Development of the spatial judgement experimental task. [TR 15]

There are two versions of this report (one of actual report, one as appendix to Moore's dissertation). Appendix copy is a higher quality scan.

Moore builds on the work of Conner (TR#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 TR#11, this TR discusses interesting questions of how to attain criteria for the task, and how to assess success. The document labelled TR#15 was retrieved from Moore’s dissertation, which, according to Moore, is identical to the TR.
