(author)This study investigates how cognitive performance is affected by the combination of two stressors that are operationally relevant for helicopter pilots: heat load and hypobaric hypoxia. Fifteen participants were exposed to: 1) no stressors, 2) heat load, 3) hypobaric hypoxia and 4) combined heat load and hypobaric hypoxia. Hypobaric hypoxia (13...article 2023

(author)We trained a model to distinguish an extreme high arousal, unpleasant drink from regular drinks based on a range of implicit behavioral and physiological responses to naturalistic tasting. The trained model predicted arousal ratings of regular drinks, highlighting the possibility to estimate affective experience without having to rely on...article 2023

Sharan, N.N (author), Toet, A. (author), Mioch, T. (author), Niamut, O. (author), van Erp, J.B.F. (author)Effective interpersonal communication is important to maintain relationships and build trust, empathy, and confidence. In this digital age, communication has become mediated, which filters out many of the social cues that are essential to facilitate interpersonal communication. This paper investigates the extent to which social cues influence...conference paper 2022

Stuldreher, I.V. (author), Merasli, A. (author), Thammasan, N. (author), van Erp, J.B.F. (author), Brouwer, A.M. (author)Research on brain signals as indicators of a certain attentional state is moving from laboratory environments to everyday settings. Uncovering the attentional focus of individuals in such settings is challenging because there is usually limited information about real-world events, as well as a lack of data from the real-world context at hand...article 2022

Hattum, M.T. (author), Huisman, G. (author), Toet, A. (author), van Erp, J.B.F. (author)In recent years, there has been a significant increase in research on mediated communication via social touch. Previous studies indicated that mediated social touch (MST) can induce similar positive outcomes to interpersonal touch. However, studies investigating the user experience of MST technology predominantly involve brief experiments that...article 2022

Stuldreher, I.V. (author), Kaneko, D. (author), Hiraguchi, H. (author), van Erp, J.B.F. (author), Brouwer, A.M. (author)Humans differ strongly in their willingness to try novel foods. Hesitance to try new foods is referred to as food neophobia. Understanding food neophobia is important, as it can be a significant barrier to adopt a healthy, balanced or plant-based diet. We here use electroencephalogram (EEG) recordings to obtain insight in the early attentional...article 2022

van der Burg, E. (author), Toet, A. (author), Brouwer, A.M. (author), van Erp, J.B.F. (author)How we perceive the world is not solely determined by what we sense at a given moment in time, but also by what we processed recently. Here we investigated whether such serial dependencies for emotional stimuli transfer from one modality to another. Participants were presented a random sequence of emotional sounds and images and instructed to...article 2022

van der Burg, E. (author), Toet, A. (author), Brouwer, A.M. (author), van Erp, J.B.F. (author)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...article 2022

Sharan, N.N. (author), Toet, A. (author), Mioch, T. (author), Niamut, O. (author), van Erp, J.B.F. (author)We recently developed the Holistic Social Presence Questionnaire (HSPQ) to measure the quality of mediated social communication experiences. Initial research confirmed the content and face validity of the HSPQ. This study investigates the convergent validity and sensitivity of the HSPQ. Participants completed a decision-making task in groups,...conference paper 2022

However, mediated social communication (MSC) systems will only become a viable alternative for in-person social interactions when they reliably and intuitively convey all relevant social and spatial cues needed by communication partners to establish effective communication,...conference paper 2022

(author)Reflecting the two main prevailing and opposing views on the nature of emotions, emotional responses to food and beverages are typically measured using either (a) a categorical (lexicon-based) approach where users select or rate the terms that best express their food-related feelings or (b) a dimensional approach where they rate perceived food...article 2022

(author)Working memory (WM) is the system responsible for maintaining and manipulating information, in the face of ongoing distraction. In turn, WM span is perceived to be an individual-differences construct reflecting the limited capacity of this system. Recently, however, there has been some evidence to suggest that WM capacity can increase through...article 2022

van Erp, J.B.F. (author)Implicit physiological measures such as heart rate and skin conductance convey information about someone's cognitive or affective state. Currently, gastrointestinal (GI) tract-based markers are not yet considered while both the organs involved as well as the microbiota populating the GI tract are bidirectionally connected to the brain and have a...article 2022

Toet, A. (author), van Erp, J.B.F. (author)Background: In this study we measured the affective appraisal of sounds and video clips using a newly developed graphical self-report tool: the EmojiGrid. The EmojiGrid is a square grid, labeled with emoji that express different degrees of valence and arousal. Users rate the valence and arousal of a given stimulus by simply clicking on the grid....article 2021

Liu, Y. (author), Toet, A. (author), Krone, T. (author), van Stokkum, R. (author), Eijsman, S. (author), van Erp, J.B.F. (author)The affective appraisal of odors is known to depend on their intensity (I), familiarity (F), detection threshold (T), and on the baseline affective state of the observer. However, the exact nature of these relations is still largely unknown. We therefore performed an observer experiment in which participants (N = 52) smelled 40 different odors ...article 2020
