Fixed Action Patterns01:06

Fixed Action Patterns

16.1K
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.

Timing and Consequences on Behavior

119
In operant conditioning, the timing of reinforcement is crucial. For animals like rats and cats, immediate reinforcement (within a few seconds) is much more effective than delayed reinforcement. For example, a food reward for a rat needs to follow within 30 seconds of pressing a bar to be effective. 
Humans, however, can respond to delayed reinforcers. We often make decisions between immediate small rewards and delayed larger rewards. This ability to delay gratification is a significant...

Osmoregulation in Fishes

When cells are placed in a hypotonic (low-salt) fluid, they can swell and burst. Meanwhile, cells in a hypertonic solution—with a higher salt concentration—can shrivel and die. How do fish cells avoid these gruesome fates in hypotonic freshwater or hypertonic seawater environments?

Instinctive Drift01:05

Instinctive Drift

250
Instinctive drift refers to the tendency of animals to revert to their innate behaviors despite repeated reinforcement. Breland and Breland demonstrated this concept in an experiment with a raccoon. The raccoon was trained to pick up two coins and place them in a container in exchange for food. Initially, the raccoon learned to associate the coins with food, making them a conditioned stimulus or a substitute for food. However, over time, the raccoon became less willing to put the coins into the...

What is Behavior?00:54

What is Behavior?

9.0K
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.

Summary

Fish learn how their actions create sensory feedback, adapting this knowledge based on their surroundings. This study reveals context-dependent learning in animal internal models.

Area of Science:

  • Neuroscience
  • Animal Behavior

Background:

  • Animals build internal models to predict sensory consequences of behaviors.
  • Understanding how these models adapt to environmental changes is crucial.

Purpose of the Study:

  • To investigate if animals learn context-specific sensory predictions for a single behavior.
  • To explore the flexibility of internal models in response to local environmental cues.

Main Methods:

  • Utilized freely moving fish as a model organism.
  • Observed behavioral responses and sensory feedback in varying local contexts.

Main Results:

  • Demonstrated that fish learn context-dependent sensory outcomes for a specific behavior.
  • Evidence suggests internal models are updated based on local environmental information.

Conclusions:

  • Freely moving fish exhibit adaptive learning of behavior-outcome associations.
  • Sensory predictions are not static but dynamically updated by environmental context.
