About 4% of all prisoners can be diagnosed with a psychotic disorder, but it is largely unknown how these prisoners function during imprisonment. The present study aimed to describe symptoms of psychotic prisoners during imprisonment and incidents caused by them as well as care provided to these prisoners. A total of 61 prisoners were observed for a maximum of 12 weeks. Results show that poverty of speech and blunted affect significantly decreased over time. The largest group of psychotic prisoners either did not suffer from positive psychotic symptoms or the encountered positive psychotic symptoms exhibited a steady or decreasing pattern during their imprisonment. Reasons for these findings still remain unclear.

Sports advertisements such as the Super Bowl showcase products and brands that have invested increasingly large sums financially to gain viewers’ attention. However, how audio features in advertisements impact viewers' behavior remains unexplored.

Using the lens of signaling theory, this research uses advanced data analytics of voice and music audio in Super Bowl advertisements to examine its impacts on viewers.

Results show that advertisement viewers prefer more voiced frames and have a greater liking behavior of voiced frames with a low intensity (less loud) and a higher F1 frequency, which is typically associated with male vocal tracts. A fast music tempo works better for longer advertisements. The model controls for various types of ad appeals. The research underlines the importance of voice and music in signaling successful brand features that are likely to increase the ad-liking behavior of consumers (positive effect).

The current research implies that brands advertising through sports ads must carefully select voice actors and music in order to provide the most positive signals for a brand to have the most significant effect and, thus, a greater return on the high sums invested in the ads.

First, this research contributes in terms of a new research process for using audio analytics in advertising. The detailed research process outlined can be used for future research examining audio and music from advertisements. Second, our findings provide additional support to the important role of voice features (e.g. intensity and frequency) as signals in inducing responses from consumers (Biswas et al., 2019; Hagtvedt and Brasel, 2016). Third, the study surfaces a new theoretical association: the effect of tempo in moderating the relationship between duration and propensity to like an ad.
