Enhanced inhibitory control during re-engagement processing in badminton athletes : An event-related potential study
2019
Highlights • Reaction time and event-related potentials of inhibitory control were compared in badminton experts and nonathletes. • Badminton experts showed enhanced inhibitory control and more efficient neural mechanisms. • Badminton experts performed better inhibitory control processing in re-engagement. • The re-engagement processing better demonstrated altered brain activity in badminton experts.
Dissociable Effects of Reward on P300 and EEG Spectra Under Conditions of High vs. Low Vigilance During a Selective Visual Attention Task
2020
The influence of motivation on selective visual attention in states of high vs. low vigilance is poorly understood. To explore the possible differences in the influence of motivation on behavioral performance and neural activity in high and low vigilance levels, we conducted a prolonged 2 h 20 min flanker task and provided monetary rewards during the 20- to 40- and 100- to 120-min intervals of task performance. Both the behavioral and electrophysiological measures were modulated by prolonged task engagement. Moreover, the effect of reward was different in high vs. low vigilance states. The monetary reward increased accuracy and decreased the reaction time (RT) and number of omitted response…

Determination of the Time Window of Event-Related Potential Using Multiple-Set Consensus Clustering
2020
Clustering is a promising tool for grouping the sequence of similar time-points aimed to identify the attention blocks in spatiotemporal event-related potentials (ERPs) analysis. It is most likely to elicit the appropriate time window for ERP of interest if a suitable clustering method is applied to spatiotemporal ERP. However, how to reliably estimate a proper time window from entire individual subjects’ data is still challenging. In this study, we developed a novel multiset consensus clustering method in which several clustering results of multiple subjects were combined to retrieve the best fitted clustering for all the subjects within a group. Then, the obtained clustering was processed…
Uusien 5G-teknologioiden energiatehokkuus
2016
Mobiiliverkkojen datamäärän kasvaessa räjähdysmäisesti tarvitaan uutta 5G-teknologiaa lisäämään langattomien verkkojen kapasiteettia. 5G-verkkoja kehitettäessä yksi tärkeä tutkimuskysymys on, kuinka saada niistä energiatehokkaita. Tässä tutkielmassa käydään läpi tieteellistä keskustelua aiheesta. Tieteellisestä keskustelusta keskeisimmiksi teknologioiksi 5G-verkkoihin nousevat muun muassa laitteistotekniikan kehittyminen, millimetriaallot, kognitiivinen radioverkko, massiivinen MIMO ja heterogeeninen verkko. Tarvitaan kuitenkin lisää tutkimusta ja kehitystyötä, jotta uusista 5G-verkoista saadaan riittävän energiatehokkaita. The amount of mobile data will grow radically and that's why we nee…

Use of Sign Language Videos in EEG and MEG Studies : Experiences from a Multidisciplinary Project Combining Linguistics and Cognitive Neuroscience
2022
In this paper, we describe our experiences of bringing together methodologies of two disciplines – sign language (SL) linguistics and cognitive neuroscience – in the multidisciplinary ShowTell research project (Academy of Finland 2021–2025). More specifically, we discuss the challenges we encountered when creating and using video materials for the study of SL processing in the brain. Rather than using still images, the study of SL comprehension is better performed by using videos, thus providing more naturalistic stimuli as observed in face-to-face interaction. On the other hand, in neuroimaging (electroencephalography [EEG]/magnetoencephalography [MEG]), it is vital to track the timing of …
Hyvän ja pahan rinteillä : tieteen retoriikka ja moraalin metaforiikka Sam Harrisin kirjassa The Moral Landscape: How Science Can Determine Human Val…
2016
Tässä työssä tutkitaan kognitiivisten metaforien rakentumista ja toimintaa. Tutkimuksen pääkohteeksi nousee moraalisen ymmärryksen ja kognitiivisten metaforien suhde hyvinvoinnin käsitteen kautta. Aluksi tutkitaan Sam Harrisin tekstiä sen retorisesta viitekehyksestä käsin. Myöhemmin tutkielmassa metaforan toimintaa ja soveltamisen mahdollisuuksia tarkastellaan laajemmin suomalaisessa kulttuurissa ja mediassa. Tutkielman lähtökohtana on moraalisen ymmärtämisen vaikeus ja halu selvittää, voivatko kognitiiviset metaforat tarjota toimivia työkaluja moraalisen päätöksenteon arvottamiseen ja moraalisten narratiivien tutkimukseen. Tutkielmassa halutaan selvittää onko Harrisin moraalinen maisema -m…
Dissonance and Neutralization of Subscription Streaming Era Digital Music Piracy : An Initial Exploration
2016
Both legal and illegal forms of digital music consumption continue to evolve with wider adoption of subscription streaming services. With this paper, we aim to extend theory on digital music piracy by showing that the rising controversy and diminishing acceptance of illegal forms of consumption call for new theoretical components and interactions. We introduce a model that integrates insights from neutralization and cognitive dissonance theories. As an initial empirical test of the proposed Dissonance-Neutralization model, we estimate a structural equation model based on self-administered survey data obtained from 322 respondents. Our results uncover potential demographic differences in pir…
