An Electrophysiological Index of Perceptual Goodness
A traditional line of work starting with the Gestalt school has shown that patterns vary in strength and salience; a difference in "Perceptual goodness." The Holographic weight of evidence model quantifies goodness of visual regularities. The key formula states that W = E/N, where E is number of holographic identities in a pattern and N is number of elements. We tested whether W predicts the am...
متن کاملAn electrophysiological index of stimulus unfamiliarity.
This study investigated the functional significance of the N2 response to novel stimuli. In one condition, background, target, and deviant stimuli were simple geometric figures. In a second condition, all stimulus types were unfamiliar/unusual figures. In a third condition, background and target stimuli were unusual figures and deviant stimuli were simple shapes. Unusual figures, whether they w...
متن کاملContext influences early perceptual analysis of faces--an electrophysiological study.
Electrophysiological and hemodynamic correlates of processing isolated faces have been investigated extensively over the last decade. A question not addressed thus far is whether the visual scene, which normally surrounds a face or a facial expression, has an influence on how the face is processed. Here we investigated this issue by presenting faces in natural contexts and measuring whether the...
متن کاملA global Goodness–of–Fit index for PLS structural equation
Riassunto: Scopo di questo lavoro è proporre un indice globale di bontà dell’adattamento per i modelli ad equazioni strutturali stimati mediante il metodo PLS. Al momento gli indici comunemente utilizzati in questo ambito sono la comunalità (bontà di adattamento del modello esterno) e la ridondanaza (qualità del modello interno). Si propone un indice che, alla stregua del test del chi-quadro e ...
متن کاملElectrophysiological correlates of figure–ground segregation directly reflect perceptual saliency
In a figure identification task, we investigated the influence of different visual cue configurations (spatial frequency, orientation or a combination of both) on the human EEG. Combining psychophysics with ERP and time-frequency analysis, we show that the neural response at about 200ms reflects perceptual saliency rather than physical cue contrast. Increasing saliency caused (i) a negative shi...
