Testing for Individual Differences in the Identification of Chemosignals for Fear and Happy: Phenotypic Super-Detectors, Detectors and Non-Detectors

摘要: Mood odor identification, explicit awareness of mood odor, may be an important emotion skill and part a complex dual processing system. It has already been shown that odors have significant implicit effects, effects occur without awareness. This study applies methods for examining human individual differences in the identification chemosignals fear happy, itself, key to understanding olfactory Axillary had collected from 14 male donors during induction task. Pads were after 12 24 minutes, creating two doses. Sixty -one participants (41 females) identified chemosignals. On single trial, 2 doses fear, sterile control. There 15 trials. The first analysis (rtt) showed population was phenotypically heterogeneous, not homogeneous, accuracy. also minimum 10 trials needed test reliability. second analysis, Growth Mixture Modeling, found three distinct groups detectors: (1) 49.49% consistently accurate super detectors, (2) 32.52% above chance level (3) 17.98% non-detectors. Bayesian Posterior Analyses reliability at or 98%. No related valence (fear happy), dose (collection minutes) gender found. Implications further genetic differences, learning function are noted. appears many people can reliable explicitly identifying happy but this is homogeneous.
