Inhibition control is one of the executive functions identified as the process by which goals influence prepotent response tendency. Most of the engineering courses include problem solving activities, and it has been proven that cognitive inhibition abilities improve students’ performance. So, understanding the factors that can enhance interference control skills is highly valuable in education. The Stroop task was designed to investigate interference control by evaluating how incongruent conditions can increase response time (RT), called the Stroop effect. In this study, we investigate the impact of indoor temperature (20° C, 24.40° C, and 26° C) on interference control ability using Event-Related Potential (ERP) studies. Ten engineering students from the University of Oklahoma performed Stroop/reverse Stroop tasks using Neurobs’ Presentation (Neurobehavioral Systems, Inc., Albany, CA). The ERP components related to the Stroop effect and the anatomical location of the topographic scalp maps were evaluated. The prefrontal network is active during the process, with one exception. N100-N200 components with higher amplitudes are related to the selective attention observed in this study in all three thermal conditions. The statistical analysis showed a significant impact of the thermal condition on response time in the incongruent condition presented by the Stroop test and general incongruent condition.
