While theories of adult learning and motivation are often framed as being either biological, psychological, or sociocultural, they represent a more complex, integral process. To gain a more holistic perspective of this process, a study was designed to concurrently investigate relationships between a biological factor (age), psychological factors (motivation for training, perceived work limitations), and sociocultural factors (occupation, purpose of training, and work habits). The Assessment of Adult Literacy (NAAL) was used to elicit information about these factors in regards to work training. Data obtained was statistically correlated to age using the Spearman rank correlation coefficient. Results suggest that the interaction of multiple variables governs several shifts in motivation and need for training as adults age. Contrary to traditional theories of adult education, data suggest that a mixture of pedagogical and andragogical teaching styles is necessary for adult learners.
