1、學習匯報2 基于技術接受模型的行為理論概述 技術接受模型Theory of Reasoned Action (TRA) Core ConstructsDrawn from social psychology, TRA is one of the most fundamental and influential theories of human behavior. It has been used to predict a wide range of behaviors (see Sheppard et al. 1988 for a review). Davis et al.(1989) ap

2、plied TRA to individual acceptance of technology and found that the variance explained was largely consistent with studies that had employed TRA in the context of other behaviors.Attitude TowardBehaviorSubjective NormTechnology Acceptance Model (TAM)Core ConstructsTAM is tailored to IS contexts, and

3、 was designed to predict information technology acceptance and usage onthe job. Unlike TRA, the final conceptualization of TAM excludes the attitude construct in order to better explain intention parsimoniously. TAM2 extended TAM by including subjective norm as an additional predictor of intention i

TAM has been widely applied to diverse set of technologies and users.Perceived UsefulnessPerceived Ease of use Subjective NormMotivational Model (MM)Core ConstructsA significant body of research in psychology has supported general motivati

5、on theory as an explanation for behavior. Several studies have examined motivational theory and adapted it for specific contexts. Vallerand(1997) presents an excellent review of the fundamental tenets of this theoretical base. Within the information systems domain, Davis et al. (1992) applied motiva

Attitude Toward BehaviorSubjective Norm Perceived Behavioral ControlPerceived Usefulness Model of PC Utilization (MPCU) Derived largely from Triandis (1977) theory of human behavior, this model presents a competing perspective to that proposed by TRA and TPB. Thompson et al. (1991)adap

8、ted and refined Triandis model for IS contexts and used the model to predict PC utilization. However, the nature of the model makes it particularly suited to predict individual acceptance and use of a range of information technologies. Thompson et al. (1991) sought to predict usage behavior rather t

9、han intention; however, in keeping with the theorys roots, the current research will examine the effect of these determinants on intention. Also, such an examination is important to ensure a fair comparison of the different models. Job-fit Complexity Long-term Consequences Affect Towards Use Social

10、FactorsFacilitating Conditions Social Cognitive Theory (SCT)One of the most powerful theories of human behavior is social cognitive theory (see Bandura 1986). Compeau and Higgins (1995b) applied and extended SCT to the context of computer utilization (see also Compeau et al. 1999); while Compeau and

11、 Higgins (1995a) also employed SCT, it was to study performance and thus is outside the goal of the current research. Compeau and Higgins (1995b) model studied computer use but the nature of the model and the underlying theory allow it to be extended to acceptance and use of information technology i

12、n general. The original model of Compeau and Higgins (1995b) used usage as a dependent variable but in keeping with the spirit of predicting individual acceptance, we will examine the predictive validity of the model in the context of intention and usage to allow a fair comparison of the models.Outc
