The present study investigated the potential of implicit physiological measures to provide objective measures of affective food experience in contrast to explicit self-report ratings in a cross-cultural context. Dutch and Thai participants viewed 120 food images portraying universal food image categories (regular and molded food) and cultural...

Early detection of exposure to a toxic chemical, e.g., in a military context, can be life-saving. We propose to use machine learning techniques and multiple continuously measured physiological signals to detect exposure, and to identify the chemical agent. Such detection and identification could be used to alert individuals to take appropriate...

Introduction Our visual, auditory, and tactile perception is not solely determined by what we process at a given moment in time, but also determined by what we perceived recently. These sequential effects can either be negative (repulsive) or positive (assimilative). Here, we investigated whether such sequential effects also occur in odor...

In teleoperations, robots are generally used because related tasks are too dangerous, uncomfortable or impossible for humans to perform. When using augmented reality to control robotic limbs in such teleoperations, it is essential to understand how these extra virtual limbs are experienced. In particular, the relationship between the embodiment...

How we perceive the world is not solely determined by our experiences at a given moment in time, but also by what we have experienced in our immediate past. Here, we investigated whether such sequential effects influence the affective appraisal of food images. Participants from 16 different countries (N = 1278) watched a randomly presented...

Feedback of physiological responses have a great potential to support virtual training paradigms aimed to increase cognitive task performance under stressful threatening conditions. In the current study, we examined the sensitivity of a range of physiological indicators derived from electrodermal activity (EDA), blood pressure (BP) and heart...

Emotional state during food consumption is expected to affect food pleasantness. We hypothesize that a negative emotional state reduces food pleasantness and more so for novel foods than for familiar foods because novel foods have not yet been associated with previous emotions. Furthermore, we expect this effect to be stronger when judging the...

Interpersonal EEG synchrony derived from the hyperscanning technique has the potential to reveal brain mechanisms beyond the border of traditional analysis within an individual subject. However, the inter-brain connectivity has not been fully investigated using wearable consumer-grade EEG devices which can enable a variety of application in a...

Introduction: he main purpose of this study was to investigate the overall relation between the mean (at the nomothetic or group level) subjective valence and arousal ratings for odors. Although well established in other sensory modalities (e.g., visual, auditory, gustatory, tactile), this relation has not previously been investigated for odors...

Immersive 360◦ virtual reality (VR) movies can effectively evoke a wide range of different emotional experiences. To this end, they are increasingly deployed in entertainment, marketing and research. Because emotions influence decisions and behavior, it is important to assess the user’s affective appraisal of immersive 360◦ VR movies. Knowledge...

Measuring psychophysiological signals of adolescents using unobtrusive wearable sensors may contribute to understanding the development of emotional disorders. This study investigated the feasibility of measuring high quality physiological data and examined the validity of signal processing in a school setting. Among 86 adolescents, a total of...

Measuring concurrent changes in autonomic physiological responses aggregated across individuals (Physiological Synchrony - PS) can provide insight into group-level cognitive or emotional processes. Utilizing cheap and easy-to-use wearable sensors to measure physiology rather than their high-end laboratory counterparts is desirable. Since it is...

Implicit approach-avoidance tendencies can be measured by the approach-avoidance task (AAT). The emergence of mobile variants of the AAT enable its use for both in-the-lab and in-the-field experiments. Within the food domain, use of the AAT is concentrated in research on eating disorders or healthy eating and is seldom used as an implicit...

The conference has been rescheduled from May 2020 to October 2021. However, some delegates needed a publication before October 2021, for example to graduate for their PhD. So we have made a first volume of the Proceedings for those authors. Those papers have been blind peer-reviewed and assessed by the program committee (many thanks to all the...

Peripheral physiological measures such as electrodermal activity (EDA), heart rate and pupil dilation, as well as neurophysiological measures such as electroencephalography (EEG), can inform us about individuals’ cognitive and emotional state. We are interested in exploiting such measures in real life situations. A challenge of interpreting...

Physiological measures such as brain potentials as measured through electroencephalography (EEG), skin conductance or electrodermal activity (EDA) and heart rate can be informative of individuals’ attentional engagement. We are interested in exploiting such measures in real life situations. A challenge of interpreting physiological signals as...

We are interested in monitoring physiology out of the lab because of its potential informative value about mental state, such as stress. For real life studies or applications utilizing physiology, we need to equip individuals with wearables that are designed to be compatible with individuals performing their daily activities, which can come at...

Interpersonal physiological synchrony (PS), or the similarity of physiological signals between individuals over time, may be used to detect attentionally engaging moments in time. We here investigated whether PS in the electroencephalogram (EEG), electrodermal activity (EDA), heart rate and a multimodal metric signals the occurrence of...

Remote control of robots generally requires a high level of expertise and may impose a considerable cognitive burden on operators. A sense of embodiment over a remote-controlled robot might enhance operators? task performance and reduce cognitive workload. We want to study the extent to which different factors affect embodiment. As a first step,...

OBJECTIVE: Concurrent changes in physiological signals across multiple listeners (physiological synchrony-PS), as caused by shared affective or cognitive processes, may be a suitable marker of selective attentional focus. We aimed to identify the selective attention of participants based on PS with individuals sharing attention with respect to...
