Decoding emotions in expressive music performances: A multi-lab replication and extension study

With over 560 citations reported on Google Scholar by April 2018, a publication by Juslin and Gabrielsson (1996) presented evidence supporting performers’ abilities to communicate, with high accuracy, their intended emotional expressions in music to listeners. Though there have been related studies published on this topic, there has yet to be a direct replication of this paper. A replication is warranted given the paper’s influence in the field and the implications of its results. The present experiment joins the recent replication effort by producing a five-lab replication using the original methodology. Expressive performances of seven emotions (e.g. happy, sad, angry, etc.) by professional musicians were recorded using the same three melodies from the original study. Participants (N?=?319) were presented with recordings and rated how well each emotion matched the emotional quality using a 0–10 scale. The same instruments from the original study (i.e. violin, voice, and flute) were used, with the addition of piano. In an effort to increase the accessibility of the experiment and allow for a more ecologically-valid environment, the recordings were presented using an internet-based survey platform. As an extension to the original study, this experiment investigated how musicality, emotional intelligence, and emotional contagion might explain individual differences in the decoding process. Results found overall high decoding accuracy (57%) when using emotion ratings aggregated for the sample of participants, similar to the method of analysis from the original study. However, when decoding accuracy was scored for each participant individually the average accuracy was much lower (31%). Unlike in the original study, the voice was found to be the most expressive instrument. Generalised Linear Mixed Effects Regression modelling revealed that musical training and emotional engagement with music positively influences emotion decoding accuracy.     

Does Cooperation in the Laboratory Reflect the Operation of a Broad Trait?

The Dictator Game, a face valid measure of altruism, and the Trust Game, a face valid measure of trust and trustworthiness, are among the most widely used behavioural measures in human cooperation research. Researchers have observed considerable covariation among these and other economic games, leading them to assert that there exists a general human propensity to cooperate that varies in strength across individuals and manifests itself across a variety of social settings. To formalize this hypothesis, we created an S‐1 bifactor model using 276 participants' Dictator Game and Trust Game decisions. The general factor had significant, moderate associations with self‐reported and peer‐reported altruism, trust, and trustworthiness. Thus, the positive covariation among economic games is not reducible to the games' shared situational features. Two hundred participants returned for a second session. The general factor based on Dictator Game and Trust Game decisions from this session did not significantly predict self‐reported and peer‐reported cooperation, suggesting that experience with economic games causes them to measure different traits from those that are reflected in self‐assessments and peer‐assessments of cooperativeness. © 2018 European Association of Personality Psychology

Social Integration may Moderate the Relationship between Neighborhood Vacancy and Mental Health Outcomes: Initial Evidence from Flint,Michigan

Long-term residence in neighborhoods is thought to promote the development and maintenance of supportive relationships and trust. These strong social ties may, however, be limited in communities in post-industrial cities characterized by high levels of vacant properties. This study aimed to examine the relationship between neighborhood vacancy and mental health with adjustment for length of residence and possible moderation by social (dis)integration in a sample of Flint, MI, residents. We found that short-term (but not long-term) increases in neighborhood vacancy were associated with poorer mental health, after adjustment for individual covariates. When considering neighborhood vacancy, length of residence and individual covariates, however, the only significant association detected was between higher social disintegration and lower wellbeing. This effect was direct and not mediated by other factors. In this way, it appears that the social conditions of neighborhoods may be important, particularly in places that have experienced declines in the built environment. In addition, we identified evidence that social integration moderates the relationship between neighborhood vacancy and mental health outcomes. The level of neighborhood vacancies had a weaker relationship to wellbeing among those with higher levels of social ties. But none of the independent variables in our study were able to predict social integration, highlighting some potential areas for future research. From these findings, we posit that establishing strong social connections can buffer residents against negative mental health outcomes, and health promotion efforts could usefully assist in maintaining social ties among neighbors.

     

Power and perceived influence: I caused your behavior,but I'm not responsible for it

There are numerous examples of powerful people denying responsibility for others' (mis)conduct in which they played—and acknowledge playing—a causal role. The current article seeks to explain this conundrum by examining the difference between, and powerful people's beliefs about, causality and responsibility. Research has shown power to have numerous psychological consequences. Some of these consequences, such as overconfidence, are likely to increase an individual's belief that he or she caused another person's behavior. However, others, such as decreased perspective‐taking, are likely to decrease an individual's belief that he or she was responsible for another person's behavior. In combination, these psychological consequences of power may lead powerful people to believe that they instigated another's behavior while simultaneously believing that the other person could have chosen to do otherwise. The dissociation between these two attributions may help to explain why people in positions of power often deny responsibility for others' behavior—unethical or otherwise—that they undeniably caused.

On the examination couch: the relationship between the egocentric perspective and the attentional focus

Determined by anatomical characteristics, the binocular visual field has an elliptical shape. Whereas the focus of attention – that area of the visual field in which objects can be consciously perceived – is significantly smaller, its shape is not necessarily dependent on the same factors. Indeed, it is yet unknown if the maximum extents of the attentional focus’ meridians are dimensionally stable or adapt to the egocentric perspective. In this study, we intended to measure the expansion up to which peripheral stimuli can still be perceived while participants were sitting and lying on the left and on the right body side. Results demonstrate that contrary to the visual field the maximum extents along the attentional focus’ meridians remain stable across different head positions with a greater horizontal than vertical alignment. This indicates that the expansion ratios of the meridians of the attentional focus are not dependent on the egocentric perspective. Rather, they appear stable in space and gravity-based. Findings are discussed in terms of our visual environment and current as well as alternative interpretations are weighed against each other.
