What is Behavior?00:54

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

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

542
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...

Behavior Therapy01:22

Behavior Therapy

Behavior therapy incorporates diverse techniques rooted in classical conditioning principles to address maladaptive behaviors and anxiety disorders. These methods aim to reduce avoidance behaviors, foster adaptive coping mechanisms, and alter associations between stimuli and responses, making them effective in a wide range of therapeutic contexts.
Exposure therapy is a cornerstone of behavioral treatment for anxiety disorders. It involves systematic exposure to feared stimuli, either in real...

This summary is machine-generated.

Increasing hunger reduces social behaviors in mice, while social interactions can influence feeding. Intense hunger, particularly from AgRP photoactivation, alters behavioral choices based on food availability.

Area of Science:

  • Neuroscience
  • Behavioral Biology
  • Animal Behavior

Background:

  • Organisms must integrate internal states and external cues for optimal decision-making.
  • Hunger and social motivations are fundamental drives that can compete for behavioral control.

Purpose of the Study:

  • To investigate the interplay between hunger and social behaviors in mice.
  • To determine how hunger intensity affects social interactions and how social interactions influence feeding.

Main Methods:

  • Utilized a resident-intruder paradigm to observe mouse social behavior and feeding.
  • Manipulated hunger states, including using AgRP photoactivation.
  • Analyzed behavioral sequences and the impact of social context on feeding.

Main Results:

  • Elevated hunger significantly decreased social interactions (mating, territorial aggression) in resident mice.
  • Intense hunger, especially via AgRP photoactivation, altered behavioral choice sequences, contingent on food availability.
  • Female intruder presence attenuated resident mouse feeding, while male intruder presence did not.
  • Intruding mice exhibited context-dependent feeding behaviors, influenced by environmental cues.

Conclusions:

  • Hunger intensity inversely correlates with social behavior engagement in mice.
  • Social interactions, particularly with females, can suppress feeding behavior.
  • Environmental context dynamically modulates feeding behavior expression in mice.
