Many psychological therapies help clients to direct and sustain their awareness onto specific aspects of their problems to promote change. Yet, no theory-driven measure exists that can code moment-by-moment changes in awareness during a therapy session. The Depth and Duration of Awareness Coding Scheme (D-DACS) was developed using Perceptual Control Theory with this purpose and validated in an earlier study. The current research applies the D-DACS to code three publicly available therapy sessions delivered by an expert therapist and presents a visual representation of the client’s presumed attention in these sessions. The results showed the average of 61.65% of the client’s attention was focused on the D-DACS areas, which is higher than the previous studies involving novice therapists. The produced visual representation of the clients’ presumed attention helps to examine the utility of this new coding scheme and further examine the validity of the underlying theory. Such work might help in examining effectiveness of therapy in meeting the underlying theoretical foundations of change. However, limitations and areas for improvement are also evident.
