Science behind the app

Dr Implicit is an app based on neuroscientific and psychological principles. This is a fun scaled down version for entertainment purposes.

This app is based on the affective priming paradigm (Fazio, R. H., Sanbonmatsu, D. M., Powell, M. C., & Kardes, F. R. (1986). On the automatic activation of attitudes. Journal of Personality and Social Psychology, 50, 229–238. doi:10.1037/0022-3514.50.2.229).

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., Milan and Fashion) the quicker one concept will mentally trigger the other.

How does an implicit reaction time test work?

The commercial test is itself based on the evaluative priming paradigm in academic research (e.g., Fazio, et al., 1986)1. The first phase of the test is to detect target emotion words as belonging to either one category (e.g., Happy) or another (e.g., Sad).  On each trial in this first phase, the word appears and the respondent has to press one key for happy words and another key for sad words. This is a very easy task, and respondents can do this very quickly with few errors.

In the second phase, the task is the same but the target emotion words are preceded very briefly by ‘primes’. These primes are either congruent with the target word (the prime is Joy when the target is Happy, or the prime is Gloomy when the target is Sad) or incongruent (the prime is Gloomy when the target is Happy, or the prime is Joy when the target is Sad). So on some trials the respondent might see the word Joy flash on the screen followed by Happy. They respond to the second word by pressing a key for happy words. The task can be performed quicker and with fewer errors in this case because the prime and the target are congruent. On other trials, the word Gloomy is flashed on the screen followed by Happy. This time, because Gloomy and Happy are incongruent, respondents are a little slower to detect Happy in their key press. The response may be slower by only a split second, yet when repeated over several trials and over many respondents, it would become ‘statistically significant’.

So let’s take this test into the commercial arena. The primes might be the same (Joy and Gloomy) but this time the targets could be Adidas and Nike. Respondents who have a strong preference for Adidas over Nike are likely to be quicker to respond to Joy > Adidas than Joy > Nike, and quicker to respond to Joy > Adidas than Gloomy > Adidas.

In implicit response testing, we broaden the primes to refelct attributes related to brand equity, such as Trusted, Modern, Friendly, Cool, and so on. The targets can be more than just brands, and can be pack designs, celebrities, claims, and so on.

In fact, there is not only one type of implicit test but several, with each being designed to measure a specific aspect of consumer evaluation, such as ad testing, pack testing, claims testing, NPD testing, celebrity endorsement testing, as well as brand positioning.
