The neural binding problem (NBP) encompasses three distinct situations: feature binding, variable binding, and the subjective unity of perception. Feature binding involves associating the correct (visual) features with objects and is fairly well understood. Variable binding arises in natural language and other abstract thought; there are ingenious proposed models, but no experimental confirmati...

People with self-attributed electromagnetic hypersensitivity (EHS) complain of subjective symptoms such as headaches, insomnia, and memory loss, and attribute these symptoms to radio frequency (...

Perceptual categorization is a key problem for an agent to cope with its internal and external world.

Peoples' subjective feelings of confidence typically correlate positively with objective measures of task performance, even when no performance feedback is provided. This relationship has seldom been investigated in the field of human time perception. Here we find a positive relationship between the precision of human timing perception and decisional confidence. We first demonstrate that subjec...

This study was designed to assess the correlation between each severity measure and patients' subjective perception or clinicians' clinical assessment. We attemp...

Sensation, decision, perception, consciousness experimental phenomenology and psychophysics are two rather different approaches to the study of perception, and rely on first-person descriptions and third-person measurements of the percept, respectively. yet, a common ground may be found in the original goal, shared by both approaches, of addressing the conscious dimension of perception. here we...
