perception abilities and ELAN, and between acquisition accuracy and LAN, suggesting that certain features may lead to facilitated processing of tonal words in non-tonal learners. Furthermore, the two groups displayed indistinguishable performance at the behavioural level, clearly suggesting that the same learning outcome may be achieved through at least partially different neural mechanisms. Overall, the results suggest that it is possible to rapidly acquire words with grammatical tone and that transfer plays an important role even in very early second language acquisition.

Neurophysiological signatures of prediction in language : A critical review of anticipatory negativities
- 2024
-
Ingår i: Neuroscience and Biobehavioral Reviews. - 0149-7634. ; 160
-
Tidskriftsartikel (refereegranskat)abstract
- Recent event-related potential (ERP) studies in language comprehension converge in finding anticipatory negativities preceding words or word segments that can be pre-activated based on either sentence contexts or phonological cues. We review these findings from different paradigms in the light of evidence from other cognitive domains in which slow negative potentials have long been associated with anticipatory processes and discuss their potential underlying mechanisms. We propose that this family of anticipatory negativities captures common mechanisms associated with the pre-activation of linguistic information both within words and within sentences. Future studies could utilize these anticipatory negativities in combination with other, well-established ERPs, to simultaneously track prediction-related processes emerging at different time intervals (before and after the perception of pre-activated input) and with distinct time courses (shorter-lived and longer-lived cognitive operations).

- The present study investigated hierarchical lexical semantic structure in oral descriptions of concrete word meanings produced by a subject (ZZ) diagnosed with anomic aphasia due to left occipital lesions. The focus of the analysis was production of a) nouns at different levels of semantic specificity (e.g., "robin"-"bird"-"animal") and b) words describing sensory or motor experiences (e.g., "blue," "soft," "fly"). Results show that in contrast to healthy and aphasic controls, who produced words at all levels of specificity and mainly vision-related sensory information, ZZ produced almost exclusively nouns at the most non-specific levels and words associated with sound and movement.

Cortical thickness of Broca's area and right homologue is related to grammar learning aptitude and pitch discrimination proficiency
- 2019

-
Tidskriftsartikel (refereegranskat)abstract
- Aptitude for and proficiency in acquiring new languages varies in the human population but their neural bases are largely unknown. We investigated the influence of cortical thickness on language learning predictors measured by the LLAMA tests and a pitch-change discrimination test. The LLAMA tests are first language-independent assessments of language learning aptitude for vocabulary, phonetic working memory, sound-symbol correspondence (not used in this study), and grammatical inferencing. Pitch perception proficiency is known to predict aptitude for learning new phonology. Results show a correlation between scores in a grammatical meaning-inferencing aptitude test and cortical thickness of Broca's area (r(30) = 0.65, p = 0.0202) and other frontal areas (r(30) = 0.66, p = 0.0137). Further, a correlation was found between proficiency in discriminating pitch-change direction and cortical thickness of the right Broca homologue (r(30) = 0.57, p = 0.0006). However, no correlations were found for aptitude for vocabulary learning or phonetic working memory. Results contribute to locating cortical regions important for language-learning aptitude.

A neurolinguistic study of South Swedish word accents : Electrical brain potentials in nouns and verbs
- 2015
-
Ingår i: Nordic Journal of Linguistics. - 0332-5865. ; 38:2, s. 149-162
-
Tidskriftsartikel (refereegranskat)abstract
- The brain response to words with correct and incorrect word accent–suffix combinations in South Swedish was investigated using electroencephalography (EEG). Accent 1 yielded an increased brain response (‘preactivation negativity’) that has previously been interpreted as reflecting preactivation of suffixes. Preactivation is greater for accent 1 due to its association with a limited set of suffixes, whereas accent 2 is default for compound words. The tonal realization of the word accent opposition in South Swedish is practically the mirror image of that in Central Swedish, where a similar preactivation negativity has been found. Therefore, the brain response is unlikely to result from a difference in acoustic features between the word accents. Invalidly cued suffixes yielded brain response pattern showing increased processing load of the unexpected suffix (negative electric potential) followed by its reprocessing (positivity ‘P600’).

- Introduction Left frontal brain lesions are known to give rise to aphasia and impaired word associations. These associations have previously been difficult to analyze. We used a semantic space method to investigate associations to cue words. The degree of abstractness of the generated words and semantic similarity to the cue words were measured. Method Three subjects diagnosed with Broca’s aphasia and twelve control subjects associated freely to cue words. Results were evaluated with latent semantic analysis (LSA) applied to the Swedish Parole corpus. Results The aphasic subjects could be clearly distinguished from controls by a lower degree of abstractness in the words they generated. The aphasic group’s associations showed a negative correlation between semantic similarity to cue word and abstractness of cue word. Conclusions By developing novel semantic measures, we showed that Broca’s aphasic subjects’ word production was characterized by a low degree of abstractness and low degree of coherence in associations to abstract cue words. The results support models where meanings of concrete words are represented in neural networks involving perceptual and motor areas, whereas the meaning of abstract words is more dependent on connections to other word forms in the left frontal region. Semantic spaces can be used in future developments of evaluative tools for both diagnosis and research purposes.

Word tones cueing morphosyntactic structure: Neuroanatomical substrates and activation time-course assessed by EEG and fMRI.

Tidskriftsartikel (refereegranskat)abstract
- Previous studies distinguish between right hemisphere-dominant processing of prosodic/tonal information and left-hemispheric modulation of grammatical information as well as lexical tones. Swedish word accents offer a prime testing ground to better understand this division. Although similar to lexical tones, word accents are determined by words' morphosyntactic structure, which enables listeners to use the tone at the beginning of a word to predict its grammatical ending. We recorded electrophysiological and hemodynamic brain responses to words where stem tones matched or mismatched inflectional suffixes. Tones produced brain potential effects after 136ms, correlating with subject variability in average BOLD in left primary auditory cortex, superior temporal gyrus, and inferior frontal gyrus. Invalidly cued suffixes activated the left inferior parietal lobe, arguably reflecting increased processing cost of their meaning. Thus, interaction of word accent tones with grammatical morphology yielded a rapid neural response correlating in subject variability with activations in predominantly left-hemispheric brain areas.

Pre-activation negativity (PrAN) in brain potentials to unfolding words

Ingår i: Frontiers in Human Neuroscience. - : Frontiers Media SA. - 1662-5161. ; 10:512
-
Tidskriftsartikel (refereegranskat)abstract
- We describe an ERP effect termed the ‘pre-activation negativity’ (PrAN), which is proposed to index the degree of pre-activation of upcoming word-internal morphemes in speech processing. Using lexical competition measures based on word-initial speech fragments (WIFs), as well as statistical analyses of ERP data from three experiments, it is shown that the PrAN is sensitive to lexical competition and that it reflects the degree of predictive certainty: the negativity is larger when there are fewer upcoming lexical competitors.

- Listeners are constantly trying to predict what the speaker will say next. We concurrently measured the electrophysiological and haemodynamic correlates of syntactic pre-activation, investigating when and where the brain processes speech melody cues to upcoming word order structure. Pre-activation of syntactic structure was reflected in a left-lateralised pre-activation negativity (PrAN), which was subserved by Broca’s area in the left inferior frontal gyrus, as well as the contiguous left anterior insula.

Stem tones pre-activate suffixes in the brain

Tidskriftsartikel (refereegranskat)abstract
- Results from the present event-related potentials (ERP) study show that tones on Swedish word stems can rapidly pre-activate upcoming suffixes, even when the word stem does not carry any lexical meaning. Results also show that listeners are able to rapidly restore suffixes which are replaced with a cough. Accuracy in restoring suffixes correlated positively with the amplitude of an anterior negative ERP elicited by stem tones. This effect is proposed to reflect suffix pre-activation. Suffixes that were cued by an incorrect tone elicited a left-anterior negativity and a P600, suggesting that the correct processing of the suffix is crucially tied to the activation of the preceding validly associated tone.

Words and their meaning: a deep delve from surface distribution into underlying neural representation
- 2010
-
Proceedings (redaktörskap) (refereegranskat)abstract
- This special issue of The Mental Lexicon contains a number of papers presented at a symposium at the Center for Languages and Literature, Lund University, on December 10, 2009. The interdisciplinary meeting brought together researchers from linguistics, psychology, and neuroscience in order to discuss different approaches to studying the complexities surrounding the modelling of word semantics. The goal was to obtain a better understanding of the relationship between the linguistic modelling of the lexicon and neurocognitive and neurophysiological representations and processes related to word meaning. The papers cover both theoretical aspects of word meaning seen from the perspective of linguists (Jean Aitchison, Michael Fortescue) and neuropsychologists (Allan Paivio) as well as experimental studies by neuroscientists investigating different aspects of meaning structure using different brain imaging techniques (Véronique Boulenger & Tatjana Nazir, Yury Shtyrov).
