The reaction time of subject groups in rest conditions due to the activity room’s microclimate: A laboratory tests

Abstract

This study aims to measure the effect of perceived thermal sensation and comfort to the reaction time for participants aged 18-22 years (Group A) and 35-45 years (Group B). Data collection was done by measuring the reaction time ability and respondent’s subjective response to the air conditions (AC) setting of 18°C (AC-18), 24°C (AC-24), and Non AC (Control). Results show that in the 18°C AC setting the reaction time of Group A with regular stimulus was slower than Group B. Whereas by giving random stimulus, the reaction time of Group B was slower compared to Group A. In the condition of the room with AC 24°C and AC settings not used (T = 26.19 ± 0.55°C), ordered and random stimulus reaction time of Group B slower than Group A. Furthermore, there is a somewhat different trend between subjective sensation felt by Group A and Group B. The reduced sensitivity of taste senses on the skin part is likely to cause respondents in Group B to feel COLD slower than Group A. Likewise in the thermal comfort trend, where Group A looks more sensitive to changes in existing air conditioning settings. In general, this study shows the importance of including age factors in the design of intelligent AC controlling systems that are more environmentally friendly.
