Simple Mediation Model with Useful Field of View Test (UFOV) Total Score as Mediator. The simple mediation model of X→M→Y (where X is training condition, M is UFOV total score at post-test, and Y is TIADL at post-test). The bootstrapping method with bias-corrected confidence estimates (based on 5,000 bootstrap samples) was used to test the mediation hypothesis (Preacher & Hayes, 2004). The indirect effect of the mediator (ab) is presented in text and was calculated by multiplying a × b paths. An asterisk indicates that the bootstrap estimate is significant at the 0.05 alpha level.
