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.     

IN DEFENSE OF PUBLICS: PROJECTION,BIAS, AND CULTURAL NARRATIVES IN SCIENCE AND RELIGION DEBATES

John H. Evans's recent book Morals Not Knowledge is a timely argument to recognize broader social and cultural factors that might impact what U.S. religious publics think about the relationship between science and religion and their attitudes toward science and/or religion. While Evans's focus is primarily on what can be classed as moral issues, this response argues that there are other factors that sit within neither the older epistemic conflict model approach nor a moral conflict model approach that also merit further investigation. There is a significant need for further research that examines the social, psychological, (geo)political, and broader cultural factors shaping people's social identities in relation to science and religion debates. When undertaking such research, we need to be wary of creating a binary between scholarly and public space discourse. Social scientific research in this field should be led by public perceptions, attitudes, and views, not by concepts or frameworks that we project onto them.     

Reflective practice and work-based research: a description of micro- and macro-reflective cycles

The role and importance of reflective practice have been thoroughly documented and its benefits are well established. When coupled with research in a higher education context, a similar importance for reflection can be extended to professional development, leadership, and work-based learning. However, the relation of reflective practice to work-based research, specifically when defined as an element of methodology in higher degree research awards, has yet to be fully examined. In this paper, we explore the basic principles of reflective practice as they relate to work-based learning and highlight the interfaces or ‘bridges’ between reflective cycles, showing their centrality to work-based research. As an example of how these principles might be applied, we also introduce the role of each micro- and macro-reflective cycle in the Professional Studies program at University of Southern Queensland, a relatively new academic approach which utilises both work-based learning and work-based research.     

The metaphysics of goodness in the ethics of Aristotle

Kraut (Against absolute goodness. Oxford University Press, Oxford, 2011) and other neo-Aristotelians have argued that there is no such thing as absolute goodness. They admit only good in a kind, e.g. a good sculptor, and good for something, e.g. good for fish. What is the view of Aristotle? Mostly limiting myself to the Nicomachean Ethics (NE), I argue that Aristotle is committed to things being absolutely good and also to a metaphysics of absolute goodness where there is a maximally best good that is the cause of the goodness of all other things in virtue of being their end. I begin (in Sect. 2) by suggesting that the notion of good as an end, which is present in the first lines of the NE, is not obviously accounted for by good in a kind or good for something. I then give evidence that good in a kind (in Sect. 3) and good for something (in Sect. 4) can explain neither certain distinctions drawn between virtues nor the determinacy ascribed to what is good “in itself.” I argue (in Sect. 5) contra Gotthelf (2012) that because several important arguments in the Nicomachean Ethics rely on comparative judgments of absolute value—e.g. “Man is the best of all animals”—Aristotle is committed to the existence of both absolute goodness and an absolutely best being. I focus (in Sect. 6) on one passage, Aristotle’s division of goods in NE I 12, which presupposes this metaphysical picture.     

Describing Trajectories of Homeless Service Use in Hawai‘i Using Latent Class Growth Analysis

The State of Hawai‘i, like many other areas across the United States, has large numbers of individuals and families experiencing homelessness, many of whom seek support through statewide shelters and services. This study explored the diversity of ways in which individuals and families moved through Hawai‘i's homeless service system. Using administrative data, a cohort of new service users was tracked across time to trace the developmental trajectories of their homeless service use. The sample consisted of adults who had entered the service system for the first time in the fiscal year (FY) of 2010 (N = 4655). These individuals were then tracked through the end of FY 2014, as they used emergency shelter, transitional shelter, and outreach services. A latent class growth analysis was conducted and identified four distinct patterns of service use: low service use (n = 3966, 85.2%); typical transitional shelter use (n = 452, 9.7%); atypical transitional use (n = 127, 2.7%), and potential chronic service use (n = 110, 2.4%). Multinomial logistic regression models were then used to determine if select demographic, family, background experience (e.g., education, employment), or health variables were associated with class membership. The distinct profiles for class membership are discussed.     

Introduction to the special issue on the intersection of professional selling and service

As organizational operations continue to evolve in response to increasing customer demands, frontline research has begun to consider how traditionally separate organizational functions may be complementary to firm performance. Specifically, as sales and service activities become increasingly intertwined within the frontline role, this special issue explores how the sales and service functions interact within an organization. The articles contained in this special issue consider the interaction of sales and service with respect to customer, employee, and firm outcomes. After introducing evolving thought in the area, we provide an overview of five articles that make up this special issue. We conclude by offering additional areas of research.     

Cardiac morbidity risk and depression and anxiety: a disorder, symptom and trait analysis among cardiac surgery patients

The aim of this study was to examine depression and anxiety disorders and their characteristic symptoms (anhedonia/low positive affect and anxious arousal, respectively), along with measures of state negative affect (NA) and Type D personality, in relation to cardiac surgery related morbidity. Patients awaiting elective coronary artery bypass graft surgery (n=158; 20.9% female; 11.4% concomitant valve surgery; age M=64.7, SD=10.6) underwent the structured MINI International Neuropsychiatric Interview to determine current affective disorders. Patients also completed the Mood and Anxiety Symptom Questionnaire and a measure of Type D personality traits. Postoperative cardiac morbidity was confirmed after surgery during the index hospitalization and included stroke,renal failure, ventilation>24 h, deep sternal wound infection, reoperation, arrhythmia and 30-day mortality at any location (n=59, 37.3% of total). After adjustment for age, recent myocardial infarction, heart failure, hypertension, urgency of surgery and time spent on cardiopulmonary bypass generalized anxiety disorder was associated with cardiac morbidity (odds ratio [OR]=3.26, 95% confidence interval [CI] 1.10-9.67, p=0.03). Adjusted analysis of personality traits revealed the NA component of Type D personality was associated with cardiac morbidity (OR=1.07, 95% CI 1.01-1.14, p=0.03). The Mood and Anxiety Symptom Questionnaire subscales were not associated with increased morbidity risk. Affective disorders, affective phenotypes, and personality traits were differentially associated with post-cardiac surgery morbidity outcomes independent of cardiac surgery morbidity risk factors. Concurrent investigation of depression and anxiety with respect to cardiac outcomes warrants further research.     

Differential Genetic and Environmental Influences on Reactive and Proactive Aggression in Children

While significant heritability for childhood aggression has been claimed, it is not known whether there are differential genetic and environmental contributions to proactive and reactive forms of aggression in children. This study quantifies genetic and environmental contributions to these two forms of aggression in an ethnically diverse urban sample of 9–10 year old twins (N = 1219), and compares results across different informants (child self-report, mother, and teacher ratings) using the Reactive–Proactive Aggression Questionnaire (RPQ). Confirmatory factor analysis of RPQ items indicated a significant and strong fit for a two-factor proactive–reactive model which was significantly superior to a one-factor model and which replicated across gender as well as the three informant sources. Males scored significantly higher than females on both self-report reactive and proactive aggression, findings that replicated on mother and teacher versions of the RPQ. Asian–Americans scored lower than most ethnic groups on reactive aggression yet were equivalent to Caucasians on proactive aggression. African–Americans scored higher than other ethnic groups on all measures of aggression except caregiver reports. Heritable influences were found for both forms of aggression across informants, but while boys’ self-reports revealed genetic influences on proactive (50%) and reactive (38%) aggression, shared and non-shared environmental influences almost entirely accounted for girls’ self-report reactive and proactive aggression. Although genetic correlations between reactive and proactive aggression were significant across informants, there was evidence that the genetic correlation was less than unity in boys self reported aggression, indicating that genetic factors differ for proactive and reactive aggression. These findings provide the first evidence for varying genetic and environmental etiologies for reactive and proactive aggression across gender, and provide additional support for distinction between these two forms of aggression.     

Attentional mechanisms associated with repressive distancing

This research explores the role of attentional shift and disengagement in repressive distancing. During a target-detection task in which emotional and neutral facial expressions were used as cues, participants received performance feedback intended to elicit a negative emotional reaction that rendered the task either threatening or not threatening to self-concept. When the task was perceived to threaten self-concept, repressors distanced themselves by rapidly disengaging their attention from the facial expressions rather than by slowly shifting or not shifting their attention to the facial expressions. Attentional disengagement was accompanied by sympathetic nervous system activity suggestive of a defense response. This research provides further insight into the nature and consequences of the interplay of dispositional tendencies, situational contexts, and higher order cognitive influences in attentional behavior.
