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)
Many observers perceive depth when a configuration of nonconcentric circles is rotated on a disc. While it has been suggested by a number of investigators that motion parallax has a role in generating this phenomenon, the supporting data are equivocal. The current study proposed that the ambiguity regarding the role of motion parallax may have arisen… (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)
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.
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)
Rapid, successive presentations of an eccentric circle pattern and its mirror-image elicited apparent depth and, as has been previously demonstrated for the Benussi effect, there was an increase in apparent depth with an increase in circle eccentricity. Taken together, these data were interpreted as contravening Wallach, Adams, and Weisz's account of the… (More)
