Comparison of Various Formulas (Hadlock's I and II, Merz, Shepard, Campbell, Wilkin's) to Calculate Birth Weight by Antenatal Ultrasound.
Anirudh RM, Shriram T, Prabhu CS, Ramya P. Anirudh RM, et al. J Pharm Bioallied Sci. 2025 Jun;17(Suppl 2):S1855-S1857. doi: 10.4103/jpbs.jpbs_574_25. Epub 2025 Jun 18. J Pharm Bioallied Sci. 2025. PMID: 40655681 Free PMC article.

Estimated fetal weights using Hadlock's I and II, Merz, Shepard, Campbell, and Wilkin's formulas were compared with actual birth weights. Statistical analysis included paired t-tests, ANOVA, and post hoc Tukey's test, with significance set at P < 0.05. ...Merz and Wilki

Something in the Sway: Effects of the Shepard-Risset Glissando on Postural Activity and Vection.
Mursic RA, Palmisano S. Mursic RA, et al. Multisens Res. 2022 Sep 1;35(7-8):555-587. doi: 10.1163/22134808-bja10081. Multisens Res. 2022. PMID: 36057431
This study investigated claims of disrupted equilibrium when listening to the Shepard-Risset glissando (which creates an auditory illusion of perpetually ascending/descending pitch). ...As expected, vection was stronger during Shepard-Risset glissandi than during wh …

Art and the brain: the influence of art on Roger Shepard's studies of mental rotation.
Levy EK, Levy DE, Goldberg ME. Levy EK, et al. J Hist Neurosci. 2004 Mar;13(1):79-90. doi: 10.1080/09647040490885510. J Hist Neurosci. 2004. PMID: 15370339
This paper explores the influence of visual sources on Roger N. Shepard's 1971 mental rotation experiments and the centrality of ambiguity as one of his experimental and artistic concerns. Sources include Shepard's statements about ambiguity as express …

Shepard's universal law supported by honeybees in spatial generalization.
Cheng K. Cheng K. Psychol Sci. 2000 Sep;11(5):403-8. doi: 10.1111/1467-9280.00278. Psychol Sci. 2000. PMID: 11228912
On the basis of functional analyses of the probabilistic structure of the world, Shepard formulated a universal law of generalization, claiming that generalization gradients, as a function of the appropriately scaled distance of a stimulus from S+, should be exponential in …
