This project contains scans of the original TATs, as well as transcriptions of these TATs, collected in an experimental motive arousal study conducted in the late 1940s at Wesleyan University and published as: McClelland, D. C., Clark, R. A., Roby, T. B., & Atkinson, J. W. (1949). The effect of the need for achievement on thematic apperception. Journal of Experimental Psychology, 37, 242-255. The project also includes an EXCEL sheet with David Winter's nAchievement scores, based on the running-text system (Winter, 1991), and an explanation of the experimental-condition codes (U = success-failure condition, A = failure condition, E = relaxed condition). These scores were the basis for the achievement motive data reported in Table 3 of Winter (1991). Please note that most of the TATs were 4-story protocols. For unknown reasons, however, some also featured five stories, but appear to be part of the McClelland et al (1949) experiment, as per the participant codes in David Winter's EXCEL sheet. Therefore, they were included here as scans and transcripts. I would like to thank David Winter for curating and sharing the original TATs and his coding data and Darah Oxford for scanning and transcribing all TATs. The original TATs are now archived at the HuMAN Lab (Friedrich-Alexander University, Erlangen, Germany). OCS, February 21, 2020 References: Winter, D. G. (1991).
