Two connectionist models are reported that simulated the defining features of the double dissociation between phonological and surface dyslexia in word reading. One model was a feed-forward, three-layer perceptron, and the other included recurrent connections. Neither model contained an architectural separation of sublexical and lexical processes, nor of phonological and semantic processes. Ana...

Two connectionist models are reported that mimicked the defining features of the double dissociation between phonological and surface dyslexia in word reading. One model was a feed-forward, three-layer perceptron, and the other included recurrent connections. Neither model contained an architectural separation of sublexical and lexical processes, nor of phonological and semantic processes. Anal...

Patients with hemispatial neglect restricted to near (within reaching distance) or to far space (beyond reaching distance) have been described. This constitutes a double-dissociation considered by current neurocognitive thinking as compelling evidence for separate networks. However, a similar double-dissociation exists with respect to perceived as opposed to imagined space. If the organization ...

Measurements at the lhc have shown that there are sizable disagreements among Monte Carlo (mc) implementations of “soft” processes based on cross sections proposed by various physics models, and that it is not possible to reliably predict all such processes, or even all aspects of a given process, using a single model [1, 2, 3]. In the cdf studies of diffraction at the Tevatron, all processes a...

Diffractive scattering in the presence of a large momentum transfer is an ideal place to study the short distance rapidity gap producing mechanism. Previous studies (experimental and theoretical) in this area have focussed on gaps between jets and on high-t vector meson production. We propose the measurement of double dissociation at high-t. We examine the numerous advantages to studying this m...

Proper name anomia and proper name sparing are unusual disorders characterized by a selective inability, or sparing, to retrieve proper names as opposed to common names. They may eventually demonstrate that these two categories of names are independently processed in the brain at the semantic or lexical/orthographic level. Yet, differences in patient assessment make comparison between cases dif...
