  • Validating Physiological Stress Detection Model Using Cortisol as Stress Bio Marker


    Abstract: In this work, we have presented the validation of a stress detection model using cortisol as the stress biomarker. The proposed model uses two physiological signals: Galvanic Skin Response (GSR) and Photoplethysmograph (PPG) to classify stress into two levels. GSR and PPG signals were collected from a total of 13 participants along with saliva […]

  • Explicit and Implicit Measures in Video Quality Assessment


    Abstract: This work investigates the relation between subjective Video Quality Assessment (VQA) metrics and psychophysiological measures of human interaction assessment such as gaze tracking, electroencephalography and facial expression recognition. Subjective quality assessment is based on deliberate judgement attributions of perceived quality and processes that human perceivers are not consciously aware of. Traditional VQA methods ask […]

  • Framing effective cause-related marketing message online


    Abstract: The purpose of this study is to examine the interaction effect between online Cause-Related Marketing (CRM) advertisements and brand reputation on consumers’ brand evaluation in the hotel industry. Two experimental studies were conducted: (1) a survey-based experiment that demonstrates the moderating role of brand reputation, and (2) a laboratory experiment using psychophysiological measurements of […]

  • Measurements of Galvanic Skin Response on Subjects Affected by Stress


    Abstract: The aim of the present paper is to study the Galvanic Skin Response (GSR) level on subjects affected by stress. The device that we have used, connects to the people by finger electrodes to record GSR. The purpose was to find statistical differences between the activities (mental task, walking, sitting and to fill out […]

  • Towards a conceptual framework for analysing impression management during face-to-face communication


    Abstract: The purpose of this paper is to generate a framework for investigating direct face-to-face interactions during corporate results presentations from senior executives. This is important because face-to-face communications represent opportunities for impression management owing to cognitive biases and constraints arising from the interplay of non-verbal and verbal cues. Our Behavioural Impression Management Framework combines […]

  • Pictorial content, sequence of conflicting online reviews and consumer decision-making: The stimulus-organism-response model revisited


    Abstract: Conflicting online reviews challenge the consumer’s decision-making processes. Furthermore, increase in visual content, both positive and negative, adds complexity. This study analyses conflicting online reviews based on text and photos using automatic processing patterns and conscious perceptions. The study is built on the stimulus-organism-response model revisited by Jacoby (2002), and captures nonlinear eye-tracking data […]

  • PRIME: Block-Wise Missingness Handling for Multi-modalities in Intelligent Tutoring Systems


    Abstract: Block-wise missingness in multimodal data poses a challenging barrier for the analysis over it, which is quite common in practical scenarios such as the multimedia intelligent tutoring systems (ITSs). In this work, we collected data from 194 undergraduates via a biology ITS which involves three modalities: student-system logfiles, facial expressions, and eye tracking. However, […]

  • I Can See It in Your Face. Affective Valuation of Exercise in More or Less Physically Active Individuals


    Abstract: The purpose of this study was to illustrate that people’s affective valuation of exercise can be identified in their faces. The study was conducted with a software for automatic facial expression analysis and it involved testing the hypothesis that positive or negative affective valuation occurs spontaneously when people are reminded of exercise. We created […]

  • The Impact of Contextualized Emotions on Self-Regulated Learning and Scientific Reasoning during Learning with a Game-Based Learning Environment


    Abstract: The goal of this study was to examine college students’ (n = 61) contextualized emotions during in-game actions while playing CRYSTAL ISLAND, a game-based learning environment where students are tasked with solving the mystery of what illness impacted all island inhabitants. We examined emotions during in-game actions: during book reading, after scanning food items for the […]

  • EyeCar: Modeling the Visual Attention Allocation of Drivers in Semi-Autonomous Vehicles


    Abstract: A safe transition between autonomous and manual control requires sustained visual attention of the driver for the perception and assessment of hazards in dynamic driving environments. Thus, drivers must retain a certain level of situation awareness to safely takeover. Understanding the visual attention allocation of drivers can pave the way to inferring their dynamic […]
