Role of subjective and objective measures of cognitive processing during learning in explaining the spatial contiguity effect
Abstract: The main objective of this study was to investigate the potential of combining subjective and objective measures of learning process to uncover the mechanisms underlying the spatial contiguity effect in multimedia learning. The subjective measures of learning process were self-reported cognitive load ratings and the objective measures were eye-tracking and EEG measures. Learning outcome […]

Contrasting Divergent and Convergent Thinking by Electroencephalography and Eye Tracking
Abstract: The present study explores the adoption of electroencephalography and eye tracking to assess physiological differences between divergent and convergent thinking. In neuroscientific literature alpha power synchronization in the right parietal lobe has been associated to top-down inhibition of task-irrelevant cognitive processes occurring during divergent thinking, but findings in oculometric studies seem to suggest a […]

Using Sequence Mining to Analyze Metacognitive Monitoring and Scientific Inquiry based on Levels of Efficiency and Emotions during Game-Based Learning
Abstract: Self-regulated learning conducted through metacognitive monitoring and scientific inquiry can be influenced by many factors, such as emotions and motivation, and are necessary skills needed to engage in efficient hypothesis testing during game-based learning. Although many studies have investigated metacognitive monitoring and scientific inquiry skills during game-based learning, few studies have investigated how the […]

The Forensic biometric analysis of changes in facial response provoked by emotional arousal during initial and subsequent exposure to stimuli
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 […]

Using both emotional responses and sensory attribute intensities to predict consumer liking and preference toward vegetable juice products
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 […]

US consumer reactions to China Shuanghui acquisition of Smithfield Foods and its neural basis
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 […]

Effects of familiarization on odor hedonic responses and food choices in children with autism spectrum disorders
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 […]

Galvanic Skin Response as a Simple Physiology Lab Teaching Tool- An Alternative Indicator of Sympathetic Arousal
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 […]

How Are Students’ Emotions Associated with the Accuracy of Their Note Taking and Summarizing During Learning with ITSs?
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 […]

Investigating multimodal affect sensing in an Affective Tutoring System using unobtrusive sensors
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 […]
