Valence and arousal

Thank you for visiting nature.

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.

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.

Information about the affective meanings of words is used by researchers working on emotions and moods, word recognition and memory, and text-based sentiment analysis. Three components of emotions are traditionally distinguished: valence the pleasantness of a stimulus , arousal the intensity of emotion provoked by a stimulus , and dominance the degree of control exerted by a stimulus. We extended that database to nearly 14, English lemmas, providing researchers with a much richer source of information, including gender, age, and educational differences in emotion norms. As an example of the new possibilities, we included stimuli from nearly all of the category norms e. Hinojosa, N. Graham G. Scott, Anne Keitel, … Sara C.

According to several researchers, core affect lies at the foundation of our affective lives and may be characterized as a consciously accessible state combining arousal activated-deactivated and valence pleasure-displeasure. The interaction between these two dimensions is still a matter of debate. All things being equal, the higher the arousal, the more a given stimulus would be experienced as pleasant or unpleasant. While marshaling some preliminary evidence in favor of this hypothesis, we also show how it might be relevant in reframing our conception of depressive disorders i.

However, recent attempts to localize them onto neural bases revealed sparse mappings see for instance Lindquist et al. It is also worth noting that, as Satpute et al.

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. Results: Positive emotions were judged to occur more often than negative emotions in everyday life.

Stimulus-category competition, inhibition, and affective devaluation: a novel account of the uncanny valley. A relationship of this kind would imply valence and arousal being quadratically related and this weak but consistent relationship between the two dimensions has been confirmed in behavioural studies for words: e. Significant relationships are evident in bilateral superior temporal gyri, inferior frontal gyri, hippocampi, medial orbitofrontal, superior frontal gyri and midcingulum. Alexithymia is also something that can be improved with practice! Fridlund, A. Franz, G. Garcia-Marques, T. Neural systems supporting interoceptive awareness. Article Google Scholar Coburn, A. Each participant provided written informed consent before participating in the experiment. How are affective word ratings related to lexico-semantic properties?

A practice pre-test of five trials was applied, as described for the tasks of Experiment 1. Typically, the reading of emotionally-laden words in studies requiring implicit processing of their emotional content evokes activity within a set of brain regions that include the amygdala Herbert et al. The top left panel of Fig. Mutual facilitation of response latencies. Presti, P. Our results suggest that the representations of valence and arousal are in part underpinned by sensory specific brain areas, the temporal voice areas, but also by brain areas e. Gallese, V. Though relating to affective experience, the poor specification of this concept has resulted in much debate and various renderings of its meaning, with the investigation of the UVH and shinwakan in terms of constructs such as pleasantness, comfort level, eeriness, familiarity i.
