Self-Diffusion of Associating Star-Shaped Polymers

2016

The dynamics of associating bonds in transient polymer networks exerts a paramount influence on their relaxation and time-dependent mechanical properties. In particular, diffusive motion of polymers mediated by the dissociation and association equilibrium of reversible junctions can affect the materials’ structural stability, dynamic mechanical properties, and a broad spectrum of functionality that arises from the constant motion of polymer chains. In this work, forced Rayleigh scattering is used to measure the diffusion of terpyridine end-functionalized four-arm poly(ethylene glycol) polymers transiently interlinked by zinc ions in organic solvent across a wide range of length and time sca…

Deuteron relaxation times T1 of polystyrenes deuterated at the backbone (PS-d3) and the phenyl ring (PS-d5), respectively, have been measured in solutions of benzene and diethyl malonate as a function of concentration and temperature. We conclude that the motion of the phenyl ring is faster than that of the backbone, the difference being smallest at high temperatures around 180°C. The temperatures dependence is discussed in relation to the activation energies in polystyrene.

Age, gender, and puberty influence the development of facial emotion recognition

2015

Our ability to differentiate between simple facial expressions of emotion develops between infancy and early adulthood, yet few studies have explored the developmental trajectory of emotion recognition using a single methodology across a wide age-range. We investigated the development of emotion recognition abilities through childhood and adolescence, testing the hypothesis that children’s ability to recognise simple emotions is modulated by chronological age, pubertal stage and gender. In order to establish norms, we assessed 478 children aged 6-16 years, using the Ekman-Friesen Pictures of Facial Affect. We then modelled these cross-sectional data in terms of competence in accurate recogn…

MOTION SICKNESS IN CHILDHOOD MIGRAINE

2017

Background: Migraine is a chronic, progressive, and debilitating disorder that has an impact on the lives of millions of individuals. The origins of the disability can be traced into childhood and adolescence for most adult migraine sufferers. The group of periodic syndromes consists in symptoms related to migraine, thought to be migraine equivalent or precursors. Aim of this study is to assess the role of MS as risk factors for childhood migraine. Materials and methods: 441 subjects (211 Females) aged 6-13 years (mean 9.20; SD 2.42), consecutively referred between October 2007 to March 2009 for primary headaches to pediatric Centers for Headache in Childhood. Control group consisted of 365…

Physically Experienced Reactions and Music : A Questionnaire Study of Musicians and Non-Musicians

2013

Studying physically experienced reactions such as chills, tears, and racing heart (sometimes generally referred to as thrills) represents an important approach to music and emotion. A questionnaire study methodologically based on Sloboda's influential article (1991) partly confirms the results but disagrees with them in some findings. More frequent physical reactions during music listening in women reported by previous studies were confirmed only for respondents older that 30 in thisstudy. In partial accordance with some of previous studies, more frequent physical reactions in professional musicians than in amateur musicians and non-musicians were found and goose-pimples and chills appeared…

Nonverbal synchrony in couple therapy linked to clients’ well-being and the therapeutic alliance

2021

Nonverbal synchrony between individuals has a robust relation to the positive aspects of relationships. In psychotherapy, where talking is the cure, nonverbal synchrony has been related to a positive outcome of therapy and to a stronger therapeutic alliance between therapist and client in dyadic settings. Only a few studies have focused on nonverbal synchrony in multi-actor therapy conversations. Here, we studied the synchrony of head and body movements in couple therapy, with four participants present (spouses and two therapists). We analyzed more than 2000min of couple therapy videos from 11 couple therapy cases using Motion Energy Analysis and a Surrogate Synchrony (SUSY), a procedure us…

A phenomenological investigation of the emotional experiences of elite Brazilian coaches

2014

Coaches of elite athletes often need to work under stressful conditions and therefore may experience moments where emotional intensity is running very high. As a result, their physical and mental well-being may be affected. Nevertheless, little attention has been given to the emotional side of the coaches in current scientific literature (Potrac, Jones, Purdy, Nelson, & Marshall, 2013). With this in mind, the purpose of this study was to explore coaches’ stressors and other pleasant and unpleasant emotional experiences related to their coaching performance. Specifically, coaches’ awareness of their emotions and situational triggers were examined. Six highly experienced Brazilian coaches wer…

Emotional Information Space in Designing AI Technologies

2022

Current and future AI design needs to recognize the intertwined nature of cognition and affect to design more human-like intelligent systems. The majority of current AI design focuses on cognitive information processes and knowledge. However, human action and human-like actions must also consider the emotional aspects of the environment. We present the concept of emotional information space, which incorporates all issues within a certain environment with cognitively appraised affective meanings and the ability to encode these information contents into designing emotionally intelligent technologies.

Designing a Low-Fat Food Packaging: Comparing Consumers’ Responses in Virtual and Physical Shopping Environments

2021

This paper aims to test to what extent emotional responses towards a low-fat product presented virtually converge with emotional responses toward this product when presented physically. Second, we want to probe if low-order emotions (physiological/unconscious responses) and high-order emotions (cognitive/conscious responses) converge to explain healthy product choices. To this end, 83 young participants were engaged in our experiment. Two packaging design variables were manipulated with the help of a real company (the color and the message), so that six different packages were created. Two different buying contexts were simulated: A virtual context and a physical context. Physiological resp…
