Attitudes and Behaviour Flashcards
What are the 4 factors of the TPB?
attitudes PBC perceived norms (replaced subjective norms in TRA) - injunctive norms - descriptive norms
What are attitudes?
subjective evaluations about the outcome of a given action
What is perceived behavioural control?
perception of one’s ability to engage in particular behaviours
internal; skill, willpower
external; time, opportunity
What are injunctive norms?
the perception that significant others will approve of a given behaviour
What are descriptive norms?
the perceptions that significant others are also engaging in a particular behaviour
What are the two views of the attitude-behaviour relationship?
Ajzen & Fishbein
optimism; measures of attitude are strongly related to action
Wicker
pessimism; measures of attitude are unrelated or only slightly related to behaviours
Which study supports an attitude-behaviour gap?
LaPiere (1934)
Chinese couple went to restaurants
face-to-face only 1/251 establishments wouldn’t serve them
on the phone 92% said they wouldn’t allow it
* norm of politeness in face-to-face interactions
What is correspondence and why is it important?
it is making sure that the measurement is effective and specific enough, the attitude-behaviour gap can exist if correspondence is not met
Which studies show the importance of correspondence?
Weigel & Newman (1976)
a substantial attitude-behaviour correlation can only be obtained when the attitude measure has established quality and is comparable to the behavioural measures
Davidson & Jaccard (1979)
strongest attitude-behaviour correlations were found for the most specific attitude measurement; taking birth control pills in the next 2 years
What is the Theory of Reasoned Action?
Ajzen & Fishbein (1980)
attitudes and subjective norms influence behavioural intention
explicitly deals with purely volitional behaviours
What is a subjective norm?
the perception of important others opinions on whether a behaviour should be performed (normative beliefs) AND the social pressures to perform or not perform that behaviour (motivation to comply)
What is the expectancy-value framework?
subjective expected utility approaches in decision making
What is a criticism of the TPB?
it is overly rational, neglecting affective factors
What factors can cause an intention-behaviour gap?
attitude strength
ambivalence
indifference
imminence of events
How does attitude strength affect intention and behaviour?
some attitudes can be stable and consequential, others can be flexible with few important effects depends on; - durability - influence on behaviour - resistance to persuasion effects
What is ambivalence?
having both positive and negative feelings towards a construct
- approach-avoidance conflict
What is indifference?
having no opinion so masking this fact by making hastily fabricated affective judgements
