Viewing Fantastical Events Versus Touching Fantastical Events: Short-Term Effects on Children's Inhibitory Control.

Three pretest-posttest experiments were conducted to compare the effects of viewing versus interacting with either fantastical or real events on 4- and 6-year-old children's inhibitory control. Experiment 1 (N = 72) suggested that although viewing fantastical events had a negative effect on inhibitory control, interacting with them produced no such disruption. Experiment 2 (N = 17) also found that children's inhibitory control decreased after viewing fantastical events but not after interacting with them. In addition, functional near-infrared spectroscopy (fNIRS) data showed that viewing fantastical events resulted in greater activation in the dorsolateral prefrontal cortex. Experiment 3 (N = 72) showed that children's inhibitory control increased after viewing and interacting with real events. The implications for studying the effects of mobile devices are discussed.
