Pulling the other one: 1st- and 2nd-order visual information interact to determine perceived location
We demonstrate that the 1st- and 2nd-order characteristics of a visual stimulus can have a profound influence on each other in terms of perceived position. We use the parameter of spatial separation to selectively manipulate the effect of one characteristic upon the other. 1st-order features have their largest effect upon the perceived position of 2nd-order structure when separation is small, w...
متن کاملImproved model-order reduction by using spacial information in moments
The new concept of multinode moment matching (MMM) is introduced in this paper. The MMM technique simultaneously matches the moments at several nodes of a circuit using explicit moment matching around = 0. As compared to the well known single-point moment matching (SMM) techniques (such as asymptotic waveform evaluation), MMM has several advantages. First, the number of moments required by MMM ...
متن کاملFrom 1st Order Embodiment to 2nd Order Embodiment: toward a Cognitive Walker
Studies of control structures underlying insect motor control, in particular walking and climbing, has led to solutions that fit the embodiment approach. The latter has been characterized by R. Brooks as allowing for "intelligence without representation" [I]. Walknet, a system formed by artificial neurones, has proven able to describe quite different aspects of walking and climbing as observed ...
متن کامل1st- and 2nd-order motion and texture resolution in central and peripheral vision
STIMULI. The 1st-order stimuli are moving sine gratings. The 2nd-order stimuli are fields of static visual texture, whose contrasts are modulated by moving sine gratings. Neither the spatial slant (orientation) nor the direction of motion of these 2nd-order (microbalanced) stimuli can be detected by a Fourier analysis; they are invisible to Reichardt and motion-energy detectors. METHOD. For the...
متن کاملOn the decline of 1st and 2nd order sensitivity with eccentricity.
We studied the relationship between the decline in sensitivity that occurs with eccentricity for stimuli of different spatial scale defined by either luminance (LM) or contrast (CM) modulation. We show that the detectability of CM stimuli declines with eccentricity in a spatial frequency-dependent manner, and that the rate of sensitivity decline for CM stimuli is roughly that expected from thei...
