Effects of feedback01:24

Effects of feedback

1.1K
Feedback in control systems plays a critical role in shaping various operational parameters, extending beyond simple error reduction to influence stability, bandwidth, gain, impedance, and sensitivity. Understanding these effects requires examining a basic feedback system characterized by defined input, output, error, and feedback signals.
Feedback significantly modifies the gain of a control system. The gain of a system without feedback is altered by a factor of one plus GH, where G represents...

Social Facilitation01:04

Social Facilitation

29.0K
Not all intergroup interactions lead to negative outcomes. Sometimes, being in a group situation can improve performance. Social facilitation occurs when an individual performs better when an audience is watching than when the individual performs the behavior alone. This typically occurs when people are performing a task for which they are skilled.

Social Scripts02:10

Social Scripts

8.7K
People tend to know what behavior is expected of them in specific, familiar settings. A script is a person’s knowledge about the sequence of events expected in a specific setting (Schank & Abelson, 1977). Essentially, scripts are a particular kind of schema, one containing default values for the features within an event. In the restaurant example, the script's features include the props (e.g., tables, menu, food, and money), the roles to be played (e.g., customer and waiter),...

Feedback control systems01:26

Feedback control systems

793
Feedback control systems are categorized in various ways based on their design, analysis, and signal types.
Linear feedback systems are theoretical models that simplify analysis and design. These systems operate under the principle that their output is directly proportional to their input within certain ranges. For instance, an amplifier in a control system behaves linearly as long as the input signal remains within a specific range. However, most physical systems exhibit inherent nonlinearity...

Communication01:28

Communication

9.8K
Sharing information, concepts, and emotions to foster mutual understanding is communication. The sender, recipient, and transaction must be considered in this manner. The sender is the person who shares the message, the recipient is the person who receives and understands the message, and the transaction is the method used to deliver the message and the variables that affect the communication's context and surroundings. The nurse-client connection is built on therapeutic communication.

Positive and Negative Feedback Loops01:18

Positive and Negative Feedback Loops

14.8K
Animal organs and organ systems constantly adjust to internal and external changes through a process called homeostasis ("steady state"). Examples of these changes include regulation of the level of glucose or calcium in the blood or internal responses to external temperatures. Homeostasis requires  maintaining an internal dynamic equilibrium:

Area of Science:

  • Cognitive Psychology
  • Behavioral Economics
  • Neuroscience

Background:

  • Effective decision-making hinges on adapting behavior to evolving environmental feedback.
  • Understanding the mechanisms of behavioral adaptation, including strategy reuse and change, is crucial for explaining flexible decision-making.

Purpose of the Study:

  • To investigate how feedback valence (reinforcement vs. punishment) and consistency influence the reuse of previously learned strategies versus the adoption of new ones.
  • To examine the impact of negative outcomes on learning new information versus relearning old information.

Main Methods:

  • Three experiments (N=218) using a competitive number-selection game with computerized opponents exhibiting exploitable patterns.
  • Manipulation of win rates during a 'During' phase to provide consistent reinforcement or punishment, disrupting or reinforcing pre-learned patterns.
  • Measurement of performance (win rate) and optimal behavior rate (OBR) across 'Pre,' 'During,' and 'Post' phases.

Main Results:

  • Participants aligning behavior with 'During' feedback were more likely to reuse prior patterns when they became advantageous again.
  • Stronger suppression of prior patterns during 'During' phase predicted better learning of new patterns later.
  • Negative outcomes selectively impaired learning new information while sparing relearning old information, suggesting response inertia and differential flexibility after wins versus losses.

Conclusions:

  • Behavioral adaptation involves a dynamic interplay between reusing established patterns and learning new ones, guided by feedback.
  • The valence and consistency of feedback significantly shape strategic behavior, influencing the balance between stability and flexibility.
  • Negative feedback may promote behavioral inertia, hindering the adoption of novel strategies while facilitating the retention of previously learned ones.
