Implicit measures with reproducible results: The implicitMeasures package

Abstract

In the past few decades, there has been a growing interest in the possibility of assessing people’s attitudes, preferences, self-esteem, opinions, and other social-psychological constructs, without directly asking them. This was made possible by the advent of what are called implicit measures. Implicit measures are generally based on the speed and accuracy with which respondents perform the same categorization task in contrasting conditions. The assumption underlying their functioning is that respondents’ performance will be faster and more accurate in the condition that is consistent with their attitudes, opinions, or preferences. The construct of interest is inferred from the difference in the response times between the associative conditions.
