Ecological validity can be considered a commentary on the relative strength of a study's implication (s) for policy, society, culture, etc. This term was originally coined by Egon Brunswik [ 1 ] and held a specific meaning. He regarded ecological validity as the utility of a perceptual cue to predict a property (basically how informative the ...
The total of interacting organisms (biocoenosis) and non-living things (biotope) in a specific environment. A branch of ecology which studies how flows of energy and matter interact with biotic elements of ecosystems. The use of mathematics, computer programs and models to understand and predict ecosystem behavior.
External validity is the validity of applying the conclusions of a scientific study outside the context of that study. [ 1 ] In other words, it is the extent to which the results of a study can generalize or transport to other situations, people, stimuli, and times. [ 2 ][ 3 ] Generalizability refers to the applicability of a predefined sample ...
v. t. e. The bioecological model of development is the mature and final revision of Urie Bronfenbrenner's ecological system theory. The primary focus of ecological systems theory is on the systemic examination of contextual variability in development processes. It focuses on the world outside the developing person and how they were affected by it.
The balance of nature, also known as ecological balance, is a theory that proposes that ecological systems are usually in a stable equilibrium or homeostasis, which is to say that a small change (the size of a particular population, for example) will be corrected by some negative feedback that will bring the parameter back to its original "point of balance" with the rest of the system.
Ecological psychology is primarily concerned with the interconnectedness of perception, action and dynamical systems. A key principle in this field is the rejection of the traditional separation between perception and action, emphasizing instead that they are inseparable and interdependent. In this context, perceptions are shaped by an ...
Ecological study. In epidemiology, ecological studies are used to understand the relationship between outcome and exposure at a population level, where 'population' represents a group of individuals with a shared characteristic such as geography, ethnicity, socio-economic status of employment. [1] What differentiates ecological studies from ...
Competition (biology) Competition is an interaction between organisms or species in which both require a resource that is in limited supply (such as food, water, or territory). [ 1 ] Competition lowers the fitness of both organisms involved since the presence of one of the organisms always reduces the amount of the resource available to the other.
