Abstract
A brief version of the Implicit Association Test (BIAT) has been introduced. The present research identified analytical best practices for overall psychometric performance of the BIAT. In 7 studies and multiple replications, we investigated analytic practices with several evaluation criteria: sensitivity to detecting known effects and group differences, internal consistency, relations with implicit measures of the same topic, relations with explicit measures of the same topic and other criterion variables, and resistance to an extraneous influence of average response time. The data transformation algorithms D outperformed other approaches. This replicates and extends the strong prior performance of D compared to conventional analytic techniques. We conclude with recommended analytic practices for standard use of the BIAT.
Highlights
In 7 studies and multiple replications, we investigated analytic practices with several evaluation criteria: sensitivity to detecting known effects and group differences, internal consistency, relations with implicit measures of the same topic, relations with explicit measures of the same topic and other criterion variables, and resistance to an extraneous influence of average response time
The brief version of the Implicit Association Test (BIAT) had the best average ranking (2.34), slightly better than the Implicit Association Test (IAT) (2.39). These results suggest that the BIAT is a highly useful measure for research application
Goodfocal retained a clear advantage. These results suggest that attitude BIATs may be much more effective by using good as the constant focal category and bad as the constant non-focal category
Summary
2,358 study sessions of the Attitudes 3.0 dataset included the politics Brief IAT with at least 4 completed blocks for either good-focal or bad-focal tasks. In the Brief IAT, two categories (e.g., Democrats and good words) are "focal". Stimulus items appear one at a time in the middle of the screen and participants must categorize the stimulus items as either belonging to one of the focal categories (press the ‘i’ key) or not (press the ‘e’ key). If the participant makes an error, a red "X" appears below the stimulus and the trial continues until the correct key is pressed. The stimulus items that appeared but did not belong to the focal categories were always the contrasting stimuli for the other tasks (e.g., Republicans and bad words when Democrats and good words were the focal categories)
