Whose nose does not know? Demographical characterization of people unaware of anosmia

PurposeFor functionally anosmic subjects, the sense of smell is basically useless in daily activities—they are unlikely to detect the threatening smell of rotten food, gas or smoke, or to enjoy the flavor of food or the smell of perfumes. Although this appears very distressing, functionally anosmic subjects in our sample seemed not to be aware or bothered with impaired olfaction...

Voice of Authority: Professionals Lower Their Vocal Frequencies When Giving Expert Advice

Acoustic analysis and playback studies have greatly advanced our understanding of between-individual differences in nonverbal communication. Yet, researchers have only recently begun to investigate within-individual variation in the voice, particularly how people modulate key vocal parameters across various social contexts, with most of this research focusing on mating contexts...

Odor lateralization and spatial localization: Null effects of blindness

People can navigate through an environment using different sensory information, including olfactory cues. Correct intranasal localization and external location of odors can be learned, and some people are able to lateralize olfactory stimuli above chance, which raises the question: What determines the spectrum of olfactory localization abilities. Here, we explored whether odor...

A Compensatory Effect on Mate Selection? Importance of Auditory, Olfactory, and Tactile Cues in Partner Choice among Blind and Sighted Individuals

Effects of “trigeminal training” on trigeminal sensitivity and self-rated nasal patency

respiratory rate/depth, changes in nasal secretion, changes in nasal airflow resistance, or sneezing. The nasal trigeminal sensitivity to irritants is higher in Anna Oleszkiewicz and Timo Schultheiss

Voice cues are used in a similar way by blind and sighted adults when assessing women’s body size

Humans’ ability to gauge another person’s body size from their voice alone may serve multiple functions ranging from threat assessment to speaker normalization. However, how this ability is acquired remains unknown. In two experiments we tested whether sighted, congenitally blind and late blind adults could accurately judge the relative heights of women from paired voice stimuli...

Chemical complexity of odors increases reliability of olfactory threshold testing

Assessment of odor thresholds is a widely recognized method of measuring olfactory abilities in humans. To date no attempts have been made to assess whether chemical complexity of odors used can produce more reliable results. To this end, we performed two studies of repeated measures design with 121 healthy volunteers (age 19–62 years). In Study 1, we compared thresholds obtained...

Voice-based assessments of trustworthiness, competence, and warmth in blind and sighted adults

The study of voice perception in congenitally blind individuals allows researchers rare insight into how a lifetime of visual deprivation affects the development of voice perception. Previous studies have suggested that blind adults outperform their sighted counterparts in low-level auditory tasks testing spatial localization and pitch discrimination, as well as in verbal speech...

Developmental Changes in Adolescents' Olfactory Performance and Significance of Olfaction

Aim of the current work was to examine developmental changes in adolescents’ olfactory performance and personal significance of olfaction. In the first study olfactory identification abilities of 76 participants (31 males and 45 females aged between 10 and 18 years; M = 13.8, SD = 2.3) was evaluated with the Sniffin Stick identification test, presented in a cued and in an uncued...
