Perception of Sound Waves

Perception of Sound Waves

The human ear is not equally sensitive to all frequencies in the audible range. It may perceive sound waves with the same pressure but different frequencies as having different loudness. Moreover, the perception of sound waves depends on the health of an individual's ears, which decays with age. The health of one's ears may also be affected by regular exposure to loud noises.
The pitch of a sound depends on the frequency and the pressure amplitude of the source. Two sounds of the same...

Language and Cognition

Language and Cognition

Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.

Linear Approximation in Frequency Domain

Linear Approximation in Frequency Domain

Linear systems are characterized by two main properties: superposition and homogeneity. Superposition allows the response to multiple inputs to be the sum of the responses to each individual input. Homogeneity ensures that scaling an input by a scalar results in the response being scaled by the same scalar.
In contrast, nonlinear systems do not inherently possess these properties. However, for small deviations around an operating point, a nonlinear system can often be approximated as linear....

Damped Oscillations

Damped Oscillations

In the real world, oscillations seldom follow true simple harmonic motion. A system that continues its motion indefinitely without losing its amplitude is termed undamped. However, friction of some sort usually dampens the motion, so it fades away or needs more force to continue. For example, a guitar string stops oscillating a few seconds after being plucked. Similarly, one must continually push a swing to keep a child swinging on a playground.
Although friction and other non-conservative...

Language Development

Language Development

Children master language quickly and with relative ease, supported by both biological predisposition and reinforcement. B. F. Skinner (1957) proposed that language is learned through reinforcement, while Noam Chomsky (1965) argued that language acquisition mechanisms are biologically determined.
The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...

Oscillations about an Equilibrium Position

Oscillations about an Equilibrium Position

Stability is an important concept in oscillation. If an equilibrium point is stable, a slight disturbance of an object that is initially at the stable equilibrium point will cause the object to oscillate around that point. For an unstable equilibrium point, if the object is disturbed slightly, it will not return to the equilibrium point. There are three conditions for equilibrium points—stable, unstable, and half-stable. A half-stable equilibrium point is also unstable, but is named so...

Background:

Neuronal oscillations are thought to optimize sensory processing, including speech tracking.
The mechanism by which synchronized brain oscillations track pseudo-rhythmic speech remains unclear.

Purpose of the Study:

To propose and validate a model where neuronal oscillations track pseudo-rhythmic speech by incorporating predictions from internal language models.
To investigate the role of word predictability in speech temporal dynamics.

Main Methods:

Development of a computational model incorporating oscillations, feedback, and inhibition.
Analysis of speech temporal dynamics based on word predictability.
Simulation of the model's ability to track pseudo-rhythmic speech and generate temporal phase codes.

Main Results:

Speech temporal dynamics are significantly influenced by word predictability within sentences.
The computational model successfully tracks pseudo-rhythmic speech input.
The model generates temporal phase codes, a potential mechanism for information encoding.
The model demonstrates sensitivity to natural speech dynamics and explains temporal speech illusions.

Conclusions:

Neuronal tracking of pseudo-rhythmic speech can leverage internal language model predictions, not just acoustics.
Interactions between brain oscillations and language model constraints are crucial for speech processing.
Temporal phase coding is a plausible mechanism for information transfer during speech perception.
