Fixed Action Patterns

16.6K
A fixed action pattern (FAP) is a specific, hard-wired sequence of behaviors that occurs in response to an external stimulus, called a sign stimulus. The behavior is “fixed” because it is essentially unchangeable—proceeding similarly across individuals of a species every time it occurs.

Automatic Processing and Automatic Social Behavior

21
Automatic processing refers to the cognitive operations that occur without conscious intent or awareness, playing a fundamental role in shaping social cognition and behavior. These processes enable individuals to navigate complex social environments efficiently by relying on mental shortcuts and pre-existing knowledge structures known as schemas. One of the most influential mechanisms underlying automatic processing is priming, which subtly activates mental representations through exposure to...

Area of Science:

  • Computer Vision
  • Artificial Intelligence

Background:

  • Human action recognition is a key area in computer vision.
  • Existing methods often focus on clip-level recognition using appearance and motion features.
  • Traditional approaches frequently analyze entire images, limiting instance-specific detail.

Purpose of the Study:

  • To propose a new framework for human instance-level video action recognition.
  • To develop a more discriminative approach by focusing on individual human instances.
  • To enhance the understanding of temporal dynamics in human actions.

Main Methods:

  • Developed a framework representing instance-level features using human bounding boxes and keypoints.
  • Utilized action region features as input for a novel temporal action head network.
  • Designed temporal action head networks with modules to capture diverse temporal dynamics.

Main Results:

  • The proposed framework achieved performance comparable to state-of-the-art methods on challenging datasets.
  • Evaluated the effectiveness of proposed features and network modules.
  • Demonstrated human instance-level action recognition in scenarios with multiple individuals.

Conclusions:

  • The proposed human instance-level framework offers a more discriminative approach to video action recognition.
  • Novel temporal action head networks effectively capture complex temporal action dynamics.
  • The method shows promise for real-world applications involving multi-person interactions.
