Thus the displacement hypothesis suggests that time spent by adolescents consuming media displaces time that could be used for educational activities (Anderson and Bushman, 2001; Hofferth, 2010).
Consistent with the displacement hypothesis is the concern that media activities are sedentary activities, thus media use also affects physical and psychological health (Ohannessian, 2009).
It should be noted that one major problem with the displacement hypothesis is the assumption that if the targeted behavior were removed (e.
Although it is a logical to assume that TV replaces (or displaces) calorie-burning physical activity, there is surprisingly little evidence to support the displacement hypothesis.
The most important of these is the Horiuchi displacement hypothesis.

The competitive displacement hypothesis predicts that interspecific overlap in physical characteristics of nest sites will be greater for artificial vs.
The competitive displacement hypothesis predicted that both kittiwake species would display a preference for wide ledges located at low elevations, and that overlap of ledge characteristics of the two species would be greater for artificial than natural nest sites.
Figure 2 illustrates the general overview of the simulations and reconstructions used to test the character displacement hypothesis.
We resolved ambiguous nodes in four ways: by using the DELTRAN and ACCTRAN resolutions and by using Maximum-Transition and Minimum-Transition (customized resolutions that are potentially the most and least favorable to the character displacement hypothesis, as explained below, [ILLUSTRATION FOR FIGURE 3 OMITTED]).
Empirical evidence of correlations between predator size and prey size, necessary for support of the competitive character displacement hypothesis had been lacking in previous studies of character displacement in carnivores (Dayan et al.
