Decreased intersubject synchrony in dynamic valence ratings of sad movie contents in dysphoric individuals

2021

Emotional reactions to movies are typically similar between people. However, depressive symptoms decrease synchrony in brain responses. Less is known about the effect of depressive symptoms on intersubject synchrony in conscious stimulus-related processing. In this study, we presented amusing, sad and fearful movie clips to dysphoric individuals (those with elevated depressive symptoms) and control participants to dynamically rate the clips’ valences (positive vs. negative). We analysed both the valence ratings’ mean values and intersubject correlation (ISC). We used electrodermal activity (EDA) to complement the measurement in a separate session. There were no group differences in either t…

Negative and Positive Bias for Emotional Faces: Evidence from the Attention and Working Memory Paradigms

2021

Visual attention and visual working memory (VWM) are two major cognitive functions in humans, and they have much in common. A growing body of research has investigated the effect of emotional information on visual attention and VWM. Interestingly, contradictory findings have supported both a negative bias and a positive bias toward emotional faces (e.g., angry faces or happy faces) in the attention and VWM fields. We found that the classical paradigms—that is, the visual search paradigm in attention and the change detection paradigm in VWM—are considerably similar. The settings of these paradigms could therefore be responsible for the contradictory results. In this paper, we compare previou…

IEEE Access Special Section Editorial : Cloud and Big Data-Based Next-Generation Cognitive Radio Networks

2019

In cognitive radio networks (CRN), secondary users (SUs) are required to detect the presence of the licensed users, known as primary users (PUs), and to find spectrum holes for opportunistic spectrum access without causing harmful interference to PUs. However, due to complicated data processing, non-real-time information exchange and limited memory, SUs often suffer from imperfect sensing and unreliable spectrum access. Cloud computing can solve this problem by allowing the data to be stored and processed in a shared environment. Furthermore, the information from a massive number of SUs allows for more comprehensive information exchanges to assist the resource allocation and interference ma…

Ahdistaako koululiikunta? : yhdeksäsluokkalaisten ahdistuneisuuskokemukset koulun liikuntatunneilla

2014

TIIVISTELMÄ Lari Sädekoski (2014). Ahdistaako koululiikunta? Yhdeksäsluokkalaisten ahdistuneisuusko-kemukset koulun liikuntatunneilla. Liikuntakasvatuksen laitos. Jyväskylän Yliopisto. Liikunta-pedagogiikan pro gradu – tutkielma. 79 s, 2 liitettä. Tutkimuksen tavoitteena oli selvittää peruskoulun yhdeksäsluokkalaisten tyttöjen ja poikien kokemaa tilanneahdistuneisuutta koulun liikuntatunneilla. Aihe on tärkeä, koska vielä murros-iässä elävät yläkouluikäiset nuoret ovat alttiita kielteisille kokemuksille, ja yleisesti kouluviih-tyvyys on Suomessa varsin heikkoa. Tilanneahdistuneisuutta mittaavat osa-alueet olivat so-maattinen ja kognitiivinen ahdistuneisuus sekä huolestuneisuus. Tarkoituksen…

Attentional processes in typically developing children as revealed using brain event-related potentials and their source localization in Attention Ne…

2019

AbstractAttention-related processes include three functional sub-components: alerting, orienting, and inhibition. We investigated these components using EEG-based, brain event-related potentials and their neuronal source activations during the Attention Network Test in typically developing school-aged children. Participants were asked to detect the swimming direction of the centre fish in a group of five fish. The target stimulus was either preceded by a cue (centre, double, or spatial) or no cue. An EEG using 128 electrodes was recorded for 83 children aged 12–13 years. RTs showed significant effects across all three sub-components of attention. Alerting and orienting (responses to double …

The effectiveness and applicability of different lifestyle interventions for enhancing wellbeing : the study design for a randomized controlled trial…

2014

Background: Obesity and stress are among the most common lifestyle-related health problems. Most of the current disease prevention and management models are not satisfactorily cost-effective and hardly reach those who need them the most. Therefore, novel evidence-based controlled interventions are necessary to evaluate models for prevention and treatment based on self-management. This randomized controlled trial examines the effectiveness, applicability, and acceptability of different lifestyle interventions with individuals having symptoms of metabolic syndrome and psychological distress. The offered interventions are based on cognitive behavioral approaches, and are designed for enhancing…

The chronnectome of musical beat

2020

Keeping time is fundamental for our everyday existence. Various isochronous activities, such as locomotion, require us to use internal timekeeping. This phenomenon comes into play also in other human pursuits such as dance and music. When listening to music, we spontaneously perceive and predict its beat. The process of beat perception comprises both beat inference and beat maintenance, their relative importance depending on the salience of beat in the music. To study functional connectivity associated with these processes in a naturalistic situation, we used functional magnetic resonance imaging to measure brain responses of participants while they were listening to a piece of music contai…

Event-related potentials to task-irrelevant sad faces as a state marker of depression

2018

Negative bias in face processing has been demonstrated in depression, but there are no longitudinal investigations of negative bias in symptom reduction. We recorded event-related potentials (P1 and N170) to task-irrelevant facial expressions in depressed participants who were later provided with a psychological intervention and in never depressed control participants. Follow-up measurements were conducted for the depressed group two and 39 months later. Negative bias was found specifically in the depression group, and was demonstrated as enlarged P1 amplitude to sad faces, which normalized in the follow-up measurements when the participants had fewer symptoms. Because the P1 amplitude reco…

Reducing health inequalities trough digital options in mental health: A physician's perspective.

2019

This paper explores the physicians’ perspective regarding the potential of computerised Cognitive Behavioural Therapies (cCBTs) to overcome inequalities in the context of mental health care provision. The main benefits were related to the ability of cCBTs to provide care in a convenient and efficient manner, enhancing its accessibility. These aspects were perceived more important than cost-effectivity of treatment, which is often claimed to be the key benefit of cCBTs. Age and general acceptance of CBT were the most significant individual-level separators of perceptions, while the sector in which the physician works was seen as the main structural-level separator. peerReviewed
