Attitudes and Attitude Change Social Psychology Lecture 3 Dr Amanda Rivis
Learning Outcomes By the end of this lecture, and with independent study, you should be able to: Discuss the origins, structure and functions of attitudes l Evaluate methods for measuring attitudes l Discuss the link between attitudes and behaviour l Discuss theories of attitude change l
The different origins of Attitudes: Classical Conditioning (A) (B) Stimulus 1 (Moth Balls) Stimulus 2 (Visits to Grandmother) Pleasurable Feelings Stimulus 1 (Moth Balls) Pleasurable Feelings
The Different Origins of Attitudes: Instrumental Conditioning Behaviour toward Attitude Object (e. g. , playing with child of another Race) Positive or Negative Reinforcement (+ive = parents approval -Ive = parents’ Disapproval) Positive or Negative Attitude Toward Attitude Object
The Different Origins of Attitudes: Imitation Social Learning Theory (Bandura 1977): ò Attitudes are learned through imitation and modelling. Parents and society influence attitude
Attitude Structure l Three-component model views attitudes as having three components: ¡ Affective = feelings about the attitude object ¡ Behavioural = predisposition to act towards the attitude object in a certain way ¡ Cognitive = beliefs about the attitude object l Any given attitude may be based in lesser or greater amounts on any of these components
Functions of Attitudes l Value-Expressive function ¡ enable us to express who we are and what we believe in l Ego-defensive function ¡ enable us to project internally-held conflicts onto others (e. g. , homophobia) l Knowledge function ¡ enable us to know the world l Utilitarian Function ¡ Enable us to gain rewards and avoid punishment
How are attitudes measured? Overt Attitude Measures Self-report (single-item) attitude measures l Advantages: ¡ ¡ l Easy and quick to administer Relatively cheap Disadvantages: ¡ Responses may not be reliable, e. g. , l l Question wording Mood Social desirability (but see bogus pipeline technique) Assume people have an attitude! (cf. “spontaneous” attitudes)
How are attitudes measured? Overt Attitude Measures Attitude scales Multiple items are used to measure the same construct l Eliminate some of the problems of single-item measures (e. g. , reliability) l Some of the more popular scales include: ¡ Likert scale ¡ Osgood’s Semantic Differential Scale ¡ Expectancy-Value Scale (Fishbein, 1971) l
How are attitudes measured? Example of Expectancy-Value Approach My using birth control pills… Belief Strength Product +3 Outcome Evaluations +1 Is convenient Causes me to gain weight +3 -2 -6 Gives me guilt feelings Enables me to regulate the size of my family +2 -1 -2 +2 +2 +4 Total +3 -1
How are attitudes measured? Covert Measures 2 Covert Attitude Measures (CAM). These measures use physiological arousal to infer attitudes: 2 Electro-myograph (EMG). (Petty & Cacioppo 1981) which may include heart rate & pupil dilation 2 Galvanic Skin Response (GSR) : measures physiological arousal detected through skin resistance (Porier & Lott 1967)
How are attitudes measured? Evaluation of Covert Measures *More objective than self-report measures *Physiological measures (e. g. GSR) can be caused by fear or anger *Physiological measures cannot assess the direction of affective responses
How Well Do Attitudes Predict Behaviour? l Early research evidence suggested a weak to moderate link between attitudes and behaviour (e. g. , La. Piere, 1934; Wicker, 1969) l More recent research has examined moderators of the attitude-behaviour relationship, e. g. , Attitude strength ¡ Direct experience with the attitude object ¡ Attitudinal ambivalence ¡ Correspondence of attitudinal and behavioural measures ¡
How Well Do Attitudes Predict Behaviour? Correspondence of Attitudinal and Behavioural Measures Attitude Measure Attitude-Behaviour Correlation Attitude toward birth control . 08 Attitude toward birth control pills . 32 Attitude toward using birth control pills . 53 Attitude toward using birth control pills during the next two years . 57 Source: Davidson & Jaccard (1979)
How Well Do Attitudes Predict Behaviour: Ajzen’s (1991) Theory of Planned Behaviour (TPB) l This model posits an important mediator of the attitude-behaviour link, namely behavioural ‘intention’ l The TPB holds that attitudes combine with other important factors in predicting intentions and, in turn, behaviour: Perceived social pressure ¡ Factors that may facilitate or inhibit performance of the behaviour ¡
Theory of Planned Behaviour (Ajzen, 1991) Perceived Social Pressure Attitudes Perceived Behavioural Control Intention Behaviour
Theories of Attitude Change: The Yale Attitude Change Approach (Hovland, et al. 1953) According to this approach, attitude change/persuasion influenced by 3 factors: Source – originator of communication l Message – features of communication itself l Audience – characteristics of who is receiving the message l
Theories of Attitude Change: The Yale Attitude Change Approach (Hovland, et al. 1953) l Characteristics ¡ Credibility Expertise l Trustworthiness l ¡ Attractiveness Similarity l Appearance l of Source
Theories of Attitude Change: The Yale Attitude Change Approach (Hovland, et al. 1953) l Message Factors ¡ One-sided ¡ Order vs. Two-sided messages of messages Primacy Effects –vl Recency Effects l ¡ Repetition
Theories of Attitude Change: The Yale Attitude Change Approach (Hovland, et al. 1953) l Characteristics of Audience ¡ Distraction ¡ Intelligence ¡ Self-Esteem (? ) ¡ Age (18 -25 year olds most susceptible) Problem: what conditions determine the relative importance of these factors?
Petty & Cacioppo’s (1986) Elaboration Likelihood (dual-process) Model of Persuasion (ELM) l ELM holds that there are two ‘routes’ to attitude change: route to persuasion occurs when we think critically about message content and are swayed by the strength and quality of its arguments. ¡ Peripheral route to persuasion occurs when we do not do much thinking but are swayed by employing heuristics on the basis of noncontent cues (e. g. , “experts know best”) ¡ Central
The Elaboration-Likelihood Model of Persuasion (Petty & Cacioppo, 1986) Whether persuasion results from the central or the peripheral processing route depends upon: l Ability ¡ e. g. , attention, ‘receptive’ l Motivation ¡ Personal Involvement
The Elaboration-Likelihood Model of Persuasion (Petty & Cacioppo, 1986) Yes Persuasive Communication Central Route to Persuasion Ability & Motivation to pay attention? No Attitude Change Peripheral Route To persuasion
Theories of Attitude Change: Cognitive Dissonance Theory (Festinger, 1957) This theory of self-persuasion holds that: ¡ Cognitive inconsistency creates a state of psychological tension (i. e. , “dissonance”) ¡ Such tension is aversive and motivating (where it poses a threat to the self) ¡ Easiest form of dissonance reduction will be adopted
Cognitive Dissonance Theory and Attitude Change: Justifying Attitude-Discrepant Behaviour Festinger & Carlsmith (1959)
Theories of Attitude Change: Bem’s (1965) Self Perception Theory l According to Bem, attitude change does not need to result from dissonance l People infer their attitudes from their behaviour l Cognitive dissonance when attitude-behaviour discrepancy large self-perception when not so large (Fazio, et al. 1977)
