Perception of emotion in sounded and imagined music

WE STUDIED THE EMOTIONAL RESPONSES BY MUSICIANS to familiar classical music excerpts both when the music was sounded, and when it was imagined.We used continuous response methodology to record response profiles for the dimensions of valence and arousal simultaneously and then on the single dimension of emotionality. The response profiles were compared using cross-correlation analysis, and an analysis of responses to musical feature turning points, which isolate instances of change in musical features thought to influence valence and arousal responses. We found strong similarity between the use of an emotionality arousal scale across the stimuli, regardless of condition (imagined or sounded). A majority of participants were able to create emotional response profiles while imagining the music, which were similar in timing to the response profiles created while listening to the sounded music.We conclude that similar mechanisms may be involved in the processing of emotion in music when the music is sounded and when imagined.

Perception of mode, rhythm, and contour in unfamiliar melodies: Effects of age and experience

We explored the ability of older (60-80 years old) and younger (18-23 years old) musicians and nonmusicians to judge the similarity of transposed melodies varying on rhythm, mode, and/or contour (Experiment 1) and to discriminate among melodies differing only in rhythm, mode, or contour (Experiment 2). Similarity ratings did not vary greatly among groups, with tunes differing only by mode being rated as most similar. In the same/different discrimination task, musicians performed better than nonmusicians, but we found no age differences. We also found that discrimination of major from minor tunes was difficult for everyone, even for musicians. Mode is apparently a subtle dimension in music, despite its deliberate use in composition and despite people's ability to label minor as "sad" and major as "happy."

Perception of non-invasive ventilation in adult Swiss intensive care units

The real utilisation scenario of non-invasive ventilation (NIV) in Swiss ICUs has never been reported. Using a survey methodology, we developed a questionnaire sent to the directors of the 79 adult ICUs to identify the perceived pattern of NIV utilisation. We obtained a response rate of 62%. The overall utilisation rate for NIV was 26% of all mechanical ventilations, but we found significant differences in the utilisation rates among different linguistic areas, ranging from 20% in the German part to 48% in the French part (p <0.01). NIV was mainly indicated for the acute exacerbations of COPD (AeCOPD), acute cardiogenic pulmonary edema (ACPE) and acute respiratory failure (ARF) in selected do-not-intubate patients. In ACPE, CPAP was much less used than bi-level ventilation and was still applied in AeCOPD. The first line interface was a facial mask (81%) and the preferred type of ventilator was an ICU machine with an NIV module (69%). The perceived use of NIV is generally high in Switzerland, but regional variations are remarkable. The indications of NIV use are in accordance with international guidelines. A high percentage of units consider selected do-not-intubate conditions as an important additional indication.

The Effect of Weight on the Perception of Political Candidates

Chris Christie recently visited the famous “Wailing Wall” in Jerusalem, Israel, during his first trip abroad as governor of New Jersey. The New York Post reported on his trip with the headline “The Whale at the Wall” (Campanile 2012). Given headlines like this, it is easy to see anecdotal evidence of the stigmatization that surrounds obesity within contemporary American society. What’s more important is that these social stigmas that Americans are faced with every day are not merely surface level jokes bantered about for a cheap laugh. They are often prejudices that permeate every aspect of human life. Whether it comes to finding a date, looking for a job, or trying to be taken serious by one’s peers, weight is always a topic of concern. In an effort to understand how far entrenched these biases are in society, this thesis studies the ramifications of obesity in politics. In this thesis, I attempt to understand to what extent, if any, obesity matters in regard to candidate appearance, voters' choices, and political behavior.

Physiological correlates of aesthetic perception of artworks in a museum

Arts experts are commonly skeptical of applying scientific methods to aesthetic experiencing, which remains a field of study predominantly for the humanities. Laboratory research has however indicated that artworks may elicit emotional and physiological responses. Yet, this line of aesthetics research has previously suffered from insufficient external validity. We therefore conducted a study in which aesthetic perception was monitored in a fine-art museum, unrestricting to the viewers’ freedom of aesthetic choice. Visitors were invited to wear electronic gloves through which their locomotion, heart rate and skin conductance were continuously recorded. Emotional and aesthetic responses to selected works of an exhibition were assessed using a customized questionnaire. In a sample of 373 adult participants, we found that physiological responses during perception of an artwork were significantly related to aesthetic-emotional experiencing. The dimensions ‘Aesthetic Quality’, ‘Surprise/Humor’, ‘Dominance’ and ‘Curatorial Quality’ were associated with cardiac measures (heart rate variability, heart rate level) and skin conductance variability. This is first evidence that aesthetics can be statistically grounded in viewers’ physiology in an ecologically valid environment, the art gallery, enhancing our understanding of the effects of artworks and their curatorial staging.
