Challenges and added value of measuring embodied variables in psychotherapy
2022
Research on embodied aspects of clinical encounters is growing, but discussion on the premises of including embodied variables in empirical research is scarce. Studies have repeatedly demonstrated that embodied aspects of psychotherapy interaction are vital in developing a therapeutic alliance, and these should be considered to better understand the change process in psychotherapy. However, the field is still debating which methods should be used and which features of the embodied aspects are relevant in the clinical context. The field lacks methodological consistency as well as a theoretical model. In the Relational Mind research project, we have studied the embodied aspects of interaction…
The relationship between skin conductance and eye contact of spouses in couple therapy
2017
Katsekontaktin ja ihon sähkönjohtavuuden välistä yhteyttä on tutkittu aiemminkin, mutta tutkimusta ei ole tehty monitoimijaisessa terapiatilanteessa. Tämän tutkimuksen tarkoituksena oli tarkastella ihon sähkönjohtavuuden ja katsekontaktin välistä yhteyttä pariterapiassa pariskunnan välisen synkronian kautta, ja lisäksi selvittää, kuinka ihon sähkönjohtavuus muuttuu katsekontaktin eri hetkinä: ennen kuin katsekontakti alkaa, sen alkamishetkellä, ja alkamishetken jälkeen. Oletuksena oli, että ihon sähkönjohtavuuden vasteet nousevat katsekontaktin alkuhetkellä. Lisäksi tarkasteltiin, onko miehillä ja naisilla eroa ihon sähkönjohtavuuden vasteissa. Tutkimuksen otos koostui 11 pariskunnasta, joi…
Microscale X-ray mapping of CZT arrays: Spatial dependence of amplitude, shape and multiplicity of detector pulses
2018
In this work, we present the results of a microscale X-ray mapping of a 2 mm thick CZT pixel detector, with pixel pitches of 500 μm and 250 μm, using collimated synchrotron X-ray sources at the Diamond Light source (U. K.). The detector is dc coupled to a fast and low noise ASIC (PIXIE ASIC), characterized only by the preamplifier stage. A custom 16-channel digital readout electronics was used, able to perform online fast pulse shape and height analysis (PSHA), with low dead time and reasonable energy resolution at both low and high fluxes. The detector allows high bias voltage operation (> 5000 V/cm) and good energy resolution at room temperature (5.3 %, 2.3 % and 2.1 % FWHM at 22.1, 59…
Spectral entropy based neuronal network synchronization analysis based on microelectrode array measurements
2016
Synchrony and asynchrony are essential aspects of the functioning of interconnected neuronal cells and networks. New information on neuronal synchronization can be expected to aid in understanding these systems. Synchronization provides insight in the functional connectivity and the spatial distribution of the information processing in the networks. Synchronization is generally studied with time domain analysis of neuronal events, or using direct frequency spectrum analysis, e.g., in specific frequency bands. However, these methods have their pitfalls. Thus, we have previously proposed a method to analyze temporal changes in the complexity of the frequency of signals originating from differ…
Between looking back and moving ahead : an exploration of the role of the body and its movement in a music therapy case study
2017
We exist in this world through our bodies. Every single experience is stored in it, it helps us to communicate with others, relate and build meaningful relationships. However, when the connection to our experiences or the control over our body is disrupted by a traumatic experience or disease, we become disconnected from our genuine self and the world around us. Music therapy provides us with a space for integration – of painful or joyful memories, emotions, and our bodies. Especially in Western cultures this physical relationship to music is often neglected, even though music and dance probably developed simultaneously and are still very much the same in some African cultures. When we are …
Improved High-Fidelity IPMSM mathematical model Including Saturation, Cross-Coupling, Torque Ripple and Iron Loss effects
2022
For enhanced control algorithm design purposes, accurate and high-fidelity electrical machine mathematical models are fundamentals. Usually, accurate evaluation of electrical machine behaviour requires finite element analysis (FEA) with consequent high-computational times. This paper presents an improved high-fidelity Interior Permanent Magnet Synchronous Machine (IPMSM) mathematical model including saturation, cross-coupling, torque ripple and iron loss effects. This model has been implemented in Matlab®/Simulink environment and its parameters are implemented by the use of lookup tables. To validate the modelling approach proposed, a comparative analysis between the proposed Matlab®/Simuli…
Impact Evaluation of Innovative Selective Harmonic Mitigation Algorithm for Cascaded H-Bridge Inverter on IPMSM Drive Application
2021
This paper presents a detailed analysis of the use of a novel Harmonic Mitigation algorithm for Cascaded H-Bridge Multilevel Inverter in electrical drives for the transportation field. For this purpose, an enhanced mathematical model of Interior Permanent Magnet Synchronous Motor (IPMSM), that takes into account simultaneously saturation, cross-coupling, spatial harmonics, and iron loss effects, has been used. In detail, this model allows estimating accurately the efficiency and the torque ripple of the IPMSM, crucial parameters for transportation applications. Moreover, two traditional pulse width modulation strategies, Sinusoidal Phase-Shifted and Switching Frequency Optimal Phase-Shifted…
Two studies investigating the value of DJing for contemporary music education
2014
This research investigated the importance of cognitive skills learned through DJing and perspectives on the potential value of DJing for music education through two studies. The first was a qualitative investigation into contemporary perspectives on the potential value of DJing for music education. Participants were asked three questions in order to establish their perceptions concerning the cultural relevance of DJing regarding the skills that might be learned through DJing and how DJing might be incorporated into formal music education curriculums. Perspectives emerged that showed a majority of participants believed that DJs learn valuable musical skills, DJing had equal relevance with ot…
The Relationship between Auditory Imagery and Musical Synchronization Abilities in Musicians
2009
Musical ensemble performance requires precise action coordination. To maintain synchrony in the presence of expressive tempo variations, musicians presumably anticipate the sounds that will be produced by their co-performers and coordinate their own anticipated actions with these predictions. Anticipatory auditory images in pitch and time may facilitate such predictions. Two experiments were conducted to examine the contribution of different aspects of auditory imagery abilities to sensorimotor synchronization (SMS) in musicians. In Experiment 1, the acuity of single-tone pitch images was measured by an adjustment method and by adaptive threshold estimation. Different types of finger tappin…
An integrative dual-route model of rhythm perception and production
2009
An integrative dual-route model of rhythm perception and production is proposed here. Furthermore, an empirical study illustrated in the second part of this paper provides evidence of the existence of two different cognitive pathways. The development of the model is based on fundamental psychological principles of perception, action control and relevant neurobiological findings in rhythm processing and sensorimotor synchronization. Experiments with a dual-task paradigm were used during synchronization tapping to verify the fundamental assumptions of the model. The aim was to examine whether professional drummers show a change in tapping performance when their attention is drawn to another t…
