The present paper analyzes the general way in which cognitive perspectives approach reading comprehension and offers an alternative for the study of this concept. From the Interbehavioral perspective reading comprehension is characterized as reading adjustment, which can be structured in five different levels of complexity. Such a characterization allows new forms of evaluation which makes it possible to identify functional differences in reading adjustment. A brief review of the research program for the study of reading adjustment as well as its prospective are included.
