The Science of Hair Whorls and Laterality Part 3, The Nature Side of Nature/Nurture Early Experience, Debunking the Imprinting Myth

I devote part three of the series to a research study by Séverine Henry, an academic researcher from the University of Rennes, France, entitled Long-Term Effects of Early Intensive Handling of Foals (2009). I wrote this summary for our book, “Genetics and the Behavior of Domestic Animals,” 2nd Edition (2014), Chapter 7, “Genetics and Horse […]
The Science of Hair Whorls and Laterality Part 4, The Nature Side of Nature/Nurture Early Experience, A Non-Intrusive Neonatal Handling Method

Over twenty years, I developed and practiced a non-intrusive neonatal handling procedure on my foals with positive results. This summary is reprinted from Chapter 7, “Genetics and Horse Behavior (Equus caballus)” in “Genetics and the Behavior of Domestic Animals” (2014) Editors Temple Grandin and Mark J. Deesing. A non-intrusive neonatal handling procedure Immediately following birth […]
The Science of Hair Whorls and Laterality Part 5, Lateralization in the Nervous System
Horses are one-sided and prefer to use one eye over another under certain circumstances. Science attributes sensory laterality to processing different information types in one or other of the two brain hemispheres. Generally, horses prefer using the left eye to observe novel objects and humans, and the preference is more marked in emotional situations and […]

The language I used was not scientific because I was not a scientist yet. She was patient in her attempts to disseminate the […]
