Development of the Spatial Judgment Experimental Task

Abstract

Moore builds on the work of Conner (Technical Report #11) to develop an entirely new experimental task. This task, with the important restriction that stimuli are presented in a particular order, does successfully meet the criterion of independent trials. Each stimulus of the task developed here resembles a checkerboard with 100 rectangles. The task can be either ambiguous (it has no correct answer and it is perceived as having no correct answer) or veridical (it has a correct answer and respondents normally are able to distinguish it). A later version, now usually called Contrast Sensitivity, uses pairs of the patterns that Moore developed here. As with Technical Report #11, this Technical Report discusses questions of how to attain criteria for the task, and how to assess success. The document labelled Technical Report #15 was retrieved from Moore’s dissertation.
