Connection-based and object-based grouping in multiple-object tracking: A developmental study.

However, our results did not reveal anything to suggest that participants learned to selectively attend to relevant information, as no evidence was found to suggest that task learning was dependent on the grouping type at hand (and results only showed a marginally significant main effect of trial number).

Pearson product–moment correlations between the participants’ age (in months) and the Dumbbell ( r = −.186, p = .054), Necker Cube ( r = −.380, p < .0001), generic grouping ( r = −.137, p = .165), connection‐based ( r = −.064, p = .520), or 3D object‐based ( r = −.427, p < .0001) grouping interference scores were mixed, with some not significant and others highly significant, suggesting that grouping interference may somewhat reduce with increasing age.
