The scent of attraction and the smell of success: crossmodal influences on person perception

Charles Spence
2021 Cognitive Research  
Numerous peer-reviewed studies have documented that a variety of olfactory stimuli, from ambient malodours through to fine fragrances, and even a range of chemosensory body odours can influence everything  ...  At the same time, however, it is important to note that the presence of scent (and/or the absence of malodour) can also influence people's (i.e., a perceiver's) self-confidence which may, in turn, affect  ...  Using functional MRI, Seubert et al. (2010a) were able to demonstrate that the processing of disgusted faces was facilitated by the prior presentation of odour primes.  ...

The human amygdala and the emotional evaluation of sensory stimuli

David H. Zald
2003 Brain Research Reviews  
A wealth of animal data implicates the amygdala in aspects of emotional processing.  ...  In recent years, functional neuroimaging and neuropsychological studies have begun to refine our understanding of the functions of the amygdala in humans.  ...  Note that at this resolution (which is typical of anatomical MRIs collected as part of functional studies), it is difficult to visualize the borders of the subnuclei or even the border of the amygdala  ...
