Phylogenetic Trees03:21

Phylogenetic Trees

49.3K
Phylogenetic trees come in many forms. It matters in which sequence the organisms are arranged from the bottom to the top of the tree, but the branches can rotate at their nodes without altering the information. The lines connecting individual nodes can be straight, angled, or even curved.

What is Behavior?

10.2K
Behaviors are actions that an organism engages in—they can be related to finding food, reproducing, defending against threats, and many other possible actions. Behaviors include activities related to the environment around the animal—such as migration—as well as social interactions within a species or population. Many behaviors involve motor output—that is, muscle movements—while others involve less visible actions, such as learning.

Behaviorism01:28

Behaviorism

4.7K
The field of behaviorism was pioneered by figures such as Ivan Pavlov, John B. Watson, and B.F. Skinner fundamentally shifted the focus of psychology to the observable and controllable aspects of human and animal behavior. This shift marked a critical evolution in the discipline, emphasizing scientific rigor and experimental methodology.
The core premise of behaviorism is its focus on observable behavior rather than internal thoughts or feelings. This approach argues that true scientific...

Electron Behavior

107.5K
Overview
Electrons are negatively charged subatomic particles that are attracted to an orbit around the positively-charged nucleus of an atom. They reside in locations that are associated with energy levels called shells and are further organized into sub-shells and orbitals within each shell.
Electrons Orbit the Nucleus
Electrons are found in specific locations outside of the nucleus. The shell in which an electron resides indicates the general energy level of the electron: those closer to the...

Plastic Behavior01:21

Plastic Behavior

535
A material's elastic behavior is characterized by the disappearance of stress once the load is removed, allowing the material to return to its original state. However, when stress surpasses the yield point, yielding commences, marking the onset of plastic deformation or permanent set. This change from elastic to plastic behavior is influenced by the peak stress value and the duration before the load is removed. An intriguing observation occurs when a specimen is loaded, unloaded, and...

Area of Science:

  • Neuroscience
  • Evolutionary Biology
  • Cognitive Science

Background:

  • Traditional cognitive science often relies on psychological definitions for putative functions.
  • These definitions may not accurately reflect underlying neurophysiological mechanisms.
  • A biologically grounded approach is needed to categorize brain functions.

Purpose of the Study:

  • To propose and demonstrate the method of phylogenetic refinement for constructing behavior theories.
  • To illustrate how evolutionary data can inform the delineation of neurophysiological mechanisms.
  • To offer a more biologically accurate framework for understanding brain function.

Main Methods:

  • Utilizing phylogenetic data to trace the evolutionary sequence of behavioral changes.
  • Applying 'phylogenetic refinement' to progressively elaborate theories from simple to complex.
  • Mapping the developed theoretical framework to existing neurophysiological and neuroanatomical data.

Main Results:

  • A theoretical framework for the evolution of feedback control in vertebrate brains was sketched.
  • This framework naturally maps to neurophysiological and neuroanatomical evidence.
  • The approach yields a conceptual taxonomy of mechanisms.

Conclusions:

  • Phylogenetic refinement offers a biologically plausible method for theory construction in behavior.
  • This method provides a superior basis for defining putative functions compared to traditional approaches.
  • The resulting taxonomy offers a more accurate biological grounding for cognitive science concepts.
