In this paper, we analyze the evolution of van Gogh’s style toward the Auvers final period using informational measures. We will try to answer the following questions: Was van Gogh exploring new ways toward changing his style? Can informational measures support the claim of critics on the evolution of his palette and composition? How "far" was van Gogh’s last period from the previous ones, can ...

Ahrrwx-The informational content of ditlercnt forecasts can be compared by regressing the actual change in a variable to be forecasted on forecasts of the change. We we the procedure in Fair and Shikr (1987) to examine the informational content of three sets of ex ante forecasts: the American Statist&i Association and National Bureau of Economic Research Survey (ASP.). Data Resources Incorporat...

Although many studies have shown that intelligibility improves when a speech signal and an interfering sound source are spatially separated in azimuth, little is known about the effect that spatial separation in distance has on the perception of competing sound sources near the head. In this experiment, head-related transfer functions (HRTFs) were used to process stimuli in order to simulate a ...

Previous research has demonstrated that people's movements can become unintentionally coordinated during interpersonal interaction. The current study sought to uncover the degree to which visual and verbal (conversation) interaction constrains and organizes the rhythmic limb movements of coactors. Two experiments were conducted in which pairs of participants completed an interpersonal puzzle ta...

Market saturation, increased competition, change in tastes and needs of customers have made Iranian companies, especially canned industries, face various challenges in relation to consumers. Under such conditions, cannery companies with the ability for proper use of available facilities and equipment such as design and development of new products, supplying high-quality and economic products an...

The conscious manipulation of mental representations is central to many creative and uniquely human abilities. How does the human brain mediate such flexible mental operations? Here, multivariate pattern analysis of functional MRI data reveals a widespread neural network that performs specific mental manipulations on the contents of visual imagery. Evolving patterns of neural activity within th...

Gibson's article, "Visually Controlled Locomotion and Visual Orientation in Animals" (1958/this issue), is the leading statement of a nonrepresentational, information-based approach to visual control. The core ideas he introduced 40 years ago resurface, explicitly or implicitly, in much contemporary work on perception and action in humans, insects, robots, and autonomous agents. The purpose of ...

Absorption spectra of visual pigments are adaptively tuned to optimize informational capacity in most visual systems. Our recent investigation of the eyes of the jumping spider reveals an apparent exception: the absorption characteristics of a visual pigment cause defocusing of the image, reducing visual acuity generally in a part of the retina. However, the amount of defocus can theoretically ...
