Inhibition of return spreads across 3-D space.

چکیده
Focusing attention to a location in 3-D space operates much the same as in 2-D space. Attending a location in 2-D space is followed by a selective inhibitory aftereffect known as inhibition of return (IOR). Here, we report the results of two 3-D reflexive cuing studies in which depth was defined by binocular disparity. As has been shown before, attentional cuing was specific for x-y-z locations. However, the present results show that IOR is not depth specific. After a specific location in x-y-z is cued, IOR occurs for the depth plane in front of and behind the cued location. The finding that IOR spreads across depth planes may be related to how inhibited locations are encoded in the superior colliculus. We argue that the functional role of a depth-blind IOR is to bias attention against going back to any part of a previously attended object.

Objects do not aid inhibition of return in crossing the vertical meridian.
Location-based cuing experiments have shown that inhibition of return (IOR) spreads beyond a cued location but appears to be confined to the cued hemifield by the vertical meridian. Previous studies have also shown that IOR can spread across objects and here we investigate whether an object can be used to mediate the spreading of IOR into the opposite hemifield. Two experiments used a rectangul...
متن کاملChristian Norberg-Schulz and the Existential Space
The historian-theoretician Christian Norberg-Schulz, examining the development of his ideas across 30 years. While Norberg-Schulz started out with Intentions in Architecture (1963), a work that was clearly influenced by structuralist studies, he soon shifted to a phenomenological approach with Existence, Space and Architecture (1971), and then with Genius Loci (1980) and The Concept of Dwelling...
متن کاملParallelisms of PG ( 3 , 4 ) with automorphisms of order 3 Svetlana
A spread is a set of lines of PG(d, q), which partition the point set. A parallelism is a partition of the set of lines by spreads. Some constructions of constant dimension codes that contain lifted MRD codes are based on parallelisms of projective spaces. It is known that there are 3 types of spreads in PG(3, 4) regular, subregular and aregular. A parallelism is regular if all its spreads are ...
متن کاملSolving Fully Fuzzy Dual Matrix System With Optimization Problem
In this paper, the fuzzy dual matrix system as AX + B = CX + D in which A, B, C, D, X are LR fuzzy matrices is studied. At first we solve 1-cut system in order to find the core of LR fuzzy solution; then to obtain the spreads of the LR fuzzy solution, we discuss in several cases. The spreads are obtained by using multiplication, quasi norm and minimization problem with a special objective funct...
متن کاملUnderstanding the Role of VIX in Explaining Movements in Credit Spreads
Why does the VIX and market return explain changes in credit spreads? Existing literature suggests these factors proxy for macroeconomic risk. In this paper, we investigate an alternative hypothesis that the VIX in its role as a fear index impacts intermediary and arbitrageur capital, impacting spreads and resulting in decreased market integration across credit and equity markets. We document t...
