Number comparison under the Ebbinghaus illusion
Frontiers in Psychology, 2022 A series of studies show interest in how visual attributes affect the estimate of object numbers in a scene. In comparison tasks, it is suggested that larger patches are perceived as more numerous.

Human sensitivity to gearshift loads [PDF]
, 2001 This paper describes an investigation of the ability of humans to distinguish different levels of gearlever load. A test rig with a forward-backward moving gearshift lever was constructed using the typical interior dimensions of European B segment ...

Viewpoint-invariant Weber fractions and standard contour-curvature discrimination [PDF]
Biological Cybernetics, 1993 It is proposed that any cue for the visual discrimination of shape, in particular the discrimination of curved contours, should be such that the perceptual relationships defined by the cue are invariant under changes in observer viewpoint. Such relationships may be quantified by the Weber fraction; that is, the ratio Δc/c, where, for any particular ...

Droplet size distribution in homogeneous isotropic turbulence [PDF]
, 2011 We study the physics of droplet breakup in a statistically stationary homogeneous and isotropic turbulent flow by means of high resolution numerical investigations based on the multicomponent lattice Boltzmann method.

Extraction of the neural count function from the Weber fraction [PDF]
The Journal of the Acoustical Society of America, 1986 It is shown that the dependence of the Weber fraction, ΔI/I, on I determines the form of the neural firing rate function N(I) provided that the relation between ΔN and N is given. Here, ΔN is the change in average firing rate resulting from an intensity jnd. The firing rate function consistent with Weber's law is predicted when ΔN ∼ N1/2. Assuming that

On the edge: haptic discrimination of edge sharpness. [PDF]
PLoS ONE, 2013 The increasing ubiquity of haptic displays (e.g., smart phones and tablets) necessitates a better understanding of the perceptual capabilities of the human haptic system.

Derivation of Del180 from sediment core log data\u27 Implications for millennial-scale climate change in the Labrador Sea [PDF]
, 2001 Sediment core logs from six sediment cores in the Labrador Sea show millennial-scale climate variability during the last glacial by recording all Heinrich events and several major Dansgaard-Oeschger cycles.

Malleability of the approximate number system: effects of feedback and training
Frontiers in Human Neuroscience, 2012 Prior research demonstrates that animals and humans share an approximate number system (ANS), characterized by ratio dependence and that the precision of this system increases substantially over human development. The goal of the present research was to

Dependence of the drag over super hydrophobic and liquid infused surfaces on the textured surface and Weber number [PDF]
, 2018 Direct Numerical Simulations of a turbulent channel flow have been performed. The lower wall of the channel is made of staggered cubes with a second fluid locked in the cavities.
