Changes in Odor Sweetness Resulting from Implicit Learning of a Simultaneous Odor-Sweetness Association: An Example of Learned Synesthesia ☆ ☆☆

摘要: Abstract In two experiments the smelled sweetness of odors was increased by using them as flavorants sucrose solution. Experiment 1 used blind experimenters to compare a target odor mixed with control water during masked training trials. The unaffected whether or not subjects revealed some explicit knowledge contingencies in post-conditioning recognition test. 2 found that such conditioned increase occurred solutions were sipped from cup sucked through straw. Using frequency test designed provide sensitive assay contingency awareness, there still no indication this affected conditioning. It concluded modification taste-properties results implicit simultaneous associative learning and provides an example learned synesthesia.
