Effects of feedback01:24

Effects of feedback

771
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...

Facial Feedback Hypothesis

340
Charles Darwin proposed that facial expressions are an evolutionary adaptation for communication. He argued that these expressions are not influenced by culture but are universal across species. For example, a snarling expression with exposed teeth signals a threat in many animals, including humans. Darwin also suggested that displaying an emotion can intensify the feeling. Smiling, for example, could enhance one's sense of happiness. This idea laid the foundation for understanding the role...

Area of Science:

  • Linguistics
  • Speech Science
  • Educational Technology

Background:

  • Language acquisition is multimodal, involving auditory and visual information.
  • Pronunciation improvement benefits from understanding articulatory movements.
  • Computer-assisted pronunciation training (CAPT) offers new feedback modalities.

Purpose of the Study:

  • To survey the literature on computer-assisted visual articulation feedback for language learners.
  • To categorize visual feedback into direct and indirect methods.
  • To discuss effective feedback delivery and evaluation.

Main Methods:

  • Literature review of computer-assisted visual articulation feedback.
  • Focus on segmental features of speech production.
  • Analysis of direct (visual models) and indirect (visualized acoustics) feedback.

Main Results:

  • Visual feedback in CAPT can model articulatory configurations and movements.
  • Visualized acoustic information can inform articulation instruction.
  • Effective feedback delivery criteria and evaluation methods are considered.

Conclusions:

  • Visual articulation feedback is a valuable component of multimodal language learning.
  • Further research can optimize the design and implementation of visual feedback in CAPT.
  • Integrating visual feedback enhances the efficacy of pronunciation training.
