Reinforcement, under his definition, included prezygotic divergence and complete post-zygotic isolation. [18] Servedio and Noor include any detected increase in prezygotic isolation as reinforcement, as long as it is a response to selection against mating between two different species. [4]
Secondary contact is the process in which two allopatrically distributed populations of a species are geographically reunited. This contact allows for the potential for the exchange of genes, dependent on how reproductively isolated the two populations have become.
The experimental analysis of behavior is a science that studies the behavior of individuals across a variety of species. A key early scientist was B. F. Skinner who discovered operant behavior, reinforcers, secondary reinforcers, contingencies of reinforcement, stimulus control, shaping, intermittent schedules, discrimination, and generalization.
Studies of reinforcement in nature often prove difficult, as alternative explanations for the detected patterns can be asserted. [3]: 358 Nevertheless, empirical evidence exists for reinforcement occurring across various taxa [7] and its role in precipitating speciation is conclusive. [8]
Of the concepts and procedures described in this article, a few of the most salient are the following: (a) availability of primary reinforcement (e.g. a bag of dog yummies); (b) the use of secondary reinforcement, (e.g. sounding a clicker immediately after a desired response, then giving yummy); (c) contingency, assuring that reinforcement (e.g ...
Operant conditioning chamber for reinforcement training. In behavioral psychology, reinforcement refers to consequences that increase the likelihood of an organism's future behavior, typically in the presence of a particular antecedent stimulus. [1] For example, a rat can be trained to push a lever to receive food whenever a light is turned on.
The biological basis of personality is a collection of brain systems and mechanisms that underlie human personality. Human neurobiology, especially as it relates to complex traits and behaviors, is not well understood, but research into the neuroanatomical and functional underpinnings of personality are an active field of research.
In 1951, the Brelands wrote an article titled "A Field of Applied Animal Psychology", where they proposed that modern behavioral science and professional animal training be brought together through applied animal psychology. [9] In the late 1950s into the early 1960s, they promoted and patented a dog and clicker training program called Master Mind.
