For example, the hemipteran Arachnocoris berytoides resembles Faiditus caudatus, a spider commensal of ants. [34] In cryptic aggressive mimicry, the predator mimics an organism that its prey is indifferent to. This allows the predator to avoid detection until the prey are close enough for the predator to strike, effectively a form of camouflage.
Thus, prey feature detection is not an all-or-nothing condition, but rather a matter of degree: the greater an object's releasing value as a prey stimulus, the stronger is prey-selective T5.2 neuron's discharge frequency, the shorter is toad's prey-catching response latency, and the higher is the number of prey-catching responses during a ...
The psychology scholar Robert Mitchell identifies four levels of deception in animals. At the first level, as with protective mimicry like false eyespots and camouflage, the action or display is inbuilt. At the second level, an animal performs a programmed act of behaviour, as when a prey animal feigns death to avoid being eaten.
Predator–prey coevolution often makes it unfavorable for a predator to consume certain prey items, since many anti-predator defenses increase handling time. [16] Examples include porcupine quills, the palatability and digestibility of the poison dart frog, crypsis, and other predator avoidance behaviors. In addition, because toxins may be ...
The Barnum effect, also called the Forer effect or, less commonly, the Barnum–Forer effect, is a common psychological phenomenon whereby individuals give high accuracy ratings to descriptions of their personality that supposedly are tailored specifically to them, yet which are in fact vague and general enough to apply to a wide range of people.

A content rating (also known as maturity rating) [1] [2] rates the suitability of TV shows, movies, comic books, or video games to this primary targeted audience. [ 3 ] [ 4 ] [ 5 ] A content rating usually places a media source into one of a number of different categories, to show which age group is suitable to view media and entertainment.
For example, most examples of a match or mismatch rely on predator fitness that is dependent on a single resource. [ 4 ] [ 6 ] [ 2 ] However, even more generalist species can suffer from phenological and/or nutritional mismatch if their main food source is highly seasonal or varies in quality throughout key periods of the annual cycle such as ...
Example 1: The straightforward single round prisoner's dilemma game. The classic prisoner's dilemma game payoffs gives a player a maximum payoff if they defect and their partner co-operates (this choice is known as temptation). If, however, the player co-operates and their partner defects, they get the worst possible result (the suckers payoff).
