In the present study, we tested the hypothesis that brain activation would reflect perceptual choices. To probe this question, we used functional magnetic resonance imaging (fMRI) during a challenging fear-disgust, two-choice discrimination task. We investigated how moment-to-moment fluctuations in fMRI signals were correlated with perceptual choice by computing a choice probability index that ...

This article deconstructs the conventional theory that "brightness" and "lightness" constitute perceptual dimensions corresponding to the physical dimensions of luminance and reflectance, and builds in its place the theory that brightness and lightness correspond to computationally defined "modes," rather than dimensions, of perception. According to the theory, called gamut relativity, "blackne...

grid computing is a term referring to the combination of computer resources from multiple administrative domains to reach a common computational platform. mobile computing is a generic word that introduces using of movable, handheld devices with wireless communication, for processing data. mobile computing focused on providing access to data, information, services and communications anywhere an...

In the upcoming 6G era, network communication will no longer be focused solely on indicators, such as bandwidth and latency. The influx of distributed service nodes gradually perfected deep learning theories are now pushing environment into a wave intelligence. more emphasis placed immersive experience humans in space where perception, transmission, computing integrated. Consequently, this prom...

The perceptual error of the investors is one of the issues discussed in behavioral finance. The perceptual error is a wrong sensual or perceptual error.  That is, what we see or hear does not match with the reality. Regarding the fact that the perception of individuals is affected by their worldview and beliefs and religious attitudes can also affect their viewpoint, in this study, the relation...

this article addresses the perceptual correlates of compensatory lengthening in persian. in a perception experiment, duration, spectral tilt measurements h1-h2 and h1-f1 and f0 were varied in several steps based on the results from a production experiment (sadeghi, 2007). subjects were asked to identify the tokens involving vowel length. results revealed that duration is the most reliable perce...

The current research sets out to identify and scrutinize the impact of the CEO’s perceptual biases in judgment and economic decision-making on the reporting quality of the firms listed on the Tehran Stock Exchange. Adopting a mixed method, the present study first seeks to detect the components and indices of CEO’s perceptual biases via critical appraisal and with the special participation of 10...

Expectations about future motions can influence both perceptual judgements and pursuit eye movements. However, it is not known whether these two effects are due to shared processing, or to separate mechanisms with similar properties. We have addressed this question by providing subjects with prior information about the likely direction of motion in an upcoming random-dot motion display and meas...
