Published on September 6, 2019 by Fiona Middleton. I would say the main drawback would be the lack of ecological validity because it can be difficult to do studies on real-life aspects within a lab, along with the fact that control over variables is high within the lab. In simulation labs, a widely used evaluation environment aimed to increase ecological validity of clinical usability evaluations, researchers are able to ensure a high level of ecological validity on some dimensions (e.g., fake patients, realistic looking wards). The Problem with ecological validity is that although it is important to apply results to the real world studies with High ecological validity often lack reliability as if a study is to be like a real life situation there will be little or no control of variables, making establishing a cause and effect relationship extremely difficult. On the other hand, taking each child out of class and testing them individually, in an isolated room, will dramatically lower ecological validity. Ecological Validity: The extent to which the setting of a study can be relevant to everyday life. Although, I agree with the comment above in that it can be possible to create some settings like the Stanford Prison experiment. More specifically, ecological validity addresses whether an effect has been shown to operate in conditions that occur often for people in the population of interest. In the behavioral sciences, ecological validity refers to the judgement of whether a given study's variables and conclusions are sufficiently relevant to its population (e.g. For example, research conducted in a laboratory experiment may be considered low in ecological validity because it is not a setting humans are used to. In quantitative research, you have to consider the reliability and validity of your methods and measurements.. Validity tells you how accurately a method measures something. The extent to which research results may be generalized to other conditions, such as different settings, different treatments, different researchers, and so on. Ecological validity is one aspect of external validity in which researchers ask whether research results represent what happens in everyday life. the "real-world" context). Revised on June 19, 2020. Ecological validity is a type of external validity that refers to the extent to which the findings can be generalized to a real-life setting. The concept is that the more familiar a setting is, the lesser chance… Anxiety. Unlike traditional notions of validity, ecological validity is not necessarily related to the methodological validity of a study (i.e. The high ecological validity of these studies allows for these novel findings to be more likely generalizable to the everyday life of users. ecological validity. inferences made about the variables studied). Study notes. The four types of validity. If there are reasons to suspect the environment might influence the merit of the conclusions of the study (in terms of being able to apply them to other environments), the ecological validity may be questioned. ... Study notes Duration of Long-term Memory. Ecological Validity is a specific type of external validity.External validity refers to your ability to generalize your experimental results across populations, places, and time; ecological validity is limited to how the experimental results apply to today’s society. In the school test example, if the pupils are used to regular testing, then the ecological validity is high because the testing process is unlikely to affect behavior. So ecological validity is about assessing the validity of a study’s findings based on the environment in which the study took place.
