Eye movements in scene perception while listening to slow and fast music

To date, there is insufficient knowledge of how visual exploration of outdoor scenes may be influenced by the simultaneous processing of music. Eye movements during viewing various outdoor scenes while listening to music at either a slow or fast tempo or in silence were measured. Significantly shorter fixations were found for viewing urban scenes compared with natural scenes, but there was no interaction between the type of scene and the acoustic conditions. The results revealed shorter fixation durations in the silent control condition in the range 30 ms, compared to both music conditions but, in contrast to previous studies, these differences were non-significant. Moreover, we did not find differences in eye movements between music conditions with a slow or fast tempo. It is supposed that the type of musical stimuli, the specific tempo, the specific experimental procedure, and the engagement of participants in listening to background music while processing visual information may be important factors that influence attentional processes, which are manifested in eye-movement behavior.

Sharing musical expression through embodied listening: a case study based on Chinese guqin music

In this study we report on the result of an experiment in which a guqin music performance was recorded and individual listeners were asked to move their arm along with the music that they heard. Movement velocity patterns were extracted from both the musician and the listeners. The analysis reveals that the listeners’ movement velocity patterns tend to correlate with each other, and with the movement velocity patterns of the player’s shoulders.The findings support the hypothesis that listeners and player share, to a certain degree, a sensitivity for musical expression and its associated corporeal intentionality

Analysis of two methods of isometric muscle contractions during the anti-G straining maneuver

This study investigated the difference in Mean Arterial Pressure (MAP) and Cardiac Output (CO) between two methods of isometric muscle contractions during the Anti-G Straining Maneuver (AGSM). 12 subjects (ages 18 to 38 yrs, height 176.8 +/- 7.4 cm, body mass 78.8 +/- 15.6 kg, percent body fat 14.3 +/- 6.6%) participated in the study. The study was a one-way within-subject design with test conditions counterbalanced. Two methods of isometric muscle contractions lasting 30 seconds each were assessed; an isometric push contraction and an isometric muscle tensing contraction. The dependent parameters were MAP and CO. The average MAP during the push contraction was 123 mmHg, SD +/- 11 and for tense was 118 mmHg, SD +/- 8. CO was 7.6 L/min, SD +/- 1.6 for push and 7.9 L/min, SD +/- 2.0 for tense method. Dependent t-tests revealed t(11) = 1.517, p = 0.157 for MAP and t(11) = 0.875, p = 0.400 for CO. This study demonstrated that the two methods of isometric muscle contractions were not statistically different with regards to MAP and CO. Therefore, both forms of isometric contractions may be potentially useful when performing the muscle contraction portion of the AGSM
