Summary
Deaf readers activate sign language translations while reading. Handshape is crucial, influencing early sign activation and reading speed in Chinese signers of Hong Kong Sign Language (HKSL).
Area of Science:
- Cognitive Science
- Linguistics
- Deaf Studies
Background:
- Deaf readers unconsciously access sign language translations of written words.
- The influence of specific sign phonological parameters on reading processes remains under-explored.
Purpose of the Study:
- To investigate how sign phonologically related previews affect reading in deaf Chinese signers.
- To examine the role of handshape, location, and movement parameters in parafoveal processing.
Main Methods:
- Utilized a parafoveal preview paradigm with adult deaf signers of Hong Kong Sign Language (HKSL).
- Compared reading times for target words preceded by four types of sign phonologically related previews.
Main Results:
- Handshape parameter was critical for early sign activation.
- Reading times increased when previews shared handshape, movement, or all three parameters (handshape, location, movement).
- Reading times decreased when previews shared location with either handshape or movement.
Conclusions:
- Orthographic processing activates phonological parameters of sign language during reading.
- Sign phonological parameters (handshape, location, movement) differentially impact parafoveal processing in deaf signers.

01:17Auditory Perception
894
The auditory system is essential for sound perception, utilizing various critical structures. When sound waves enter the outer ear, they travel through the ear canal and cause the eardrum to vibrate. These vibrations are then transmitted to the middle ear, where three tiny bones – the malleus, incus, and stapes – amplify the sound. This amplification is crucial, as it ensures that the sound vibrations are strong enough to be conveyed to the inner ear. These vibrations then reach the...

01:21Perceiving Loudness, Pitch, and Location
819
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...

01:01Perception of Sound Waves
5.3K
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...

01:25Factors Affecting Perception
2.5K
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.
