TAM is an adaptation of the Theory of Reasoned Action (TRA) to the field of IS. TAM posits that perceived usefulness and perceived ease of use determine an individual's intention to use a system with intention to use serving as a mediator of actual system use. Perceived usefulness is also seen as being directly impacted by perceived ease of use. Researchers have simplified TAM by removing the attitude construct found in TRA from the current specification (Venkatesh et. al., 2003). Attempts to extend TAM have generally taken one of three approaches: by introducing factors from related models, by introducing additional or alternative belief factors, and by examining antecedents and moderators of perceived usefulness and perceived ease of use (Wixom and Todd, 2005). In a recent paper, [https://www.researchgate.net/publication/313426540_Controlling_for_Lexical_Closeness_in_Survey_Research_A_Demonstration_on_the_Technology_Acceptance_Model Gefen and Larsen (2017)] demonstrated that TAM's construct relationships primarily emerge from semantic relationships between its questionnaire items.

A Theory explaining their findings is described at [[Semantic theory of survey response]].

TRA and TAM, both of which have strong behavioural elements, assume that when someone forms an intention to act, that they will be free to act without limitation. In practice constraints such as limited ability, time, environmental or organisational limits, and unconscious habits will limit the freedom to act.
