Sympathetic nervous system synchrony between participants of couple therapy

2017

Synchrony, or the moment-by-moment coordination between people in social situations, has been connected with increased liking and rapport. However, this type of synchrony is an underexplored area with regard to autonomic nervous system activity. The purpose of this research was to study physiological synchrony between participants in couple therapy by focusing on the sympathetic nervous system (SNS), which reflects arousal and emotional reactions. The data comprised 12 couple therapy cases (24 clients, 10 therapists) participating in the Relational Mind in Events of Change in Multiactor Therapeutic Dialogues (2013-2016) research project. Electrodermal activity (EDA) and heart rate were reco…

Associations Between Sympathetic Nervous System Synchrony, Movement Synchrony, and Speech in Couple Therapy

2022

Background: Research on interpersonal synchrony has mostly focused on a single modality, and hence little is known about the connections between different types of social attunement. In this study, the relationship between sympathetic nervous system synchrony, movement synchrony, and the amount of speech were studied in couple therapy. Methods: Data comprised 12 couple therapy cases (24 clients and 10 therapists working in pairs as co-therapists). Synchrony in electrodermal activity, head and body movement, and the amount of speech and simultaneous speech during the sessions were analyzed in 12 sessions at the start of couple therapy (all 72 dyads) and eight sessions at the end of therapy (…

Teachers’ situational physiological stress and affect

2023

Since teaching is a demanding and stressful profession, the study of teachers’ physiological stress in the classroom setting is an emerging field. In cross-sectional studies self-reported stress and affect are related, but less is known about the intraindividual relations between situational physiological stress and corresponding positive and negative affect. The aim of our study was to investigate the associations between situational physiological stress (six salivary cortisol samples per day) and self-reported situational affect (Positive and Negative Affect Schedule four times a day) among 61 Finnish primary school teachers over two workdays. We present a novel multilevel structural equa…

Ihmisen visuaalinen hahmottamiskyky ja fysiologisen datan esittäminen

2015

Tutkimuksen tarkoituksena oli saada ymmärrys siitä, miten ihminen ymmär-tää visuaalista dataa ja miten fysiologista dataa kannattaa visualisoida. Tutki-muksen teoriaosuudessa syvennyttiin ihmisen visuaaliseen havaitsemis- ja hahmottamiskykyyn, tiedon visualisointiin ja visuaaliseen käytettävyyteen. Edellä mainittujen pohjalta luotiin suunnitteluperiaatteet fysiologisen (graafi-sen) datan esittämiselle. Tutkimuksen toimintaosuudessa tarkastelun kohtee-na oli Firstbeat Technologies Oy:n Hyvinvointianalyysin palautesivu, josta opinnäytteentekijä rakensi vaihtoehtoisen version perustuen suunnitteluperi-aatteisiin. Tutkimuksen taustalla oli ajatus Hyvinvointianalyysin tulossivujen selkiyttämises…

Hydrogen isotopes (δ2H) of polyunsaturated fatty acids track bioconversion by zooplankton

2022

1. Organisms at the base of aquatic food webs synthesize essential nutrients, such as omega-3 polyunsaturated fatty acids (n-3 PUFA), which are transferred to consumers at higher trophic levels. Many consumers, requiring n-3 long-chain (LC) PUFA, such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), have limited ability to biosynthesize them from the essential dietary precursor α-linolenic acid (ALA) and thus rely on dietary provision of LC-PUFA. 2. We investigated LC-PUFA metabolism in freshwater zooplankton using stable hydrogen isotopes (δ2H) of fatty acids as tracers. We conducted feeding experiments with the freshwater keystone grazer Daphnia to quantify changes in the δ2…

Exercise and inflammation with special reference to resistance training

2018

The aim of the present dissertation was to examine the acute and chronic effects of resistance exercise on inflammation markers in young men. In addition, the effect of combined resistance and endurance training on inflammation was assessed. The present dissertation consisted of four studies. Acute inflammation response was evaluated using cross-sectional design after hypertrophic and maximal (n=12) resistance exercise bouts (I). In addition, acute inflammation was examined before and after resistance training (RT) consisting either hypertrophic or maximal explosive (n=8) resistance exercise bouts (RE) (II). The effect of RT on basal levels of markers of systemic inflammation was evaluated …

Trait emotional intelligence and its associations with subjective and physiological well-being

2018

The present thesis examined the association between trait emotional intelligence (EI) and well-being (subjective well-being [SWB] and physiological well-being) among Japanese participants (eldercare nurses and undergraduate university students). This research had four primary goals: First, to identify profiles of trait EI and to investigate their association with SWB (Study I); second, to examine the role of trait EI in the process of SWB (Study II); third, to investigate the association of trait EI with psychological state and physiological well-being in a laboratory-based stress induction condition (Study III); and fourth, to investigate the association of trait EI with affect and physiol…

Associations Between Adolescents' Subjectively Experienced Emotions and Psychophysiological Reactions in Achievement Situations

2022

This study investigated associations of early adolescents' (N=190, median age = 12) subjectively experienced emotions and psychophysiological reactions in achievement situations. Self-reported questions assessed adolescents' experienced emotions. Additionally, adolescents' autonomic nervous system (ANS) reactions were recorded; skin-conductance response (SCR) and heart rate (HR) were used to measure sympathetic nervous system activity, and heart rate variability (HRV) was used to measure parasympathetic nervous system activity. The between-person-level results of multilevel modeling showed that increased HR was associated with higher levels of hope and fear and that decreased SCR was associ…

Autophagy is induced by resistance exercise in young men but unfolded protein response is induced regardless of age

2018

Aim Autophagy and unfolded protein response (UPR) appear to be important for skeletal muscle homoeostasis and may be altered by exercise. Our aim was to investigate the effects of resistance exercise and training on indicators of UPR and autophagy in healthy untrained young men (n = 12, 27 ± 4 years) and older men (n = 8, 61 ± 6 years) as well as in resistance‐trained individuals (n = 15, 25 ± 5 years). Methods Indicators of autophagy and UPR were investigated from the muscle biopsies after a single resistance exercise bout and after 21 weeks of resistance training. Results Lipidated LC3II as an indicator of autophagosome content increased at 48 hours post‐resistance exercise (P < .05) and …
