An example of upregulation is the response of liver cells exposed to such xenobiotic molecules as dioxin. In this situation, the cells increase their production of cytochrome P450 enzymes, which in turn increases degradation of these dioxin molecules. Downregulation or upregulation of an RNA or protein may also arise by an epigenetic alteration ...
"Behavioral sink" is a term invented by ethologist John B. Calhoun to describe a collapse in behavior that can result from overpopulation.The term and concept derive from a series of over-population experiments Calhoun conducted on Norway rats between 1958 and 1962. [1]
Maes and colleagues reported fifteen experiments that attempted to replicate the blocking effect. None of them succeeded despite using procedures well-established in previous literature. [ 5 ] They argue that publication bias may have produced a false confidence in the robustness of the effect. [ 6 ]
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.
The experiment depends on a particular social approach where the main source of information is the participants' point of view and knowledge. To carry out a social experiment, specialists usually split participants into two groups — active participants (people who take action in particular events) and respondents (people who react to the action).
Inhibitory control, also known as response inhibition, is a cognitive process – and, more specifically, an executive function – that permits an individual to inhibit their impulses and natural, habitual, or dominant behavioral responses to stimuli (a.k.a. prepotent responses) in order to select a more appropriate behavior that is consistent with completing their goals.
Tryon's Rat Experiment is a psychology experiment conducted by Robert Tryon in 1940 and published in the Yearbook of the National Society for Studies in Education. [1]
An example from the study, participants were able to form accurate impressions of the teachers by just watching 10-second, 5-second, and 2-second lengths of short video clips about teachers walking to classrooms. Ambady research provides support that nonverbal behavior has a strong influence on impression formation of teachers.
