DESCRIPTION:Abstract: Decades of research have amassed an impressive body o
 f knowledge on sources of variability in eye-movement control in reading. 
 Major sources include text characteristics (i.e. properties of letters\, m
 orphemes\, words\, sentences\, or passages) and participant characteristic
 s (clinical status\, age\, reading experience\, IQ\, working memory\, etc.
 ). As a result\, word length\, frequency of occurrence and predictability 
 in context – and more recently\, component skills of reading (Reichle et a
 l.\, 2013) – are routinely used as benchmark predictors of eye-movements a
 nd core parameters of computational models of eye-movement control (Reichl
 e et al.\, 2006\; Engbert\, 2005). However\, little effort has been alloca
 ted to establishing  how important individual predictors or (sets of predi
 ctors) of eye-movements are relative to other predictors (or other sets). 
 Yet such information is crucial for highlighting which aspects of linguist
 ic complexity and individual ability and skill are central for efficient r
 eading and when in the time-course of reading they are engaged.\n	\n	I will 
 present a study in which the non-parametric machine-learning technique of 
 random forests evaluates the relative importance of a large set of text-re
 lated and participant-related variables as predictors of eye-movements and
  comprehension scores observed during text reading. I will demonstrate the
  utility of this method both for the comprehensive description of individu
 al differences and language-driven variability in reading behavior unfoldi
 ng over time\, and for the generation of specific hypotheses that can be p
 ursued with the confirmatory analysis.\n
