Chicks like consonant music

The question of whether preference for consonance is rooted in acoustic properties important to the auditory system or is acquired through enculturation has not yet been resolved. Two-month-old infants prefer consonant over dissonant intervals, but it is possible that this preference is rapidly acquired through exposure to music soon after birth or in utero. Controlled-rearing studies with animals can help shed light on this question because such studies allow researchers to distinguish between biological predispositions and learned preferences. In the research reported here, we found that newly hatched domestic chicks show a spontaneous preference for a visual imprinting object associated with consonant sound intervals over an identical object associated with dissonant sound intervals. We propose that preference for harmonic relationships between frequency components may be related to the prominence of harmonic spectra in biological sounds in natural environments.     

Healthy Lifestyle,Well-being,Physical Activity,Sport, and Scholastic/academic Performance: Interactions and Connections

The physical activity and sport are key elements for a healthy lifestyle. However, a little-investigated element is the presence of a possible relationship between school or academic performance and the participation in physical activity and sport in groups of preadolescents and adolescents. In order to clarify the complex relationship between mind and body in preadolescence and adolescence, the present discussion investigates the causal and direct relationship between sport activity and performance; and describes how this relationship can be mediated by the sense of self-esteem and self-efficacy; and investigates the relationship between group sports practice and school or academic performance.
