The Contribution of Event-Related Potentials to the Understanding of Sign Language Processing and Production in the Brain : Experimental Evidence and…
2022
Functional neuroimaging allows investigation of the timing properties of the brain mechanisms underlying covert language processing. This paper presents a review of the use of the neuroimaging technique called Event-Related Potentials (ERPs) in sign language (SL) research. In the field of neurolinguistics, ERPs have been widely used in the study of spoken language, but their use in SL is still rare. Studying the neurocognitive aspects of SL could lead to a better understanding of the specific processing of SL in the brain. This review outlines the basic theoretical and methodological principles of ERPs. We focus on three groups of ERPs that are particularly relevant to SL processing and pro…
Typical and Atypical Development of Visual Expertise for Print as Indexed by the Visual Word N1 (N170w) : A Systematic Review
2022
The visual word N1 (N170w) is an early brain ERP component that has been found to be a neurophysiological marker for print expertise, which is a prelexical requirement associated with reading development. To date, no other review has assimilated existing research on reading difficulties and atypical development of processes reflected in the N170w response. Hence, this systematic review synthesized results and evaluated neurophysiological and experimental procedures across different studies about visual print expertise in reading development. Literature databases were examined for relevant studies from 1995 to 2020 investigating the N170w response in individuals with or without reading disor…
Somatosensory Deviance Detection ERPs and Their Relationship to Analogous Auditory ERPs and Interoceptive Accuracy
2022
Abstract. Automatic deviance detection has been widely explored in terms of mismatch responses (mismatch negativity or mismatch response) and P3a components of event-related potentials (ERPs) under a predictive coding framework; however, the somatosensory mismatch response has been investigated less often regarding the different types of changes than its auditory counterpart. It is not known whether the deviance detection responses from different modalities correlate, reflecting a general prediction error mechanism of the central nervous system. Furthermore, interoceptive functions have been associated with predictive coding theory, but whether interoceptive accuracy correlates with devian…

Auditory perceptual learning : evidence from electrophysiological recordings in rodents and humans
2018
Yllättävät muutokset äänimaailmassa viestittävät yleensä selviytymisen kannalta tärkeistä vihjeistä, joten niiden nopea ja automaattinen havaitseminen on tärkeää. Tietoinen harjoittelu mahdollistaa havainto-oppimisen ja oppimisen seurauksena hermostoon muodostuu uusia muistijälkiä. Varhaisessa kehityksessä herkkyyskauden aikana muistijälkien muodostuminen, ihmisellä erityisesti puheäänille, on automaattista, eikä siihen vaadita tietoista harjoittelua. Toisaalta perinteisesti on ajateltu, että herkkyyskauden jälkeen vain aktiivinen harjoittelu johtaa uusien muistijälkien muodostumiseen. Muutoksen havaitsemisen hermostollista perustaa voidaan tutkia mittaamalla aivojen sähköisiä jännitevastei…

Emotional modulation of the attentional blink and the relation to interpersonal reactivity
2013
The extent of the attentional blink effect on detection rates in rapid serial visual presentations is modulated by the emotionality of the stimuli. Emotionally salient stimuli are detected more often, even if presented in the attentional blink period, and elicit an enlarged P3 response, which has been interpreted as enhanced consolidation. This effect correlates with individual differences in trait affectivity such as anxiety or dysphoria. Here, we ask if it is also related to the capacity to detect emotions in others, i.e., to interpersonal social traits. We therefore presented emotional and neutral images depicting social scenes as targets in an attentional blink design and measured detec…
Grammar types in language explain tone sequence processing in music
2009
In this ERP study, linear and center-embedded musical sequences are built according to two artificial grammar types in language, named finite state grammar (FSG) and phrase structure grammar (PSG). The aim is to prove if neural sources and processing mechanisms for artificial grammar settings across domains are the same. Isochronous pitch sequences were constructed by two interval categories (3rd and 6th) in upward and downward direction. FSG sequences, which have the general form ABAB in artificial grammar, are translated into “small up/small down/large up/large down”. PSG sequences of form A[AB]B are transposed to “small up/large up/large down/small down”. In two ERP recordings testing FS…
