q2 i? In both groups the proportion of correctly identified targets dropped linearly with level: adults showed a best-fit slope of -0.06 (R2 = 0.87, levels 5–10) and children a slope of -0.17 (R2 = 0.91, levels 3–9). → Kimiko Ryokai 2013

q2 · i? · design · r2

Regression analysis of proportion correct versus level (Fig. 4). All participants performed perfectly on levels 1–3; at level 4 the groups deviated, with children dropping to around 0.8 proportion correct, and children's performance was significantly lower than adults' at each level beyond 4.

"In children, there was a linear drop between level 3 and level 9 with a best fit linear slope of -0.17 and an R2 of 0.91. Therefore, children's performance dropped more steeply as game level increased compared to that of adults."

Discussion¶

Related Claims¶

• In one quasi-experimental VR shooting study (n = 50), reported in a review, rule-based dynamic difficulty outperformed progressive difficulty
• No consistent learning effect of repeated TrackFX gameplay was found across children, though 37% showed positive performance slopes and improvement reached an asymptote after six sessions
• Children aged 30–58 months tracked on average 1 target among 2 distractors, with a slight trend for older children to reach higher thresholds
• Adding distractors made the MOT game substantially more difficult for children than adults, interpreted as immature attentional inhibition of distractors
