Note. Self-confidence robustness and message credibility measured 1 to 9, resilience and self-efficacy 1 to 5, and perceived competence and task importance 1 to 7, where higher scores represented more favorable perceptions. Tension measured 0 to 4, and threat measured 1 to 7, where higher scores represented greater perceived tension/threat, and feedback acceptance 1 to 5, where higher scores indicated greater acceptance. Self-presentation concerns and concentration disruption measured 1 to 7, where higher scores represented greater concerns/disruption. Task performance measured in terms of number of targets hit, and task 2 intended length could range from 15 to 120 sec. Confederate impact ranged -3 to 3, where scores < 0 indicated a negative impact and scores > 0 indicated a positive impact.
