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...

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:

Biochemical reactions are occurring constantly in cells, converting starting substances to different products, usually with the help of enzymes that speed the reactions. Without enzymes, it would take far too long for most reactions to occur to be useful to the cell!

Frequency-dependent Selection01:21

Frequency-dependent Selection

24.3K
When the fitness of a trait is influenced by how common it is (i.e., its frequency) relative to different traits within a population, this is referred to as frequency-dependent selection. Frequency-dependent selection may occur between species or within a single species. This type of selection can either be positive—with more common phenotypes having higher fitness—or negative, with rarer phenotypes conferring increased fitness.

Stereotype Threat and Self-fulfilling Prophecies

42.8K
When we hold a stereotype about a person, we have expectations that he or she will fulfill that stereotype. A self-fulfilling prophecy is an expectation held by a person that alters his or her behavior in a way that tends to make it true. When we hold stereotypes about a person, we tend to treat the person according to our expectations. This treatment can influence the person to act according to our stereotypic expectations, thus confirming our stereotypic beliefs. Research by Rosenthal and...

In most cases, excessive hormone production is prevented by negative feedback—a loop that starts with a stimulus inducing the release of a particular substance, like a hormone, to maintain a certain level before triggering a signal that results in a decrease in further release of the hormone.

Summary
This summary is machine-generated.

Choice preference is linked to brain activity, specifically the feedback-negativity (FN) component of event-related potentials (ERPs), but not the P300. This suggests reinforcers signal future rewards, influencing behavior via the FN.

Area of Science:

  • Neuroscience
  • Cognitive Psychology
  • Behavioral Economics

Background:

  • Understanding choice mechanisms is key to human behavior.
  • Event-related potentials (ERPs), including feedback-negativity (FN) and P300, are linked to reward processing and learning.
  • The relationship between developing choice preferences and these neural correlates requires further investigation.

Purpose of the Study:

  • To investigate how individual choice preferences predict feedback-negativity (FN) and P300 amplitudes.
  • To explore the neural underpinnings of preference formation in decision-making.

Main Methods:

  • A two-alternative choice task with dependently scheduled reinforcer rates.
  • Quantification of choice preference using generalized matching law sensitivity and stay preference.
  • Hierarchical Bayesian linear regression to analyze the relationship between stay preference and ERP amplitudes.

Main Results:

  • Stay preference was significantly influenced by reinforcer ratios.
  • Stay preference credibly predicted feedback-negativity (FN) amplitude.
  • No significant prediction of P300 amplitude by stay preference was found.

Conclusions:

  • Reinforcers may guide behavior by signaling future reward, with the FN potentially reflecting this process.
  • The findings support a role for the FN in mediating the influence of reward information on choice behavior.
  • The P300 may not be directly involved in the development of choice preference in this context.
