Six experiments investigated how changes in stimulus speed influence subjective duration. Participants saw rotating or translating shapes in three conditions: constant speed, accelerating motion, and decelerating motion. The distance moved and average speed were the same in all three conditions. In temporal judgment tasks, the constant-speed objects seemed to last longer than the decelerating o...

Based on both subjective and objective data, a study was carried out in order to identify differences in the perception of thermal comfort of office workers in naturally ventilated and air-conditioned buildings. The analysis of the interviews shows that occupants of naturally ventilated office buildings are significantly more satisfied with their thermal environment than occupants in air-condit...

Sensorimotor contingency is one of the main factors to warp time perception. Voluntary actions such as saccades and hand movements affect the subjective perception of temporal duration. Although the perceived timings of action and stimulus are affected by whether an action was automatic or controlled, its effect on the subjective perception of duration has not been studied except in the case of...

Alterations in bodily awareness have been implicated in depression but there has been little detailed empirical characterisation of the degree and accuracy of body perception in the disorder. The present study examined the objective accuracy of heartbeat perception (using the Schandry mental tracking task) and the subjective degree of bodily focus (using the Bodily Consciousness Questionnaire; ...

The aim of the present study was to show that space perception depends on sensori-motor experience. We induced spatial biases by a non-conflictual lateralized sensori-motor task on twenty seven right-handed healthy volunteers (left-to-right readers). After a pre-test and before a post-test, which assessed visuo-motor and perceptual subjective midpoint in line bisection, participants performed a...

In a variety of synaesthesia, photisms result from affect-laden stimuli as emotional words, or faces of familiar people. For R, who participated in this study, the sight of a familiar person triggers a mental image of "a human silhouette filled with colour". Subjective descriptions of synaesthetic experiences induced by the visual perception of people's figures and faces show similarities with ...

As we are moving to a digital world, digital document image processing is receiving more and more attention. Digital document images are essentially binary images. In applications related to binary document images, such as data hiding and watermarking in binary images, distortion may be present and it is necessary to measure the distortion for performance comparison. However, traditional object...

The attentional blink (AB) represents a cognitive deficit in reporting the second of two targets (T2), when that second target appears 200-600 msec after the first (T1). However, it is unclear how this paradigm impacts the subjective visibility (that is, the conscious perception) of T2, and whether the temporal profile of T2 report accuracy matches the temporal profile of subjective visibility....

Subjective sensory abnormalities, such as radiating pain, dysesthesia and llodynia, are a common feature of patients presenting to a pain clinic. Objectively quantifying those abnormalities using subjective tests ( eg tuning fork, safety pin) may be difficult. There are a number of non-invasive neurodiagnostic technologies available to supplement the history and physical exam including MRI, the...

The subjective experience of discomfort in breathing, termed dyspnea (or breathlessness), is a symptom with multifactorial causes of highly complex and largely undefined psycho-physiologic mechanism(s). There are at least three discrete qualities of dyspnea likely corresponding to different types of respiratory stress and separate underlying mechanisms. Perception of dyspnea can be measured by ...
