Synthetic Aperture Personality Assessment

Synthetic Aperture Personality Assessment (SAPA) is a method used for telemetric assessment of individual differences, primarily in the context of online surveys. The SAPA method uses data collected from the administration of large inventories of personality assessment items to large pools of participants, though it differs from traditional data collection methods in that each participant responds to only a small subset of all available items.
