Researchers have spent decades studying the link between aptitudes and various educational treatments. An aptitude was defined as a measurable underlying personal characteristic that resulted in a predisposition to respond to tasks in a specific way (e.g., intelligence, personality, motivation, and learning styles; R. E. Snow, 1991). Researchers have long interpreted aptitudes to be fixed traits that were most often assessed with cognitive measures such as intelligence and memory (Snowman, McCown, & Biehler, 2008). The goal of the current research is to compare acquisition of words to measures of memory and to less fixed relevant traits such as reading skills. Below, we will discuss research around aptitudes and educational treatments, skills and educational treatments, and acquisition of words.
