Strategic self-promotion and competitor derogation: sex and context effects on the perceived effectiveness of mate attraction tactics.
In this article, 7 evolutionary hypotheses about the context-specific nature of mate attraction effectiveness were empirically tested and supported. In the context of short-term mating, for example, men have faced the adaptive problem of finding sexually accessible women. As a result, men express a preference for sexually availability in short-term mates. In Studies 1 and 2, separate groups of ...
متن کاملLimit cycles for competitor–competitor–mutualist Lotka–Volterra systems
It is known that a limit cycle (or periodic coexistence) can occur in a competitor–competitor–mutualist Lotka–Volterra system ẋ1 = x1(r1 − a11x1 − a12x2 + a13x3), ẋ2 = x2(r2 − a21x1 − a22x2 + a23x3), ẋ3 = x3(r3 + a31x1 + a32x2 − a33x3), where ri , ai j are positive real constants [X.

متن کاملThe neuroecology of competitor recognition.
Territorial animals can be expected to distinguish among the types of competitors and noncompetitors that they encounter on a regular basis, including prospective mates and rivals of their own species, but they may not correctly classify individuals of other species. Closely related species often have similar phenotypes and this can cause confusion when formerly allopatric populations first com...
متن کاملThe Periodicity of Competitor Pricing
Pricing series reflect multiple decisions (e.g., regular pricing and discounting) often made by multiple decision makers. For example, temporary price reductions (high frequency price changes) can be used to price discriminate in the short run, while regular price adjustments (low frequency price changes) reflect more strategic or long-term goals. It is therefore not implausible that the “react...
متن کاملCompetitor Rule Suppression and Decay
The Competitor Rule Suppression (CRS) effect is the performance impairment observed in task switching when the currently relevant task rule is the same rule that had generated a response conflict in the preceding trial. This effect could reflect (a) episodic tagging, in which a competitor rule is retrieved with relative difficulty in subsequent trials or (b) residual active inhibition of the co...
