Music perception [PDF]

open access: yesFrontiers in Bioscience, 1979
The state of knowledge in several areas of music perception will be reviewed. Topics to be covered include principles of organization and grouping, tonal shape analyzing mechanisms, rhythm, and tempo, the role of memory, and the perception of instrumental timbre. The field as a whole is currently undergoing rapid expansion. This is due in large part to

Tracking with spatial constrained coding

open access: yesIET Computer Vision, 2015
A video tracking method based on spatial constrained coding (SCC) is proposed in this study. To characterise local image structure information, the dense scale‐invariant feature transform (SIFT) descriptor is extracted for each pixel in the image.

Pitch Perception [PDF]

open access: yesAttention, Perception & Psychophysics, 2008
This article is a review of the psychophysical study of pitch perception. The history of the study of pitch has seen a continual competition between spectral and temporal theories of pitch perception. The pitch of complex stimuli is likely based on the temporal regularities in a sound's waveform, with the strongest pitches occurring for stimuli with ...

Psychosocial Outcomes in Patients With Endocrine Tumor Syndromes: A Systematic Review

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction The combination of disease manifestations, the familial burden, and varying penetrance of endocrine tumor syndromes (ETSs) is unique. This review aimed to portray and summarize available data on psychosocial outcomes in patients with ETSs and explore gaps and opportunities for future research and care.

Perceptual Training in Ice Hockey: Bridging the Eyes-Puck Gap Using Virtual Reality

open access: yesSports Medicine - Open
Background Some cognitive and perceptual determinants of sports performance can be arduous to train using conventional methods. In ice-hockey, this is the case for the players’ ability to identify the largest exposed area (LEA), i.e., the goal area that ...
