Authentic, "messy data" contain variability that comes from many sources, such as natural variation in nature, chance occurrences during research, and human error.

Motivated by a Bayesian account, we conducted a training study to investigate this question. Children (45…

To investigate underlying learning mechanisms in relation to the development of dyslexia, event-related potentials to visual standards were recorded in five-year-old pre-reading children at-risk for familial dyslexia (n=24) and their controls (n=14). At the end of second grade the children aged 8 years were regrouped into three groups according to…
