TLDR
The perceived intensity of odor under conditions of constant stimulation with hydrogen sulphide was investigated in two experiments and was found to decrease exponentially with increase of time of stimulation.Abstract:
The perceived intensity of odor under conditions of constant stimulation with hydrogen sulphide was investigated in two experiments. A two-step scaling method, involving cross-modality matching and numerical scaling of the matching continuum, was used for measuring intensity of odor. Perceptual intensity was found to decrease exponentially with increase of time of stimulation. Preliminary data concerning the subsequent recovery phase were also obtained.read more

Prevalence of olfactory impairment in older adults.

TL;DR: It is demonstrated that prevalence of olfactory impairment among older adults is high and increases with age, and self-report significantly underestimated prevalence rates obtained by olfaction testing.

A Critical Review of the Literature on Hydrogen Sulfide Toxicity
TL;DR: This review of the literature is intended as an evaluative report rather than an annotated bibliography of all the source material examined on hydrogen sulfide, noting information gaps that may require further investigation.

Odorant-specific adaptation pathways generate olfactory plasticity in C. elegans
TL;DR: Mutations in adp-1 and osm-9 do not diminish the ability of unadapted animals to respond to odorants, indicating that odorant sensation and odorant adaptation are distinct processes.

Seeing at a glance, smelling in a whiff: rapid forms of perceptual decision making.
TL;DR: It is suggested that the brain limits some types of perceptual processing to short, discrete chunks in order to facilitate the construction of global sensory images.

Psychophysical and Behavioral Characteristics of Olfactory Adaptation
TL;DR: Olfactory adaptation has been shown to be very long-lasting in some cases and may be modulated by the contribution of pre-neural events and physico-chemical properties of the odorant molecules that govern diffusion to receptor sites and post-receptor clearance.

The Psychophysics of Sensory Function.
TL;DR: In psychophysics, the challenge is to understand the mechanisms that make sensory communication possible as discussed by the authors, which is not an easy task in the sense that there is no way to measure the inner, private, subjective strength of a sensation.

Brightness and loudness as functions of stimulus duration
Joseph C. Stevens,James W Hall +1 more
TL;DR: In this article, the brightness and loudness of white light and white noise were measured by magnitude estimation for sets of stimuli that varied in intensity and duration, and the psychophysical power functions were used to generate equal loudness and equal brightness functions, which specify the combinations of intensity E and duration T that produce the same apparent magnitude.

Olfactory analogue to directional hearing.
TL;DR: The direction of a sound source can be determined binaurally by using the time difference and the loudness difference of the sound waves arriving at the two ears as mentioned in this paper, and the direction of an olf...

Duration, luminance, and the brightness exponent
TL;DR: In this paper, the relation of brightness to duration and luminance has been studied by matching one brightness to another and also by matching numbers to brightnesses (magnitude estimation), and it is shown that the shift with luminance requires the exponent of the power function for short-flash brightness to be larger than the exponent for stimuli of longer duration.
