  1. 16. Modalities of Mind : Modality-specific and nonmodality-specific aspects of working memory for sign and speech

    Författare :Mary Rudner; Jerker Rönnberg; Alan Baddeley; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cognition; sign language; working memory; fMRI; PET; disability research; Korttidsminne; teckenspråk; Cognitive science; Kognitionsvetenskap;

    Sammanfattning : Language processing is underpinned by working memory and while working memory for signed languages has been shown to display some of the characteristics of working memory for speech-based languages, there are a range of anomalous effects related to the inherently visuospatial modality of signed languages. On the basis of these effects, four research questions were addressed in a series of studies:1. LÄS MER

  3. 17. Active Memory Processing on Multiple Time-scales in Simulated Cortical Networks with Hebbian Plasticity

    Författare :Florian Fiebig; Anders Lansner; Tim Vogels; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Working memory; Long-term memory; consolidation; spiking; neural network; BCPNN; cortical microcircuit; Tillämpad matematik och beräkningsmatematik; Applied and Computational Mathematics; Biological Physics; Biologisk fysik;

    Sammanfattning : This thesis examines declarative memory function, and its underlying neural activity and mechanisms in simulated cortical networks. The included simulation models utilize and synthesize proposed universal computational principles of the brain, such as the modularity of cortical circuit organization, attractor network theory, and Hebbian synaptic plasticity, along with selected biophysical detail from the involved brain areas to implement functional models of known cortical memory systems.

  4. 18. Working memory : development, disorders and training

    Författare :Helena Westerberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Working memory; Functional magnetic resonance imaging; Human development; Children; ADHD; Stroke; Brain injury; Intervention; Training; Visuo-spatial span; Choice Reaction Time; Attention;

    Sammanfattning : Working memory (WM) is the ability to keep information online during a short period of time. Brain regions underlying WM functioning are found in the frontal and parietal cortices. It is largely unknown to what extent the neural substrates underlying WM are susceptible to training induced change. LÄS MER

  5. 19. Lost in Translation : Speech recognition and memory processes in native and non-native language perception

    Författare :Lisa Kilman; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Speech perception; perceived disturbance; native; non-native; working memory; language proficiency; episodic long-term memory; Taluppfattning; upplevd störning; modersmål; ett andra språk; arbetsminne; språkfärdigheter; episodiskt långtids-minne;

    Sammanfattning : This thesis employed an integrated approach and investigated intra- and inter-individual differences relevant for normally hearing (NH) and hearing-impaired (HI) adults in native (Swedish) and non-native (English) languages in adverse listening conditions. The integrated approach encompassed the role of cognition as a focal point of interest as well as perceptualauditory and linguistic factors. LÄS MER
