Individuals with amnestic mild cognitive impairment (aMCI), a prodromal stage of Alzheimer's disease and other dementias, show inhibition deficits in addition to episodic memory. How the latent processes of selective attention (i.e.

Cochlear implantation is a well-established method for restoring hearing sensation in individuals with severe to profound hearing loss. It significantly improves verbal communication for many users, despite substantial variability in patients' reports and performance on speech perception tests and quality-of-life outcome measures. Such variability in outcome measures remains several years after implantation and could reflect difficulties in attentional regulation.

Does precision in auditory perception predict precision in subsequent memory (i.e., mnemonic discrimination) in aging? This study examined if the mismatch negativity (MMN), an electrophysiological marker of change detection and encoding, relates to age differences in mnemonic discrimination.

Article Synopsis
  • Evidence indicates that the motor system plays a role in how we perceive speech, particularly in different contexts.
  • In a study with 32 participants, researchers found that the left ventral primary motor cortex and other brain regions activated together when identifying syllables, especially when the syllables were different.
  • While the motor cortex is essential for processing phonological differences, it does not seem to help compensate for difficulties in hearing speech amid noise, suggesting that auditory and motor areas work together to shape our speech perception.

The relationship between speech production and perception is a topic of ongoing debate. Some argue that there is little interaction between the two, while others claim they share representations and processes. One perspective suggests increased recruitment of the speech motor system in demanding listening situations to facilitate perception.
