Context Effects in Strategic Environments: An Experimental Study

Context effects have traditionally been explored as a reliability concern and detected through the use of univariate, test/retest techniques. We argue that context effects may actually represent a threat to validity and, as a consequence, traditional univariate measurement techniques will fail to detect their full impact. Using an experimental design which manipulates the context of questions involving ethics, we demonstrate that priming influences the relationship of variables to each other and has an effect on the dimensional reduction of the responses for the two experimental groups. We conclude that the problem posed by context effects is not just one of reliability, but also one of validity. Implications for future basic research on attitude formation are drawn.

Illumination Mode

The tilted beam illumination method is used to improve the resolution comparing with the axial illumination mode. Using this advantage, a restoration method of several tilted beam images covering the full azimuthal range was proposed by Saxton, and experimentally examined. To make this technique more reliable it seems that some practical problems still remain. In this report the restoration was attempted and the problems were considered. In our study, four problems were pointed out for the experiment of the restoration. (1) Accurate beam tilt adjustment to fit the incident beam to the coma-free axis for the symmetrical beam tilting over the full azimuthal range. (2) Accurate measurements of the optical parameters which are necessary to design the restoration filter. Even if the spherical aberration coefficient Cs is known with accuracy and the axial astigmatism is sufficiently compensated, at least the defocus value must be measured. (3) Accurate alignment of the tilt-azimuth series images.
