Valence And Arousal

This study assesses the influence of valence and arousal of element/landmarks along a route on the spatio-temporal representation of the route itself. Participants watched a movie of a virtual route containing landmarks with high arousal and positive (HP) or negative valence (HN), or landmarks with low arousal and positive (LP) or negative valence (LN). Afterwards, they had to (a) imagine walking distances between landmarks, (b) indicate the position of the landmarks along the route, (c) judge the spatial and temporal length of the route, and (d) draw the route. Results showed that the tasks were differentially influenced by the valence and arousal levels. Specifically, participants were more accurate in representing distances between positive, rather than negative, landmarks and in localizing positive high arousing landmarks. Moreover, the high arousing landmarks improved performance at the route drawing task. Finally, participants in the negative and low arousing conditions judged the route as being metrically and temporally longer than participants in positive and high arousing conditions. These results are interpreted in the light of theories about the effects of emotions on memory processes and the “feelings-as-information” theory. In brief, the results support the idea that representations of a route reflect a combination of cognitive and emotional processes.

The purpose of this study was to investigate the effects of valence and arousal dimensions of music on physiological and subjective recovery from stress, and how these effects might be moderated by trait absorption. In Experiment 1, 40 participants experienced stress after being told to prepare a speech, and then listened to peaceful music or white noise. In Experiment 2, 88 participants experienced stress using the same methodology, and then listened to happy, peaceful, sad or agitated music. Music with a positive valence promoted recovery better than music with a negative valence, and low arousal music was more effective than high arousal music. In both experiments, differences in recovery were largely driven by individuals who were high in absorption.

Valence And Arousal

There is increasing evidence that citizens consume the news because it arouses them. However, to explain the motivated processing of news messages, research usually focuses on negative discrete emotions or the valence dimension of affect. This means that the role of arousal is largely overlooked. In this experiment, conducted in 2019 in Austria, I exposed 191 citizens to a televised news item about immigration—varying the level of threat, while taking physiological measures of negative valence and arousal, followed by self-reported indicators of motivated reasoning. The results indicate that combining the valence and arousal dimensions of affect is the preferred way to understand citizens' reactions to political news. While negative affect predicted motivated reasoning, these effects were much more pronounced for those who experienced high arousal at the same time. Not only does this illuminate some of the black box behind motivated reasoning, the consequences for journalism are profound: the way that journalists cover the news might unwittingly drive citizens apart.

Affective Information

Although studies have investigated the influence of the emotionality of primes on the cross-modal affective priming effect, it is unclear whether this effect is due to the contribution of the arousal or the valence of primes. We explored how the valence and arousal of primes influenced the cross-modal affective priming effect. In Experiment 1 we manipulated the valence of primes (positive and negative) that were matched by arousal. In Experiments 2 and 3 we manipulated the arousal of primes under the conditions of positive and negative valence, respectively. Affective words were used as auditory primes and affective faces were used as visual targets in a priming task. The results suggest that the valence of primes modulated the cross-modal affective priming effect but that the arousal of primes did not influence the priming effect. Only when the priming stimuli were positive did the cross-modal affective priming effect occur, but negative primes did not produce a priming effect. In addition, for positive but not negative primes, the arousal of primes facilitated the processing of subsequent targets. Our findings have great significance for understanding the interaction of different modal affective information.

Watermarking Scheme

Perceptual Watermarking should take full advantage of the results from human visual system (HVS) studies. Just noticeable distortion (JND), which refers to the maximum distortion that the HVS does not perceive, gives a way to model the HVS accurately. An effective Spatio-Temporal JND model guided video watermarking scheme in DCT domain is proposed in this paper. The watermarking scheme is based on the design of an additional accurate JND visual model which incorporates spatial Contrast Sensitivity Function (CSF), temporal modulation factor, retinal velocity, luminance adaptation and contrast masking. The proposed watermarking scheme, where the JND model is fully used to determine scene-adaptive upper bounds on watermark insertion, allows providing the maximum strength transparent watermark. Experimental results confirm the improved performance of the Spatio-Temporal JND model. The authors’ Spatio-Temporal JND model is capable of yielding higher injected-watermark energy without introducing noticeable distortion to the original video sequences and outperforms the relevant existing visual models. Simulation results show that the proposed Spatio-Temporal JND model guided video watermarking scheme is more robust than other algorithms based on the relevant existing perceptual models while retaining the watermark transparency.
