![]() The Science of Behavior Change (SOBC) program seeks to promote basic research on the initiation, personalization and maintenance of behavior change. The dependent measure, spatial span, is the maximum number of boxes correctly recalled. The difficulty level is systematically increased by varying the number of boxes on each trial from two boxes (easiest) to nine boxes (most difficult). In the backward-span variant, at the end of each list participants attempt to recall the squares in the reverse order that they changed color. In the forward-span variant, at the end of each list participants attempt to recall the squares in the order they changed color by typing keys corresponding to each square via keypress. The task exists with two variants: forward-span and backward-span. On each trial the squares change from white to a different color in a sequence with variable orders and colors. On each trial participants are presented with an array of geometric shapes such as white squares appearing on a computer screen.
