Summary
This study explored auditory attention networks using pitch discrimination and sound localization tasks. Sound localization shows promise for assessing all three auditory attention networks in a single task.
Area of Science:
- Cognitive Neuroscience
- Auditory Perception
- Neuroscience
Background:
- The Attention Network Test (ANT) is a standard for assessing visual attention.
- Investigating auditory attention networks is crucial for understanding sensory processing.
- Current methods for auditory attention assessment are limited.
Purpose of the Study:
- To develop and validate methods for assessing auditory attention networks.
- To compare auditory attention network performance with the established visual ANT.
- To identify tasks suitable for measuring alerting, orienting, and executive control in auditory attention.
Main Methods:
- Participants completed pitch discrimination and sound localization tasks.
- Performance metrics were analyzed to assess alerting, orienting, and executive control.
- Auditory task performance was compared to established visual ANT data.
Main Results:
- Alerting was elicited in both tasks but effects were unrelated.
- Sound localization robustly elicited orienting, unlike pitch discrimination.
- Executive control was assessed in both tasks, but effects were unrelated.
- Sound localization executive control tapped a shared attention network system.
Conclusions:
- Auditory attention network measures are largely task and modality specific.
- Sound localization is a promising single task for assessing all three auditory attention networks.
- Findings contribute to understanding the modality-specific nature of attention networks.

4.5K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

01:11The Auditory Ossicles
3.1K
The auditory ossicles of the middle ear transmit sounds from the air as vibrations to the fluid-filled cochlea. The auditory ossicles consist of two malleus (hammer) bones, two incus (anvil) bones, and two stapes (stirrups), one on each side. These bones develop during the fetal stage and are the ones to ossify first. They are fully mature at birth and do not grow afterward.
The aptly named stapes look very much like a stirrup. The three ossicles are unique to mammals, and each plays a role in...

Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...

01:15Auditory Pathway
7.3K
Auditory pathways constitute the complex neural circuits responsible for transmitting and interpreting auditory information from the peripheral auditory system to the brain. Sound waves are initially captured by the outer ear, funneled through the ear canal, and reach the tympanic membrane (eardrum). These vibrations are transmitted via the middle ear's ossicles to the inner ear's cochlea.
When viewed cross-sectionally, the cochlea reveals the scala vestibuli and scala tympani flanking...

01:17Auditory Perception
1.1K
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...
