Milgram's Obedience to Authority02:20

Milgram's Obedience to Authority

6.0K
Obedience to authority is classically demonstrated in a more famous series of social psychology experiments performed by Stanley Milgram. He was a social psychology professor at Yale who was influenced by the trial of Adolf Eichmann, a Nazi war criminal. Eichmann’s defense for the atrocities he committed was that he was “just following orders.”

Techniques of therapeutic communication I: Active Listening, Sharing Observations, Validation, and Using Touch

8.0K
The history of therapeutic communication can be traced back to Florence Nightingale, who emphasized the importance of developing trusting relationships with patients. She taught that the presence of nurses with patients results in therapeutic healing.
Therapeutic communication is not the same as social interaction. Social interaction has no goal or purpose and consists of casual information sharing, whereas therapeutic communication has a plan or purpose for the conversation. Therapeutic...

Sensory Modalities01:15

Sensory Modalities

4.1K
Sensation typically is the process by which the sensory receptors and sense organs detect stimuli from the internal and external environment and transmit this information to the central nervous system for processing.
General senses refer to the broad category of sensory information detected by receptors in the body and can be further grouped into somatic and visceral senses. Somatic sensations include touch, pressure, temperature, and pain and are essential for navigating our environment and...

Design Example: Resistive Touchscreen

949
A device engineer plays a crucial role in designing user interfaces for mobile devices. One such interface is the resistive touchscreen, which fundamentally consists of two metallic layers: a flexible upper layer and a rigid lower layer, separated by a narrow gap. The high resistance between these two layers is a key characteristic of this design.
When a user touches the screen, the two layers make contact at a specific point known as the touchpoint. This contact reduces the resistance between...

Classical Conditioning in Daily Life01:17

Classical Conditioning in Daily Life

2.9K
Classical conditioning, a fundamental principle of associative learning, explains various phenomena observed in daily life, such as fear development, the placebo effect, taste aversion, and drug habituation. These applications demonstrate the profound impact of associative learning on human behavior and physiological responses.
John B. Watson and Rosalie Rayner famously demonstrated the development of fear through classical conditioning in their experiment with Little Albert. They paired the...

Factors Influencing Attraction I: Proximity

434
Proximity plays a fundamental role in shaping interpersonal attraction by increasing opportunities for interaction and fostering familiarity. Research consistently demonstrates that individuals are more likely to form social bonds with those who are physically closer to them, whether in residential settings, workplaces, or educational institutions. This effect is largely driven by the increased frequency of encounters, which facilitates the development of friendships and romantic...

Area of Science:

  • Robotics
  • Artificial Intelligence
  • Machine Learning

Background:

  • Dexterous manipulation is a key challenge for autonomous robots.
  • Learning to lift and rotate objects with intermittent finger contacts is particularly difficult.

Purpose of the Study:

  • To investigate the impact of curriculum design and haptic feedback on learning dexterous manipulation.
  • To compare the effectiveness of no-tactile versus 3D-force sensing.

Main Methods:

  • Model-free reinforcement learning was employed with a simulated three-finger robotic hand.
  • A novel curriculum-based learning rate scheduler was developed to accelerate convergence.

Main Results:

  • The choice of curriculum significantly influenced the learning progression for dexterous manipulation across various objects.
  • Robotic hand successfully learned manipulation tasks even without haptic information, demonstrating robustness.

Conclusions:

  • Curriculum learning is a robust approach for teaching robots dexterous manipulation.
  • Haptic information may not be necessary for complex manipulation tasks, challenging conventional wisdom.
