Valence and arousal

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. Mori suggests that this state is characterized by a sense of strangeness and personal disquiet and, when experienced more intensely, by revulsion and disgust. Attention to the originally untested UVH has been spurred by recent progress in robotics and computer graphics technologies in the realistic simulation of aspects of human appearance and behavior and, therefore, by interest in understanding the impact of enhanced anthropomorphic realism on affective experience e. But empirical support for the predicted uncanny effect has been inconsistent e. This has led to the query as to how research should now best proceed Zlotowski et al. To move beyond this seeming impasse, some of the reasons for inconsistency in findings and new avenues of approach can be considered. Illustration of the Uncanny Valley Hypothesis.

Visual search for a socially defined feature: what causes the search asymmetry favoring cross-race faces?

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.

The circumplex model of affect proposes that all affective states arise from cognitive interpretations of core neural sensations that are the product of two independent neurophysiological systems. This model stands in contrast to theories of basic emotions, which posit that a discrete and independent neural system subserves every emotion. We propose that basic emotion theories no longer explain adequately the vast number of empirical observations from studies in affective neuroscience, and we suggest that a conceptual shift is needed in the empirical approaches taken to the study of emotion and affective psychopathologies. The circumplex model of affect is more consistent with many recent findings from behavioral, cognitive neuroscience, neuroimaging, and developmental studies of affect. Moreover, the model offers new theoretical and empirical approaches to studying the development of affective disorders as well as the genetic and cognitive underpinnings of affective processing within the central nervous system. The reigning experimental paradigm in affective neuroscience research posits that emotions can be divided into discrete and independent categories and that specific neural structures and pathways subserve each of these emotional categories.

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.
