Undermatching is an emergent property of selection by consequences

Behavioural Processes, 2007
A computational theory of selection by consequences [McDowell, J.J, 2004. A computational model of selection by consequences. J. Exp. Anal. Behav. 81, 297-317] was tested by studying the responding of virtual organisms that were animated by the theory on random interval schedules of reinforcement.

Learning as a Consequence of Selection

2002
Since the end of the XIXth century, the influence of learning on natural selection has been considered. More recently, this influence has been investigated using computer simulations. However, it has not yet been shown how the ability of learning can be the product of natural selection. This point is precisely the subject of this paper.

Selection by consequences

Behavioral and Brain Sciences, 1981
AbstractHuman behavior is the joint product of (i) contingencies of survival responsible for natural selection, and (ii) contingencies of reinforcement responsible for the repertoires of individuals, including (iii) the special contingencies maintained by an evolved social environment.

Demographic Consequences of Natural Selection

1987
From the standpoint of most people’s interests and perspectives, little need be added to the simple and elegant statement above. From the special perspective of a student of evolution, the statement seems a trifle parochial, and some qualifications and additions seem justified.

The effects and consequences of selected club drugs

Journal of Substance Abuse Treatment, 2002
Ecstasy (MDMA), gamma-hydroxybutyrate (GHB), ketamine, and methamphetamine are 4 examples of club drugs that are increasing in popularity. Although the pharmacological classifications of these drugs vary, MDMA has structural similarities to both amphetamine and the hallucinogen mescaline.

Canine fertility: The consequences of selection for special traits

Reproduction in Domestic Animals, 2020
AbstractPedigree dogs and cats are bred aiming to conform breed standards with very poor consideration for breeding stock fertility. At the same time, the genetic asset underlining reproductive traits could be effectively analysed like in other species under selection.
