DOI: 10.1007/s00221-017-5025-1
Abstract: A number of studies have reported that grasps and manual estimations of differently sized target objects (e.g., 20 through 70 mm) violate and adhere to Weber’s law, respectively (e.g., Ganel et al. 2008a, Curr Biol 18:R599–R601)—a… read more here.

Biomechanical constraints do not influence pantomime-grasping adherence to Weber’s law: A reply to Utz et al. (2015)

DOI: 10.1016/j.visres.2016.09.018
Abstract: ABSTRACT Work by our group and others employed the within‐participants variability in peak grip aperture as a ‘just‐noticeable‐difference’ (JND) in grasping. Notably, our group reported that grasping responses with decoupled spatial relations between stimulus and… read more here.

DOI: 10.1038/s41593-019-0439-7
Abstract: Although Weber’s law is the most firmly established regularity in sensation, no principled way has been identified to choose between its many proposed explanations. We investigated Weber’s law by training rats to discriminate the relative… read more here.

DOI: 10.1038/s41598-017-06799-4
Abstract: According to Weber’s law, a fundamental principle of perception, visual resolution decreases in a linear fashion with an increase in object size. Previous studies have shown, however, that unlike for perception, grasping does not adhere… read more here.

Visual complexity of egg patterns predicts egg rejection according to Weber's law

DOI: 10.1098/rspb.2022.0710
Abstract: Visual complexity is ubiquitous in nature. Drivers of complexity include selection in coevolutionary arms races between antagonists. However, the causes and consequences of biological complexity and its perception are largely understudied, partly because complexity is… read more here.

Grasping follows Weber's law: How to use response variability as a proxy for JND
Sign Up to like & getrecommendations! Published in 2022 at "Journal of Vision"
DOI: 10.1167/jov.22.12.13
Abstract: Weber's law is a fundamental psychophysical principle. It states that the just noticeable difference (JND) between stimuli increases with stimulus magnitude; consequently, larger stimuli should be estimated with larger variability. However, visually guided grasping seems… read more here.

DOI: 10.5840/jphil2019116621
Abstract: In the 1980s, a number of philosophers argued that perception is analog. In the ensuing years, these arguments were forcefully criticized, leaving the thesis in doubt. This paper draws on Weber’s Law, a well-entrenched finding… read more here.
