Time-Dependent Correlation and Response Functions
2014
The dynamics of liquids is discussed with the help of time-dependent correlation functions. They are related to response functions by the fluctuation-dissipation theorem. This theorem enables to relate experimentally measured inelastic scattering data to the Fourier-transformed correlation and response functions. The Laplace transform of the correlation functions can be represented as a continuous fraction with suitable residual terms (memory functions). The projection formalism of Mori and Zwanzig is introduced.
Brain Research Reveals Automatic Musical Memory Functions in Children
2009
Even though music has special meanings and values compared to other sounds, it is nonetheless processed in the brain via partly the same neural networks that are built to process all kinds of sounds. The development of these brain areas depends on the input: on the sounds that a child is exposed to and chooses to attend to. We present two brain research paradigms that can be used to assess the specialization of the brain for musical sounds, and show promising results with these paradigms in a group of young children who have music as their hobby.
A Guide to Designing a Memory fMRI Paradigm for Pre-surgical Evaluation in Temporal Lobe Epilepsy
2020
There has been increasing interest in the clinical and experimental use of memory functional Magnetic Resonance Imaging (fMRI). The 2017 American Academy of Neurology practice guidelines on the use of pre-surgical cognitive fMRI suggests that verbal memory fMRI could be used to lateralize memory functions in people with Temporal Lobe Epilepsy (TLE) and should be used to predict post-operative verbal memory outcome. There are however technical and methodological considerations, to optimize both the sensitivity and specificity of this imaging modality. Below we discuss these constraints and suggest recommendations to consider when designing a memory fMRI paradigm.
Rajallinen työmuisti S2-oppijoiden puheenymmärtämisvaikeuksien selittäjänä
2019
Tässä artikkelissa käsittelen työmuistin rajallisuuden ja aikuisten suomenoppijoiden puheenymmärtämisvaikeuksien yhteyttä tarkastelemalla oppijoiden kuuntelutehtäväsuorituksia ja niitä seuraavia stimulated recall -haastatteluja. Lisäksi selvitän, millaisilla muistitoiminnoilla oppijat kompensoivat työmuistin rajallisuutta ja helpottavat ymmärtämistä. Tutkimukseen osallistui 12 arabiankielistä alkeis- ja perustason aikuista suomenoppijaa, ja aineisto koostuu oppijoiden kuuntelutehtäväsuoritusten ja stimulated recall -haastattelujen videotallenteista. Työmuistin rajallisuuden vaikutus ymmärtämisvaikeuksissa tuli esiin erityisesti silloin, kun yhteen sanaan tai ilmaukseen keskittyminen aiheutt…
