Loud Snoring

Loud snoring is a harsh, noisy sound produced during sleep when airflow causes relaxed tissues in the throat and upper airway to vibrate. It often becomes louder when airway narrowing increases, such as during deep muscle relaxation or when sleeping on the back, and may occur with disrupted breathing. In psychology, loud snoring matters because it can fragment the sleeper’s rest and disturb a bed partner, contributing to daytime fatigue, irritability, reduced attention, mood changes, and relationship strain. Studying its behavioral and emotional effects can support sleep assessment, communication strategies, and referral for evaluation when snoring is persistent or accompanied by breathing pauses.

Perceiving Loudness, Pitch, and Location

0 Views •

2024

The human brain perceives pitch through two primary mechanisms reflected in place theory and frequency theory. Each mechanism describes how sound waves are interpreted as specific pitches by the brain, offering insights into the intricate processes of auditory perception. Place theory, or place coding, suggests that different pitches are heard because various sound waves activate specific locations along the cochlea's basilar membrane. The brain determines the pitch of a sound by identifying...

2016

Here, we present a protocol to measure, with high spatial resolution, the unsteady surface pressure in turbulent flows. This method demonstrates the construction of a remote microphone probe (RMP) and the determination of its frequency-dependent, complex transfer function. An analytical determination of the dynamic response is presented and validated.

Anxiety Testing

2023

Anxiety is a commonly observed behavioral disorder that stems from fear. It is described as increased restlessness, or unpleasant feelings of fear over anticipated events. Experimenters often use rodent models to better understand anxiety disorders in humans. They use different paradigms, like exposing rodents to bright spaces or loud sounds, which are known to induce fear. These tests combined with other interventions such as surgery or drug-administration may assist researchers in pinpointing...

Objective assessments of the physiological mechanisms that support speech are needed to monitor disease onset and progression in persons with ALS and to quantify treatment effects in clinical trials. In this video, we present a comprehensive, instrumentation-based protocol for quantifying speech motor performance in clinical populations.

The Staircase Procedure for Finding a Perceptual Threshold

2023

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University Psychophysics is the name for a set of methods in perceptual psychology designed in order to relate the actual intensity of stimuli to their perceptual intensity. One important aspect of psychophysics involves the measurement of perceptual thresholds: How bright does a light need to be for a person to be able to detect it? How little pressure applied to the skin is detectable? How soft can a sound be and still be heard? Put...
