The main prediction of the Uncanny Valley Hypothesis UVH is that observation of humanlike characters that are difficult to distinguish from the human counterpart will evoke a state of negative affect. LPP and EMG provided direct psychophysiological indices of affective state during passive observation and the SAM provided self-reported indices of affective state during explicit cognitive evaluation of static facial stimuli. The results provide no support for the notion that category ambiguity along the DHL is specifically associated with enhanced experience of negative affect. On the contrary, the LPP and SAM-based measures of arousal and valence indicated a general increase in negative affective state i. In conclusion, this multi-method approach using well-validated psychophysiological and self-rating indices of arousal and valence rejects — for passive observation and for explicit affective evaluation of static faces — the main prediction of the UVH. The longstanding Uncanny Valley Hypothesis UVH predicts that difficulty distinguishing a realistic humanlike character or object e.

A growing body of literature shows that the emotional content of verbal material affects reading, wherein emotional words are given processing priority compared to neutral words. Human emotions can be conceptualised within a two-dimensional model comprised of emotional valence and arousal intensity. These variables are at least in part distinct, but recent studies report interactive effects during implicit emotion processing and relate these to stimulus-evoked approach-withdrawal tendencies. The aim of the present study was to explore how valence and arousal interact at the neural level, during implicit emotion word processing. The emotional attributes of written word stimuli were orthogonally manipulated based on behavioural ratings from a corpus of emotion words. Results showed greater neural activation within right insular cortex in response to stimuli evoking conflicting approach-withdrawal tendencies i. Further, a significant cluster of activation in the left extra-striate cortex was found in response to emotional than neutral words, suggesting enhanced perceptual processing of emotionally salient stimuli. These findings support an interactive two-dimensional approach to the study of emotion word recognition and suggest that the integration of valence and arousal dimensions recruits a brain region associated with interoception, emotional awareness and sympathetic functions. Several theoretical models of emotion have been proposed, including amongst others, models which propose a small number of universal underlying emotional states, i. Dimensional models suggest that emotion is best understood as occurring within a dimensional space, most commonly a two-dimensional space spanning valence and arousal. Emotional valence describes the extent to which an emotion is positive or negative, whereas arousal refers to its intensity, i.

To investigate how architectural design impacts individuals' affective states, we measured subjective judgments of perceived valence pleasant and unpleasant and arousal after the dynamic experience of a progressive change of macro visuospatial dimensions of virtual spaces. To this aim, we developed a parametric model that allowed us to create 54 virtual architectural designs characterized by a progressive change of sidewalls distance, ceiling and windows height, and color of the environment.

In the current study we sought to complement this characterization by investigating the frequency of emotions in human everyday communication, which may be crucial information for designing new diagnostic or intervention tools to test and improve emotion recognition. Methods: One hundred healthy German individuals were asked to indicate the valence and arousal of 62 emotion words in a questionnaire. Importantly, participants were additionally asked to indicate the frequency with which they experience each emotion themselves and observe it in others.

Several theories conceptualise emotions along two main dimensions: valence a continuum from negative to positive and arousal a continuum that varies from low to high. These dimensions are typically treated as independent in many neuroimaging experiments, yet recent behavioural findings suggest that they are actually interdependent. This result has impact on neuroimaging design, analysis and theoretical development. We were interested in determining the extent of this interdependence both behaviourally and neuroanatomically, as well as teasing apart any activation that is specific to each dimension.
