Being able to classify experienced emotions by identifying distinct neural responses has tremendous value in both fundamental research (e.g. positive psychology, emotion regulation theory) and in applied settings (clinical, healthcare, commercial). We aimed to decode the neural representation of the experience of two discrete emotions: sadness and disgust, devoid of differences in valence and arousal. In a passive viewing paradigm, we showed emotion evoking images from the International Affective Picture System to participants while recording their EEG. We then selected a subset of those images that were distinct in evoking either sadness or disgust (20 for each), yet were indistinguishable on normative valence and arousal. Event-related potential analysis of 69 participants showed differential responses in the N1 and EPN components and a support-vector machine classifier was able to accurately classify (58%) whole-brain EEG patterns of sadness and disgust experiences. These results support and expand on earlier findings that discrete emotions do have differential neural responses that are not caused by differences in valence or arousal.

Background: Sexual deviance is regarded as an important risk factor for sexual offending. However, little is known about the development of deviant sexual interests. The transfer of arousal between emotions, i.e., excitation transfer, could attribute sexual salience to stimuli that would otherwise not be sexual in nature. As such, excitation transfer could contribute to the very beginning of unusual or deviant sexual interests. The current protocol proposes a study to investigate to what extent excitation transfer occurs, i.e., to what extent genital and subjective sexual arousal to sexual stimuli is higher in an emotional state than in a neutral state. Following a prior pilot study, several adjustments were made to the study protocol, including a stronger emotional manipulation by using 360-degree film clips and the inclusion of a larger and more sexually diverse sample. Methods: We will recruit 50 adult male volunteers with diverse sexual interests. We will induce sexual arousal in four different emotional states (aggression/dominance, endearment, fear, disgust) and a neutral state. Sexual arousal will be measured genitally using penile plethysmography and subjectively via self-report. Using paired samples t-tests, sexual arousal in the emotional states will be compared with sexual arousal in the neutral state. Discussion: We aim to show that arousal in response to emotional stimuli that are initially nonsexual in nature, can enhance sexual arousal. These findings have potentially important implications for the development of unusual and/or deviant sexual interests and possibly for the treatment of such sexual deviant interests in people who have committed sexual offenses.

Dit proefschrift onderzoekt de manieren waarop affectieve reacties op lichamen met een handicap worden gerepresenteerd en hoe dit ons uitnodigt om deze lichamen esthetisch te lezen. Ik stel dat deze affectieve impact begrepen kan worden als een ‘affordance’, een term die ik gebruik om te beschrijven hoe de verschijning van en interactie met gehandicapte lichamen affectieve reacties teweegbrengt, zoals angst, verwondering of walging. Ik bestudeer de relatie tussen representatie en affectieve reacties via literatuur en andere kunstvormen. Door middel van close readings van literaire teksten en kunstwerken biedt dit proefschrift een alternatief voor het zogenaamde modeldenken - een benadering die categorisering benadrukt. In plaats daarvan stel ik een lezing voor die zich richt op hoe lichamelijke capaciteiten cultureel en sociaal vertaald worden in (on)vermogens. In tegenstelling tot taxonomische benaderingen die categoriseren en generaliseren, maakt deze methode het mogelijk om van het bijzondere naar het private te gaan. Kunstwerken, hoewel vatbaar voor generalisatie, benadrukken hun uniciteit en weerstaan categorisering. Door te analyseren hoe verschillende kunstvormen gehandicapte lichamen representeren, geeft dit proefschrift een nieuwe dimensie aan het begrijpen van onze emotionele reacties en de esthetische waardering van lichamelijke diversiteit.

Due to the environmental and nutritional benefits of insects, their consumption would be one of the solutions to feed the growing human population. Despite the increasing interest in the use of insects as food and feed, consumer acceptance is the major obstacle to successful implementation in Western countries and we studied the factors that influence consumer acceptance in a group of university students from Germany and the Netherlands. In this exploratory research, a survey was conducted (n = 222). Socio‐demographic and psychological factors were established from a theoretical review. In addition, we elaborated on questions regarding information on the health and environmental benefits of consuming insects. Initially, the data obtained are presented through descriptive statistics. The influence of the socio‐demographic and psychological factors, and the information on the willingness to accept insects as animal feed and human food was analyzed using correlations and multiple linear regressions. Results showed more willingness to accept insects as animal feed than in human food. The acceptance among German and Dutch students seems to be driven by issues similar to those in other European countries, such as visual aspects and knowledge about the benefits. The effect of the information on willingness constitutes an important finding of this study, especially for the use of insects in animal feed, since most of the previous studies have focused on the use of insects as human food. Our data support the need to inform and educate consumers about the environmental and health benefits of entomophagy. We conclude that effective efforts to implement entomophagy could increase the level of familiarity with the insect food and inform (or educate) consumers about its benefits. Insights from this study are useful to address studies focusing on specific segments of possible early adopters and consequently addressing communication strategies in this market segmentation.

This study assessed the effect of visitors' personality and emotional response on finding positive meaning in life and the intention to spread positive word of mouth. The sample (n = 260) consists of visitors to Sachsenhausen Memorial and Museum near Berlin. Findings indicate that the emotion of interest positively contributes to finding positive meaning in life and positive word of mouth. The effects of personality are marginal. Personality explains little of the variance in positive meaning and positive word of mouth. Emotional response accounts for 25% of the variance in finding positive meaning in life-in terms of finding personal benefit from the visit, controlled for personality. Despite the dominant negative emotional response, tourists find positive meaning in their visit. These findings correspond with those observed in studies on personal trauma and loss. Positive meaning could potentially contribute to adjustment processes to cope with what occurred. Future research should include address longer term effects on postvisit behavior.

There is a growing number of eHealth interventionsaiming at enhancing lifestyle to address obesity. However, theexisting interventions do not take the emotional aspects ofobesity into account. Forty percent of the overweightpopulation is an emotional eater. Emotional eaters gain weightbecause of poor emotion regulation, not just due to bad eatinghabits. We aim at developing a personalized virtual coach‘Denk je zèlf!’ providing support for self-regulation ofemotions for young obese emotional eaters. This paperpresents an eCoaching model and a research study protocolaiming at the validation of persuasive coaching strategies basedon behavior change techniques. Ultimately, we aim atdesigning a personalized eCoaching framework, allowing us tooptimally translate successful behavior change mechanismsand techniques, such as dialectical strategies, into personalizedpersuasive coaching strategies.

The purpose of this study was to examine changes in specific positive and negative emotions during a vacation, as well as their interactions with personality. Using a questionnaire and diary, 39 American and Dutch vacationers' emotions high in both positivity and arousal exhibited an inverted U-shape curve, suggesting that they felt better during the second section rather than the end of their vacation. None of the negative emotions exhibited significant changes over time. When the impacts of personality on specific emotions were addressed, personality was found to determine the baseline levels of fear and sadness and moderate change in disgust across individuals' vacations. The results suggest that tourism managers and researchers must acknowledge and address the change of emotions tourists experience during a vacation and the role of personality in influencing that change.

This study explored Dutch people's expected intensity of emotional responses of a potential visit to a concentration camp memorial site in the Netherlands. A total of 1050 online panel members participated in a questionnaire that contained a 33-item emotion scale. Results reveal that individuals with a closeness to the Holocaust expect to feel most emotions more intensely, specifically emotions that are traditionally considered ‘positive’, such as pride, love, joy, inspiration, excitement and affection. Overall, respondents expect to feel disgust, shock, compassion and sadness the strongest. Those who look from the viewpoint of the offenders mainly expect to feel emotions that are traditionally considered ‘negative’, whereas those who took the point of view of the victims also expect a more ‘positive’ emotional reaction to the visit. Managerial implications address aspects of education, storytelling and authenticity.
