Finding F-0421

“At 2,500 ppm, large and statistically significant reductions occurred in seven scales of decision-making performance (raw score ratios, 0.06–0.56), but performance on the focused activity scale increased.”

Structure

Factor: Carbon dioxide (CO₂)
Outcome: Cognitive performance
Population: adult volunteers
Setting: exposure chamber (office-like), US
Study design: blinded controlled exposure study with balanced crossover order: 22 participants in six groups exposed in an office-like chamber to CO2 at 600, 1,000 and 2,500 ppm in three 2.5-hour sessions on one day, ventilation rate and temperature constant, computer-based Strategic Management Simulation test of decision-making performance analysed with analysis of variance (class 3)
Sample: 22 participants
Caveat: decision-making performance filed under cognitive-performance; the focused activity scale moved in the opposite direction
