This study explores the effects of various spatiotemporal dynamic texture characteristics on human emotions. The emotional experience of auditory (eg, music) and haptic repetitive patterns has been studied extensively. In contrast, the emotional experience of visual dynamic textures is still largely unknown, despite their natural ubiquity and...

We explore possibilities for enhancing the generality, portability and robustness of emotion recognition systems by combining data-bases and by fusion of classifiers. In a first experiment, we investigate the performance of an emotion detection system tested on a certain database given that it is trained on speech from either the same database,...

In a longitudinal cross-lagged study, the determinants and consequences were examined of presenteeism (going to work despite feeling unhealthy). All variables were measured with questionnaires in 2002 and in 2004 among a representative Dutch sample (N = 653), and these data were individually and longitudinally matched. In 2002 as well as in 2004...

This study examined which individuals in particular are susceptible or resistant to develop overweight in our current obesogenic environment. A cross-sectional study was conducted in a sample of 1342 people representative of the general population in the Netherlands. Overweight-level (normal body weight ≥ 17.5 BMI [weight in kilograms/height in...

In this paper, we describe emotion recognition experiments carried out for spontaneous affective speech with the aim to compare the added value of annotation of felt emotion versus annotation of perceived emotion. Using speech material available in the TNO-GAMING corpus (a corpus containing audiovisual recordings of people playing videogames),...

Affective user interfaces are usually characterized as interfaces that try to recognize, interpret and respond to human emotions. In this paper, we take a different perspective and investigate if and how a digital, interactive adaptive mirror, which is a game-like affective interface, can induce positive emotions in participants and how the...

This paper investigates if and how a digital, interactive affective mirror induces positive emotions in participants. We study whether the induced affect is repeatable after a fixed interval (Study 1) and how the social presence affects the emotion induction (Study 2). Results show that participants systematically feel more positive after an...

Background: The assessment of mental health problems in children with intellectual disability (ID) mostly occurs by filling out long questionnaires that are not always validated for children without ID. The aim of this study is to assess the differences in mental health problems between children with ID and without ID, using a short...

We investigated inter-observer agreement and the reliability of self-reported emotion ratings (i.e., self-raters judging their own emotions) in spontaneous multimodal emotion data. During a multiplayer video game, vocal and facial expressions were recorded (including the game content itself) and were annotated by the players themselves on...

Background: Little research has been conducted to date on women's postnatal emotional well-being and satisfaction with the care received in the Netherlands. The aim of this study was to investigate Dutch women's views of their birth experience 3 years after the event. Methods: A questionnaire was mailed to all women who had given birth in 2001...

We developed acoustic and lexical classifiers, based on a boosting algorithm, to assess the separability on arousal and valence dimensions in spontaneous emotional speech. The spontaneous emotional speech data was acquired by inviting subjects to play a first-person shooter video game. Our acoustic classifiers performed significantly better than...

Objectives: The aim of this study is to examine the role of coping styles in sickness absence. In line with findings that contrast the reactive-passive focused strategies, problem-solving strategies are generally associated with positive results in terms of well-being and overall health outcomes; our hypothesis is that such strategies are...

Background. The aim of this study was to assess the prevalence in the general population of parents' concerns about the development of their child, to identify groups at risk and to assess the association between parents' concerns and professional judgement. Methods. We obtained cross-sectional data on a Dutch nationally representative sample of...

In this paper, an emotion classification system based on speech signals is presented. The classifier can identify the most common emotions, namely anger, neutral, happiness and fear. The algorithm computes a number of acoustic features which are fed into the classifier based on a pattern recognition approach. The classification system is of...

Promotie Inge Wetzer over het sociaal delen van emoties. Een luisterend oor helpt niet altijd. Mensen zijn geen binnenvetters, 85% van de negatieve ervaringen van mensen worden met andere mensen gedeeld. Inge Wetzer onderzocht het delen van emoties, de motivatie daarvoor, de gewenste reactie en het effect daarvan. Wetzer verdiepte zich in...

In this paper, we present a detection approach and an ‘open-set’ detection evaluation methodology for automatic emotion recognition in speech. The traditional classification approach does not seem to be suitable and flexible enough for typical emotion recognition tasks. For example, classification does not have an appropriate way to cope with ...

In this paper, we present a multimodal affective mirror that senses and elicits laughter. Currently, the mirror contains a vocal and a facial affect-sensing module, a component that fuses the output of these two modules to achieve a user-state assessment, a user state transition model, and a component to present audiovisual affective feedback...

This paper introduces a detection methodology for recognition technologies in speech for which it is dif cult to obtain an abundance of non-target classes. An example is language recognition, where we would like to be able to measure the detection capability of a single target language without confounding with the modeling capability of non...
