Once a measure has gone through these three stages, it will then either be Validated or Not validated according to SOBC Research Network standards. Evidence relating to each stage includes at least one peer-reviewed publication or original data presentation (if no peer-reviewed research is available to support the claim) and is evaluated by SOBC Research Network Members and experts in the field. The third stage of validation requires demonstration that the measure can be Influenced there must be evidence that the measured target is malleable and responsive to manipulation. For example, if the proposed measure is a questionnaire, the score on the measure should indicate the activity of the target process, and it must have strong psychometric properties. The second stage of validation requires demonstration that the level and change in level of the chosen mechanistic target can be Measured with the proposed measure (assay). This evidence may include references for the proposed measure, or theoretical support for the construct that the proposed measure is intended to assess. The first stage of validation requires a measure to be Identified within the field there must be theoretical support for the specific measure of the proposed mechanistic target or potential mechanism of behavior change. The SOBC Validation Process includes three important stages of evaluation for each proposed measure: Identification, Measurement, and Influence. 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.
#Backward digit span subtest verification#
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.
#Backward digit span subtest trial#
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.
