Bottom Line: In 2008, there were increases in the number of errors in groups from each age range.The comparison also revealed that overall error rates peaked at later ages in the 2008 subjects.While a lifestyle questionnaire revealed several differences in factors such as bedtimes and hours spent watching TV, analysis did not reveal a significant correlation.

ABSTRACT
This research, conducted in 1998 and 2008, uses go/no-go data to investigate the fundamentals of cognitive functioning in the inhibitory control ability of Japanese children. 844 subjects from kindergarten to junior high school participated in go/no-go task experiments. Performance of go/no-go tasks, which are frequently used to investigate response inhibition, measures a variety of cognitive components besides response inhibition. With normal brain development, the ability to inhibit responses improves substantially in adolescence. An increase over time in the error rate during the go/no-go tasks of subjects of the same age indicates that these processes are not functioning properly. Comparisons between the 1998 and 2008 data revealed several differences in error rates. In 2008, there were increases in the number of errors in groups from each age range. The comparison also revealed that overall error rates peaked at later ages in the 2008 subjects. Taken together, these results show changing conditions in the inhibitory function of the prefrontal cortex. However, the reason for these changing conditions remains unclear. While a lifestyle questionnaire revealed several differences in factors such as bedtimes and hours spent watching TV, analysis did not reveal a significant correlation.

Figure 4: Superimposed results for 1998 (black line) and 2008 (red line). Significant differences are denoted with **: p < 0.01, ***: p < 0.001.

Mentions: The results of 1998 and 2008 are superimposed in Figure 4. Although the overall patterns are similar, the numbers of errors in 2008 tended to be greater than those of 1998. The greatest difference for the different years of investigation was found in G11; the average number of erroneous responses was 3.4 in 1998, as opposed to 6.8 in 2008. The effect of the research year was statistically significant [F(1,198) = 14.7, p < 0.001]. A post-hoc analysis based on a Poisson distribution indicated that the 2008 results for G5, G8, G10, and G11 were statistically higher than those of 1998 [p < 0.001].
