  1. 1. Affective language processing. Modulations of event-related potentials amplitude by induced mood in a valence judgment task

    Master-uppsats, Lunds universitet/Allmän språkvetenskap; Lunds universitet/Masterprogram: Språk och språkvetenskap

    Författare :Ekaterina Kopaeva; [2023]
    Nyckelord :affective processing; emotion; ERP; lexico-semantic processing; mood; valence; Languages and Literatures;

    Sammanfattning : Emotional vocabulary enjoys a processing advantage, with the emotional salience of a word detected at 200 ms post-presentation or earlier, signalling selective attention to its affective properties. An individual’s affective state also impacts attention and, by extension, affects processing. LÄS MER

  3. 2. Word-form recognition in 6-month-olds? Using event-related potentials to study the influence of infant-directed speech

    Master-uppsats, Stockholms universitet/Institutionen för lingvistik

    Författare :Bente Sand Aronsson; [2023]
    Nyckelord :Word-form recognition; event-related potentials; infant-directed speech; language acquisition; Igenkänning av ordformer; event-relaterade potentialer; barnriktat tal; språkinlärning;

    Sammanfattning : By 4.5 months infants listen longer to their names compared to matched foils, which is the earliest empirically demonstrated sign of word-form recognition. This ability develops gradually in the first year of life and becomes increasingly advanced. LÄS MER

  4. 3. The role of word accents in semantic processing in South Swedish

    Master-uppsats, Lunds universitet/Masterprogram: Språk och språkvetenskap; Lunds universitet/Fonetik

    Författare :Jinhee Kwon; [2023]
    Nyckelord :Word accents; spoken word recognition; prediction; ERP; N400; Languages and Literatures;

    Sammanfattning : Prosodic cues can aid speech processing by adding semantic information in lexical tones or functional information in intonational tones. Swedish word accents are considered to have stronger grammatical functions than semantic roles, although they are shaped by both lexical and intonational information structure. LÄS MER

  5. 4. ERP and MEG Correlates of Visual Consciousness : An Update

    Magister-uppsats, Högskolan i Skövde/Institutionen för biovetenskap

    Författare :Jona Förster; [2019]
    Nyckelord :Neural correlates of consciousness; Event-related potentials; Event-related fields; Visual awareness negativity; Late positivity; Global Neuronal Workspace theory; Recurrent Processing theory;

    Sammanfattning : Two decades of event-related potential (ERP) research have established that the most consistent correlates of the onset of visual consciousness are the early visual awareness negativity (VAN), a negative component in the N2 time range over posterior electrode sites, and the late positivity (LP), a positive component in the P3 time range over fronto-parietal electrode sites. A review by Koivisto & Revonsuo (2010) had looked at 39 studies and concluded that the VAN is the earliest and most reliable correlate of visual phenomenal consciousness, whereas the LP probably reflects later processes associated with reflective/access consciousness.

  7. 5. Evaluation of cognitive workload using EEG : Investigation of how sensory feedback improves function of osseo-neuromuscular upper limb prostheses

    Master-uppsats, Linköpings universitet/Institutionen för medicinsk teknik

    Författare :Linn Berntsson; [2019]
    Nyckelord :EEG; ERP; spectral analysis; cognitive workload; prosthesis;

    Sammanfattning : The e-OPRA Implant System (Integrum AB, Sweden) is a system which employs permanently accessible implantable neuromuscular electrodes in combination with osseointegrated attachment of the prosthesis to the skeleton, in order to create a more natural control of advanced robotic upper-limb prostheses. The system enables the possibility of sensory feedback, via a cuff electrode to the ulnar nerve which allows for direct neurostimulation of the nerve. LÄS MER
