Selective attention to pure tones and speech

Selective attention to lexical tones recruits left dorsal frontoparietal network.

Phonological processing activates a posterior superior region of inferior prefrontal cortex, but questions still remain about the relationship between phonology and this particular region. In this fMRI experiment, subjects were asked to match an intrasyllabic unit (Chinese tones) in an experimental condition vs. whole syllables in a control condition. The only difference between conditions is m...

Infant Auditory Sensitivity to Pure Tones and Frequency-Modulated Tones

It has been suggested that infants respond preferentially to infant-directed speech because their auditory sensitivity to sounds with extensive frequency modulation (FM) is better than their sensitivity to less modulated sounds. In this experiment, auditory thresholds for FM tones and for unmodulated, or pure, tones in a background of noise were measured for 4-month-old infants using a conditio...

Lipreading and covert speech production similarly modulate human auditory-cortex responses to pure tones.

Watching the lips of a speaker enhances speech perception. At the same time, the 100 ms response to speech sounds is suppressed in the observer's auditory cortex. Here, we used whole-scalp 306-channel magnetoencephalography (MEG) to study whether lipreading modulates human auditory processing already at the level of the most elementary sound features, i.e., pure tones. We further envisioned the...

Attention deficits revealed by passive auditory change detection for pure tones and lexical tones in ADHD children

Inattention (IA) has been a major problem in children with attention deficit/hyperactivity disorder (ADHD), accounting for their behavioral and cognitive dysfunctions. However, there are at least three processing steps underlying attentional control for auditory change detection, namely pre-attentive change detection, involuntary attention orienting, and attention reorienting for further evalua...
