Kuulohavainnon muutoksen vaikutus saksofonistin intonaation tarkkuuteen

2015

Kuulohavainnon avulla erotellaan äänestä eri ominaisuuksia, kuten äänenkorkeutta, -voimakkuutta ja -kirkkautta. Tarkka intonaatio esimerkiksi saksofonia soitettaessa vaatii hyvää ja selkeää auditiivista palautetta, sekä äänenkorkeuden erotus- ja kohdistuskykyä. Erilaiset soittotilanteet, akustiset olosuhteet, sekä korvatulppien käyttö aiheuttavat muutoksia kuulokuvaan. Järjestettiin koe, jossa seitsemän alttosaksofonistia soitti kolmea erityyppistä lyhyttä melodiaa: pitkiä ääniä, melodioita ja intervallihyppyjä. Soitettavat melodiat äänitettiin, sekä toistettiin kuulonsuojauksella ja ilman. Äänidatasta poimittiin kolmea kohdeääntä, joista analysoitiin äänenkorkeus, äänenvoimakkuus ja äänenv…

Analysis of Somatosensory Cortical Responses to Different Electrotactile Stimulations as a Method Towards an Objective Definition of Artificial Senso…

2022

Sensory feedback is a critical component in many human-machine interfaces (e.g., bionic limbs) to provide missing sensations. Specifically, electrotactile stimulation is a popular feedback modality able to evoke configurable sensations by modulating pulse amplitude, duration, and frequency of the applied stimuli. However, these sensations coded by electrotactile parameters are thus far predominantly determined by subjective user reports, which leads to heterogeneous and unstable feedback delivery. Thus, a more objective understanding of the impact that different stimulation parameters induce in the brain, is needed. Analysis of cortical responses to electrotactile afference might be an effe…

Decoding attentional states for neurofeedback : Mindfulness vs. wandering thoughts

2019

Neurofeedback requires a direct translation of neuronal brain activity to sensory input given to the user or subject. However, decoding certain states, e.g., mindfulness or wandering thoughts, from ongoing brain activity remains an unresolved problem. In this study, we used magnetoencephalography (MEG) to acquire brain activity during mindfulness meditation and thought-inducing tasks mimicking wandering thoughts. We used a novel real-time feature extraction to decode the mindfulness, i.e., to discriminate it from the thought-inducing tasks. The key methodological novelty of our approach is usage of MEG power spectra and functional connectivity of independent components as features underlyin…

Music Therapy for Depression Enhanced With Listening Homework and Slow Paced Breathing: A Randomised Controlled Trial

2021

Introduction: There is evidence from earlier trials for the efficacy of music therapy in the treatment of depression among working-age people. Starting therapy sessions with relaxation and revisiting therapeutic themes outside therapy have been deemed promising for outcome enhancement. However, previous music therapy trials have not investigated this issue.Objective: To investigate the efficacy of two enhancers, resonance frequency breathing (RFB) and listening homework (LH), when combined with an established music therapy model (trial registration number ISRCTN11618310).Methods: In a 2 × 2 factorial randomised controlled trial, working-age individuals with depression were allocated into gr…

Online Adaptation to Altered Auditory Feedback Is Predicted by Auditory Acuity and Not by Domain-General Executive Control Resources

2018

Published: 12 March 2018 When a speaker's auditory feedback is altered, he adapts for the perturbation by altering his own production, which demonstrates the role of auditory feedback in speech motor control. In the present study, we explored the role of auditory acuity and executive control in this process. Based on the DIVA model and the major cognitive control models, we expected that higher auditory acuity, and better executive control skills would predict larger adaptation to the alteration. Thirty-six Spanish native speakers performed an altered auditory feedback experiment, executive control (numerical Stroop, Simon and Flanker) tasks, and auditory acuity tasks (loudness, pitch, and …

Impact of a physician-targeted letter on opioid prescribing.

2020

We study the effect of a physician-targeted nudge letter on opioid prescribing. In May 2017, the Social Insurance Institution of Finland sent a personal information letter to all physicians who had issued a prescription containing at least 100 tablets of paracetamol-codeine combination to a new patient. The aim of the letter was to draw the physicians’ attention to their prescribing practices and to decrease the size of the first codeine prescription. Using individual level register data and a difference-in-differences strategy, we estimate that the letter decreased the average number of tablets purchased by new patients by 12.5 percent and the probability of a first purchase being at least…

Metrics Framework for Cycle-Time Reduction in Software Value Creation

2015

Agile software development methodologies driving cycle-time reduction have been shown to improve efficiency, enable shorter lead times and place a stronger focus on customer needs. They are also moving the process development focus from cost-reduction towards value creation. Optimizing software development based on lean and agile principles requires tools and metrics to optimize against. We need a new set of metrics that measure the process up to the point of customer use and feedback. With these we can drive cycle time reduction and improve value focus. Recently the lean startup methodology has been promoting a similar approach within the startup context. In this paper, we develop and vali…
