Initially, the participants undergo all pre-test assessments at the Neuropsychology Assessment Center prior to being deemed eligible for the experiment. Next, participants will be scheduled individually to visit the Race Lab to become acquainted with the lab and virtual environment. Basics of the research study will be explained to each participant as part of the adaptation process. This will include a brief educational lesson on the Psychological Skills Training intervention. Following the adaptation period, the participant will commence with the experimental race-car psychoeducational intervention.
Design. A single-case approach with the Range-Bound Changing Criterion design (RBCC) will used. The RBCC design is a variant of the changing criterion design used in single-subjects research to allow for the systematic shaping of behaviors in the pursuit of short- and long-term based objectives. As a result, the design adequately allows for the application of the Learning-Modification-Application Model (LMA), which is based on the premise of periodization (i.e., step-wise incremental changes as a means to improve performance through increased challenges). That is, following baseline collection, a performance range-bound criterion will be established a-priori based on the phase of the LMA model. Control is established when the participant's performance consistently matches or surpasses the criterion within the given phase of the LMA and continues to progress throughout the subsequent intervention phases as performance criteria becomes more rigorous. See Table 1 and Figure 1 for the basics of the RBCC Design.

Procedural Steps. There are three main phases of the experiment- Learning, Modification and Application. Within the Learning and Modification phases, participants will be required to complete five separate time-trials (i.e., race against the clock in the absence of other competitors), with each trial consisting of four laps. Multiple checkpoints within the race along with the finish line will allow performance times to be collected. The Application phase will also include five separate time trials, but the race will include competitors.
Throughout the experiment, the participant will be connected to physiological recording devices and data will be collected via the baseline and in-trial activities, which include heart rhythms (Beats per minute (BPM) and Heart Rate Variability - (HRV)), Electromyograph (EMG), respiration, and subjective perceptions of affect. Following each experimental phase, immersion, cognitive and somatic anxiety measures will be taken along with self-efficacy. Objective and subjective data from the trials will be reduced and Individual Zone of Optimal Functioning (IZOFs) will be determined to be utilized in the Psychological Skills Training aspect of the experiment.
Psychological Skills Training (PST). The primary focus of PST is to assist the participants in acquiring adequate self-regulatory and coping skills as a mean to increase the participants' coping repertoire.
