Evolutionary cognitive neuroscience Evolutionary Psychology – ISSN 1474-7049 – Volume 5(1). The sense of taste is stimulated when nutrients or other chemical compounds activate specialized receptor cells within the oral cavity. PLAY. Hence, the organism learns a taste aversion. Conditioned taste aversion (CTA) is the most well-studied form of taste-visceral learning, whereby normally positive (or neutral) appetitive and/or consummatory responses to a taste stimulus are replaced with avoidance and rejection responses, following its association with a negative visceral consequence [8–10].

That being said, taste aversion is an incredibly powerful force inside your brain that literally controls how the entire body feels. The findings that strong taste aversions could be acquired after only one pairing of a taste with illness, that tastes compared to other external cues seemed to be selectively associated with illness, and that taste-illness associations could be formed over long delays, violated what others believed to be the laws of learning. In its broad sense, the term “evolutionary psychology” stands for any attempt to adopt an evolutionary perspective on human behavior by supplementing psychology with the central tenets of evolutionary biology. Evolutionary Psychology: Learning, Biology, and the Brain. This video is part of an online course, Intro to Psychology. Modern evolutionary psychology. Latent Inhibition. Early hominoids sought nutrition within a closed tropical forest environment, probably eating mostly fruit and leaves, and early hominids left this environment for the savannah and greatly expanded their dietary repertoire. Taste Aversion. nomenon of taste aversion learning. Human taste abilities have been shaped, in large part, by the ecological niches our evolutionary ancestors occupied and by the nutrients they sought. Evolutionary psychology and dynamical systems theory have both been proposed as antidotes to the theoretical fragmentation that long characterized the field of psychology. Shereen Lehman, MS, is a healthcare journalist and fact checker. I. Human’s evolved in an environment where food supplies were not constant and therefore sweet, fatty or salty foods would have been valued as they are vital requirements for the body.

Taste learning, and particularly conditioned taste aversion (CTA), is an adaptive learning involving complex brain mechanisms and molecular pathways. Human taste abilities have been shaped, in large part, by the ecological niches our evolutionary ancestors occupied and by the nutrients they sought. … Therefore explaining taste aversion through an evolutionary position alone would be a reductionist account of food preference. Or does the answer seem obvious: "Bitter foods taste bad." Consequent neural activity in taste nerves and taste-related areas of the brain lead to gustatory sensation and perception.

A powerful disinclination toward eating or drinking certain substances. Taste helps us decide what to eat and influences how efficiently we digest these foods.
