Contrasting contrastive-topicalization strategies
Anuario del Seminario de Filología Vasca "Julio de Urquijo", 2023 This paper offers a comparison and preliminary analysis of ‘topicalization’ strategies in German, Basque, and English. I argue that Basque and English topics at the left periphery are dislocated elements resumed by pronominal correlates, a configuration more directly evidenced in German.

The functional role of contrast adaptation [PDF]
, 1988 Prolonged inspection of high contrast sinewave gratings increases the contrast required to detect gratings having a similar spatial frequency and orientation. The functional role of such adaptation has, however, in the past, eluded disclosure.

Vision Research, 1998 Perceived contrast, contrast detection thresholds and contrast discrimination thresholds were measured in the presence and absence of surrounding patterns of a similar spatio-temporal makeup. In the foveal retina we found that the perceived contrast of the central pattern was reduced by the presence of the contrast surrounds with the effect being ...
