Yesterday we talked about the theory of reasoned action by Martin Fishbein and Icek Ajzen (1975, 1980) in a Communication Theory session.
The result is that I feel totally lost between all these new notions, which are: normative beliefs, subjective norms, behavioural beliefs, control beliefs, perceived behavioural control etc.
SO, that’s why I decide today to define each of these term to make a sens of it !
‘A behavioral belief is the subjective probability that the behavior will produce a given outcome. Although a person may hold many behavioral beliefs with respect to any behavior, only a relatively small number are readily accessible at a given moment. It is assumed that these accessible beliefs — in combination with the subjective values of the expected outcomes — determine the prevailing attitude toward the behavior. Specifically, the evaluation of each outcome contributes to the attitude in direct proportion to the person’s subjective probability that the behavior produces the outcome in question’ (Azjen)
to clarify: those accessible beliefs + subjective values ==> determine this attitude that explain this behaviour
Well, it’s not that clear
Attitude toward the behaviour
‘Attitude toward a behavior is the degree to which performance of the behavior is positively or negatively valued. Attitude toward a behavior is determined by the total set of accessible behavioral beliefs linking the behavior to various outcomes and other attributes.’ (Ajzen)
‘Normative beliefs are individuals’ beliefs about the extent to which other people who are important to them think they should or should not perform particular behaviors.’
To clarify: if I go to a wedding and choose not to sleep in the same hotel than my family, they might find this weird and unpolite, so they may want me to choose the same hotel = normative beliefs
‘It is assumed that these normative beliefs — in combination with the person’s motivation to comply with the different referents — determine the prevailing subjective norm.’ (Ajzen)
Normative beliefs + motivation to comply ==> determine the subjective norms
Subjective norm is the perceived social pressure to engage or not to engage in a behavior. It is assumed that subjective norm is determined by the total set of accessible normative beliefs concerning the expectations of important referents. Specifically, the strength of each normative belief is weighted by motivation to comply with the referent in question
To clarify: during a business travel this person will choose the same luxurious hotel than his/her colleagues rather than the cheapest one because otherwise he/she would feel ashamed/ excluded by them = subjective norms
Control beliefs have to do with the perceived presence of factors that may facilitate or impede performance of a behavior. It is assumed that these control beliefs — in combination with the perceived power of each control factor — determine the prevailing perceived behavioral control. Specifically, the perceived power of each control factor to impede or facilitate performance of the behavior contributes to perceived behavioral control in direct proportion to the person’s subjective probability that the control factor is present.
To clarify: this hotel is too expensive for my budget, but i’m on Holidays I can enjoy it anyways = cpntrol beliefs
Perceived behavioral control
‘Perceived behavioral control refers to people’s perceptions of their ability to perform a given behavior. It is assumed that perceived behavioral control is determined by the total set of accessible control beliefs, i.e., beliefs about the presence of factors that may facilitate or impede performance of the behavior. ‘ (Ajzen)
To clarify: when a smoking person says “I don’t think I am addicted because I can really just not smoke and not crave for it,” = perceived behavioral control
Intention is an indication of a person’s readiness to perform a given behavior, and it is considered to be the immediate antecedent of behavior
Behavior is the manifest, observable response in a given situation with respect to a given target.
