Environmental stressor: Environmental stressor means any force or event in the human or natural environment that may cause a person to experience stress. Some examples of environmental stressors include: noise, air pollution, crowding, traffic congestion, terrorism, natural disasters and extremes of temperature. Different environmental stressors on people can impact people's behaviour, mood, cognitive function, physical health and/or psychological well-being.
- Noise: Noise is an unwanted sound. Chatter in the meetings, sounds from the hallway, scraping sounds from chairs and tables, sounds from adjacent rooms, ventilation, sounds and traffic noise.
- Crowding: Stress associated with crowding is not due just to density of people or numbers of people in a space. Whether an environment seems crowded and elicits a stress response dependson the social setting, the physical setting, the goals of each individual in the space and whether thegoals conflict, perceived threats to personal control, level of intimacy of people occupying aspace, personal characteristics of each individual in the space and the coping assets of eachindividual in the space.
- Temperature: Extremes changes of temperature either too hot or too cold put physical demands on the body. Extremes of temperature can impact performance level. Temperature increases aggression increases.
- Evidence of effectiveness: Studies have found that there is a correlation between environmental stressors and academic performance. These studies have also showed a correlation between learning and environmental stressors.
- Critics and their rationale: Overemphasis on achievement as an outcome which ignores the impact the environment has on behavior and the effects of individual differences.
