In aviation safety incident reports, lack of situation awareness (SA) is often attributed as the cause of negative safety outcomes, such as accidents. While the predominant model of SA has identified three components of SA, perception, comprehension, and projection, assumptions of their relationships with each other and external criteria are yet tested empirically. Specifically, SA theory suggests comprehension SA fully mediates the relationship between perception and projection SA. Additionally, research on the relationships between individual differences and SA is lacking. The purpose of the current study is to test a comprehensive model of SA which simultaneously examines the described mediation, relationships with individual differences antecedents of SA, and its utility as a predictor of safety using structural equation modeling (SEM). A sample of 349 employees from a diverse background of occupational areas were recruited via Amazon Mechanical Turk to test the model. While self-report measurement of SA was an excellent predictor of safety, the current study did not find empirical support for the presumed mediation among the SA components, and found the relationships between individual differences and SA which contradict extant SA theory. The results suggest differentiating between typical versus maximal SA. Implications for theory and practice are discussed.

The collaborative efforts of families, educators, and policy makers have merged vocational training with special education services for students with disabilities. The Individuals with Disabilities Education Act of 2004 introduced mandates for schools to provide transition services for students with disabilities based on three areas of need: a) education, b) employment, and independent living. This legislation has led to more work-based learning programs that meet the postsecondary needs for students with disabilities. Despite this increase in work-based learning programs many students with disabilities are still unable to make successful transitions into postsecondary outcomes. Using a mixed method design, this study examined the impact of a Job Experience Training (JET) program on the executive functioning skills of seven young men (15 to 18 years of age) over the course of seven weeks at an assisted living facility. Results of the teacher evaluations showed the students were capable of completing tasks, making individual goals, and increasing executive functioning skills while participating in the JET program. Conversely, the results from the parent and student assessments showed little to no change in executive functioning skills once the participants were outside the context of the assisted living facility. Future research is encouraged to examine a longitudinal study across multiple job sites that evaluates and measures the students’ ability to transfer executive functioning skills to other contexts and further investigate mentoring as the core teaching strategy of a JET program.
