The effect of plot explicit, educational explicit, and implicit inference information and coviewing on children's internal and external cognitive processing

摘要

Parental coviewing - the act of being present when a child is watching television - can influence the child's cognitive processing and emotional reactions. This study investigated the role coviewing has on the child's cognitive processing - which is evidenced by the phasic psychophysiological orienting response to three types of information: plot explicit, educational explicit, and implicit inference. An experiment was conducted that measured the heart rate of children (N = 88; mean age = 9.12 years) while watching messages either with or without a parent present in the room. It was predicted, and found, that coviewing leads to greater resource allocation to encoding the message - as indicated by phasic cardiac deceleration, and that information that required internal processing, such as plot explicit or implicit inferential content, leads to greater resources allocated to internal processing - as indicated by phasic cardiac acceleration. Implications for parental mediation strategies and educational television programming are given.
