Explain the TRA
The TRA model was proposed in 1975 by Fishbein and Azjen. It focuses on the construction of a system of observation of two groups of variables, which are:
• attitudes defined as a positive or negative feeling in relation to the achievement of an objective;
• subjective norms, which are the very representations of the individuals’ perception in relation to the ability of reaching those goals with the product.
Explain the TPB
The Theory of Planned Behaviour (TPB) is an extension of the Theory of Reasoned Action (TRA) (Fishbein & Ajzen 1975, Ajzen & Fishbein 1980). Both models are based on the premise that individuals make logical, reasoned decisions to engage in specific behaviours by evaluating the information available to them. The performance of a behaviour is determined by the individual’s intention to engage in it (influenced by the value the individual places on the behaviour, the ease with which it can be performed and the views of significant others) and the perception that the behaviour is within his/her control.
According to the TPB, any action a person takes is guided by three types of considerations:
• behavioral beliefs (beliefs about the probable consequences of the practiced behavior)
o Behavioral beliefs normally result in a favorable or unfavorable attitude toward a specific behavior
• normative beliefs (beliefs about the normative expectations of other people)
o normative beliefs result in perceived social pressure or subjective norms
• control beliefs (beliefs about the presence of factors that may enable or obstruct the performance of the behavior).
o control beliefs trigger perceived behavioral control
Explain the intention-behavior gap
What intentions are more likely to fail?
What are inclined abstainers?
What could decrease the intention behavior gap of DRS?
If the process was easier, deposit centers conveniently placed
• Choice architecture to encourage action instead of just intention
• Nudges to remind people to do it
• Increase awareness of environmental consequences to make the intention stronger
• What can you lose by not doing it? (loss aversion)
Explain the theory of cognitive dissonance
How could TPB be used in this study?
What could cause cognitive dissonance when using the DRS?
