Rankings of Journals in Social-Personality Psychology with Respect to their Statistical Power.
JP = Journal of Personality, JRP = Journal of Research in Personality, PSPB = Personality and Social Psychology Bulletin, JPSP = Journal of Personality and Social Psychology, JESP = Journal of Experimental Social Psychology, PS = Psychological Science (social/personality articles only). The hashed line represents the statistical power (80%) recommended by Cohen (1992).
