Sources of Self-Esteem II: Performance Feedback01:24

Sources of Self-Esteem II: Performance Feedback

195
Self-esteem is intricately tied to our perception of competence and our ability to exert control over our lives. One of the primary sources of this perception is performance feedback — the ongoing evaluation of our actions in terms of success and failure. According to Franks and Marolla (1976), people derive self-worth from experiencing themselves as causal agents, capable of achieving goals and overcoming obstacles. This process nurtures a critical component of self-esteem:...

Feedback Inhibition

57.3K
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!

Mutation, Gene Flow, and Genetic Drift01:09

Mutation, Gene Flow, and Genetic Drift

64.6K
In a population that is not at Hardy-Weinberg equilibrium, the frequency of alleles changes over time. Therefore, any deviations from the five conditions of Hardy-Weinberg equilibrium can alter the genetic variation of a given population. Conditions that change the genetic variability of a population include mutations, natural selection, non-random mating, gene flow, and genetic drift (small population size).

Instinctive Drift01:05

Instinctive Drift

819
Instinctive drift refers to the tendency of animals to revert to their innate behaviors despite repeated reinforcement. Breland and Breland demonstrated this concept in an experiment with a raccoon. The raccoon was trained to pick up two coins and place them in a container in exchange for food. Initially, the raccoon learned to associate the coins with food, making them a conditioned stimulus or a substitute for food. However, over time, the raccoon became less willing to put the coins into the...

Diffusion01:12

Diffusion

222.0K
Diffusion is the passive movement of substances down their concentration gradients—requiring no expenditure of cellular energy. Substances, such as molecules or ions, diffuse from an area of high concentration to an area of low concentration in the cytosol or across membranes. Eventually, the concentration will even out, with the substance moving randomly but causing no net change in concentration. Such a state is called dynamic equilibrium, which is essential for maintaining overall...

Drift Velocity01:19

Drift Velocity

5.6K
The high speed of electrical signals results from the fact that the force between charges acts rapidly at a distance. Thus, when a free charge is forced into a wire, the incoming charge pushes other charges ahead due to the repulsive force between like charges. These moving charges move the charges farther down the line. The density of charge in a system cannot easily be increased, so the signal is passed on rapidly. The resulting electrical shock wave moves through the system at nearly the...

Summary

Task-switching training improves performance by adjusting decision boundaries, not by enhancing learning. Feedback influences reaction times but does not impact overall task-switching skill acquisition.

Area of Science:

  • Cognitive Psychology
  • Neuroscience
  • Decision Making

Background:

  • Task-switching is crucial for adapting behavior in dynamic environments.
  • Previous training paradigms have faced challenges due to parameter sensitivity.
  • Understanding feedback's role is key to optimizing training.

Purpose of the Study:

  • To investigate the influence of different feedback types on task-switching.
  • To analyze changes in drift diffusion model parameters during task-switching training.
  • To determine how feedback affects cognitive processes underlying task-switching.

Main Methods:

  • 316 participants trained on a color/shape sorting task with varied feedback conditions.
  • Employed the Drift Diffusion Model (DDM) to analyze reaction time and accuracy.
  • Compared performance across six feedback groups, including no feedback and block feedback.

Main Results:

  • Feedback affected overall performance but not task-switching learning.
  • Reductions in reaction time switch cost were linked to a decreasing decision boundary.
  • Feedback modulated reaction time switch costs via decision boundary, not drift rate.

Conclusions:

  • Task-switching training modifies performance by altering decision boundaries.
  • Feedback influences the speed of decision-making but not the learning of task-switching.
  • Participants adapt their strategy without significant improvement in task-switching ability.
