Abstract
This exploratory study examined the heart rates (HR) and skin temperatures (ST) of 18 preschool children while they viewed two clips of everyday children's television (TV) programming. The measurements were made in a day care setting, in a naturalistic environment designed to mimic the real world of children's TV viewing. The purpose of the study was to determine whether cardiovascular and autonomic arousal to TV programming might occur in some children. Since a large body of psychosocial literature addresses the affects of TV violence on children, HR and ST were examined during exposure to scenes from Mr. Roger's Neighborhood and G.I. Joe cartoons. The Mr. Roger's clip was slow, rhythmic, prosocial, and nonviolent, while the G.I. Joe clip was fast-paced, staccato, colorful, and full of verbal and action violence. The study found a significant effect of exposure to the cartoon violence on HR, with HR increasing. ST decreased, but not significantly, and there was a significant effect of time on the ST, due possibly to habituation. This finding has relevance to nursing assessment, intervention, and education of parents and children, since TV viewing is a pervasive cultural phenomenon. The possibility of excessive or inappropriate autonomic and cardiovascular responsiveness in some children to TV must be considered.
