Abstract: The purpose of this research is to determine if recall of the same stimuli produces similar emotional reactions as the initial response. Humans experience involuntary and voluntary responses when encountered with a stimulus. Facial expressions are the natural way to deduce and interpret the emotional state of that person. Specialized software called iMotions biometric […]

Abstract: Our previous research found that a combination of sensory attribute intensity and emotional responses helps in achieving better understanding of consumer acceptance and preference for basic taste solutions. By applying this finding to beverage samples, this study aimed to develop an optimum model of predicting either overall liking or preference of vegetable juice products […]

Abstract: The $4.7 billion acquisition of Smithfield Foods by China’s Shuanghui International (now WH Group) marks the largest Chinese takeover of a US company in history. Using electroencephalography along with an incentive compatible willingness‐to‐pay (WTP) elicitation mechanism, our study provides neural based evidence that the Shuanghui–Smithfield acquisition lowered consumers’ preference for the Smithfield brand, but […]

Abstract: This study assessed whether olfactory familiarization can render food odors more pleasant, and consequently food more attractive, to children with autism spectrum disorder. Participants were first presented with a series of food odors (session 1). Then, they were familiarized on four occasions (time window: 5 weeks) with one of the two most neutral odors (the […]

Background: Sympathetic arousal response due to rewarding emotion may not be considered threat to the well-being but such arousal response evoked by fear or punishment can be stressful. When such changes are recorded in lab as biological signals, induced with appropriate stimulus, the observed response may serve as a good indicator of homeostatic alteration. In […]

Abstract: The goal of this study was to examine 38 undergraduate and graduate students’ note taking and summarizing, and the relationship between emotions, the accuracy of those notes and summaries, and proportional learning gain, during learning with MetaTutor, an ITS that fosters self-regulated learning while learning complex science topics. Results revealed that students expressed both […]

Abstract: Affect inextricably plays a critical role in the learning process. In this study, we investigate the multimodal fusion of facial, keystrokes, mouse clicks, head posture and contextual features for the detection of student’s frustration in an Affective Tutoring System. The results (AUC=0.64) demonstrated empirically that a multimodal approach offers higher accuracy and better robustness […]

Abstract: Abnormal processing of emotional information and regulation are core trait-related features of bipolar disorder (BD) but evidence from behavioural studies is conflicting. This study aimed to investigate trait-related abnormalities in emotional reactivity and regulation in BD using novel sensitive behavioural measures including facial expressions and eye movements. Fifteen patients with BD in full or […]

Abstract: While labor issues and quality assurance in crowdwork are increasingly studied, how annotators make sense of texts and how they are personally impacted by doing so are not. We study these questions via a narrative-sorting annotation task, where carefully selected (by sequentiality, topic, emotional content, and length) collections of tweets serve as examples of […]

Abstract: Multimodal sentiment analysis is a core research area that studies speaker sentiment expressed from the language, visual, and acoustic modalities. The central challenge in multimodal learning involves inferring joint representations that can process and relate information from these modalities. However, existing work learns joint representations by requiring all modalities as input and as a […]
