Sensory Measurements: Coordination and Standardization [PDF]
Do sensory measurements deserve the label of “measurement”? We argue that they do. They fit with an epistemological view of measurement held in current philosophy of science, and they face the same kinds of epistemological challenges as physical ...

Complementarity in Psychophysics [PDF]
Besides the application of the notion of complementarity to psychological and physical descriptions of the individual, this paper explores the possibility of defining complementary observables in the same phenomenal domain. Complementary emotional observables are defined from experimental data on experienced emotions reported by subjects who have been ...

Intact and deficient contextual processing in schizophrenia patients
Schizophrenia patients are known to have deficits in contextual vision. However, results are often very mixed. In some paradigms, patients do not take the context into account and, hence, perform more veridically than healthy controls. In other paradigms,

When are abrupt onsets found efficiently in complex visual search? : evidence from multi-element asynchronous dynamic search [PDF]
Previous work has found that search principles derived from simple visual search tasks do not necessarily apply to more complex search tasks. Using a Multielement Asynchronous Dynamic (MAD) visual search task, in which high numbers of stimuli could ...

ABSTRACT Background According to the National Health and Nutrition Examination Survey (NHANES), more than 20 million Americans suffer from chronic taste problems. Unfortunately, quantitative testing is rarely performed, self‐reports are inaccurate, and “taste” is often confused with olfaction‐dependent flavors.

Risk prediction error signaling: A two-component response?
Organisms use rewards to navigate and adapt to (uncertain) environments. Error-based learning about rewards is supported by the dopaminergic system, which is thought to signal reward prediction errors to make adjustments to past predictions.

PSYCHOPHYSICS OF REMEMBERING [PDF]
We present a new model of remembering in the context of conditional discrimination. For procedures such as delayed matching to sample, the effect of the sample stimuli at the time of remembering is represented by a pair of Thurstonian (normal) distributions of effective stimulus values.

ABSTRACT Background Olfactory dysfunction affects up to 22% of the population. Accurate assessment is vital for diagnosis and tracking outcomes, often using patient‐reported outcome measures (PROMs). Aims We aimed to develop and validate a novel questionnaire for assessing olfactory and gustatory dysfunction.

Low‐contrast visual acuity versus low‐luminance visual acuity in choroideremia
Clinical relevance Choroideremia is a progressive X‐linked inherited rod‐cone dystrophy. Patients present with nyctalopia and progressive visual field loss, but visual acuity remains well preserved early on. This study showed that low‐luminance visual acuity may be a useful clinical outcome measure during earlier disease stages.

How Does Our Visual System Achieve Shift and Size Invariance? [PDF]
The question of shift and size invariance in the primate visual system is discussed. After a short review of the relevant neurobiology and psychophysics, a more detailed analysis of computational models is given.
