Studies of emotional instability in smoke from fires: Decrease of thinking powers and of memory in fire smoke

The effect and degree of smoke concentration on the reduction in thinking and memory was studied. The change in memory and thinking power was estimated by the change in correction ratio for mental calculation in various smoke concentrations. The reduction of memory in a smokey environment estimated by the correction ratio for remembering the order of four color panels which were shown before smoke exposure. It is found that it is difficult to evaluate the relationship between the reduction in thinking power against smoke concentration, and relationship between the reductions of memory against smoke concentration.
