  1. 1. Examining the Interaction Effects of Fluid Intelligence, Visual Cue Reliance, and Hearing Aid Usage on Speech-in-Noise Recognition Abilities : An investigative study in hearing aid users

    Kandidat-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Tnbit Isayas Ghebregziabiher; [2023]
    Nyckelord :speech-in-noise recognition; hearing aid; fluid intelligence; visual cues; cognition; hearing;

    Sammanfattning : Research within cognitive hearing science has throughout the years examined the relationship between speech recognition and cognitive functioning. The purpose of this study was to examine the effects of hearing aid experience, fluid intelligence, and visual cues on speech-in-noise recognition. Data from the n200 database by Rönnberg et al.

  3. 2. The association between cognition and speech-in-noise perception : Investigating the link between speech-in-noise perception and fluid intelligence in people with and without hearing loss

    Kandidat-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Simon Dahlgren; [2020]
    Nyckelord :cognition; speech-in-noise; fluid intelligence; Raven’s Progressive Matrices; hearing loss;

    Sammanfattning : The link between speech-in-noise recognition and cognition has been researched extensively over the years, and the purpose of this thesis was to add to this field. Data from a sample of 394 participants from the n200 database (Rönnberg et al. LÄS MER

  4. 3. Passive Radar Detection of Aerial Targets

    M1-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Andreas Örstadius; Erol Ali; [2017]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The purpose of this thesis is to construct a passive bistatic radar system using two USRP N200 software defined radios and two ordinary TV-antennas. Several auxiliary components were used in order to align and calibrate the devices including an octoclock CDA-2990, switch and signal generator. LÄS MER

  5. 4. Etnisk in-gruppsfavorisering vid semantisk priming av ansikten: en empirisk studie av dess ERP-korrelat hos svenska studenter

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för psykologi

    Författare :Daniel Wallin; [2013]
    Nyckelord :automatiska attityder; automatic attitudes; implicita attityder; implicit attitudes; etniska fördomar; ethnic prejudge; etniska stereotyper; ethnic stereotypes; etniska attityder; ethnic attitudes; N400; P200; N200; priming; in-grupp; in-group; ut-grupp; out-group; Social Sciences;

    Sammanfattning : Many studies have been conducted investigating automatically activated attitudes towards ethnic groups, where the main measure has been reaction time. Mainly, these studies have looked at relative preferences for ethnic in-groups over ethnic out-groups. LÄS MER

  7. 5. Localization of Brain Activity in Electroencephalography Data during Brain-Computer Interface Operation

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Oskar Hjärtquist; [2011]
    Nyckelord :P300 ; N200; Event-related potential ERP; Noise Subspace Fitting NSF ; Null Space Projection NP ; Localization; Dipole source; Elec- troencephalography EEG ; Brain-Computer Interface BCI Speller; Technology and Engineering;

    Sammanfattning : In this Master's thesis I present a means of finding active sources of cortical electrical activity from electroencephalogram (EEG) data acquired during operation of a brain-computer interface (BCI). A novel subspace-based technique was used to suppress spatially correlated EEG interference sources, followed by a technique that estimates the source parameters with a near maximum likelihood performance.
