Aesthetics is a kind of advanced psychological activity that involves high-level cognitive processing and emotional experience. To understand its essence, one of the premises is to reveal the mechanism of mental representation of artistic works. Previous studies believed that visual processing was the base of aesthetic activities. Recently, it has been found that the visual system represents a visual scene in a hierarchical structure, which provides a new perspective to explore the relationship between visual processing and aesthetic feelings. This research examines the role of the hierarchical characteristics of the mental representation in producing aesthetic feeling of visual images. At the beginning, the subjects were asked to divide the blank rectangle freely to obtain the prior structural parameters. In the other two experiments, the subjects were presented with two groups of pictures generated by prior parameters and the pictures generated by random parameters, and then reported which group looks more beautiful. We found that, no matter simple Mondrian style pictures, or complex sand table scenes and virtual three-dimensional scenes, subjects prefer images that conform to the priori hierarchy. The above findings indicate that visual hierarchy preference has cognitive function basis and provide inspirations for establishing a more perfect aesthetic cognitive model and developing artificial intelligence with automatic design and evaluation capabilities.

67467 | Risk Analysis of Newspaper Articles Based on the First and Second Language of an Individual

Newspapers are a medium that spreads awareness about current day events; based on which individuals make decisions. The current study focuses on decisions made by individuals - in regard to the Foreign Language Effect (FLE) - in their day-to-day life. Literature around FLE make note of an emotional-rational response among participants and we wanted to cross check those predictions in real life situations with the use of newspaper articles. Bilinguals will be used to examine the participants response to risk analysis on the event of motor vehicle accidents. This will be done with the help of 3 articles in English on the aforementioned theme. The study will analyze if decisions made by an individual after reading the article in English will differ based on their first language. The Independent Variable will be the Native Language and the Dependent Variable will be the Response Provided. We predict that individuals whose foreign/second language is English will respond in a risk aversive manner. As there are comparatively fewer research papers on FLE and motor accidents with a participant pool of those between 18 to 25 years, this paper will add to pre-existing research and can be a base from which future researchers can build on.

68976 | Musician Effects on the Perception of Speech With Degraded Fundamental Frequency Contours in Noisy Environments

Pitch variations of the fundamental frequency (F0) contour contributes critical information to encoding speech under noisy environments. Recent evidence suggests that musicians may confer an advantage on speech-in-noise perception due to enhanced F0 pitch discrimination abilities. However, previous studies compared speech with natural-F0 and flattened-F0 contours (i.e., monotone pitch), leaving the effects contributed from different levels of F0 contours unexamined. This study investigates whether a musician advantage exists in understanding Mandarin Chinese speech where the F0 pitch contour is degraded at different levels (i.e., conveying tone and/or intonation information). To this end, we systematically flattened the F0 contour either at the tone level, intonation level, or all levels of F0 contour pitch information to assess musician effects on speechin-noise perception. A cohort of sixteen musicians and 17 non-musicians identified degraded-F0 Mandarin Chinese sentences masked under noise at four signal-to-noise ratios (no noise, 0, −5, and −9 dB). Pitch difference thresholds and innate musical skills associated with speech-in-noise benefits were also assessed. While speech intelligibility decreased with decreasing signal-to-noise levels for both musicians and non-musicians, we found no musician advantage in identifying any type of flattened-F0 contour speech in noise. Musicians demonstrated smaller (better) pitch discrimination thresholds, which correlated with better perception of flat-intonation speech. In addition, higher speech intelligibility was associated with better performance on innate musical skills on pitch and accent processing. These findings suggest that speech-in-noise benefits may not be contingent on the ability to process F0 pitch contours, and could instead be related to innate musical skills.

69229 | Accuracy of Measuring Physical Activity Parameters Using Apple Watch: A Comprehensive Review

Background: This study examined the accuracy of commercial wearable devices (e.g., Apple Watch) in measuring physical activity at different intensities by comprehensively reviewing the literature. Methods: Two electronic databases, including Google Scholar, and PubMed, were searched up to June 2022. Selection criteria included: (1) Studies were conducted using Apple Watch as a tool for measuring physical activity parameters (such as time spent in sedentary behavior, light-intensity, and moderate to high-intensity physical activities); (2) An objective instrument such as an accelerometer was utilized for checking the accuracy of physical activity measurements. Exclusion criteria: (1) Studies did not examine the validation of any physical activity parameter; (2) Studies did determine the intensity of physical activity. Results: A total of 13 studies met the inclusion criteria (sedentary behavior [n=1], light activity [n=5], and moderate to high-intensity activity [n=12]);. Among the included 13 studies, Apple Watch was validated for sedentary behavior in one study (1/1), light activity (four out of five), and moderate-to-high intensity activity (ten out of twelve), respectively. Conclusion: The evidence showed that most of the included studies suggest the Apple Watch is acceptable and for accurately measuring physical activity at different intensities. And it can be used not only as an instrument for self-health management but also as a tool for monitoring the prevalence of physical activity in large-scale populations.
