on a computer screen. They respond to real- Significant economic savings and productivity world situations and make decisions. Based on gains in worker performance are estimated even their actions, computer calculated and scored measurement profiles are generated for 25 environmental quality (Fisk, 2000). Real-world validated characteristics of human functioning.
22 adults between the ages of 18 and 35 years conditions that are volatile, complex, and participated in a randomized within subjects study design. The decision-making abilities of feedback. Therefore, the measurement tool the study participants were assessed under three needs to capture functioning as it happens in the different and well characterized conditions - designed to measure the process of thinking and continuously during all the conditions. All other has been widely used in many industries to conditions including the ventilation rate were assess cognitive and behavioral responses to real-world task situations (Satish and Streufert,1997).

Overall concurrent at a greater level) from treatment level 2 to 3, no and predictive validity coefficients consistently differences among treatment were obtained for exceed r=+.60. Reliability values range from comparisons of treatment levels 1 and 2 for r=+0.7 to r=+0.94 (Streufert et al., 1988). The initiative, but treatment level 3 differed methodology has been used to study the effects significantly from the other two treatments. The of beta-blockers, alcohol, caffeine, marijuana, tranquilizers (Streufert, et al., 1993; Streufert, et activity. While again no differences were al., 1997; Satish and Streufert, 2003). The SMS tool is highly sensitive to small differences in drug or environmental influences upon human conditions 3 exceeded performance during the functioning with real-world relevance (Streufert, other two treatments. No differences among any et al., 1996; Streufert and Satish, 2005).
