Media multitasking is associated with distractibility and increased prefrontal activity in adolescents and young adults.
The current generation of young people indulges in more media multitasking behavior (e.g., instant messaging while watching videos) in their everyday lives than older generations. Concerns have been raised about how this might affect their attentional functioning, as previous studies have indicated that extensive mediamultitasking in everyday life may be associated with decreased attentional control. In the current study, 149 adolescents and young adults (aged 13-24 years) performed speech-listening and reading tasks that required maintaining attention in the presence of distractor stimuli in the othermodality or dividing attention between two concurrent tasks. Brain activity during task pe…
Cortical processing of musical sounds in children with Cochlear Implants
Abstract Objective We studied the neurocognitive mechanisms of musical instrument sound perception in children with Cochlear Implants (CIs) and in children with normal hearing (NH). Methods ERPs were recorded in a new multi-feature change-detection paradigm. Three magnitudes of change in fundamental frequency, musical instrument, duration, intensity increments and decrements, and presence of a temporal gap were presented amongst repeating 295 Hz piano tones. Independent Component Analysis was utilized to remove artifacts caused by the Cochlear Implants. Results The ERPs were similar in the two groups across all perceptual dimensions except for intensity increment deviants. CI children had s…
