Journal ArticleDOI
Neural representation of olfactory mixtures in the honeybee antennal lobe
TL;DR: Although a gain control system in the honeybee antennal lobe prevents saturation of the olfactory system, mixture representation follows essentially elemental rules.
Journal ArticleDOI
Configural Olfactory Learning in Honeybees: Negative and Positive Patterning Discrimination
TL;DR: Olfactory conditioning of PER was used to study whether, beyond elemental associations, honeybees are able to process configural associations, and whether the ratio between the number of presentations of the reinforced stimuli and theNumber of presentation of the nonreinforced stimuli affects discrimination.
Journal ArticleDOI
Stimulus coding in human associative learning: flexible representations of parts and wholes.
TL;DR: Evidence that human learning is representationally flexible in a way that challenges both configural and elemental theories is reviewed, and research showing that task demands, prior experience, instructions, and stimulus properties all influence whether a particular problem is solved configurally or elementally is described.
Journal ArticleDOI
Positive and negative patterning in human classical skin conductance response conditioning
Harald Lachnit,H. D. Kimmel +1 more
TL;DR: It was concluded that the assumed unique cue constituted a learned “rule,” and that the actual elemental stimuli were neither perceptually nor otherwise modified during the conditioning process.
Journal ArticleDOI
A modified version of the unique cue theory accounts for olfactory compound processing in honeybees
TL;DR: Honeybees were not able to differentiate reinforced from nonreinforced stimuli in Experiment 1, but in Experiment 2, differentiation between the single odorant A and the ternary compound developed more easily than between the binary compound BC and ABC.
