The ability to recognize the same image projected to different retinal locations is critical for visual object recognition in naturalist contexts. On many theories translation invariance for objects only extends to trained retinal locations. On this approach, a familiar object projected to a non-trained location should not be identified. On another approach invariance is achieved “on-line”, suc...

Effects of the contrast of target luminance and background luminance, and of the absolute level of target luminance, on representational momentum for the remembered final location of a previously viewed moving target were examined. Targets were high in contrast or luminance, decreasing in contrast or luminance, increasing in contrast or luminance, or low in contrast or luminance; the background...

Classic theories of cognitive control conceptualized controlled processes as slow, strategic, and willful, with automatic processes being fast and effortless. The context-specific proportion compatibility (CSPC) effect, the reduction in the compatibility effect in a context (e.g., location) associated with a high relative to low likelihood of conflict, challenged classic theories by demonstrati...

Theories of object representation can be classiied as structural, holistic or hybrid, depending on their approach to the mereology and compositionality of shapes. We tested the predictions of some of the current theories in three experiments, by quantifying the eeects of various priming cues on response times to 3D objects. In experiment 1, there were two possible locations for the stimulus com...

We apply a recently proposed mechanism for predicting the weak mixing angle to theories with TeV-size dimensions. “Reconstruction” of the associated moose (or quiver) leads to theories which unify the electroweak forces into a five dimensional SU(3) symmetry. Quarks live at an orbifold fixed point where SU(3) breaks to the electroweak group. A variety of theories – all sharing the same successf...

While there is widespread agreement among vision researchers on the importance of some local aspects of visual stimuli, such as hue and intensity, there is no general consensus on a full set of basic sources of information used in perceptual tasks or how they are processed. Gestalt theories place particular value on emergent features, which are based on the higher-order relationships among elem...

A conformational analysis of the cembrene diterpenoids cembrene, cembrene A, (3Z)-cembrene A, isocembrene, casbene, and incensole, has been carried out using density functional theory at the B3LYP/6-31G* level of theory. A molecular docking analysis of these cembrenoids with tubulin has also been performed in order to assess the potential of tubulin binding of these cytotoxic agents. The macroc...
