Research and descriptive studies of the active reader (one who starts reading early in life with a broad range of interests and continues this behavior) are of particular interest, because they identify salient characteristics and acquired traits of people who like to read. For example, the mature reader has been characterized as being able to classify, make inferences from statements given in the text, and adapt a reading style and speed to the nature of the text and to the reader's purpose. Among the traits identified for the gifted reader are the following: enjoys reading, is an avid reader, reads widely, learned to read early, is a self-taught reader, reads more and better books than age peers, reads above grade level by at least two years, selects difficult books for reading, and enjoys information books. On the topic of personality characteristics concerning poor and good readers, it has been reported that poor readers are socially naive and less serious; they are also less exacting and more lax. Active readers are known to have greater depth of emotional resources. Studies of so-called adult, active readers repeat many of the characteristics found among preschool, fluent readers. For reading and study skills teachers, a knowledge of these characteristics and the related research studies may be an aid in providing prompt remedial strategies. Teachers are also in a better position to evaluate their students and to provide helpful techniques when they know and understand developmental factors. (HOD)
