  1. 1. Mind your Language, All Right? Performance-dependent neural patterns of language

    Författare :Helene van Ettinger-Veenstra; Maria Engström; Peter Lundberg; Thomas Karlsson; Anita McAllister; Karsten Specht; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Language ability; performance; fMRI; functional magnetic resonance imaging; Broca; Wernicke; temporal lobe; inferior frontal gyrus; reading; fluency; lateralization; lateralisation; right hemisphere; performance-dependent; neural activation;

    Sammanfattning : The main aim of this dissertation was to investigate the difference in neural language patternsrelated to language ability in healthy adults. The focus lies on unraveling the contributions of theright‐hemispheric homologues to Broca’s area in the inferior frontal gyrus (IFG) and Wernicke’s areain the posterior temporal and inferior parietal lobes.

  3. 2. Regimented language training : Changes to brain and behaviour following intensive non-native language learning

    Författare :Johan Mårtensson; Institutionen för psykologi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Cortical thickness; Hippocampus; Plasticity; Language acquisition; Associative memory; Transfer; Education;

    Sammanfattning : The influence of foreign-language acquisition on adult brain structure remains mostly unexplored. Whilst several cross-sectional studies have led to further understanding of how language can affect brain structure, only a few longitudinal studies have been conducted. LÄS MER

  4. 3. Interference control in working memory : neurobehavioral properties and age differences

    Författare :George Samrani; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :working memory;

    Sammanfattning : This doctoral thesis aimed to investigate the basic processes of interference control (IC) in working memory (WM). We sought to unravel some of the underlying mechanisms of IC by examining brain correlates, while also trying to understand the differences that arise with advancing adult age. LÄS MER

  5. 4. Brain anatomical correlates of perceptual phonological proficiency and language learning aptitude

    Författare :Mikael Novén; Allmän språkvetenskap; []
    Nyckelord :HUMANIORA; HUMANITIES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Prosody; word accent; MRI; language learning aptitude; cortical morphometry; diffusion kurtosis imaging;

    Sammanfattning : The present dissertation concerns how brain tissue properties reflect proficiency in two aspects of language use: the ability to use tonal cues on word stems to predict how words will end and the aptitude for learning foreign languages. While it is known that people differ in their language abilities and that damage to brain tissue cause loss of cognitive functions, it is largely unknown if differences in language proficiencies correlate with differences in brain structure.

  7. 5. Dealing with Digits : Arithmetic, Memory and Phonology in Deaf Signers

    Författare :Josefine Andin; Mary Rudner; Jerker Rönnberg; Örjan Dahlström; Lars Nyberg; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adult deaf signers; phonology; arithmetic; short-term memory; working memory; neuro imaging; Vuxna teckenspråkiga döva; fonologi; aritmetik; korttidsminne; arbetsminne; hjärnavbildning;

    Sammanfattning : Deafness has been associated with poor abilities to deal with digits in the context of arithmetic and memory, and language modality-specific differences in the phonological similarity of digits have been shown to influence short-term memory (STM). Therefore, the overall aim of the present thesis was to find out whether language modality-specific differences in phonological processing between sign and speech can explain why deaf signers perform at lower levels than hearing peers when dealing with digits.
