Sep 08, 2021 · Indirect effects fascinate ecologists because they can link the population dynamics of species that do not directly interact, as in the classic example of predatory fish affecting phytoplankton abundance by consuming specific sizes of zooplankton (Brooks and Dodson 1965).

13.02.2019 · The indirect effect quantifies a mediation effect, if such an effect exists. Referring to the thirst example above, in statistical terms, the indirect effect quantifies the extent to which room temperature is associated with water drinking indirectly through thirstiness.

When a mediator is hypothesized, the total effect can be broken into two parts: the direct and indirect effect. The direct effect is the effect of exposure on ...

Indirect Effects Theory and Model. By definition, the indirect effects theory is the assessment of the “impact of one variable on another as that variable’s influence works through one or more intervening variables” (Holbert, 2003).

The indirect effects theory examines that relationship. It’s important to understand this theory because it is how society thinks and works.
