Localizing the spatial localization system: Helmholtz or Gibson?
Article Abstract:
Helmholtz's unconscious inference models and Gibson's general solution to ambiguity offer explanations on where the deficit in the visual localization process takes place. The former maintains that any incorrect value for retinal position or eye position would yield an incorrect calculation, while the latter states that the position of an object is determined by its relation to other things, with judgment on its location depending on the perspective adopted by the viewer when using the frame of reference.

Orienting to extinguished signals in hemispatial neglect
Article Abstract:
Research was conducted to examine the hypothesis that orienting to extinguished signals in hemispatial neglect can occur without detection. Two hemispatial-neglect patients were tested using a spatial precuing paradigm for the measurement of visual attention effects. Results are in good agreement with the hypothesis that location information is registered in the neglected hemifield and that spatial orienting transpires regardless of signal detection.
