Avoidance Learning and Learned Helplessness

1.9K
Avoidance learning and learned helplessness are critical concepts in understanding behavioral responses to negative stimuli.
Avoidance learning occurs when an organism learns that a specific behavior can prevent an unpleasant outcome. For example, a student who receives a bad grade may start studying harder to avoid future poor grades. This behavior persists even when the negative outcome is no longer present. Avoidance learning is powerful because it maintains behavior in the absence of the...

Observational Learning01:12

Observational Learning

286
Albert Bandura's observational learning, also known as imitation or modeling, occurs when a person observes and imitates another's behavior. It is a quicker process than operant conditioning. A well-known example is the Bobo doll study, where children who saw an adult acting aggressively towards the doll were more likely to act aggressively when left alone, compared to those who observed a nonaggressive adult. Many psychologists view observational learning as a form of latent learning...

Reinforcement

315
Positive and negative reinforcement are key concepts in operant conditioning, a learning process where the consequences of a behavior affect the likelihood of that behavior being repeated.
Positive reinforcement occurs when a behavior is followed by the presentation of a rewarding stimulus, increasing the frequency of that behavior. For example:

Area of Science:

  • Computer Science
  • Electrical Engineering
  • Network Security

Background:

  • Wireless Sensor Networks (WSNs) face challenges in target-barrier coverage, particularly detecting intrusions from within a protected area.
  • Existing target-barrier solutions struggle with timely internal breach detection due to distance constraints.
  • Monitoring both external intrusions and internal targets is crucial for comprehensive WSN security.

Main Methods:

  • Developed the Convex Hull Attraction (CHA) algorithm for target-barrier construction, involving target clustering and sensor replacement.
  • Introduced the UAV-Enhanced Coverage (QUEC) algorithm, utilizing reinforcement learning for optimal Unmanned Aerial Vehicle (UAV) path planning.
  • Integrated CHA and QUEC to ensure continuous monitoring and rapid response to potential breaches.

Main Results:

  • CHA significantly reduces sensor count and extends target-barrier lifetime compared to TBC and VFA.
  • QUEC outperforms the Traveling Salesman Problem (TSP) in reducing UAV coverage time and improving energy efficiency.
  • The integrated approach enhances the efficiency of detecting targets breaching from inside.
