  2. Biological applications of bifurcation theory - Wikipedia

    en.wikipedia.org/wiki/Biological_applications_of...

    As a very simple explanation of a bifurcation in a dynamical system, consider an object balanced on top of a vertical beam. The mass of the object can be thought of as the control parameter, r, and the beam's deflection from the vertical axis is the dynamic variable, x. As r increases, x remains relatively stable. But when the mass reaches a ...

  3. Scientific control - Wikipedia

    en.wikipedia.org/wiki/Scientific_control

    For example, if the fertilizer was spread by a tractor but no tractor was used on the unfertilized treatment, then the effect of the tractor needs to be controlled. A scientific control is an experiment or observation designed to minimize the effects of variables other than the independent variable (i.e. confounding variables). [1]

  4. Control variable - Wikipedia

    en.wikipedia.org/wiki/Control_variable

    A control variable (or scientific constant) in scientific experimentation is an experimental element which is constant (controlled) and unchanged throughout the course of the investigation. Control variables could strongly influence experimental results were they not held constant during the experiment in order to test the relative relationship ...

  5. Multiple object tracking - Wikipedia

    en.wikipedia.org/wiki/Multiple_object_tracking

    In psychology and neuroscience, multiple object tracking (MOT) refers to the ability of humans and other animals to monitor multiple moving objects. It is also the term for certain laboratory techniques used to study this ability. In an MOT study, several identical moving objects are presented on a display.

  6. Design of experiments - Wikipedia

    en.wikipedia.org/wiki/Design_of_experiments

    To control for nuisance variables, researchers institute control checks as additional measures. Investigators should ensure that uncontrolled influences (e.g., source credibility perception) do not skew the findings of the study. A manipulation check is one example of a control check. Manipulation checks allow investigators to isolate the chief ...

  7. Living systems - Wikipedia

    en.wikipedia.org/wiki/Living_systems

    A closely related approach, relational biology, is concerned mainly with understanding life processes in terms of the most important relations, and categories of such relations among the essential functional components of organisms; for multicellular organisms, this has been defined as "categorical biology", or a model representation of ...

  8. Macroscope (science concept) - Wikipedia

    en.wikipedia.org/wiki/Macroscope_(science_concept)

    In science, the concept of a macroscope is the antithesis of the microscope, namely a method, technique or system appropriate to the study of very large objects or very complex processes, for example the Earth and its contents, [1] [2] or conceptually, the Universe. Obviously, a single system or instrument does not presently exist that could ...

  9. Habituation - Wikipedia

    en.wikipedia.org/wiki/Habituation

    There is an additional connotation to the term habituation which applies to psychological dependency on drugs, and is included in several online dictionaries. [6] A team of specialists from the World Health Organization assembled in 1957 to address the problem of drug addiction and adopted the term "drug habituation" to distinguish some drug-use behaviors from drug addiction.
