Factors Affecting Perception01:25

Factors Affecting Perception

1.7K
Perception is influenced by perceptual set, context, motivation, and emotion. Perceptual set, or perceptual expectancy, refers to the tendency to perceive things in a particular way, influenced by previous experiences and expectations. This phenomenon affects the interpretation of stimuli, creating a set of mental tendencies and assumptions that impact sensory perceptions of sound, taste, touch, and sight.
An illustrative example of a perceptual set is the scenario where an airline pilot told...

Properties of Fourier Transform II01:24

Properties of Fourier Transform II

259
The Fourier Transform (FT) is an essential mathematical tool in signal processing, transforming a time-domain signal into its frequency-domain representation. This transformation elucidates the relationship between time and frequency domains through several properties, each revealing unique aspects of signal behavior.
The Frequency Shifting property of Fourier Transforms highlights that a shift in the frequency domain corresponds to a phase shift in the time domain. Mathematically, if x(t) has...

Perception of Sound Waves01:01

Perception of Sound Waves

4.5K
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...

Perceiving Loudness, Pitch, and Location01:21

Perceiving Loudness, Pitch, and Location

279
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...

Aliasing

Accurate signal sampling and reconstruction are crucial in various signal-processing applications. A time-domain signal's spectrum can be revealed using its Fourier transform. When this signal is sampled at a specific frequency, it results in multiple scaled replicas of the original spectrum in the frequency domain. The spacing of these replicas is determined by the sampling frequency.
If the sampling frequency is below the Nyquist rate, these replicas overlap, preventing the original...

Time and frequency -Domain Interpretation of Phase-lag Control01:21

Time and frequency -Domain Interpretation of Phase-lag Control

120
Phase-lag controllers are widely used in control systems to improve stability and reduce steady-state errors. A dimmer switch controlling the brightness of a light bulb serves as a practical example of phase-lag control, gradually adjusting the bulb's brightness. Mathematically, phase-lag control or low-pass filtering is represented when the factor 'a' is less than 1.
Phase-lag controllers do not place a pole at zero, but instead influence the steady-state error by amplifying any...

Summary

Temporal frequency impacts time perception differently across senses. Auditory stimuli at 10 Hz shorten perceived time, while higher frequencies lengthen it, unlike visual stimuli which consistently lengthen perceived time.

Area of Science:

  • Cognitive psychology
  • Neuroscience
  • Sensory perception

Background:

  • Time perception is influenced by stimulus temporal frequency.
  • Previous research assumed monotonic effects of temporal frequency modulation on time perception.

Purpose of the Study:

  • To investigate the non-monotonic and modality-dependent effects of temporal frequency on time perception.
  • To examine time distortion effects across auditory and visual modalities.

Main Methods:

  • Four experiments manipulated temporal frequency (steady, 10, 20, 30/40 Hz) in auditory and visual stimuli.
  • Participants perceived duration of intermittent stimuli compared to steady stimuli.

Main Results:

  • Auditory 10 Hz stimuli were perceived as shorter than steady stimuli.
  • Increasing auditory temporal frequency led to lengthened perceived duration.
  • Visual 10 Hz stimuli were perceived as longer than steady stimuli, with further lengthening at higher frequencies.

Conclusions:

  • Temporal frequency affects time perception in a non-monotonic manner.
  • Differential time distortion effects were observed between auditory and visual modalities.
  • Findings challenge previous assumptions of monotonic temporal frequency effects.
