The present study examined the structure of Bryant's Empathy Index (BEI) using different samples for conducting exploratory and confirmatory analyses. The BEI was administered to a sample of 2,714 children (mean age 11.12, SD = 1.59). Exploratory and confirmatory factor analyses showed a three-factor structure: Feelings of Sadness, Understanding Feelings and Tearful Reaction. The results revealed both the multidimensionality of the instrument and appropriate fit indices for the model proposed. Although these results were very similar to those reported in other studies with a Spanish population, the analyses were conducted in a more robust way: with a larger sample and using polychoric correlations and cross validation estimation.

From 1990 to 1999 MTV promoted a series of 288 music videos called “Buzz Clips”, designed to highlight emerging artists and genres. Such promotion had a measurable impact on an artists’ earnings and record sales. To date, the kinds of musical and visual practices MTV promoted have not been quantitatively analyzed. Just what made some videos Buzzworthy, and others not? We applied two phases of content analysis to this corpus to determine the most common sonic and visual signifiers in Buzz Clips, then processed the results of that content analysis using polychoric correlations. Our findings show high degrees of shared variance between certain pairs of musical and visual elements observed in the sample music videos. We interpret a number of these relationships in terms of their relevance to a performer’s perceived ethnicity and gender, showing how certain audiovisual features regularly accompany white men (e.g., electric guitar) while others regularly accompany women and performers of color (e.g. drum machines).
