Effect of early experience on food preferences
Bělová, Magdalena ; Exnerová, Alice (advisor) ; Landová, Eva (referee)
Experience influence food preferences, in some species early experience influence food preference more than other factors. This influence was found in different species from different taxons. It's linked to a sensitive period which suggest that it might be food imprinting. In some cases it is difficult to distinguish imprinting from neophobia or associative learning. That is one of the reasons why autors often use the term primacy effect or just early experience. In different experiments different stimuli are imprinted. There are taste stimuli, visual stimuli, olfactoric stimuli and tactile stimuli. All of them can influence the later food preferences. Intensity and persistence differs in various species. Diverse metodics complicates comparison of these phenomena. Social transmission also influences food preferences of youngs in some species, but in the most cases it's more about deactivation of neophobia. Key words: early experience, food preferences, food imprinting, primacy effect, social transmission of food preferences, social learning Powered by TCPDF (www.tcpdf.org)
