  2. Avoidance response - Wikipedia

    en.wikipedia.org/wiki/Avoidance_response

    An avoidance response is a response that prevents an aversive stimulus from occurring. It is a kind of negative reinforcement . An avoidance response is a behavior based on the concept that animals will avoid performing behaviors that result in an aversive outcome.

  3. Three Rs (animal research) - Wikipedia

    en.wikipedia.org/wiki/Three_Rs_(animal_research)

    Replacement: methods which avoid the use of animals in research; Reduction: use of methods that enable researchers to minimise the number of animals necessary to obtain reliable and useful information. Refinement: use of methods that alleviate or minimize potential pain, suffering, distress, or lasting harm and improve welfare for the animals used.

  4. Pathogen avoidance - Wikipedia

    en.wikipedia.org/wiki/Pathogen_Avoidance

    Pathogen avoidance (also parasite avoidance or pathogen disgust) refers to the theory that the disgust response, in humans, is an adaptive system that guides behavior to avoid infection caused by parasites such as viruses, bacteria, fungi, protozoa, helminth worms, arthropods and social parasites.

  5. Fear - Wikipedia

    en.wikipedia.org/wiki/Fear

    The avoidance learning of rats is seen as a conditioned response, and therefore the behavior can be unconditioned, as supported by the earlier research. Species-specific defense reactions (SSDRs) or avoidance learning in nature is the specific tendency to avoid certain threats or stimuli, it is how animals survive in the wild.

  6. Murray Sidman - Wikipedia

    en.wikipedia.org/wiki/Murray_Sidman

    Methodologically, a "Sidman avoidance procedure" [10] is an experiment in which the subject is periodically presented with an aversive stimulus, such as the introduction of carbon dioxide or an electric shock, unless they engage in a particular response, such as pulling a plunger, which delays the stimulus by a certain amount of time.

  7. Avoidance reaction - Wikipedia

    en.wikipedia.org/wiki/Avoidance_reaction

    Avoidance reaction is a term used in the description of the movement of paramecium. This helps the cell avoid obstacles and causes other objects to bounce off of the cell's outer membrane . The paramecium does this by reversing the direction in which its cilia beat.

  8. Parasitology - Wikipedia

    en.wikipedia.org/wiki/Parasitology

    In fisheries biology, for example, parasite communities can be used to distinguish distinct populations of the same fish species co-inhabiting a region. Additionally, parasites possess a variety of specialized traits and life-history strategies that enable them to colonize hosts.

  9. Gain-of-function research - Wikipedia

    en.wikipedia.org/wiki/Gain-of-function_research

    Gain-of-function research (GoF research or GoFR) is medical research that genetically alters an organism in a way that may enhance the biological functions of gene products. This may include an altered pathogenesis , transmissibility , or host range , i.e., the types of hosts that a microorganism can infect.
