The Physical Activity Scale for the Elderly (PASE): development and evaluation.
Washburn RA, Smith KW, Jette AM, Janney CA. Washburn RA, et al. J Clin Epidemiol. 1993 Feb;46(2):153-62. doi: 10.1016/0895-4356(93)90053-4. J Clin Epidemiol. 1993. PMID: 8437031 Clinical Trial.
Item weights for the PASE were derived by regressing a physical activity principal component score on responses to the PASE. The component score was based on 3-day motion sensor counts, a 3-day physical activity dairy and a global activity self-assessment. ...

Motion clouds: model-based stimulus synthesis of natural-like random textures for the study of motion perception.
Leon PS, Vanzetta I, Masson GS, Perrinet LU. Leon PS, et al. J Neurophysiol. 2012 Jun;107(11):3217-26. doi: 10.1152/jn.00737.2011. Epub 2012 Mar 14. J Neurophysiol. 2012. PMID: 22423003 Free article.
Choosing an appropriate set of stimuli is essential to characterize the response of a sensory system to a particular functional dimension, such as the eye movement following the motion of a visual scene. Here, we describe a framework to generate random texture movie …

Spatial phase and frequency in motion capture of random-dot patterns.
Ramachandran VS, Inada V. Ramachandran VS, et al. Spat Vis. 1985;1(1):57-67. doi: 10.1163/156856885x00080. Spat Vis. 1985. PMID: 3940050
A square matrix of spots (A) was presented in rapid alternation with an uncorrelated matrix (B). If the square arrays are superimposed spatially one sees random incoherent motion. However, incoherent motion was seen only if the outer edges were exactly aligne …

Random dot motion stimuli are more sensitive than light stimuli for detection of visual field loss in ocular hypertension patients.
Wall M, Jennisch CS. Wall M, et al. Optom Vis Sci. 1999 Aug;76(8):550-7. doi: 10.1097/00006324-199908000-00024. Optom Vis Sci. 1999. PMID: 10472961
Motion size threshold is defined as the smallest circular area within which dot motion is detected. ...CONCLUSIONS: Using a size thresholding technique in ocular hypertension patients, random dot motion stimuli appear to be more sensitive than luminanc …

Perception of complex motion in humans and pigeons (Columba livia).
Nankoo JF, Madan CR, Spetch ML, Wylie DR. Nankoo JF, et al. Exp Brain Res. 2014 Jun;232(6):1843-53. doi: 10.1007/s00221-014-3876-2. Epub 2014 Feb 26. Exp Brain Res. 2014. PMID: 24570385
We used random-dot stimuli to investigate pigeons' ability to detect complex motion (radial, rotation, and spiral) compared to humans. Our human participants had a significantly lower threshold for rotational and radial motion when compared to spiral motio …

Electrically tunable collective motion of dissipative solitons in chiral nematic films.
Shen Y, Dierking I. Shen Y, et al. Nat Commun. 2022 Apr 19;13(1):2122. doi: 10.1038/s41467-022-29831-2. Nat Commun. 2022. PMID: 35440645 Free PMC article.
From the motion of fish and birds, to migrating herds of ungulates, collective motion has attracted people for centuries. ...Driven by external electric fields, hundreds of directrons are generated in a chiral nematic film. They start with random motions …

Residual motion perception in a "motion-blind" patient, assessed with limited-lifetime random dot stimuli.
Baker CL Jr, Hess RF, Zihl J. Baker CL Jr, et al. J Neurosci. 1991 Feb;11(2):454-61. doi: 10.1523/JNEUROSCI.11-02-00454.1991. J Neurosci. 1991. PMID: 1992012 Free PMC article.
A neurological patient (L.M.) suffering a specific loss of visual motion perception (Zihl et al., 1983) due to extrastriate cortical damage was studied using random dot "limited-lifetime" stimuli with a direction discrimination task. With a stimulus like that of New …

Drift-balanced random stimuli: a general basis for studying non-Fourier motion perception.
Chubb C, Sperling G. Chubb C, et al. J Opt Soc Am A. 1988 Nov;5(11):1986-2007. doi: 10.1364/josaa.5.001986. J Opt Soc Am A. 1988. PMID: 3210090
Here we show how to construct counterexamples: visual stimuli that are consistently perceived as obviously moving in a fixed direction yet for which Fourier-domain power analysis yields no systematic motion components in any given direction. We provide a general theoretica …

Collective motion enhances chemotaxis in a two-dimensional bacterial swarm.
Tian M, Zhang C, Zhang R, Yuan J. Tian M, et al. Biophys J. 2021 May 4;120(9):1615-1624. doi: 10.1016/j.bpj.2021.02.021. Epub 2021 Feb 23. Biophys J. 2021. PMID: 33636168 Free PMC article.
In a dilute liquid environment in which cell-cell interaction is negligible, flagellated bacteria, such as Escherichia coli, perform chemotaxis by biased random walks alternating between run-and-tumble. In a two-dimensional crowded environment, such as a bacterial swarm, t …

Saccadic suppression of low-level motion.
Shioiri S, Cavanagh P. Shioiri S, et al. Vision Res. 1989;29(8):915-28. doi: 10.1016/0042-6989(89)90106-5. Vision Res. 1989. PMID: 2629207
We measured the detection of motion before, during and after a saccade to explore the effects of a saccade on motion perception. To isolate the low-level motion mechanism, the stimulus was a random-dot field displaced by small distance (0.3 deg) within …
