AbstractHuman emotions are complex and constructed of multiple facets of separable components. Amongst many models of emotions, circumplex model of emotion is one of a major theory. The use of the circumplex model allows us to model variable aspects of emotion; however, such momentary expression of one's internal mental state still lacks to consider another, the third dimension of time. Here, we provide an exploratory attempt to build a three-axial model of human emotion to model one of our

Electroencephalography (EEG) was recorded from 28 young adult participants while they mentalized upcoming emotional pictures. Three auditory tones were used as indicative cues, predicting the likelihood of valence of upcoming picture, either positive, negative, or unknown. While seeing an image, participants judged its emotional valence during the task, and subsequently rated their subjective experiences on valence, arousal, and expectation immediately after the experiment. The collected EEG data were then analyzed to determine contributory neural signature for each of three axes. As was expected, a three axial model revealed considerable contribution of the third dimension over the classical two-dimension model. Distinctive contributing EEG components for each axis have been determined. The resultant model is provided as a novel model of 'brain-emotion-interface'. Limitations and applicability of this method are discussed.

Using appropriate stimuli to evoke emotions is especially important for researching emotion. Psychologists have provided several standardized affective stimulus databases-such as the International Affective Picture System (IAPS) and the Nencki Affective Picture System (NAPS) as visual stimulus databases, as well as the International Affective Digitized Sounds (IADS) and the Montreal Affective Voices as auditory stimulus databases for emotional experiments. However, considering the limitations
more » ... the existing auditory stimulus database studies, research using auditory stimuli is relatively limited compared with the studies using visual stimuli. First, the number of sample sounds is limited, making it difficult to equate across emotional conditions and semantic categories. Second, some artificially created materials (music or human voice) may fail to accurately drive the intended emotional processes. Our principal aim was to expand existing auditory affective sample database to sufficiently cover natural sounds. We asked 207 participants to rate 935 sounds (including the sounds from the IADS-2) using the Self-Assessment Manikin (SAM) and three basic-emotion rating scales. The results showed that emotions in sounds can be distinguished on the affective rating scales, and the stability of the evaluations of sounds revealed that we have successfully provided a larger corpus of natural, emotionally evocative auditory stimuli, covering a wide range of semantic categories. Our expanded, standardized sound sample database may promote a wide range of research in auditory systems and the possible interactions with other sensory modalities, encouraging direct reliable comparisons of outcomes from different researchers in the field of psychology. Keywords Emotion . Affective auditory stimuli . Affective ratings . International Affective Digitized Sounds . SAM Emotion, as one of the most significant issues in psychology and psychophysiology, has been thoroughly examined in the field of cognitive psychology (Lindquist, 2010) . For a complete understanding of emotional processes, it is especially important to select appropriate experimental materials that complement the experimental purposes appropriately (for a review, see Gerdes, Wieser, & Alpers, 2014) . In daily human life, the various types of external stimulus that we receive across different modalities not only have powerful effects on subjective senses and evoked emotions (e.g., Fazio, 2001; Jaquet, Danuser, & Gomez, 2012; Marin, Gingras, & Bhattacharya, 2012) but also influence our decision-making and subsequent behavior (mood management theory; Zillmann, 1988). Therefore, many standardized affective stimulus databases were provided and have been extensively used in studies on emotion. The emotional processes have been intensively studied particularly in the visual system. In many psychological and neuroimaging studies, visual stimuli have been used to evoke

Achieving clear visibility through a windshield is one of the crucial factors in manufacturing a safe and comfortable vehicle. The optic flow (OF) through the windshield has been reported to divert attention and could impair visibility. Although a growing number of behavioral and neuroimaging studies have assessed drivers' attention in various driving scenarios, there is still little evidence of a relationship between OF, windshield shape, and driver's attentional efficacy. The purpose of this

Methods: First, we quantified the OF across the windshield in a simulated driving scenario with either of two types of the windshield (a tilted or vertical pillar) at different speeds (60 km/h or 160 km/h) and found more upward OF along the tilted pillar than along the vertical pillar. Therefore, we hypothesized that the predominance of upward OF around the windshield along a tilted pillar could distract a driver and that we could observe the corresponding neural activity. Magnetic resonance scans were then obtained while the subjects performed a visual detection task while watching the driving scene used in the OF analysis. The subjects were required to press a button as rapidly as possible when a target appeared at one of five positions (leftmost, left, center, right, and rightmost). Results: We found that the reaction time (RT) on exposure to a tilted pillar was longer than that on exposure to a vertical pillar in the leftmost and rightmost conditions. Furthermore, there was more brain activity in the precuneus when the pillar was tilted than when it was vertical in the rightmost condition near the pillar. In a separate analysis, activation in the precuneus was found to reflect relative changes in the amount of upward OF when the target was at the rightmost position. Conclusions: Overall, these observations suggest that activation in the precuneus may reflect extraneous cognitive load driven by upward OF along the pillar and could distract visual attention. The findings of this study highlight the value of a cognitive neuroscientific approach to research and development in the motor vehicle manufacturing industry.
