Avoidance Learning and Learned Helplessness01:14

Avoidance Learning and Learned Helplessness

2.6K
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...

Social Proof

32.4K
Social proof is a form of persuasion based on comparison and conformity. People compare their behavior and actions to what others are doing and will change to conform to do what their peers do.

Types Of Collisions - I

9.5K
When two objects come in direct contact with each other, it is called a collision. During a collision, two or more objects exert forces on each other in a relatively short amount of time. A collision can be categorized as either an elastic or inelastic collision. If two or more objects approach each other, collide and then bounce off, moving away from each other with the same relative speed at which they approached each other, the total kinetic energy of the system is said to be conserved. This...

Types of Collisions - II

10.0K
When two or more objects collide with each other, they can stick together to form one single composite object (after collision). The total mass of the object after the collision is the sum of the masses of the original objects, and it moves with a velocity dictated by the conservation of momentum. Although the system's total momentum remains constant, the kinetic energy decreases, and thus such a collision is an inelastic collision. Most of the collisions between objects in daily life are...

The Sense of Self: Reflected Self-Appraisal and Social Comparison

56.1K
According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...

Frustration and Conflict: Avoidance-Avoidance, Double-Approach Avoidance

692
Avoidance-avoidance conflict refers to a psychological situation where a person must choose between two or more unpleasant alternatives. These conflicts are particularly stressful because neither option is desirable. This dilemma is often expressed in sayings like "caught between a rock and a hard place" or "between the devil and the deep blue sea." For instance, individuals who fear dental procedures may find themselves torn between enduring a painful toothache or facing the...

Area of Science:

  • Robotics
  • Human-Robot Interaction
  • Artificial Intelligence

Background:

  • Social robots require sophisticated gesture generation for effective human interaction.
  • Modeling complex, multi-jointed arm gestures poses challenges due to high-dimensional robot configurations.
  • Imitation learning offers a method to teach robots gestures by observing human movements.

Purpose of the Study:

  • To develop a novel imitation learning system for social robots capable of performing multi-jointed arm gestures.
  • To integrate self-collision awareness and avoidance mechanisms into the robot's gesture execution.
  • To evaluate the system's effectiveness in mimicking human gestures while ensuring robot safety.

Main Methods:

  • Utilized imitation learning to map observed human arm movements to robot arm trajectories.
  • Implemented a kinematical approach incorporating bounding volumes for self-collision detection.
  • Employed a non-contact 3D sensor for capturing human teacher's gestures.
  • Conducted experiments using a dual-arm social robot platform.

Main Results:

  • The proposed system successfully enabled the social robot to mimic human gestures.
  • The self-collision avoidance system effectively detected and prevented collisions during gesticulation.
  • Demonstrated the feasibility of learning and executing complex gestures safely.

Conclusions:

  • The novel imitation learning system enhances social robot capabilities for naturalistic human interaction.
  • Robot self-collision awareness is crucial for safe and effective gesture performance.
  • This approach provides a robust method for teaching robots complex motor skills through observation.
