Cognitive control in media multitaskers : Two replication studies and a meta-Analysis

Ophir, Nass, and Wagner (2009, Proceedings of the National Academy of Sciences of the United States of America, 106(37), 15583–15587) found that people with high scores on the media-use questionnaire—a questionnaire that measures the proportion of media-usage time during which one uses more than one medium at the same time—show impaired performance on various tests of distractor filtering. Subsequent studies, however, did not all show this association between media multitasking and distractibility, thus casting doubt on the reliability of the initial findings. Here, we report the results of two replication studies and a meta-analysis that included the results from all published studies into the relationship between distractor filtering and media multitasking. Our replication studies included a total of 14 tests that had an average replication power of 0.81. Of these 14 tests, only five yielded a statistically significant effect in the direction of increased distractibility for people with higher scores on the media-use questionnaire, and only two of these effects held in a more conservative Bayesian analysis. Supplementing these outcomes, our meta-analysis on a total of 39 effect sizes yielded a weak but significant association between media multitasking and distractibility that turned nonsignificant after correction for small-study effects. Taken together, these findings lead us to question the existence of an association between media multitasking and distractibility in laboratory tasks of information processing.

Indonesian digital natives: ICT usage pattern study across different age groups

Since its first appearance on early 2000s at the U.S, the idea that a new generation of students called digital natives or net generation has entered the world has been widely discussed by parents and educators alike. It is said that this generation think, socialize, and act differently; and they will alter roles and regulation of work and educational institutes. Now, at the second decade of the 21st century, Indonesia has to ready herself to meet this new generation. In this paper, we compared information and technology (ICT) access, activities within ICT, investment on ICT, and attitude towards ICT between five hundred Indonesian in three different groups: those who born before the 1980s; those who born between 1980s to 1989s, and those who born after the 1990s by ANOVA. We found that there were no difference on information and technology (ICT) access, activities, investment on ICT, and attitude towards ICT between the groups.

In the original article, the number of HMMs and LMMs who took part in the first study was reported to have been 13and 10, respectively (p. 2624).
