  1. 1. The neural substrates of non-conscious working memory

    Författare :Fredrik Bergström; Johan Eriksson; Lars Nyberg; René Marois; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; non-conscious; working memory; neural substrates; visual perception; consciousness; functional magnetic resonance imaging fMRI ;

    Sammanfattning : Background: Despite our distinct impression to the contrary, we are only conscious of a fraction of all the neural activity underlying our thoughts and behavior. Most neural processes occur non-consciously, and in parallel with our conscious experience. LÄS MER

  3. 2. 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; []

    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

  4. 3. 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. 4. Does It Pay to Practice? : A Quasi-Experimental Study on Working Memory Training and Its Effects on Reading and Basic Number Skills

    Författare :Karin I. E. Dahlin; Mara Westling Allodi; Mats Myrberg; Linda Siegel; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Working memory training; attention deficits; special educational needs; reading; basic mathematics; computer assisted instruction; specialpedagogik; Special Education;

    Sammanfattning : This dissertation is based on results from an intervention study targeting working memory training. A group of 46 boys and 11 girls (aged 10.7) that were attending special units in 16 regular schools participated in the study. LÄS MER

  7. 5. Neural mechanisms underlying working memory : computational and neuroimaging studies

    Författare :Julian Macoveanu; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The performance on various cognitive tasks, from language to selective attention and guidance of future actions depends on working memory (WM), the ability to hold and manipulate limited items of information for a period of up to a few seconds. During childhood development, WM capacity, the number of items one can maintain in WM, increases. LÄS MER
