However, the consequences of changing the selection cutoff dates within a national sport organization are unknown.

The effect of age, metacognition and learning styles on decision making has been scarcely researched among the adult population, and these studies have mostly used data collected from young adults to derive conclusions generalized towards the entire adult population. This research aimed to further differentiate the variance among the adult…

Early identification and intervention are recognised as important elements of the clinical pathway for autism spectrum disorder (ASD). Children with ASD and attention deficit hyperactivity disorder (ADHD) may be diagnosed at a different age than children who only have one of these diagnoses. This systematic review aimed to identify the age at…
