The current studies aimed to find out whether a nonintentional form of mood contagion exists and which mechanisms can account for it. In these experiments participants who expected to be tested for text comprehension listened to an affectively neutral speech that was spoken in a slightly sad or happy voice. The authors found that (a) the emotional expression induced a congruent mood state in the listeners, (b) inferential accounts to emotional sharing were not easily reconciled with the findings, (c) different affective experiences emerged from intentional and nonintentional forms of emotional sharing, and (d) findings suggest that a perception-behavior link (T. L. Chartrand & J. A. Bargh, 1999) can account for these findings, because participants who were required to repeat the philosophical speech spontaneously imitated the target person's vocal expression of emotion.

In 3 experiments, the authors tested the assumption that perceived movements toward a person trigger the approach system and thereby facilitate the processing of positive affective concepts, whereas perceived movements away from a person trigger the avoidance system and thereby facilitate the processing of negative affective concepts. In the 1st study, participants categorized positive words more quickly than negative words while flexing the arm and negative words more quickly than positive words while extending the arm. The 2nd study revealed that positive words were categorized more rapidly than negative words if viewers had the impression that they were moving toward the computer screen, whereas negative words were categorized faster if viewers had the impression that they were moving away from the screen. These findings were replicated in Experiment 3 using a lexical decision task instead of an adjective evaluation task.

Graphitic carbon nitride, g-C3N4, is a promising organic photo-catalyst for a variety of redox reactions. In order to improve its efficiency in a systematic manner, however, a fundamental understanding of the microscopic interaction between catalyst, reactants and products is crucial. Here we present a systematic study of water adsorption on g-C3N4 by means of density functional theory and the density functional based tight-binding method as a prerequisite for understanding photocatalytic water splitting. We then analyze this prototypical redox reaction on the basis of a thermodynamic model providing an estimate of the overpotential for both water oxidation and H(+) reduction. While the latter is found to occur readily upon irradiation with visible light, we derive a prohibitive overpotential of 1.56 eV for the water oxidation half reaction, comparing well with the experimental finding that in contrast to H2 production O2 evolution is only possible in the presence of oxidation cocatalysts.

Dispositional Sensitivity to Befallen Injustice (SBI) is proposed as a new construct. A self-report questionnaire with four types of indicators (frequency, intensity of anger, intrusiveness of thoughts, punitivity) was developed for measuring SB1. Using structural equation modeling and the general rationale of multitrait-multimethod analysis, the convergent and discriminant validity of this questionnaire was investigated vis-d-vis measures for Trait

Drawing on motivational approaches to emotion, the authors propose that the perceived change in spatial distance to pictures that arouse negative emotions exerts an influence on the significance of these pictures. Two experiments induced the illusion that affective pictures approach toward the observer, recede from the observer, or remain static. To determine the motivational significance of the pictures, emotional valence and arousal ratings as well as startle responses were assessed. Approaching unpleasant pictures were found to exert an influence on both the valence and the arousal elicited by the pictures. Furthermore, movement of pleasant or neutral pictures did not influence startle responses, while the second experiment showed that approaching unpleasant pictures elicited enhanced startle responses compared to receding unpleasant pictures. These findings support the view that a change of spatial distance influences motivational significance and thereby shapes emotional responses.
