Infant Acceptance of Primary Tastes and Fat Emulsion: Developmental Changes and Links with Maternal and Infant Characteristics.

abstract：:Past research has shown that odor perception can be affected by how we label odors. The aim of this study was to expand on previous work by investigating the impact of labels on edibility, pleasantness, and intensity ratings as well as on reaction times when detecting labeled odors. We tested 50 subjects. Five odorant...

abstract：:The role of odors in the long-distance navigation of birds has elicited intense debate for more than half a century. Failure to resolve many of the issues fueling this debate is due at least in part to the absence of controls for a variety of non-specific effects that odors have on the navigational process.
