Abstract

This graph represents the results obtained from a mixed model analysis of a four-week acting intervention. Specifically, we found that the intervention group (who engaged in “acting” exercises and were trained by theater actors) showed more brain activation in a region attributed to reactive control. Reactive control is the ability to take actions in a “just-in-time” manner. In contrast, the control group (who attended an “Understanding the Art of Acting” theory-driven class) demonstrated lower brain activity in this region. This graph clearly illustrates group x time differences associated with the acting intervention, as well as differences at the level of the person. For instance, we find that individuals within the acting intervention group showed a lot of variation in brain activation pre and post- intervention (e.g., see differences in intercepts or “starting points” in this group and differences in slope direction). These individual differences may be attributed to person-level variables such as self-efficacy and perceived cognitive stimulation, or more structural factors such as gender. This information can be extracted from a closer examination of individuals showing differences in trends within each group. To this end, this graph facilitates the formulation of more personalized interventional approaches.
