More than five decades ago it was postulated that sensory neurons detect and selectively enhance behaviourally relevant features of natural signals. Although we now know that sensory neurons are tuned to efficiently encode natural stimuli, until now it was not clear what statistical features of the stimuli they encode and how. Here we reverse-engineer the neural code of Drosophila photoreceptor...

The authors examined the congruency hypothesis that health messages framed to be concordant with dispositional motivations will be most effective in promoting health behaviors. Undergraduate students (N=63) completed a measure of approach/avoidance orientation (behavioral activation/inhibition system) and read a gain- or loss-framed message promoting flossing. Results support the congruency hyp...

The aim of this paper is to provide a review of eye movements during action execution, action observation, and movement imagery. Furthermore, the paper highlights aspects of congruency in gaze metrics between these states. The implications of the imagery, observation, and action gaze congruency are discussed in terms of motor learning and rehabilitation. Future research directions are outlined ...

We show how optical flow estimates can be combined with boundary estimation to improve estimates of motion. The improvement is associated with blending of estimates from complementary bases of operation. The paper combines a phase-based method for optical flow with a time extended version of the phase congruency operator. By evaluation on synthetic and real image sequences, the combination of t...

In this paper, we present a method for edge segmentation of satellite images based on 2-D Phase Congruency (PC) model. The proposed approach is composed by two steps: The contextual non linear smoothing algorithm (CNLS) is used to smooth the input images. Then, the 2D stretched Gabor filter (S-G filter) based on proposed angular variation is developed in order to avoid the multiple responses in...

Previous research on the subject of vividness effects in persuasion has yielded conflicting outcomes that are difficult to interpret. The authors outline a theoretical position that anticipates conditions under which vivid message presentations can either enhance or inhibit message processing and persuasion. The key moderator is vividness congruency, which is defined as the extent to which the ...
