Rapid, apparent, to-and-fro (right-left) rotation of the Necker cube sharply reduced reversals in depth for 10 undergraduates. This finding was considered consistent with the satiation theory of Necker cube reversals.
The magnitude of the Ebbinghaus illusion has been reported to be greater when test element and context elements are figurally similar as opposed to figurally dissimilar. In the current investigation with 16 observers, illusion magnitude was greater for a figurally similar configuration even though the context elements of the figurally similar configuration… (More)
NATO is seeing something of a rebirth manifested by the Wales summit in September 2014. The summit did not fix all NATO's woes, but it did address a number of them, especially the reconfigured security situation in Europe. However, it remains unclear how NATO can add to its already full plate, especially during a time of personnel cuts and zero-growth… (More)
CENTER for STRATEGIC LEADERSHIP and DEVELOPMENT The United States Army War College educates and develops leaders for service at the strategic level while advancing knowledge in the global application of Landpower. The purpose of the United States Army War College is to produce graduates who are skilled critical thinkers and complex problem solvers.… (More)
Dramatic political, economic, and social changes across both the Greater Middle East and Latin Ameri-ca over the last several years—in some instances revolutionary , in others evolutionary—have had profound implications for global security generally, and U.S. security specifically. In the Middle East, although initial causal factors may have been the same… (More)
It was hypothesized that the apparent depth of the Benussi effect could be elicited using stimuli corresponding to retinally disparate images. When such stimuli were presented rapidly and successively in a manner approximating apparent motion, 21 of 22 observers reported apparent depth.
The perceived depth of the Benussi effect is usually demonstrated by presenting a configuration of nonconcentric circles on a rotating disc. However, in the current investigation with 21 undergraduates the Benussi effect was elicited by presenting an eccentric configuration of rectangles. Depth was reported when the configuration of eccentric rectangles was… (More)
A circle was attached to one of three lines which were changing in length and direction simultaneously. This configuration of moving lines had been found previously to induce the perception of depth. Of 26 observers 20 reported that the moving circle appeared smaller in size than a physically equal stationary circle which was located outside the changing,… (More)
Using the single staircase psychophysical method, the apparent depth threshold for the Benussi effect was determined for 5 observers. The threshold occurred at an eccentricity of 2r/3, where r equals the radius of the larger circle expressed in millimeters.
