Ranganath (Ratliff), K. A., & Nosek, B. A. (2008). Implicit attitude generalization occurs immediately, explicit attitude generalization takes time. *Psychological Science, 19,* 249-254. Notes: 1. Only cleaned datasets are provided because raw data files contain sensitive, confidential information (IP addresses, email addresses, and potentially-identifying demographic information). The datasets are SPSS files. 2. The SAS script used for data analysis is not available due to a hard drive failure on the first author's computer in 2008. However, the scriptis nearly identical to that used in Ratliff and Nosek (2011, PSPB, Study 1), which is available on that project page. 3. The .xml files were used to run the studies on Project Implicit. Abstract: People are able to explicitly resist using knowledge about one person to evaluate another from the same group. After exposure to positive and negative behaviors performed by an individual from each of two different groups, participants were introduced briefly to new individuals from the groups. Implicit evaluations of the original individuals readily generalized to the new individuals; explicitly, participants resisted such generalization. Days later, both implicit and explicit evaluations of the original individuals generalized to the new individuals. The results suggest that associative links (e.g., shared group membership) are sufficient for implicit attitude generalization, but deliberative logic (e.g., individual group members are not necessarily the same) can reduce explicit generalization-by-association. When knowledge distinguishing who-did-what is unavailable, such as after forgetting, associative knowledge provides the basis of explicit evaluation. We conclude that a simple association linking one individual to another can produce implicit attitude generalization immediately and explicit attitude generalization eventually.
