Significant Moments in a Couple Therapy Session: Towards the Integration of Different Modalities of Analysis
This chapter presents a couple therapy session from four different research perspectives: The verbal dialogue was analysed with the Dialogical Investigations of Happenings of Change method, the embodied reactions of each participant were analysed by examining the electrodermal activity of each participant, and nonverbal synchrony was observed between the participants. Stimulated Recall Interviews, conducted individually after the session, were used to gain insights on the participants’ thoughts and feelings concerning particular moments in the session. We wished to determine what could be learned from the embodied reactions of the participants in couple therapy, including whether the data o…
A moment within the psychoanalytic psychotherapy of an adult female patient – The meanings of nonverbal and bodily expressions
This case study adresses the multiple meanings of a moment of strong non-verbal and bodily expression within a course of psychoanalytic psychotherapy. One therapy session was video-recorded in the ...
On application of kernel PCA for generating stimulus features for fMRI during continuous music listening
Abstract Background There has been growing interest towards naturalistic neuroimaging experiments, which deepen our understanding of how human brain processes and integrates incoming streams of multifaceted sensory information, as commonly occurs in real world. Music is a good example of such complex continuous phenomenon. In a few recent fMRI studies examining neural correlates of music in continuous listening settings, multiple perceptual attributes of music stimulus were represented by a set of high-level features, produced as the linear combination of the acoustic descriptors computationally extracted from the stimulus audio. New method fMRI data from naturalistic music listening experi…
Data-driven analysis for fMRI during naturalistic music listening
Interest towards higher ecological validity in functional magnetic resonance imaging (fMRI) experiments has been steadily growing since the turn of millennium. The trend is reflected in increasing amount of naturalistic experiments, where participants are exposed to the real-world complex stimulus and/or cognitive tasks such as watching movie, playing video games, or listening to music. Multifaceted stimuli forming parallel streams of input information, combined with reduced control over experimental variables introduces number of methodological challenges associated with isolating brain responses to individual events. This exploratory work demonstrated some of those methodological challeng…

Automatic subgenre classification of heavy metal music
Automatic genre classification of music has been of interest for researchers over a decade. Many success-ful methods and machine learning algorithms have been developed achieving reasonably good results. This thesis explores automatic sub-genre classification problem of one of the most popular meta-genres, heavy metal. To the best of my knowledge this is the first attempt to study the issue. Besides attempting automatic classification, the thesis investigates sub-genre taxonomy of heavy metal music, highlighting the historical origins and the most prominent musical features of its sub-genres. For classification, an algorithm proposed in (Barbedo & Lopes, 2007) was modified and implemented i…
The added value of studying embodied responses in couple therapy research : A case study
This article reports on the added value of embodied responses identified through sympathetic nervous system (SNS) activity in couple therapy research. It focuses on moments of change and the timing of therapeutic interventions or therapeutic moves in a couple therapy session. The data for this single‐case study comprise couple therapy process videotapes recorded in a multi‐camera setting, and measurements of participants’ SNS activity. The voluntary participants were a marital couple in their late thirties and two middle‐aged male psychotherapists. The division into topic segments showed how the key issue of seeking help, which was found to comprise three separate components, was repeatedly…
Combining PCA and multiset CCA for dimension reduction when group ICA is applied to decompose naturalistic fMRI data
An extension of group independent component analysis (GICA) is introduced, where multi-set canonical correlation analysis (MCCA) is combined with principal component analysis (PCA) for three-stage dimension reduction. The method is applied on naturalistic functional MRI (fMRI) images acquired during task-free continuous music listening experiment, and the results are compared with the outcome of the conventional GICA. The extended GICA resulted slightly faster ICA convergence and, more interestingly, extracted more stimulus-related components than its conventional counterpart. Therefore, we think the extension is beneficial enhancement for GICA, especially when applied to challenging fMRI d…
Affective Arousal During Blaming in Couple Therapy: Combining Analyses of Verbal Discourse and Physiological Responses in Two Case Studies
Blaming one’s partner is common in couple therapy and such moral comment often evokes affective arousal. How people attune to each other as whole embodied beings is a current focus of interest in psychotherapy research. This study contributes to the literature by looking at attunement during critical moments in therapy interaction. Responses to blaming in verbal dialogue and at the level of the autonomic nervous system (ANS) were investigated in two couple therapy cases with a client couple and two therapists. Video-recorded couple therapy sessions were analyzed using discursive psychology and a narrative approach. The use of positioning, a discourse analytic tool, was also studied. ANS res…

Electrodermal activity in couple therapy for intimate partner violence
The aim of this study was to examine the extent to which intimate partner violence (IPV) is discussed in couple therapy, what the participants say about it and how, and how the participants’ electrodermal activity (EDA) is activated during these discussions. We studied four couples for whom IPV was an issue in dialog with their therapists. We used thematic analysis and examined the differences in EDA (measured as skin conductance responses, SCRs) between the participants. We found that although IPV was discussed relatively little in therapy, when the topic arose the victims took an active part in the discussion. We also found that the main themes were descriptions of IPV, explanations for I…
Coupling of Action-Perception Brain Networks during Musical Pulse Processing: Evidence from Region-of-Interest-Based Independent Component Analysis
Our sense of rhythm relies on orchestrated activity of several cerebral and cerebellar structures. Although functional connectivity studies have advanced our understanding of rhythm perception, this phenomenon has not been sufficiently studied as a function of musical training and beyond the General Linear Model (GLM) approach. Here, we studied pulse clarity processing during naturalistic music listening using a data-driven approach (independent component analysis; ICA). Participants’ (18 musicians and 18 controls) functional magnetic resonance imaging (fMRI) responses were acquired while listening to music. A targeted region of interest (ROI) related to pulse clarity processing was defined…
