Which is better the IAT or Affective Priming?
Comparison of two Implicit Association Tests
Affective Priming versus Implicit Association test
One criticism of the IAT is that it may merely tap ‘extrapersonal associations’ – it may be a measure of culturally shared assumptions rather than personal attitudes. For example, this would argue that an IAT that detects my strong association between nurse and female is just reflecting my knowledge that society has historically given the role mainly to women, rather than this being my own personal automated attitude (i.e., that nurses ought to be female).
Another criticism of the IAT is the reliance on the switching of blocks. In the first phase, (and in a hypothetical gender bias test), the word female is paired with gender stereotype attributes, e.g., nurse, and the word male with doctor. After the respondent has learned to do this quickly, the categories are then reversed, so that the word female is now paired with words incongruent with the gender stereotype, which make the test much more difficult all of a sudden. This yields significant reaction time differences in the second block – it is a harder task than the first block (not because of an inherent gender bias attitude, but because the respondent had already learned one set of responses, and has to unlearn them and re-learn the new responses in the second block). This is worrying because it means that the effect is prone to changes in procedural issues.
A further problem is that in the IAT, only two dichotomous concepts can be paired (e.g., men vs women, gender stereotypical vs not gender stereotypical), which can be very limiting when one wishes to explore their relationship in more detail. Consequently, the IAT produces a single global gender bias score. However, in affective priming one may have more than just a global score and attributes can be divided into dimensions. This would provide a more detailed picture of such a relationship. So for example, a gender bias test using affective priming will be based on a large number of ‘attributes’ and these can be categorised (e.g., roles, personal qualities, professions, and so on) and this kind of test produces a score for each dimension. Another statistical advantage of the affective priming approach is that one can conduct a factor analysis on the data to reveal how attributes are grouped (grouped spontaneously in the minds of the respondents who took the test). Hence it can yield groups of attributes that together are likely to represent an important feature of the concept begin measured (e.g., nurse, carer, ethical, reliable, hardworking, gentle, and female) – of course this example is too obvious and not so informative, but some patterns can emerge from this approach that weren’t predicted. This is much harder to do with the IAT.
Finally, the reasons why affective priming works is because it is based on assumptions that are highly compatible with what is known about how the brain processes information. Neural network models of the brain are based on mental associations – the stronger the association between two concepts (e.g., female and nurse) the quicker one concept will mentally trigger the other. So that’s four reasons why affective priming is the preferred approach, particularly if you are looking to understand the complex processes in the mind of a consumer.
What can implicit reaction time tests tell us about consumer attitudes and intentions that traditional, explicit, methods can’t?
Implicit reaction time tests, whether based on the implicit association test (the IAT) or on affective priming are on the rise in the world of market research.
Implicit reaction time tests hold the promise to unlock deep seated consumer attitudes. Using the analogy of an archaeological dig (as a colleague of mine likes to use), implicit tests, like Split Second’s Impress Test, can help uncover the hidden treasures buried in the consumer’s mind. This is something that market researchers and brand managers have been looking to use for some time, given the weaknesses of traditional methods.
The way implicit reaction time tests can tap into deep seated feelings has been likened to an archaeological dig.
Yet, market researchers and brand managers can’t work on a promise alone. There is too much to lose – not just the research budget, but the financial consequences of bad research. So an important question is what can implicit reaction time tests tell us about consumer attitudes and intentions that traditional, explicit, methods cannot?
One way to test whether implicit reaction time tests, such as Split Second’s Impress Test, can measure anything useful about consumer attitudes and intentions might be to look for the predictive ability of implicit and explicit tests – are there circumstances in which either or both of these measures are strongly related to the purchasing behaviours of consumers.
There are numerous examples in the peer-reviewed literature demonstrating that in many circumstances implicit attitudes are better predictors of subsequent behaviour than explicit responses provided at the same time. For example, Steinman and Karpinski (2009) found that implicit but not explicit attitudes towards the brand GAP predicted GAP patronage and buying intentions. Brunel, Tietje and Greenwald (2004) showed that implicit methods can detect attitudes about brands that explicit measures cannot (e.g., how different races advocated different patterns of brand preferences implicitly but not explicitly).
Other research includes Priluck and Till (2009) who found that explicit and implicit measures were both good at detecting attitudinal differences between brands when the difference was large or obvious, but only implicit methods could detect differences when they are less obvious. Other research shows that implicit methods in a consumer context are difficult to fake. For example, Chan and Sengupta (2010) found that while the claims of an advertisement were dismissed, implicit responses revealed that the ad had induced favourable attitudes to the brand.
An interesting study published in 2010 by a team of researchers in Italy headed by from Michelangelo Vianello, shows how important it is to assess true feelings as opposed to those that people like to state in order to present themselves in a favourable light. College students were given two different measures of conscientiousness, one was a traditional explicit personality self-report questionnaire and the other was an implicit reaction time test whose attributes focussed on conscientiousness. Half of the students were further told to imagine that they were being tested for their ideal job (one with a good income, low effort, and so on) and the half were not told this. Those with the job-story scored higher on conscientiousness but only on the self-report test. This shows that they could give biased answers and present themselves in a very favourable light. Yet, both groups scored about the same on the implicit measure – this is remarkable because it shows that the implicit measure was not so easy to fake.
Academic studies like this provide very strong evidence of the usefulness of implicit reaction time tests.
