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:...

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!

Benefits of Self-Esteem

212
Self-esteem—an individual's overall evaluation of their worth—plays a complex role in psychological functioning and well-being. It is often associated with many positive traits, such as confidence, optimism, and perseverance. Individuals with high self-esteem typically experience better sleep, manage peer pressure more effectively, and report greater life satisfaction. Conversely, low self-esteem has been consistently linked with increased risks of depression, anxiety, and poor...

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.

Effects of feedback

1.0K
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...

Feedback control systems

727
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...

Summary

Learners often prefer feedback on accurate trials, but this study found it hinders skill acquisition. Choosing feedback on less accurate performances may improve learning and retention of motor skills.

Area of Science:

  • Motor Learning
  • Cognitive Psychology
  • Human Performance

Background:

  • Learners often prefer knowledge of results (KR) for accurate trials.
  • This preference's impact on skill acquisition, retention, and transfer is not fully understood.
  • Previous studies relied on self-report, not direct behavioral measures of KR preference.

Purpose of the Study:

  • To investigate if KR preference for accurate trials benefits skill acquisition.
  • To examine the effects of self-selected KR on motor learning, retention, and transfer.
  • To assess sensorimotor learning in a motion extrapolation task under different KR conditions.

Main Methods:

  • Participants performed a 90-trial motion extrapolation task.
  • Learners chose between KR on best or worst trials every three attempts.
  • Retention and transfer tests were conducted 24 hours post-acquisition without KR.

Main Results:

  • A preference for KR on accurate trials was observed, aligning with prior research.
  • Participant KR preferences were inconsistent throughout the acquisition phase.
  • KR on accurate performances negatively impacted skill acquisition and retention.

Conclusions:

  • Learners' preferred KR (accurate trials) can be detrimental to skill acquisition.
  • Self-selection of KR does not guarantee optimal learning outcomes.
  • Rethinking KR strategies may be necessary to maximize motor learning and retention.
