Lung Capacity01:47

Lung Capacity

56.3K
The air in the lungs is measured in volumes and capacities. Lung volume measures reflect the amount of air taken in, released, or left over after a lung function, like a single inhalation. Lung capacity measures are sums of two or more lung volume measures.

Cognitive Dissonance01:38

Cognitive Dissonance

37.5K
Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Respiratory Capacities01:24

Respiratory Capacities

1.4K
Respiratory capacities are crucial indicators of lung function, representing the maximum amount of air an individual's respiratory system can handle during various breathing phases.
One key metric is the Inspiratory Capacity (IC), which represents the maximum amount of air that can be inhaled with full effort. IC is calculated by summing the tidal volume and inspiratory reserve volume, typically ranging from 2.4 to 3.6 liters.
The Functional Residual Capacity (FRC) represents the air in the...

Buffers: Buffer Capacity01:09

Buffers: Buffer Capacity

2.3K
Buffer capacity is the quantitative measure of a buffer to resist the change in pH. As shown in the following equation, the buffer capacity, denoted by 'beta', is expressed as the number of moles of acid or base needed to change the pH of a one-liter buffer solution by 1 unit. Here, Ca and Cb indicate the number of moles of acid and base, respectively. Note that dpH represents the change in pH.
In the graph, pH is plotted as a function of the number of moles of base (Cb) added to a weak...

Respiratory Volumes and Capacities01:22

Respiratory Volumes and Capacities

5.4K
The respiratory system is responsible for the intake of oxygen and the expulsion of carbon dioxide from the body. Respiratory volumes describe the volume of air in the lungs at different phases of the respiratory cycle. Tidal volume is the air breathed in and out during normal, quiet breathing. Inspiratory reserve volume is the air that can be forcefully inspired beyond the tidal volume. In contrast, expiratory reserve volume refers to the air that can be expelled from the lungs after a normal...

Fast Fourier Transform01:10

Fast Fourier Transform

941
The Fast Fourier Transform (FFT) is a computational algorithm designed to compute the Discrete Fourier Transform (DFT) efficiently. By breaking down the calculations into smaller, manageable sections, the FFT significantly reduces the computational complexity involved. Direct computation of an N-point DFT requires N2 complex multiplications, whereas the FFT algorithm needs only (N/2)log⁡2N multiplications, offering a much faster performance.
The computational efficiency of the FFT becomes...

Summary

Fast Mapping, a lab task for learning new words, is now broadly used to describe children's innate abilities. Researchers argue this over-extension of the term is problematic for scientific understanding.

Area of Science:

  • Psycholinguistics
  • Child Development
  • Cognitive Science

Background:

  • Fast Mapping is a defined laboratory procedure for novel word acquisition.
  • The term's usage has expanded beyond its original experimental context.

Purpose of the Study:

  • To analyze the evolution of the term "Fast Mapping" in research literature.
  • To critique the broadening definition and its implications.

Main Methods:

  • Literature review of studies using the term "Fast Mapping".
  • Conceptual analysis of the term's application in different research contexts.

Main Results:

  • Researchers increasingly use "Fast Mapping" to describe internal cognitive processes, not just lab tasks.
  • The term is applied to children's everyday learning and inherent capacities.

Conclusions:

  • The over-extension of "Fast Mapping" risks diluting its specific meaning.
  • Clarifying the term's usage is essential for accurate scientific communication in child language acquisition research.
