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…

ACTing for depressive symptoms : a longitudinal study of a brief 4-session acceptance- and value-based intervention for symptoms of depression

2018

The main objective of this study was to investigate a brief 4-session intervention based on a theoretical framework of acceptance and commitment therapy (ACT), and to explore its short- and long-term effectiveness among individuals reporting depressive symptoms. Additionally, the research aimed at further exploring the elements of psychological flexibility and mindfulness associated with improvements in depressive symptoms. The dissertation comprises three studies. Study I investigated the effectiveness of the brief intervention compared to a waiting-list control group. In total, 57 participants were randomized into either the ACT intervention (n = 28) or the waiting-list control (WLC; n = …

How long-term mindfulness meditation practice affects the brain mechanisms of attention?

2015

In the last few decades, the beneficial effects of meditation and mindfulness have been broadly researched. Because attention plays a key role in mindfulness, it has been assumed that long-term practice of mindfulness meditation also has an impact on attention on neurophysiological level.In the current study, we explored how the long-term practice of mindfulness meditation affects the brain mechanisms of attention. We compared two groups, long-term meditation practisers and meditation novices. EEGscanning was conducted during an attention task of dichotic listening, where two stories were listened simultaneously, and participants were asked to concentrate in only one of the stories at a tim…

Mindfulness-acceptance-commitment program for athletes and exercisers : an action research case study

2016

Control-based psychological skills training (PST) practices have been widely capitalized on in sport for the past few decades, despite inconsistent empirical evidence of their efficacy on sport performance. The Mindfulness-Acceptance-Commitment (MAC) program has preliminary support as an additional approach in performance enhancement, however, there is very limited research involving its implementation especially within group settings. Current study was aimed at planning, implementation, and evaluation of a seven-session MAC program among a diverse group of active athletes and regular exercisers (n=16). This study was an educational action research case study with a mixed method design. Per…

Examining mediators of change in wellbeing, stress, and depression in a blended, Internet-based, ACT intervention for university students

2020

A coach-guided Acceptance and Commitment Therapy (ACT) intervention that uses a blended approach of two face-to-face and five online sessions (iACT; N = 33) has been found to be more effective than a waiting-list control condition (WLC; N = 35) at enhancing the wellbeing of university students while also reducing stress and depression. The present study explored possible mediators of change that may account for the outcomes of the study. Mediation analyses revealed that changes in the non-reactivity subscale of mindfulness mediated changes in wellbeing, depression, and stress in the iACT group. In addition, changes in the sense of coherence subscale of meaningfulness mediated changes in all…

Mindfulness-, hyväksyntä- ja arvopohjaisen (MIHA) ohjelman vaikuttavuus työuupumusoireiden lievittäjänä : tutkimusyhteenveto Muupu-hankkeesta

2016

Työuupumuksen lievittämiseksi on alettu maailmalla käyttää mindfulness-, hyväksyntä- ja arvopohjaisia (MIHA) -menetelmiä. Muupu-tutkimuksen tarkoituksena oli selvittää, voidaanko uudenlaisella, kahdeksanviikkoisella MIHA- ohjelmalla lievittää työuupumusoireita tehokkaasti. Ohjelma toteutettiin ryhmä- ja verkkointervention yhdistelmänä. Muupu-tutkimuksessa selvitettiin sekä ohjelman vaikuttavuutta että sen vaikutusmekanismeja. 218 tutkittavaa satunnaistettiin kahteen ryhmään: MIHA-interventioryhmään ja tavanomaista tukea (TAV) saavien ryhmään. Tutkimuksessa hyödynnettiin myös pilottiryhmän (n = 24) ja heidän vastinpariensa (n = 24) kyselyvastauksia. Noin 80 % tutkittavista oli naisia, ja yli…

Preventing nocebo suggestions through mindfulness meditation

2017

The nocebo effect is a negative outcome resulting from the belief that a desired treatment has either not been received, or that a received treatment is harmful (Hurst, Foad & Beedie, 2015). This effect has been empirically demonstrated to have negative effects on sporting performance and physical endurance. Expectation has been the foremost mechanism in producing the nocebo response and manipulation through verbal suggestions is arguably the most powerful way to generate expectation (Carlino, Benedetti & Pollo, 2014). The purpose of the study was to investigate whether mindfulness practice can counteract the negative expectations given by potentially harmful nocebo effects, in this case ve…
