Within the SOBC Measures Repository, researchers have access to measures of mechanistic targets that have been (or are in the processing of being) validated by SOBC Research Network Members and other experts in the field.

The experimental medicine approach involves: identifying an intervention target, developing measures to permit verification of the target, engaging the target through experimentation or intervention, and testing the degree to which target engagement produces the desired behavior change. The SOBC program aims to implement a mechanisms-focused, experimental medicine approach to behavior change research and to develop the tools required to implement such an approach. By integrating work across disciplines, this effort will lead to an improved understanding of the underlying principles of behavior change. 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. The Spatial Span Task is a behavioral measure of working memory capacity, the cognitive ability to store and manage information on a transient basis.
