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...

Listeners' interactions often take place in auditorily challenging conditions. We examined how noise affects phonological competition during spoken word recognition. In a visual-world experiment, which allows us to examine the time-course of recognition, English participants listened to target words in quiet and in noise while they saw four pictures on the screen: a target (e.g. candle), an ons...

The relative preference for a target product over a competitor can be increased by providing a third alternative (a "decoy") that is clearly inferior to the target but is not necessarily inferior to the competitor. In 3 experiments, we examined the conditions in which these decoy effects occur. When participants reported their preferences immediately after being exposed to the information about...

today, such organizations are successful and can continue to grow and survive in the competitive conditions that try to make use of thoughts and new ideas and identify needs and environmental opportunities and exploit to their benefit the actions that other organizations are doing in order to gain a competitive advantage and thereby, they can prevent the possible threats that will arise in the ...

In this paper, we formulate a three-species ecological community model consisting of two aphid species (Acyrthosiphon pisum and Megoura viciae) and a specialist parasitoid (Aphidius ervi) that attacks only one of the aphids (A pisum). The model incorporates both density-mediated and trait-mediated host-parasitoid interactions. Our analysis shows that the model possesses much richer and more rea...

Grounded in social facilitation theory, this study compared the impact on exercise intensity of a virtual versus a live competitor, when riding a virtual reality-enhanced stationary bike ("cybercycle"). It was hypothesized that competitiveness would moderate effects. Twenty-three female college students were exposed to three conditions on a cybercycle: solo training, virtual competitor, and liv...

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...

Competition structures ecological communities and alters host-pathogen interactions. In environmentally transmitted pathogens, an infection-resistant competitor may influence infection dynamics in a susceptible species through the negative impacts of competition (e.g., by reducing host density or causing nutritional stress that increases susceptibility to infection) and/or the positive impacts ...
