Measuring hedonic impact in animals and infants: microstructure of affective taste reactivity patterns

Berridge, K·2000·Neuroscience & Biobehavioral Reviews

Abstract

The hedonic impact of taste is reflected in affective facial reactions made by human infants, other primates, and even rats. Originally studied in human infants, affective reactions to taste have also been used by affective neuroscience to identify hedonic brain systems in studies of animals (via application of neural stimulation, pharmacological activation, and neural lesion manipulations). The chief limitation of measuring affective reactions is that it is difficult for experimenters to know how to interpret them, and therefore how to interpret changes produced by brain manipulations. This paper notes guidelines to interpretation. It examines the phylogenetic continuity between humans, other primates, and rats in terms of the microstructure of taste-elicited affective reactions. It reviews evidence that affective taste reactivity patterns truly reflect a 'core hedonic process' of palatability or affect, rather than being an ingestion measure, consummatory behavior measure, or a sensory reflex measure. It reviews affective neuroscience studies of taste reactivity that have identified true hedonic brain substrates, and discriminated them from false hedonic brain substrates. It considers the neural bases of incentive 'wanting' versus 'liking'. Finally, it notes the difference between human subjective affective ratings of pleasure and 'core hedonic processes' reflected by behavioral affective reactions.

  • One of the few specific test paradigms for core liking/aversion in animals is measurement of positive and negative orofacial expressions when tasting pleasurable or aversive stimuli.

    “In animals, only the subconscious components of pleasure (Berridge's core “liking”) and aversion are experimentally accessible, and one of the few specific test paradigms is measurement of positive and negative orofacial expressions when tasting pleasurable (typically sweet) or aversive stimuli ([11](#B11)).”

  • Expression of the characteristic happy face when tasting sweets appears to be neurologically organized within the brainstem.

    “As demonstrated in the decerebrate rat ([70](#B70)) and anencephalic baby ([171](#B171)), expression of the characteristic happy face when tasting sweets ([11](#B11), [13](#B13)) appears to be neurologically organized within the brainstem”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
